The Company regularly reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment.  The Company does not believe that its investments in marketable securities with unrealized losses at July 31, 2015 are other-than-temporary due to market volatility of the security’s fair value, analysts’ expectations and the Company’s ability to hold the securities for a period of time sufficient to allow for any anticipated recoveries in market value.

During the three months ended July 31, 2015 and 2014, the Company sold or redeemed available-for-sale securities in the amounts of $713,000 and $2.2 million, respectively, realizing gains of approximately $137,000 and $280,000, respectively.

Maturities of fixed income securities classified as available-for-sale at July 31, 2015 are as follows, at cost (in thousands):

Current
  $ 101  
Due after one year through five years
    1,622  
Due after five years through ten years

The fair value accounting framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value.  The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements).  The three levels of the fair value hierarchy are described below:

 
Level 1
Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

 
Level 2
Inputs to the valuation methodology include:

 
- Quoted prices for similar assets or liabilities in active markets;

 
- Quoted prices for identical or similar assets or liabilities in inactive markets

 
- Inputs other than quoted prices that are observable for the asset or liability;

 
- Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

 
Level 3
Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.  Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.  All of the Company’s investments in marketable securities are valued on a Level 1 basis.
