NOTE

— FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value measurement guidance clarifies that fair value is an exit price, representing the amount that would be received upon selling an asset or paid upon transferring a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level

measurements) and the lowest priority to unobservable inputs (Level

measurements). The

three

levels of the fair value hierarchy under the fair value measurement guidance are described below

Level

— Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities;

Level

— Quoted prices in markets that are

not

active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

Level

— Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or

market activity).

The following table sets forth certain fair value information at

June 30, 2017

and

December 31, 2016

for financial assets and liabilities measured at fair value by level within the fair value hierarchy, as well as cost or amortized cost. As required by the fair value measurement guidance, assets and liabilities are classified in their entirety based on the lowest level of inputs that is significant to the fair value measurement.

The fair value of the OFC Senior Secured Notes is determined using observable market prices as these securities are traded. The fair value of all the other long-term debt is determined by a valuation model, which is based on a conventional discounted cash flow methodology and utilizes assumptions of current borrowing rates

The fair value of revolving lines of credit is determined using a comparison of market-based price sources that are reflective of similar credit ratings to those of the Company.

The carrying value of other financial instruments, such as revolving lines of credit, deposits, and other long-term debt approximates fair value.
