The Company

Note 1 — The Company

Gentherm Incorporated is a leading supplier of thermal seat comfort and cable systems to the global automotive industry. Unless the context otherwise requires, the terms “Company”, “we”, “us” and “our” used herein refer to Gentherm Incorporated. The term “historical Gentherm” used herein excludes W.E.T. Automotive Systems AG (“W.E.T.”), a subsidiary of Gentherm, Inc. See Note 3 regarding the acquisition of W.E.T. The Company performs design, development and manufacturing functions in locations aligned with our major customers’ product strategies in order to continue to grow and expand our business around the globe. We are working to expand application of our existing technologies into new markets and products and to develop and refine new technologies to make our existing products more efficient.

Historical Gentherm’s primary business is the sale of the Climate Control SeatTM (“CCS^TM or “CCS”) products to automobile and light truck original equipment manufacturers or their tier one suppliers. CCS provides year-round comfort to automotive seat occupants through both heating and cooling functions.

Since the initial introduction of CCS we have introduced new designs that incorporated improvements in electrical efficiency, size, weight, noise and versatility. These include our Micro Thermal Module™ (“MTM™” or “MTM”) technology, our CCS II configuration, and a heated and ventilated only variant of the CCS (“HV”). The HV relies on the use of ambient cabin air to provide cooling comfort instead of a thermo electric device (“TED”), like that found on our MTM and CCS II products. Further improvements in engineering design are currently in development and are expected to be introduced on future vehicle models.

The Company has also introduced an automotive heated and cooled cup holder and a heated and cooled suite of luxury mattresses to its product portfolio based on technology similar to that of the CCS system. The cup holder has been designed to be packaged in multiple configurations to accommodate different console environments. In addition to requiring low power consumption, it has proven automotive grade ruggedness, high reliability and drink retention features.

The Company is also engaged in a program to improve the efficiency of TEDs and to develop, market and distribute new products based on this technology. Included in this initiative is the development and testing of new materials that show increased thermoelectric efficiency.

On October 1, 2010 we formed Gentherm Europe, GmbH (“Gentherm Europe”) and opened a technical support office in Augsburg, Germany, to provide design initiatives, product development, application engineering and prototype builds in support of European sales.

As described in Note 3, the Company acquired a majority interest in W.E.T., a German publicly-traded company based in Odelzhausen, Germany on May 16, 2011. W.E.T. was established in 1968 and currently employs over 6,000 individuals at 14 locations. W.E.T.’s customers include passenger car OEMs, commercial vehicle OEMs and Tier 1 seat manufacturers.

W.E.T.’s major product categories include automotive seat comfort systems and specialized automotive cable systems. The automotive seat comfort systems category includes automotive seat heaters, climate comfort systems (similar to Gentherm’s climate controlled seat technology) for automotive seats, automotive steering wheel heater systems and integrated electronic components. The specialized automotive cable systems category includes ready-made wire harnesses and related wiring products. W.E.T. has been a manufacturer in the seat comfort segment since 1973.

While W.E.T.’s primary focus is on automotive original equipment markets, W.E.T. also offers product solutions to other customer groups, namely customer groups related to seat heating equipment for the automotive aftermarket, ski lifts and sports stadiums. These operations complement W.E.T.’s automotive seat comfort products, particularly in seat climate comfort systems in which ventilation systems are an integral part of the final product. Furthermore, W.E.T.’s customer base for other products extends beyond the automotive industry to the telecommunications and information technology industries.

W.E.T. maintains a global operational structure with manufacturing sites close to its key customers. W.E.T.’s European operations are primarily concentrated around its headquarters and customer service center in Odelzhausen, as well as its Hungarian and Ukrainian sites. W.E.T. operates four sites in North America, a customer service and research center located in Windsor, Canada, a warehouse facility located in Del Rio, Texas and two production sites located in Acuña, Mexico. In Asia, W.E.T. operates a low-cost production facility including customer service and research and development functions in Langfang, China and maintains representative offices in Seoul, South Korea and Tokyo, Japan. W.E.T.’s China operation was established in 2003 and serves the South Korean, Japanese, Chinese and certain European markets.

Summary of Significant Accounting Policies and Basis of Presentation

Note 2 — Summary of Significant Accounting Policies and Basis of Presentation

Consolidation

The consolidated financial statements at December 31, 2011 and 2012, reflect the consolidated financial position and consolidated operating results of the Company, W.E.T., Gentherm Europe GmbH and Gentherm Asia Pacific Inc. The consolidated financial statement at December 31, 2010 reflect the consolidated financial position and consolidated operating results of the Company, Gentherm Europe GmbH and Gentherm Asia Pacific Inc. Intercompany accounts have been eliminated in consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of less than 90 days to be cash equivalents. Cash balances in individual banks may exceed the federally insured limit by the Federal Deposit Insurance Corporation (the “FDIC”). From December 31, 2010 to December 31, 2012, the FDIC provided temporary unlimited deposit insurance. As of January 1, 2013, substantially all of the Company’s cash was uninsured.

Disclosures About Fair Value of Financial Instruments

The carrying amounts of all financial instruments, comprising cash and cash equivalents, short-term investments, accounts receivable and debt approximate fair value because of the short maturities of these instruments.

Use of Estimates

The presentation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Accrued Warranty Costs

The Company recognizes an estimated cost associated with its standard warranty on its products at the time of sale. The amount recognized is based on estimates of future failure rates and current claim cost experience. The following is a reconciliation of the changes in accrued warranty costs for the reporting period:


	December 31,
	2012			2011
Balance at beginning of year	$	8,487		$	1,261
Assumed warranty from W.E.T. at acquisition		—			6,979
Warranty claims paid		(347	)		(81	)
Expense		215			551
Adjustment due to currency translation		233			(223	)

Balance at end of year	$	8,588		$	8,487

Concentration of Credit Risk

Financial instruments, which subject the Company to concentration of credit risk, consist primarily of cash equivalents, short-term investments and accounts receivable. Cash equivalents consist of money market funds managed by major financial services companies. The credit risk for these cash equivalents is considered limited. The Company maintains an allowance for uncollectible accounts receivable based upon expected collectability and does not require collateral. As of December 31, 2012 JCI, Lear and Magna comprised 26%, 18% and 7% respectively, of the Company’s accounts receivable balance. As of December 31, 2011 Lear, JCI and Magna comprised 23%, 23%, and 8% respectively, of the Company’s accounts receivable balance. These accounts are currently in good standing.

