Commitments and Contingencies Commitments Except for the items below, there have been no material changes to the Company's commitments compared to the commitments described in Note 16, Commitments and Contingencies , in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K. Leases The Company leases its facilities and certain equipment under non-cancelable operating leases that have remaining lease terms of 1 to 7 years and 1 to 3 years, respectively. Each leased facility is subject to an individual lease or sublease, which could provide various options to extend or terminate the lease agreement. Facilities are primarily comprised of corporate offices, data centers, and R&amp;D facilities. Equipment includes vehicles and various office equipment. The Company also has variable lease payments that are primarily comprised of common area maintenance and utility charges. The Company's lease agreements do not contain any residual value guarantees or restrictive covenants. The components of lease costs and other information related to leases were as follows (in millions, except years and percentages): Three Months Ended March 31, 2019 Operating lease cost $ 11.9 Variable lease cost 3.1 Total lease cost $ 15.0 Operating cash outflows from operating leases $ 11.6 ROU assets obtained in exchange for new operating lease liabilities $ 0.6 Weighted average remaining lease term (years) 6.0 Weighted average discount rate 4.4 % As of March 31, 2019 , future minimum operating lease payments for each of the next five years and thereafter is as follows (in millions): Years Ending December 31, Amount 2019 $ 32.9 2020 47.3 2021 40.4 2022 32.7 2023 29.8 Thereafter 60.3 Total lease payments 243.4 Less: interest (30.0 ) Total $ 213.4 Balance Sheet Information Other accrued liabilities 36.7 Long-term operating lease liabilities 176.7 Total $ 213.4 Purchase Commitments with Contract Manufacturers and Suppliers In order to reduce manufacturing lead times and in the interest of having access to adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $632.4 million as of March 31, 2019 . The Company establishes a liability in connection with purchase commitments related to quantities in excess of its demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on the Companys demand forecast or customer orders. As of March 31, 2019 , the Company had accrued $32.8 million based on its estimate of such charges. Indebtedness In February 2019, the Company paid the aggregate principal amount of $350.0 million on its 3.125% senior notes upon maturity. Legal Proceedings Investigations The Company previously disclosed that it has been the subject of investigations by the U.S. Securities and Exchange Commission ("SEC") and the U.S. Department of Justice ("DOJ") into possible violations by the Company of the U.S. Foreign Corrupt Practices Act. In cooperation with these investigations, the Company and the Audit Committee of the Board of Directors, with the assistance of outside counsel and other independent advisors, conducted a thorough internal investigation. As a result of its internal investigation, the Company made significant improvements in its internal controls and carried out a number of disciplinary actions. In the fourth quarter of 2017, the DOJ notified the Company that the DOJ has closed its investigation related to these matters without taking any action against the Company. The Company is continuing to fully cooperate with the SECs ongoing investigation, and based on the Companys recent communications with the Staff of the SEC, the Company believes that it is likely that the Staff of the SEC will seek to bring an enforcement action against the Company. The Company believes it is probable that it could incur a loss and has established an estimated legal reserve of $12.0 million related to the ongoing SEC investigation; however, as discussions are continuing, there can be no assurance as to the timing or the terms of any final resolution of this matter. Other Litigations and Investigations In addition to the investigations discussed above, the Company is involved in other investigations, disputes, litigations, and legal proceedings. The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company intends to aggressively defend itself in these matters, and while there can be no assurances and the outcome of these matters is currently not determinable, the Company currently believes that none of these existing claims or proceedings are likely to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses.
