Based on the Company’s ability and intent to hold the investments for a reasonable period of time sufficient for a forecasted recovery of fair value, the Company does not consider any investments to be other-than-temporarily impaired at September 28, 2013. As of September 28, 2013, the Company’s investments in marketable equity securities consist of investments in common stock of industrial and other companies ($2.8 million of the total fair value and $13,000 of the total unrealized losses) and bank trust, insurance, and public utility companies ($1.4 million of the total fair value and $14,000 of the total unrealized losses). As of March 30, 2013, the Company’s investments in marketable equity securities consisted of investments in common stock of industrial and other companies ($3.7 million of the total fair value and $51,000 of the total unrealized losses) and bank trust, insurance, and public utility companies ($1.6 million of the total fair value and $17,000 of the total unrealized losses). The amortized cost and fair value of the Company’s investments in debt securities, by contractual maturity, are shown in the table below (in thousands). Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
