Both the Company's cash equivalents and short-term investments are classified within Level 2 of the fair value hierarchy because they are held to maturity and are valued using interest rates observable at commonly quoted intervals. Cash equivalents are market securities with remaining maturities of three months or less at the date of purchase. The short-term investments are market securities with remaining maturities of over three months at the date of purchase.
The Company's available-for-sale securities are recorded at fair value using quoted market prices or broker-dealer quotations. The Company's available-for-sale securities that are valued using quoted market prices are classified as Level 1 of the fair value hierarchy. The Company's available-for-sale securities classified as Level 2 of the fair value hierarchy consist of equity warrants, which are recorded at fair value based on broker-dealer quotations.
In the event that a decline in the fair value of an investment occurs and the decline in value is considered to be other-than-temporary, an impairment charge is recorded in the interim consolidated statements of income and a new cost basis for the investment is established. The Company assesses whether a decline in value is considered to be other-than-temporary by considering available evidence, including changes in general market conditions, specific industry and individual company data, the length of time and the extent to which the fair value has been less than cost, the financial condition and the near-term prospects of the individual investment. New evidence could become available in future periods which would affect this assessment and thus could result in material impairment charges with respect to those investments for which the cost basis exceeds its fair value.
