Investments [Abstract]

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]

INVESTMENTS

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. The following table discloses the major categories of the Company's investments as of the periods presented:

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.
