(1) | During 2012, we issued $126.5 million of 1.875% convertible senior notes convertible into shares of our common stock at a rate of 17.1985 shares per 1,000 principle amount. In accordance with ASC 260-10, Earnings Per Share, ("ASC 260-10") we calculate the dilutive effect of convertible securities using the "if-converted" method.
(2) | For periods with a net loss, no options or non-vested shares are included in the dilution calculation as all options and non-vested shares outstanding are considered anti-dilutive.
