At November 30, 2023, our liquidity and capital resources included working capital of $814.3 million inclusive of cash of $65.1 million.
On December 14, 2022, we entered into a new credit agreement with various financial institutions as lenders and Wells Fargo Bank, N.A. as administrative agent for the lenders (the “Credit Agreement”). The Credit Agreement provides for a $620 million unsecured revolving credit facility (the “Revolving Credit Facility”) that we can draw upon for working capital and general corporate purposes. Under certain circumstances, we may request an increase to the lending commitments under the Credit Agreement by an aggregate amount of up to $300 million, not to exceed $920 million in total. The Credit Agreement expires on December 14, 2027.
At November 30, 2023, borrowings outstanding under the Revolving Credit Facility were $277.0 million and there were approximately $11.0 million of outstanding letters of credit, which reduced the availability under this facility to $332.0 million. There are no other terms or covenants limiting the availability of the Revolving Credit Facility.
As of November 30, 2023, we also had other financing arrangements that did not limit availability on our Revolving Credit Facility, including outstanding letters of credit of $11.7 million and foreign lines of credit of $9.4 million.
We maintain a Purchase Agreement with Citibank N.A. (“Purchaser”) for the sale, from time to time, of certain accounts receivable due from certain customers (the “Purchase Agreement”). Under the Purchase Agreement, the maximum amount of receivables sold is limited to $150 million and Purchaser may, but is not required to, purchase the eligible receivables we offer to sell. The term of the Purchase Agreement expires after February 22, 2024, but, the Purchase Agreement may be terminated earlier under certain circumstances. The term of the Purchase Agreement is automatically extended for annual terms unless either party provides advance notice that they do not intend to extend the term.
We have no retained interests in the sold receivables, other than limited recourse obligations in certain circumstances, and only perform collection and administrative functions for the Purchaser. We account for these receivable transfers as sales under ASC 860, Transfers and Servicing, and de-recognize the sold receivables from our Consolidated Balance Sheet. At November 30, 2023, we have utilized $12.6 million which reduced the availability under the Purchase Agreement to $137.4 million.
At November 30, 2023, we were in compliance with all financial and other covenants under each of our financing arrangements.
During the second quarter of fiscal 2024, we continued to experience delayed collections from one of our significant regional airline customers and issued the customer a Notice of Payment and Other Defaults to request payment and reserve our rights under our agreements. Though we currently expect full payment from the customer of all amounts due and do not believe a reserve for credit loss is warranted, the customer’s financial condition may continue to deteriorate and we may in the future experience loss due to a default by the customer and the related nonpayment of account receivable balances. Our Condensed Consolidated Balance Sheet as of November 30, 2023 included accounts receivable of $11.9 million, including $5.4 million past due, and contract assets of $9.4 million related to this customer.
On December 16, 2021, our Board of Directors authorized a renewal of our stock repurchase program, under which we may repurchase up to $150 million of our common stock with no expiration date. During fiscal 2023, we repurchased 1.2 million shares for an aggregate purchase price of $50.1 million. No repurchases were made during the six-month period ended November 30, 2023. Since inception of the renewal authorization, we have repurchased 2.2 million shares for an aggregate purchase price of $92.4 million. The timing and amount of repurchases are subject to prevailing market conditions and other considerations, including our liquidity and acquisition and other investment opportunities.
Cash Flows from Operating Activities
Net cash used in operating activities–continuing operations was $1.1 million in the six-month period ended November 30, 2023 compared to cash used of $38.9 million in the prior year period. The decrease in cash used from the prior year of $37.8 million was primarily attributable to working capital changes, including the timing of payments for inventory investments in both new parts and used serviceable material in the current year period.
Cash Flows from Investing Activities
Net cash used in investing activities was $20.3 million in the six-month period ended November 30, 2023 compared to $18.3 million in the prior year period. The increase in cash used in investing activities over the prior year of $2.0 million was primarily related to increased expenditures for capital equipment in the current year period.
