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:
