Schedule of Fair Value Option Award Weighted Average Assumptions Used

The following weighted average assumptions were utilized:

	2014			2013			2012
Expected volatility (1)		28.83	%		33.46	%		32.86	%
Expected option life (years) (2)		4.66			4.85			4.85
Risk-free interest rate (3)		1.38	%		0.75	%		0.78	%
Expected dividend yield (4)		0.00	%		0.00	%		0.00	%

(1) The expected volatility assumption was determined based upon the historical volatility of CBIZ’s stock price, using daily price intervals.

(2) The expected option life was determined based upon CBIZ’s historical data using a midpoint scenario, which assumes all options are exercised halfway between the expiration date and the weighted average time it takes the option to vest.

(3) The risk-free interest rate assumption was based upon zero-coupon U.S. Treasury bonds with a term approximating the expected life of the respective options.

(4) The expected dividend yield assumption was determined in view of CBIZ’s historical and estimated dividend payouts. CBIZ does not expect to change its dividend payout policy in the foreseeable future.
