ITEM 3 - LEGAL PROCEEDINGS
On March 28, 2016, AgaMatrix, Inc., or AgaMatrix, filed a patent infringement lawsuit against us in the U.S. District Court for the District of Oregon, asserting that certain of our products infringe three patents held by AgaMatrix. (After filing suit, AgaMatrix reorganized its business and the Court granted AgaMatrix’s motion to substitute the newly created entity WaveForm Technologies, Inc., as the plaintiff following AgaMatrix’s transfer of the three asserted patents to WaveForm.) DexCom filed petitions for inter partes review with the Patent Trial and Appeal Board, or PTAB, of the U.S. Patent and Trademark Office, challenging each of the three asserted patents as being unpatentable in view of prior art. The PTAB issued a Final Written Decision for each of the first two patents on February 28, 2018, where the PTAB found the majority of asserted claims from the first patent unpatentable and the remaining claims under review not unpatentable. The PTAB found all claims under review from the second patent not unpatentable. On September 12, 2018, the PTAB found all of the asserted claims in the third patent unpatentable. In October 2018, we filed in the District Court a motion for summary judgment that all remaining asserted claims are invalid. The District Court granted that motion and, on August 23, 2019, entered judgment in our favor. On September 6, 2019, WaveForm appealed the judgment. The appeal is pending and no hearing date has been set.
We have also filed several lawsuits against AgaMatrix. We filed a patent infringement lawsuit against AgaMatrix in the United States District Court for the Central District of California, or C.D. Cal., in which a Final Judgment of non-infringement was entered by the C.D. Cal judge on February 23, 2018 and affirmed on appeal by the Federal Circuit on March 7, 2019. AgaMatrix was awarded attorneys’ fees for this lawsuit. As of December 31, 2019, we have accrued an immaterial amount for those fees. The fee decision is currently on appeal to the Federal Circuit. On September 15, 2017, we filed a patent infringement lawsuit against AgaMatrix in the United States District Court for the District of Delaware, asserting certain single-point blood glucose monitoring products of AgaMatrix infringe two patents held by us. In addition, on September 18, 2017, we filed a Complaint against AgaMatrix in the International Trade Commission, referred to as the ITC, requesting that the ITC institute an investigation and issue an order excluding certain products of AgaMatrix from importation into or sale in the United States based on AgaMatrix’s infringement of the same two patents asserted in the Delaware litigation. The investigation was terminated by the ITC on April 4, 2019 with a finding of non-infringement. The decision is currently on appeal.
Neither the outcome of these lawsuits nor the amount and range of potential loss associated with the lawsuits can be assessed at this time. Other than the attorneys’ fees described above, as of December 31, 2019 we have accrued no amounts for contingent losses associated with these suits.
We are subject to various claims, complaints and legal actions that arise from time to time in the normal course of business, including commercial insurance, product liability and employment related matters. In addition, from time to time we may bring claims or initiate lawsuits against various third parties with respect to matters arising out of the ordinary course of our business, including commercial and employment related matters. We do not believe we are party to any currently pending legal proceedings, the outcome of which could have a material adverse effect on our business, financial condition or results of operations. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on our business, financial condition or results of operations.

The statements of operations data for the years ended December 31, 2016 and 2015 and the consolidated balance sheet data as of December 31, 2017, 2016 and 2015 have been derived from our audited consolidated financial statements not included in this Annual Report. The following selected financial data should be read in conjunction with our “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7
ITEM 7 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This document, including the following Management’s Discussion and Analysis of Financial Condition and Results of Operations, contains forward-looking statements that are not purely historical regarding DexCom’s or its management’s intentions, beliefs, expectations and strategies for the future. These forward-looking statements fall within the meaning of the federal securities laws that relate to future events or our future financial performance. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “intend,” “potential” or “continue” or the negative of these terms or other comparable terminology. Forward-looking statements are made as of the date of this report, deal with future events, are subject to various risks and uncertainties, and actual results could differ materially from those anticipated in those forward looking statements. The risks and uncertainties that could cause actual results to differ materially are more fully described under “Risk Factors” and elsewhere in this report and in our other reports filed with the SEC. We assume no obligation to update any of the forward-looking statements after the date of this report or to conform these forward-looking statements to actual results. You should read the following discussion and analysis together with “Selected Financial Data” in Part II, Item 6 and our consolidated financial statements and related notes in Part II, Item 8 of this Annual Report.
We are a medical device company primarily focused on the design, development and commercialization of continuous glucose monitoring, or CGM, systems for use by people with diabetes and by healthcare providers. We received approval from the Food and Drug Administration, or FDA, and commercialized our first product in 2006. We launched our latest generation system, the DexCom G6® integrated Continuous Glucose Monitoring System, or G6, in 2018. Unless the context requires otherwise, the terms “we,” “us,” “our,” the “company,” or “DexCom” refer to DexCom, Inc. and its subsidiaries.
We sell our reusable transmitter and receiver, collectively referred to as “Reusable Hardware” and disposable sensors through a direct sales force in the United States, Canada and some countries in Europe, and through distribution arrangements in the United States, and certain countries in Africa, Asia, Europe, Latin America, and the Middle East, as well as Australia, Canada, and New Zealand. Most of our distributors stock our products and fulfill orders for our products from their inventory.
We plan to develop future generations of technologies that are focused on improved performance and convenience and that will enable intelligent insulin administration. We also are aggressively exploring how to extend our offerings to other opportunities, including for people with Type 2 diabetes that are non-insulin using, people with pre-diabetes, people who are obese, people who are pregnant, and people with diabetes in the hospital setting. We will continue to develop a networked platform with open architecture, connectivity and transmitters capable of communicating with other devices and software systems. We also intend to expand our efforts to accumulate CGM patient data and metrics and apply predictive modeling and machine learning to generate interactive CGM insights that can inform patient behavior.
For discussion related to the results of operations and changes in financial condition for fiscal 2018 compared to fiscal 2017 refer to Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our fiscal 2018 Form 10-K, which was filed with the United States Securities and Exchange Commission on February 21, 2019.
The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which we have prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements as well as the reported revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are more fully described in Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report, we believe that the following accounting policies and estimates are most critical to a full understanding and evaluation of our reported financial results. Members of our senior management have discussed the development and selection of these critical accounting policies and their disclosure in this Annual Report with the Audit Committee of our Board of Directors.
Revenue Recognition
We generate our revenue from the sale of our Reusable Hardware and disposable sensors. Disposable sensors are sold separately. We also provide free-of-charge software and mobile applications for use with our Reusable Hardware and disposable sensors. In determining how revenue should be recognized, a five-step process is used, which requires judgment and estimates within the revenue recognition process. The primary judgments include identifying the performance obligations in the contract and determining whether the performance obligations are distinct. We exercise significant judgment when we determine the transaction price, including variable consideration adjustments. If the actual amounts of consideration that we receive differ from our estimates, we would adjust our estimates and that would affect reported revenue in the period that such variances become known. If any of these judgments were to change it could cause a material increase or decrease in the amount of revenue we report in a particular period.
We generally recognize revenue when control is transferred to our customers in an amount that reflects the net consideration to which we expect to be entitled. Transaction price is typically based on the contracted rates less an estimate of claim denials and historical reimbursement experience by payor, which include current and future expectations regarding reimbursement rates and payor mix. We recognize revenue only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. We estimate reductions for rebates based on contractual arrangements, estimates of products sold subject to rebate, known events or trends and channel inventory data. For more information, see “Revenue Recognition” in Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report.
Disaggregation of Revenue.
We disaggregate revenue by geographic region and by major sales channel. We have determined that disaggregating revenue into these categories achieves the ASC Topic 606 disclosure objectives of depicting how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Reconciliations of revenue disaggregated by geographic location and by major sales channel to total revenue are provided in Note 10 to the consolidated financial statements in Part II, Item 8 of this Annual Report.
Share-Based Compensation
Share-based compensation expense is measured at the grant date based on the estimated fair value of the award and is recognized straight-line over the requisite service period of the individual grants, which typically equals the vesting period. We value time-based Restricted Stock Units (“RSUs”) at the date of grant using the intrinsic value method. Certain RSUs granted to senior management vest based on the achievement of pre-established performance or market goals.
We estimate the fair value of performance-based RSUs at the date of grant using the intrinsic value method and the probability that the specified performance criteria will be met. We update our assessment of the probability that the specified performance criteria will be achieved each quarter and adjust our estimate of the fair value of the performance-based RSUs if necessary. The Monte Carlo methodology that we use to estimate the fair value of market-based RSUs at the date of grant incorporates into the valuation the possibility that the market condition may not be satisfied. Provided that the requisite service is rendered, the total fair value of the market-based RSUs at the date of grant must be recognized as compensation expense even if the market condition is not achieved. However, the number of shares that ultimately vest can vary significantly with the performance of the specified market criteria.
If any of the assumptions used change significantly, share-based compensation expense may differ materially from what we have recorded in the current period.
Fair Value of Financial Instruments
The authoritative guidance establishes a fair value hierarchy that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. In general, the authoritative guidance requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the measurement of its fair value. The three levels of input defined by the authoritative guidance are as follows:
Level 1-Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities.
Level 2-Uses inputs other than quoted prices included in Level 1 that are observable, either directly or indirectly, through correlation with market data. These include quoted prices in active markets for similar assets or liabilities; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs to valuation models or other pricing methodologies that do not require significant judgment because the inputs used in the model, such as interest rates and volatility, can be corroborated by readily observable market data for substantially the full term of the assets or liabilities.
Level 3-Uses unobservable inputs that are supported by little or no market activity and that are significant to the determination of fair value. Level 3 assets and liabilities include those whose fair values are determined using pricing models, discounted cash flow methodologies, or similar valuation techniques and significant judgment or estimation.
We estimate the fair value of most of our cash equivalents using Level 1 inputs. We estimate the fair value of our marketable equity securities using Level 1 inputs and we estimate the fair value of our marketable debt securities using Level 2 inputs. We carry our other financial instruments, such as cash, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities, at cost, which approximates the related fair values due to the short-term maturities of these instruments. See Note 1 and Note 3 to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information about fair value measurements.
Accounts Receivable, Net and Related Valuation Accounts
We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We evaluate the collectability of our accounts receivable based on a combination of factors. We regularly analyze customer accounts, review the length of time receivables are outstanding, review historical loss rates and assess current economic trends that may impact the level of credit losses in the future. Our allowance for doubtful accounts has generally been adequate to cover our actual credit losses. However, since we cannot reliably predict future changes in the financial stability of our customers, we may need to increase our reserves if the financial conditions of our customers deteriorate.
Excess and Obsolete Inventory
Inventory is valued at the lower of cost or net realizable value. We record adjustments to inventory for potentially excess, obsolete, or scrapped goods in order to state inventory at net realizable value. Factors influencing these adjustments include inventories on hand and on order compared to estimated future usage and sales for existing and new products, as well as judgments regarding quality control testing data and assumptions about the likelihood of scrap and obsolescence. Historically, our inventory reserves have been adequate to cover our actual losses. However, if actual product life cycles, product quality or market conditions differ from our assumptions, additional inventory adjustments that would increase cost of goods sold could be required.
Income Taxes
We estimate our income taxes based on the various jurisdictions where we conduct business. Significant judgment is required in determining our worldwide income tax provision. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations and the potential for future adjustment of our uncertain tax positions by the Internal Revenue Service or other taxing jurisdictions. While we believe we have appropriate support for the positions taken on our tax returns, we regularly assess the potential outcomes of examinations by tax authorities in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the income tax provision, income taxes payable, and deferred taxes in the period in which the facts that give rise to a revision become known.
