		2	BASIS OF PRESENTATION
	The accompanying unaudited condensed consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The Company believes that the disclosures made are adequate to make the information presented not misleading. All the adjustments which, in the opinion of management, are considered necessary for a fair presentation of the results of operations for the periods shown are of a normal recurring nature and have been reflected in the unaudited condensed consolidated financial statements. Results from operations for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2013. The consolidated balance sheet at December 31, 2012 has been derived from the audited consolidated financial statements at that date. The information included in these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto in our Annual Report on Form 10-K for the year ended December 31, 2012.
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. While the Company believes that such estimates are fair when considered in conjunction with the condensed consolidated financial position and results of operations taken as a whole, the actual amount of such estimates, when known, may vary from these estimates.

DESCRIPTION OF BUSINESS	'
		3	DESCRIPTION OF BUSINESS
	These consolidated financial statements and footnotes include the financial position and operations of Cyalume Technologies Holdings, Inc. (“Cyalume” or the “Company”), a holding company that is the sole shareholder of Cyalume Technologies, Inc. (“CTI”) and of Cyalume Specialty Products, Inc. (“CSP”). CTI is the sole shareholder of Cyalume Technologies, SAS (“CTSAS”), Cyalume Realty, Inc. (“CRI”) and Combat Training Solutions, Inc. (“CTS”). All significant intercompany accounts and transactions have been eliminated in consolidation.
	Our primary focus is providing tactical and training solutions to the military of the U.S. and other countries through both products and services.
	CTI and CTSAS manufacture and sell chemiluminescent products and reflective and photoluminescent materials to military, ammunition, commercial and public safety markets. CTSAS is located in France and represents us in certain international markets, primarily Europe and the Middle East. CTI sells to customers in all other geographic markets. CTI’s and CTSAS’ business operations constitute the majority, based on revenues and assets, of our consolidated business operations.
	CSP manufactures and sells specialty chemical products to the defense, pharmaceutical, cosmetic and other markets. CSP’s operations are located in Bound Brook, New Jersey.
	CRI owns land located in Colorado Springs, Colorado.
	CTS provides its customers with battlefield effects simulation products while its services include planning and implementing tactical training exercises simulating real-world experiences. These products allow military and law enforcement professionals to maintain operational readiness through safe, live training and hands-on situational exercises.
	Our business is managed and financial results are reported as one segment. Our CEO, who is our chief operating decision maker, focuses on consolidated results to make strategic and tactical decisions. Our one operating segment consists of four reporting units: Chemical Light (the operations of CTI and CTSAS), Training (the operations of CTS), Specialty Products (the operations of CSP) and Other (the operations of CRI and the parent company Cyalume Technologies Holdings, Inc.).
	For the three and nine months ended September 30, 2013, the Company had a net loss of approximately $7.8 million and $9.7 million, respectively, and for the nine months ended September 30, 2013, the Company used approximately $2.3 million of cash in its operating activities. As of September 30, 2013, the Company has an accumulated deficit of approximately $89.9 million and the Company’s unrestricted cash balance was approximately $1.6 million.
	In light of the Company’s secured notes payable maturing on December 19, 2013 and March 19, 2014, and the Company’s line of credit maturing on December 19, 2013 (see Note 8), management has been evaluating various possibilities, including but not limited to refinancing or restructuring the Company’s debt and raising additional capital through the issuance of common stock, preferred stock, or securities convertible into common stock. These possibilities, to the extent available, may be on terms that result in significant dilution to the Company’s existing stockholders, may reduce the value of stockholders’ investment in the Company or may impact the Company’s stock price. There can be no assurances that the Company will be successful in refinancing or restructuring its debt or raising additional capital. The Company’s condensed consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of assets and liabilities that might be necessary should the Company be unable to refinance or restructure its debt, or otherwise meet its payment obligations under its existing arrangements.

