The Company

Note 1 — The Company

Gentherm Incorporated is a global technology and industry leader in the design, development, and manufacturing of innovative thermal management technologies. Unless the context otherwise requires, the terms “Company”, “we”, “us” and “our” used herein refer to Gentherm Incorporated and its consolidated subsidiaries. We operate in locations aligned with our major customers’ product strategies in order to provide locally enhanced design, integration and production capabilities and to identify future climatic comfort product opportunities in both automotive and other markets. We concentrate our research on the development of new technologies that will improve overall product effectiveness and customer satisfaction. We also focus on developing new design applications from our existing technologies to create new products and market opportunities for thermal comfort solutions.

At the present time, the Company has three reportable segments for financial reporting purposes: Climate Controlled Seats (“CCS”), Advanced Technology and W.E.T. (“W.E.T.”).

Climate Controlled Seats

The CCS reporting segment includes products with variable temperature seat climate control systems designed to provide individualized thermal comfort to automobile passengers. It also includes Gentherm’s automotive heated and cooled cup holder and heated and cooled mattress product, although revenues from such products individually are not currently significant to our business. CCS does not include automotive seat comfort products that are part of the W.E.T. segment, despite similarities between some products in each segment. CCS products are primarily sold to automobile and light truck original equipment manufacturers (“OEMs”) or their tier one suppliers. 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 container retention features.

Advanced Technology

Advanced Technology is a research effort engaged in advanced research and development to improve the efficiency of thermoelectric devices and to develop, market, and distribute products based on these new technologies. See the “Research and Development” section of this report for a description of significant internal and government-sponsored research and development programs currently ongoing.

W.E.T.

Based in Odelzhausen, Germany, W.E.T. is a global manufacturer of automotive seat comfort systems, specialized automotive cable systems and other non-automotive product solutions. The automotive seat comfort category includes automotive seat heaters, climate comfort systems (similar to products reported within the CCS segment), steering wheel heater systems and integrated electronic components, such as blowers and electronic control units. The specialized automotive cable systems category includes ready-made wire harnesses and related wiring products. W.E.T.’s customers include passenger car OEMs, commercial vehicle OEMs, and Tier 1 seat manufacturers. Customers of W.E.T.’s other products extend beyond the automotive industry to include companies in the telecommunication, information technology and medical equipment industries.

Gentherm acquired a majority interest in W.E.T. on May 16, 2011. The acquisition was pivotal to our strategy to meet the global requirements of automotive manufacturers throughout the world. From May 16, 2011 until February 22, 2013, W.E.T. was operated as a separate entity, managed by a separate Supervisory Board, due to a legal obligation to ensure that all interactions between Gentherm and W.E.T. were in the best interest of W.E.T.’s non-controlling shareholders. On February 22, 2013, Gentherm successfully registered a Domination and Profit and Loss Transfer Agreement (DPLTA) in Germany which, under German law, enabled us to operate Gentherm and W.E.T. as essentially one company. In October 2013, Gentherm announced the registration of a squeeze-out in Germany and now owns 100 percent of the outstanding shares of W.E.T. and therefore is in full control of W.E.T.

W.E.T. is being treated as an individual segment until we are able to substantially implement our integration plans.

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, 2013, 2012 and 2011, reflect the consolidated financial position and consolidated operating results of the Company. Investments in affiliates in which Gentherm does not have control, but does have the ability to exercise significant influence over operating and financial policies, are accounted for under the equity method. 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”).

Disclosures About Fair Value of Financial Instruments

The carrying amounts of financial instruments comprising cash and cash equivalents, short-term investments and accounts receivable approximate fair value because of the short maturities of these instruments. The carrying amount of the Company’s long-term debt approximates its fair value because interest charged on the loan balance is variable.

