Fair Value Measurements and Disclosures
6.  Fair Value Measurements and Disclosures
Financial instruments are carried at fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Assets and liabilities carried at fair value are classified and disclosed in the following three levels: Level 1 - unadjusted quoted market prices in active markets for identical assets and liabilities; Level 2 - inputs other than unadjusted quoted market prices that are observable for the asset or liability, either directly or indirectly (including unadjusted quoted market prices for similar investments, interest rates, credit risk); and Level 3 - unobservable inputs for the asset or liability (including the Partnership's own assumptions used in determining the fair value of investments).

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy.  In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  The Partnership's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.

The Partnership's assets and liabilities measured at fair value on a recurring basis are summarized in the following tables by the type of inputs applicable to the fair value measurements.
