#### Note 15. Fair Value Measurements
The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

• Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.

• Level 2: Inputs other than quoted prices in active markets in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for similar assets or liabilities that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

• Level 3: Unobservable inputs for which little or no market data exists, therefore requiring management judgment to develop the Company’s own models with estimates and assumptions.

Cash Equivalents – Cash equivalents include investments in government obligation-based money market funds, other money market instruments and interest-bearing deposits with initial or remaining terms of three months or less. The fair value of cash equivalents approximates its carrying value due to the short-term nature of these instruments.

Marketable Securities – Marketable securities utilizing Level 1 and Level 2 inputs include U.S. Treasury Securities, U.S. Government Sponsored Enterprises, floating rate securities, money market mutual funds, corporate debt instruments and other notes, bonds or debt securities issued by non-U.S. sovereign or multilateral entities, as these securities all have quoted prices in active markets.