We use the asset and liability approach to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. Significant judgment is required to evaluate the need for a valuation allowance against deferred tax assets. We review all available positive and negative evidence, including projections of pre-tax book income, earnings history, and reliability of forecasting. A valuation allowance is established when it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2019, we have maintained a full valuation allowance on our deferred tax assets since inception based on our historical losses and the uncertainty of generating future taxable income to utilize our loss and credit carryforwards. A future release of our valuation allowance will result in a material tax benefit recognized in the quarter of the release.
We recognize and measure benefits for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not of being sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. Significant judgment is required to evaluate uncertain tax positions and is based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in our income tax expense in the period in which we make the change, which could have a material impact on our effective tax rate and operating results.
Loss Contingencies
We are subject to certain legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of our business. We review the status of each significant matter quarterly and assess our potential financial exposure. If the potential loss from a claim or legal proceeding is considered probable and the amount can be reasonably estimated, we record a liability and an expense for the estimated loss and disclose it in our consolidated financial statements if it is significant. If we determine that a loss is possible and the range of the loss can be reasonably determined, we do not record a liability or an expense but we disclose the range of the possible loss. Significant judgment is required in the determination of whether a potential loss is probable, reasonably possible, or remote as well as in the determination of whether a potential exposure is reasonably estimable. We base our judgments on the best information available at the time. As additional information becomes available, we reassess the potential liability related to our pending claims and litigation and may revise our estimates. Any revision of our estimates of potential liability could have a material impact on our financial position and operating results.
Financial Overview
* = Not Meaningful
Revenue, Cost of Sales and Gross Profit
We expect that revenues we generate from the sales of our products will fluctuate from quarter to quarter. We typically experience seasonality, with lower sales in the first quarter of each year compared to the immediately preceding fourth quarter. This seasonal sales pattern relates to U.S. annual insurance deductible resets and unfunded flexible spending accounts.
Cost of sales includes direct labor and materials costs related to each product sold or produced, including assembly, test labor and scrap, as well as factory overhead supporting our manufacturing operations. Factory overhead includes facilities, material procurement and control, manufacturing engineering, quality assurance, supervision and management. These costs are primarily salary, fringe benefits, share-based compensation, facility expense, supplies and purchased services. All of our manufacturing costs are included in cost of sales.
Fiscal 2019 Compared to Fiscal 2018
Total revenue increased $444.4 million or 43% for the twelve months ended December 31, 2019 compared to the twelve months ended December 31, 2018. The 2019 revenue increase was primarily driven by increased sales volume of our disposable sensors due to the continued growth of our worldwide customer base, partially offset by pricing pressure due to the evolution of our channel strategy and product mix. Disposable sensor and other revenue comprised approximately 78% of total revenue and Reusable Hardware revenue comprised approximately 22% of total revenue for the twelve months ended December 31, 2019. Disposable sensor and other revenue comprised approximately 75% of total revenue and Reusable Hardware revenue comprised approximately 25% of total revenue for the twelve months ended December 31, 2018.
Cost of sales increased $176.8 million or 48% for the twelve months ended December 31, 2019 compared to the twelve months ended December 31, 2018 primarily due to increased sales volume. The gross profit of $931.5 million or 63% of total revenue for the twelve months ended December 31, 2019 increased $267.6 million compared to $663.9 million or 64% of total revenue for the same period in 2018. The 2019 increase in gross profit dollars was primarily driven by increased revenues, partially offset by higher warranty, freight, and excess and obsolete inventory charges compared to 2018. The decrease in gross margin percentage is primarily a function of the evolution of our channel strategy and product mix as we launch new products and expand internationally. Our gross martin percentage for the twelve months ended December 31, 2019 was also impacted by investments to scale infrastructure as we drove significant production capacity expansion in 2019.
Operating Expenses
* = Not Meaningful
Our research and development expenses primarily consist of engineering and research expenses related to our continuous glucose monitoring technology, clinical trials, regulatory expenses, quality assurance programs, materials and products for clinical trials. Research and development expenses are primarily related to employee compensation, including salary, fringe
benefits, share-based compensation, and temporary employee expenses. We also incur significant expenses to operate our clinical trials including clinical site reimbursement, clinical trial product and associated travel expenses. Our research and development expenses also include fees for design services, contractors and development materials.
Our selling, general and administrative expenses primarily consist of salary, fringe benefits and share-based compensation for our executive, financial, sales, marketing, information technology and administrative functions. Other significant expenses include commissions, marketing and advertising, IT software license costs, insurance, professional fees for our outside legal counsel and independent auditors, litigation expenses, patent application expenses and consulting expenses.
Fiscal 2019 Compared to Fiscal 2018
Research and Development Expense. Research and development expense increased $73.8 million or 37% for the twelve months ended December 31, 2019 compared to the same period of 2018. The increase was primarily due to $39.7 million in additional salaries, bonus, and payroll-related costs, $11.1 million in additional supplies costs, and $7.3 million in additional facilities costs. We continue to believe that focused investments in research and development are critical to our future growth and competitive position in the marketplace, and to the development of new and updated products and services that are central to our core business strategy.
Collaborative Research and Development Fee. Collaborative research and development fee decreased $217.7 million for the twelve months ended December 31, 2019 compared to the same period of 2018. During 2018, we recorded a one time $217.7 million collaborative research and development charge related to our collaboration and license agreement with Verily. See Note 2 to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information about this collaboration agreement.
Selling, General and Administrative Expense. Selling, general and administrative expense increased $82.9 million or 19% for the twelve months ended December 31, 2019 compared to the same period of 2018. The increase was primarily due to higher sales-related costs commensurate with revenue growth and the continued commercialization of our products in the United States and international markets. Significant elements of the increase in selling, general, and administrative expenses included $20.5 million in additional third party service provider fees, $13.1 million in additional salaries, bonus and payroll-related costs, $11.0 million in additional consulting fees, $9.3 million in additional marketing costs, $8.6 million in additional depreciation, and $7.5 million in restructuring charges.
Non-Operating Income and Expenses
Interest Expense
Interest expense increased $37.6 million to $60.3 million for the twelve months ended December 31, 2019 compared to $22.7 million for the same period of 2018. The increase was primarily due to an additional interest expense for our 2023 Notes, which were issued in November 2018.
Income/Loss from Equity Investments
Loss from equity investments of $4.2 million for the twelve months ended December 31, 2019 and income from equity investments of $80.1 million for the twelve months ended months ended December 31, 2018 consist solely of realized and unrealized gains and losses on our equity investment in Tandem Diabetes Care, Inc. We sold all of our remaining equity investment in Tandem during the first quarter of 2019.
Interest and Other Income (Expense), Net
Interest income was $28.4 million and $10.5 million for the twelve months ended December 31, 2019 and 2018, respectively, and is related to our marketable debt securities portfolio. The increase in interest income was primarily related to an increase in the average invested balances during 2019 compared to 2018.
Other income (expense) for the twelve months ended December 31, 2019 and 2018 consists primarily of foreign currency transaction gains and losses due to the effects of foreign currency fluctuations.
Income Tax Expense
We recorded pre-tax income for the twelve months ended December 31, 2019, and pre-tax loss for the twelve months ended December 31, 2018. The income tax expense we recorded for 2019 is primarily attributable to state and foreign income tax expense. The nominal income tax expense we recorded for 2018 is primarily due to withholding and other income tax expenses in profitable jurisdictions.
Overview, Capital Resources, and Capital Requirements
Our principal sources of liquidity are our existing cash, cash equivalents and marketable securities, cash generated from operations, proceeds from our convertible notes issuances, and access to our revolving line of credit. Our primary uses of cash have been for research and development programs, selling and marketing activities, capital expenditures, acquisitions of businesses, and debt service costs.
We expect that cash provided by our operations may fluctuate in future periods as a result of a number of factors, including fluctuations in our operating results, working capital requirements and capital deployment decisions. We have historically invested our cash primarily in U.S. dollar-denominated, investment grade, highly liquid obligations of U.S. government-sponsored enterprises, commercial paper, corporate debt, and money market funds. Certain of these investments are subject to general credit, liquidity and other market risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets.
Our future capital requirements will depend on many factors, including but not limited to:
•
the revenue generated by sales of our approved products and other future products;
•
the expenses we incur in manufacturing, developing, selling and marketing our products;
•
the quality levels of our products and services;
•
the third-party reimbursement of our products for our customers;
•
our ability to efficiently scale our operations to meet demand for our current and any future products;
•
the costs, timing and risks of delays of additional regulatory approvals;
•
the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
•
the rate of progress and cost of our clinical trials and other development activities;
•
the success of our research and development efforts;
•
the emergence of competing or complementary technological developments;
•
the terms and timing of any collaborative, licensing and other arrangements that we may establish;
•
the acquisition of businesses, products and technologies and our ability to integrate and manage any acquired businesses, products and technologies; and
•
the evolution of the international expansion of our business.
We expect that existing cash and cash flows from our future operations will generally be sufficient to fund our ongoing core business. As current borrowing sources become due, we may be required to access the capital markets for additional funding. As we assess inorganic growth strategies, we may need to supplement our internally generated cash flow with outside sources. In the event that we are required to access the debt market, we believe that we will be able to secure reasonable borrowing rates. As part of our liquidity strategy, we will continue to monitor our current level of earnings and cash flow generation as well as our ability to access the market in light of those earning levels.
A substantial portion of our operations are located in the United States, and the majority of our sales since inception have been made in U.S. dollars. Accordingly, our assessment is that we have no material net exposure to foreign currency exchange rate fluctuations at this time. However, as our business in markets outside of the United States continues to increase, we will be exposed to foreign currency exchange risk related to our foreign operations. Fluctuations in the rate of exchange between the U.S. dollar and foreign currencies, primarily the British Pound, the Euro, and the Canadian Dollar, could adversely affect our financial results, including our revenues, revenue growth rates, gross margins, income and losses as well as assets and liabilities. We currently engage in limited hedging transactions to reduce foreign currency risks on certain intercompany balances. We will continue to monitor and manage our financial exposures due to exchange rate fluctuations as an integral part of our overall risk management program. Our cash, cash equivalents and short-term marketable securities totaled $1,533.3 million as of December 31, 2019. None of those funds were restricted and approximately 98% of those funds were located in the United States. We intend to reinvest a substantial portion of our foreign earnings in those businesses, and we currently do not anticipate that we will need funds generated by foreign operations to fund our domestic ones.
Our cash, cash equivalents and short-term marketable securities as of December 31, 2019 increased by $147.7 million from December 31, 2018 due to the factors described in “Cash Flows” below. We believe that our cash, cash equivalents, and marketable securities balances, projected cash contributions from our commercial operations, and our $200.0 million revolving line of credit, of which $195.6 million remains available, will be sufficient to meet our anticipated seasonal working capital
needs, capital expenditure requirements, contractual obligations, commitments, debt service requirements, and other liquidity requirements associated with our operations for at least the next 12 months.
