| CHANGES IN ESTIMATE - LEGACY WASTE ACCRUAL - PERMA-FIX NORTHWEST, INC. (PFNW) AND PERMA-FIX NORTHWEST RICHLAND, INC (PFNWR) | NOTE 8 CHANGES IN ESTIMATE – LEGACY WASTE ACCRUAL – PERMA-FIX NORTHWEST, INC. (“PFNW') AND PERMA-FIX NORTHWEST RICHLAND, INC (“PFNWR”) In acquiring PFNWR and PFNW in June 2007, the Company allocated the cost of the acquisition to the specific tangible and intangible assets acquired and liabilities assumed based upon their fair values at the date of acquisition. Judgment and estimates were made to determine these values using the most readily available information at the time of acquisition. In 2008, the Company finalized the cost of the acquisition to the assets acquired and liabilities assumed. Adjustments to assets acquired or liabilities assumed during the purchase allocation period, which is generally one year, were recorded to goodwill. During the third quarter of 2009, as a result of a change in estimate related to accrued costs to dispose of legacy waste that were assumed as part of our acquisition of PFNWR and PFNW in June 2007, we reduced our disposal/transportation accrual by approximately $787,000 which was recorded as a reduction to our disposal/transportation expense in our cost of goods sold. The change in estimate was necessary due to our accumulation of new information that had resulted in our identifying more efficient and cost effective ways to dispose of this legacy waste. |
