service, repayment and other financing costs of our borrowings, (iv) funding repurchases under our Share Repurchase Program and (v) cash distributions to the holders of our shares.
As of March 31, 2022 and December 31, 2021, we had twelve and twelve asset based leverage facilities, one and one revolving credit facility, ten and seven unsecured note issuances, four and three debt securitizations and short term borrowings related to repurchase obligations outstanding, respectively. We have and will continue to, from time to time, enter into additional credit facilities, increase the size of our existing credit facilities or issue additional debt securities, including debt securitizations, unsecured debt, interest rate swaps and other forms of debt. Any such incurrence or issuance may be from sources within the U.S. or from various foreign geographies or jurisdictions, and may be denominated in currencies other than the U.S. Dollar. Additionally, any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to incur borrowings, issue debt securities or issue preferred stock, if immediately after the borrowing or issuance, the ratio of total assets (less total liabilities other than indebtedness) to total indebtedness plus preferred stock, is at least 150%. As of March 31, 2022 and December 31, 2021, we had an aggregate amount of $19,205.8 million and $18,301.5 million, respectively, of debt securities outstanding and our asset coverage ratio was 193.4% and 170.2%.
Cash and cash equivalents as of March 31, 2022, taken together with our $8,241.0 million of available capacity under our credit facilities (subject to borrowing base availability), proceeds from new or amended financing arrangements and the continuous offering of our common shares is expected to be sufficient for our investing activities and to conduct our operations in the near term. This determination is based in part on our expectations for the timing of funding investment purchases and the timing and amount of future proceeds from sales of our common shares and the use of existing and future financing arrangements. As of March 31, 2022, we had significant amounts payable and commitments for new investments, which we planned to fund using proceeds from offering our common shares and available borrowing capacity under our credit facilities. Additionally, we held $9,508.5 million of Level 2 debt investments as of March 31, 2022, which could provide additional liquidity if necessary.
Although we were able to issue several new unsecured notes and a debt securitization during the three months ended March 31, 2022 and the financial markets have recovered from 2020 levels, another disruption in the financial markets caused by the COVID-19 outbreak, geopolitical uncertainties or any other negative economic development could restrict our access to financing in the future. We may not be able to find new financing for future investments or liquidity needs and, even if we are able to obtain such financing, such financing may not be on as favorable terms as we could have obtained prior to the outbreak of the pandemic. These factors may limit our ability to make new investments and adversely impact our results of operations.
As of March 31, 2022, we had $1,643.0 million in cash and cash equivalents. During the three months ended March 31, 2022, cash used in operating activities was $4,701.7 million, primarily as a result of funding portfolio investments of $7,816.6 million, partially offset by proceeds from sale of investments of $789.2 million and an increase in payables for investments purchases of $2,037.1 million. Cash provided by financing activities was $5,726.7 million during the period, primarily as a result of new share issuances related $5,022.2 million of subscriptions and net borrowings of $890.5 million.
As of March 31, 2021, we had $119.3 million in cash and cash equivalents. During the three months ended March 31, 2021, cash used in operating activities was $3,400.0 million, primarily as a result of funding portfolio investments of $4,316.5 million, the acquisition of Twin Peaks for $697.4 million (net of cash assumed), partially offset by an increase in net payables for investments purchases of $1,404.3 million. Cash provided by financing activities was $3,519.3 million during the period, primarily as a result of new share issuances related $2,085.7 million of subscriptions and net borrowings on our credit facilities $1,451.8 million.
