Treasury Stock Transactions

During the second quarter of 2019, our board of directors authorized the repurchase of up to $750.0 million of Unum Group's outstanding common stock through November 23, 2020. This authorization replaced the previous authorization of $750.0 million that was scheduled to expire on November 24, 2019. The remaining repurchase amount under the new program was $616.2 million at September 30, 2019.
