4. INVESTMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair value is the price 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. In determining fair value, the Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or developed by the Company. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:

Level 1 - Valued based on quoted prices at the measurement date for identical assets or liabilities trading in active markets. Financial instruments in this category generally include actively traded equity securities.

Level 2 - Valued based on (a) quoted prices for similar assets or liabilities in active markets; (b) quoted prices for identical or similar assets or liabilities in markets that are not active; (c) inputs other than quoted prices that are observable for the asset or liability; or (d) from market corroborated inputs. Financial instruments in this category include certain corporate equities that are not actively traded or are otherwise restricted.

Level 3 - Valued based on valuation techniques in which one or more significant inputs is not readily observable. Included in this category are certain corporate debt instruments, certain private equity investments, and certain commitments and guarantees.
