1For the three months ended March 31, 2025, includes 0.7 million shares related to the settlement of the November 2024 accelerated share repurchase agreement (ASR) which occurred in February 2025.
2Includes $0.5 million and a de minimis amount of commissions for the three months ended March 31, 2025 and 2024, respectively. Also includes $2.1 million and $1.1 million of excise taxes for the three months ended March 31, 2025 and 2024, respectively.

As a part of our share repurchase program, we periodically enter into accelerated share repurchase agreements. Under the terms of these agreements, we make a prepayment to a financial counterparty for which we receive an initial delivery of approximately 75 percent of the total Unum Group common stock to be delivered under the agreement. We simultaneously enter into a forward contract indexed to the price of Unum Group common stock, which subjects the transactions to a future price adjustment. Under the terms of the agreements, we are to receive, or be required to pay, a price adjustment based on the volume weighted average price of Unum Group common stock during the term of the agreement, less a discount. Any price adjustment payable to us is settled in shares of Unum Group common stock. Any price adjustment we would be required to pay may be settled in either cash or common stock at our option. Details of our ASRs impacting the three months ended March 31, 2025 and 2024 are as follows:

1The final price adjustment settlement, along with the delivery of the remaining shares, occurred in February 2025, resulting in the delivery to us of 0.7 million additional shares. As a result of the final settlement occurring subsequent to December 31, 2024, we recorded a decrease of $80.3 million to additional paid-in capital within stockholders' equity on our consolidated balance sheet for the value of the shares held back by the counterparty as of December 31, 2024, which was reclassified to treasury stock in the first quarter of 2025 in connection with the final settlement of the agreement.
