Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | 11. Derivative Instruments and Foreign Currency Exposure The Company has foreign currency exposure, principally through sales in Canada, Brazil, China, Argentina, Chile and the UK, and production in Brazil, Mexico and China. Management has commenced a derivative instrument program to partially offset this risk by purchasing forward contracts to sell the Canadian Dollar, the Chilean Peso, the Euro, the Great Britain Pound and the Argentina Peso. Such contracts are largely timed to expire with the last day of the fiscal quarter, with a new contract purchased on the first day of the following quarter, to match the operating cycle of the Company. Management has decided not to hedge its long position in the Chinese Yuan. Management previously had not hedged the Brazilian Real, but commenced doing so in May 2012. We designated the forward contracts as nonhedging instruments with loss and gain recognized in the current earnings. In the three and nine-months ended October 31, 2012, the Company sustained a pre-tax gain on foreign exchange in Brazil of $61,791or $0.01 per share and a pre-tax loss of ($840,319) or ($0.13 per share, respectively included in pre-tax income from continuing operations. In the three and nine months ended October 31, 2011, the Company recorded a loss on foreign exchange in Brazil of ($343,803) or ($0.05) per share and ($94,953) or ($0.01) per share, respectively included in pre-tax income from continuing operations. The Company accounts for its foreign exchange derivative instruments as either assets or liabilities at fair value, which may result in additional volatility in both current period earnings and other comprehensive income as a result of recording recognized and unrecognized gains and losses from changes in the fair value of derivative instruments. We also enter cash flow hedge contracts with financial institutions to manage our currency exposure on future cash payments denominated in foreign currencies. The effective portion of gain or loss on cash flow hedge is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings.
