Investments [Abstract]
Investment, Policy [Policy Text Block]	For the available-for-sale bonds and term notes, the carrying value equals the fair value. Held-to-maturity investments were primarily corporate bonds, municipal bonds and municipal term notes and were held at amortized cost, which approximated fair value. Long-term investments have maturities longer than one year but shorter than three years. The Company accounts for its purchases and sales of investments on the trade date of the investment. Change in Investment Classification- During the first quarter of fiscal 2015, the Company liquidated investments classified as held-to-maturity. As a result of the sale of held-to-maturity investments, the Company transferred its entire portfolio to the available-for-sale classification at fair value at the date of transfer. The Company determined that this transfer was a change in investment strategy. The unrealized holding gains or losses for the available-for-sale securities are reported in other comprehensive income.

Disclosure of accounting policy for investments in financial assets, including marketable securities (debt and equity securities with readily determinable fair values), investments accounted for under the equity method and cost method, securities borrowed and loaned, and repurchase and resale agreements. For marketable securities, the disclosure may include the entity's accounting treatment for transfers between investment categories and how the fair values for such securities are determined. Also, for all investments, an entity may describe its policy for assessing, recognizing and measuring impairment of the investment.
