Notes to Consolidated Financial Statements (Unaudited)

1. Basis Of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation. Operating results for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. These financial statements should be read in conjunction with the Company’s audited financial statements and notes thereon included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Unless the context requires otherwise, the terms the “Company,” “SL Industries,” “we,” “us” and “our” mean SL Industries, Inc., a Delaware corporation, and its consolidated subsidiaries after Reincorporation (defined and described below) and SL Industries, Inc., a New Jersey corporation prior to Reincorporation. In the context of describing the Reincorporation, “SL-NJ” means SL Industries, Inc., a New Jersey corporation, and “SL-DE” means SL Industries, Inc., a Delaware corporation and wholly owned subsidiary of SL-NJ.

On May 9, 2013, the Company’s shareholders voted to approve a proposal to change the state of incorporation of SL Industries from the State of New Jersey to the State of Delaware by merging SL-NJ with and into SL-DE (the “Reincorporation”). On June 20, 2013 (the “Effective Date”), the Reincorporation was effected by merging SL-NJ with and into SL-DE pursuant to an Agreement and Plan of Merger, dated June 3, 2012, between SL-NJ and SL-DE. SL-DE survived the merger and SL-NJ ceased to exist. The principal reason for the Reincorporation was to give the Company a greater measure of flexibility and simplicity in corporate governance and provide greater clarity and predictability with respect to the Company’s corporate legal affairs. The Reincorporation did not result in any change in the name, business, management, fiscal year, accounting, location of the principal executive officers, assets or liabilities or net worth (other than the costs of reincorporation which were immaterial) of the Company.

4. Income Per Share

The Company has presented net income per common share pursuant to Accounting Standards Codification (“ASC”) 260 “Earnings Per Share.” Basic net income per common share is computed by dividing reported net income available to common shareholders by the weighted average number of shares outstanding for the period.

Diluted net income per common share is computed by dividing reported net income available to common shareholders by the weighted average shares outstanding for the period, adjusted for the dilutive effect of common stock equivalents, which consist of stock options, using the treasury stock method.

7

The table below sets forth the computation of basic and diluted net income per share:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2013			2012			2013			2012
	(in thousands, except per share amounts)
Basic net income available to common shareholders:
Net income available to common shareholders from continuing operations	$	3,434		$	2,865		$	8,670		$	5,719
Diluted net income available to common shareholders from continuing operations	$	3,434		$	2,865		$	8,670		$	5,719
Shares:
Basic weighted average number of common shares outstanding		4,134			4,121			4,144			4,375
Common shares assumed upon exercise of stock options		50			12			46			15
Diluted weighted average number of common shares outstanding		4,184			4,133			4,190			4,390
Basic net income (loss) per common share:
Income from continuing operations	$	0.83		$	0.69		$	2.09		$	1.31
(Loss) from discontinued operations (net of tax)		(0.07	)		(0.11	)		(0.18	)		(0.21	)
Net income	$	0.76		$	0.58		$	1.91		$	1.10
Diluted net income (loss) per common share:
Income from continuing operations	$	0.82		$	0.69		$	2.07		$	1.30
(Loss) from discontinued operations (net of tax)		(0.07	)		(0.11	)		(0.18	)		(0.20	)
Net income	$	0.75		$	0.58		$	1.89		$	1.10

For the three and nine months ended September 30, 2013, no stock options were excluded from the dilutive computation because the option exercise prices were not greater than the average market price of the Company’s common stock.

For the three and nine months ended September 30, 2012, 9,000 and 6,000 stock options were excluded from the dilutive computation, respectively, because the option exercise prices were greater than the average market price of the Company’s common stock.

5. Stock-Based Compensation

At September 30, 2013, total compensation expense (included in selling, general and administrative expense) related to stock-based compensation plans for the three and nine months ended September 30, 2013 was $114,000 and $446,000 ($85,000 and $326,000 net of tax), respectively. For the three and nine months ended September 30, 2012, total compensation expense was $165,000 and $909,000 ($154,000 and $631,000, net of tax), respectively.

8

During the first quarter of 2013, the Company implemented a Long-Term Incentive Plan (the “2013 LTIP”) pursuant to the 2008 Incentive Stock Plan (the “2008 Plan”) which awarded restricted stock units (“RSUs”) to eligible executives. Under the terms of the 2013 LTIP, the number of RSUs that may vest, if any, will be based on, among other things, the Company achieving certain sales and return on invested capital (“ROIC”), as defined, targets during the January 2013 to December 2015 performance period. Earned RSUs, if any, cliff vest at the end of fiscal 2015 (100% of earned RSUs vest at December 31, 2015). The final value of these RSUs will be determined by the number of shares earned. The value of these RSUs is charged to compensation expense on a straight-line basis over the three year vesting period with periodic adjustments to account for changes in anticipated award amounts. The weighted-average price for these RSUs was $19.17 per share based on the grant date of March 5, 2013. During the three and nine months ended September 30, 2013, $31,000 and $74,000 was charged to compensation expense, respectively. As of September 30, 2013, total unamortized compensation expense for this grant was $292,000. As of September 30, 2013, the maximum number of achievable RSUs under the 2013 LTIP was 28,000 RSUs.

On May 9, 2013, the Company granted each Director 3,000 restricted shares pursuant to the 2008 Plan. The shares vest upon the first anniversary of the grant date. Based on the terms of the awards the value of these restricted shares is charged to compensation expense on a straight-line basis over the one year vesting period. As a result, the Company recognized $77,000 and $122,000 of stock compensation expense during the three and nine months ended September 30, 2013, respectively. As of September 30, 2013, total unamortized compensation expense for this grant was $187,000. The weighted-average price of these restricted stock grants was $20.60 per share based on the grant date of May 9, 2013. As of September 30, 2013, no shares were granted under this award.

Stock Options

Option activity under the principal option plans as of September 30, 2013 and changes during the nine months ended September 30, 2013 were as follows:

	Outstanding Options			Weighted Average Exercise Price		Weighted Average Remaining Life		Aggregate Intrinsic Value
	(in thousands)					(in years)		(in thousands)
Outstanding as of December 31, 2012		135		$	12.79		4.33	$	670
Granted		—			—
Exercised		(46	)		13.64
Forfeited		—			—
Expired		—			—
Outstanding as of September 30, 2013		89		$	12.35		3.58	$	1,129
Exercisable as of September 30, 2013		83		$	11.99		3.54	$	1,074

9

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the third quarter of fiscal 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2013. This amount changes based on the fair market value of the Company’s stock. The total intrinsic value of options exercised for the nine months ended September 30, 2013 was $563,000. No options were exercised during the nine months ended September 30, 2012.

As of September 30, 2013, $10,000 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 0.2 years.

Tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options are classified as financing cash flows. Cash received from option exercises for the nine months ended September 30, 2013 was $631,000. The actual tax benefit realized for the tax deduction from option exercises of share-based payment arrangements totaled $203,000 for the nine months ended September 30, 2013. No options were exercised during the nine months ended September 30, 2012. The Company has applied the “Short-cut” method in calculating the historical windfall tax benefits. All tax shortfalls will be applied against this windfall before being charged to earnings.

6. Income Tax

The Company calculates its interim tax provision in accordance with the provisions of ASC 740-270 “Income Taxes – Interim Reporting.” For each interim period the Company estimates its annual effective income tax rate and applies the estimated rate to its year-to-date income or loss before income taxes. The Company also computes the tax provision or benefit related to items separately reported, such as discontinued operations, and recognizes the items net of their related tax effect in the interim periods in which they occur. The Company also recognizes the effect of changes in enacted tax laws or rates in the interim periods in which the changes occur.

For the nine months ended September 30, 2013 and September 30, 2012, the estimated income tax rate from continuing operations was 27% and 31%, respectively. The decrease in the effective tax rate was primarily due to the recording of a research and development tax benefit of $906,000 in 2013, of which $431,000 was related to the retroactive reinstatement of the federal research and development tax credits from the enactment of the American Tax Relief Act of 2012. These credits were not available to the Company in 2012.

During the three months ended September 30, 2013, the Company recorded additional benefits from federal and state research and development tax credits of $245,000 and $67,000 respectively. During the nine months ended September 30, 2013, the Company recorded additional benefits from federal and state research and development tax credits of $741,000 and $165,000 respectively. The Company did not record additional benefits from federal and state research and development tax credits during the three and nine months ended September 30, 2012.

As of September 30, 2013, the Company’s gross research and development tax credit carryforwards totaled approximately $1,120,000. Of these credits, approximately $453,000 can be carried forward for 15 years and will expire between 2015 and 2028, and approximately $667,000 of state credits can be carried forward indefinitely.

10

The Company has recorded gross unrecognized tax benefits, excluding interest and penalties, as of September 30, 2013 and December 31, 2012 of $819,000 and $595,000, respectively. Tax benefits are recorded pursuant to the provisions of ASC 740 “Income Taxes.” If such unrecognized tax benefits are ultimately recorded in any period, the Company’s effective tax rate would be reduced accordingly for such period.

The Company has been examined by the Internal Revenue Service (the “IRS”) through the calendar year 2010. State income tax statutes are generally open for periods back to and including the calendar year 2008.

It is reasonably possible that the Company’s gross unrecognized tax benefits balance may change within the next twelve months due to the expiration of the statutes of limitation of the federal government and various state governments by a range of zero to $38,000. The Company records such unrecognized tax benefits upon the expiration of the applicable statute of limitations or the settlement with tax authorities. As of September 30, 2013, the Company has a liability for unrecognized benefits of $529,000 for federal taxes and $290,000 for state taxes. Such benefits relate primarily to expenses incurred in those jurisdictions.

The Company classifies interest and penalties related to unrecognized tax benefits as income tax expense. At September 30, 2013, and December 31, 2012, the Company has accrued approximately $97,000 and $62,000 for the payment of interest and penalties, respectively.

The final regulations regarding the deduction and capitalization of expenditures related to tangible property were issued during the third quarter of 2013 by the IRS. The Company has reviewed these regulations and does not intend to early adopt or amend any previously filed returns. The implementation of these regulations did not have a material impact on the Company’s consolidated financial statements for the year ending December 31, 2013.

7. Recently Adopted and Issued Accounting Pronouncements

In July 2012, the FASB issued ASU 2012-02 “Intangibles-Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment,” which amends the guidance on impairment testing for indefinite-lived intangible assets. The amended guidance will allow companies to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. A company no longer will be required to test the fair value of an intangible asset unless the company determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. ASU 2012-02 is effective for interim and annual periods beginning after September 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In October 1, 2012, the FASB issued ASU 2012-04 “Technical Corrections and Improvements,” which makes certain technical corrections and improvements and conforming amendments related to fair value measurements. The amendments represent changes to clarify, correct unintended application of, or make minor improvements to the FASB Accounting Standards Codification that are not expected to have a significant effect on current accounting practice. ASU 2012-04 is effective for fiscal periods beginning after December 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

11

In February 2013, the FASB issued ASU No. 2013-02, “Comprehensive Income (Topic 220) – Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety in the same reporting period. ASU 2013-02 is effective for fiscal periods beginning after December 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matter (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity a consensus of the FASB Emerging Issues Task Force,” which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. ASU 2013-05 is effective for fiscal periods beginning after December 15, 2013. The implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force),” which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal periods beginning after December 15, 2013. The implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

8. Goodwill And Intangible Assets

Acquisition in Fiscal 2012

On February 27, 2012, the Company purchased certain assets of Pro-Dex Astromec, Inc. (“Astromec”), a subsidiary of Pro-Dex Inc. (“Pro-Dex”), for approximately $1,050,000, which includes the assumption of liabilities for an estimated earn-out of $294,000. The acquisition was paid for in cash. SL Montevideo Technology, Inc. (“SL-MTI”) recorded direct acquisition costs of approximately $10,000 and $432,000 during the three and nine months ended September 30, 2012, respectively. Direct acquisition costs were recorded within selling, general and administrative expenses in the Consolidated Statements of Income.

12

At December 31, 2012, the financial statements reflected the final purchase price based on estimated fair values at the date of acquisition, including $670,000 in inventories, $202,000 in equipment, and $10,000 in other current assets. The acquisition resulted in intangible assets of $168,000 while no goodwill was recognized. Intangible assets were composed of a customer list with a useful life of 5 years. The purchase price also included $294,000 in liabilities related to an estimated earn-out, which is comprised of quarterly payments based on the performance of the acquired business over the three year period immediately following the date of acquisition. The total liability for the earn-out as of September 30, 2013 and December 31, 2012 was $130,000 and $221,000, respectively. During 2013, $119,000 was paid related to the earn-out. The results from the acquisition date through September 30, 2013 are included in the SL-MTI segment.

Goodwill And Intangible Assets

Intangible assets consist of the following:

		September 30, 2013						December 31, 2012
	Amortizable Life (years)	Gross Value		Accumulated Amortization		Net Value		Gross Value		Accumulated Amortization		Net Value
		(in thousands)
Finite-lived intangible assets:
Customer relationships (1)	5 to 8	$	3,868	$	3,347	$	521	$	3,868	$	3,078	$	790
Patents (2)	5 to 20		1,291		1,211		80		1,285		1,187		98

Licensing fees	5 to 10		450		381		69		450		340		110
Total amortized finite-lived intangible assets			7,309		6,639		670		7,303		6,305		998
Indefinite-lived intangible assets:
Trademarks			1,672		—		1,672		1,672		—		1,672
Other intangible assets, net		$	8,981	$	6,639	$	2,342	$	8,975	$	6,305	$	2,670

(1) On February 27, 2012, the Company purchased certain assets of Astromec, a subsidiary of Pro-Dex. Included in the purchase price is a customer list valued at $168,000. The estimated useful life of the asset is 5 years.

(2) During 2013 and 2012, the Company’s MTE division capitalized legal fees related to a new patent application. The estimated useful life of the asset is 20 years.

In accordance with ASC 350 “Intangibles – Goodwill and Other,” goodwill and other indefinite-lived intangible assets are not amortized, but are tested for impairment. Such impairment testing is undertaken annually, or more frequently upon the occurrence of some indication that an impairment has taken place. The Company conducted an annual impairment test as of December 31, 2012.

A two-step process is utilized to determine if goodwill has been impaired. In the first step, the fair value of each reporting unit is compared to the net asset value recorded for such unit. If the fair value exceeds the net asset value, the goodwill of the reporting unit is not adjusted. However, if the recorded net asset value exceeds the fair value, the Company performs a second step to measure the amount of impairment loss, if any. In the second step, the implied fair value of the reporting unit’s goodwill is compared with the goodwill recorded for such unit. If the recorded amount of goodwill exceeds the implied fair value, an impairment loss is recognized in the amount of the excess.

13

For the testing conducted as of December 31, 2012, the Company concluded that no impairment charge was warranted. Going forward there can be no assurance that economic conditions or other events may not have a negative material impact on the long-term business prospects of any of the Company’s reporting units. In such case, the Company may need to record an impairment loss, as stated above. The next annual impairment test will be conducted as of December 31, 2013, unless management identifies a triggering event in the interim.

Management has not identified any triggering events, as defined by ASC 350, during 2013. Accordingly, no interim impairment test has been performed.

Estimated future amortization expense for intangible assets subject to amortization in each of the next five fiscal years is as follows:

	Amortization Expense (in thousands)
2013	$	440
2014	$	401
2015	$	59
2016	$	40
2017	$	11

Total amortization expense, excluding the amortization of deferred financing costs, consists of amortization expense related to intangible assets and software. Amortization expense related to intangible assets for the three months ended September 30, 2013 and September 30, 2012 was $110,000 and $202,000 respectively. Amortization expense related to intangible assets for the nine months ended September 30, 2013 and September 30, 2012 was $334,000 and $603,000, respectively. Amortization expense related to software for the three months ended September 30, 2013 and September 30, 2012 was $41,000 and $40,000, respectively. Amortization expense related to software for the nine months ended September 30, 2013 and September 30, 2012 was $114,000 and $119,000, respectively.

On August 9, 2012, the Company entered into a Credit Agreement with PNC Bank, National Association, as administrative agent and lender (“PNC Bank”), and the lenders from time to time party thereto, as amended (the “2012 Credit Facility”), to replace its Amended and Restated Revolving Credit Agreement with Bank of America, N.A, as amended (the “2008 Credit Facility”). The 2012 Credit Facility provides for borrowings up to $40,000,000 and under certain conditions maximum borrowings up to $70,000,000. The 2012 Credit Facility included a $5,000,000 sublimit for letters of credit (subsequently amended on March 11, 2013, as described below) and provides for a separate $10,700,000 letter of credit which expires one year from the date of closing, with annual extensions. The 2012 Credit Facility expires on August 9, 2016.

