[1] The diluted weighted average number of shares of common stock outstanding did not differ from the basic weighted average number of shares of common stock outstanding because the effects of any potential common stock equivalents (see Note 5 for further details on outstanding stock options and unvested restricted stock units) were anti-dilutive and therefore not included in the calculation of the denominator of dilutive earnings per share.
