[1] The Company assesses the estimated fair value of the contingent obligation on a quarterly basis using a probability weighted income approach (discounted cash flow) valuation technique. When preparing discounted cash flow models under the income approach, the Company uses internal forecasts to estimate future cash flows. The Companys internal forecasts are developed using observable (Level 2) and unobservable (Level 3) inputs. For the three months ended March 31, 2013, the Company measured the fair value of its contingent obligation and recorded a non-cash gain fair value adjustment of approximately $0.2 million to reflect a reduction in fair value of its contingent obligation. The principal factor affecting the reduction in fair value is a change in timing of expected revenues due to client implementation delays. There were no significant changes in discount rate used in the calculation of fair value. There were changes in probability payout weightings used in the calculation to account for client implementation delays. The potential payout of consideration for the year ending 2013 is up to $1.5 million of face value of the contingent obligation.
