Explanation of Responses:

( 1 )Each Restricted Stock Unit and Performance Share represented a contingent right to receive one share of SFG stock upon vesting. All Restricted Stock Units and Performance Shares were canceled in the merger of the issuer and a subsidiary of Meiji Yasuda Life Insurance Company (the "Merger") for a cash payment equal to the Merger consideration of $115 per share. ( 2 )Each option, which provided for vesting in four equal annual installments beginning on the date set forth in the Date Exercisable column, was canceled in the Merger in exchange for the cash payment per share indicated in column 8, which represents the difference between the exercise price of the option and the Merger consideration of $115 per share.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
