Net Income Per Share Attributable to Lear

Basic net income per share available to Lear common stockholders is computed using the two-class method by dividing net income attributable to Lear, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding during the period. Common shares issuable upon the satisfaction of certain conditions pursuant to a contractual agreement are considered common shares outstanding and are included in the computation of basic net income per share available to Lear common stockholders.
