Basic earnings per share is calculated by dividing the net loss attributable to Alight, Inc. by the weighted average number of shares of Class A Common Stock issued and outstanding for the Successor period. The computation of diluted earnings per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issuance of shares that then would then share in the net income of Alight, Inc. The Company’s Class V Common Stock and Class Z Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities and have not been included in either the basic or diluted earnings per share calculations.

In conjunction with the Business Combination, the Company issued Seller Earnouts contingent consideration, which is payable in the Company’s common stock when the related market conditions are achieved. As the related conditions to pay the consideration had not been satisfied as of the end of the Successor period, the Seller Earnouts were excluded from the diluted earnings per share calculations.

Basic and diluted earnings per share are as follows (in millions, except for share and per share amounts):

	Successor
	Three Months Ended
	September 30,

Basic and diluted net loss per share:

For the Successor three months ended September 30, 2021, 77,459,687 units related to noncontrolling interests, 59,633,274 warrants, and 9,988,297 unvested RSUs, were not included in the computation of diluted shares outstanding as their impact would have been anti-dilutive.

In addition, 14,999,998 shares related to the Seller Earnouts and 16,043,624 unvested PRSUs were excluded from the calculation of basic and diluted earnings per share as the market and performance conditions had not yet been met as of the end of the period.
