(15) EARNINGS (LOSS) PER SHARE

Basic earnings per share of Premier is computed by dividing net income attributable to stockholders by the weighted average number of shares of common stock outstanding for the period. Net income attributable to stockholders includes the adjustment recorded in the period to reflect redeemable limited partners' capital at the redemption amount, as a result of the exchange benefit obtained by limited partners through the ownership of Class B common units. Except when the effect would be anti-dilutive, the diluted earnings (loss) per share calculation, which is calculated using the treasury stock method, includes the impact of shares that could be issued under the outstanding stock options, non-vested restricted stock units and awards, shares of non-vested performance share awards and the effect of the assumed redemption of Class B common units through the issuance of Class A common shares.

The following table provides a reconciliation of the numerator and denominator used for basic and diluted earnings (loss) per share (in thousands, except per share amounts):
