Fair Value Measurements
 
The fair value of a financial instrument is the amount that could be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets are marked to bid prices and financial liabilities are marked to offer prices. Fair value measurements do not include transaction costs. A fair value hierarchy is used to prioritize the quality and reliability of the information used to determine fair values of each financial instrument. Categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is defined into the following three categories:
 
Level 1: Quoted market prices in active markets for identical assets or liabilities.
 
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
 
Level 3: Unobservable inputs that are not corroborated by market data.
 
The following table presents the Company’s hierarchy for its assets, measured at fair value on a recurring basis, as of June 30, 2017 (dollar amounts in thousands):

Investments available-for-sale — The majority of the Company’s investment portfolio consists of U.S. government security funds. The Level 1 securities are valued using quoted prices for identical assets in active markets including equity securities and U.S. government treasuries. 
 
Trading Investment securities — The Company’s trading portfolio consists of various marketable securities that are valued using quoted prices in active markets.
 
For the six months ended June 30, 2017, and for the year ended December 31, 2016, there were no fair value measurements using significant other observable inputs (Level 2) or significant unobservable inputs (Level 3).
 
The carrying amounts reflected on the condensed consolidated balance sheet for cash and cash equivalents, accounts receivable, accounts payable and the revolving credit facility payable approximate fair value due to their short-term nature. During the six months ended June 30, 2017 and 2016, the Company did not have any re-measurements of non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition.