	4.	IMPAIRMENT CHARGES
	During the second quarter of 2013, CTS recorded a goodwill impairment loss of $168,000 and a loss on impairment of certain amortizing intangible assets of $875,000. See Note 6 for activity affecting our goodwill asset during the nine months ending September 30, 2013. See Note 13 for fair value information on these assets.
	During the second quarter of 2013, management conducted an annual review of tangible and intangible assets for impairment. Before assessing whether any of our reporting units’ goodwill was impaired, we first assessed whether any non-goodwill assets were impaired. This assessment determined that the CTS patent asset was impaired by approximately $174,000, CTS trademarks and trade names were impaired by approximately $17,000, CTS customer relationships intangibles were impaired by approximately $650,000 and CTS non-compete agreements were impaired by approximately $34,000. Therefore, the Company recorded $875,000 of an impairment loss on these CTS intangible assets during the second quarter of 2013.
	The “step 1” goodwill impairment assessment was performed by comparing the fair value of each reporting unit containing goodwill to those reporting units’ carrying values. Our Chemical Light, Training, and Specialty Products reporting units have goodwill assets. Since there are no quoted market prices for our reporting units, the fair value of our reporting units were determined using a discounted present value technique utilizing each reporting unit’s forecasted after-tax cash flows. The “step 1” test determined that the carrying value of the CTS Training reporting unit exceeded its fair value, and therefore its goodwill needed to be tested further under what is commonly known as “step 2” of the goodwill impairment assessment. CTS did not pass the “step 1” test due to the inability to both gain traction with new products and services and attract new customers as initially planned when the reporting unit was acquired in December 2011.
	Under “step 2” of the goodwill impairment assessment, we compared the implied fair value of CTS Training’s goodwill with the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value of that goodwill, that excess must be recognized as an impairment loss. The implied fair value of goodwill was determined in the same manner as the amount of goodwill recognized in a business combination. The excess of the fair value of the reporting unit over the amounts assigned to its assets and liabilities is the implied amount of the reporting unit’s goodwill. We identified several intangible assets that were valued during this process, including customer relationships, patents, trade names, non-compete agreements, and our workforce. The allocation process was performed only for purposes of goodwill impairment. We determined the fair value of these assets using various discounted cash flow-based methods that utilize assumptions such as the ability of these assets to generate future cash flows, present-value factors, income tax rates and customer attrition rates. The “step 1” calculated fair value of the CTS reporting unit was allocated to the CTS tangible and identifiable intangible assets of the CTS reporting unit at June 30, 2013 based upon the results of the “step 2” analysis, which was a full impairment to the CTS goodwill.

	Interest rate swaps		Derivatives liability (current liabilities)			-155
	Currency Forward Contracts
	CTSAS’s functional currency is the Euro. Periodically, CTSAS purchases inventory from CTI, which requires payment in U.S. dollars. Beginning in 2009, and only under certain circumstances, we use currency forward contracts to mitigate CTSAS’s exposure to changes in the Euro-to-U.S. dollar exchange rate upon payment of these inventory purchases. Such currency forward contracts typically have durations of less than six months. We report these currency forward contracts at their fair value. This relationship has not been designated as a hedge and therefore all changes in these currency forward contracts’ fair value are recorded in other expenses (income), net on our condensed consolidated statement of comprehensive loss. At September 30, 2013, we held no such currency forward contracts. See Note 13 for a description of how we estimate the fair value of these contracts.
	Interest Rate Swaps
	In December 2008, we entered into two pay-fixed, receive-variable, interest rate swaps to reduce exposure to changes in cash payments caused by changes in interest rates on our notes payable with TD Bank, N.A. (“TD Bank”) Both relationships are designated as cash flow hedges and meet the criteria for the shortcut method for assessing hedge effectiveness; therefore, the hedge is assumed to be 100% effective and all changes in the fair value of the interest rate swaps are recorded in comprehensive income (loss). Such changes were due to unrealized gains and losses on the interest rate swaps. These unrealized gains and losses must be reclassified in whole or in part into earnings if, and when, a comparison of the swap(s) and the related hedged cash flows demonstrates that the shortcut method is no longer applicable. We expect these hedges to meet the criteria of the shortcut method for the duration of the hedging relationship, which ends upon maturity of the notes payable with TD Bank, and therefore, we do not expect to reclassify any portion of these unrealized losses from accumulated other comprehensive loss to earnings in the future. See Note 13 for a description of how we estimate the fair value of these swaps.