Revolving Credit Agreement
In December 2018, we entered into an amended and restated five-year $200.0 million revolving Credit Agreement, including a sub-facility of up to $10.0 million for letters of credit. Subject to customary conditions and the approval of any lender whose commitment would be increased, we have the option to increase the maximum principal amount available under the Credit Agreement by up to an additional $300.0 million, resulting in a maximum available principal amount of $500.0 million. However, at this time none of the lenders have committed to provide any such increase in their commitments. Revolving loans under the Credit Agreement will be available for general corporate purposes, including working capital and capital expenditures. As of December 31, 2019, we had no outstanding borrowings, $4.4 million in outstanding letters of credit, and a total available balance of $195.6 million under the Credit Agreement. We monitor counterparty risk associated with the institutional lenders that are providing the credit facility. We currently believe that the credit facility will be available to us should we choose to borrow under it.
Senior Convertible Notes
The following table summarizes our outstanding convertible note obligations:
We used a portion of the net proceeds from the offering of the Notes due 2022 (the 2022 Notes) to repay $75.0 million of borrowings under our existing credit facility in 2017. We used a portion of the net proceeds from the offering of the Notes due 2023 (the 2023 Notes) to repurchase 0.8 million shares of our common stock for $100.0 million in 2018. The remainder of the net proceeds from the Notes offerings are available for general corporate purposes and capital expenditures, including working capital needs. We may also use the net proceeds to expand our current business through in-licensing or acquisitions of, or investments in, other businesses, products or technologies; however, we do not have any significant commitments with respect to any such acquisitions or investments at this time.
2023 Note Hedge
In connection with the offering of the 2023 Notes, in November 2018 we entered into convertible note hedge transactions (the 2023 Note Hedge) with two of the initial purchasers of the 2023 Notes (the 2023 Counterparties) entitling us to purchase up to 5.2 million shares of our common stock at an initial price of $164.29 per share, each of which is subject to adjustment. The cost of the 2023 Note Hedge was $218.9 million and it will expire on December 1, 2023. The 2023 Note Hedge is expected to reduce the potential equity dilution upon any conversion of the 2023 Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted 2023 Notes if the daily volume-weighted average price per share of our common stock exceeds the strike price of the 2023 Note Hedge. The strike price of the 2023 Note Hedge initially corresponds to the conversion price of the 2023 Notes and is subject to certain adjustments under the terms of the 2023 Note Hedge.
2023 Warrants
In November 2018, we also sold warrants (the 2023 Warrants) to the 2023 Counterparties to acquire up to 5.2 million shares of our common stock for cash proceeds of $183.8 million. The 2023 Warrants require net share settlement and a pro-rated number of warrants will expire on each of the 60 scheduled trading days starting on March 1, 2024.
See Note 5 to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information about the terms of the Credit Agreement, 2022 Notes and the 2023 Notes, the 2023 Note Hedge, and the 2023 Warrants.
Cash Flows
The following table sets forth a summary of our cash flows for the periods indicated. See the consolidated financial statements in Part II, Item 8 of this Annual Report for complete statements of cash flows for these periods.
As of December 31, 2019, we had $1,533.3 million in cash, cash equivalents and short-term marketable securities, which is an increase of $147.7 million compared to $1,385.6 million as of December 31, 2018. The primary cash flows during the twelve months ended December 31, 2019 and 2018 are described below.
Operating Cash Flows
Net cash provided by operating activities during 2019 was comprised of net income of $101.1 million, net adjustments of $207.3 million and $6.1 million of changes in working capital balances. Net adjustments were primarily related to share-based compensation, depreciation and amortization, non-cash interest expense for our senior convertible notes, and a loss on the sale of our remaining equity investment in Tandem Diabetes Care, Inc.
Net cash provided by operating activities during 2018 was comprised of a net loss of $127.1 million, offset by $291.2 million of net adjustments and $40.9 million of changes in working capital balances. Net adjustments were primarily related to share-based compensation, depreciation and amortization, and non-cash interest expense for our senior convertible notes, and realized and unrealized gains on our equity investment in Tandem Diabetes Care, Inc.
Investing Cash Flows
Net cash used in investing activities during 2019 was primarily comprised of $835.2 million for net purchases of marketable securities and other equity investments and $180.0 million for capital expenditures.
Net cash used in investing activities during 2018 was primarily comprised of $61.4 million for net purchases of marketable securities and other equity investments and $67.1 million for capital expenditures.
Financing Cash Flows
Net cash provided by financing activities during 2019 was primarily comprised of $11.9 million in proceeds from the issuance of common stock under our employee stock plans.
Net cash provided by financing activities during 2018 was primarily comprised of $836.6 million in net proceeds from the issuance of our 2023 Notes and $183.8 million in proceeds from the sale of the 2023 Warrants, partially offset by $218.9 million for the purchase of the 2023 Note Hedge and $100.0 million to purchase shares of our common stock.
Contractual Obligations
We are party to various leasing arrangements, primarily for office, manufacturing and warehouse space that expire at various times through March 2028.
The following table summarizes our outstanding contractual obligations as of December 31, 2019 and the effect those obligations are expected to have on our liquidity and cash flows in future periods:
(1)
We issued senior convertible notes in May and June 2017 that are due in May 2022 and we issued senior convertible notes in November 2018 that are due in December 2023. The obligations presented above include both principal and interest for these notes. Although these notes mature in 2022 and 2023, they may be converted into cash and shares of
our common stock prior to maturity if certain conditions are met. Any conversion prior to maturity can result in repayment of the principal amounts sooner than the scheduled repayment as indicated in the table. See Note 5 to the consolidated financial statements in Part II, Item 8 of this Annual Report for further discussion of the terms of our senior convertible notes.
(2)
Includes a finance lease obligation related to our Mesa, Arizona facility. See Note 6 to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information.
We are also party to various purchase arrangements related to components used in manufacturing and research and development activities. As of December 31, 2019, we had approximately $165.8 million of open purchase orders and contractual obligations in the ordinary course of business, most of which are due within one year.
Off-Balance Sheet Arrangements
As of December 31, 2019, we did not have any significant off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K.
For a description of recently issued accounting guidance that is applicable to our financial statements, see Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report.
ITEM 7A
ITEM 7A - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and short-term investments in a variety of securities, including money market funds, U.S. Treasury debt and corporate debt securities. Due to the short-term nature of our investments, we believe that we have no material exposure to interest rate risk.
Market Price Sensitive Instruments
In order to reduce potential equity dilution, in connection with the issuance of the 2023 Notes we entered into the 2023 Hedge which entitles us to purchase shares of our common stock. Upon conversion of the 2023 Notes, the 2023 Hedge is expected to reduce the equity dilution if the daily volume-weighted average price per share of our common stock exceeds the strike price of the hedge. We also entered into warrant transactions with the counterparties of the 2023 Hedge entitling them to acquire shares of our common stock. The warrant transactions could have a dilutive effect on our earnings per share to the extent that the price of our common stock during a given quarterly or annual measurement period exceeds the strike price of the warrants. See Note 5 to the consolidated financial statements in Part II, Item 8

Not applicable.
ITEM 9A
ITEM 9A - CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Regulations under the Securities Exchange Act of 1934 require public companies to maintain “disclosure controls and procedures,” which are defined to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and timely communicated to management, including our Chief Executive Officer and Chief Financial Officer, recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Our management, including our Chief Executive Officer and our Chief Financial Officer, conducted an evaluation as of the end of the period covered by this report of the effectiveness of our disclosure controls and procedures. Based on their evaluation as of December 31, 2019, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of such date for this purpose.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements.
Our management, with the participation of the Chief Executive and Chief Financial Officers, assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, our management used the criteria set forth by the 2013 Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on this assessment, our management, with the participation of the Chief Executive and Chief Financial Officers, believes that, as of December 31, 2019, our internal control over financial reporting is effective based on those criteria. The effectiveness of our internal control over financial reporting as of December 31, 2019 has been audited by Ernst & Young LLP an Independent Registered Public Accounting Firm, as stated in their report which is included herein.
The certifications of our Chief Executive Officer and Chief Financial Officer required under Section 302 of the Sarbanes-Oxley Act have been filed as Exhibits 31.01 and 31.02 to this report.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.
Limitation on Effectiveness of Controls
It should be noted that any system of controls, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system are met. The design of any control system is based, in part, upon the benefits of the control system relative to its costs. Control systems can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. In addition, over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of these and other inherent limitations of control systems, we cannot guaranty that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of DexCom, Inc.
Opinion on Internal Control over Financial Reporting
We have audited DexCom, Inc.’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the COSO criteria). In our opinion, DexCom, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of DexCom, Inc. as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2019, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 13, 2020 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the consolidated financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of DexCom, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of DexCom, Inc. (the Company) as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2019, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) and our report dated February 13, 2020 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Estimation of transaction price and variable consideration for revenue recognition
Description of the Matter
As discussed in Note 1 of the consolidated financial statements, the Company recognizes revenue from contracted insurance payors and distributors based on a transaction price which reflects the net consideration to which the Company expects to be entitled. The transaction price is typically based on the contracted rates less an estimate of claim denials and historical reimbursement experience by payor, which include current and future expectations regarding reimbursement rates and payor mix. The Company estimates reductions for rebates based on contractual arrangements, estimates of products sold subject to rebate, known events or trends and channel inventory data.
Auditing management’s determination of transaction price including variable consideration involved a high degree of subjectivity in evaluating management’s estimates. In determining transaction price, management develops estimates based on actual historical reimbursement experience by payor. In estimating variable consideration related to rebates, management applies contracted rates to estimates of products sold subject to rebate, known events or trends and channel inventory data.
How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s processes to determine transaction price and variable consideration, including the underlying assumptions.
Our audit procedures also included, among others, evaluating the significant assumptions and the accuracy and completeness of the underlying data used in management’s calculations. For transaction price, this included testing management’s estimate of the claim denials and historical reimbursement experience through a combination of underlying data validation by inspection of source documents and independent recalculation of management’s analysis. For rebates, this included testing contractual rates, management’s estimates of products sold subject to rebate, and inventory held by distributors at the end of the period, through a combination of underlying data validation by inspection of source documents, agreement to underlying contracts, review for consistency against historical data, and trending of inventory held at distributors versus inventory sold into the channel. In addition, we inspected the results of the Company’s retrospective review analysis of rebates claimed, evaluated the estimates made based on historical experience and performed sensitivity analyses over the Company's significant assumptions.

Organization and Business
DexCom, Inc. is a medical device company focused on the design, development and commercialization of CGM system(s) for use by people with diabetes and by healthcare providers. Unless the context requires otherwise, the terms “we,” “us,” “our,” the “company,” or “DexCom” refer to DexCom, Inc. and its subsidiaries.
Basis of Presentation and Principles of Consolidation
The consolidated financial statements include the accounts of DexCom, Inc. and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. We have reclassified certain amounts previously reported in our financial statements to conform to the current presentation.
The functional currencies of our international subsidiaries are generally the local currencies. We translate the financial statements of our foreign subsidiaries into U.S. dollars using period-end exchange rates for assets and liabilities and average exchange rates for each period for revenue, costs and expenses. We include translation-related adjustments in comprehensive income (loss) and in accumulated other comprehensive income in the equity section of our consolidated balance sheet. Gains and losses resulting from certain intercompany transactions as well as transactions with customers and vendors that are denominated in currencies other than the functional currency of each entity give rise to foreign exchange gains or losses that we record in interest and other income, net in our consolidated statements of operations.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires us to make certain estimates and assumptions that affect the amounts reported in our financial statements and the disclosures made in the accompanying notes. Areas requiring significant estimates include pharmacy rebates, transaction price, net accounts receivable, excess or obsolete inventories and the valuation of inventory, and accruals for litigation contingencies. Despite our intention to establish accurate estimates and use reasonable assumptions, actual results may differ from our estimates.
