Fair Value Measures [Abstract]
Fair Value Measures	Note 4 - Fair Value Measures The Company is required to categorize both financial and nonfinancial assets and liabilities based on the following fair value hierarchy. The fair value of an asset is the price at which the asset could be sold in an orderly transaction between unrelated, knowledgeable, and willing parties able to engage in the transaction. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor in a transaction between such parties, not the amount that would be paid to settle the liability with the creditor. ● Level 1 - Quoted prices in active markets for identical assets or liabilities ● Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, including: o Quoted prices for similar assets or liabilities in active markets o Quoted prices for identical or similar assets in non-active markets o Inputs other than quoted prices that are observable for the asset or liability o Inputs derived principally from or corroborated by other observable market data ● Level 3 - Unobservable inputs for the asset or liability supported by little or no market activity and are significant to the fair value of the assets or liabilities The disclosure of fair value of certain financial assets and liabilities recorded at cost are as follows: Cash and cash equivalents, accounts receivable, and accounts payable: The carrying amount approximates fair value due to the short maturity of these instruments.
