	Fair Value of Financial Instruments
	The Company had $100.8 million and $28.5 million of cash equivalents at March 31, 2014 and December 31, 2013, respectively, which were primarily investments in money market funds. The Company has categorized its cash equivalents as a Level 1 financial asset, measured at fair value based on quoted prices in active markets of identical assets. The fair value of the Company’s forward currency contracts and interest rate swap contracts as of March 31, 2014 and December 31, 2013 are disclosed in Note 5, "Derivative Financial Instruments," of the Notes to the Consolidated Financial Statements below and are based on Level 2 inputs. The fair value of the Company’s senior unsecured notes as described in Note 13, "Long-Term Debt," of the Notes to the Consolidated Financial Statements is approximately $258.1 million based upon Level 2 inputs at March 31, 2014. The fair value of the Company's term loan, also described in Note 13, approximates the carrying value due to the variable market rate used to calculate interest payments. The Company does not have any other significant financial assets or liabilities that are measured at fair value.
	The carrying amount of accounts receivable, accounts payable and accrued payroll and related liabilities approximates the fair value of those instruments due to their short-term nature.

Goodwill	'
	Goodwill
	In February 2014, the Company announced a realignment of its business which resulted in the elimination of its division structure and the formation of six reporting segments effective as of January 1, 2014. This reorganization requires that the Company reassign its reported goodwill as of January 1, 2014 to its new reporting units based on the relative fair value of the respective business units at that time. The Company is in the process of performing this valuation analysis which is expected to be finalized by June 30, 2014. Subsequent to the reallocation of goodwill, an impairment test of each new reporting unit is required to be performed, and a potential impairment could be deemed to exist as a result of this process. The Company will record any such potential impairment, if identified, during the fiscal quarter ending June 30, 2014.
	The carrying value of goodwill and the activity for the three months ended March 31, 2014 are as follows (in thousands):

	The Company and its subsidiary, Indigo Systems Corporation (now known as FLIR Commercial Systems, Inc.) (together, the “FLIR Parties”), were named in a lawsuit filed by Raytheon Company (“Raytheon”) on March 2, 2007 in the United States District Court for the Eastern District of Texas. Raytheon's complaint, as amended, asserted claims for tortious interference, patent infringement, trade secret misappropriation, unfair competition, breach of contract and fraudulent concealment. The FLIR Parties filed an answer to the complaint on September 2, 2008, in which they denied all material allegations. On August 31, 2009, the court entered an order granting the FLIR Parties' motion for summary judgment on Raytheon's trade secret misappropriation claim based on the FLIR Parties' statute of limitations defense. Raytheon abandoned all of its other claims except its claims relating to four patents (the “Patent Claims”). On August 11, 2010, the FLIR Parties and Raytheon entered into an agreement in principle to resolve the remaining Patent Claims, which resulted in a payment of $3 million by the FLIR Parties to Raytheon and entitles the FLIR Parties to certain license rights in the patents that were the subject of the Patent Claims. The parties appealed certain rulings of the District Court to the United States Court of Appeals for the Federal Circuit, which on August 1, 2012 reversed the judgment of the District Court and remanded the case for further proceedings consistent with the appellate court's opinion.  The Company intends to vigorously defend itself in this matter and is unable to estimate the amount or range of potential loss, if any, which might result if the outcome in this matter is unfavorable.
