Change in Fair Value of Embedded Derivative Liability
We recognized a loss of $4.3 million for the nine months ended September 30, 2022 related to the change in fair value of the embedded derivative liability between the issuance date of the Convertible Notes, March 18, 2022, and June 8, 2022. See “Embedded Derivative Liability” in Liquidity and Capital Resources.
Realized Gain on Extinguishment of Derivative
We recognized a gain of $10.8 million for the nine months ended September 30, 2022 related to the extinguishment of the variable component of the PIK interest rate feature of the derivative liability.
Income Tax (Benefit) Expense
Our effective income tax rate fluctuates from the U.S. statutory tax rate based on, among other factors, changes in pretax income in jurisdictions with varying statutory tax rates, the impact of U.S. state and local taxes, the realizability of deferred tax assets and other differences related to the recognition of income and expense between GAAP and tax accounting.
Income tax benefit for the nine months ended September 30, 2023 amounted to $1.0 million as compared to income tax expense of $0.8 million for the nine months ended September 30, 2022. Our effective tax rates for the nine months ended September 30, 2023 and 2022 were 8.2% and (1.2)%, respectively. Our effective tax rate for the nine months ended September 30, 2023 and 2022 differed from the statutory federal income tax rate primarily due to the impact of the change in valuation allowance on deferred tax assets, state taxes, and permanent items related to certain debt items that are expensed for book purposes but are not deductible for tax purposes. The impact of the permanent items related to the debt continues into 2023 but has less of an impact as a significant loss on extinguishment of debt was recorded in 2022.
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized, and when necessary, valuation allowances are recorded. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We assess the realizability of our deferred tax assets quarterly and consider carryback availability, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. In the first nine months of 2023, the effective tax rate takes into consideration the estimated valuation allowance based on forecasted 2023 income.
We continue to monitor income tax developments in the United States. We will incorporate into our future financial statements the impacts, if any, of future regulations and additional authoritative guidance when finalized.
Liquidity and Capital Resources
Our liquidity as of September 30, 2023 was $19.1 million, consisting of cash on hand of $6.0 million and $15.7 million of availability under our $40.0 million Revolving ABL Credit Facility, based on a borrowing base of $20.9 million.
During the first nine months of 2023, cash flow from operations was positive. On March 31, 2023 and September 30, 2023, we paid in-kind the $11.6 million and $12.4 million interest payment due under our Convertible Notes, respectively. On June 30, 2023 and September 30, 2023, our noteholders accepted our mandatory offer to redeem $5.0 million and $5.0 million, respectively, of Convertible Notes plus accrued interest. As a result, on June 30, 2023, we paid $5.0 million principal and $0.2 million in accrued interest in cash, and on September 30, 2023, we paid $5.0 million principal and $0.4 million in accrued interest in cash. We funded these redemptions through borrowings under our Revolving ABL Credit Facility.
We expect our future capital and liquidity needs to be related to operating expenses, maintenance capital expenditures, and working capital and general corporate purposes.
We believe that our cash and cash equivalents, cash flows from operating activities and borrowings under our Revolving Credit Facility will adequately finance all of our anticipated purchase commitments, capital expenditures and other cash requirements over the next twelve months from issuance.