DEBT	'
	8	DEBT
	Line of Credit
	CTI has a line of credit with a maximum borrowing capacity of $5.0 million with TD Bank, used to support working capital needs. The amount we may borrow from this line of credit is dependent mainly on accounts receivable and inventory balances. The line of credit expires on December 19, 2013. At September 30, 2013, there were $3.6 million of outstanding borrowings on this line of credit. At December 31, 2012, there were no outstanding borrowings on this line of credit.
	Senior Debt
	CTI has two loans payable to TD Bank: a Term Loan and a Real Estate Loan, that were originally entered into on December 19, 2008, and which were amended twice during 2012 to modify certain financial and non-financial covenants required by these loans.
	The Term Loan is payable in monthly principal installments of $148,000 along with monthly interest payments, plus a one-time principal payment of $6.7 million due at maturity on December 19, 2013. The Real Estate Loan is payable in monthly principal installments of $10,000, along with monthly interest payments, plus a one-time principal payment of $1.7 million due at maturity on December 19, 2013.
	Subordinated Term Loan
	On July 29, 2010 we issued a Subordinated Term Loan of $8.5 million to Granite Creek Partners Agent, LLC (“Granite Creek”) that matures March 19, 2014. Interest is payable monthly beginning September 1, 2010 at a rate of 11% per annum. No principal payments are required until maturity. We have the right to prepay the loan in whole or in part at any time without penalty.

	The effective tax rates for the three months ended September 30, 2013 and September 30, 2012 were approximately 20% and 2%, respectively, compared to the federal statutory rate of 34%. The effective tax rates for the nine months ended September 30, 2013 and September 30, 2012 were approximately 24% and 3%, respectively, compared to the federal statutory rate of 34%. The Company increased its valuation allowance during the three and nine months ended September 30, 2013 by approximately $1.8 million due to management’s assessment that it is more likely than not that a portion of certain deferred tax assets may not be realized. The Company has a valuation allowance of approximately $5.7 million as of September 30, 2013 against deferred tax assets generated primarily as a result of foreign tax credits. The 2012 effective rate differed from the statutory rate primarily due to the 2012 goodwill impairment.

	CSP leases industrial-use property in Bound Brook, New Jersey, U.S.A. from Brook Industrial Park, LLC, an entity that is controlled by an employee of CSP who is also an owner of a significant amount of our common shares and is one of our board members. The lease ends on August 31, 2016, with extension options available, and requires lease payments of $24,000 per month from September 1, 2011 through August 31, 2013; thereafter, the monthly lease payments were adjusted to reflect the changes of average cost per square foot as reported by Newmark Knight and Frank in their 2nd Quarter 2013 New Jersey Industrial Market Report, Average Asking Rate for Somerset County to approximately $30,000 per month beginning September 1, 2013.
	This same related party controls JFC Technologies, LLC (“JFC”). In December 2012, we entered into a $2.1 million unsecured promissory note with JFC. The note accrues interest initially at the rate of 5% per annum. If payments have not begun on the unsecured promissory note by December 31, 2013, the interest rate increases by 1% per month beginning on January 1, 2014, up to a maximum rate of 11% (the increased rate is retroactive to the initial issuance date for a total maximum interest expense amount of $346,500 through the maturity date). The unsecured promissory note is payable in full on the earlier of June 30, 2014 or upon the refinancing of our existing indebtedness (subject to the availability of at least $5.0 million in available credit after such repayment). Interest expense at the maximum rate of 11% retroactive to the initial issuance date on this note totaled approximately $173,000 in the nine months ended September 30, 2013. No principal or interest payments have been made on this note.
	Management Agreement with our Board Member

