COMMITMENTS AND CONTINGENCIES Commitments We have entered into non-cancellable operating and finance leases and financing obligations for equipment and office, fulfillment, sortation, delivery, data center, physical store, and renewable energy facilities. The following summarizes our principal contractual commitments, excluding open orders for purchases that support normal operations and are generally cancellable, as of September 30, 2020 (in millions): Three Months Ended December 31, Year Ended December 31, 2020 2021 2022 2023 2024 Thereafter Total Long-term debt principal and interest $ 282 $ 2,188 $ 2,647 $ 3,271 $ 4,272 $ 38,738 $ 51,398 Operating lease liabilities 1,139 5,032 4,584 4,204 3,865 23,190 42,014 Finance lease liabilities, including interest 2,363 10,145 6,507 2,753 1,291 6,742 29,801 Financing obligations, including interest 48 211 214 217 220 3,694 4,604 Unconditional purchase obligations (1) 416 4,027 3,562 3,194 3,049 2,296 16,544 Other commitments (2) (3) 1,260 3,963 3,290 2,268 2,238 23,612 36,631 Total commitments $ 5,508 $ 25,566 $ 20,804 $ 15,907 $ 14,935 $ 98,272 $ 180,992 ___________________ (1) Includes unconditional purchase obligations related to certain products offered in our Whole Foods Market stores and long-term agreements to acquire and license digital media content that are not reflected on the consolidated balance sheets. For those digital media content agreements with variable terms, we do not estimate the total obligation beyond any minimum quantities and/or pricing as of the reporting date. Purchase obligations associated with renewal provisions solely at the option of the content provider are included to the extent such commitments are fixed or a minimum amount is specified. (2) Includes the estimated timing and amounts of payments for rent and tenant improvements associated with build-to-suit lease arrangements and lease arrangements prior to the lease commencement date, liabilities associated with digital media content agreements with initial terms greater than one year, and asset retirement obligations. (3) Excludes approximately $3.0 billion of accrued tax contingencies for which we cannot make a reasonably reliable estimate of the amount and period of payment, if any. Pledged Assets As of December 31, 2019 and September 30, 2020, we have pledged or otherwise restricted $994 million and $921 million of our cash, cash equivalents, and marketable securities, and certain property and equipment as collateral for real estate leases, amounts due to third-party sellers in certain jurisdictions, debt, and standby and trade letters of credit. Additionally, we have pledged our cash and seller receivables for debt related to our Credit Facility. See Note 5  Debt. Other Contingencies We are subject to claims related to various indirect taxes (such as sales, value added, consumption, service, and similar taxes), including in jurisdictions in which we already collect and remit such taxes. If the relevant taxing authorities were successfully to pursue these claims, we could be subject to significant additional tax liabilities. For example, in June 2017, the State of South Carolina issued an assessment for uncollected sales and use taxes for the period from January 2016 to March 2016, including interest and penalties. South Carolina is alleging that we should have collected sales and use taxes on transactions by our third-party sellers. In September 2019, the South Carolina Administrative Law Court ruled in favor of the Department of Revenue and we have appealed the decision to the state Court of Appeals. We believe the assessment is without merit and intend to defend ourselves vigorously in this matter. If other tax authorities were successfully to seek additional adjustments of a similar nature, we could be subject to significant additional tax liabilities. Legal Proceedings The Company is involved from time to time in claims, proceedings, and litigation, including the matters described in Item 8 of Part II, Financial Statements and Supplementary Data  Note 7  Commitments and Contingencies  Legal Proceedings of our 2019 Annual Report on Form 10-K and in Item 1 of Part I, Financial Statements  Note 4  Commitments and Contingencies  Legal Proceedings of our Quarterly Reports on Form 10-Q for the periods ended March 31, 2020 and June 30, 2020. In addition, we are regularly subject to claims, litigation, and other proceedings, including potential regulatory proceedings, involving patent and other intellectual property matters, taxes, labor and employment, competition and antitrust, privacy and data protection, consumer protection, commercial disputes, goods and services offered by us and by third parties, and other matters. The outcomes of our legal proceedings and other contingencies are inherently unpredictable, subject to significant uncertainties, and could be material to our operating results and cash flows for a particular period. We evaluate, on a regular basis, developments in our legal proceedings and other contingencies that could affect the amount of liability, including amounts in excess of any previous accruals and reasonably possible losses disclosed, and make adjustments and changes to our accruals and disclosures as appropriate. For the matters we disclose that do not include an estimate of the amount of loss or range of losses, such an estimate is not possible or is immaterial, and we may be unable to estimate the possible loss or range of losses that could potentially result from the application of non-monetary remedies. Until the final resolution of such matters, if any of our estimates and assumptions change or prove to have been incorrect, we may experience losses in excess of the amounts recorded, which could have a material effect on our business, consolidated financial position, results of operations, or cash flows.