Fair Value Measurements
The authoritative guidance establishes a fair value hierarchy that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. In general, the authoritative guidance requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the measurement of its fair value. The three levels of input defined by the authoritative guidance are as follows:
Level 1-Unadjusted quoted prices that are available in active markets for identical assets or liabilities.
Level 2-Inputs other than quoted prices included in Level 1 that are observable, either directly or indirectly, through correlation with market data. These include quoted prices in active markets for similar assets or liabilities; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs to valuation models or other pricing methodologies that do not require significant judgment because the inputs used in the model, such as interest rates and volatility, can be corroborated by readily observable market data for substantially the full term of the assets or liabilities.
Level 3-Unobservable inputs that are supported by little or no market activity and that are significant to the determination of fair value. Level 3 assets and liabilities include those whose fair values are determined using pricing models, discounted cash flow methodologies, or similar valuation techniques and significant judgment or estimation.
We carry our marketable securities at fair value. We carry our other financial instruments, such as cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities, at cost, which approximates the related fair values due to the short-term maturities of these instruments. For more information see Note 3, “Fair Value Measurements.”
Cash and Cash Equivalents
We consider highly liquid investments with a maturity of 90 days or less at the time of purchase to be cash equivalents.
Marketable Securities
We have classified our marketable securities with remaining maturity at purchase of more than three months and remaining maturities of one year or less as short-term marketable securities. We have also classified marketable securities with remaining maturities of greater than one year as short-term marketable securities based upon our ability and intent to use any and all of those marketable securities to satisfy the liquidity needs of our current operations.
We calculate realized gains or losses on our marketable securities using the specific identification method. We carry our marketable debt securities at fair value with unrealized gains and losses reported as a separate component of stockholders’ equity in our consolidated balance sheets and included in comprehensive income (loss). Realized gains and losses on marketable debt securities are included in interest and other income, net in our consolidated statements of operations. We carry our marketable equity securities at fair value with realized and unrealized gains and losses reported in income on equity investments in our consolidated statements of operations.
We invest in various types of debt securities, including debt securities in government-sponsored entities, corporate debt securities, U.S. Treasury securities and commercial paper. We do not generally intend to sell these investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity. See Note 3, “Fair Value Measurements” and Note 4, “Balance Sheet Details - Short-Term Marketable Securities” for more information on our marketable debt securities and our marketable equity securities.
Accounts Receivable and Allowance for Doubtful Accounts
Accounts receivable are generally recorded at the invoiced amount for Distributors and at net realizable value for Direct customers, which is determined using estimates of claim denials and historical reimbursement experience without regard to aging category. Accounts receivable are not interest bearing. We evaluate the creditworthiness of significant customers and generally do not require collateral from our customers. We maintain an allowance for doubtful accounts for potential credit losses. Uncollectable accounts are written off against the allowance after appropriate collection efforts have been exhausted and when it is deemed that a customer account is uncollectable. Generally, receivable balances greater than one year past due are deemed uncollectable.
Concentration of Credit Risk and Significant Customers
Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash, cash equivalents, short-term marketable securities, and accounts receivable. We limit our exposure to credit risk by placing our cash and investments with high credit quality financial institutions. We have also established guidelines regarding diversification of our investments and their maturities that are designed to maintain principal and maximize liquidity. We review these guidelines periodically and modify them to take advantage of trends in yields and interest rates and changes in our operations and financial position.
The following table sets forth the percentages of total revenue or gross accounts receivable for customers that represent 10% or more of the respective amounts for the periods shown:
* Less than 10%
Inventory
Inventory is valued at the lower of cost or net realizable value on a part-by-part basis that approximates first in, first out. We record adjustments to inventory for potentially excess, obsolete or scrapped goods in order to state inventory at net realizable value. Factors influencing these adjustments include inventories on hand and on order compared to estimated future usage and sales for existing and new products, as well as judgments regarding quality control testing data and assumptions about the likelihood of scrap and obsolescence. Once written down the adjustments are considered permanent and are not reversed until the related inventory is sold or disposed of.
Our products require customized products and components that currently are available from a limited number of sources. We purchase certain components and materials from single sources due to quality considerations, costs or constraints resulting from regulatory requirements.
Property and Equipment
Property and equipment is stated at cost less accumulated depreciation. We calculate depreciation using the straight-line method over the estimated useful lives of the assets. Estimated useful lives are generally three years for computer software and hardware, four to fifteen years for machinery and equipment, and five years for furniture and fixtures. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the remaining lease term. We include the amortization of assets that are recorded under finance leases in depreciation expense.
We review property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We estimate the recoverability of the asset by comparing the carrying amount to the future undiscounted cash flows that we expect the asset to generate. We estimate the fair value of the asset based on the present value of future cash flows for those assets. If the carrying value of an asset exceeds its estimated fair value, we would record an impairment loss equal to the difference.
Goodwill
We record goodwill when the fair value of consideration transferred in a business combination exceeds the fair value of the identifiable assets acquired and liabilities assumed. Goodwill and other intangible assets that have indefinite useful lives are not amortized, but we test them annually for impairment in the fourth quarter of our fiscal year and whenever events or changes in circumstances indicate that it is more likely than not that the fair value is less than the carrying value. Events that would indicate impairment and trigger an interim impairment assessment include, but are not limited to, current economic and market conditions, including a decline in market capitalization, a significant adverse change in legal factors, business climate or operational performance of the business, and an adverse action or assessment by a regulator.
We perform our goodwill impairment analysis at the reporting unit level, which aligns with DexCom’s reporting structure and the availability of discrete financial information. We perform the first step of our annual impairment analysis by either comparing a reporting unit’s estimated fair value to its carrying amount or doing a qualitative assessment of a reporting unit’s fair value from the last quantitative assessment to determine if there is potential impairment. We may do a qualitative assessment when the results of the previous quantitative test indicated the reporting unit’s estimated fair value was significantly in excess of the carrying value of its net assets and we do not believe there have been significant changes in the reporting unit’s operations that would significantly decrease its estimated fair value or significantly increase its net assets. If a quantitative assessment is performed the evaluation includes management estimates of cash flow projections based on internal future projections and/or use of a market approach by looking at market values of comparable companies. Key assumptions for these projections include revenue growth, future gross margin and operating margin growth, and weighted cost of capital and terminal growth rates. The revenue and margin growth are based on increased sales of new and existing products as we maintain investments in research and development. Additional assumed value creators may include increased efficiencies from capital spending. The resulting cash flows are discounted using a weighted average cost of capital. Operating mechanisms and requirements to ensure that growth and efficiency assumptions will ultimately be realized are also considered in the evaluation, including the timing and probability of regulatory approvals for our products to be commercialized. We also consider DexCom’s market capitalization as a part of our analysis.
If the estimated fair value of a reporting unit exceeds the carrying amount of the net assets assigned to that unit, goodwill is not impaired and no further analysis is required. If the carrying value of the net assets assigned to a reporting unit exceeds the estimated fair value of the unit, we perform the second step of the impairment test. In this step we allocate the fair value of the reporting unit calculated in step one to all of the assets and liabilities of that unit, as if we had just acquired the reporting unit in a business combination. The excess of the fair value of the reporting unit over the total amount allocated to the assets and liabilities represents the implied fair value of goodwill. If the carrying amount of a reporting unit’s goodwill exceeds its implied fair value, we would record an impairment loss equal to the difference. We recorded no goodwill impairment charges for the twelve months ended December 31, 2019, 2018 or 2017.
The change in goodwill for the twelve months ended December 31, 2017 and December 31, 2019 consisted of translation adjustments on our foreign currency denominated goodwill. The change in goodwill for the twelve months ended December 31, 2018 consisted of goodwill we recorded for acquisitions that were not significant, individually or in the aggregate, and translation adjustments on our foreign currency denominated goodwill.
Intangible Assets and Other Long-Lived Assets
We amortize intangible assets with a finite life, such as acquired technology, customer relationships, trade names and trademarks, on a straight-line basis over their estimated useful lives, which range from two to five years. We review intangible assets that have finite lives and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We estimate the fair value of the asset based on the present value of future cash flows for those assets. If the carrying value of an asset exceeds its estimated fair value, we would record an impairment loss equal to the difference.
Income Taxes
We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized, which requires significant judgment. The realization of deferred tax assets is dependent, in part, upon future taxable income. In assessing whether our deferred tax assets will be realized, we consider all available evidence, both positive and negative. Such evidence includes historical earnings, future reversals of existing taxable temporary differences, estimates of future taxable income, and the feasibility of ongoing tax planning strategies. We have recorded a full valuation allowance on our net deferred tax asset balances for all periods presented because of the uncertainty related to utilization of our deferred tax assets.
We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.
We file federal and state income tax returns in the United States and income tax returns in various other foreign jurisdictions with varying statutes of limitations. Due to net operating losses incurred, our income tax returns from inception to date are subject to examination by taxing authorities. We recognize interest expense and penalties related to income tax matters, including unrecognized tax benefits, as a component of income tax expense.
Warranty Accrual
Estimated warranty costs associated with a product are recorded at the time revenue is recognized. We estimate future warranty costs by analyzing historical warranty experience for the timing and amount of returned product, and expectations for future warranty activity based on changes and improvements to the product or process that are in place or will be in place in the future. We evaluate these estimates on at least a quarterly basis to determine the continued appropriateness of our assumptions.
Loss Contingencies
If the potential loss from a claim or legal proceeding is considered probable and the amount can be reasonably estimated, we record a liability and an expense for the estimated loss and disclose it in our financial statements if it is significant. If we determine that a loss is possible and the range of the loss can be reasonably determined, then we disclose the range of the possible loss. Significant judgment is required in the determination of whether a potential loss is probable, reasonably possible, or remote as well as in the determination of whether a potential exposure is reasonably estimable.
Comprehensive Income (Loss)
Comprehensive income (loss) consists of two elements, net income (loss) and other comprehensive income (loss). We report all components of comprehensive income (loss), including net income (loss), in our financial statements in the period in which they are recognized. Total comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. We report net income (loss) and the components of other comprehensive income (loss), including foreign currency translation adjustments and unrealized gains and losses on marketable securities, net of their related tax effect to arrive at total comprehensive income (loss).
Revenue Recognition
We generate our revenue from the sale of our Reusable Hardware and disposable sensors, which we refer to in this section as “Components”.
We adopted ASC Topic 606 effective January 1, 2018 using the modified retrospective method. Our revenue recognition policies under ASC Topic 606 are explained below.
Policy elections and practical expedients taken
•
We report revenue net of taxes collected from customers, which are subsequently remitted to governmental authorities;
•
We account for shipping and handling activities that are performed after a customer has obtained control of a good as fulfillment costs rather than as separate performance obligations;
•
We do not assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer; and
•
If we expect, at contract inception, that the period between the transfer of control and corresponding payment from the customer will be one year or less, we do not adjust the amount of consideration for the effects of a significant financing component.
Contracts and performance obligations
We consider customer purchase orders, which in most cases are governed by agreements with distributors or third-party payors, to be contracts with a customer. For each contract, we consider the obligation to transfer Components to the customer, each of which are distinct, to be separate performance obligations. We also provide free-of-charge software, mobile applications and updates for our DexCom Share® remote monitoring system. The standalone selling prices of our free-of-charge software, mobile applications and updates are estimated based on an expected cost plus a margin approach.
