Fair value measurements
NOTE 2 – FAIR VALUE MEASUREMENTS

The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company uses the income and market approaches to determine the fair value of its assets and liabilities. The three levels of the fair value hierarchy are set forth below:
Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
Level 2 – Inputs other than quoted prices in active markets included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3 – Unobservable inputs for the asset or liability.

Financial assets and liabilities measured at fair value on a recurring basis:
The carrying amount of the Company’s marketable securities is included in “Other assets, net” on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2016, and December 31, 2015. The Company recorded an increase in fair value related to its marketable securities in the amounts of $0.1 million and $0.4 million for the three months ended March 31, 2016 and 2015, respectively, which were included in “Other income (expense)” on the accompanying Condensed Consolidated Statements of Income.

The tables below identify the estimated fair value of the Company’s marketable securities, determined by reference to quoted market prices (Level 1), as of March 31, 2016, and December 31, 2015 (in thousands):

Non-financial assets and liabilities measured at fair value on a nonrecurring basis:
Certain long-lived non-financial assets and liabilities may be required to be measured at fair value on a nonrecurring basis in certain circumstances, including when there is evidence of impairment. These non-financial assets and liabilities may include assets acquired in a business combination or property and equipment that are determined to be impaired. As of March 31, 2016, and December 31, 2015, the Company did not have any non-financial assets or liabilities that had been measured at fair value subsequent to initial recognition.

Fair value of financial instruments:
The carrying amounts of the Company’s senior notes are included in “Long-term debt” on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2016, and December 31, 2015. See Note 3 for further discussion on the Company’s senior notes.

The table below identifies the estimated fair value of the Company’s senior notes, using the market approach. The fair values as of March 31, 2016, and December 31, 2015, were determined by reference to quoted market prices of the same or similar instruments (Level 2) (in thousands):

The accompanying Condensed Consolidated Balance Sheets include other financial instruments, including cash and cash equivalents, accounts receivable, amounts receivable from suppliers and accounts payable. Due to the short-term nature of these financial instruments, the Company believes that the carrying values of these instruments approximate their fair values.