Allowance for doubtful accounts

We record an allowance for doubtful accounts once exposure to collection risk of an accounts receivable is specifically identified. We analyze the length of time an accounts receivable is outstanding, as well as a customer’s payment history to determine the need for and amount of an allowance for doubtful accounts.

Inventory

The Company’s inventory is valued at the lower of cost (the first-in, first-out basis) or market. W.E.T.’s raw materials, consumables and commodities are measured at cost of purchase and unfinished and finished goods are measured at cost of production, using the weighted average method. If the net realizable value expected on the reporting date is below costs, a write-down is recorded to adjust inventory to its net realizable value. The Company provides a reserve for obsolete and slow moving inventories based upon estimates of future sales and product redesign. The following is a reconciliation of the changes in the inventory reserve (in thousands):


	December 31,
	2012			2011
Balance at beginning of year	$	1,127		$	572
Expense		1,307			532
Inventory write off		(215	)		(10	)
Adjustment due to currency translation		(34	)		33

Balance at end of year	$	2,185		$	1,127

Property and Equipment

Property and equipment, including additions and improvements, are recorded at cost less accumulated depreciation. Expenditures for repairs and maintenance are charged to expense as incurred. When property or equipment is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts. Gains or losses from retirements and disposals are recorded as operating income or expense.

Depreciation and amortization are computed using the straight-line method. The estimated useful lives of the Company’s property and equipment are as follows:


Asset Category		Useful Life
Plant and Equipment		2 to 20 years
Computer equipment and software		1 to 10 years
Leasehold improvements		Shorter of estimated life or term of lease
Production tooling		Estimated life of tool (2 to 5 years)
Buildings		5 to 50 years
Capital Leases		Shorter of useful life or term of lease
Furniture, fixtures and fittings		1 to 15 years

The Company recognized depreciation expense of $14,298, $8,954 and $1,148 for the three years ending December 31, 2012, 2011 and 2010, respectively.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets recorded in conjunction with the acquisition of W.E.T. were based on the Company’s estimate of fair value, as of the date of acquisition. The fair value and corresponding useful lives for acquired intangible assets were determined with the assistance of an independent third-party valuation firm and are listed below as follows:


Asset Category		Useful Life
Customer relationships		10-15 years
Order Backlog		0.5 years
Technology		8-9 years
Production Development Costs		4 years

Our business strategy largely centers on designing products based upon internally developed and licensed technology. When possible, we protect these technologies with patents. During the fourth quarter 2012, we changed our method of accounting for costs, all of which were external, associated with the application for patents. Prior to the change we capitalized the external legal and filing fees associated with new patent applications in addition to the cost of purchased patents. These costs were then amortized on a straight-line basis over their estimated economic useful lives which ranged from 4 to seventeen years. Under the new method, external legal costs are expensed as incurred and classified as research and development expenses in our consolidated statement of operations. We believe that this change is preferable because it will result in consistent treatment for all costs, that is, under our new method both internal and external costs associated with the application for patents are expensed as incurred. In addition, the change will provide a better comparison with our industry peers. Costs associated with the purchase of patents and patent rights, including those acquired in conjunction with a business combination, will continue to be capitalized as before. The change reduced operating income by $1,007, $1,073 and $774 for the three years ending December 31, 2012, 2011 and 2010, respectively. Basic and fully diluted earnings per share was reduced by $0.02, $0.03 and $0.02 for the three year ending December 31, 2012, 2011 and 2010, respectively.

We periodically review the recoverability and remaining life of our capitalized patents based upon market conditions, competitive technologies and our projected business plans. Change in these conditions could materially impact the carrying value for our capitalized patents.

On September 14 2012, W.E.T. purchased the rights and ownership of certain intellectual property from Johnson Controls for $7,000. The purchased intellectual property, used in the development and manufacturing of W.E.T.’s active cool seat comfort technology, has a useful life of seven years. Amortization of the purchased intellectual property will be recognized on a straight-line basis, of which approximately $285 was amortized during 2012.

A total of $2,522 in capitalized patent costs was amortized in 2012.

An estimate of total intangible asset amortization by year, including the aforementioned Johnson Control patents and those obtained through the acquisition of W.E.T., is as follows:


2013			15,917
2014			15,066
2015			13,618
2016			12,444
2017			11,296
Thereafter			27,363

Gentherm also has $166 of indefinite-lived trademark assets included in other intangible assets on our consolidated balance sheet as of December 31, 2012.

Impairments of Long-Lived Assets, Other Intangible Assets and Goodwill

Whenever events or changes in circumstances indicate that an asset’s carrying amount may not be recoverable, the Company will compare the carrying amount of the asset to the recoverable amount of the asset. The recoverable amount is defined as the greater of the asset’s fair value less costs to sell or its value in use. An impairment loss is recognized if the carrying amount of an asset exceeds the recoverable or fair value amount. An assessment of fair value could utilize quoted market prices, fair value appraisals, management forecasts or discounted cash flow analyses. No such triggering events occurred during the periods ended December 31, 2012, 2011 and 2010, respectively.

On an annual basis and at interim periods when circumstances require, the Company tests the recoverability of its goodwill. The goodwill test utilizes a two-step analysis, whereby the Company compares the carrying value of each identified reporting unit to its fair value. If the carrying value of the reporting unit is greater than its fair value, the second step is performed, where the implied fair value of goodwill is compared to its carrying value. The Company recognizes an impairment charge for the amount by which the carrying amount of goodwill exceeds its fair value. The fair values of the reporting units are estimated using the net present value of discounted cash flows, excluding any financing costs or dividends, generated by each reporting unit. The Company’s discounted cash flows are based upon reasonable and appropriate assumptions, which are weighted for their likely probability of occurrence, about the underlying business activities of the company’s reporting units. An impairment of goodwill from the acquisition of W.E.T. did not occur during the periods ending December 31, 2012 and 2011, respectively.

Product Revenues

Revenue from the sale of goods is recognized when the significant risks and rewards of ownership of the goods have been transferred to the buyer, the price can be measured reliably, recovery of consideration is probable and costs incurred or to be incurred from the transaction can be reasonably estimated. The Company sells its products under purchase order contracts issued by its customers. These contracts involve the sale of goods at fixed prices and provide for related transfer of ownership risk to the customer upon shipment from the Company’s warehouse location or in some cases upon receipt of the goods at the customers facility. Payment terms of these contracts range from 30 to 120 days from the date of shipment. The Company does not extend cash discounts for early payment.

Litigation Reserves

We record estimated future costs related to new or ongoing litigation. Recognition of litigation reserves are recorded when there is a current obligation from a past event, a claim is likely, and the amount of the obligation can be reliably measured. These estimates include costs associated with attorney fees and potential claims and assessments less any amounts recoverable under insurance policies.