Transaction price
Transaction price for the Components reflects the net consideration to which we expect to be entitled. Transaction price is typically based on the contracted rates less an estimate of claim denials and historical reimbursement experience by payor, which include current and future expectations regarding reimbursement rates and payor mix.
Variable consideration
Rebates. We estimate reductions for rebates based on contractual arrangements, estimates of products sold subject to rebate, known events or trends and channel inventory data.
Product Returns. In accordance with the terms of their distribution agreements, most distributors do not have rights of return outside of our limited warranty. The distributors typically have a limited time frame to notify us of any missing, damaged, defective or non-conforming products. We generally provide a “30-day money back guarantee” program whereby first-time end-user customers may return Reusable Hardware. Product returns have historically been immaterial.
Revenue recognition
The timing of revenue recognition is based on the satisfaction of performance obligations. Substantially all of the performance obligations associated with our Components are satisfied at a point in time, which typically occurs at shipment of our products. Terms of direct and distributor orders are generally Freight on Board (FOB) shipping point for U.S. orders or Free Carrier (FCA) shipping point for international orders. For certain of our distributors, control transfers at delivery of the product to the customer.
In cases where our free-of-charge software, mobile applications and updates are deemed to be separate performance obligations, revenue is recognized over time on a ratable basis over the estimated life of the related hardware component.
Our sales of Components include an assurance-type warranty.
Judgments and Estimates
In determining how revenue should be recognized, a five-step process is used, which requires judgment and estimates that can have a significant impact on the amount and timing of revenue we report. These judgments and estimates include identifying performance obligations in the contract, determining whether the performance obligations are separate, allocating the transaction price to each separate performance obligation, determining the timing of revenue recognition for separate performance obligations and estimating the amount of variable consideration to include in the transaction price.
Contract balances
Contract balances represent amounts presented in the consolidated balance sheets when either we have transferred goods or services to the customer or the customer has paid consideration to us under the contract. These contract balances include accounts receivable and deferred revenue. Payment terms vary by contract type and type of customer and generally range from 30 to 90 days.
Accounts receivable as of December 31, 2019 included unbilled accounts receivable of $3.6 million. Unbilled accounts receivable consists of revenue recognized for Components we have delivered but not yet invoiced to customers. We expect to invoice and collect all unbilled accounts receivable within twelve months.
We record deferred revenue when we have entered into a contract with a customer and cash payments are received or due prior to transfer of control or satisfaction of the related performance obligation. The table below shows revenue that we recognized as a result of changes in the contract liability balances in the periods shown.
Our performance obligations are generally satisfied within 12 months of the initial contract date. As of December 31, 2019, the deferred revenue balance related to performance obligations that will be satisfied after 12 months was $2.1 million. and is included in other long-term liabilities on our consolidated balance sheets. As of December 31, 2018, we had no deferred revenue balance related to performance obligations that will be satisfied after 12 months.
Deferred cost of sales
Deferred cost of sales are associated with sales for which revenue recognition criteria are not met but product has shipped and released from inventory. Deferred cost of sales are included in prepaid and other current assets in our consolidated balance sheets.
Incentive compensation costs
We generally expense incentive compensation associated with our internal sales force when incurred because the amortization period for such costs, if capitalized, would have been one year or less. We record these costs in selling, general and administrative expense in our consolidated statement of operations.
Product Shipment Costs
We record the amounts we charge our customers for the shipping and handling of our products in revenue and we record the related costs as cost of sales in our statements of operations.
Research and Development
We expense costs of research and development as we incur them. Our research and development expenses primarily consist of engineering and research expenses related to our continuous glucose monitoring technology, clinical trials, regulatory expenses, quality assurance programs, materials and products for clinical trials. Research and development expenses primarily consist of employee compensation, including salary, fringe benefits, share-based compensation, and temporary employee expenses. We also incur significant expenses to operate our clinical trials that include clinical site reimbursement, clinical trial product, and associated travel expenses. Our research and development expenses also include fees for design services, contractors, and development materials.
Our CGM systems include certain software that we develop. We expense software development costs as we incur them until technological feasibility has been established, at which time we capitalize development costs until the product is available for general release to customers. To date, our software has been available for general release concurrent with the establishment of technological feasibility and, accordingly, we have not capitalized any development costs.
Advertising Costs
We expense advertising costs as we incur them to selling, general and administrative expenses. Advertising expense was $31.8 million, $25.4 million and $21.9 million for the twelve months ended December 31, 2019, 2018 and 2017, respectively.
Leases
We determine if an arrangement is a lease at inception. Lease right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The interest rate used to determine the present value of the future lease payments is our incremental borrowing rate, because the interest rate implicit in most of our leases is not readily determinable. Our incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in similar economic environments. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease payments that do not depend on a rate or index, payments associated with non-lease components, and costs related to leases with terms of less than 12 months are expensed as incurred.
Share-Based Compensation
Share-based compensation expense is measured at the grant date based on the estimated fair value of the award and is recognized straight-line over the requisite service period of the individual grants, which typically equals the vesting period.
We value time-based Restricted Stock Units (“RSUs”) at the date of grant using the intrinsic value method. Certain RSUs granted to senior management vest based on the achievement of pre-established performance or market goals.
We estimate the fair value of performance/market-based RSUs at the date of grant using the intrinsic value method and the probability that the specified performance criteria will be met. We update our assessment of the probability that the specified performance criteria will be achieved each quarter and adjust our estimate of the fair value of the performance-based RSUs if necessary. The Monte Carlo methodology that we use to estimate the fair value of market-based RSUs at the date of grant incorporates into the valuation the possibility that the market condition may not be satisfied. Provided that the requisite service is rendered, the total fair value of the market-based RSUs at the date of grant must be recognized as compensation expense even if the market condition is not achieved. However, the number of shares that ultimately vest can vary significantly with the performance of the specified market criteria.
If any of the assumptions used change significantly, share-based compensation expense may differ materially from what we have recorded in the current period.
We account for forfeitures as they occur by reversing any share-based compensation expense related to awards that will not vest.
Net Income (Loss) Per Share
Basic net income (loss) per share attributable to common stockholders is calculated by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares outstanding during the period and, when dilutive, potential common share equivalents.
Potentially dilutive common shares consist of shares issuable from stock options, unvested RSUs, warrants and the 2022 and 2023 Senior Convertible Notes. Potentially dilutive common share equivalents shares from outstanding stock options, warrants and unvested RSUs are determined using the average share price for each period under the treasury stock method. Potentially dilutive shares issuable upon conversion of our 2022 and 2023 Senior Convertible Notes are determined using the if-converted method.
The following table sets forth the computation of basic and diluted net income (loss) per share for the periods shown.
In periods of net losses, we exclude potentially dilutive common shares from the computation of the diluted net loss per share for those periods as the effect would be anti-dilutive.
Outstanding anti-dilutive securities not included in the diluted net income (loss) per share attributable to common stockholders calculations were as follows:
Recent Accounting Guidance
Recently Adopted Accounting Pronouncements
In February 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842) (ASU 2016-02), which requires a lessee to recognize most leases on the consolidated balance sheet as lease liabilities with corresponding right-of-use assets. We adopted ASU 2016-02 utilizing the modified retrospective transition method at the beginning of the first quarter of 2019. See Note 6, “Leases and Other Commitments” for more information on the impact of our adoption of ASU 2016-02 and related disclosures.
In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (ASU 2017-12), which is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency regarding the scope and results of hedging programs. The guidance in this update is applied using a cumulative-effect adjustment to retained earnings at the beginning of the fiscal year of adoption. ASU 2017-12 is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Our adoption of ASU 2017-12 at the beginning of the first quarter of 2019 did not have a significant impact on our consolidated financial statements.
Recently Issued Accounting Pronouncements Not Yet Adopted
In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. This update is effective for annual periods beginning after December 15, 2019, and interim periods within those periods, and early adoption is permitted. We expect to adopt the standard on its effective date in the first quarter of 2020. We believe the adoption will modify the way we analyze financial instruments, but currently do not expect the adoption to have a material financial impact on our consolidated financial statements.
In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). This new guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. ASU 2017-04 is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. We do not expect the adoption to have a material financial impact on our consolidated financial statements.
In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), which adds and modifies certain disclosure requirements for fair value measurements. Under the new guidance, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, or valuation processes for Level 3 fair value measurements. However, public business entities will be required to disclose the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and related changes in unrealized gains and losses included in other comprehensive income. ASU 2018-13 is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. We do not expect the adoption to have a material financial impact on our consolidated financial statements.
In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15). This new guidance requires a customer in a cloud computing arrangement to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. ASU 2018-15 is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. Application of this guidance can be applied either prospectively or retrospectively. We will adopt the new standard on January 1, 2020 on a prospective basis. We do not expect the adoption to have a material financial impact on our consolidated financial statements, however, the adoption of this standard will result in an increase in capitalized assets related to qualifying cloud computing arrangement implementation costs incurred after the adoption date.
In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, and early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements.
Collaboration with Verily Life Sciences
On November 20, 2018, we entered into an Amended and Restated Collaboration and License Agreement with Verily Life Sciences LLC (an Alphabet Company) and Verily Ireland Limited (collectively, Verily), which we refer to as the Restated Collaboration Agreement. This replaced our original Collaboration and License Agreement with Verily dated August 10, 2015, as amended in October 2016, including the royalty obligations provisions under that original agreement. Pursuant to the Restated Collaboration Agreement, we and Verily have agreed to continue to jointly develop a certain next-generation CGM product, and potentially one or more additional CGM products, for which we will have exclusive commercialization rights.
The Restated Collaboration Agreement also provides us with an exclusive license to use intellectual property of Verily resulting from the collaboration, and certain Verily patents, in the development, manufacture and commercialization of blood-based or interstitial glucose monitoring products more generally (subject to certain exclusions, which are outside of the CGM field as it is commonly understood). It also provides us with non-exclusive license rights under Verily’s other intellectual property rights to develop, manufacture and commercialize those kinds of glucose monitoring products and certain CGM-product companion software functionalities. The Restated Collaboration Agreement requires us to use commercially reasonable efforts to develop, launch and commercialize the CGM product(s) that are the subject of the collaboration according to certain timing and other objectives, and provides for one executive sponsor from each of DexCom and Verily to meet periodically and make decisions related to the collaboration (within a limited scope of authority) by consensus.
In consideration of Verily’s performance of its obligations under the joint development plan of the Restated Collaboration Agreement, the licenses granted to us and the amendment of the original agreement, we have made upfront and incentive payments and we will make potential future milestone payments upon the achievement of certain goals. In the fourth quarter of 2018, we made an initial payment of $250.0 million through the issuance of 1,840,943 shares of our common stock. We recorded a $217.7 million charge in our consolidated statement of operations during 2018 relating to the issuance of this common stock because this milestone payment did not meet the capitalization criteria. The amount of the charge was based on our closing stock price of $118.28 per share on December 28, 2018, the date on which we obtained the necessary regulatory approvals and the transaction closed. During 2019, we made an incentive payment of $3.2 million due to the completion of certain development obligations and recorded as research and development in the consolidated statement of operations. Additional milestone payments of up to a total of $275.0 million may become due and payable by us upon the achievement of future development, product regulatory approval and revenue milestones. These payments may be paid in cash or shares of our common stock, at our election. If we elect to make all $275.0 million of these payments in shares, we will issue a total of 2,025,036 shares of our common stock, based on the volume weighted average trading price during the 15 consecutive days ending on the date of the Restated Collaboration Agreement. Alternatively, if we elect to make all $275.0 million of these payments in cash, any such cash payment would be equal to the number of shares that would otherwise be issued for the given milestone payment multiplied by the value of our stock on the date the relevant milestone is achieved, adjusted for stock splits, dividends, and the like.
