Venezuela's Highly Inflationary Economy [Abstract]
Venezuela's Highly Inflationary Economy	12. VENEZUELA'S HIGHLY INFLATIONARY ECONOMY We operate a small service location in Punta Fijo, Venezuela, whose annual revenues have historically been less than one percent of our consolidated revenues for all periods presented. Because of the uncertain political environment in Venezuela, starting in the third quarter of fiscal year 2010, we began to account for Venezuelan operations pursuant to accounting guidance for designated hyperinflationary economies. Following the designation of the Venezuelan economy as hyperinflationary, we ceased taking the effects of currency fluctuations to accumulated other comprehensive income and began reflecting all effects as a component of other income in our statement of operations. We initially used the parallel exchange rate for Bolivar denominated bonds to translate our Venezuelan operations into U.S. Dollars. This resulted in currency related losses in the third quarter of fiscal year 2010 of $2.1 million. In May 2010, the Venezuelan government took action to close the parallel exchange rate system, precluding its continued use and we subsequently returned to using the Venezuelan central bank's official published rate (5.30 Bolivars per U.S. Dollar) to translate Venezuelan assets into dollars as no other legal rate was readily available. The exchange rate has remained constant since May 2010. Consequently, we recognized no gains or losses for the six months ended November 30, 2011 related to the Venezuelan currency. Due to the uncertain economic and political environment in Venezuela, it is very difficult to repatriate cash flows of these operations. At November 30, 2011, our Venezuelan subsidiary had $2.0 million of net assets, consisting primarily of Bolivar denominated receivables and cash equal to $2.2 million.

We operate a small service location in Punta Fijo, Venezuela, whose annual revenues have historically been less than one percent of our consolidated revenues for all periods presented.
