Equity [Abstract] |
Equity | Equity Preferred Stock We have 5,000,000 shares of preferred stock authorized, with no par value, of which (i) 300,000 shares are designated Series A junior preferred stock, which have not been issued, and (ii) 8,000 shares were issued as Series B in 2020 as discussed below. On December 2, 2020, we issued 8 million depository shares, each representing a 1/1,000th interest in a share of our perpetual 4.60% Non-Cumulative Preferred Stock, Series B, without par value, with a liquidation preference of $25,000 per share (equivalent to $25.00 per depository share) (“Preferred Stock”), for net proceeds of $194.6 million. Dividends are recorded when declared and, if declared, are payable quarterly in arrears on the 15th day of March, June, September, and December. If a dividend is not declared and paid or made payable on all outstanding shares of the Preferred Stock for the latest completed dividend period, no dividends may be declared or paid on our common stock and we may not purchase, redeem, or otherwise acquire our outstanding common stock. The Preferred Stock is redeemable at our option in whole or in part, from time to time, on or after December 15, 2025 at a redemption price equal to $25,000 per share of Preferred Stock (equivalent to $25.00 per depository share), plus unpaid dividends attributable to the then current dividend period. Prior to December 15, 2025, the Preferred Stock is redeemable at the Company’s option, in whole but not in part, within 90 days of the occurrence of (a) a rating agency event at a redemption price equal to $25,500 per share of Preferred Stock (equivalent to $25.50 per depository share), plus unpaid dividends attributable to the current dividend period in circumstances where a rating agency changes its criteria used to assign equity credit to securities like the Preferred Stock; or (b) a regulatory capital event at a redemption price equal to $25,000 per share of Preferred Stock (equivalent to $25.00 per depository share), plus unpaid dividends attributable to the current dividend period in circumstances where a capital regulator such as a state insurance regulator changes or proposes to change capital adequacy rules. Share Repurchase Program On December 2, 2020, we announced that our Board authorized a $100 million share repurchase program, with no set expiration or termination date. Our repurchase program does not obligate us to acquire any particular amount of our common stock. Management will determine the timing and amount of any share repurchases under the authorization at its discretion based on market conditions and other considerations. For the year ended December 31, 2024, 103,000 shares were repurchased under the share repurchase program for a total cost of $8.7 million, including commissions. We had no common stock share repurchases in 2023. As of December 31, 2024 and December 31, 2023, we had $75.5 million and $84.2 million of remaining capacity under our share repurchase program, respectively.