15

Borrowings under the 2012 Credit Facility bear interest, at the Company’s option, at the London interbank offering rate (“LIBOR”) plus a margin rate ranging from 1.25% to 2.0%, or the higher of a Base Rate plus a margin rate ranging from 0.25% to 1.0%. The Base Rate is equal to the highest of (i) the Federal Funds Open Rate plus 0.5% and (ii) the Prime Rate and (iii) the Daily Libor Rate plus 1%. The margin rates are based on certain leverage ratios, as defined. The Company is subject to compliance with certain financial covenants set forth in the 2012 Credit Facility, including, but not limited to, indebtedness to EBITDA, as defined, minimum levels of fixed charges and limitations on capital expenditures, as defined. Availability under the 2012 Credit Facility is based upon the Company’s trailing twelve month EBITDA, as defined.

The Company’s obligations under the 2012 Credit Facility are secured by the grant of security interests in substantially all of its assets.

On March 11, 2013, the Company entered into a First Amendment (the “First Amendment”) to the 2012 Credit Facility. The First Amendment, among other things, (a) amends the Letter of Credit (“LC”) sublimit amount to the lesser of (i) an amount equal to $5,000,000 plus the aggregate amount of Designated Usage LC issued and outstanding under the Designated Usage LC sublimit or (ii) $25,000,000 and (b) allows the Company to enter into foreign currency exchange services with Loan Parties on an unsecured basis and that such obligations shall not exceed at any time an aggregate amount equal to $3,500,000. In consideration for this amendment, the Company incurred $14,000 in fees and expenses, which are amortized over the remaining life of the 2012 Credit Facility.

On May 28, 2013 a letter of credit in the amount of $8,564,000 was issued in favor of the Environmental Protection Agency (“EPA”) to provide financial assurance related to the Company’s environmental payments in accordance with the terms of the Consent Decree reached with the United States Department of Justice (“DOJ”) and EPA related to its liability for both OU-1 and OU-2 (see note 13 for additional information). The letter of credit expires on May 28, 2014 and requires an annual commitment fee of 0.125% and standby commission of 1%, and does not reduce amounts available under the 2012 Credit Facility.

On June 20, 2013, the Company entered into a Second Amendment and Joinder to Credit Agreement and to Security Agreement (the “Second Amendment”), which amends the 2012 Credit Facility in order to reflect the Reincorporation of the Company. The Second Amendment, among other things, joins the Company as a “Borrower” under the Credit Agreement and a “Debtor” under the Security Agreement entered into by SL-NJ in connection with the 2012 Credit Facility. In consideration for the Second Amendment, the Company incurred $28,000 in fees and expenses, which are amortized over the remaining life of the 2012 Credit Facility.

As of September 30, 2013, the Company had an outstanding balance of $3,500,000 under the 2012 Credit Facility. As of December 31, 2012 the Company had no outstanding balance under the 2012 Credit Facility. At September 30, 2013 and December 31, 2012, the Company had total availability under the 2012 Credit Facility of $36,026,000 and $39,510,000, respectively.

13. Commitments and Contingencies

The Company is involved in certain legal and regulatory actions. Management believes that the ultimate resolution of such matters is unlikely to have a material adverse effect on the Company’s financial condition or results of operations, except as described below.

Litigation: The Company has been and is the subject of administrative actions that arise from its ownership of SL Surface Technologies, Inc. (“SurfTech”), a wholly-owned subsidiary, the assets of which were sold in November 2003. SurfTech formerly operated chrome-plating facilities in Pennsauken Township, New Jersey (the “Pennsauken Site”) and Camden, New Jersey (the “Camden Site”).

In 2006 the United States Environmental Protection Agency (the “EPA”) named the Company as a potential responsible party (a “PRP”) in connection with the remediation of the Puchack Well Field, which has been designated as a Superfund Site. The EPA is remediating the Puchack Well Field Superfund Site in two separate operable units. The first operable unit (“OU-1”) consists of an area of chromium groundwater contamination in three aquifers that exceeds the selected cleanup standard. The second operable unit (“OU-2”) pertains to sites that are allegedly the sources of contamination for the first operable unit. The EPA advised the Company in October 2010 that OU-2 includes soil contamination in the immediate vicinity of the Company’s Pennsauken Site.

In June 2011, the EPA announced a proposed plan for “cleaning up the soil” at OU-2. The remedy proposed by the EPA is “Geochemical Fixation.” This remedy involves applying a chemical reductant to the contaminated soil to reduce hexavalent chromium by converting it to immobilized trivalent chromium. The EPA’s estimated cost for this remedy is $20,700,000 over seven years. On September 26, 2011 the EPA issued a Record of Decision (“ROD”) selecting the Geochemical Fixation remedy.

The Company has reached an agreement with both the DOJ and EPA related to its liability for both OU-1 and OU-2 and has entered into a Consent Decree which governs the agreement, the terms of which are described below. The Company has agreed to perform the remediation for OU-2. Also, the Company has agreed to pay a fixed sum for the EPA’s past cost for OU-2 and a portion of the EPA’s past cost for OU-1. The payments are to be made in five equal payments of $2,141,000, for a total $10,705,000, plus interest. The Company has also agreed to pay the EPA’s costs for oversight of the OU-2 remediation. The United States District Court judge signed the Consent Decree effective April 30, 2013, thereby triggering the Company’s obligation under the Consent Decree. On May 10, 2013 the Company made the first payment related to its obligation under the Consent Decree in the amount of $2,185,000, which included interest. The next four payments will be made on the anniversary of the first payment plus ten days in the same amount of $2,141,000, plus interest. On May 28, 2013, a letter of credit in the amount of $8,564,000 was issued in favor of the EPA to provide financial assurance related to the Company’s remaining obligation to pay for the EPA’s past cost as mentioned above. Also, on July 19, 2013 the Company obtained financial assurance as required by the terms of the Consent Decree related to its obligations to remediate OU-2.

18

On December 3, 2012, the Company received a demand letter from the State of New Jersey. The demand is for $1,300,000 for past and future cleanup costs and $500,000 for natural resource damages (“NRD”) for a total of $1,800,000 (the “New Jersey Claim”). Although the Company and its counsel believe that it has meritorious defenses to any claim for reimbursement, the Company has offered to pay $250,000 to fully resolve the claim presented by the State of New Jersey for past costs, future costs and NRD at the Puchack Well Field Superfund site. The State of New Jersey is evaluating the Company’s counter-offer. Based on the current available information, the Company has estimated a total combined potential liability for OU-1 and OU-2 and the New Jersey Claim to be in the range of $17,911,000 to $29,295,000 The Company has recorded an accrual of $17,911,000 related to its combined liability related to this site. The estimated OU-2 remediation liability is based upon the EPA’s plan for remediation as provided in the ROD for OU-2 and the evaluation of data by the Company’s environmental engineering consultants. The liability for OU-1 and OU-2 is based upon the current terms of the Consent Decree.

Other

During 2012, the Company conducted an investigation to determine whether certain employees of SL Xianghe Power Electronics Corporation, SL Shanghai Power Electronics Corporation and SL Shanghai International Trading Corporation, three of the Company’s indirect wholly-owned subsidiaries incorporated and operating exclusively in China, may have improperly provided gifts and entertainment to government officials (the “China Investigation”). The Company had retained outside counsel and forensic accountants to assist in the China Investigation. Based upon the China Investigation, the estimated amounts of such gifts and entertainment were not material to the Company’s financial statements. Such estimates did not take into account the costs to the Company of the China Investigation itself, or any other additional costs.

The China Investigation included determining whether there were any violations of laws, including the U.S. Foreign Corrupt Practices Act (“FCPA”). The Company’s outside counsel contacted the DOJ and the Securities and Exchange Commission (the “SEC”) voluntarily to disclose that the Company was conducting an internal investigation, and agreed to cooperate fully. Additionally, the Company hired outside consultants to provide assistance in implementing a mandatory FCPA compliance program for all of its employees which was completed in December 2012. Also, during the first and second quarters of 2013 the Company engaged outside consultants to perform FCPA compliance tests at its operations in China and Mexico. On September 26, 2013, the DOJ notified the Company that it had closed its inquiry into this matter without filing criminal charges. The Company has not received an update from the SEC regarding the status of its inquiry. The Company cannot predict at this time whether any action may be taken by the SEC.

In the ordinary course of its business the Company is and may be subject to other loss contingencies pursuant to foreign and domestic federal, state and local governmental laws and regulations and may be party to certain legal actions, frequently involving complaints by terminated employees and disputes with customers, suppliers and others. In the opinion of management, any such other loss contingencies are not expected to have a material adverse effect on the financial condition or results of operations of the Company.

19

Environmental Matters: Loss contingencies include potential obligations to investigate and eliminate or mitigate the effects on the environment of the disposal or release of certain chemical substances at various sites, such as Superfund sites and other facilities, whether or not they are currently in operation. The Company is currently participating in environmental assessments and cleanups at a number of sites and in the future may be involved in additional environmental assessments and cleanups. Based upon investigations completed to date by the Company and its independent engineering-consulting firms, management has provided an estimated accrual for all known costs believed to be probable and costs that can be reasonably estimated in the amount of $22,020,000, of which $17,200,000 is included as other long-term liabilities, with the remainder recorded as other short-term accrued liabilities, as of September 30, 2013. However, it is the nature of environmental contingencies that other circumstances might arise, the costs of which are indeterminable at this time due to such factors as changing government regulations and stricter standards, the unknown magnitude of cleanup costs, and the unknown timing and extent of the remedial actions that may be required. These other circumstances could result in additional expenses or judgments, or offsets thereto. The adverse resolution of any one or more of these other circumstances could have a material adverse effect on the business, operating results, financial condition or cash flows of the Company. The Company’s environmental costs primarily relate to discontinued operations and such costs have been recorded in discontinued operations, net of tax.

There are three sites on which the Company may incur material environmental costs in the future as a result of past activities of its former subsidiary, SurfTech. There are two Company owned sites related to its former subsidiary, SurfTech. These sites are located in Pennsauken, New Jersey (the “Pennsauken Site”) and in Camden, New Jersey (the “Camden Site”). There is also a third site, which is not owned by the Company, referred to as the “Puchack Well Field Site.” The Puchack Well Field Site and the Pennsauken Site are part of the Puchack Well Field Superfund Site.

With respect to the Camden Site, the Company has reported soil contamination and a groundwater contamination plume emanating from the site. The New Jersey Department of Environmental Protection (“NJDEP”) approved, and the Company implemented in 2010, an interim remedial action pilot study to inject neutralizing chemicals into the unsaturated soil. Based on an assessment of post-injection data, our consultants believe the pilot study can be implemented as a full scale soil remedy to treat unsaturated contaminated soil. A Remedial Action Workplan for soils (“RAWP”) is being developed. The RAWP will select the injection remedy as the site wide remedy for unsaturated soils, along with demolition and proper disposal of the former concrete building slab and targeted excavation and disposal of impacted soil immediately underlying the slab. Additionally, the RAWP will address a small area of impacted soil off the property. The RAWP will be submitted to the NJDEP, by the Licensed Site Remediation Professional (“LSRP”) for the site. The RAWP is scheduled to be implemented in 2014. Also, the Company’s environmental consultants finalized an interim remedial action pilot study to treat on-site contaminated groundwater, consisting of injecting food-grade product, into the groundwater at the down gradient property boundary, to create a “bio-barrier.” The pilot study includes post-injection monitoring to assess the bio-barrier’s ability to treat contaminated groundwater. Implementation of the groundwater pilot study is currently underway with post-injection effectiveness monitoring expected to continue through 2014.

20

As previously reported, the Company is currently participating in environmental assessments and cleanups at a number of sites. One of these sites is a commercial facility, located in Wayne, New Jersey. Contaminated soil and groundwater has undergone remediation with NJDEP oversight, but contaminants of concern (“COCs”) in groundwater and surface water, which extend off-site, still remain above applicable NJDEP remediation standards. Certain COCs have also been detected in the indoor air of two commercial buildings, located on the property. One of the buildings (the “Main Building”) was outfitted with a sub-slab depressurization system as a mitigation measure. The source investigations under the Main Building were completed in June 2012. Soil and groundwater samples collected from underneath the Main Building identified COCs in excess of the NJDEP’s applicable remediation standards. Consequently, a soil contaminant source remains under the Main Building that is feeding the groundwater contamination. A soil remedial action plan will be required in order to remove the new soil source contamination by a second building that continues to impact groundwater. Our consultants have reviewed data to determine what supplemental remedial action is necessary for soils, and whether to modify or expand the groundwater remedy that will likely consist of additional in-situ injections of food grade product into the groundwater. Estimates have been developed by the Company’s consultants, which includes costs to enhance the existing vapor intrusion system, remedial injections, soil excavation and additional tests and remedial activities. Costs related to this site are recorded as part of discontinued operations, net of tax.

The Company has reported soil and groundwater contamination at the facility of SL-MTI located on its property in Montevideo, Minnesota. An analysis of the contamination has been completed and a remediation plan has been implemented at the site pursuant to the remedial action plan approved by the Minnesota Pollution Control Agency. The remaining steps under this plan are the monitoring of samples. Costs related to this site are recorded as a component of continuing operations.

As of September 30, 2013 and December 31, 2012, environmental accruals of $22,020,000 and $24,367,000, respectively, have been recorded by the Company in accrued liabilities – other and in other long-term liabilities, as appropriate (see Notes 11 and 12 for additional information).

14. Segment Information

The Company currently operates under four business segments: SL Power Electronics Corp. (“SLPE”), the High Power Group, SL-MTI and RFL Electronics Inc. (“RFL”). Teal Electronics Corp. (“TEAL”) and MTE Corporation (“MTE”) are combined into one business segment, which is reported as the High Power Group. The Company aggregates operating business subsidiaries into a single segment for financial reporting purposes if aggregation is consistent with the objectives of ASC 280 “Segment Reporting.” Business units are also combined if they have similar characteristics in each of the following areas:

• nature of products and services

• nature of production process

• type or class of customer

• methods of distribution

21

SLPE designs, manufactures and markets high-reliability power conversion products in internal and external footprints. The Company’s power supplies provide a reliable and safe power source for the customer’s specific equipment needs. SLPE, which sells products under three brand names (SL Power Electronics, Condor and Ault), is a major supplier to the original equipment manufacturers (“OEMs”) of medical, industrial/instrumentation, military and information technology equipment. The High Power Group sells products under two brand names (TEAL and MTE). TEAL designs and manufactures custom power conditioning and distribution units for OEMs of medical imaging, medical treatment, military aerospace, semiconductor, solar and advanced simulation systems. MTE designs and manufactures power quality products used to protect equipment from power surges, bring harmonics into compliance and improve the efficiency of variable speed motor drive systems. SL-MTI designs and manufactures high power density precision motors that are used in numerous applications, including military and commercial aerospace, oil and gas, and medical and industrial products. RFL designs and manufactures communication and power protection products/systems that are used to protect electric utility transmission lines and apparatus by isolating faulty transmission lines from a transmission grid. The Unallocated Corporate Expenses segment includes corporate related items, financing activities and other costs not allocated to reportable segments, which includes but is not limited to certain treasury, risk management, legal, litigation and public reporting charges and certain legacy costs. The accounting policies for the business units are the same as those described in the summary of significant accounting policies. For additional information, see Note 1 of the Notes to the Consolidated Financial Statements included in Part IV of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Business segment operations are conducted through domestic subsidiaries. For all periods presented, sales between business segments were not material. Each of the segments has certain major customers, the loss of any of which would have a material adverse effect on such segment.

15. Retirement Plans And Deferred Compensation

During the nine months ended September 30, 2013 and September 30, 2012, the Company maintained a defined contribution pension plan covering all full-time, U.S. employees of SLPE, the High Power Group, including TEAL and MTE, SL-MTI, RFL, and the corporate office. The Company’s contributions to this plan are based on a percentage of employee contributions and/or plan year gross wages, as defined. Costs incurred under these plans amounted to $179,000 and $576,000 during the three month and nine month periods ended September 30, 2013 compared to $181,000 and $614,000 during the three month and nine month periods ended September 30, 2012.

The Company has agreements with certain retired directors, officers and key employees providing for supplemental retirement benefits. The liability for supplemental retirement benefits is based on the most recent mortality tables available and discount rates ranging from 6% to 12%. The amount charged to expense in connection with these agreements amounted to $91,000 and $223,000 for the three month and nine month periods ended September 30, 2013 compared to $64,000 and $265,000 for the three month and nine month periods ended September 30, 2012.

16. Discontinued Operations

For the three and nine months ended September 30, 2013, total loss from discontinued operations before income taxes was $463,000 and $1,211,000 ($282,000 and $737,000, net of tax). For the three and nine months ended September 30, 2012, total loss from discontinued operations before income taxes was $764,000 and $1,478,000 ($464,000 and $902,000, net of tax), respectively. The loss from discontinued operations during 2013 and 2012 relates to environmental remediation costs, consulting fees, and legal expenses associated with the past operations of the Company’s five environmental sites (See Note 13 – Commitments and Contingencies for further information concerning the environmental sites).

17. Fair Value Measurement and Financial Instruments

ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. FASB ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances.

ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, FASB ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

24

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Currently, the Company uses foreign currency forward contracts to hedge its foreign currency risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including spot rates and market forward points. The fair value of the foreign currency forward contracts is based on interest differentials between the currencies being traded, spot rates and market forward points.

To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees, where applicable.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

In conjunction with its implementation of updates to the fair value measurements guidance, the Company made an accounting policy election to measure derivative financial instruments subject to master netting agreements on a net basis.

During the third quarter of 2013, the Company purchased publicly traded equity securities which are classified as available-for-sale securities. Fair values for these investments are based on closing stock prices from active markets for identical assets and therefore are classified within Level 1 of the fair value hierarchy. The fair value of available-for-sale securities is included in other current assets in the Company’s Consolidated Balance Sheets.

25

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis as of September 30, 2013 and December 31, 2012, aggregated by the level in the fair value hierarchy within which those measurements fall:

	Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance at September 30, 2013
	(in thousands)
Assets

Derivative financial instruments	$	—	$	105	$	—	$	105
	Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance at December 31, 2012
	(in thousands)
Assets
Derivative financial instruments	$	—	$	243	$	—	$	243

The Company does not have any fair value measurements using significant unobservable inputs (Level 3) as of September 30, 2013 and December 31, 2012.

Credit Risk Contingent Features

The Company has agreements with its derivative counterparties that contain a provision where if the Company defaults or is capable of being declared in default on any of its indebtedness, then the Company could also be declared in default on its derivative obligations.

18. Derivative Instruments and Hedging Activities

ASC Topic 815, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC Topic 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows related to forecasted foreign exchange-based risk are considered economic hedges of the Company’s forecasted cash flows.

Risk Management Objective of Using Derivatives

The Company is a U.S. dollars (USD) functional currency entity that manufactures products in the USA, Mexico and China. The Company’s sales are priced in USD and its costs and expenses are priced in USD, Mexican pesos (MXN) and Chinese Yuan (CNH). As a result, the Company has exposure to changes in exchange rates between the time when expenses in the non-functional currencies are initially incurred and the time when the expenses are ultimately paid. The Company’s objective in using derivatives is to add stability and to manage its exposure to foreign exchange risks. To accomplish this objective, the Company uses foreign currency forward contracts to manage its exposure to fluctuations in the exchange rates. Foreign currency forward contracts involve fixing the USD-MXN and USD-CNH exchange rates for delivery of a specified amount of foreign currency on a specified date.

26

During 2012 and 2013, the Company entered into a series of foreign currency forward contracts to hedge its exposure to foreign exchange rate movements in its forecasted expenses in China and Mexico. The foreign currency forwards are not speculative and are being used to manage the Company’s exposure to foreign exchange rate movements. Foreign currency forward contracts involve fixing the USD-MXN and USD-CNH exchange rates for delivery of a specified amount of foreign currency on a specified date. The Company has elected not to apply hedge accounting to these derivatives and they are marked to market through earnings. Therefore, gains and losses resulting from changes in the fair value of these contracts are recognized at the end of each reporting period directly in earnings. The gains and losses associated with the foreign currency forward contracts are included in other gain (loss), net on the Consolidated Statements of Income. As of September 30, 2013, the fair value of the foreign currency forward contracts was recorded as a $105,000 liability in other current liabilities on the Consolidated Balance Sheets. As of December 31, 2012, the fair value of the foreign currency forward contracts was recorded as a $243,000 asset in other current assets on the Consolidated Balance Sheets.

Non-designated Hedges of Foreign Exchange Risk

The notional amounts are used to measure the volume of foreign currency forward contracts and do not represent exposure to foreign currency losses. The following table summarizes the notional values of the Company’s derivative financial instruments as of September 30, 2013.

Product	Number of Instruments		Notional
			(in thousands)
Mexican Peso (MXN) Forward Contracts		18	MXN	72,392
Chinese Yuan (CNH) Forward Contracts		17	CNH	89,843

The following table details the location in the financial statements of the gain or loss recognized on foreign currency forward contracts that are marked to market for the three and nine months ended September 30, 2013 and September 30, 2012:

19. Foreign Operations

As a result of a work stoppage at the Company’s Xianghe manufacturing facilities from March 7, 2013 through March 20, 2013, revenues for the quarter ended March 31, 2013 were adversely impacted by approximately $900,000. The Company realized those sales during the second quarter of 2013. Additionally, certain incremental costs were incurred during the nine months ended September 30, 2013 related to the work stoppage, including employee, travel, consulting and legal costs of $662,000.

20. Shareholders’ Equity

On November 16, 2010, the Board of Directors authorized a plan that allows for the repurchase up to an aggregate of 470,000 shares of the Company’s outstanding common stock (the “2010 Repurchase Plan”). Any repurchases pursuant to the 2010 Repurchase Plan would be made in the open market or in negotiated transactions. During the first nine months of 2013, the Company purchased approximately 76,000 shares of Company stock at an average price of $23.90 a share. As a result, as of September 30, 2013, approximately 254,000 shares remained available for purchase under the 2010 Repurchase Plan.

21. Related Party Transactions

On May 1, 2013, the Company entered into a Management Services Agreement (“Management Services Agreement”) with SP Corporate Services LLC (“SP Corporate”). SP Corporate is an affiliate of SPH Group Holdings LLC (“SPHG”). A member of the Company’s Board of Directors, Warren G. Lichtenstein, is affiliated with SPHG. Also, the Company’s Chairman of the Board, Glen M. Kassan is affiliated with SPHG. Pursuant to the Management Services Agreement, SP Corporate agreed to provide, at the direction of the Company’s Chief Executive Officer, non-exclusive services to support the Company’s growth strategy, business development, planning, execution assistance and related support services. The monthly fee for these services is $10,400 paid in advance. The Management Services Agreement has a term of one year and has been approved by the Audit Committee of the Board of Directors and a majority of the disinterested directors of the Company.

The Company intends to focus on improving efficiencies that better leverage the Company’s resources. Lean initiatives, both on the factory floor and throughout the organization, are ongoing. The Company expects to pursue its goals during the next twelve months principally through organic growth. The Company also continues to pursue strategic alternatives to maximize shareholder value. Some of these alternatives have included, and could continue to include, selective acquisitions, divestitures and the sale of certain assets. The Company has provided, and may from time to time in the future provide, information to interested parties.

In the sections that follow, statements with respect to the quarter ended 2013 or nine months ended 2013 refer to the three month and nine month periods ended September 30, 2013. Statements with respect to the quarter ended 2012 or nine months ended 2012 refer to the three month and nine month periods ended September 30, 2012. Also, statements with respect to operating costs refer to engineering and product development costs, selling, general and administrative costs and depreciation and amortization (“operating costs”).

Significant Transactions and Financial Trends

As a result of a work stoppage at the Company’s Xianghe manufacturing facilities from March 7, 2013 through March 20, 2013, revenues for the quarter ended March 31, 2013 were adversely impacted by approximately $900,000. The Company realized those sales during the second quarter of 2013. Additionally, certain incremental costs were incurred during the nine months ended September 30, 2013 related to the work stoppage, including employee, travel, consulting and legal costs of $662,000.

On March 11, 2013, the Company entered into a First Amendment (the “First Amendment”) to the senior revolving credit facility (the “2012 Credit Facility”) with PNC Bank, National Association (“PNC Bank”). The First Amendment, among other things, (a) amends the Letter of Credit (“LC”) sublimit amount to the lesser of (i) an amount equal to $5,000,000 plus the aggregate amount of Designated Usage LC issued and outstanding under the Designated Usage LC sublimit or (ii) $25,000,000 and (b) allows the Company to enter into foreign currency exchange services with Loan Parties on an unsecured basis and that such obligations shall not exceed at any time an aggregate amount equal to $3,500,000 (See Note 10 – Debt for terms and conditions of the 2012 Credit Facility).

On May 9, 2013, the Company’s shareholders voted to approve a proposal to change the state of incorporation of SL Industries from the State of New Jersey to the State of Delaware by merging SL Industries, Inc., a New Jersey corporation (“SL-NJ”) with and into SL Industries, Inc., a Delaware corporation (“SL-DE”) (the “Reincorporation”). On June 20, 2013 (the “Effective Date”), the Reincorporation was effected by merging SL-NJ with and into SL-DE pursuant to an Agreement and Plan of Merger, dated June 3, 2012, between SL-NJ and SL-DE. SL-DE survived the merger and SL-NJ ceased to exist. The principal reason for the Reincorporation was to give the Company a greater measure of flexibility and simplicity in corporate governance and provide greater clarity and predictability with respect to the Company’s corporate legal affairs. The Reincorporation did not result in any change in the name, business, management, fiscal year, accounting, location of the principal executive officers, assets or liabilities or net worth (other than the costs of reincorporation which were immaterial) of the Company.

30

On June 20, 2013, the Company entered into a Second Amendment and Joinder to Credit Agreement and to Security Agreement (the “Second Amendment”), which amends the 2012 Credit Facility in order to reflect the Reincorporation of the Company. The Second Amendment, among other things, joins the Company as a “Borrower” under the Credit Agreement and a “Debtor” under the Security Agreement entered into by SL-NJ in connection with the 2012 Credit Facility.

Business Trends

Demand for the Company’s products and services increased during 2013 compared to 2012. Sales for the nine months ended September 30, 2013, increased by $2,755,000, or 2%, and income from operations increased by $4,072,000, or 49%.

Sales increased during the nine months ended September 30, 2013 due to an increase at the High Power Group, which was partially offset by decreases at RFL Electronics Inc. (“RFL”) and Montevideo Technology, Inc. (“SL-MTI”). SL Power Electronics Corp. (“SLPE”) remained relatively flat during 2013. The increase in sales at the High Power Group was due to an increase at MTE Corporation (“MTE”), which was partially offset by a decrease at Teal Electronics Corp. (“TEAL”).

Income from operations increased during the nine months ended September 30, 2013 due to increases at SLPE, the High Power Group, and RFL, which was partially offset by a decrease at SL-MTI. Unallocated Corporate Expenses remained flat during 2013 compared to 2012. The increase in income from operations at the High Power Group was due to an increase at MTE, which was partially offset by a decrease at TEAL.

During the nine months ended September 30, 2013, the Company’s backlog increased to $66,909,000, from $64,608,000 for the same period in the prior year, for a change of 4% on a comparative basis. The increase in backlog in 2013 was primarily attributable to SL-MTI, who recorded a 20% increase in backlog. The increase in backlog at SL-MTI was partially offset by decreases at RFL, SLPE and the High Power Group of 26%, 7%, and 3%, respectively. The Company’s net new orders for the nine months ended September 30, 2013 increased by 4%, compared to the nine months ended September 30, 2012.

The Company’s management is taking numerous actions to improve sales through the deployment of numerous growth tools aimed at identifying attractive market segments and penetrating those markets through aggressive new product introduction. The Company is also identifying and penetrating selected geographic opportunities. The Company is continuing to emphasize lean initiatives at all of its facilities in manufacturing as well as in the transactional and reporting processes. The Company also continues to pursue strategic alternatives to maximize shareholder value. Some of these alternatives have included, and could continue to include, selective acquisitions, divestitures and the sale of certain assets.

While these items are important in understanding and evaluating financial results and trends, other transactions or events, which are disclosed in this Management’s Discussion and Analysis, may have a material impact on continuing operations. A complete understanding of these transactions is necessary in order to estimate the likelihood that these trends will continue.

Critical Accounting Policies

The Company’s consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles in the United States (“GAAP”). GAAP requires management to make estimates and assumptions that affect the amounts of reported and contingent assets and liabilities at the date of the consolidated financial statements and the amounts of reported net sales and expenses during the reporting period.

The SEC has issued disclosure guidance for “critical accounting policies.” The SEC defines “critical accounting policies” as those that are most important to the portrayal of the Company’s financial condition and results, and that require application of management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods.

The Company’s significant accounting policies are described in Note 1 in the Notes to Consolidated Financial Statements included in Part IV of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Not all of these significant accounting policies require management to make difficult, subjective or complex judgments or estimates. However, the following policies are deemed to be critical within the SEC definition. The Company’s senior management has reviewed these critical accounting policies and estimates and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations with the Audit Committee of the Board of Directors.

Revenue Recognition

Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the purchase price is fixed or determinable and collectability is reasonably assured. Revenue is recorded in accordance with Staff Accounting Bulletin (“SAB”) No. 104 and in certain circumstances in accordance with the guidance provided by ASC 605-25 “Revenue Recognition – Multiple-Element Arrangements.” The major portion of the Company’s revenue is derived from equipment sales. The Company recognizes equipment revenue upon shipment or delivery, depending upon the terms of the order, and transfer of title. Generally, the revenue recognition criteria is met at the time the product is shipped. Provisions are established for product warranties, principally based on historical experience. At times the Company establishes reserves for specific warranty issues known by management. Customer service and installation revenue is recognized when completed. RFL has customer service revenue, which accounted for less than one percent of consolidated net revenue for the nine months ended 2013 and 2012.

SLPE has two sales programs with distributors, pursuant to which credits are issued to distributors: (1) a re-stocking program and (2) a competitive discount program. The distributor re-stocking program allows distributors to rotate up to a pre-determined percentage of their purchases over the previous nine month period. SLPE provides for this allowance as a decrease to revenue based upon the amount of sales to each distributor and other historical factors. The competitive discount program allows a distributor to sell a product out of its inventory at a negotiated price in order to meet certain competitive situations. SLPE records this discount as a reduction to revenue based on the distributor’s eligible inventory. The eligible distributor inventory is reviewed at least quarterly. No cash is paid under either distributor program. These programs affected consolidated gross revenue for each of the nine month periods ended 2013 and 2012 by approximately 0.5% and 0.7%, respectively.

32

Certain judgments affect the application of the Company’s revenue policy, as mentioned above. Revenue recognition is significant because net revenue is a key component of results of operations. In addition, revenue recognition determines the timing of certain expenses, such as commissions, royalties and certain incentive programs. Revenue results are difficult to predict. Any shortfall in revenue or delay in recognizing revenue could cause operating results to vary significantly from year to year and quarter to quarter.

Allowance For Doubtful Accounts

The Company’s estimate for the allowance for doubtful accounts related to trade receivables is based on two methods. The amounts calculated from each of these methods are combined to determine the total amount reserved. First, the Company evaluates specific accounts where it has information that the customer may have an inability to meet its financial obligations (e.g., bankruptcy or insolvency). In these cases, the Company uses its judgment, based on the best available facts and circumstances, and records a specific reserve for that customer against amounts due to reduce the receivable to the amount that is expected to be collected. These specific reserves are reevaluated and adjusted as additional information is received that impacts the amount reserved. Second, a general reserve is established for all customers based on several factors, including historical write-offs as a percentage of sales. If circumstances change (e.g., higher than expected defaults or an unexpected material adverse change in a major customer’s ability to meet its financial obligation), the Company’s estimates of the recoverability of amounts due could be reduced by a material amount. Receivables are charged off against the reserve when they are deemed uncollectible. The Company’s allowance for doubtful accounts equaled 1.9% and 2.0% of gross trade receivables as of September 30, 2013 and December 31, 2012.

Inventories

The Company values inventory at the lower of cost or market, and continually reviews the book value of discontinued product lines to determine if these items are properly valued. The Company identifies these items and assesses the ability to dispose of them at a price greater than cost. If it is determined that cost is less than market value, then cost is used for inventory valuation. If market value is less than cost, then related inventory is adjusted to market value.

If a write down to the current market value is necessary, the market value cannot be greater than the net realizable value, which is defined as selling price less costs to complete and dispose, and cannot be lower than the net realizable value less a normal profit margin. The Company also continually evaluates the composition of its inventory and identifies obsolete, slow-moving and excess inventories. Inventory items identified as obsolete, slow-moving or excess are evaluated to determine if reserves are required. If the Company were not able to achieve its expectations of the net realizable value of the inventory at current market value, it would have to adjust its reserves accordingly. The Company attempts to accurately estimate future product demand to properly adjust inventory levels. However, significant unanticipated changes in demand could have a significant impact on the value of inventory and of operating results.

33

Investments

The Company determines the appropriate classification of its investments in equity securities at the time of purchase and reevaluates such determinations at each balance sheet date. Marketable securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities and are reported at fair value, with unrealized gains and losses recognized in earnings. Marketable equity securities not classified as trading are classified as available for sale, and are carried at fair market value, with the unrealized gains and losses, net of tax, included in the determination of comprehensive income and reported in shareholders’ equity.

The fair value of substantially all securities is determined by quoted market prices. The estimated fair value of securities for which there are no quoted market prices is based on similar types of securities that are traded in the market.