Tooling

The Company incurs costs related to tooling used in the manufacture of products sold to its customers. In some cases, the Company enters into contracts with its customers whereby the Company incurs the costs to design, develop and purchase tooling and is then reimbursed by the customer under a reimbursement contract. Tooling costs that will be reimbursed by customers are included in prepaid expenses and other current assets at the lower of accumulated cost or the customer reimbursable amount. Approximately $1,878 and $1,140 of reimbursable tooling was capitalized within prepaid expenses and other current assets as of December 31, 2012 and 2011, respectively. Company-owned tooling is included in property and equipment and depreciated over its expected useful life, generally two to five years. Management periodically evaluates the recoverability of tooling costs, based on estimated future cash flows, and makes provisions, where appropriate, for tooling costs that will not be recovered.

Research and Development Expenses

Research and development activities are expensed as incurred. The Company groups development and prototype costs and related reimbursements in research and development. The Company recognizes amounts due as reimbursements for expenses as these expenses are incurred.

Income Taxes

We record income tax expense using the liability method which specifies that deferred tax assets and liabilities be measured each year based on the difference between the financial statement and tax bases of assets and liabilities at the applicable enacted Federal and State tax rates. A valuation allowance is provided for net deferred tax assets when management considers it more likely than not that the asset will not be realized. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. We recognize interest and penalties related to income tax matters in income tax expense.

Derivative financial instruments — hedge accounting

The Company accounts for some of its derivative financial instruments as cash flow hedges as defined in Financial Accounting Standards Board Accounting Standards Codification Topic 815. Since these derivatives are designated as hedging instruments for future anticipated cash flows, the effective portion of the gain or loss resulting from the valuation at the balance sheet date is recognized as a separate item within equity. The ineffective portion of the gain or loss is recognized in the income statement. These hedging transactions and the respective correlations meet the requirements for hedge accounting. The gains or losses recognized in equity are posted in the income statement when the hedged items are realized. Discounts or premiums for hedged contracts are recognized within earnings for the period, until maturity.

Net Earnings per Share

Basic earnings per share is computed by dividing net income by the weighted average number of shares of Common Stock. The Company’s diluted earnings per common share give effect to all potential shares of Common Stock outstanding during a period that are not anti-dilutive. In computing the diluted earnings per share, the treasury stock method is used in determining the number of shares assumed to be purchased from the conversion of Common Stock equivalents.

Stock Based Compensation

Share-based payments to employees, including grants of employee stock options are recognized in the financial statements as compensation expense based upon the fair value on the date of grant. The Company’s stock option compensation expense and related deferred tax benefit were $823 and $301, respectively, for the year ended December 31, 2012, $1,403 and $427, respectively, for the year ended December 31, 2011, and $1,275 and $259, respectively, for the year ended December 31, 2010.

Non-Controlling Interests

Effective January 1, 2009 we adopted ASC 810 “Consolidation”, which establishes accounting and reporting standards for the non-controlling interest in a subsidiary and for the retained interest in a gain or loss when a subsidiary is deconsolidated. ASC 810 requires that a non-controlling interest, previously referred to as a minority interest, be reported as part of equity in the Consolidated Financial Statements and that losses be allocated to the non-controlling interest even when such allocation might result in a deficit balance, reducing the losses attributable to the controlling interest. Non-controlling interest reported in the Consolidated Statements of Operations and Consolidated Statements of Shareholders’ Equity for the periods ended December 31, 2012 and 2011 represent the 24.08% and 24.12%, respectively of W.E.T.’s outstanding voting stock not acquired in share purchases.

At the first annual meeting of shareholders of W.E.T. following our acquisition, held on August 16, 2011, the shareholders of W.E.T. approved an arrangement by which Gentherm Europe will take management control of W.E.T. and will directly receive W.E.T.’s annual profits and absorb W.E.T.’s annual losses, subject to certain conditions and obligations of Gentherm Europe. Such an arrangement (a “Domination and Profit and Loss Transfer”) is somewhat unique to German law and is subject to the terms and conditions applicable thereto under German law. Due to litigation filed in opposition to the Domination and Profit and Loss Transfer, registration of the Domination and Profit and Loss Transfer did not occur until February 22, 2013.

Under the Domination and Profit and Loss Transfer arrangement: (1) Gentherm Europe will absorb all annual losses incurred by W.E.T., (2) for as long as the Domination and Profit and Loss Transfer remains in effect, the minority shareholders of W.E.T. will be guaranteed a recurring, annual payment (the “Guaranteed Compensation”) of EUR 3.71 per share, subject to statutory taxes and deductions, resulting in a net payment of EUR 3.17 per share, and (3) the minority shareholders of W.E.T. can elect to forego the Guaranteed Compensation and instead tender their shares to Gentherm Europe (the “Tender Option”) for a one-time cash payment of EUR 44.95 per share provided that the Tender Option can only be exercised during the two month period after the registration of the Domination and Profit and Loss Transfer is completed, and further provided that Gentherm has agreed to increase this payment to EUR 85.00 per share in connection with the settlement of the litigation in opposition to the Domination and Profit and Loss Transfer. The Domination and Profit and Loss Transfer has an indefinite term, but can be terminated by Gentherm Europe or W.E.T. anytime after five years from the effective date.

For the period ended December 31, 2010, a 15% percent non-controlling interest in Gentherm’s former subsidiary BSST, now Advanced Technology, was held by former BSST President and CEO Dr. Lon Bell.

Subsequent Events

On February 15, 2013, historical Gentherm acquired 442,253 shares in W.E.T., representing approximately 14% of the total outstanding shares in W.E.T., through a transaction agreement with W.E.T.’s largest minority shareholder. The Company paid 3,300,000 shares of Gentherm common stock and cash payments of €5,408, or $7,247, for these shares. We have since acquired an additional 300,651 shares in W.E.T., pushing our total ownership interest in W.E.T. to approximately 99%. These additional shares were purchased at a price €85 per share for a total of €25,556, or $34,245. Gentherm borrowed an additional $43,429 from the US Bank of America credit facility in connection with the purchase of these shares.

W.E.T. Acquisition

12 Months Ended

Dec. 31, 2012

W.E.T. Acquisition

Note 3 — W.E.T. Acquisition

As described in Note 1, W.E.T develops, manufactures and distributes thermal comfort systems, interior equipment and specialized cable systems used in automobile seats and other automotive and electronic applications in the automotive industry.

