[1] Earnings per share calculations for each quarter include the weighted average effect of stock issuances and common stock equivalents for the quarter; therefore, the sum of quarterly earnings per share amounts may not equal full-year earnings per share amounts, which reflect the weighted average effect on an annual basis. Diluted earnings per share calculations for each quarter include the effect of stock options and non-vested restricted stock units, when dilutive to the quarter. In addition, basic earnings per share and diluted earnings per share may not add due to rounding.
