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 June 30, 2024, we had aggregate cash, cash equivalents and restricted cash on hand of $140.3 million, of which $100.9 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 June 30, 2024, the full $225 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 June 30, 2025) and our long-term obligations (defined as the five-year period ending June 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 $50 million in capital expenditures primarily to maintain and improve our existing facilities during 2024, including $8.1 million in expenditures through June 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 June 30, 2024, we have 1,017,518 shares available for repurchase under a stock repurchase program authorized by our board of directors.
Commitments and contingencies
