(1)	The denominator does not include stock equivalents for options issued under the non-qualified stock option plan due to conversion prices being higher than market prices for all periods. If the conditions for conversion were met under this plan, 466,183 and 581,757 shares would be included for the three months ended March 31, 2012 and 2011, respectively.