On May 16, 2011, the Company completed the previously announced acquisition of W.E.T. through our wholly-owned subsidiary, Gentherm Europe. A total of 2,316,175 shares, representing 76.19 percent of the outstanding voting stock of W.E.T., were tendered to Gentherm in response to Gentherm’s tender offer of €40 per share. An additional 2,903 shares were tendered at the same price on May 26, 2011 pursuant to an additional acceptance period of the tender offer bringing the total percentage acquired to 76.28. The total purchase price for the acquisition was €92,763, or $130,889, in cash plus the assumption of €36,322, or $51,570, in debt obligations less €12,372, or $17,457, in cash acquired. In August 2011, W.E.T. sold 16,305 of W.E.T. AG treasury shares to an independent third party buyer at a price of €50 per share, or approximately $67.97 per share.

On May 16, 2012, W.E.T. AG sold all 143,683 remaining treasury shares to existing shareholders, on a pro-rata basis, for €44.95 per share. Shares that were not purchased were offered to the other shareholders that exceeded their pro-rata allocation to purchase treasury shares. Gentherm purchased 110,325 W.E.T. AG treasury shares for approximately $6,400. During 2012, Gentherm acquired an additional 2,660 shares of W.E.T on the open market. As of December 31, 2012, Gentherm’s total percentage ownership in W.E.T. AG was 76 percent.

Prior to the acquisition, Gentherm and W.E.T. were engaged in lawsuits concerning intellectual property. These lawsuits were settled upon consummation of the acquisition. No gain or loss for the lawsuit was recorded in conjunction with the W.E.T. acquisition.

Goodwill

We recorded goodwill from the acquisition of W.E.T. Automotive Systems AG. It is estimated that none of the goodwill recognized will be deductible for income tax purposes. A roll forward of goodwill from the acquisition date May 16, 2011 to December 31, 2012 is as follows:


May 16, 2011	$	24,922
Purchase price allocation adjustment		1,506
Exchange rate impact		(2,183	)

December 31, 2011	$	24,245
Exchange rate impact		(484	)

December 31, 2012	$	24,729

Purchase Price Allocation

The purchase price of approximately $130,889, net of cash acquired of $17,457, has been allocated to the values of assets acquired and liabilities assumed as of May 16, 2011. The allocation is as follows:


Accounts receivable	$	57,470

The Company has Net Operating Loss (“NOL”) carryforwards as follows:


Jurisdiction	Amount as of December 31, 2012		Years of Expiration
U.S. Federal income tax	$	10,165		2012 - 2023
State income taxes	$	4,002		2014 - 2016

All of the U.S. Federal NOLs were incurred prior to the June 8, 1999 Preferred Financing, which qualified as a change in ownership under Section 382 of the Internal Revenue Code (“IRC”). Due to this change in ownership, the NOL accumulated prior to the change in control can only be utilized against current earnings up to a maximum annual limitation of approximately $591. As a result of the annual limitation, approximately, $6,025 remaining of these carryforwards are expected to expire before ultimately becoming available to reduce future tax liabilities in addition to $13,324 in NOL’s generated prior to the change in control which have already expired without being utilized. Consequently, the related valuation allowance decreased by $1,503 during 2012. During 2010, we completed a study related to the 1999 change in control limitation amount and determined that an additional $4,044 NOL’s subject to the limitation were utilizable during 2010. We reversed the portion of the valuation allowance related to this adjustment totaling $1,375. A second change in control took place on September 22, 2006 when an accumulation of trades of the Company’s Common Stock by certain of the Company’s large shareholders exceeded a three year cumulative amount of 50% of the Company’s total Common Stock outstanding. The resulting annual change in control limitation of approximately $8,135 did not have an impact on the utilization of the amounts of the NOLs subject to this limitation.

Since our NOLs offset our current federal tax liability, we do not recognize for book purposes deductions allowed for stock option exercises in excess of that recorded for book purposes. As such, our deferred tax asset for book purposes related to NOLs is less than the actual NOL available. During 2011, our taxable income exceeded the remaining amount of NOLs recorded for book purposes representing a benefit attributable to deductions taken for tax purposes on stock option exercises. We recorded this benefit which totaled $171 and $3,275 for 2012 and 2011, respectively, directly to paid-in capital.

The earning before for income taxes and our tax provision are comprised of the following:

The Company’s earnings outside the US are permanently reinvested. With respect to the German operations all amounts are permanently reinvested other than the earnings of certain jurisdictions for which deferred income taxes have been provided. Quantification of the deferred tax liability, if any, associated with indefinitely reinvested basis differences is not practicable.

The American Taxpayer Relief Act of 2012 (“the Act”) was signed into law on January 2, 2013. The Act retroactively restored the research and development credit and certain exemptions under the foreign income tax rules. Because a change in tax law is accounted for in the period of enactment, the retroactive effect of the Act on the Company’s U.S. federal taxes for 2012, a benefit of approximately $1.3 million will be recognized in 2013.

The Company is subject to U.S. federal income tax as well as income tax in multiple foreign and state jurisdictions. During 2010, the Internal Revenue Service (“IRS”) completed a review of our 2007 and 2008 Federal Income Tax Returns. Our 2010 and 2011 Federal tax returns are currently under audit. No state tax returns are currently under examination.

The reconciliation of the beginning and ending amount of unrecognized tax benefits that would favorably affect the effective income tax rate in the future periods is as follows:

12 Months Ended

Dec. 31, 2012

Debt

On March 30, 2011, we and our subsidiary, Gentherm Europe, entered into a credit agreement with a syndicate of banks led by Bank of America (the “US Bank of America credit facility”) and W.E.T. and W.E.T. Automotive Systems Ltd., a Canadian corporation wholly owned by W.E.T., entered into a credit facility with the same syndicate of banks (the “W.E.T. Bank of America credit facility”). We cancelled our then existing credit facility with Comerica Bank. The W.E.T. Term Note proceeds were used to repay then existing W.E.T. senior indebtedness.

The US Bank of America credit facility provided two term notes (referred to as the “US Term Note and Europe Term Note”) and a revolving line of credit note (“US Revolving Note”). The W.E.T. Bank of America credit facility provided W.E.T. with a term note (“W.E.T. Term Note”) and a revolving line of credit note (“W.E.T. Revolving Note”).

On March 30, 2012, the Company entered into the fourth amendment to the US Bank of America credit facility. This amendment removed the requirement that previously obligated Gentherm to make prepayments on its outstanding indebtedness equal to the net proceeds received from the sale of Gentherm common stock in excess of the future obligations owed to the holders of Gentherm’s Series C Convertible Preferred Stock. This amendment permits Gentherm to retain any such excess amounts for general corporate purposes.

