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 December 31, 2022, the estimated purchase amount we would be contingently liable for was approximately $357.0 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.
On August 20, 2021, one of our wholly owned subsidiaries acquired MIS, a distributor of air conditioning and heating products operating from six locations in Pennsylvania.

Consideration for the purchase consisted of $18.1 million in cash, 8,492 shares of Common stock having a fair value of $2.6 million, and $3.1 million repayment of indebtedness, net of cash acquired of $1.3 million.
On April 9, 2021, we acquired certain assets and assumed certain liabilities comprising the HVAC distribution business of Temperature Equipment Corporation, an HVAC distributor operating from 32 locations in Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, and Wisconsin. We formed a new, stand-alone joint venture with Carrier, TEC, which operates this business. We have an 80% controlling interest in TEC, and Carrier has a 20%
non-controlling
interest. Consideration for the purchase was paid in cash, consisting of $105.2 million paid to Temperature Equipment Corporation (Carrier contributed $21.0 million and we contributed $84.2 million) and $1.5 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.
We paid cash dividends of $8.55, $7.625, and $6.925 per share of Common stock and Class B common stock in 2022, 2021, and 2020, respectively. On January 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 January 31, 2023 to shareholders of record as of January 17, 2023. Future dividends and/or 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.
Company Share Repurchase Program
In September 1999, our Board of Directors authorized the repurchase, at management’s discretion, of up to 7,500,000 shares of common stock in the open market or via private transactions. Shares repurchased under the program are accounted for using the cost method and result in a reduction of shareholders’ equity. We last repurchased shares under this plan in 2008. In aggregate, 6,370,913 shares of Common and Class B common stock have been repurchased at a cost of $114.4 million since the inception of the program. At December 31, 2022, there were 1,129,087 shares remaining authorized for repurchase under the program. The IRA includes, among other provisions, a 1% excise tax on corporate stock repurchases in tax years beginning after December 31, 2022. In consideration of any further stock repurchases under our repurchase program, we intend to evaluate the impact of the IRA’s 1% excise tax on stock repurchases in tax years beginning after December 31, 2022.
Quantitative and Qualitative Disclosures About Market Risk

We use derivative instruments as risk management tools and not for trading purposes.
Foreign Currency Exposure
We are exposed to cash flow and earnings fluctuations resulting from currency exchange rate variations. These exposures are transactional and translational in nature.
