(1)The contingent consideration represents the estimated fair value of the potential contingent consideration opportunity payable in connection with the De Novo acquisition that is contingent upon achieving performance hurdles based on operating revenue objectives. The carrying value at December 31, 2011, was based on management’s estimate of projected revenue over the measurement period as well as the probability of contingent consideration achievement. We applied a discount rate to the projected contingent consideration payments that approximated the weighted average cost of capital. As discussed in Note 3 the carrying value was adjusted to zero during the third quarter of 2012.
