Earnings Per Share Disclosure

Earnings Per Common Share

Net income per common share is determined as follows:

	Year Ended December 31
	2021		2020		2019
	(in millions of dollars, except share data)
Numerator
Net Income	$	824.2	$	793.0	$	1,100.3
Denominator (000s)
Weighted Average Common Shares - Basic	204,232.9		203,642.0		209,728.9
Dilution for Assumed Exercises of Stock Options and Nonvested Stock Awards	615.0		113.3		125.5
Weighted Average Common Shares - Assuming Dilution	204,847.9		203,755.3		209,854.4
Net Income Per Common Share
Basic	$	4.04	$	3.89	$	5.25
Assuming Dilution	$	4.02	$	3.89	$	5.24

We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. In computing earnings per share assuming dilution, we include potential common shares that are dilutive (those that

reduce earnings per share). We use the treasury stock method to account for the effect of outstanding stock options, nonvested stock success units, nonvested restricted stock units, and nonvested performance share units on the computation of diluted earnings per share. Under this method, the potential common shares from stock options, nonvested stock success units, and nonvested restricted stock units will each have a dilutive effect, as individually measured, when the average market price of Unum Group common stock during the period exceeds the exercise price of the stock options and the grant price of the nonvested stock success units and nonvested restricted stock units. Potential common shares from performance based share units will have a dilutive effect as the attainment of performance conditions is progressively achieved during the vesting period. Potential common shares not included in the computation of diluted earnings per share because the impact would be antidilutive, approximated 1.1 million, 1.6 million, and 1.1 million for the years ended December 31, 2021, 2020, and 2019, respectively. See Note 11 for further discussion of our stock-based compensation plans.

In November 2021, we entered into an accelerated repurchase agreement with a financial counterparty to repurchase $50.0 million of Unum Group's common stock in aggregate. As part of this transaction, we paid $50.0 million to the financial counterparty and received an initial delivery of 1.4 million shares of our common stock, which represented approximately 75 percent of the total delivery under the agreement. We simultaneously entered into a forward contract indexed to the price of Unum Group common stock, which subjected the transaction to a future price adjustment. Under the terms of the repurchase agreement, we were 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 was to be settled in shares of Unum Group common stock. Any price adjustment we would have been required to pay would have been settled in either cash or common stock at our option. The final price adjustment settlement, along with the delivery of the remaining shares, also occurred in November 2021, resulting in the delivery to us of 0.5 million additional shares. In total, we repurchased 1.9 million shares pursuant to the accelerated repurchase agreement.

Preferred Stock

Unum Group has 25.0 million shares of preferred stock authorized with a par value of $0.10 per share. No preferred stock has been issued to date.