Derivative Instruments and Hedging Activities

FASB ASC 815, “Derivatives and Hedging” (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. Certain of the Company’s foreign operations expose the Company to fluctuations of foreign interest rates and exchange rates. These fluctuations may impact the value of the Company’s revenues, expenses, cash receipts and payments in terms of the Company’s functional currency. The Company enters into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure.

As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. Currently, the Company does not apply hedge accounting to any of its foreign currency derivatives.

34

Accounting For Income Taxes

Significant management judgment is required in determining the provision for income taxes, deferred tax assets and liabilities and any valuation allowance recorded against deferred tax assets. Net deferred tax assets as of September 30, 2013 and December 31, 2012 were $12,942,000 and $13,134,000, respectively, net of valuation allowances of $2,008,000 and $1,987,000 (mostly related to discontinued operations) as of September 30, 2013 and December 31, 2012, respectively. The carrying value of the Company’s net deferred tax assets assumes that the Company will be able to generate sufficient future taxable income in certain tax jurisdictions. Valuation allowances are attributable to uncertainties related to the Company’s ability to utilize certain deferred tax assets prior to expiration. These deferred tax assets primarily consist of certain federal and state tax expenses, research and development tax credits, and loss carryforwards. The valuation allowance is based on estimates of taxable income, expenses and credits by the jurisdictions in which the Company operates and the period over which deferred tax assets will be recoverable. In the event that actual results differ from these estimates or these estimates are adjusted in future periods, the Company may need to establish an additional valuation allowance that could materially impact its consolidated financial position and results of operations. Each quarter, management evaluates the ability to realize the deferred tax assets and assesses the need for additional valuation allowances.

The Company applies the provisions of ASC 740-10-55 to all tax positions for which the statute of limitations remain open. The amount of gross unrecognized tax benefits, excluding interest and penalties, as of September 30, 2013 and December 31, 2012 was $819,000 and $595,000, respectively. This amount represents unrecognized tax benefits, which, if ultimately recognized, will reduce the Company’s effective tax rate. As of September 30, 2013 and December 31, 2012, the Company reported accrued interest and penalties related to unrecognized tax benefits of $97,000 and $62,000, respectively. For additional disclosures related to accounting for income taxes, see Note 10 in the Notes to the Consolidated Financial Statements included in Part IV of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Legal Contingencies

The Company is currently involved in certain legal proceedings. As discussed in Note 13 of the Notes to the Consolidated Financial Statements included in Part I of this Quarterly Report on Form 10-Q, the Company has accrued an estimate of the probable costs for the resolution of these claims. This estimate has been developed based on the current stage of negotiations and data from the Company’s environmental engineering consultants. Management does not believe these proceedings will have a further material adverse effect on the Company’s consolidated financial position, except as discussed in Note 13. As with litigation, generally the outcome is inherently uncertain. It is possible, however, that future results of operations for any particular quarterly or annual period could be materially affected by changes in these assumptions, or the effectiveness of these strategies, related to these proceedings.

35

Goodwill

The Company has allocated its adjusted goodwill balance to its reporting units. The Company tests goodwill for impairment annually at fiscal year-end and in interim periods if certain events occur indicating that the carrying value of goodwill may be impaired, such as a significant adverse change in business climate, an adverse action or assessment by a regulator or the decision to sell a business, that would make it more likely than not that an impairment may have occurred. The goodwill impairment test is a two-step process. The first step of the impairment analysis compares the fair value to the net book value. In determining fair value, the accounting guidance allows for the use of several valuation methodologies, although it indicates that quoted market prices are the best evidence of fair value. The Company uses a combination of expected present values of future cash flows and comparative market multiples. It has also performed a review of market capitalization with estimated control premiums at December 31, 2012. If the fair value of a reporting unit is less than its net book value, the Company would perform a second step in its analysis, which compares the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, the Company recognizes an impairment loss equal to that excess amount. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units and determining the fair value of each reporting unit. Significant judgments required to estimate the fair value of reporting units include estimating future cash flows, determining appropriate discount and growth rates, operating margins and working capital requirements, selecting comparable companies within each reporting unit and market and determining control premiums. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit. There were no impairment charges for the nine months ended 2013 and 2012. As of September 30, 2013 and December 31, 2012, goodwill totaled $22,723,000 and $22,735,000 (representing 19% and 21% of total assets), respectively.

As of the testing conducted as of December 31, 2012, the Company concluded that no impairment charge was warranted. However, there can be no assurance that the economic conditions currently affecting the world economy or other events may not have a negative material impact on the long-term business prospects of any of the Company’s reporting units. In such case, the Company may need to record an impairment loss, as stated above. The next annual impairment test will be conducted as of December 31, 2013, unless management identifies a triggering event in the interim.

Management has not identified any triggering events, as defined by ASC 350 “Intangibles – Goodwill and Other,” during 2013. Accordingly, no interim impairment test has been performed.

Impairment Of Long-Lived And Intangible Assets

The Company’s long-lived and intangible assets primarily consist of fixed assets, goodwill and other intangible assets. The Company periodically reviews the carrying value of its long-lived assets held and used, other than goodwill and intangible assets with indefinite lives, and assets to be disposed of whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses the recoverability of the asset by estimated cash flows and at times by independent appraisals. It compares estimated cash flows expected to be generated from the related assets, or the appraised value of the asset, to the carrying amounts to determine whether impairment has occurred. If the estimate of cash flows expected to be generated changes in the future, the Company may be required to record impairment charges that were not previously recorded for these assets. If the carrying value of a long-lived were not previously recorded for these assets. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value. Asset impairment evaluations are by nature highly subjective.

36

Environmental Expenditures

The Company is subject to United States, Mexican, Chinese and United Kingdom environmental laws and regulations concerning emissions to the air, discharges to surface and subsurface waters, and generation, handling, storage, transportation, treatment and disposal of waste materials. The Company is also subject to other federal, state and local environmental laws and regulations, including those that require it to remediate or mitigate the effects of the disposal or release of certain chemical substances at various sites, mostly at sites where the Company has ceased operations. It is impossible to predict precisely what effect these laws and regulations will have in the future.

Expenditures that relate to current operations are charged to expense or capitalized, as appropriate. Expenditures that relate to an existing condition caused by formerly owned operations are expensed and recorded as part of discontinued operations, net of tax. Expenditures include costs of remediation, consulting, legal fees to defend against claims for environmental liability and certain costs to assist the Company with compliance matters and administrative tasks. Liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. The liability for remediation expenditures includes, as appropriate, elements of costs such as site investigations, consultants’ fees, feasibility studies, outside contractor expenses, monitoring expenses, and certain potential claims. Estimates are not discounted and they are not reduced by potential claims for recovery from insurance carriers. The Company does not currently have any outstanding claims against insurance carriers related to remediation expenditures. The liability is periodically reviewed and adjusted to reflect current remediation progress, prospective estimates of required activity and other relevant factors, including changes in technology or regulations. For additional information related to environmental matters, see Note 15 of the Notes to the Consolidated Financial Statements included in Part IV of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 and Note 13 to this Quarterly Report.

The above listing is not intended to be a comprehensive list of all of the Company’s accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP with no need for management’s judgment in its application. There are also areas in which management’s judgment in selecting any available alternatives would not produce a materially different result. For a discussion of accounting policies and other disclosures required by GAAP, see the Company’s audited Consolidated Financial Statements and Notes thereto included in Part IV of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 and Part 1 to this Quarterly Report.

Liquidity And Capital Resources

	September 30, 2013		December 31, 2012		$ Variance			% Variance
	(in thousands)
Cash and cash equivalents	$	2,032	$	3,196	$	(1,164	)		(36	%)
Bank debt	$	3,500	$	—	$	3,500			100	%
Working capital	$	31,669	$	26,309	$	5,360			20	%
Shareholders’ equity	$	57,976	$	50,432	$	7,544			15	%

The Company’s liquidity needs have related to, and are expected to continue to relate to, capital investments, product development costs, acquisitions, working capital requirements, and certain environmental and legal remediation costs. The Company has met its liquidity needs primarily through cash generated from operations and, to a lesser extent, through bank borrowings. The Company believes that cash provided by operating activities from continuing operations and funding available under the 2012 Credit Facility will be adequate to service debt and meet working capital needs, capital investment requirements, and product development requirements for the next twelve months.

At September 30, 2013, the Company reported $2,032,000 of cash, compared to $3,196,000 of cash and cash equivalents as of December 31, 2012. Cash and cash equivalents decreased in 2013 primarily due to $5,126,000 of cash used in investing activities and $3,607,000 of cash used in operating activities from discontinued operations, which were partially offset by $5,136,000 of cash provided by operating activities from continuing operations and $2,406,000 of cash provided by financing activities.

Cash used in operating activities from discontinued operations during the nine month period ended September 30, 2013 was $3,607,000 as compared to cash used in operating activities from discontinued operations of $780,000 during the nine month period ended September 30, 2012. Cash used in operating activities from discontinued operations during 2013 was primarily related to a payment of $2,185,000, which included interest, for the EPA’s past cost for OU-2 and a portion of the EPA’s past cost for OU-1 according to the terms set forth in the Consent Decree (See Note 13 – Commitments and Contingencies for the terms and conditions of the Consent Decree). The remaining payments in 2013 and the payments in 2012 were related to environmental remediation costs, consulting fees, and legal expenses associated with the past operations of the Company’s five environmental sites.

Net cash provided by operating activities from continuing operations during the nine month period ended September 30, 2013 was $5,136,000 as compared to net cash provided by operating activities from continuing operations of $6,351,000 during the nine month period ended September 30, 2012. The primary sources of cash from operating activities for the nine month period ended September 30, 2013 were income from continuing operations of $8,670,000 and an increase in other accrued liabilities of $2,343,000. In addition, depreciation and amortization expense of $1,793,000 was added to income from continuing operations. The largest increase in other accrued liabilities occurred at SLPE. The increase at SLPE was primarily due to an increase in accrued bonus and other compensation, an increase in accrued U.S. agency fees, and an increase in the warranty reserve. The sources of cash from operating activities were partially offset by an increase in inventory of $3,568,000, an increase in accounts receivable of $3,339,000,

38

and an increase in other assets of $823,000. The largest increases in inventory occurred at The High Power Group and SLPE. The increase at the High Power Group was primarily due to an increase at TEAL due to the cancellation of a large solar customer order (cost recovery negotiations are underway) coupled with the delay of customer shipments temporarily held at the Mexican border, which were shipped in October 2013. The increase at SLPE was primarily due to the delay of a large customer shipment until the fourth quarter of 2013. The largest increases in accounts receivable occurred at SL-MTI and SLPE. The increase at SL-MTI was primarily due to an increase in sales during the third quarter of 2013 as compared to relatively low sales in the fourth quarter of 2012 coupled with the delay of two large customer receipts until October 2013. The increase at SLPE was primarily due to an increase in international sales during the third quarter of 2013 as compared to the fourth quarter of 2012. The increase in other assets was primarily due to the timing of certain insurance premiums paid during the first half of 2013 and an increase in prepaid taxes. The increase in other assets was also due to an increase in payments related to purchase agreements for copper at the High Power Group.

Net cash provided by operating activities from continuing operations during the nine month period ended September 30, 2012 was $6,351,000. The sources of cash from operating activities for the nine month period ended September 30, 2012 were income from continuing operations of $5,719,000, the add-back of depreciation and amortization expense of $2,038,000, and the add-back of non-cash stock compensation expense of $909,000. These sources of cash from operating activities were partially offset by an increase in accounts receivable of $1,237,000 and an increase in other assets of $542,000. The largest increases in accounts receivable occurred at SL-MTI and at the High Power Group, which were partially offset by a large decrease at RFL. The increase at SL-MTI was due to increased sales during the third quarter of 2012 coupled with a large customer payment which was not received until October 2012. The increase at the High Power Group was primarily due to an increase at TEAL due to increased sales during the third quarter of 2012 coupled with two large customer payments which were not received until October 2012. The decrease at RFL was primarily due to decreased sales during 2012. The increase in other assets was due primarily to the capitalization of financing costs to replace the 2008 Credit Facility with the new 2012 Credit Facility and the timing of certain insurance premiums paid during the first half of 2012.

Net cash used in investing activities during the nine month period ended September 30, 2013 was $5,126,000 as compared to net cash used in investing activities of $2,390,000 during the nine month period ended September 30, 2012. Cash used in investing activities during 2013 was for the purchases of property, plant and equipment of $2,541,000, the purchases of common stock classified as available-for-sale securities of $2,362,000, and for the purchase of other assets of $223,000. Purchases of property, plant and equipment were primarily used to upgrade production capabilities and technology, to acquire new production equipment in Mexico, and to acquire demonstration equipment related to new product introductions. Purchases of other assets were primarily related to the purchase of software. Cash used in investing activities during 2012 was for the purchases of property, plant and equipment of $1,432,000, the acquisition of certain assets of a business of $756,000, and for the purchase of other assets of $202,000. Purchases of property, plant and equipment were primarily used to upgrade production capabilities and technology. Purchases of other assets were primarily related to the purchase of software and the capitalization of legal fees related to a new patent application at MTE.

39

On February 27, 2012, the Company purchased certain assets of Pro-Dex Astromec, Inc. (“Astromec”), a subsidiary of Pro-Dex Inc. (“Pro-Dex”), for approximately $1,050,000, which includes the assumption of liabilities for an estimated earn-out of $294,000. The earn-out is comprised of quarterly payments based on the performance of the acquired business over the three year period immediately following the date of acquisition. The acquisition was paid in cash.

Net cash provided by financing activities during the nine month period ended September 30, 2013 was $2,406,000 as compared to net cash used in financing activities of $7,046,000 during the nine month period ended September 30, 2012. Cash provided by financing activities during 2013 was primarily related to $3,500,000 of net borrowings under the 2012 Credit Facility and $631,000 of proceeds from the stock option exercises, which were partially offset by the purchase of Company stock pursuant to the Company’s 2010 Repurchase Plan (described in Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds) in the amount of $1,803,000. Cash used in financing activities during 2012 was primarily related to the repurchase and retirement of common stock pursuant to the Company’s Tender Offer and the purchase of Company stock pursuant to the Company’s 2010 Repurchase Plan.

On August 9, 2012, the Company entered into the 2012 Credit Facility with PNC Bank to replace its Amended and Restated Revolving Credit Agreement with Bank of America, N.A., as amended (the “2008 Credit Facility”). The 2012 Credit Facility provides for borrowings up to $40,000,000 and under certain conditions maximum borrowings up to $70,000,000. The 2012 Credit Facility included a $5,000,000 sublimit for letters of credit (subsequently amended on March 11, 2013) and provides for a separate $10,700,000 letter of credit which expires one year from the date of closing, with annual extensions. The 2012 Credit Facility expires on August 9, 2016 (See Note 10 – Debt for the terms and conditions of the 2012 Credit Facility).

As of September 30, 2013, the Company had an outstanding balance of $3,500,000 under the 2012 Credit Facility. As of December 31, 2012, the Company had no outstanding balance under the 2012 Credit Facility. At September 30, 2013 and December 31, 2012, the Company had total availability under the 2012 Credit Facility of $36,026,000 and $39,510,000, respectively. The Company’s percentage of total debt to total shareholders’ equity was 6.0% as of September 30, 2013.

The Company’s current ratio was 1.81 to 1 at September 30, 2013 and 1.76 to 1 at December 31, 2012. Current assets increased by $9,544,000 from December 31, 2012, while current liabilities increased by $4,184,000 during the same period.

Capital expenditures were $2,541,000 in 2013, which represented an increase of $1,109,000 from the capital expenditure levels of 2012. The Company anticipates spending approximately $997,000 on property, plant and equipment, used primarily to upgrade production capabilities and upgrade technology, during the remainder of 2013. The 2013 capital additions are expected to be funded primarily through cash from operating activities.

40

With the exception of the segment reported as “Unallocated Corporate Expenses” (which consists primarily of corporate office expenses, financing activities, certain treasury, risk management, legal, litigation, public reporting costs, legacy costs and costs not specifically allocated to the reportable business segments), all of the Company’s operating segments recorded income from operations for the nine months ended September 30, 2013.

Contractual Obligations

The following is a summary of the Company’s contractual obligations at September 30, 2013 for the periods indicated:

	Less Than 1 Year		1 to 3 Years		3 to 5 Years		After 5 Years		Total
	(in thousands)
Debt (1)	$	3,504	$	—	$	—	$	—	$	3,504
Operating leases		213		2,563		1,732		1,272		5,780
Payments to EPA(2)		2,208		4,365		2,158		—		8,731
	$	5,925	$	6,928	$	3,890	$	1,272	$	18,015

(1) Includes interest payments through maturity of $4,000. Interest payments on debt are based on interest rates as of September 30, 2013.

