2021 Annual Report. We are in compliance with all of our debt covenants at September 30, 2022. We believe we will be able to continue to comply with the financial covenants contained in our credit facility through its maturity.
Our assets consist primarily of investments in operating subsidiaries, and our ability to service our obligations, including the Senior Secured Notes, depends in part upon the distribution of earnings of our subsidiaries, whether in the form of dividends, advances or payments on account of intercompany obligations or otherwise. Our Senior Secured Notes are collateralized by, among other things, a first priority lien on (i) 100% of the common stock or other ownership interests of each existing and future direct domestic subsidiary of KII and the guarantors, and (ii) 65% of the voting common stock or other ownership interests and 100% of the non-voting common stock or other ownership interests of each non-U.S. subsidiary that is directly owned by KII or any guarantor. Our Global Revolver is collateralized by, among other things, a first priority lien on the borrower’s trade receivables and inventories. See Note 5 to our Condensed Consolidated Financial Statements.
Future cash requirements
Liquidity
Our primary source of liquidity on an ongoing basis is cash flows from operating activities which is generally used to (i) fund capital expenditures, (ii) repay any short-term indebtedness incurred for working capital purposes, (iii) provide for the payment of dividends and (iv) fund purchases of shares of our common stock under our stock repurchase program. From time-to-time we will incur indebtedness, generally to (i) fund short-term working capital needs, (ii) refinance existing indebtedness or (iii) fund major capital expenditures or the acquisition of other assets outside the ordinary course of business. We will also from time-to-time sell assets outside the ordinary course of business and use the proceeds to (i) repay existing indebtedness, (ii) make investments in marketable and other securities, (iii) fund major capital expenditures or the acquisition of other assets outside the ordinary course of business or (iv) pay dividends.
The TiO2 industry is cyclical, and changes in industry economic conditions significantly impact earnings and operating cash flows. Changes in TiO2 pricing, production volumes and customer demand, among other things, could significantly affect our liquidity.
We routinely evaluate our liquidity requirements, alternative uses of capital, capital needs and availability of resources in view of, among other things, our dividend policy, our debt service, our capital expenditure requirements and estimated future operating cash flows. As a result of this process, we have in the past and may in the future seek to reduce, refinance, repurchase or restructure indebtedness, raise additional capital, repurchase shares of our common stock, modify our dividend policy, restructure ownership interests, sell interests in our subsidiaries or other assets, or take a combination of these steps or other steps to manage our liquidity and capital resources. Such activities have in the past and may in the future involve related companies. In the normal course of our business, we may investigate, evaluate, discuss and engage in acquisition, joint venture, strategic relationship and other business combination opportunities in the TiO2 industry. In the event of any future acquisition or joint venture opportunity, we may consider using then-available liquidity, issuing our equity securities or incurring additional indebtedness.
At September 30, 2022 we had aggregate cash, cash equivalents and restricted cash on hand of $344.4 million, of which $115.3 million was held by non-U.S. subsidiaries. Following implementation of a territorial tax system under the 2017 Tax Act, repatriation of any cash and cash equivalents held by our non-U.S. subsidiaries would not be expected to result in any material income tax liability as a result of such repatriation. Our $225 million Global Revolver we entered into in April 2021, which replaced our North American and European facilities, matures in April 2026 and currently approximately $207 million is available for borrowing under this facility and we could borrow all available amounts without violating our existing debt covenants. See Note 5 to our Condensed Consolidated Financial Statements. Based upon our expectation for the TiO2 industry and anticipated demands on cash resources, we expect to have sufficient liquidity to meet our short-term obligations (defined as the twelve-month period ending September 30, 2023) and our long-term obligations (defined as the five-year period ending September 30, 2027, our time period for long-term budgeting). If actual developments differ from our expectations, our liquidity could be adversely affected.