The Restated Collaboration Agreement will continue until December 31, 2028, unless terminated by either party upon uncured material breach of the Restated Collaboration Agreement by the other party. Upon achievement of the first revenue milestone event and payment of the corresponding milestone fee by us, the term of the Restated Collaboration Agreement will be extended until December 31, 2033.
Assets and Liabilities Measured at Fair Value on a Recurring Basis
We estimate the fair value of our Level 1 financial instruments, which are in active markets, using unadjusted quoted market prices for identical instruments.
We obtain the fair values for our Level 2 financial instruments, which are not in active markets, from a primary professional pricing source that uses quoted market prices for identical or comparable instruments, rather than direct observations of quoted prices in active markets. Fair values obtained from this professional pricing source can also be based on pricing models whereby all significant observable inputs, including maturity dates, issue dates, settlement date, benchmark yields, reported trades, broker-dealer quotes, issue spreads, benchmark securities, bids, offers or other market related data, are observable or can be derived from, or corroborated by, observable market data for substantially the full term of the asset. We validate the quoted market prices provided by our primary pricing service by comparing the fair values of our Level 2 marketable securities portfolio balance provided by our primary pricing service against the fair values of our Level 2 marketable securities portfolio balance provided by our investment managers.
The following table summarizes financial assets that we measured at fair value on a recurring basis as of December 31, 2019, classified in accordance with the fair value hierarchy:
(1) Includes assets which are held pursuant to a deferred compensation plan for our executives, which consist mainly of mutual funds.
The following table summarizes financial assets that we measured at fair value on a recurring basis as of December 31, 2018, classified in accordance with the fair value hierarchy:
There were no transfers between Level 1 and Level 2 securities during the years ended December 31, 2019 and December 31, 2018. There were no transfers into or out of Level 3 securities during the years ended December 31, 2019 and 2018.
We hold certain other investments that we do not measure at fair value on a recurring basis. The carrying values of these investments are not significant and we include them in other assets in our consolidated balance sheets. It is impracticable for us to estimate the fair value of these investments on a recurring basis due to the fact that these entities are often privately held and limited information is available. We monitor the information that becomes available from time to time and adjust the carrying values of these investments if there are identified events or changes in circumstances that have a significant adverse effect on the fair values.
Fair Value of Senior Convertible Notes
The fair value, based on trading prices (Level 1), of our Senior Convertible Notes were as follows as of the dates indicated:
For more information on the carrying values of our 2022 Notes and 2023 Notes, see Note 5, “Debt.”
Foreign Currency and Derivative Financial Instruments
From time to time we engage in limited hedging transactions to reduce foreign currency risks. The fair values of these derivatives are based on quoted market prices, which are Level 1 inputs, and the derivative instruments are recorded in current assets or current liabilities in our balance sheets consistent with the nature of the instrument at period end. Derivative gains and losses are included in interest and other income, net in our consolidated statement of operations.
As of December 31, 2019, a notional amount of $8.0 million was outstanding to hedge currency risk relating to certain intercompany balances. The resulting impact from the hedging activity on our consolidated financial statements was not significant for the year ended December 31, 2019.
As of December 31, 2018, a notional amount of $60.0 million was outstanding to hedge currency risk relating to certain intercompany balances. Derivative instrument gains on forward exchange contracts were $0.4 million for the twelve months ended December 31, 2018. The fair value of the forward contract exchange derivative instrument liability was $0.2 million as of December 31, 2018. We entered into no foreign currency forward contracts during 2017.
Our foreign currency exposures vary but are primarily concentrated in the British Pound, the Euro, and the Canadian Dollar. We monitor the costs and the impact of foreign currency risks upon our financial results as part of our risk management program. We do not use derivative financial instruments for speculation or trading purposes or for activities other than risk management. We do not require and are not required to pledge collateral for these financial instruments and we do not carry any master netting arrangements to mitigate the credit risk.
Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis
In accordance with authoritative guidance, we measure certain non-financial assets and liabilities at fair value on a non-recurring basis. These measurements are usually performed using the discounted cash flow method and Level 3 inputs. These include items such as non-financial assets and liabilities initially measured at fair value in a business combination and non-financial long-lived assets measured at fair value for an impairment assessment. In general, non-financial assets, including goodwill, intangible assets, and property and equipment, are measured at fair value when there are indicators of impairment and are recorded at fair value only when any impairment is recognized. We recorded no significant impairment losses during the twelve months ended December 31, 2019, 2018 and 2017.
Short-Term Marketable Securities
Short-term marketable securities, consisting of equity securities and debt securities, were as follows as of the dates indicated:
As of December 31, 2019 and 2018, all of our debt securities had contractual maturities of less than twelve months. Gross realized gains and losses on our debt securities for the twelve months ended December 31, 2019, 2018 and 2017 were not significant.
We periodically review our portfolio of debt securities to determine if any investment is other-than-temporarily impaired due to changes in credit risk or other potential valuation concerns. We believe that the investments we held at December 31, 2019 were not other-than-temporarily impaired. Unrealized losses on available-for-sale debt securities at that date were not significant and were due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. We do not intend to sell these investments and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.
The following table reconciles the net gain recognized on equity securities during the twelve months ended December 31, 2019, 2018 and 2017 to the unrealized gain recognized during those periods on equity securities still held at the reporting dates.
Accounts Receivable
Inventory
During the twelve months ended December 31, 2019, we recorded excess and obsolete inventory charges of $14.1 million in cost of sales as a result of our ongoing assessment of sales demand, inventory on hand for each product and the continuous improvement and innovation of our products. During the twelve months ended December 31, 2018, we recorded excess and obsolete inventory charges of $7.3 million in cost of sales primarily as a result of the approval and launch of our G6 system and our ongoing assessment of sales demand and the continuous improvement and innovation of our products.
Property and Equipment
Building and Land. Although we do not legally own these premises, under previous lease accounting standards we were deemed the owner of the construction project during the construction period of our manufacturing facility in Mesa, Arizona under a build-to-suit lease arrangement. As a result of our adoption of ASC 842, we de-recognized the estimated fair value of the building shell that was included in “building and land” in our consolidated balance sheets as of December 31, 2018 and the related lease liability and recorded the difference between the asset and liability as an adjustment to retained earnings at the beginning of the first quarter of 2019. The December 31, 2019 balance in “building and land” represents our finance lease right-of-use assets as a result of our adoption of ASC 842.
Depreciation expense related to property and equipment for the twelve months ended December 31, 2019, 2018 and 2017 was $46.9 million, $28.6 million, and $16.1 million, respectively.
Loss on disposal of property and equipment during the twelve months ended December 31, 2019, 2018 and 2017 recorded in operating expenses was $10.5 million, $5.4 million and $11.0 million, respectively.
Accounts Payable and Accrued Liabilities
Restructuring Plan. In February 2019, our Board of Directors approved a restructuring plan that resulted in the transition of certain of our operations to the Philippines. We incurred total pre-tax charges and costs of approximately $8.0 million, primarily for employee severance benefits under both ongoing and one-time benefit arrangements. We incurred most of these costs in the first half of 2019 and the restructuring activities have been substantially completed as of December 31, 2019.
Accrued Warranty
Warranty costs are reflected in our statements of operations as cost of sales. Reconciliations of our accrued warranty costs for the twelve months ended December 31, 2019 and 2018 were as follows:
Other Long-Term Liabilities
Our adoption of ASC 842 during the first quarter of 2019 affected the balances of finance lease liabilities and deferred rent. See Note 6, “Leases And Other Commitments” for more information on leases.
Senior Convertible Notes
The carrying amounts of our senior convertible notes were as follows as of the dates indicated:
The amount by which the notes’ if-converted value exceeds their principal amount is as of the dates indicated:
The following table summarizes the components of interest expense and the effective interest rates for each of our senior convertible notes for the periods shown.
(1) The discount on the 2022 Notes is being amortized through May 15, 2022. Interest on the 2022 Notes began accruing upon issuance and is payable semi-annually on May 15 and November 15 of each year.
(2) The discount on the 2023 Notes is being amortized through December 1, 2023. Interest on the 2023 Notes began accruing upon issuance and is payable semi-annually on June 1 and December 1 of each year.
0.75% Senior Convertible Notes due 2022
In June 2017, we completed an offering of $400.0 million aggregate principal amount of unsecured senior convertible notes with a stated interest rate of 0.75% and a maturity date of May 15, 2022 (the 2022 Notes). The net proceeds from the offering, after deducting initial purchasers’ discounts and costs directly related to the offering, were approximately $389.0 million. The initial conversion rate of the 2022 Notes is 10.0918 shares per $1,000 principal amount of notes, which is equivalent to a conversion price of approximately $99.09 per share, subject to adjustments. The 2022 Notes may be settled in cash, stock, or a combination thereof, solely at our discretion. We use the if-converted method for assumed conversion of the 2022 Notes to compute the weighted average shares of common stock outstanding for diluted earnings per share.
Since upon conversion by the holders we may elect to settle such conversion in shares of our common stock, cash, or a combination thereof, we accounted for the cash conversion option as an equity instrument classified to stockholders’ equity. As a result, we recognized $72.6 million in additional paid-in-capital during 2017.
No principal payments are due on the 2022 Notes prior to maturity. Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the indenture relating to the 2022 Notes includes customary terms and covenants, including certain events of default after which the 2022 Notes may be due and payable immediately.
Conversion Rights at the Option of the Holders
In the event of a fundamental change (as defined in the indenture related to the 2022 Notes), holders of the 2022 Notes have the right to require us to repurchase for cash all or a portion of their notes at a price equal to 100% of the principal amount of the 2022 Notes, plus any accrued and unpaid interest. Holders of the 2022 Notes who convert their notes in connection with a make-whole fundamental change (as defined in the indenture) or following the delivery by DexCom of a notice of redemption are, under certain circumstances, entitled to an increase in the conversion rate.
Prior to 5:00 p.m., New York City time, on the business day immediately preceding February 15, 2022, holders of the 2022 Notes may convert all or a portion of their notes, in multiples of $1,000 principal amount, only under the following circumstances:
(1)
during any calendar quarter commencing after September 30, 2017 (and only during such calendar quarter), if the last reported sale price of common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the applicable conversion price of the Notes on each such trading day;
(2)
during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each day of that five day consecutive trading day period was less than 98% of the product of the last reported sale price of common stock and the applicable conversion rate of the Notes on such trading day;
(3)
if we call any or all of the Notes for redemption, at any time prior to the close on business on the scheduled trading day immediately preceding the redemption date; or
(4)
upon the occurrence of specified corporate transactions.
On or after February 15, 2022, until 5:00 p.m., New York City time, on the business day immediately preceding the maturity date, holders of the 2022 Notes may convert all or a portion of their notes regardless of the foregoing circumstances.
Circumstance (1) listed above occurred during the quarters ended March 31, 2019, September 30, 2019 and December 31, 2019. As a result, the 2022 Notes became convertible at the option of the holders from April 1, 2019 through June 30, 2019, October 1, 2019 through December 31, 2019 and will remain convertible at the option of the holder from January 1, 2020 through March 31, 2020.