	Contingent Consideration Liability for the Acquisition of Combat Training Solutions, Inc.
	On December 22, 2011, CTI entered into a Stock Purchase Agreement (“SPA”) with CTS and the sole stockholder of CTS. Pursuant to the SPA, CTI purchased all of the issued and outstanding capital stock of CTS using a combination of cash, shares of our common stock plus other consideration that is contingent on future financial performance of CTS. The contingent consideration ranges from $0 to $5.75 million and is based on the financial performance of the acquired business during the combined calendar years 2012 and 2013, to be paid after calendar year 2013 when CTS’s financial performance is known. Up to $5.5 million of the contingent payment is based on CTS achieving certain cumulative gross margin thresholds during the calendar years ending December 31, 2012 and 2013. This payment will consist of a combination of cash and our common stock. An additional payment of $250,000 of our common stock is contingent upon CTS achieving cumulative gross margin of $6.0 million during calendar years ending December 31, 2012 and 2013.
	See Note 13 for an estimate of the fair value of this liability and a description of how we estimate its fair value.
	Legal
	Civil Action No. 06-706 in Superior Court of the Commonwealth of Massachusetts
	On January 23, 2006, before we owned CTI, the former owners of CTI (from whom we purchased CTI) (the “Former Owners”) acquired all of the outstanding capital stock of Omniglow Corporation (the “Transaction”) and changed the name of the company to Cyalume Technologies, Inc. Prior to, or substantially simultaneously with, the Transaction, CTI sold certain assets and liabilities related to Omniglow Corporation’s novelty and retail business to certain former Omniglow Corporation stockholders and management (the “Omniglow Buyers”). This was done because CTI sought to retain only the Omniglow Corporation assets and current liabilities associated with its government, military and safety business. During 2006, CTI and the Omniglow Buyers commenced litigation and arbitration proceedings against one another. Claims include breaches of a lease and breaches of various other agreements between CTI and the Omniglow Buyers. These proceedings are known as Civil Action No. 06-706 in Superior Court of the Commonwealth of Massachusetts (the “Court”).
	On December 19, 2008, while Civil Action 06-706 was still unresolved, we acquired CTI (the “Acquisition”). According to the Stock Purchase Agreement between the Former Owners and us, the Former Owners retained the responsibility for paying for all costs and liabilities associated with Civil Action No. 06-706.
	On July 18, 2011, CTI received an Order for Entry of Final Judgment in Civil Action No. 06-706 in which the Court awarded approximately $2.6 million in damages to Omniglow, LLC. Prejudgment interest at the rate of 12% percent per annum since the filing of the complaint in 2006 will accrue on approximately $1.3 million of the damages. The Court also awarded Omniglow, LLC reimbursement of attorney fees and costs of approximately $235,000, on which interest at the rate of 12% percent per annum will accrue beginning with the date of the final ruling.
	On July 12, 2012, the Court issued an Amended Final Judgment and, on September 20, 2012, a Final Judgment. There were no changes to the previously described damage awards. In response, on October 17, 2012, we filed our Notice of Appeal and on August 2, 2013, we filed our Formal Appeal. Our appeal contains a number of bases for overturning the awards.
	Although we have appealed the final judgment, we previously recorded a contingent legal obligation in the full amount of the final ruling (approximately $3.9 million). Since the Former Owners (i) retained the responsibility for paying the costs and liabilities associated with Civil Action No. 06-706 and (ii) are related parties under U.S. GAAP due to their ownership interest in us and their membership on our board of directors, the Company recorded approximately $4.3 million, which includes the $3.9 million contingent legal obligation and other costs incurred while litigating Civil Action No. 06-706, within due from related party, net on the condensed consolidated balance sheet as of September 30, 2013. This due from related party, net amount is offset by an allowance of approximately $3.7 million as of September 30, 2013, which is recorded on the provision for uncollectible receivable – related party line item on the Company’s condensed consolidated statements of comprehensive loss. The overall due from related party, net amount is approximately $563,000 as of September 30, 2013. In connection with certain financial transactions being negotiated by the Company, management expects a modification to an indemnification agreement limiting the collectible amount of this related party receivable to approximately $563,000.
	Arbitration with Former Employee
	On December 22, 2011, CTI entered into the SPA with CTS and Antonio Colon, the sole stockholder of CTS. Pursuant to the SPA, CTI purchased all of the issued and outstanding capital stock of CTS in return for consideration that included contingent consideration ranging from $0 to $5.75 million, which is based on CTS’s financial performance during the period of January 1, 2012 through December 31, 2013.
	On June 15, 2012, we received a copy of a demand for arbitration filed by Mr. Colon with the American Arbitration Association. The demand alleges, among other things, that CTI had constructively terminated Mr. Colon’s employment without cause and that Cyalume and CTI had breached certain provisions of the SPA. Mr. Colon seeks, among other things, payment of the maximum potential contingent consideration amount of $5.75 million, payment of salary, wages, bonuses and benefits pursuant to Mr. Colon’s employment agreement with CTI, and reimbursement of his attorneys’ fees and costs related to this matter.
	Cyalume and CTI considered the allegations in the Demand for Arbitration by Mr. Colon to be without merit and, in addition, the position of Cyalume and CTI was that Mr. Colon was not constructively terminated. On August 17, 2012, Mr. Colon filed a Complaint in Federal Court and on September 11, 2012, he filed to have the arbitration withdrawn. In addition, on September 11, 2012, Mr. Colon chose to cease working for us.
	CTI filed a Motion to Dismiss the Complaint in Federal Court and to compel the controversy to arbitration before the American Arbitration Association. The District Court for the District of Delaware held a hearing on January 23, 2013, at which it dismissed the Complaint in Federal Court without prejudice and indicated that the arbitration should proceed. On September 23, 2013, the parties entered into an agreement to resolve this matter, the terms of which call for the Company to make a series of payments over five years to Mr. Colon and to transfer a property located in Colorado Springs, CO to Mr. Colon. The property was originally acquired by the Company at the time of the CTS acquisition on December 22, 2011.

