Equity

Earnings per share

Basic earnings per share is determined by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is similarly determined, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all dilutive potential common shares had been issued. Dilutive potential common shares consist principally of employee stock options issued by the Company, restricted stock units, and to a lesser extent, certain contingently issuable performance shares. There were 14 million anti-dilutive potential common shares excluded from the reconciliation for the quarter ended March 30, 2019. There were 6 million anti-dilutive potential common shares excluded from the reconciliation for the quarter ended March 31, 2018. Please refer to the Consolidated Statement of Income for basic and diluted earnings per share for the quarters ended March 30, 2019 and March 31, 2018.

Share repurchases

In December 2017, the board of directors approved a new authorization to repurchase up to $1.5 billion of our common stock beginning in January 2018 through December 2019. As of March 30, 2019, $960 million remains available under the authorization.

During the quarter ended March 30, 2019, the Company repurchased approximately 4 million shares of common stock for a total of $220 million. During the quarter ended March 31, 2018, the Company did not repurchase any shares of common stock.

Comprehensive income

Comprehensive income includes net income and all other changes in equity during a period except those resulting from investments by or distributions to shareholders. Other comprehensive income consists of foreign currency translation adjustments, fair value adjustments associated with cash flow hedges and adjustments for net experience losses and prior service cost related to employee benefit plans, net of related tax effects.
