REVISIONS [Abstract]
REVISIONS	NOTE B –REVISIONS During the year ended December 31, 2011, we determined that $4.2 million of mutual funds should be classified as Marketable Securities. Previously, such investments were classified as cash and cash equivalents. Accordingly, we revised the prior year classification to exclude from cash and cash equivalents $4.2 million of mutual funds at December 31, 2010 and 2009, respectively, and to classify such amounts as Marketable Securities. In addition, we have made corresponding adjustments to the accompanying statements of cash flows to reflect the gross purchases and sales of these securities as investing activities for the year ended December 31, 2009. As a result, cash used in investing activities increased by $70,000 and $4.2 million for the years ended December 31, 2010 and 2009, respectively. This revision does not affect previously reported cash flows from operating or from financing activities. Certain amounts have also been revised within our financial statements as of December 31, 2010 to correct for items that were not appropriately classified within the balance sheet. The net impact of these changes included a $3.4 million increase to Total Current Assets, a $4.3 million decrease to Other Assets, a $762,000 increase to Total Current Liabilities and a $1.7 million decrease to Other Long-Term Liabilities. These revisions do not affect previously reported cash flows from operating or financing activities, as well as previously reported cash used in investing activities. These revisions do not impact our previously reported results from operations. Management concluded that these revisions, both individually and in the aggregate, were not material to the previously issued financial statements but nonetheless revised the 2010 and 2009 financial statements for consistency with the 2011 presentation.

NOTE B –REVISIONS

During the year ended December 31, 2011, we determined that $4.2 million of mutual funds should be classified as Marketable Securities. Previously, such investments were classified as cash and cash equivalents. Accordingly, we revised the prior year classification to exclude from cash and cash equivalents $4.2 million of mutual funds at December 31, 2010 and 2009, respectively, and to classify such amounts as Marketable Securities. In addition, we have made corresponding adjustments to the accompanying statements of cash flows to reflect the gross purchases and sales of these securities as investing activities for the year ended December 31, 2009. As a result, cash used in investing activities increased by $70,000 and $4.2 million for the years ended December 31, 2010 and 2009, respectively. This revision does not affect previously reported cash flows from operating or from financing activities.

Certain amounts have also been revised within our financial statements as of December 31, 2010 to correct for items that were not appropriately classified within the balance sheet. The net impact of these changes included a $3.4 million increase to Total Current Assets, a $4.3 million decrease to Other Assets, a $762,000 increase to Total Current Liabilities and a $1.7 million decrease to Other Long-Term Liabilities. These revisions do not affect previously reported cash flows from operating or financing activities, as well as previously reported cash used in investing activities.
