Liquidity and Capital Resources
Our main sources of liquidity are cash on hand, internally generated cash flow from operations, our bank credit facility and capital market transactions. At June 30, 2025, we had approximately $1.2 billion of liquidity consisting of $134,000 of cash on hand and $1.2 billion of availability under our bank credit facility. Our borrowing base can be adjusted as a result of changes in commodity prices, acquisitions or divestitures of proved properties or financing activities. We may draw on our bank credit facility to meet short-term cash requirements.
We expect our 2025 capital program to be funded by cash flows from operations. During the six months ended June 30, 2025, we generated $666.3 million of cash flows from operating activities.
Bank Credit Facility
Our bank credit facility is secured by substantially all of our assets. As of June 30, 2025, we had a balance of $125.0 million on our credit facility and we maintained a borrowing base of $3.0 billion and aggregate lender commitments of $1.5 billion. We have undrawn letters of credit of $164.1 million as of June 30, 2025, which reduce our borrowing capacity under our bank credit facility.
The borrowing base is subject to regular, semi-annual re-determinations and is dependent on a number of factors but primarily the lenders' assessment of our future cash flows. Our scheduled borrowing base re-determination was completed in March 2025 with our borrowing base and lender commitments reaffirmed. We currently must comply with certain financial and non-financial covenants, including limiting dividend payments, debt incurrence and requirements that we maintain certain financial ratios (as defined in our bank credit facility agreement). We were in compliance with all such covenants at June 30, 2025.
Capital Requirements
We use cash for the development, exploration and acquisition of natural gas properties and for the payment of gathering, transportation and processing costs, operating, general and administrative costs, taxes and debt obligations, including interest, dividends and share repurchases. Expenditures for the development, exploration and acquisition of natural gas properties are the primary use of our capital resources. During first six months 2025, we used operating cash flows to fund $317.5 million of capital expenditures as reported in our consolidated statement of cash flows within investing activities. The amount of our future capital expenditures will depend upon a number of factors including our cash flows from operating, investing and financing activities, infrastructure availability, supply and demand fundamentals and our ability to execute our development program. In addition, the impact of commodity prices on investment opportunities, the availability of capital and the timing and results of our development activities may lead to changes in funding requirements for future development. We periodically review our budget to assess changes in current and projected cash flows, debt requirements and other factors.
We may from time to time repurchase or redeem all or portions of our outstanding debt securities for cash, through exchanges for other securities or a combination of both. Such repurchases or redemptions may be made in open market transactions and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
Cash Dividend Payments
On May 30, 2025, our board of directors announced the approval of a dividend of $0.09 per share payable on June 27, 2025, to stockholders of record at the close of business on June 13, 2025. The determination of the amount of future dividends, if any, to be declared and paid is at the sole discretion of the board of directors and primarily depends on cash flow, capital expenditures, debt covenants and various other factors.
Stock Repurchase Program
Our total remaining share repurchase authorization was approximately $895.7 million at June 30, 2025.
Other Sources of Liquidity
We have a universal shelf registration statement filed with the SEC under which we, as a well-known seasoned issuer for purposes of SEC rules, have the future ability to sell an indeterminate amount of various types of debt and equity securities.
Cash Contractual Obligations
Our contractual obligations include long-term debt, operating leases, derivative obligations, asset retirement obligations and transportation, processing and gathering commitments including the divestiture contractual commitment that we incurred in conjunction with the sale of our North Louisiana assets.