Holders of 2022 Notes with an insignificant principal amount exercised their option to convert their 2022 Notes during the second and fourth quarters of 2019 and we settled these conversions with shares of our common stock. We continue to classify the carrying value of the liability component of the 2022 Notes as long-term debt, and the equity component of the 2022 Notes as permanent equity in our consolidated balance sheets as of December 31, 2019.
Conversion Rights at Our Option
DexCom may not redeem the 2022 Notes prior to May 15, 2020. On or after May 15, 2020, DexCom may redeem for cash all or part of the 2022 Notes, at its option, if the last reported sale price of our common stock has been at least 140% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which DexCom provides notice of redemption. The redemption price will be equal to 100% of the principal amount of the 2022 Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date.
0.75% Senior Convertible Notes due 2023
In November 2018, we completed an offering of $850.0 million aggregate principal amount of unsecured senior convertible notes with a stated interest rate of 0.75% and a maturity date of December 1, 2023 (the 2023 Notes). The net proceeds from the offering, after deducting initial purchasers’ discounts and costs directly related to the offering, were approximately $836.6 million. The initial conversion rate of the 2023 Notes is 6.0869 shares per $1,000 principal amount of notes, which is equivalent to a conversion price of approximately $164.29 per share, subject to adjustments. We entered into transactions for a convertible note hedge (the 2023 Note Hedge) and warrants (the 2023 Warrants) concurrently with the issuance of the 2023 Notes. The 2023 Notes may be settled in cash, stock, or a combination thereof, solely at our discretion. We use the if-converted method for assumed conversion of the 2023 Notes to compute the weighted average shares of common stock outstanding for diluted earnings per share.
Since upon conversion by the holders we may elect to settle such conversion in shares of our common stock, cash, or a combination thereof, we accounted for the cash conversion option as an equity instrument classified to stockholders’ equity. As a result, we recognized $174.4 million in additional paid-in capital during 2018.
No principal payments are due on the 2023 Notes prior to maturity. Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the indenture relating to the 2023 Notes includes customary terms and covenants, including certain events of default after which the 2023 Notes may be due and payable immediately.
Conversion Rights at the Option of the Holders
Holders of the 2023 Notes have the right to require us to repurchase for cash all or a portion of their notes at 100% of their principal amount, plus any accrued and unpaid interest, upon the occurrence of a fundamental change (as defined in the indenture relating to the notes). We will also be required to increase the conversion rate for holders who convert their 2023 Notes in connection with certain fundamental changes occurring prior to the maturity date or following the delivery by DexCom of a notice of redemption.
Holders of the 2023 Notes may convert all or a portion of their notes at their option prior to 5:00 p.m., New York City time, on the business day immediately preceding September 1, 2023, in multiples of $1,000 principal amount, only under the following circumstances:
(1)
during any calendar quarter commencing after March 31, 2019 (and only during such calendar quarter), if the last reported sale price of common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the applicable conversion price of the 2023 Notes on each such trading day;
(2)
during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the 2023 Notes for each day of that five-day consecutive trading day period was less than 98% of the product of the last reported sale price of common stock and the applicable conversion rate of the 2023 Notes on such trading day;
(3)
if we call any or all of the 2023 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or
(4)
upon the occurrence of specified corporate transactions.
On or after September 1, 2023, until 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date, holders of the 2023 Notes may convert all or a portion of their notes regardless of the foregoing circumstances.
Circumstance (1) listed above occurred during the quarter ended December 31, 2019. As a result, the 2023 Notes are convertible at the option of the holders from January 1, 2020 and will remain convertible until March 31, 2020. We continue to classify the carrying value of the liability component of the 2023 Notes as long-term debt, and the equity component of the 2023 Notes as permanent equity in our consolidated balance sheets as of December 31, 2019.
Conversion Rights at Our Option
DexCom may not redeem the 2023 Notes prior to December 1, 2021. On or after December 1, 2021 and prior to September 1, 2023, DexCom may redeem for cash all or part of the 2023 Notes, at its option, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which DexCom provides notice of redemption. The redemption price will be equal to 100% of the principal amount of the 2023 Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date.
2023 Note Hedge
In connection with the offering of the 2023 Notes, in November 2018 we entered into convertible note hedge transactions with two of the initial purchasers of the 2023 Notes (the 2023 Counterparties) entitling us to purchase up to 5.2 million shares of our common stock at an initial price of $164.29 per share, each of which is subject to adjustment. The cost of the 2023 Note Hedge was $218.9 million and we accounted for it as an equity instrument by recognizing $218.9 million in additional paid-in capital during 2018. The 2023 Note Hedge will expire on December 1, 2023. The 2023 Note Hedge is expected to reduce the potential equity dilution upon any conversion of the 2023 Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted 2023 Notes if the daily volume-weighted average price per share of our common stock exceeds the strike price of the 2023 Note Hedge. The strike price of the 2023 Note Hedge initially corresponds to the conversion price of the 2023 Notes and is subject to certain adjustments under the terms of the 2023 Note Hedge. An assumed exercise of the 2023 Note Hedge by us is considered anti-dilutive since the effect of the inclusion would always be anti-dilutive with respect to the calculation of diluted earnings per share.
2023 Warrants
In November 2018, we also sold warrants to the 2023 Counterparties to acquire up to 5.2 million shares of our common stock. The 2023 Warrants require net share settlement and a pro rated number of warrants will expire on each of the 60 scheduled trading days starting on March 1, 2024. We received $183.8 million in cash proceeds from the sale of the 2023 Warrants, which we recorded in additional paid-in capital during 2018. The 2023 Warrants could have a dilutive effect on our earnings per share to the extent that the price of our common stock during a given measurement period exceeds the strike price of the 2023 Warrants. The strike price of the 2023 Warrants is initially $198.38 per share and is subject to certain adjustments under the terms of the warrant agreements. We use the treasury share method for assumed conversion of the 2023 Warrants when computing the weighted average common shares outstanding for diluted earnings per share.
Revolving Credit Agreement
Terms of the Revolving Credit Agreement
On December 19, 2018, we entered into an amended and restated revolving credit agreement (the Credit Agreement) which provides for available principal amount of $200.0 million which can be increased up to $500.0 million at our option subject to customary conditions and approval of our lenders. Borrowings under the Credit Agreement are available for general corporate purposes, including working capital and capital expenditures.
Information related to availability and outstanding borrowings on our Credit Agreement is as follows:
Revolving loans under the Credit Agreement bear interest at our choice of one of two base rates plus a range of applicable margin rates that are based on our leverage ratio. The first base rate is the highest of (a) the publicly announced JPMorgan Chase prime rate, (b) the federal funds rate, or (c) the overnight bank funding rate, and the applicable margin rate ranges from 0.375% to 1.000%. The second base rate is a LIBOR-based rate, and the applicable margin rate ranges from 1.375% to 2.000%. We will also pay a commitment fee of between 0.2% and 0.3%, payable quarterly in arrears, on the average daily unused amount of the revolving facility based on our leverage ratio.
The Credit Agreement will mature on the earlier to occur of (i) December 19, 2023 or (ii) 91 days prior to the maturity date of the 2022 Notes or (iii) 91 days prior to the maturity date of the 2023 Notes if both (a) the aggregate outstanding principal amount of the 2022 Notes or the 2023 Notes, as applicable, is greater than EBITDA for the period of four consecutive fiscal quarters ending prior to such date and (b) unrestricted domestic cash on hand is less than the aggregate outstanding principal amount of the 2022 Notes or the 2023 Notes, as applicable, plus $100.0 million.
Our obligations under the Credit Agreement are guaranteed by our existing and future wholly-owned domestic subsidiaries, and are secured by a first-priority security interest in substantially all of the assets of DexCom and the guarantors, including all or a portion of the equity interests of our domestic subsidiaries and first-tier foreign subsidiaries but excluding real property and intellectual property (which is subject to a negative pledge). The Credit Agreement contains covenants that limit certain indebtedness, liens, investments, transactions with affiliates, dividends and other restricted payments, subordinated indebtedness and amendments to subordinated indebtedness documents, and sale and leaseback transactions of DexCom or any of its domestic subsidiaries. The Credit Agreement also requires us to maintain a maximum leverage ratio and a minimum fixed charge coverage ratio. We were in compliance with these covenants as of December 31, 2019.
Leases
We lease office, manufacturing and warehouse space facilities under various domestic and international operating leases that expire at various times through August 2026. Certain of our leases have renewal options which allow us to extend the lease term typically between three and five years per option and some of our leases have multiple options to extend. We have one finance lease for our manufacturing facility in Mesa, Arizona under a lease that expires in March 2028 with options to renew this lease for four additional five-year terms. Our facility leases generally provide for periodic rent increases and many contain escalation clauses. Certain leases also require us to pay taxes, insurance, and maintenance.
The remaining lease terms of our leases range from less than one year to approximately thirteen years; and represent the non-cancellable periods of the leases, including extension options that we determined are reasonably certain to be exercised.
We adopted ASC 842 utilizing the modified retrospective transition method through a $2.1 million cumulative-effect adjustment to accumulated deficit at the beginning of the first quarter of 2019. We will continue to report financial information for fiscal years prior to 2019 under the previous lease accounting standards and as such prior comparative periods have not been recast. We elected the package of practical expedients permitted under the transition guidance in the new standard, which allowed us to carry forward the historical classification of leases that were in place as of January 1, 2019.
Under the previous lease accounting standards we were deemed the owner of our Mesa, Arizona building during the construction period. As a result of our adoption of ASC 842, we have de-recognized the estimated fair value of the building shell and the related lease liability as of December 31, 2018 and recorded the difference between the asset and liability as an adjustment to retained earnings at the beginning of the first quarter of 2019.
In addition, as a result of our adoption of ASC 842 we recorded operating lease right-of-use assets of $26.7 million, finance lease right-of-use assets of $15.3 million, operating lease liabilities of $40.4 million and finance lease liabilities of $15.9 million in our consolidated balance sheets at the beginning of the first quarter of 2019, with no material impact to our consolidated statement of operations.
Operating lease right-of-use assets and liabilities are presented separately in our consolidated balance sheets. Finance lease right-of-use assets are included in property and equipment and finance lease liabilities are included in accounts payable and accrued liabilities and in other long-term liabilities in our consolidated balance sheets.
As of December 31, 2019, the maturities of our operating and finance lease liabilities were as shown in the table below:
(1) Total future lease cost excludes $5.5 million of legally binding minimum lease payments for leases signed but not yet commenced.
The components of lease expense for the twelve months ended December 31, 2019 were as follows:
(1) Short-term lease cost is primarily related to temporary office space associated with the transition of certain operations to the Philippines.
(2) Variable lease costs are primarily related to common area maintenance charges and property taxes.
Prior to January 1, 2019, we recorded operating lease rent expense under ASC 840 on a straight-line basis over the non-cancellable lease term. Rent expense for the twelve months ended December 31, 2018 and 2017 was $12.5 million and $11.1 million, respectively.
Other information related to leases was as shown in the table below. All figures include the leases recorded at the beginning of the first quarter of 2019 as a result of our adoption of ASC 842.
Amortization of operating lease right-of-use asset included in cash flows from operating activities in the Consolidated Statements of Cash Flows was $9.1 million for the twelve months ended December 31, 2019.
Purchase Commitments
We are party to various purchase arrangements related to our manufacturing and research and development activities. As of December 31, 2019, we had approximately $165.8 million of open purchase orders and contractual obligations in the ordinary course of business, most of which are due within one year.
