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. We may also from time to time engage in preliminary discussions with existing or potential investors regarding the timing or terms of any such refinancing or other potential transaction. 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, 2024, we had aggregate cash, cash equivalents and restricted cash on hand of $102.9 million, of which $65.3 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. As amended, our Global Revolver matures in July 2029, and at September 30, 2024 approximately $268 million is available for borrowing under this facility. The borrowing base is calculated quarterly and the amount available for borrowing may change based on applicable quarter end balances. 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, 2025) and our long-term obligations (defined as the five-year period ending September 30, 2029, our time period for long-term budgeting). If actual developments differ from our expectations, our liquidity could be adversely affected.
Capital expenditures
We intend to invest approximately $42 million in capital expenditures primarily to maintain and improve our existing facilities during 2024, including $17.2 million in expenditures through September 30, 2024. It is possible we will delay planned capital projects based on market conditions including but not limited to expected demand, the general availability of materials, equipment and supplies necessary to complete such projects.
Stock repurchase program
At September 30, 2024, we have 1,017,518 shares available for repurchase under a stock repurchase program authorized by our board of directors.
