Change in Fair Value of Embedded Derivative Liability
We recognized a loss of $1.9 million for the three months ended March 31, 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 March 31, 2022. See “Embedded Derivative Liability” in Liquidity and Capital Resources.
Income Tax Benefit
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 expense benefit for the three months ended March 31, 2023 amounted to $2.0 thousand as compared to income tax benefit of $0.7 million for the three months ended March 31, 2022. Our effective tax rates for the three months ended March 31, 2023 and 2022 were (20.0)% and 1.2%, respectively. Our effective tax rate for the three months ended March 31, 2023 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. Our effective rate for the three months ended March 31, 2022 differed from the statutory federal income tax rate primarily due to the impact of the change in valuation allowance on deferred tax assets as well as permanent differences related to the 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 quarter 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 at March 31, 2023 was $22.1 million, consisting of cash on hand of $6.7 million and $15.4 million of availability under our $40.0 million Revolving ABL Credit Facility, based on a borrowing base of $34.2 million.
During the first quarter of 2023, cash flow from operations was positive. On March 31, 2023, we paid in-kind the $11.6 million interest payment due under our Convertible Notes.
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 currently believe that the actions we have taken to date and our existing sources of liquidity are sufficient to fund our operations for at least the next twelve months and periods subsequent to such.
Net Cash Provided by (Used In) Operating Activities
Cash provided by operating activities was $13.6 million for the three months ended March 31, 2023 compared to cash used in operating activities of $1.7 million for the three months ended March 31, 2022. Factors affecting changes in operating cash flows are similar to those that impact net earnings, with the exception of non-cash items such as depreciation and amortization, impairments, gains or losses on disposals of assets, gains or losses on extinguishment of debt, non-cash interest expense, non-cash compensation, deferred taxes, and amortization of debt issuance costs and debt discount. Additionally, changes in working capital items such as accounts receivable, inventory, prepaid expense and accounts payable can significantly affect operating cash flows.
