Investments, Debt and Equity Securities [Abstract] |
Investments | Investments Investments consist of mutual funds and municipal bonds at March 31, 2014 and December 31, 2013. The Company classifies all investments as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies. These investments are carried at fair value, with the unrealized gains and losses reported as a component of accumulated other comprehensive loss until realized. A decline in the market value of any investment below cost that is determined to be other-than-temporary will result in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the investment is established. No such impairment charges were recorded during the three months ended March 31, 2014 or 2013. The following is a summary of short-term investments as of March 31, 2014 and December 31, 2013:
