(1) The fair value of the contingent earnout of acquired businesses was determined using a mark-to-market modeling technique based on significant unobservable inputs calculated using a discounted future cash flows approach. Key assumptions include a discount rate of 41.2% and annual revenues of acquired businesses ranging from $1.5 million to $6.1 million over the life of the earnout. On July 31, 2012, the contingent earnout was reassessed and, based on our estimates of the likelihood of future revenues subject to the earnout provisions, assigned no value. Our conclusions have not changed since that time.