On May 16, 2012, W.E.T. sold all remaining shares of its treasury stock to current shareholders. In accordance with the terms of the W.E.T. Bank of America credit facility, net proceeds from the sale of treasury shares, including approximately $6,353 paid by historical Gentherm, were used to pay down the outstanding indebtedness on the W.E.T. term note. W.E.T. made a payment of $8,237 on the euro denominated tranche of the W.E.T. term note.

On December 17, 2012, Gentherm, Gentherm Europe, W.E.T. and the syndicate of banks led by Bank of America entered into amendments of the US Bank of America the W.E.T. Bank of America credit facilities. The US Bank of America credit facility amendment extended both the availability period for draws and the start of the repayment period under the Europe Term Note from January 1, 2013 to June 30, 2014, as well as increased the amount available under the US Revolving Note from $25,000 to $30,000. The W.E.T. Bank of America credit facility amendment increased the amount available under the W.E.T. Revolving Note from €10,000 to €20,000.

The US Term Note and Europe Term Note are subject to quarterly principal payments, with total principal amortization of 10% of the original principal amount in the first year and amortization of 12.5%, 15%, 17.5% and 10% of the original principal amount during years two, three, four and five, respectively with all remaining amounts owing under each term facility due and payable in full at the term loan maturity date. The W.E.T. Term Note is subject to quarterly principal payments totaling 20% annually. With the exception of the Europe Term Note, whose availability period for draws has been extended by 18 months, principal outstanding under the US Term Note and US Revolving Note and W.E.T. Bank of America credit facility will be due and payable in full on March 30, 2016. The Europe Term Note will be due and paid in full on September 30, 2018. Interest is payable at least quarterly. The Company has the option to elect interest rates based on either a Eurocurrency (LIBOR or EUIBOR) rate (“Eurocurrency Rate Loans”) (0.20% – 0.40% at December 31, 2012) or a base rate (“Base Rate Loans”) plus a margin (“Applicable Rate”), which varies based on the Consolidated Leverage Ratio of the Company, as defined by the US and W.E.T. Bank of America credit agreements. The base rate is equal to the highest of the Federal Funds Rate (0.09% at December 31, 2012) plus 0.5%, Bank of America’s prime rate (3.25% at December 31, 2012), or a one month Eurocurrency rate plus 1.0%. The Applicable Rate for the current period was 1.75% for Eurocurrency Rate Loans and 0.75% for Base Rate Loans.

No amounts were outstanding under either the US Revolving Note or the W.E.T. Revolving Note as of December 31, 2012 and $29,550 and €20,000 were available under each note, respectively. Gentherm also has an outstanding Letter of Credit of $450,000 as of December 31, 2012.

On September 11, 2012, we borrowed ¥20,000, or $3,159, from Bank of China to fund a plant expansion project in China. The Bank of China loan is due in lump sum on September 10, 2013 with interest calculated at a fixed rate of 6.9%.

The Company must maintain certain financial ratios including a minimum Consolidated Fixed Charge Coverage Ratio and a maximum Leverage Ratio as defined by the Bank of America credit agreement. The loans are secured by all of the Company’s assets.

As of December 31, 2012, we were in compliance with all terms as outlined in the credit agreement for each of the US Bank of America credit facility, the W.E.T. Bank of America credit facility and the Bank of China loan.

Series C Convertible Preferred Stock

12 Months Ended

Dec. 31, 2012

Series C Convertible Preferred Stock

Note 7 — Series C Convertible Preferred Stock

On March 31, 2011, we issued 7,000 shares of our Series C Convertible Preferred Stock (each a “Preferred Share” and, collectively, the “Preferred Shares”) having an initial stated value of $10,000 per Preferred Share, subject to adjustment. We received approximately $64,013 in net proceeds from the sale, after deducting placement agent fees and other offering expenses which totaled $5,987. We used the net proceeds from this offering to fund, in part, the W.E.T. acquisition.

If the W.E.T. acquisition had not been completed prior to July 1, 2011, we would have redeemed all of the Series C Convertible Preferred Stock then outstanding, at a redemption price equal to 102.5% (“No Acquisition Redemption Premium”) of the aggregate stated value of the Series C Convertible Preferred Stock, plus accumulated and unpaid dividends up to, but not including, the redemption date. We would have also then issued certain warrants (“No Acquisition Warrants”). The No Acquisition Redemption Premium and No Acquisition Warrants represent embedded liability derivatives and have been bifurcated for recording purposes. The estimated fair value recorded of the No Acquisition Redemption Premium and the No Acquisition Warrants as of the March 30, 2011 issue date were $700 and $1,910, respectively. Since the W.E.T. acquisition was completed by July 1, 2011, the No Acquisition Redemption Premium expired and the No Acquisition Warrants will not be issued and therefore the fair value was equal to zero at June 30, 2011.

The liquidation preference with respect to each share of Series C Convertible Preferred Stock is the greater of (i) the sum of the stated value, accrued and unpaid dividends and the amount of all future dividends through the maturity date that would have been received in the absence of liquidation; and (ii) an amount that a holder would have received in liquidation had the Series C Convertible Preferred Stock been converted immediately prior to the event of liquidation.

Holders of the Series C Convertible Preferred Stock are entitled to receive, out of funds legally available therefore, dividends payable in cash (if permitted under the US Bank of America credit facility), our Common Stock (if certain equity conditions are satisfied or waived as of the applicable date), or any combination thereof, at the election of the Company, at the rate of 8% per annum of the stated value, payable quarterly in arrears on September 1, December 1, March 1 and June 1 of each year, commencing September 1, 2011. Dividends on our Series C Convertible Preferred Stock are cumulative from the date of initial issuance.

