Fair Value Measurements Policy [Abstract]

Fair Value Measurement, Policy [Policy Text Block]

We measure certain assets and liabilities at fair value on a recurring or nonrecurring basis. We categorize each of our fair value measurements into one of three levels as follows:

• Level 1: Quoted prices in active markets for identical assets;

• Level 2: Quoted prices in active markets for similar assets, which we use to value our certificates of deposit, or comparable sales, such as quoted market rates for similar contracts. Specifically, we obtain current pricing from the issuing bank for identical items purchased on the last business day of our reporting period; or

• Level 3: Unobservable inputs that are not corroborated by market data.