FAIR VALUE

Under U.S. GAAP, we are required to record certain financial assets and liabilities at fair value and may choose to record other financial assets and financial liabilities at fair value as well. Also under U.S. GAAP, we are required to record nonfinancial assets and liabilities at fair value due to events that may or may not recur in the future, such as an impairment event. When we are required to record such assets and liabilities at fair value, that fair value is estimated using an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. That fair value is determined based on significant inputs contained in a fair value hierarchy as follows:

Level 1

Quoted prices for identical assets or liabilities in active markets to which we have access at the measurement date.

Level 2

Inputs other than quoted prices 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.

The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

There are three general valuation techniques that may be used to measure fair value, as described below:

Market Approach

Uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Prices may be indicated by pricing guides, sale transactions, market trades, or other sources.

Cost Approach

Based on the amount that currently would be required to replace the service capacity of an asset (replacement cost).

Income Approach

Uses valuation techniques to convert future amounts to a single present amount based on current market expectations about the future amounts (includes present value techniques and option-pricing models).

Net present value is an income approach where a stream of expected cash flows is discounted at an appropriate market interest rate.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The fair values of the swaps are determined by discounting the estimated cash flows to be received and paid due to the swaps over the swap’s contractual lives using an estimated risk-free interest rate for each swap settlement date (an income approach).

We did not transfer any assets or liabilities between Levels 1, 2 or 3 during the nine months ended September 30, 2013. Any such transfer would be based on a review of the inputs used that are significant to the fair value measurement of that asset or liability.

We have other financial instruments, such as cash, accounts receivable, due from related party, accounts payable, notes payable and line of credit. We believe the carrying amounts of those assets and liabilities approximate their fair value since we have estimated those carrying amounts to approximate the exit price we would receive to sell these assets or pay to transfer these liabilities to a market participant.

Our contingent consideration liability resulting from our acquisition of CTS is our only asset or liability that is measured at fair value on a recurring basis using significant unobservable inputs (Level 3). The fair value of that liability was $0 as of September 30, 2013 and December 31, 2012 and there were no increases or decreases in its fair value during the nine months ended September 30, 2013. The only significant unobservable inputs used in the fair value measurement of this liability is the estimated gross margin (revenues less cost of revenues) for the cumulative calendar years 2012 and 2013, which was estimated to be $3.0 million as of December 31, 2012 and $2.0 million as of September 30, 2013. The maximum payout under this arrangement occurs when the estimated gross margin is $8.5 million; at such an amount, the fair value of this liability would be $5.0 million as of September 30, 2013. Because the estimated cumulative gross margin was well below $6.0 million as of September 30, 2013, the fair value of this liability was $0 as of September 30, 2013.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

During the second quarter of 2013, the following assets, all of which are Level 3 assets, were identified as impaired and were adjusted to their fair values (in thousands of dollars) (see also Notes 4 and 6):

We are managed as one operating segment with four reporting units: Chemical Light (the operations of CTI and CTSAS), Training (the operations of CTS), Specialty Products (the operations of CSP) and Other (the operations of CRI and the parent company Cyalume Technologies Holdings, Inc.). Both Chemical Lights’ goodwill and Specialty Products’ goodwill was not considered to be impaired and our Other reporting unit does not have a goodwill asset.

-2

The fair value of the impaired goodwill asset was determined calculating the excess of the fair value of the reporting unit over the fair values assigned to its assets and liabilities and utilized present value techniques utilizing each reporting unit’s forecasted after-tax cash flows.

-3

The fair value of the impaired patent asset was determined using the “relief from royalty” method, which calculates the present value of a stream of estimated future royalty payments that an entity would be willing to pay in order to utilize the patents, net of estimated income taxes (an income approach).

