(1) A total of 1.3 million and 1.0 million stock-based awards were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2016 and 2015, respectively, as their effect would be anti-dilutive.

(2) Contingent shares represent additional shares to be issued for purchase price earned by former owners of businesses acquired by CBIZ.

(3) The dilutive impact of potential shares to be issued upon conversion of the 2010 Notes is not applicable to the three months ended March 31, 2016 due to the maturation of the 2010 Notes in the fourth quarter of 2015.
