[1] For investments with active markets, fair value is based on quoted market prices. For non-marketable equity securities, it is not practicable to estimate the fair value because of the lack of the market price and difficulty in estimating fair value without incurring excessive cost. In addition, Kyocera did not identify any events or changes in circumstances that may have had a significant adverse effect on these investments. The aggregated carrying amounts of these investments included in the above table at March 31, 2015 and 2016 were ¥13,651 million and ¥13,514 million, respectively. Fair value of held-to-maturity investments in debt securities is mainly classified as Level 2.

[2] Fair value is estimated by discounting cash flows, using current interest rates for instruments with similar terms and remaining maturities, and classified as Level 2.
