Goodwill [Abstract]
GOODWILL	6. GOODWILL Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment on an annual basis and between annual tests in certain circumstances. The performance of the goodwill impairment test involves a two-step process. The first step involves comparing the fair value of our reporting units to their carrying values, including goodwill. We determine fair value based on estimated future cash flows of each reporting unit discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. The cash flow projections for each reporting unit are based on a five-year forecast of cash flows, derived from the most recent annual financial forecast. If the carrying value of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. As of July 31, 2011, we determined that the fair value of the goodwill we recorded in connection with our acquisition of Adisn in the amount of $4,360,176 exceeded its carrying value and therefore goodwill was not impaired.
