|  | · | Level 1:  Investments whose values are based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access.  We use Level 1 inputs for publicly traded unrestricted securities.  Such investments are valued at the closing price for listed securities and at the lower of the closing bid price or the closing sale price for NASDAQ securities on the valuation date. |
|--|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|  | · | Level 2: Investments whose values are based on observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.  These inputs may include quoted prices for the identical instrument in non-active markets, quoted prices for similar instruments in active markets and similar data.  We did not value any of our investments using Level 2 inputs as of June 30, 2013. |

|  | · | Level 3: Investments whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement.  These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the investment.  We used Level 3 inputs for measuring the fair value of approximately 71.0% of our investments as of June 30, 2013. |
