Fair Value Measurements Abstract  
Fair value of financial instruments, policy

The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments.  The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).  The Company uses the income and market approaches to determine the fair value of its assets and liabilities.