(2) In accordance with the Consent Decree, the Company has agreed to pay a fixed sum for the EPA’s past cost for OU-2 and a portion of the EPA’s past cost for OU-1. The payments are to be made in five equal payments of $2,141,000, for a total $10,705,000, plus interest. On May 10, 2013, the Company made the first payment related to its obligation under the Consent Decree in the amount of $2,185,000, which included interest. The next four payments will be made on the anniversary of the first payment plus ten days in the same amount of $2,141,000, plus interest (See Note 13 – Commitments and Contingencies for the terms and conditions of the Consent Decree).

The table above excludes the Company’s gross liability for uncertain tax positions of $819,000, including accrued interest and penalties, which totaled $97,000 as of September 30, 2013, since the Company cannot predict with reasonable reliability the timing or certainty of cash settlements to the respective taxing authorities.

Off-Balance Sheet Arrangements

It is not the Company’s usual business practice to enter into off-balance sheet arrangements such as guarantees on loans and financial commitments, indemnification arrangements and retained interests in assets transferred to an unconsolidated entity for securitization purposes. Consequently, the Company has no off-balance sheet arrangements which have, or are reasonably likely to have, a material current or future effect on its financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources, except for operating lease commitments disclosed in the table above and inventory purchase commitments.

In an attempt to stabilize copper costs, the Company has in the past, and may in the future, enter into purchase agreements for copper. As of September 30, 2013, inventory purchase agreements for copper totaled $2,302,000. As of September 30, 2013, no purchase commitments for copper were greater than twelve months.

In 2013, the Company’s income from operations increased by $1,172,000 from $3,533,000 in 2012 to $4,705,000 in 2013. Income from operations was 9% of net sales in 2013, compared to 7% of net sales in 2012. All of the Company’s operating entities recorded income from operations in 2013 and 2012. In addition, Unallocated Corporate Expenses increased by $366,000, or 32%, in 2013 compared to 2012.

42

Income from continuing operations in 2013 was $3,434,000, or $0.82 per diluted share, compared to income from continuing operations in 2012 of $2,865,000, or $0.69 per diluted share. Income from continuing operations was approximately 6% of net sales in 2013, compared to income from continuing operations of 6% of net sales in 2012.

The Company’s business segments and the components of operating expenses are discussed in the following sections.

SLPE

SLPE recorded net sales of $22,370,000 or 42% of consolidated net sales in 2013, compared to $21,194,000, or 42% of consolidated net sales in 2012. At SLPE, sales of the data communications product line increased by $699,000, or 30%, sales of the industrial product line increased by $668,000, or 20%, and sales of the medical equipment product line increased by $128,000, or 1%, which were partially offset by a decrease in sales of other products of $319,000, or 38%. The increase in sales in the data communications product line was primarily due to increased domestic distributor sales. The increase in sales in the industrial product line was primarily due to increased domestic distributor sales, which was partially offset by decreased sales to a large international customer. The increase in sales of the medical equipment product line was primarily due to increased sales volumes to several large international and domestic customers, which was partially offset by a decrease in domestic distributor sales. The decrease in sales of other products was primarily due to a decrease in volumes as a result of a shift in focus to standard platform products and services. Returns and distributor credits also negatively affected net sales, which represented approximately 1% and 2% of SLPE gross sales in 2013 and 2012, respectively. Domestic sales increased by 2% and international sales increased by 17% during 2013.

SLPE reported income from operations of $2,115,000 in 2013, compared to $1,144,000 in 2012. Income from operations increased in 2013 primarily due to an improvement in cost of products sold as a percentage of net sales and a decrease in operating costs. Cost of products sold as a percentage of net sales improved approximately 2% during 2013. Operating costs decreased by approximately $261,000, or 6%, during 2013 primarily due to $727,000 of restructuring charges in 2012 and a decrease in depreciation and amortization expense of $48,000, which were partially offset by an increase in selling, general and administrative expenses of $456,000, or 18%, and an increase in engineering and product development costs of $58,000, or 5%.

High Power Group

The High Power Group reported net sales of $16,396,000, or 31% of consolidated net sales in 2013, compared to $15,620,000, or 31% of consolidated net sales in 2012. The increase in net sales during 2013 was due to an increase in net sales at MTE of $396,000, or 5% and an increase in net sales at TEAL of $380,000, or 5%.

MTE’s sales increase during 2013 was primarily attributable to an increase in reactor sales to the industrial automation industry and filter sales to the oil industry. Domestic sales increased by 13% while international sales decreased by 18%. The increase in domestic sales was primarily due to increased reactor sales to a large industrial automation OEM and increased filter sales to several large domestic customers in the oil industry and the introduction of new matrix filter products. The decrease in international sales was primarily due to decreased sales to a large customer and a large distributor in the oil industry located in South America.

43

TEAL’s sales increase was primarily attributable to an increase in sales to the semi-conductor market of $1,386,000, an increase in sales to customers in the solar market of $425,000, and an increase in sales to the military and aerospace markets of $385,000, which were partially offset by a decrease in sales to the medical imaging equipment market of $1,796,000. The increase in the semi-conductor market was primarily driven by sales of new products to two large international customers. Sales to customers in the solar market increased during 2013 primarily due to increased sales to a new large domestic customer, partially offset by decreased sales to a large domestic customer. Sales to military and aerospace customers increased during 2013 primarily due to increased volumes to a domestic customer, partially offset by decreased sales to a large international customer. The decrease in sales to the medical imaging equipment market was primarily due to a general decline in demand in this market as evidenced by a decrease in sales to several large domestic and international customers. Domestic sales decreased by 12%, and international sales increased by 259% during 2013.

The High Power Group reported income from operations of $1,444,000 in 2013, which represented a decrease of 4% from 2012. The decrease in income from operations during 2013 was due to a decrease at TEAL of $344,000, which was partially offset by an increase at MTE of $289,000. The decrease in the High Power Group’s income from operations was due to an increase in cost of products sold as a percentage of sales, which was partially offset by a 5% increase in sales and a 5% decrease in operating costs. Cost of products sold as a percentage of net sales increased by approximately 3% during 2013. Operating costs decreased by $152,000 primarily due to a decrease in selling, general and administrative expenses of $99,000 and a decrease in depreciation and amortization expenses of $55,000, which were partially offset by an increase in engineering and product development costs of $60,000. Operating costs also decreased due to $58,000 of restructuring charges incurred during 2012 at TEAL.

SL-MTI

SL-MTI recorded net sales of $9,414,000, or 18% of consolidated net sales in 2013, compared to $9,490,000, or 18% of consolidated net sales in 2012. Sales to customers in the commercial aerospace industry decreased $352,000, or 10%, and sales to the defense industry decreased $139,000, or 3%, which were partially offset by an increase in sales of other commercial products of $250,000, or 27%, and an increase in sales of medical products of $165,000, or 76%. Domestic sales were relatively flat during 2013 primarily due to an increase in the industrial product line due to a new domestic customer project, which was partially offset by a decrease in sales volumes to several commercial aerospace customers. International sales decreased by 8% during 2013 primarily due to decreased volumes to military customers located in Canada and the United Kingdom.

SL-MTI reported income from operations of $1,880,000 in 2013, which represented an increase of less than 1% from 2012. Income from operations was relatively flat in 2013 primarily due a decrease in operating costs, which was partially offset by a 1% decrease in sales. Operating costs decreased by 2% due to a decrease in engineering and product development costs of $72,000, which was partially offset by an increase in selling, general and administrative expenses of $31,000. Cost of products sold as a percentage of net sales was relatively flat during 2013.

44

RFL

RFL recorded net sales of $4,819,000, or 9% of consolidated net sales in 2013, compared to $4,582,000, or 9% of consolidated net sales in 2012. Sales of RFL’s communication products increased by $191,000, or 9%, and sales of protection products increased by $68,000, or 3%, which were partially offset by a decrease in customer service sales of $22,000, or 12%. The increase in the communications product line during 2013 was primarily due a new large domestic customer project in 2013 without a comparable project in 2012. The increase in protection products was primarily due to an increase in legacy product sales, partially offset by decreased sales volumes to a customer in Mexico. Customer service sales, which are a relatively minor component of RFL’s sales, decreased primarily due to reduced spare parts sales to a domestic customer. Domestic sales increased by $775,000, or 23%, while international sales decreased by $538,000, or 44%.

RFL reported income from operations of $770,000 in 2013, which represented an increase of 403% from 2012. Income from operations increased in 2013 due primarily to a 5% increase in sales, a 7% decrease in cost of products sold as a percentage of net sales, and a 9% decrease in operating costs. Operating costs decreased by 9% primarily due to a $78,000 decrease in selling, general, and administrative expenses and a $41,000 decrease in engineering and product development expenses, which were partially offset by a $12,000 increase in depreciation and amortization expenses. Operating costs also decreased due to $67,000 of restructuring charges incurred during 2012.

Cost of Products Sold

Cost of products sold was approximately 67% of net sales in 2013, compared to 68% for the quarter ended 2012. Cost of products sold as a percentage of net sales decreased 1% while net sales increased 4% during 2013.

SLPE and RFL each recorded an improvement in cost of products sold as a percentage of net sales, while the High Power Group recorded an increase in cost of products sold as a percentage of net sales. Cost of products sold at SL-MTI was relatively flat during 2013. SLPE’s cost of products sold as a percentage of net sales decreased by approximately 2% during 2013 primarily due to a favorable product mix partially due to the introduction of new products into the market, and a decrease in the inventory reserve during 2013. The decrease in SLPE’s cost of products sold as a percentage of net sales was also due to the recording of additional social taxes in China during 2012. The High Power Group recorded a 3% increase in its cost of products sold as a percentage of net sales due to a 7% increase at TEAL, which was partially offset by a 1% decrease at MTE. The increase in cost of products sold as a percentage of net sales at TEAL was primarily due to an unfavorable sales mix, an increase in inventory reserve, and an increase in freight and delivery expenses. The decrease in cost of products sold as a percentage of net sales at MTE was primarily due to an improved product mix, a decrease in raw materials costs, and increased sales levels which improved overhead absorption. The decrease at MTE was also due to a shift in labor to Mexico. Cost of products sold as a percentage of net sales decreased by 7% at RFL primarily due to a favorable market mix and favorable project mix. All operating entities are at various stages of emphasizing lean initiatives throughout the factory floor to reduce costs of products sold.

45

Engineering and Product Development Expenses

Engineering and product development expenses were approximately 6% of net sales in 2013 and 2012. Engineering and product development expenses increased by $5,000, or less than 1% during the third quarter of 2013 primarily due to an increase of $60,000 at the High Power Group, and an increase of $58,000 at SLPE, which were partially offset by a decrease of $72,000 at SL-MTI and a decrease of $41,000 at RFL. The increase in engineering and product development costs at the High Power Group was primarily due to an increase in engineering staff and employee compensation costs at MTE, which was partially offset by decreased new product development costs at TEAL. The increase in engineering and product development costs at SLPE was primarily due to an increase in other compensation costs, partially offset by a decrease in consulting fees. The decrease in engineering and product development costs at SL-MTI was primarily due to a decrease in prototype development costs. Engineering and product development costs at RFL decreased primarily due to a decrease in salaries and other compensation costs due to a lower employee headcount.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were approximately 17% of net sales for 2013, compared to 16% in 2012. During 2013, selling, general and administrative expenses increased by $676,000, or 8%, while sales increased by 4%. Selling, general and administrative expenses at SLPE increased by $456,000 in 2013 primarily due to increased salaries and other compensation costs and increased advertising expenses, which were partially offset by a decrease in consulting fees related to costs incurred in 2012 in connection with China Investigation. Selling, general and administrative expenses at SL-MTI increased by $31,000 primarily due to an increase in compensation costs and an increase in rent expense for a new satellite office in 2013. The High Power Group recorded a decrease in selling, general and administrative expenses of $99,000 due to decreases at MTE and TEAL. The decrease at MTE was primarily due to a decrease in litigation costs which were incurred in 2012, which was partially offset by increased salaries due to an increase in headcount and increased commissions related to higher sales volumes. The decrease at TEAL was primarily due to lower compensation costs. Selling, general and administrative expenses at RFL decreased by $78,000 primarily due to an insurance settlement received related to damages incurred from Hurricane Sandy, which was partially offset by an increase in consulting fees. Unallocated Corporate Expenses increased by $366,000 primarily due to increased employee compensation costs resulting from a reversal of bonus accruals in 2012, and Delaware state franchise tax incurred in 2013 resulting from the Company’s reincorporation in Delaware.

Depreciation And Amortization Expenses

Depreciation and amortization expenses in 2013 were $578,000, a decrease of $88,000, or 13%, compared to depreciation and amortization expenses in 2012.

Amortization of Deferred Financing Costs

In connection with entering into the 2012 Credit Facility and related amendments, the Company incurred deferred financing costs which are amortized over the term of the 2012 Credit Facility. Costs related to the 2008 Credit Facility and related waivers and amendments, which expired on August 9, 2012, were amortized over the term of the 2008 Credit Facility. During 2013 and 2012, the amortization of deferred financing costs equaled $21,000 and $46,000, respectively.

46

Interest Expense

Interest expense in 2013 was $21,000 compared to $8,000 in 2012. The increase in interest expense in 2013 was primarily due to increased borrowings under the Company’s 2012 Credit Facility during 2013 compared to borrowings during the same period in 2012. The Company had an outstanding balance of $3,500,000 as of September 30, 2013 and no outstanding balance as of September 30, 2012.

Other gain (loss), net

Other gain (loss), net in 2013 was a net loss of $21,000 compared to net gain of $312,000 in 2012. During 2012 and 2013, the Company entered into a series of foreign currency forward contracts to hedge its exposure to foreign exchange rate movements in its forecasted expenses in China and Mexico. The loss recognized in 2013 and the gain recognized in 2012 represents the change in fair value of foreign currency forward contracts that are marked to market at quarter end.

Taxes (Continuing Operations)

The effective tax rate from continuing operations during 2013 was approximately 26% as compared to 24% during 2012. The increase in the effective tax rate was due to a decrease in foreign tax credits and international rate differences, which were partially offset by certain permanent adjustments.

Discontinued Operations

During 2013, the Company recorded a loss from discontinued operations, net of tax, of $282,000, compared to a loss of $464,000, net of tax, in 2012. The loss from discontinued operations during 2013 and 2012 relates to environmental remediation costs, consulting fees, and legal expenses associated with the past operations of the Company’s five environmental sites (See Note 13 – Commitments and Contingencies for further information concerning the environmental sites).

Net Income

Net income was $3,152,000, or $0.75 per diluted share, for 2013 compared to $2,401,000, or $0.58 per diluted share, for 2012. The weighted average number of shares used in the diluted earnings per share computation was 4,184,000 and 4,133,000 for 2013 and 2012, respectively.

The Company’s business segments and the components of operating expenses are discussed in the following sections.

SLPE

SLPE recorded net sales of $58,350,000 or 38% of consolidated net sales in 2013, compared to $58,361,000, or 39% of consolidated net sales in 2012. At SLPE, sales of the industrial product line decreased by $743,000, or 8%, and sales of other products decreased by $588,000, or 30%, which were partially offset by an increase in sales of the medical equipment product line of $691,000, or 2%, and an increase in sales of the data communications product line of $629,000, or 9%. The decrease in sales in the industrial product line was primarily due to a general decline in demand in this market as evidenced by a decrease in domestic distributor sales. The decrease was also due to a decrease in sales volumes to a large international customer during 2013. The decrease in sales of other products was primarily due to a decrease in volumes as a result of a shift in focus to standard platform products and services. The increase in sales of the medical equipment product line was primarily due to increased sales volumes to several large domestic and international customers, which was partially offset by a decrease in domestic distributor sales. The increase in sales of the data communications product line was primarily due to increased domestic distributor sales. Returns and distributor credits also negatively affected net sales, which represented approximately 1% and 2% of SLPE gross sales in 2013 and 2012, respectively. Domestic sales decreased by 3% and international sales increased by 8% during 2013.

SLPE reported income from operations of $4,296,000 in 2013, compared to $1,412,000 in 2012. Income from operations increased in 2013 primarily due to an improvement in cost of products sold as a percentage of net sales and a decrease in operating costs. Cost of products sold as a percentage of net sales improved by 3% as a percentage of net sales during 2013. Operating costs decreased by approximately $1,325,000, or 9%, during 2013, primarily due to a decrease in selling, general and administrative expenses of $514,000, and a decrease in depreciation and amortization expense of $168,000, which were partially offset by an increase in engineering and product development costs of $84,000. Operating costs also decreased due to $727,000 of restructuring charges incurred during 2012.

Included in cost of products sold and operating costs during 2013 are $662,000 ($555,000 recorded in cost of products sold and $107,000 recorded in selling, general and administrative expenses) of incremental costs related to a work stoppage in China. Also, SLPE incurred $836,000 in legal and accounting fees related to the FCPA investigation in China in 2012 that were not repeated in 2013.

