The amortized cost of our held-to-maturity investments approximates their fair value. As of June 30, 2013 and March 31, 2013, we did not have other-than-temporary impairment in the fair value of any individual security classified as held-to-maturity or available-for-sale. As of June 30, 2013 and March 31, 2013, we had unrealized gains on available-for-sale investments, net of related income taxes of $29,000 and $42,000, respectively. Redemptions of investments in accordance with callable provisions during the three months ended June 30, 2013 and 2012 were $623,000 and $717,000, respectively.