Litigation
On March 28, 2016, AgaMatrix, Inc., or AgaMatrix, filed a patent infringement lawsuit against us in the U.S. District Court for the District of Oregon, asserting that certain of our products infringe three patents held by AgaMatrix. (After filing suit, AgaMatrix reorganized its business and the Court granted AgaMatrix’s motion to substitute the newly created entity WaveForm Technologies, Inc., as the plaintiff following AgaMatrix’s transfer of the three asserted patents to WaveForm.) DexCom filed petitions for inter partes review with the Patent Trial and Appeal Board, or PTAB, of the U.S. Patent and Trademark Office, challenging each of the three asserted patents as being unpatentable in view of prior art. The PTAB issued a Final Written Decision for each of the first two patents on February 28, 2018, where the PTAB found the majority of asserted claims from the first patent unpatentable and the remaining claims under review not unpatentable. The PTAB found all claims under review from the second patent not unpatentable. On September 12, 2018, the PTAB found all of the asserted claims in the third patent unpatentable. In October 2018, we filed in the District Court a motion for summary judgment that all remaining asserted claims are invalid. The District Court granted that motion and, on August 23, 2019, entered judgment in our favor. On September 6, 2019, WaveForm appealed the judgment. The appeal is pending and no hearing date has been set.
We have also filed several lawsuits against AgaMatrix. We filed a patent infringement lawsuit against AgaMatrix in the United States District Court for the Central District of California, or C.D. Cal., in which a Final Judgment of non-infringement was entered by the C.D. Cal judge on February 23, 2018 and affirmed on appeal by the Federal Circuit on March 7, 2019. AgaMatrix was awarded attorneys’ fees for this lawsuit. As of December 31, 2019, we have accrued an immaterial amount for those fees. The fee decision is currently on appeal to the Federal Circuit. On September 15, 2017, we filed a patent infringement lawsuit against AgaMatrix in the United States District Court for the District of Delaware, asserting certain single-point blood glucose monitoring products of AgaMatrix infringe two patents held by us. In addition, on September 18, 2017, we filed a Complaint against AgaMatrix in the International Trade Commission, referred to as the ITC, requesting that the ITC institute an investigation and issue an order excluding certain products of AgaMatrix from importation into or sale in the United States based on AgaMatrix’s infringement of the same two patents asserted in the Delaware litigation. The investigation was terminated by the ITC on April 4, 2019 with a finding of non-infringement. The decision is currently on appeal.
Neither the outcome of these lawsuits nor the amount and range of potential loss associated with the lawsuits can be assessed at this time. Other than the attorneys’ fees described above, as of December 31, 2019 we have accrued no amounts for contingent losses associated with these suits.
We are subject to various claims, complaints and legal actions that arise from time to time in the normal course of business, including commercial insurance, product liability and employment related matters. In addition, from time to time we may bring claims or initiate lawsuits against various third parties with respect to matters arising out of the ordinary course of our business, including commercial and employment related matters. We do not expect that the resolution of these matters would, or will, have a material adverse effect or material impact on our financial position or results of operations.
Income (loss) before income taxes subject to taxes in the following jurisdictions is as follows:
Significant components of the provision for income taxes are as follows:
At December 31, 2019, we had federal, state and foreign tax net operating loss carryforwards of approximately $438.8 million, $324.1 million, and $124.1 million, respectively. The federal and state tax loss carryforwards will begin to expire in 2027 and 2020, respectively, unless previously utilized. The foreign net operating losses carry forward indefinitely.
At December 31, 2019, we also had federal and state research and development tax credit carryforwards of approximately $54.4 million and $52.7 million, respectively. $0.1 million of the federal research and development tax credit will begin to expire in 2020, unless previously utilized. The state research and development tax credit will carryforward indefinitely until utilized.
Utilization of net operating losses and credit carryforwards is subject to an annual limitation due to ownership change limitations provided by Section 382 and 383 of the Internal Revenue Code of 1986, as amended, and similar state provisions. An ownership change limitation occurred as a result of the stock offering completed in February 2009. The limitation will likely result in approximately $2.1 million of U.S. income tax credits that will expire unused. The related deferred tax assets have been removed from the components of our deferred tax assets as summarized in the table below. We performed a Section 382 study on the remaining federal and state net operating losses and tax credit carryforwards and have determined that there is no annual limitation on them as of December 31, 2019.
Significant components of our deferred tax assets as of December 31, 2019 and 2018 are shown below. A valuation allowance of approximately $332.2 million has been established as of December 31, 2019 to offset the deferred tax assets, as realization of such assets is uncertain. We maintain a deferred tax liability related to indefinite-lived intangible assets that is not netted against the deferred tax assets. Reversal of the taxable temporary difference for these intangible assets cannot serve as a source of income for realization of the deferred tax assets because the deferred tax liability will not reverse until the intangible assets are sold or written down due to impairment.
Significant judgment is required to evaluate the need for a valuation allowance against deferred tax assets. We review all available positive and negative evidence, including projections of pre-tax book income, earnings history, and reliability of forecasting. A valuation allowance is established when it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2019, we have maintained a full valuation allowance on our deferred tax assets since inception based on our historical losses and the uncertainty of generating future taxable income to utilize our loss and credit carryforwards. A future release of our valuation allowance will result in a material tax benefit recognized in the quarter of the release.
As of December 31, 2019, deferred tax assets for which any subsequently recognized tax benefits will be credited to additional paid-in capital rather than to income tax benefit totaled $55.7 million.
The reconciliation between our effective tax rate on income (loss) from continuing operations and the statutory rate is as follows:
The following table summarizes the activity related to our gross unrecognized tax benefits:
Due to the valuation allowance recorded against our deferred tax assets, none of the total unrecognized tax benefits as of December 31, 2019 would reduce our annual effective tax rate if recognized. Interest and penalties are classified as a component of income tax expense and were not material for any period presented. Due to net operating losses incurred, tax years from 1999 and forward for federal and state purposes and from 2016 and forward for foreign jurisdictions remain open to examination by the major taxing jurisdictions to which we are subject. The IRS commenced an audit of our 2015 and 2016 federal income tax returns in February 2018. The audit closed in June 2019 with no significant changes to our unrecognized tax benefits.
We operate under a tax holiday in the Philippines, which is effective through December 31, 2023, and may be extended for another three years if certain additional requirements are satisfied. The tax holiday is conditional upon remaining in good standing, committing no violation of PEZA Rules and Regulations, pertinent circulars and directives. The impact of this tax holiday decreased foreign taxes by $0.2 million in 2019.
401(k) Plan
We have a defined contribution 401(k) retirement plan (the 401(k) Plan) covering substantially all employees in the United States that meet certain age requirements. Employees who participate in the 401(k) Plan may contribute up to 75% of their compensation each year, subject to Internal Revenue Service limitations and the terms and conditions of the plan. Under the terms of the 401(k) Plan, we may elect to match a discretionary percentage of contributions. In April 2018, we began matching 50% of contributions up to 4% of annual compensation. Total matching contributions were $4.8 million and $2.6 million for the twelve months ended December 31, 2019, and 2018, respectively.
Employee Stock Purchase Plan, or ESPP
Under the 2015 Employee Stock Purchase Plan (the 2015 ESPP) eligible employees can purchase shares of our common stock at semi-annual intervals through periodic payroll deductions during defined Offering Periods. A total of up to 1.5 million shares may be issued under the 2015 ESPP and it expires upon the earliest to occur of (a) termination of the 2015 ESPP by our board of directors, (b) issuance of all of the shares of common stock reserved for issuance under the plan, or (c) May 28, 2025.
Payroll deductions may not exceed 10% of the participant’s cash compensation subject to certain limitations, and the purchase price will not be less than 85% of the lower of the fair market value of the common stock at either the beginning of the applicable Offering Period or the Purchase Date.
We issued 150,408 and 189,904 and 122,857 shares of common stock under the 2015 ESPP during the twelve months ended December 31, 2019, 2018 and 2017, respectively.
Equity Incentive Plans
In May 2015, we adopted the Amended and Restated 2015 Equity Incentive Plan (the 2015 Plan), which replaced our 2005 Equity Incentive Plan and provides for the grant of incentive and nonstatutory stock options, restricted stock, stock bonuses, stock appreciation rights, and restricted stock units to employees, directors or consultants of the Company. On May 30, 2019 our stockholders approved an increase to the maximum number of shares that may be issued under the 2015 Plan. We are permitted to issue up to 9.8 million shares under the 2015 Plan.
Treasury Stock
Repurchased shares of our common stock are held as treasury shares until they are reissued or retired. When we reissue treasury stock, if the proceeds from the sale are more than the average price we paid to acquire the shares we record an increase in additional paid-in capital. Conversely, if the proceeds from the sale are less than the average price we paid to acquire the shares, we record a decrease in additional paid-in capital to the extent of increases previously recorded for similar transactions and a decrease in retained earnings for any remaining amount.
We issue new shares of common stock to satisfy option exercises and RSU vesting under our employee equity incentive plans. We have not yet determined the ultimate disposition of the 0.8 million shares that we repurchased in 2018, and consequently we continue to hold them as treasury shares rather than retiring them. No shares of our common stock were repurchased during 2019.
Stock Options
We have not granted any stock options since 2010. As of December 31, 2019 we have 28,385 options outstanding, all of which are in-the-money. The options have a weighted- average remaining contractual term of 0.27 years, a weighted- average exercise price of $10.11 per share, and an aggregate intrinsic value of $5.9 million. The aggregate intrinsic value of options outstanding and exercisable is calculated as the difference between the exercise price of the underlying options and the $218.74 per share market price of our common stock at December 31, 2019.
The total intrinsic value of stock options exercised as of the date of exercise was as follows:
Restricted Stock Units (RSUs)
RSU awards typically vest annually over three or four years and vesting is subject to continued services. A summary of our RSU activity for the twelve months ended December 31, 2019, 2018 and 2017 is as follows:
The total vest-date fair value of RSUs vested was $207.2 million, $120.9 million and $144.5 million for the twelve months ended December 31, 2019, 2018 and 2017, respectively.

We estimate the fair value of ESPP purchase rights on the date of grant using the Black-Scholes option pricing model and the assumptions below for the specified reporting periods.
At December 31, 2019, unrecognized estimated compensation costs related to unvested restricted stock units and ESPP shares totaled $119.3 million and are expected to be recognized through 2022.
Reportable Segments
An operating segment is identified as a component of a business that has discrete financial information available and for which the chief operating decision maker must decide the level of resource allocation. In addition, the guidance for segment reporting indicates certain quantitative materiality thresholds. None of the components of our business meet the definition of an operating segment.
We currently consider our operations to be, and manage our business globally within, one reportable segment, which is consistent with how our President and Chief Executive Officer, who is our chief operating decision maker, reviews our business, makes investment and resource allocation decisions, and assesses operating performance.
Disaggregation of Revenue
DexCom is domiciled in the United States. We sell our CGM systems through a direct sales force in the United States, Canada and some countries in Europe, and through distribution arrangements in the United States, and certain countries in Africa, Asia, Europe, Latin America, and the Middle East, as well as Australia, Canada, and New Zealand. We disaggregate our revenue from contracts by geography and by major sales channel as we believe they best depict how the nature, amount and timing of revenues and cash flows are affected by economic factors.
Revenues by geographic region
During the twelve months ended December 31, 2019, 2018 and 2017, no individual country outside the United States generated revenue that represented more than 10% of our total revenue.