High Power Group

The High Power Group reported net sales of $51,096,000, or 34% of consolidated net sales in 2013, compared to $47,091,000, or 32% of consolidated net sales in 2012. The increase in net sales during 2013 was due to an increase in net sales at MTE of $4,501,000, or 19%, which was partially offset by a decrease at TEAL of $496,000, or 2%.

49

MTE’s sales increase during 2013 was primarily attributable to an increase in filter sales to the oil industry and the introduction of new matrix filter products, and an increase in reactor sales to the industrial automation market. Domestic sales increased by 28% while international sales decreased by 7%. The increase in domestic sales was primarily due to increased filter sales to two large customers in the oil industry and increased reactor sales to a large industrial automation OEM. The decrease in international sales was primarily due to decreased sales to a large customer and a large distributor in the oil industry located in South America, which was partially offset by increased sales to a large customer in the mining market.

TEAL’s sales decrease was primarily attributable to a decrease in sales to the medical imaging equipment market of $2,480,000, which was partially offset by an increase in sales to the semi-conductor market of $1,256,000, an increase in sales to customers in the solar market of $532,000, and an increase in sales to the military and aerospace markets of $220,000. The decrease in sales to the medical imaging equipment market was primarily due to a general decline in demand in this market as evidenced by a decrease in sales to several domestic and international customers. The increase in the semi-conductor market was primarily driven by sales of new products to two large international customers. Sales to customers in the solar market increased during 2013 primarily due to increased sales to a new large domestic customer, partially offset by decreased sales to a large domestic customer. Sales to military and aerospace customers increased during 2013 primarily due to increased sales volumes to a large domestic customer, partially offset by decreased volumes to a large domestic customer and a large international customer. Domestic sales decreased by 9%, and international sales increased by 54% during 2013.

The High Power Group reported income from operations of $5,596,000 in 2013, which represented an increase of 26% from 2012. The increase in income from operations during 2013 was due to an increase at MTE of $2,160,000, which was partially offset by a decrease of $1,013,000 at TEAL. The increase in the High Power Group’s income from operations was due to an increase in sales of 9% and a decrease in cost of products sold as a percentage of net sales, which were partially offset by an increase in operating expenses. Cost of products sold as a percentage of net sales improved by approximately 1% during 2013. Operating costs increased by $412,000, or 4%, during 2013 primarily due to an increase in engineering and product development costs of $512,000 and an increase in selling, general and administrative expenses of $67,000, which were partially offset by a decrease in depreciation and amortization expenses of $109,000. Operating costs also decreased due to $58,000 of restructuring charges incurred during 2012 at TEAL, and the absence of legal costs which were incurred in 2012 at MTE.

SL-MTI

SL-MTI recorded net sales of $27,568,000, or 18% of consolidated net sales in 2013, compared to $28,166,000, or 19% of consolidated net sales in 2012. Sales to customers in the commercial aerospace industry decreased by $890,000, or 8%, and sales to the defense industry decreased by $593,000, or 4%, which were partially offset by an increase in sales of other commercial products of $759,000, or 39%, and an increase in sales of medical products of $126,000, or 17%. Domestic sales decreased by 1% and international sales decreased by 14% during 2013. The decrease in domestic sales was primarily due to decreased sales volumes to several customers in the commercial aerospace industry, which was partially offset by increased downhole exploration sales in the oil and gas market and a new customer project in the industrial market. The decrease in domestic sales was also partially offset by $582,000 of non-comparable Astromec sales in 2013. The decrease in international sales was primarily related to decreased military sales to customers located in Australia and the United Kingdom.

SL-MTI reported income from operations of $4,762,000 in 2013, which represented a decrease of 5% from 2012. The decrease was primarily due to a 2% decrease in sales and an increase in operating costs, which was partially offset by a 1% improvement in cost of products sold as a percentage of net sales. Operating costs increased by 6% primarily due to an increase of $574,000 in engineering and product development costs and an increase of $63,000 in depreciation and amortization expenses, which were partially offset by a decrease in selling, general and administrative expenses of $351,000. SL-MTI recorded $432,000 of direct costs related to the Astromec acquisition during 2012.

RFL

RFL recorded net sales of $14,866,000, or 10% of consolidated net sales in 2013, compared to $15,507,000, or 10% of consolidated net sales in 2012. Sales of RFL’s protection products decreased by $412,000, or 5%, customer service sales decreased by $205,000, or 25%, and sales of communications products decreased by $24,000, or less than 1%. The decrease in protection products was primarily due to a large domestic project in 2012 without a project of comparable size in 2013. Customer service sales, which are a relatively minor component of RFL’s sales, decreased primarily due to reduced spare parts sales to a domestic customer. The decrease in the communications product line during 2013 was primarily due to decreased sales to a large domestic customer in the railroad industry, which were partially offset by increased sales related to a large new domestic project in 2013. Domestic sales increased by $163,000, or 1%, and international sales decreased by $804,000, or 27%.

RFL reported income from operations of $2,099,000 in 2013, which represented an increase of 17% from 2012. Income from operations increased in 2013 due primarily to an improvement in cost of products sold as a percentage of net sales and a decrease in operating costs, which were partially offset by a 4% decrease in sales. Cost of products sold as a percentage of net sales improved by 2% during 2013. Operating costs decreased by 6% primarily due to a $274,000 decrease in selling, general and administrative expenses and a $32,000 decrease in depreciation and amortization expenses, which were partially offset by an increase of $35,000 in engineering and product development expenses. Operating costs also decreased due to $67,000 of restructuring charges incurred during 2012. Included in selling, general and administrative expenses is a business insurance settlement of $205,000, which was received in September 2013.

51

Cost of Products Sold

Cost of products sold was approximately 66% of net sales in 2013, compared to 68% in 2012. Cost of products sold as a percentage of net sales decreased 2% while net sales increased by 2% during 2013.

All of the Company’s operating entities recorded an improvement in cost of products sold as a percentage of net sales during 2013. SLPE’s cost of products sold as a percentage of net sales decreased by approximately 3% during 2013 primarily due to a favorable sales mix, a favorable product mix partially due to the introduction of new products into the market, a decrease in labor costs associated with the implementation of a prior year restructuring plan, and a decrease in inventory reserve during 2013 compared to 2012. SLPE’s cost of products sold as a percentage of net sales also decreased due to the recording of additional social taxes in China in 2012. The decrease in SLPE’s cost of products sold as a percentage of net sales was partially offset by $555,000 of additional costs incurred due to a work stoppage in China during March 2013. The High Power Group recorded a 1% decrease in its cost of products sold as a percentage of net sales due to a 3% decrease at MTE, which was partially offset by a 3% increase at TEAL. The decrease in cost of products sold as a percentage of net sales at MTE was primarily due to improved product mix and a decrease in commodity costs, primarily for copper and steel. The decrease at MTE was also due to a shift in labor to Mexico and increased sales levels, which improved overhead absorption. The improvements in cost of products sold as a percentage of net sales at MTE were partially offset by an increase in the inventory reserve during 2013. The increase in cost of products sold as a percentage of net sales at TEAL was primarily due to an unfavorable sales mix, an increase in the inventory reserve, and higher labor costs due to additional support needed for new product programs. The increase in cost of products sold as a percentage of net sales at TEAL was partially offset by lower commodity costs, primarily for copper and steel. During 2013, SL-MTI recorded a 1% decrease in its cost of products sold as a percentage of net sales primarily due to a more favorable sales mix and lower commodity costs. The decrease at SL-MTI was also due to increased costs incurred during the first nine months of 2012 due to Astromec integration costs. RFL recorded a 2% decrease in its cost of products sold as a percentage of net sales due to a favorable market mix and project mix, partially offset by unfavorable overhead variances due to a decrease in sales volumes. All operating entities are at various stages of emphasizing lean initiatives throughout the factory floor to reduce costs of products sold.

Engineering and Product Development Expenses

Engineering and product development expenses were approximately 7% of net sales in 2013 compared to 6% in 2012. Engineering and product development expenses increased by $1,205,000, or 13%, during 2013 primarily due to an increase of $574,000 at SL-MTI, an increase of $512,000 at the High Power Group, increase at SLPE of $84,000, and an increase of $35,000 at RFL. The increase in engineering and product development costs at SL-MTI was primarily due to a decrease in customer funding received for prototype projects during 2013 coupled with an increase in prototype development costs. The increase in engineering and product development costs at the High Power Group was primarily due to increased new product development costs at TEAL and an increase in engineering staff and employee compensation costs at MTE. The increase in engineering and product development costs at SLPE was primarily due to an increase in other compensation costs during 2013. Engineering and product development costs at RFL increased primarily due to an increase in new product development costs primarily in the communications product line, which was partially offset by lower employee compensation costs due to a lower employee headcount.

52

Selling, General and Administrative Expenses

Selling, general and administrative expenses were approximately 18% of net sales for 2013, compared to 19% in 2012. During 2013, selling, general and administrative expenses decreased by $1,061,000, or 4%, while sales increased by 2%. Selling, general and administrative expenses at SLPE decreased by $514,000 in 2013 primarily due to costs incurred for consulting and legal fees in 2012 in connection with the China Investigation, which were partially offset by an increase in other compensation costs during 2013 and $107,000 of additional costs incurred due to a work stoppage in China during March 2013. Selling, general and administrative expenses at SL-MTI decreased by $351,000 primarily due to direct acquisition costs incurred in 2012 related to the Astromec acquisition. Selling, general and administrative expenses at RFL decreased by $274,000 primarily due a business insurance settlement received related to damages incurred from Hurricane Sandy, as mentioned previously, and lower compensation costs, which was partially offset by an increase in consulting fees. The High Power Group recorded an increase in selling, general and administrative expenses of $67,000 primarily due to an increase in salaries related to an increase in employee headcount, and increased other employee compensation costs related to commissions on higher sales volumes at MTE. The increase at the High Power Group was partially offset by a decrease in compensation costs at TEAL and the absence of litigation costs at MTE in 2012. Unallocated Corporate Expenses were relatively flat during 2013.

Depreciation And Amortization Expenses

Depreciation and amortization expenses in 2013 were $1,793,000, a decrease of $245,000, or 12%, compared to depreciation and amortization expenses in 2012.

Amortization of Deferred Financing Costs

In connection with entering into the 2012 Credit Facility and related amendments, the Company incurred deferred financing costs which are amortized over the term of the 2012 Credit Facility. Costs related to the 2008 Credit Facility and related waivers and amendments, which expired on August 9, 2012, were amortized over the term of the 2008 Credit Facility. During 2013 and 2012, the amortization of deferred financing costs equaled $60,000 and $118,000, respectively.

Interest Expense

Interest expense in 2013 was $71,000 compared to $39,000 in 2012. The increase in interest expense in 2013 was primarily due to increased borrowings during 2013 compared to borrowings during the same period in 2012. The Company had an outstanding balance of $3,500,000 as of September 30, 2013 and no outstanding balance as of September 30, 2012.

Other gain (loss), net

Other gain (loss), net in 2013 was a net loss of $348,000 compared to net gain of $142,000 in 2012. During 2012 and 2013, the Company entered into a series of foreign currency forward contracts to hedge its exposure to foreign exchange rate movements in its forecasted expenses in China and Mexico. The loss recognized in 2013 and the gain recognized in 2012 represents the change in fair value of foreign currency forward contracts that are marked to market.

53

Taxes (Continuing Operations)

The effective tax rate from continuing operations during 2013 was approximately 27% as compared to 31% during 2012. The decrease in the effective tax rate was primarily due to the recording of a research and development tax benefit of $906,000 in 2013, of which $431,000 was related to the retroactive reinstatement of the federal research and development tax credits from the enactment of the American Tax Relief Act of 2012. These credits were not available to the Company in 2012.

Discontinued Operations

During 2013, the Company recorded a loss from discontinued operations, net of tax, of $737,000, compared to a loss of $902,000, net of tax, in 2012. The loss from discontinued operations during 2013 and 2012 relates to environmental remediation costs, consulting fees, and legal expenses associated with the past operations of the Company’s five environmental sites (See Note 13 – Commitments and Contingencies for further information concerning the environmental sites).

Net Income

Net income was $7,933,000 or $1.89 per diluted share, for 2013 compared to $4,817,000, or $1.10 per diluted share, for 2012. The weighted average number of shares used in the diluted earnings per share computation was 4,190,000 and 4,390,000 for 2013 and 2012, respectively.

Not applicable.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of the Company’s “disclosure controls and procedures,” as such term is defined in Rules 13a-15e and 15d-15e promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Conclusion of Evaluation

Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Inherent Limitations on Effectiveness of Controls and Procedures

In designing and evaluating the Company’s disclosure controls and procedures, management recognizes that any control, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the third quarter of 2013 that have materially affected or are reasonably likely to materially affect its internal control over financial reporting.

Earnings Per Share [Abstract]

Income Per Share

4. Income Per Share

The Company has presented net income per common share pursuant to Accounting Standards Codification (“ASC”) 260 “Earnings Per Share.” Basic net income per common share is computed by dividing reported net income available to common shareholders by the weighted average number of shares outstanding for the period.

Diluted net income per common share is computed by dividing reported net income available to common shareholders by the weighted average shares outstanding for the period, adjusted for the dilutive effect of common stock equivalents, which consist of stock options, using the treasury stock method.

The table below sets forth the computation of basic and diluted net income per share:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2013			2012			2013			2012
	(in thousands, except per share amounts)
Basic net income available to common shareholders:
Net income available to common shareholders from continuing operations	$	3,434		$	2,865		$	8,670		$	5,719
Diluted net income available to common shareholders from continuing operations	$	3,434		$	2,865		$	8,670		$	5,719
Shares:
Basic weighted average number of common shares outstanding		4,134			4,121			4,144			4,375
Common shares assumed upon exercise of stock options		50			12			46			15
Diluted weighted average number of common shares outstanding		4,184			4,133			4,190			4,390
Basic net income (loss) per common share:
Income from continuing operations	$	0.83		$	0.69		$	2.09		$	1.31
(Loss) from discontinued operations (net of tax)		(0.07	)		(0.11	)		(0.18	)		(0.21	)
Net income	$	0.76		$	0.58		$	1.91		$	1.10
Diluted net income (loss) per common share:
Income from continuing operations	$	0.82		$	0.69		$	2.07		$	1.30
(Loss) from discontinued operations (net of tax)		(0.07	)		(0.11	)		(0.18	)		(0.20	)
Net income	$	0.75		$	0.58		$	1.89		$	1.10

For the three and nine months ended September 30, 2013, no stock options were excluded from the dilutive computation because the option exercise prices were not greater than the average market price of the Company’s common stock.

For the three and nine months ended September 30, 2012, 9,000 and 6,000 stock options were excluded from the dilutive computation, respectively, because the option exercise prices were greater than the average market price of the Company’s common stock.

Derivative Instruments and Hedging Activities

18. Derivative Instruments and Hedging Activities

ASC Topic 815, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC Topic 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows related to forecasted foreign exchange-based risk are considered economic hedges of the Company’s forecasted cash flows.

Risk Management Objective of Using Derivatives

The Company is a U.S. dollars (USD) functional currency entity that manufactures products in the USA, Mexico and China. The Company’s sales are priced in USD and its costs and expenses are priced in USD, Mexican pesos (MXN) and Chinese Yuan (CNH). As a result, the Company has exposure to changes in exchange rates between the time when expenses in the non-functional currencies are initially incurred and the time when the expenses are ultimately paid. The Company’s objective in using derivatives is to add stability and to manage its exposure to foreign exchange risks. To accomplish this objective, the Company uses foreign currency forward contracts to manage its exposure to fluctuations in the exchange rates. Foreign currency forward contracts involve fixing the USD-MXN and USD-CNH exchange rates for delivery of a specified amount of foreign currency on a specified date.

During 2012 and 2013, the Company entered into a series of foreign currency forward contracts to hedge its exposure to foreign exchange rate movements in its forecasted expenses in China and Mexico. The foreign currency forwards are not speculative and are being used to manage the Company’s exposure to foreign exchange rate movements. Foreign currency forward contracts involve fixing the USD-MXN and USD-CNH exchange rates for delivery of a specified amount of foreign currency on a specified date. The Company has elected not to apply hedge accounting to these derivatives and they are marked to market through earnings. Therefore, gains and losses resulting from changes in the fair value of these contracts are recognized at the end of each reporting period directly in earnings. The gains and losses associated with the foreign currency forward contracts are included in other gain (loss), net on the Consolidated Statements of Income. As of September 30, 2013, the fair value of the foreign currency forward contracts was recorded as a $105,000 liability in other current liabilities on the Consolidated Balance Sheets. As of December 31, 2012, the fair value of the foreign currency forward contracts was recorded as a $243,000 asset in other current assets on the Consolidated Balance Sheets.

Non-designated Hedges of Foreign Exchange Risk

The notional amounts are used to measure the volume of foreign currency forward contracts and do not represent exposure to foreign currency losses. The following table summarizes the notional values of the Company’s derivative financial instruments as of September 30, 2013.

