NOTE 4 — MARKETABLE SECURITIES
The amortized cost and fair value of marketable securities as of the dates indicated below were as follows:
(1) Time deposits excluded from fair value measurements.
KLA-Tencor’s investment portfolio consists of both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. All unrealized losses are due to changes in market interest rates, bond yields and/or credit ratings. The Company believes that it has the ability to realize the full value of all of these investments upon maturity. The following table summarizes the fair value and gross unrealized losses of the Company’s investments that were in an unrealized loss position as of the date indicated below:
The contractual maturities of securities classified as available-for-sale, regardless of their classification on the Company’s Consolidated Balance Sheet, as of the date indicated below were as follows:
Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Realized gains on available for sale securities for the fiscal years ended June 30, 2017, 2016 and 2015 were $0.4 million, $0.9 million and $2.4 million, respectively. Realized losses on available for sale securities were immaterial for all years presented.
The entire disclosure for investments in certain debt and equity securities.
