Securities	10. Securities On October 25^th, 2013 we invested in three time deposits with total principal of $110,000 Canadian dollars. Our time deposit securities are classified as “held-to-maturity” securities as we have both the intent and ability to hold until maturity. They are carried at cost, adjusted for accrued interest and amortization. The current value is not materially different than fair value. The fair value was determined based on a discounted cash flow analysis using unobservable inputs (i.e. level 3 inputs), which include a forward yield curve, the estimated timing of payments and the credit quality of the underlying creditor. Significant changes in any of the significant unobservable inputs in isolation would not result in a materially lower fair value estimate. The interrelationship between these inputs is insignificant. The U.S. dollar equivalents at April 26, 2014, include $40,775, which is classified as a current asset and will mature within one year, and $58,897, which is classified as a noncurrent asset and will mature within two years.

10. Securities

On October 25^th, 2013 we invested in three time deposits with total principal of $110,000 Canadian dollars. Our time deposit securities are classified as “held-to-maturity” securities as we have both the intent and ability to hold until maturity. They are carried at cost, adjusted for accrued interest and amortization. The current value is not materially different than fair value. The fair value was determined based on a discounted cash flow analysis using unobservable inputs (i.e. level 3 inputs), which include a forward yield curve, the estimated timing of payments and the credit quality of the underlying creditor. Significant changes in any of the significant unobservable inputs in isolation would not result in a materially lower fair value estimate. The interrelationship between these inputs is insignificant. The U.S. dollar equivalents at April 26, 2014, include $40,775, which is classified as a current asset and will mature within one year, and $58,897, which is classified as a noncurrent asset and will mature within two years.