The Series C Convertible Preferred Stock is to be redeemed in nine equal quarterly installments beginning on September 1, 2011 and ending on September 1, 2013 (each, an “Amortization Date”) by paying cash, issuing shares of our Common Stock or any combination thereof for $10,000 per Preferred Share plus accumulated and unpaid dividends. Total Series C Convertible Preferred Stock installments made during the twelve month period ended December 31, 2012 is as follows:


	Installment Payment		Cash		Stock ($)		Stock (shares)
Dividend	$	3,431	$	2,400	$	1,031		80,169
Principal		31,120		23,340		7,780		600,309

Total	$	34,551	$	25,740	$	8,811		680,478

Total Series C Convertible Preferred Stock installments made during the twelve month period ended December 31, 2011 is as follows:


	Installment Payment		Cash		Stock ($)		Stock (shares)
Dividend	$	3,604	$	1,362	$	2,242		193,838
Principal		15,560		7,780		7,780		672,593

Total	$	19,164	$	9,142	$	10,022		866,431

We may, at our option, elect to pay the quarterly amortization amount on each Amortization Date if certain conditions are satisfied or waived as of the relevant notice date through the relevant Amortization Date, in shares of common stock, in cash (if permitted under the Bank of America credit facility), or in any combination of shares and cash. To the extent that we pay all or any portion of a quarterly amortization amount in shares of common stock, if the equity conditions are satisfied or waived as of the applicable notice date through the applicable Amortization Date, we will deliver on the applicable Amortization Date a number of shares of common stock equal to (i) the applicable quarterly installment amount being paid in shares of common stock divided by the lower of (A) the conversion price for the Series C Convertible Preferred Stock and (B) the Market Price (as defined below) determined as of the applicable Amortization Date less (ii) any Pre-Installment Shares (as defined below) with respect to such installment. If we pay all or any portion of a quarterly amortization amount in shares of common stock, we will be required to deliver a number of shares of common stock to the holders of the Series C Convertible Preferred Stock twenty three (23) trading days prior to the applicable Amortization Date equal to the portion of applicable quarterly amortization amount determined by us to be paid in shares of common stock divided by the lower of (A) the conversion price for the Series C Convertible Preferred Stock and (B) the Market Price determined as of the trading day prior to such date (such shares “Pre-Installment Shares”).

The “Market Price” means a ten percent (10%) discount to the arithmetic average of the lowest fifteen (15) volume weighted average prices of the common stock during the twenty (20) consecutive trading day period ending two (2) trading days prior to each applicable date of determination.

Holders of the Series C Convertible Preferred Stock may convert their shares at any time into shares of common stock at a conversion price of $15.83, including the conversion of accrued but unpaid dividends per Preferred Share then remaining into shares of common stock, and in addition will be entitled to a make-whole amount that would apply in a conversion (reflecting dividends that would have been payable through maturity if the Series C Convertible Preferred Stock had remained outstanding); provided, however, that under certain conditions where our Bank of America credit facility prohibits payment of the make-whole amount, we will only be obligated to pay such make-whole amount at the time such amount, or portion thereof, would have been due to be paid as a dividend as if the Series C Convertible Preferred Stock at issue had not been converted.

The Series C Convertible Preferred Stock is subject to mandatory redemption at the election of a holder upon the occurrence of certain triggering events as defined in our articles of incorporation. The redemption price per Preferred Share in these circumstances would be the greater of (i) 125% of the stated value plus accrued dividends, and (ii) the conversion rate then in effect (which rate reflects the number of shares of common stock into which each share of the holder’s Series C Convertible Preferred Stock may be converted) multiplied by the highest closing sale price of our common stock during the period beginning immediately prior to the triggering event and ending on the date the holder delivers a notice of redemption, plus in each case the additional make-whole amount that would apply in a conversion (reflecting dividends that would have been payable through maturity if the Preferred Shares had remained outstanding).

Holders of Series C Convertible Preferred Stock do not have any voting rights except as specifically provided in our articles of incorporation or as otherwise required by law.

With respect to dividend rights and rights upon liquidation, winding up or dissolution, our Series C Convertible Preferred Stock will be:

•

junior to all of our existing and future indebtedness;

•

junior to each other class or series of our capital stock other than (i) our common stock and any other class or series of our capital stock the terms of which provide that such class or series will rank junior to the Preferred Shares and (ii) any other class or series of our capital stock, the terms of which provide that such class or series will rank on parity with the Preferred Shares;

•

on parity with any class or series of our capital stock the terms of which provide that such class or series will rank on parity with the Preferred Shares;

•

senior to our common stock and any other class or series of our capital stock the terms of which provide that such class or series will rank junior to the Preferred Shares; and

•

effectively junior to all of our subsidiaries’ (i) existing and future liabilities and (ii) capital stock held by others.

Pursuant to the terms of the Series C Convertible Preferred Stock, we will not, without the prior written consent of holders of the Series C Convertible Preferred Stock, incur indebtedness in excess of (i) $150 million (with any amount thereunder in Euro converted to U.S. Dollars at the exchange rate on the date of initial issuance of the Preferred Shares) under the Bank of America credit facility and (ii) the aggregate amount of additional indebtedness permitted under the Bank of America credit facility.

The following table summarizes the Series C Preferred Stock activity during the two year period ended December 31, 2012:

Accounting for Stock Based Compensation

Note 8 — Accounting for Stock Based Compensation

On May 10, 2012, the shareholders of the Company approved to amend the Gentherm Incorporated 2011 Equity Incentive Plan (the “2011 Plan”) to authorize an additional 2,000,000 shares of common stock to be available for issuance under this plan. The 2011 Plan permits the granting of various awards including stock options (including both nonqualified options and incentive options), stock appreciation rights, restricted stock and restricted stock units, performance shares and certain other awards to key employees, outside directors and consultants and advisors of the Company. In addition to the 2011 Plan, the Company issued options under the Amended and Restated 2006 Stock Incentive Plan (the “2006 Plan”), the Amended and Restated 1997 Stock Incentive Plan (the “1997 Plan”) and the 1993 Stock Option Plan (the “1993 Plan” and, together with the 2011 Plan, the 2006 Plan and the 1997 Plan, the “Plans”). As of December 31, 2012 the Company had an aggregate of 2,304,000 shares of common stock available to issue under the 2011 Plan, 8,578 shares of common stock available to issue under the 2006 Plan and no shares available to issue under the 1993 Plan or the 1997 Plan.

The 2006 Plan expires in May 2016. The 1997 plan and the 1993 Plan each expired in April 2007 and April 2003, respectively; however, certain options issued under such plans have not expired. The Plans are administered by the Board of Directors. The selection of participants, allotment of shares, determination of price and other conditions are determined by the Board of Directors at its sole discretion, in order to attract and retain personnel instrumental to the success of the Company. Stock options granted under the Plans have lives for a period of up to ten years from the date of grant at an exercise price which is not less than the fair market value of the Common Stock on the date of the grant.

Options are generally granted with various vesting periods generally ranging between three to five years for employees and one year for directors. Option vesting may be accelerated at the discretion of the Board of Directors.

