Note 2. Fair Value Measurements

We define fair value as the exchange price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:

 

Level 1—Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

 

Level 2—Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.

 

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. These inputs are based on our own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.

We measure restricted cash at fair value on a recurring basis. We classify this asset within Level 1 or Level 2 because they are valued using either quoted market prices for identical assets or inputs other than quoted prices that are directly or indirectly observable in the market, including readily-available pricing sources for the identical underlying security which may not be actively traded. We had restricted cash in the form of certificates of deposits of $26.5 million and $26.8 million as of October 31, 2017 and January 31, 2017, respectively, classified within Level 2.

On November 29, 2017, in connection with our entry into a new secured credit agreement with Wells Fargo Bank, National Association (November 2017 Facility), we utilized an available sublimit for the issuance of $26.0 million in letters of credit and released the restrictions on the corresponding certificates of deposits. Accordingly, we released $26.0 million from restricted cash to cash and cash equivalents. Refer to Note 12 for additional details.
