Borrowings under the revolving credit facility bear interest at either Term SOFR or Daily Simple SOFR-based rates plus 0.10%, plus a spread which ranges from 100.0 to 137.5 basis-points (Term SOFR and Daily Simple SOFR plus 100.0 basis-points at March 31, 2023), depending on our ratio of total debt to EBITDA, or on rates based on the highest of the Federal Funds Effective Rate plus 0.5%, the Prime Rate or Term SOFR plus 1.0%, in each case plus a spread which ranges from 0 to 50.0 basis-points (0 basis-points at March 31, 2023), depending on our ratio of total debt to EBITDA. We pay a variable commitment fee on the unused portion of the commitment under the revolving credit agreement, ranging from 12.5 to 27.5 basis-points (12.5 basis-points at March 31, 2023). We paid fees of $0.6 million in connection with entering into the revolving credit agreement, which are being amortized ratably through the maturity of the facility in March 2028.
At March 31, 2023, $197.6 million was outstanding under the revolving credit agreement. The revolving credit agreement contains customary affirmative and negative covenants, including financial covenants with respect to consolidated leverage and interest coverage ratios, and other customary restrictions. We believe we were in compliance with all covenants at March 31, 2023.
At-the-Market Offering Program
On February 25, 2022, we entered into an amended and restated sales agreement with Robert W. Baird & Co. Inc. and Goldman Sachs & Co. LLC, which enables the Company to issue and sell shares of Common stock in one or more negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), for a maximum aggregate offering amount of up to $300.0 million (the “ATM Program”). The offer and sale of our Common stock pursuant to the ATM Program has been registered under the Securities Act pursuant to our automatically effective shelf registration statement on Form S-3 (File No. 333-260758). As of March 31, 2023, no shares of Common stock had been sold under the ATM Program.
Investment in Unconsolidated Entity
Carrier Enterprise I, one of our joint ventures with Carrier, in which we have an 80% controlling interest, has a 38.1% ownership interest in RSI, an HVAC distributor operating from 35 locations in the Western U.S. Our proportionate share of the net income of RSI is included in other income in our condensed consolidated unaudited statements of income.
Carrier Enterprise I is a party to a shareholders’ agreement (the “Shareholders’ Agreement”) with RSI and its shareholders, consisting of five family siblings, their children and affiliates related to them. Pursuant to the Shareholders’ Agreement, RSI’s shareholders have the right to sell, and Carrier Enterprise I has the obligation to purchase, their respective shares of RSI for a purchase price determined based on the higher of book value or a multiple of EBIT, the latter of which Carrier Enterprise I used to calculate the price for its 38.1% investment held in RSI. RSI’s shareholders may transfer their respective shares of RSI common stock only to members of the Sigler family or to Carrier Enterprise I, and, at any time from and after the date on which Carrier Enterprise I owns 85% or more of RSI’s outstanding common stock, it has the right, but not the obligation, to purchase from RSI’s shareholders the remaining outstanding shares of RSI common stock. At March 31, 2023, the estimated purchase amount we would be contingently liable for was approximately $356.0 million. We believe that our operating cash flows, cash on hand, funds available for borrowing under our revolving credit agreement, or use of the ATM Program would be sufficient to purchase any additional ownership interests in RSI.
Acquisitions
On March 3, 2023, one of our wholly owned subsidiaries acquired Capitol, a distributor of air conditioning and heating products with annual sales of approximately $13.0 million, operating from three locations in New York. Consideration for the purchase consisted of $1.3 million in cash, net of cash acquired of $0.1 million, and $1.8 million for repayment of indebtedness.
We continually evaluate potential acquisitions and/or joint ventures and investments in unconsolidated entities. We routinely hold discussions with several acquisition candidates. Should suitable acquisition opportunities arise that would require additional financing, we believe our financial position and earnings history provide a sufficient basis for us to either obtain additional debt financing at competitive rates and on reasonable terms or raise capital through the issuance of equity securities.
Common Stock Dividends
We paid cash dividends of $2.45 and $1.95 per share on Common and Class B common stock during the quarters ended March 31, 2023 and 2022, respectively. On April 3, 2023, our Board of Directors declared a regular quarterly cash dividend of $2.45 per share of both Common and Class B common stock that was paid on April 28, 2023 to shareholders of record as of April 17, 2023. Future dividends and changes in dividend rates are at the sole discretion of the Board of Directors and depend upon factors including, but not limited to, cash flow generated by operations, profitability, financial condition, cash requirements, and future prospects.
