For the three months ended March 31, 2022, we recorded a current tax expense of $5.0 million compared to nil tax expense recorded for the same period in 2021. Current tax consists of U.S. federal and state tax as a result of higher net income
in 2022 as we could potentially utilize the full amount of our net operating loss carryforwards in 2022. Many factors influence taxable income including future commodity prices, production levels, development activities, capital spending, and overall profitability. As a result of the higher commodity prices, we are updating our current tax guidance from $10.0 million to $20.0 million – $30.0 million (2% – 3% of adjusted funds flow before tax) for 2022 assuming WTI of $85.00/bbl and NYMEX of $5.00/Mcf.
For the three months ended March 31, 2022, we recorded a deferred income tax expense of $9.8 million, compared to an expense of $8.7 million for the same period in 2021.
We assess the recoverability of our deferred income tax assets each period to determine whether it is more likely than not all or a portion of our deferred income tax assets will not be realized. We have considered available positive and negative evidence including future taxable income and reversing existing temporary differences in making this assessment. This assessment is primarily the result of projecting future taxable income using total proved and probable forecast average prices and costs. There is risk of a valuation allowance in future periods if commodity prices weaken or other evidence indicates that some of our deferred income tax assets will not be realized. See “Risk Factors and Risk Management – Risk of Impairment of Oil and Gas Properties and Deferred Tax Assets” in the Annual MD&A. For the three months ended March 31, 2022, no valuation allowance was recorded against our U.S. and Canadian income related deferred tax assets, however, a full valuation allowance has been recorded against our deferred income tax assets related to capital items. Our overall net deferred income tax asset is $374.2 million at March 31, 2022 (December 31, 2021 - $380.9 million).
LIQUIDITY AND CAPITAL RESOURCES
There are numerous factors that influence how we assess liquidity and leverage, including commodity price cycles, capital spending levels, acquisition and divestment plans, commodity derivative contracts, share repurchases and dividend levels. We also assess our leverage relative to our most restrictive debt covenant, which is a maximum senior debt to earnings before interest, taxes, depreciation, amortization, impairment and other non-cash charges (“adjusted EBITDA”) ratio of 3.5x for a period of up to six months, after which it drops to 3.0x. At March 31, 2022, our senior debt to adjusted EBITDA ratio was 0.7x and our net debt to adjusted funds flow ratio1 was 0.7x. Although a non-GAAP measure that is not included in our debt covenants, the net debt to adjusted funds flow ratio is often used by investors and analysts to evaluate liquidity. Refer to the definitions and footnotes below.
Net debt at March 31, 2022 decreased to $572.3 million, compared to $640.4 million at December 31, 2021. Total debt was comprised of our senior notes, and Bank Credit Facilities, totaling $595.0 million, less cash on hand of $22.7 million. During the quarter, we converted our senior unsecured, covenant-based $400 million term loan maturing on March 9, 2024 into a revolving bank credit facility with no other amendments.
At March 31, 2022 through our Bank Credit Facilities, we had total credit capacity of $1.3 billion, of which $293.0 million was drawn. We expect to finance our working capital requirements and upcoming senior note repayments through cash, adjusted funds flow and our credit capacity. We have sufficient liquidity to meet our financial commitments for the near term.
Our reinvestment rate1 was 38% for the three months ended March 31, 2022 compared to 51% for the same period in 2021. We are committed to free cash flow generation and are targeting a long-term capital spending reinvestment rate1 of less than 75% of annual adjusted funds flow1.
During the first quarter of 2022, a total of $45.1 million was returned to shareholders through share repurchases and dividends, compared to $5.6 million for the same period in 2021. A total of 3,134,700 common shares were repurchased and cancelled under the Normal Course Issuer Bid (“NCIB”) at an average price of $11.87 per share, for total consideration of $37.2 million. We did not have a NCIB in place during the three months ended March 31, 2021. Subsequent to March 31, 2022 and up to and including May 4, 2022, we repurchased 1,494,996 common shares under the NCIB at an average price of $12.61 per share, for total consideration of $18.9 million.