The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. This model incorporates certain assumptions for inputs including a risk-free interest rate, expected dividend yield of the underlying common stock, expected option life and expected volatility in the market value of the underlying common stock. The following assumptions were used for options issued in the following periods:


	2012			2011			2010
Expected volatility		47	%		49 - 55	%		48	%
Weighted average expected volatility		47	%		55	%		48	%
Expected lives		3 yrs.			3 - 5 yrs.			5 yrs.
Risk-free interest rate		0.43	%		0.37 - 0.94	%		2.69	%
Expected dividend yield		none			none			none

Expected volatilities are based on the historical volatility of the Company’s common stock and that of an index of companies in our industry group. Since the Company has little historical data to help evaluate the expected lives of options, we considered several other factors in developing this assumption including the average holding period of outstanding options, their remaining terms and the cycle of our long range business plan. The risk-free interest rate is based upon quoted market yields for United States Treasury debt securities. The expected dividend yield is based upon the Company’s history of having never issued a dividend and management’s current expectation of future action surrounding dividends. Based on our historical experience, we do not expect any of the options granted to be forfeited.

The following table summarizes stock option activity during the three year period ended December 31, 2012:


Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term		Aggregate Intrinsic Value

Earnings per share

Note 9 — Earnings per share

The Company’s diluted earnings per share give effect to all potential common shares outstanding during a period that do not have an anti-dilutive impact to the calculation. In computing the diluted earnings per share, the treasury stock method is used in determining the number of shares assumed to be purchased from the conversion of Common Stock equivalents. The following summarizes the shares included in the dilutive shares as disclosed in the statements of operations:


	Year ended December 31,
	2012		2011		2010
Weighted average number of shares for calculation of basic EPS — Common Stock		28,352,864		22,605,518		21,716,775
Stock options under Plans		509,599		849,104		779,472

Weighted average number of shares for calculation of diluted EPS — Common Stock		28,862,463		23,454,622		22,496,247

The accompanying table represents Common Stock issuable upon the exercise of certain stock options and Series C Convertible Preferred Stock that have been excluded from the diluted earnings calculation because the effect of their inclusion would be anti-dilutive.

Shareholder Rights Plan

Shareholder Rights Plan

Note 12 — Shareholder Rights Plan

The Company’s Board of Directors has the authority to issue up to 4,991,000 shares of Preferred Stock and to determine the price, rights (including conversion rights), preferences and privileges of those shares without any further vote or action by the shareholders. Consistent with this authority, in January, 2009 our Board adopted a Shareholder Rights Plan (the “Rights Plan”) in which one purchase right was distributed as a dividend on each share of common stock held of record as of the close of business on February 10, 2009 (the “Rights”). If exercisable, each Right will entitle its holder to purchase from the Company one one-thousandth of a share of a newly created Series B Preferred Stock of the Company for $20.00 (the “Purchase Price”). The Rights will become exercisable if any person or group becomes the beneficial owner of 15% or more of the Company’s common stock or has commenced a tender or exchange offer which, if consummated, would result in any person or group becoming the beneficial owner of 15% or more of the Company’s common stock. If any person or group becomes the beneficial owner of 15% or more of the Company’s common stock, each right will entitle its holder, other than the acquiring person, to purchase a number of shares of the Company’s or the acquiror’s common stock having a value of twice the Purchase Price. The Rights are deemed attached to the certificates representing outstanding shares of common stock.

Segment information is used by management for making operating decisions and assessing the performance of the Company. Essentially, management evaluates the performance of its segments based primarily on operating income. Such accounting policies are the same as those described in Note 2.

The Company’s reportable segments are as follows:

•

Climate Control Seats (CCS) — variable temperature seat climate control system designed to improve the temperature comfort of automobile passengers produced by historical Gentherm. This segment also includes the heated and cooled cup holder and heated and cooled mattress divisions to which results individually are not currently significant.

•

Advanced Technology (formerly BSST) — a division engaged in research and development efforts to improve the efficiency of thermoelectric devices and to develop, market and distribute products based on this technology.

•

W.E.T. — The W.E.T. acquisition is being evaluated currently as an individual segment until such time as Gentherm is able to fully evaluate and implement its future integration plans and strategy.

The tables below present segment information about the reported product revenues and operating income of the Company for years ended December 31, 2012, 2011 and 2010. Asset information by segment is not reported since the Company does not manage assets at a segment level at this time.

Executive Nonqualified Defined Benefit Plan

Executive Nonqualified Defined Benefit Plan

Note 14 — Executive Nonqualified Defined Benefit Plan

On August 8, 2008 the Company established The Executive Nonqualified Defined Benefit Plan of Gentherm Incorporated (the “Plan”), an unfunded executive pension plan, with an effective date of April 1, 2008. Daniel Coker, the Company’s President and Chief Executive Officer, is expected to be the only participant in the Plan which will, if fully vested, provide for fifteen annual retirement benefit payments of $300,000 each beginning January 1, 2018. Mr. Coker will become entitled to receive such retirement benefit payments, or a portion thereof, through his continuous service to the Company as follows: Mr. Coker will become proportionally vested in the benefit over a six year period starting on April 1, 2011.

The Company records a projected benefit obligation representing the present value of future plan benefits when earned by the participant. The following table sets forth the benefit obligation, amounts recognized in the Company’s financial statements and the principal assumptions used:


	2012		2011		2010
Change in projected benefit obligation:
Benefit obligation at beginning of year	$	1,142	$	688	$	377
Service cost		317		263		228
Interest cost		45		36		23
Actuarial loss		129		155		60

Net periodic benefit cost		491		454		311

Benefit obligation at end of year	$	1,633	$	1,142	$	688

The benefit obligation is included in the Company’s consolidated balance sheet as a non-current liability. Service and interest cost is included in selling, general and administrative expenses in the Company’s consolidated statements of operations and actuarial losses are included the Company’s consolidated balance sheet as part of accumulated other comprehensive income within shareholders’ equity. Actuarial losses are amortized to selling, general and administrative expense in the Company’s consolidated statements of operations based on the average future service life of the Plan. A discount rate assumption of 3.25%, 4.0% and 5.25% was used to determine the benefit obligation and the net periodic service cost for years ended December 31, 2012, 2011 and 2010, respectively.

Although the Plan is not funded, the Company has established a separate trust having the sole purpose of paying benefits under the Plan. The only asset of the trust is a corporate-owned life insurance policy (“COLI”) on the life of Oscar Marx III, the Chairman of the Company’s Board of Directors. The COLI is valued at fair value using quoted prices listed in active markets (Level 1 input based on the U.S. GAAP fair value hierarchy). The policy value of the COLI was $1,466 and $1,102 as of December 31, 2012 and 2011, respectively, and was included in other non-current assets.

W.E.T. has an established defined benefit plan for retired and current members of its executive management team.

