As of October 31, 2022 and January 31, 2022, we had letters of credit in the aggregate amount of $18.6 million in connection with our operating leases and voluntary disability insurance (VDI) program, which were primarily issued under the available sublimit for the issuance of letters of credit in conjunction with a secured credit agreement as disclosed in Note 9.

Our purchase obligations relate primarily to infrastructure services and IT software and support services costs. As of October 31, 2022, future payments under non-cancellable contractual purchases, which were not recognized on our condensed consolidated balance sheet, are as follows, shown in accordance with the payment due date (in thousands):


Fiscal years ending January 31:
2023	$	2,878
2024		5,149
2025		130,771
2026		556
2027		264,139
Total	$	403,493

Our contracts for infrastructure services and IT software, which have terms ranging from 2 to 8 years, support our long-term goals of improving gross margin. In addition to the purchase obligations included above, as of October 31, 2022, we recognized a total of $8.8 million related to non-cancellable contractual purchases, which were included in accounts payable, accrued expenses and other current liabilities and other long-term liabilities on the condensed consolidated balance sheet. $8.6 million and $0.2 million is due to be paid in the remainder of the fiscal year ending January 31, 2023 and the fiscal year ending January 31, 2024, respectively.

From time to time, we are subject to litigation and claims that arise in the ordinary course of business. We investigate litigation and claims as they arise and accrue estimates for resolution of legal and other contingencies when losses are probable and estimable. Although the results of litigation and claims cannot be predicted with certainty, we believe there was not at least a reasonable possibility that we had incurred a material loss with respect to such loss contingencies as of October 31, 2022.