Product	Number of Instruments		Notional
			(in thousands)
Mexican Peso (MXN) Forward Contracts		18	MXN	72,392

Stock-Based Compensation

5. Stock-Based Compensation

At September 30, 2013, total compensation expense (included in selling, general and administrative expense) related to stock-based compensation plans for the three and nine months ended September 30, 2013 was $114,000 and $446,000 ($85,000 and $326,000 net of tax), respectively. For the three and nine months ended September 30, 2012, total compensation expense was $165,000 and $909,000 ($154,000 and $631,000, net of tax), respectively.

During the first quarter of 2013, the Company implemented a Long-Term Incentive Plan (the “2013 LTIP”) pursuant to the 2008 Incentive Stock Plan (the “2008 Plan”) which awarded restricted stock units (“RSUs”) to eligible executives. Under the terms of the 2013 LTIP, the number of RSUs that may vest, if any, will be based on, among other things, the Company achieving certain sales and return on invested capital (“ROIC”), as defined, targets during the January 2013 to December 2015 performance period. Earned RSUs, if any, cliff vest at the end of fiscal 2015 (100% of earned RSUs vest at December 31, 2015). The final value of these RSUs will be determined by the number of shares earned. The value of these RSUs is charged to compensation expense on a straight-line basis over the three year vesting period with periodic adjustments to account for changes in anticipated award amounts. The weighted-average price for these RSUs was $19.17 per share based on the grant date of March 5, 2013. During the three and nine months ended September 30, 2013, $31,000 and $74,000 was charged to compensation expense, respectively. As of September 30, 2013, total unamortized compensation expense for this grant was $292,000. As of September 30, 2013, the maximum number of achievable RSUs under the 2013 LTIP was 28,000 RSUs.

On May 9, 2013, the Company granted each Director 3,000 restricted shares pursuant to the 2008 Plan. The shares vest upon the first anniversary of the grant date. Based on the terms of the awards the value of these restricted shares is charged to compensation expense on a straight-line basis over the one year vesting period. As a result, the Company recognized $77,000 and $122,000 of stock compensation expense during the three and nine months ended September 30, 2013, respectively. As of September 30, 2013, total unamortized compensation expense for this grant was $187,000. The weighted-average price of these restricted stock grants was $20.60 per share based on the grant date of May 9, 2013. As of September 30, 2013, no shares were granted under this award.

Stock Options

Option activity under the principal option plans as of September 30, 2013 and changes during the nine months ended September 30, 2013 were as follows:

	Outstanding Options			Weighted Average Exercise Price		Weighted Average Remaining Life		Aggregate Intrinsic Value
	(in thousands)					(in years)		(in thousands)
Outstanding as of December 31, 2012		135		$	12.79		4.33	$	670
Granted		—			—
Exercised		(46	)		13.64
Forfeited		—			—
Expired		—			—
Outstanding as of September 30, 2013		89		$	12.35		3.58	$	1,129
Exercisable as of September 30, 2013		83		$	11.99		3.54	$	1,074

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the third quarter of fiscal 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2013. This amount changes based on the fair market value of the Company’s stock. The total intrinsic value of options exercised for the nine months ended September 30, 2013 was $563,000. No options were exercised during the nine months ended September 30, 2012.

As of September 30, 2013, $10,000 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 0.2 years.

Tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options are classified as financing cash flows. Cash received from option exercises for the nine months ended September 30, 2013 was $631,000. The actual tax benefit realized for the tax deduction from option exercises of share-based payment arrangements totaled $203,000 for the nine months ended September 30, 2013. No options were exercised during the nine months ended September 30, 2012. The Company has applied the “Short-cut” method in calculating the historical windfall tax benefits. All tax shortfalls will be applied against this windfall before being charged to earnings.

Earnings Per Share [Abstract]

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation. Operating results for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. These financial statements should be read in conjunction with the Company’s audited financial statements and notes thereon included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Unless the context requires otherwise, the terms the “Company,” “SL Industries,” “we,” “us” and “our” mean SL Industries, Inc., a Delaware corporation, and its consolidated subsidiaries after Reincorporation (defined and described below) and SL Industries, Inc., a New Jersey corporation prior to Reincorporation. In the context of describing the Reincorporation, “SL-NJ” means SL Industries, Inc., a New Jersey corporation, and “SL-DE” means SL Industries, Inc., a Delaware corporation and wholly owned subsidiary of SL-NJ.

On May 9, 2013, the Company’s shareholders voted to approve a proposal to change the state of incorporation of SL Industries from the State of New Jersey to the State of Delaware by merging SL-NJ with and into SL-DE (the “Reincorporation”). On June 20, 2013 (the “Effective Date”), the Reincorporation was effected by merging SL-NJ with and into SL-DE pursuant to an Agreement and Plan of Merger, dated June 3, 2012, between SL-NJ and SL-DE. SL-DE survived the merger and SL-NJ ceased to exist. The principal reason for the Reincorporation was to give the Company a greater measure of flexibility and simplicity in corporate governance and provide greater clarity and predictability with respect to the Company’s corporate legal affairs. The Reincorporation did not result in any change in the name, business, management, fiscal year, accounting, location of the principal executive officers, assets or liabilities or net worth (other than the costs of reincorporation which were immaterial) of the Company.

Income Per Share

The Company has presented net income per common share pursuant to Accounting Standards Codification (“ASC”) 260 “Earnings Per Share.” Basic net income per common share is computed by dividing reported net income available to common shareholders by the weighted average number of shares outstanding for the period.

Income Taxes - Interim Reporting

The Company calculates its interim tax provision in accordance with the provisions of ASC 740-270 “Income Taxes – Interim Reporting.” For each interim period the Company estimates its annual effective income tax rate and applies the estimated rate to its year-to-date income or loss before income taxes. The Company also computes the tax provision or benefit related to items separately reported, such as discontinued operations, and recognizes the items net of their related tax effect in the interim periods in which they occur. The Company also recognizes the effect of changes in enacted tax laws or rates in the interim periods in which the changes occur.

Recently Adopted and Issued Accounting Pronouncements

In July 2012, the FASB issued ASU 2012-02 “Intangibles-Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment,” which amends the guidance on impairment testing for indefinite-lived intangible assets. The amended guidance will allow companies to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. A company no longer will be required to test the fair value of an intangible asset unless the company determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. ASU 2012-02 is effective for interim and annual periods beginning after September 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In October 1, 2012, the FASB issued ASU 2012-04 “Technical Corrections and Improvements,” which makes certain technical corrections and improvements and conforming amendments related to fair value measurements. The amendments represent changes to clarify, correct unintended application of, or make minor improvements to the FASB Accounting Standards Codification that are not expected to have a significant effect on current accounting practice. ASU 2012-04 is effective for fiscal periods beginning after December 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-02, “Comprehensive Income (Topic 220) – Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety in the same reporting period. ASU 2013-02 is effective for fiscal periods beginning after December 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matter (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity a consensus of the FASB Emerging Issues Task Force,” which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. ASU 2013-05 is effective for fiscal periods beginning after December 15, 2013. The implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force),” which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal periods beginning after December 15, 2013. The implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

Segment Information

The Company currently operates under four business segments: SL Power Electronics Corp. (“SLPE”), the High Power Group, SL-MTI and RFL Electronics Inc. (“RFL”). Teal Electronics Corp. (“TEAL”) and MTE Corporation (“MTE”) are combined into one business segment, which is reported as the High Power Group. The Company aggregates operating business subsidiaries into a single segment for financial reporting purposes if aggregation is consistent with the objectives of ASC 280 “Segment Reporting.” Business units are also combined if they have similar characteristics in each of the following areas:

• nature of products and services

• nature of production process

• type or class of customer

• methods of distribution

Fair Value Measurement and Financial Instruments

ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. FASB ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances.

ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, FASB ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Currently, the Company uses foreign currency forward contracts to hedge its foreign currency risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including spot rates and market forward points. The fair value of the foreign currency forward contracts is based on interest differentials between the currencies being traded, spot rates and market forward points.

To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees, where applicable.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

In conjunction with its implementation of updates to the fair value measurements guidance, the Company made an accounting policy election to measure derivative financial instruments subject to master netting agreements on a net basis.

Derivative Instruments and Hedging Activities

ASC Topic 815, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC Topic 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows related to forecasted foreign exchange-based risk are considered economic hedges of the Company’s forecasted cash flows.

Goodwill and Intangible Assets

8. Goodwill And Intangible Assets

Acquisition in Fiscal 2012

On February 27, 2012, the Company purchased certain assets of Pro-Dex Astromec, Inc. (“Astromec”), a subsidiary of Pro-Dex Inc. (“Pro-Dex”), for approximately $1,050,000, which includes the assumption of liabilities for an estimated earn-out of $294,000. The acquisition was paid for in cash. SL Montevideo Technology, Inc. (“SL-MTI”) recorded direct acquisition costs of approximately $10,000 and $432,000 during the three and nine months ended September 30, 2012, respectively. Direct acquisition costs were recorded within selling, general and administrative expenses in the Consolidated Statements of Income.

At December 31, 2012, the financial statements reflected the final purchase price based on estimated fair values at the date of acquisition, including $670,000 in inventories, $202,000 in equipment, and $10,000 in other current assets. The acquisition resulted in intangible assets of $168,000 while no goodwill was recognized. Intangible assets were composed of a customer list with a useful life of 5 years. The purchase price also included $294,000 in liabilities related to an estimated earn-out, which is comprised of quarterly payments based on the performance of the acquired business over the three year period immediately following the date of acquisition. The total liability for the earn-out as of September 30, 2013 and December 31, 2012 was $130,000 and $221,000, respectively. During 2013, $119,000 was paid related to the earn-out. The results from the acquisition date through September 30, 2013 are included in the SL-MTI segment.

(1) On February 27, 2012, the Company purchased certain assets of Astromec, a subsidiary of Pro-Dex. Included in the purchase price is a customer list valued at $168,000. The estimated useful life of the asset is 5 years.

(2) During 2013 and 2012, the Company’s MTE division capitalized legal fees related to a new patent application. The estimated useful life of the asset is 20 years.

In accordance with ASC 350 “Intangibles – Goodwill and Other,” goodwill and other indefinite-lived intangible assets are not amortized, but are tested for impairment. Such impairment testing is undertaken annually, or more frequently upon the occurrence of some indication that an impairment has taken place. The Company conducted an annual impairment test as of December 31, 2012.

A two-step process is utilized to determine if goodwill has been impaired. In the first step, the fair value of each reporting unit is compared to the net asset value recorded for such unit. If the fair value exceeds the net asset value, the goodwill of the reporting unit is not adjusted. However, if the recorded net asset value exceeds the fair value, the Company performs a second step to measure the amount of impairment loss, if any. In the second step, the implied fair value of the reporting unit’s goodwill is compared with the goodwill recorded for such unit. If the recorded amount of goodwill exceeds the implied fair value, an impairment loss is recognized in the amount of the excess.

For the testing conducted as of December 31, 2012, the Company concluded that no impairment charge was warranted. Going forward there can be no assurance that economic conditions or other events may not have a negative material impact on the long-term business prospects of any of the Company’s reporting units. In such case, the Company may need to record an impairment loss, as stated above. The next annual impairment test will be conducted as of December 31, 2013, unless management identifies a triggering event in the interim.

Management has not identified any triggering events, as defined by ASC 350, during 2013. Accordingly, no interim impairment test has been performed.

Estimated future amortization expense for intangible assets subject to amortization in each of the next five fiscal years is as follows:

	Amortization Expense (in thousands)
2013	$	440
2014	$	401
2015	$	59
2016	$	40
2017	$	11

Total amortization expense, excluding the amortization of deferred financing costs, consists of amortization expense related to intangible assets and software. Amortization expense related to intangible assets for the three months ended September 30, 2013 and September 30, 2012 was $110,000 and $202,000 respectively. Amortization expense related to intangible assets for the nine months ended September 30, 2013 and September 30, 2012 was $334,000 and $603,000, respectively. Amortization expense related to software for the three months ended September 30, 2013 and September 30, 2012 was $41,000 and $40,000, respectively. Amortization expense related to software for the nine months ended September 30, 2013 and September 30, 2012 was $114,000 and $119,000, respectively.

Fair Value Measurement and Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Measurement and Financial Instruments

17. Fair Value Measurement and Financial Instruments

ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. FASB ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances.

ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, FASB ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Currently, the Company uses foreign currency forward contracts to hedge its foreign currency risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including spot rates and market forward points. The fair value of the foreign currency forward contracts is based on interest differentials between the currencies being traded, spot rates and market forward points.

To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees, where applicable.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

In conjunction with its implementation of updates to the fair value measurements guidance, the Company made an accounting policy election to measure derivative financial instruments subject to master netting agreements on a net basis.

During the third quarter of 2013, the Company purchased publicly traded equity securities which are classified as available-for-sale securities. Fair values for these investments are based on closing stock prices from active markets for identical assets and therefore are classified within Level 1 of the fair value hierarchy. The fair value of available-for-sale securities is included in other current assets in the Company’s Consolidated Balance Sheets.

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis as of September 30, 2013 and December 31, 2012, aggregated by the level in the fair value hierarchy within which those measurements fall:

	Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance at September 30, 2013

The Company does not have any fair value measurements using significant unobservable inputs (Level 3) as of September 30, 2013 and December 31, 2012.

Credit Risk Contingent Features

The Company has agreements with its derivative counterparties that contain a provision where if the Company defaults or is capable of being declared in default on any of its indebtedness, then the Company could also be declared in default on its derivative obligations.

Accounting Changes And Error Corrections [Abstract]

Recently Adopted and Issued Accounting Pronouncements

7. Recently Adopted and Issued Accounting Pronouncements

In July 2012, the FASB issued ASU 2012-02 “Intangibles-Goodwill and Other: Testing Indefinite-Lived Intangible Assets for Impairment,” which amends the guidance on impairment testing for indefinite-lived intangible assets. The amended guidance will allow companies to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. A company no longer will be required to test the fair value of an intangible asset unless the company determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. ASU 2012-02 is effective for interim and annual periods beginning after September 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In October 1, 2012, the FASB issued ASU 2012-04 “Technical Corrections and Improvements,” which makes certain technical corrections and improvements and conforming amendments related to fair value measurements. The amendments represent changes to clarify, correct unintended application of, or make minor improvements to the FASB Accounting Standards Codification that are not expected to have a significant effect on current accounting practice. ASU 2012-04 is effective for fiscal periods beginning after December 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-02, “Comprehensive Income (Topic 220) – Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety in the same reporting period. ASU 2013-02 is effective for fiscal periods beginning after December 15, 2012. The implementation of this guidance did not have a material impact on the Company’s consolidated financial statements.

In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matter (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity a consensus of the FASB Emerging Issues Task Force,” which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. ASU 2013-05 is effective for fiscal periods beginning after December 15, 2013. The implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force),” which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal periods beginning after December 15, 2013. The implementation of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

The Company had no debt outstanding as of December 31, 2012.

On August 9, 2012, the Company entered into a Credit Agreement with PNC Bank, National Association, as administrative agent and lender (“PNC Bank”), and the lenders from time to time party thereto, as amended (the “2012 Credit Facility”), to replace its Amended and Restated Revolving Credit Agreement with Bank of America, N.A, as amended (the “2008 Credit Facility”). The 2012 Credit Facility provides for borrowings up to $40,000,000 and under certain conditions maximum borrowings up to $70,000,000. The 2012 Credit Facility included a $5,000,000 sublimit for letters of credit (subsequently amended on March 11, 2013, as described below) and provides for a separate $10,700,000 letter of credit which expires one year from the date of closing, with annual extensions. The 2012 Credit Facility expires on August 9, 2016.

Borrowings under the 2012 Credit Facility bear interest, at the Company’s option, at the London interbank offering rate (“LIBOR”) plus a margin rate ranging from 1.25% to 2.0%, or the higher of a Base Rate plus a margin rate ranging from 0.25% to 1.0%. The Base Rate is equal to the highest of (i) the Federal Funds Open Rate plus 0.5% and (ii) the Prime Rate and (iii) the Daily Libor Rate plus 1%. The margin rates are based on certain leverage ratios, as defined. The Company is subject to compliance with certain financial covenants set forth in the 2012 Credit Facility, including, but not limited to, indebtedness to EBITDA, as defined, minimum levels of fixed charges and limitations on capital expenditures, as defined. Availability under the 2012 Credit Facility is based upon the Company’s trailing twelve month EBITDA, as defined.

The Company’s obligations under the 2012 Credit Facility are secured by the grant of security interests in substantially all of its assets.

