Fair Value Measurements
Fair value is defined as the price that would be received for an asset or the price that would be paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The accounting standard provides a framework for measuring fair value using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs that may be used to measure fair value are as follows:
Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets 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 assets or liabilities; and
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Our financial instruments consist primarily of cash and cash equivalents and interest rate cap derivatives designated as cash flow hedging instruments. Assets and liabilities measured at fair value on a recurring basis were as follows (in thousands):

(1) Included as cash and cash equivalents.
(2) Interest rate cap hedge premium included as other current assets and other assets.
The fair value of the interest rate cap hedge agreements is determined using pricing models that use observable market inputs as of the balance sheet date, a Level 2 measurement.

There were no transfers between Level 1, Level 2, or Level 3 financial instruments in either 2016 or 2015.
