Capital commitments

The Group’s capital commitments primarily relate to commitments on construction of office building and warehouses. Total capital commitments contracted but not yet reflected in the consolidated financial statements amounted to RMB2,658,773 as of December 31, 2017. All of these capital commitments will be fulfilled in the following years according to the construction progress.

Long-Term Debt Obligations

The Group’s long-term debt obligations include unsecured senior notes and nonrecourse securitization debt which consists of asset-backed debt securities issued in connection with securitization of certain financial assets (Note 2(v)). The amounts exclude the corresponding interest payable. The expected repayment schedule of the unsecured senior notes has been disclosed in Note 18. The expected repayment amount of the nonrecourse securitization debt is approximately RMB12,684,881 and RMB4,475,238 for the years ended December 31, 2018 and 2019, respectively.

Legal proceedings

From time to time, the Group is subject to legal proceedings and claims in the ordinary course of business. Third parties assert patent infringement claims against the Group from time to time in the form of letters, lawsuits and other forms of communication. In addition, from time to time, the Group receives notification from customers claiming that they are entitled to indemnification or other obligations from the Group related to infringement claims made against them by third parties. Litigation, even if the Group is ultimately successful, can be costly and divert management’s attention away from the day-to-day operations of the Group.

The Group records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Group reviews the need for any such liability on a regular basis. The Group has not recorded any material liabilities in this regard as of December 31, 2015, 2016 and 2017.