On March 11, 2013, the Company entered into a First Amendment (the “First Amendment”) to the 2012 Credit Facility. The First Amendment, among other things, (a) amends the Letter of Credit (“LC”) sublimit amount to the lesser of (i) an amount equal to $5,000,000 plus the aggregate amount of Designated Usage LC issued and outstanding under the Designated Usage LC sublimit or (ii) $25,000,000 and (b) allows the Company to enter into foreign currency exchange services with Loan Parties on an unsecured basis and that such obligations shall not exceed at any time an aggregate amount equal to $3,500,000. In consideration for this amendment, the Company incurred $14,000 in fees and expenses, which are amortized over the remaining life of the 2012 Credit Facility.

On May 28, 2013 a letter of credit in the amount of $8,564,000 was issued in favor of the Environmental Protection Agency (“EPA”) to provide financial assurance related to the Company’s environmental payments in accordance with the terms of the Consent Decree reached with the United States Department of Justice (“DOJ”) and EPA related to its liability for both OU-1 and OU-2 (see note 13 for additional information). The letter of credit expires on May 28, 2014 and requires an annual commitment fee of 0.125% and standby commission of 1%, and does not reduce amounts available under the 2012 Credit Facility.

On June 20, 2013, the Company entered into a Second Amendment and Joinder to Credit Agreement and to Security Agreement (the “Second Amendment”), which amends the 2012 Credit Facility in order to reflect the Reincorporation of the Company. The Second Amendment, among other things, joins the Company as a “Borrower” under the Credit Agreement and a “Debtor” under the Security Agreement entered into by SL-NJ in connection with the 2012 Credit Facility. In consideration for the Second Amendment, the Company incurred $28,000 in fees and expenses, which are amortized over the remaining life of the 2012 Credit Facility.

As of September 30, 2013, the Company had an outstanding balance of $3,500,000 under the 2012 Credit Facility. As of December 31, 2012 the Company had no outstanding balance under the 2012 Credit Facility. At September 30, 2013 and December 31, 2012, the Company had total availability under the 2012 Credit Facility of $36,026,000 and $39,510,000, respectively.

Income Tax

6. Income Tax

The Company calculates its interim tax provision in accordance with the provisions of ASC 740-270 “Income Taxes – Interim Reporting.” For each interim period the Company estimates its annual effective income tax rate and applies the estimated rate to its year-to-date income or loss before income taxes. The Company also computes the tax provision or benefit related to items separately reported, such as discontinued operations, and recognizes the items net of their related tax effect in the interim periods in which they occur. The Company also recognizes the effect of changes in enacted tax laws or rates in the interim periods in which the changes occur.

For the nine months ended September 30, 2013 and September 30, 2012, the estimated income tax rate from continuing operations was 27% and 31%, respectively. The decrease in the effective tax rate was primarily due to the recording of a research and development tax benefit of $906,000 in 2013, of which $431,000 was related to the retroactive reinstatement of the federal research and development tax credits from the enactment of the American Tax Relief Act of 2012. These credits were not available to the Company in 2012.

During the three months ended September 30, 2013, the Company recorded additional benefits from federal and state research and development tax credits of $245,000 and $67,000 respectively. During the nine months ended September 30, 2013, the Company recorded additional benefits from federal and state research and development tax credits of $741,000 and $165,000 respectively. The Company did not record additional benefits from federal and state research and development tax credits during the three and nine months ended September 30, 2012.

As of September 30, 2013, the Company’s gross research and development tax credit carryforwards totaled approximately $1,120,000. Of these credits, approximately $453,000 can be carried forward for 15 years and will expire between 2015 and 2028, and approximately $667,000 of state credits can be carried forward indefinitely.

The Company has recorded gross unrecognized tax benefits, excluding interest and penalties, as of September 30, 2013 and December 31, 2012 of $819,000 and $595,000, respectively. Tax benefits are recorded pursuant to the provisions of ASC 740 “Income Taxes.” If such unrecognized tax benefits are ultimately recorded in any period, the Company’s effective tax rate would be reduced accordingly for such period.

The Company has been examined by the Internal Revenue Service (the “IRS”) through the calendar year 2010. State income tax statutes are generally open for periods back to and including the calendar year 2008.

It is reasonably possible that the Company’s gross unrecognized tax benefits balance may change within the next twelve months due to the expiration of the statutes of limitation of the federal government and various state governments by a range of zero to $38,000. The Company records such unrecognized tax benefits upon the expiration of the applicable statute of limitations or the settlement with tax authorities. As of September 30, 2013, the Company has a liability for unrecognized benefits of $529,000 for federal taxes and $290,000 for state taxes. Such benefits relate primarily to expenses incurred in those jurisdictions.

The Company classifies interest and penalties related to unrecognized tax benefits as income tax expense. At September 30, 2013, and December 31, 2012, the Company has accrued approximately $97,000 and $62,000 for the payment of interest and penalties, respectively.

The final regulations regarding the deduction and capitalization of expenditures related to tangible property were issued during the third quarter of 2013 by the IRS. The Company has reviewed these regulations and does not intend to early adopt or amend any previously filed returns. The implementation of these regulations did not have a material impact on the Company’s consolidated financial statements for the year ending December 31, 2013.

Basis of Presentation

1. Basis Of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation. Operating results for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. These financial statements should be read in conjunction with the Company’s audited financial statements and notes thereon included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Unless the context requires otherwise, the terms the “Company,” “SL Industries,” “we,” “us” and “our” mean SL Industries, Inc., a Delaware corporation, and its consolidated subsidiaries after Reincorporation (defined and described below) and SL Industries, Inc., a New Jersey corporation prior to Reincorporation. In the context of describing the Reincorporation, “SL-NJ” means SL Industries, Inc., a New Jersey corporation, and “SL-DE” means SL Industries, Inc., a Delaware corporation and wholly owned subsidiary of SL-NJ.

On May 9, 2013, the Company’s shareholders voted to approve a proposal to change the state of incorporation of SL Industries from the State of New Jersey to the State of Delaware by merging SL-NJ with and into SL-DE (the “Reincorporation”). On June 20, 2013 (the “Effective Date”), the Reincorporation was effected by merging SL-NJ with and into SL-DE pursuant to an Agreement and Plan of Merger, dated June 3, 2012, between SL-NJ and SL-DE. SL-DE survived the merger and SL-NJ ceased to exist. The principal reason for the Reincorporation was to give the Company a greater measure of flexibility and simplicity in corporate governance and provide greater clarity and predictability with respect to the Company’s corporate legal affairs. The Reincorporation did not result in any change in the name, business, management, fiscal year, accounting, location of the principal executive officers, assets or liabilities or net worth (other than the costs of reincorporation which were immaterial) of the Company.

Commitments and Contingencies

13. Commitments and Contingencies

The Company is involved in certain legal and regulatory actions. Management believes that the ultimate resolution of such matters is unlikely to have a material adverse effect on the Company’s financial condition or results of operations, except as described below.

Litigation: The Company has been and is the subject of administrative actions that arise from its ownership of SL Surface Technologies, Inc. (“SurfTech”), a wholly-owned subsidiary, the assets of which were sold in November 2003. SurfTech formerly operated chrome-plating facilities in Pennsauken Township, New Jersey (the “Pennsauken Site”) and Camden, New Jersey (the “Camden Site”).

In 2006 the United States Environmental Protection Agency (the “EPA”) named the Company as a potential responsible party (a “PRP”) in connection with the remediation of the Puchack Well Field, which has been designated as a Superfund Site. The EPA is remediating the Puchack Well Field Superfund Site in two separate operable units. The first operable unit (“OU-1”) consists of an area of chromium groundwater contamination in three aquifers that exceeds the selected cleanup standard. The second operable unit (“OU-2”) pertains to sites that are allegedly the sources of contamination for the first operable unit. The EPA advised the Company in October 2010 that OU-2 includes soil contamination in the immediate vicinity of the Company’s Pennsauken Site.

In June 2011, the EPA announced a proposed plan for “cleaning up the soil” at OU-2. The remedy proposed by the EPA is “Geochemical Fixation.” This remedy involves applying a chemical reductant to the contaminated soil to reduce hexavalent chromium by converting it to immobilized trivalent chromium. The EPA’s estimated cost for this remedy is $20,700,000 over seven years. On September 26, 2011 the EPA issued a Record of Decision (“ROD”) selecting the Geochemical Fixation remedy.

The Company has reached an agreement with both the DOJ and EPA related to its liability for both OU-1 and OU-2 and has entered into a Consent Decree which governs the agreement, the terms of which are described below. The Company has agreed to perform the remediation for OU-2. Also, the Company has agreed to pay a fixed sum for the EPA’s past cost for OU-2 and a portion of the EPA’s past cost for OU-1. The payments are to be made in five equal payments of $2,141,000, for a total $10,705,000, plus interest. The Company has also agreed to pay the EPA’s costs for oversight of the OU-2 remediation. The United States District Court judge signed the Consent Decree effective April 30, 2013, thereby triggering the Company’s obligation under the Consent Decree. On May 10, 2013 the Company made the first payment related to its obligation under the Consent Decree in the amount of $2,185,000, which included interest. The next four payments will be made on the anniversary of the first payment plus ten days in the same amount of $2,141,000, plus interest. On May 28, 2013, a letter of credit in the amount of $8,564,000 was issued in favor of the EPA to provide financial assurance related to the Company’s remaining obligation to pay for the EPA’s past cost as mentioned above. Also, on July 19, 2013 the Company obtained financial assurance as required by the terms of the Consent Decree related to its obligations to remediate OU-2.

On December 3, 2012, the Company received a demand letter from the State of New Jersey. The demand is for $1,300,000 for past and future cleanup costs and $500,000 for natural resource damages (“NRD”) for a total of $1,800,000 (the “New Jersey Claim”). Although the Company and its counsel believe that it has meritorious defenses to any claim for reimbursement, the Company has offered to pay $250,000 to fully resolve the claim presented by the State of New Jersey for past costs, future costs and NRD at the Puchack Well Field Superfund site. The State of New Jersey is evaluating the Company’s counter-offer. Based on the current available information, the Company has estimated a total combined potential liability for OU-1 and OU-2 and the New Jersey Claim to be in the range of $17,911,000 to $29,295,000 The Company has recorded an accrual of $17,911,000 related to its combined liability related to this site. The estimated OU-2 remediation liability is based upon the EPA’s plan for remediation as provided in the ROD for OU-2 and the evaluation of data by the Company’s environmental engineering consultants. The liability for OU-1 and OU-2 is based upon the current terms of the Consent Decree.

Other

During 2012, the Company conducted an investigation to determine whether certain employees of SL Xianghe Power Electronics Corporation, SL Shanghai Power Electronics Corporation and SL Shanghai International Trading Corporation, three of the Company’s indirect wholly-owned subsidiaries incorporated and operating exclusively in China, may have improperly provided gifts and entertainment to government officials (the “China Investigation”). The Company had retained outside counsel and forensic accountants to assist in the China Investigation. Based upon the China Investigation, the estimated amounts of such gifts and entertainment were not material to the Company’s financial statements. Such estimates did not take into account the costs to the Company of the China Investigation itself, or any other additional costs.

The China Investigation included determining whether there were any violations of laws, including the U.S. Foreign Corrupt Practices Act (“FCPA”). The Company’s outside counsel contacted the DOJ and the Securities and Exchange Commission (the “SEC”) voluntarily to disclose that the Company was conducting an internal investigation, and agreed to cooperate fully. Additionally, the Company hired outside consultants to provide assistance in implementing a mandatory FCPA compliance program for all of its employees which was completed in December 2012. Also, during the first and second quarters of 2013 the Company engaged outside consultants to perform FCPA compliance tests at its operations in China and Mexico. On September 26, 2013, the DOJ notified the Company that it had closed its inquiry into this matter without filing criminal charges. The Company has not received an update from the SEC regarding the status of its inquiry. The Company cannot predict at this time whether any action may be taken by the SEC.

In the ordinary course of its business the Company is and may be subject to other loss contingencies pursuant to foreign and domestic federal, state and local governmental laws and regulations and may be party to certain legal actions, frequently involving complaints by terminated employees and disputes with customers, suppliers and others. In the opinion of management, any such other loss contingencies are not expected to have a material adverse effect on the financial condition or results of operations of the Company.

Environmental Matters: Loss contingencies include potential obligations to investigate and eliminate or mitigate the effects on the environment of the disposal or release of certain chemical substances at various sites, such as Superfund sites and other facilities, whether or not they are currently in operation. The Company is currently participating in environmental assessments and cleanups at a number of sites and in the future may be involved in additional environmental assessments and cleanups. Based upon investigations completed to date by the Company and its independent engineering-consulting firms, management has provided an estimated accrual for all known costs believed to be probable and costs that can be reasonably estimated in the amount of $22,020,000, of which $17,200,000 is included as other long-term liabilities, with the remainder recorded as other short-term accrued liabilities, as of September 30, 2013. However, it is the nature of environmental contingencies that other circumstances might arise, the costs of which are indeterminable at this time due to such factors as changing government regulations and stricter standards, the unknown magnitude of cleanup costs, and the unknown timing and extent of the remedial actions that may be required. These other circumstances could result in additional expenses or judgments, or offsets thereto. The adverse resolution of any one or more of these other circumstances could have a material adverse effect on the business, operating results, financial condition or cash flows of the Company. The Company’s environmental costs primarily relate to discontinued operations and such costs have been recorded in discontinued operations, net of tax.

There are three sites on which the Company may incur material environmental costs in the future as a result of past activities of its former subsidiary, SurfTech. There are two Company owned sites related to its former subsidiary, SurfTech. These sites are located in Pennsauken, New Jersey (the “Pennsauken Site”) and in Camden, New Jersey (the “Camden Site”). There is also a third site, which is not owned by the Company, referred to as the “Puchack Well Field Site.” The Puchack Well Field Site and the Pennsauken Site are part of the Puchack Well Field Superfund Site.

With respect to the Camden Site, the Company has reported soil contamination and a groundwater contamination plume emanating from the site. The New Jersey Department of Environmental Protection (“NJDEP”) approved, and the Company implemented in 2010, an interim remedial action pilot study to inject neutralizing chemicals into the unsaturated soil. Based on an assessment of post-injection data, our consultants believe the pilot study can be implemented as a full scale soil remedy to treat unsaturated contaminated soil. A Remedial Action Workplan for soils (“RAWP”) is being developed. The RAWP will select the injection remedy as the site wide remedy for unsaturated soils, along with demolition and proper disposal of the former concrete building slab and targeted excavation and disposal of impacted soil immediately underlying the slab. Additionally, the RAWP will address a small area of impacted soil off the property. The RAWP will be submitted to the NJDEP, by the Licensed Site Remediation Professional (“LSRP”) for the site. The RAWP is scheduled to be implemented in 2014. Also, the Company’s environmental consultants finalized an interim remedial action pilot study to treat on-site contaminated groundwater, consisting of injecting food-grade product, into the groundwater at the down gradient property boundary, to create a “bio-barrier.” The pilot study includes post-injection monitoring to assess the bio-barrier’s ability to treat contaminated groundwater. Implementation of the groundwater pilot study is currently underway with post-injection effectiveness monitoring expected to continue through 2014.

As previously reported, the Company is currently participating in environmental assessments and cleanups at a number of sites. One of these sites is a commercial facility, located in Wayne, New Jersey. Contaminated soil and groundwater has undergone remediation with NJDEP oversight, but contaminants of concern (“COCs”) in groundwater and surface water, which extend off-site, still remain above applicable NJDEP remediation standards. Certain COCs have also been detected in the indoor air of two commercial buildings, located on the property. One of the buildings (the “Main Building”) was outfitted with a sub-slab depressurization system as a mitigation measure. The source investigations under the Main Building were completed in June 2012. Soil and groundwater samples collected from underneath the Main Building identified COCs in excess of the NJDEP’s applicable remediation standards. Consequently, a soil contaminant source remains under the Main Building that is feeding the groundwater contamination. A soil remedial action plan will be required in order to remove the new soil source contamination by a second building that continues to impact groundwater. Our consultants have reviewed data to determine what supplemental remedial action is necessary for soils, and whether to modify or expand the groundwater remedy that will likely consist of additional in-situ injections of food grade product into the groundwater. Estimates have been developed by the Company’s consultants, which includes costs to enhance the existing vapor intrusion system, remedial injections, soil excavation and additional tests and remedial activities. Costs related to this site are recorded as part of discontinued operations, net of tax.

The Company has reported soil and groundwater contamination at the facility of SL-MTI located on its property in Montevideo, Minnesota. An analysis of the contamination has been completed and a remediation plan has been implemented at the site pursuant to the remedial action plan approved by the Minnesota Pollution Control Agency. The remaining steps under this plan are the monitoring of samples. Costs related to this site are recorded as a component of continuing operations.

As of September 30, 2013 and December 31, 2012, environmental accruals of $22,020,000 and $24,367,000, respectively, have been recorded by the Company in accrued liabilities – other and in other long-term liabilities, as appropriate (see Notes 11 and 12 for additional information).