-4

The fair value of the impaired trademarks and trade names asset was determined using the “relief from royalty” method, which calculates the present value of a stream of estimated future royalty payments that an entity would be willing to pay in order to utilize the trademarks and trade names, net of estimated income taxes (an income approach).

-5

The fair value of the impaired non-compete agreement asset was determined using the “comparative business valuation” method, which compares the present value of two streams of the reporting unit’s estimated future cash flows; one stream assuming the non-compete agreements are in place and the other stream assuming the agreements are not in place (an income approach).

-6

The fair value of the customer relationships was determined using a multi-period excess earning method (an income approach), with key inputs being estimated customer attrition rates, revenue growth rates and a risk-adjusted discount rate.

Assets and Liabilities Measured at Fair Value on Non-Recurring Basis	'
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	During the second quarter of 2013, the following assets, all of which are Level 3 assets, were identified as impaired and were adjusted to their fair values (in thousands of dollars) (see also Notes 4 and 6):
			Cyalume Reporting Unit (1)		Loss Recognized			Fair Value
	Goodwill (2)		Training		$	168		$	0
	Patents (3)		Training			174			17
	Trademarks and trade name (4)		Training			17			0
	Non-compete agreements (5)		Training			34			0
	Customer Relationships (6)		Training			650			60
		-1	We are managed as one operating segment with four reporting units: Chemical Light (the operations of CTI and CTSAS), Training (the operations of CTS), Specialty Products (the operations of CSP) and Other (the operations of CRI and the parent company Cyalume Technologies Holdings, Inc.). Both Chemical Lights’ goodwill and Specialty Products’ goodwill was not considered to be impaired and our Other reporting unit does not have a goodwill asset.
		-2	The fair value of the impaired goodwill asset was determined calculating the excess of the fair value of the reporting unit over the fair values assigned to its assets and liabilities and utilized present value techniques utilizing each reporting unit’s forecasted after-tax cash flows.
		-3	The fair value of the impaired patent asset was determined using the “relief from royalty” method, which calculates the present value of a stream of estimated future royalty payments that an entity would be willing to pay in order to utilize the patents, net of estimated income taxes (an income approach).
		-4	The fair value of the impaired trademarks and trade names asset was determined using the “relief from royalty” method, which calculates the present value of a stream of estimated future royalty payments that an entity would be willing to pay in order to utilize the trademarks and trade names, net of estimated income taxes (an income approach).
		-5	The fair value of the impaired non-compete agreement asset was determined using the “comparative business valuation” method, which compares the present value of two streams of the reporting unit’s estimated future cash flows; one stream assuming the non-compete agreements are in place and the other stream assuming the agreements are not in place (an income approach).
		-6	The fair value of the customer relationships was determined using a multi-period excess earning method (an income approach), with key inputs being estimated customer attrition rates, revenue growth rates and a risk-adjusted discount rate.

[1]	We are managed as one operating segment with four reporting units: Chemical Light (the operations of CTI and CTSAS), Training (the operations of CTS), Specialty Products (the operations of CSP) and Other (the operations of CRI and the parent company Cyalume Technologies Holdings, Inc.). Both Chemical Lights’ goodwill and Specialty Products’ goodwill was not considered to be impaired and our Other reporting unit does not have a goodwill asset.
[2]	The fair value of the impaired goodwill asset was determined calculating the excess of the fair value of the reporting unit over the fair values assigned to its assets and liabilities and utilized present value techniques utilizing each reporting unit’s forecasted after-tax cash flows.
[3]	The fair value of the impaired patent asset was determined using the “relief from royalty” method, which calculates the present value of a stream of estimated future royalty payments that an entity would be willing to pay in order to utilize the patents, net of estimated income taxes (an income approach).
[4]	The fair value of the impaired trademarks and trade names asset was determined using the “relief from royalty” method, which calculates the present value of a stream of estimated future royalty payments that an entity would be willing to pay in order to utilize the trademarks and trade names, net of estimated income taxes (an income approach).
[5]	The fair value of the impaired non-compete agreement asset was determined using the “comparative business valuation” method, which compares the present value of two streams of the reporting unit’s estimated future cash flows; one stream assuming the non-compete agreements are in place and the other stream assuming the agreements are not in place (an income approach).
[6]	The fair value of the customer relationships was determined using a multi-period excess earning method (an income approach), with key inputs being estimated customer attrition rates, revenue growth rates and a risk-adjusted discount rate.
