Liquidity and Capital Resources
Our liquidity as of June 30, 2024 was $21.0 million, consisting of cash on hand of $5.5 million and $15.5 million of availability under our $40.0 million Revolving ABL Credit Facility, based on a borrowing base of $25.4 million.
During the second quarter of 2024, cash flow from operations was positive. On March 31, 2024, we paid in-kind the $13.3 million interest payment due under our Convertible Notes. On March 31, 2024 and June 30, 2024, our noteholders accepted our mandatory offer to redeem $3.5 million and $3.5 million, respectively, of Convertible Notes plus accrued interest. As a result, on March 31, 2024, we paid $3.5 million principal and $0.3 million in accrued interest in cash and on June 30, 2024, we paid $3.5 million principal and $0.2 million in accrued interest in cash. We funded the redemption through borrowings under our Revolving ABL Credit Facility. Looking forward, we have elected to pay in-kind interest under our Convertible Notes that is due and payable on September 30, 2024.
We expect our future capital and liquidity needs to be related to operating expenses, maintenance capital expenditures, payment of mandatory offer obligations on our Convertible Notes, working capital investments and general corporate purposes. As of June 30, 2024, our net working capital was $10.0 million. This amount excludes outstanding borrowings under our revolving credit facility of $9.8 million as well as future mandatory offer obligations through March 31, 2025 of $10.5 million, which we intend to finance through borrowings under our revolving credit facility. Our revolving credit facility matures on September 30, 2025, therefore, beginning September 30, 2024, borrowings under our revolving credit facility, and related mandatory offer obligations, will be reported as current liabilities and reduce net working capital accordingly. In order to fund these obligations, we currently expect to pay interest in-kind under its Convertible Notes until they mature on March 18, 2026. As a result, even after taking into consideration mandatory offer payments of principal, we expect that the face amount outstanding under our Convertible Notes to continue to increase through maturity.
We believe that our cash and cash equivalents, cash flows from operating activities and borrowings under our Revolving Credit Facility and ability to pay interest in-kind under our Convertible Notes are adequate for us to finance all of our anticipated purchase commitments, mandatory offer obligations, capital expenditures and other cash requirements over the next twelve months.
