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 nine months, after which it drops to 3.0x. At September 30, 2022, our senior debt to adjusted EBITDA ratio was 0.4x and our net debt to adjusted funds flow ratio was 0.3x. Although a capital management 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.
Net debt at September 30, 2022 decreased to $391.1 million, compared to $640.4 million at December 31, 2021. Total debt was comprised of our senior notes and Bank Credit Facilities, totaling $433.2 million, less cash on hand of $42.2 million.
At September 30, 2022, through our Bank Credit Facilities, we had total credit capacity of $1.3 billion, of which $230.0 million was drawn. We expect to finance our working capital requirements through cash, adjusted funds flow and our credit capacity. We have sufficient liquidity to meet our financial commitments for the near term.
Subsequent to the quarter, on November 3, 2022, Enerplus converted its $400 million revolving bank credit facility to a $365 million SLL bank credit facility, and extended the maturity to October 31, 2025. The $365 million SLL bank credit facility has similar targets to Enerplus’ $900 million SLL bank credit facility, which was renewed with $50 million maturing on October 31, 2025, and $850 million maturing on October 31, 2026. There were no other significant amendments or additions to the two agreements’ terms or covenants.
Our reinvestment rate1 was 32% and 38% for the three and nine months ended September 30, 2022, respectively, compared to 31% and 49%, respectively, for the same periods in 2021.
During the three and nine months ended September 30, 2022, a total of $123.3 million and $271.3 million, respectively, was returned to shareholders through share repurchases and dividends, compared to $18.1 million and $32.8 million for the same periods in 2021. During the third quarter of 2022, we announced our intention to increase our expected 2022 return of capital to at least 60% of free cash flow1 commencing in the second half of 2022 and continuing through 2023, an increase from 50% of free cash flow in the first half of 2022. We also previously announced an increase to the expected minimum return of capital level to $425 million for 2022. Subsequent to the quarter, the Board of Directors approved a 10% increase to the quarterly dividend to $0.055 per share, from $0.050 per share, beginning December 2022. We expect to fund the dividend and share repurchases through the free cash flow generated by the business.
During the three months ended September 30, 2022, a total of 7,913,168 common shares were repurchased and cancelled under the Normal Course Issuer Bid (“NCIB”) at an average price of $14.13 per share, for total consideration of $111.8 million. During the nine months ended September 30, 2022, a total of 18,126,090 common shares were repurchased and cancelled under the NCIB at an average price of $13.35 per share, for total consideration of $241.9 million. During the three and nine months ended September 30, 2021, 1,657,650 common shares were repurchased and cancelled under the NCIB at an average price of $6.12 per share, for total consideration of $10.1 million.
At September 30, 2022, we were in compliance with all covenants under the Bank Credit Facilities and outstanding senior notes. If we exceed or anticipate exceeding our covenants, we may be required to repay, refinance or renegotiate the terms of the debt. See "Risk Factors – Debt covenants of the Corporation may be exceeded with no ability to negotiate covenant relief" in the Annual Information Form.