W.E.T. records a projected benefit obligation representing the present value of future plan benefits when earned by the participant. The following table sets forth the benefit obligation and amounts recognized in the Company’s financial statements:


	2012			2011
Change in projected benefit obligation:
Benefit obligation at beginning of year	$	4,250		$	4,280
Service cost		199			7
Interest cost		195			118
Paid pension distributions		(277	)		(167	)

Past service cost		—			67
Exchange rate impact		113			—

Benefit obligation at end of year	$	5,392		$	4,250

The following table sets forth the fair value of the plan assets from the date of acquisition to December 31, 2012:


	2012			2011
Change in plan assets:
Plan assets at beginning of year	$	1,098		$	943
Expected return on plan assets		41			21
Net contributions		386			148
Actuarial loss		(11	)		(4	)

The beginning of year balance for both the W.E.T. pension benefit obligation and pension plan asset rollforward represents the estimated benefit obligation and pension plan asset fair value as of May 16, 2011, the date the acquisition of W.E.T. Automotive Systems was completed.

The W.E.T. defined benefit plan is underfunded by $3,844 and $3,152 as of December 31, 2012 and 2011, respectively. The portion of the net benefit obligation payable within the next 12 months is included in the Company’s consolidated balance sheet within accrued liabilities. The long-term portion of the net benefit obligation is included in pension benefit obligation. The net periodic benefit cost is included in selling, general and administrative expenses in the Company’s consolidated statement of operations. The following table describes the actuarial assumptions used to determine the benefit obligation and the net periodic service cost:


	2012
Discount rate		3.41	%
Expected long term rate of return on plan assets		3.80	%

Plan assets are comprised of W.E.T’s. pension insurance policies and are pledged to the beneficiaries of the plan. Fair value of the pension insurance policies is determined on the basis of the calculation of the underlying insurance charge. Due to the basis of the calculation, pension plan assets are determined to be Level 2 investments. The expected return on plan assets assumption used to calculate WET’s pension benefit obligation was determined using actual returns realized on plan assets in the prior year.

The schedule of expected pension payments made to W.E.T. defined benefit plan participants over the next 10 years is as follows:

Fair Value Measurement

Dec. 31, 2012

Fair Value Measurement

Note 15 — Fair Value Measurement

The Company bases fair value on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We have adopted a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value.

Except for derivative instruments and hedging activities, and pension liabilities and plan assets, the Company has no financial assets and liabilities that are carried at fair value at December 31, 2012 and 2011. The carrying amounts of financial instruments comprising cash and cash equivalents, and accounts receivable approximate their fair values due to their short-term nature. The carrying value of the Company’s long-term debt approximates its fair value because interest charged on the loan balance is variable. See Note 6 for a description of Company’s debt and corresponding rates of interest. See Note 16 regarding the fair value of derivative instruments and hedging activities. See Note 14 regarding the fair value of pension liabilities and plan assets.

Certain Company assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value may not be recoverable. As of December 31, 2012 and 2012, the Company did not realize any changes to the fair value of these assets due to events that negatively impacted their recoverability.

- Definition

The entire disclosure of the fair value measurement of assets and liabilities, which includes financial instruments measured at fair value that are classified in shareholders' equity, which may be measured on a recurring or nonrecurring basis.

Derivative Financial Instruments

Derivative Financial Instruments

Note 16 — Derivative Financial Instruments

We are exposed to market risk from changes in foreign currency exchange rates, short term interest rates and price fluctuations of certain material commodities such as copper. Foreign currency exchange risks are attributable to sales to foreign customers not denominated in the seller’s functional currency, foreign plant operations, intercompany indebtedness and purchases from foreign suppliers and include exposures to the European Euro, Japanese Yen, Canadian Dollar, and Mexican Peso. The Company regularly enters into derivative contracts with the objective of managing its financial and operational exposure arising from this risk by offsetting gains and losses on the underlying exposures with gains and losses on the financial instruments used to hedge them. We do not enter into derivative financial instruments for speculative or trading purposes. Our hedging relationships are formally documented at the inception of the hedge, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions both at the inception of a hedge and on an ongoing basis. We record the ineffective portion of hedging instruments, if any, to other income (expense) in the consolidated statements of operations.

While W.E.T. continuously monitors the hedging program, derivative positions and hedging strategies and maintains documentation as to the hedging objectives, practices and procedures, W.E.T. has not typically designated its derivatives as hedging instruments for accounting purposes.

In March 2008, W.E.T. entered into a 10 year currency related interest rate swap (“CRS”) having a notional value of €10,000, or $13,203 as of December 31, 2012, in order to offset the interest rate risk associated with a debt financing which was repaid prior our acquisition of W.E.T. Under this agreement W.E.T. receives interest equal to the then six month Euro Interbank Offered Rate (“EUIBOR”), 0.43% at December 31, 2012, plus 1.40% and pays interest equal to the six month EUIBOR when the exchange rate between the European Euro (“EUR”) and the Swiss Franc (“CHF”), which was 1.21 at December 31, 2012, equals or exceeds 1.46 EUR to the CHF or pays interest equal to the six month EURIBOR plus a premium when this exchange rate is less than 1.46. The premium is calculated as [(1.46 — current EUR/CHF rate)/current EUR/CHF rate] x 100. In 2012, W.E.T. entered into offsetting derivative contracts designed to cancel out the payment due under the CRS through the end of the CRS agreement, in 2018.

In July, 2011, the Company entered into a series of interest rate swap contracts and an interest rate cap agreement designated as cash flow hedges in order to hedge the exposure to variable market interest rates on the Company’s senior debt. Gains and losses reported in accumulated other comprehensive income will be reclassified to earnings once the Company’s senior debt is repaid. Information on the interest rate swap contracts is as follows:


Contract Type	Contract Term	Notional Value		Hedged Instruments	Fixed Rate			Variable Rate	Rate Cap
Swap	June 30, 2014	$	8,000	US Term Note		1.27	%	3 month LIBOR		—

New Accounting Pronouncements

Note 17 — New Accounting Pronouncements

Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. In February 2013, the FASB issued ASU No. 2013-02 which amends Topic 220 (Comprehensive Income), and is intended to improve the reporting of reclassifications out of accumulated other comprehensive income into net income. The amendments in ASU No. 2013-02 require an entity to provide information about the effect of amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. ASU No 2013-02 is to be applied prospectively upon adoption and is effective for interim and annual periods beginning after December 15, 2012. While the adoption of ASU No. 2013-02 is not expected to have a material impact on our consolidated financial statements, we expect that it will expand our disclosures related to the reclassification of components of accumulated other comprehensive income to net income.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