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 warranty claims 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,
	2013			2012
Balance at beginning of year	$	8,588		$	8,487
Warranty claims paid or retired		(676	)		(347	)
Expense		2,118			215
Adjustment due to currency translation		278			233
Balance at end of year	$	10,308		$	8,588

Concentration of Credit Risk

Financial assets, 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, 2013, Johnson Controls Inc., Lear Corporation and Magna International Inc. comprised 27%, 24% and 7% respectively, of the Company’s accounts receivable balance. As of December 31, 2012, Johnson Controls Inc., Lear Corporation and Magna International Inc. comprised 26%, 18% and 7% 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 account receivable is outstanding, as well as a customer’s payment history and ability to pay to determine the need for an amount of an allowance for doubtful accounts.

Note 2 — Summary of Significant Accounting Policies and Basis of Presentation (Continued)

Inventory

The Company’s inventory is valued at the lower of cost (the first-in, first-out basis) or market. 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 cost, 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,
	2013			2012
Balance at beginning of year	$	2,185		$	1,127
Expense		779			1,307
Inventory write off		(6	)		(215	)
Adjustment due to currency translation		(25	)		(34	)
Balance at end of year	$	2,933		$	2,185

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

The Company recognized depreciation expense of $14,810, $14,298 and $8,954 for the three years ending December 31, 2013, 2012 and 2011, 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. A roll forward of goodwill from December 31, 2011 to December 31, 2013 is as follows:

December 31, 2011	$	24,245
Exchange rate impact		484
December 31, 2012	$	24,729
Exchange rate impact		1,080
December 31, 2013	$	25,809

The fair value and corresponding useful lives for acquired intangible assets 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

Note 2 — Summary of Significant Accounting Policies and Basis of Presentation (Continued)

Our business strategy largely centers on designing products based upon internally developed and purchased technology. When possible, we protect these technologies with patents. Our policy is to expense all costs associated with the issuance of new patents as incurred. Such costs are classified as research and development expenses in our consolidation statements of income.

Patents purchased as part of a business combination are capitalized based on their fair value. Periodically, we 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.

In 2012, we purchased the rights and ownership of certain intellectual property from Johnson Controls for $7,000. This purchased intellectual property, used in the development and manufacturing of thermoelectric seat comfort technology, has an estimated useful life of seven years. Amortization of the purchased intellectual property will be recognized on a straight-line basis, of which approximately $984 and $285 was amortized during 2013 and 2012, respectively.

A total of $3,340, $2,522 and $1,152 in capitalized patent costs were amortized in 2013, 2012 and 2011, respectively.

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:

2014	$	15,725
2015		14,178
2016		13,011
2017		11,742
2018		9,928
Thereafter		18,681

Gentherm also has $166 of indefinite-lived trademark assets included in other intangible assets on our consolidated balance sheet as of December 31, 2013.

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, 2013 and 2012, respectively.

Annually on December 31^st, 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 and a comparison of market values of a group of comparable companies. 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, 2013 and 2012, respectively.

Note 2 — Summary of Significant Accounting Policies and Basis of Presentation (Continued)

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 probable, 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 $1,691 and $1,878 of reimbursable tooling was capitalized within prepaid expenses and other current assets as of December 31, 2013 and 2012, 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 (“ASC”) 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. Any 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.

Note 2 — Summary of Significant Accounting Policies and Basis of Presentation (Continued)

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 that involve the issuance of common stock to employees, including grants of employee stock options and restricted stock are recognized in the financial statements as compensation expense based upon the fair value on the date of grant. The Company’s stock-based compensation expense and related deferred tax benefit were $3,103 and $419, respectively, for the year ended December 31, 2013, $823 and $301, respectively, for the year ended December 31, 2012, and $1,403 and $427, respectively, for the year ended December 31, 2011.

Share-based payments that are satisfied only by the payment of cash, such as stock appreciation rights, are accounted for as liabilities. The liability is measured at market value of the vested portion of the underlying units. During each period, the change in the liability is recorded as compensation expense or income during periods in which the liability decreases.

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. The Company’s minority interest stems primarily from non-controlling shareholders of W.E.T. As of December 31, 2013, none of these non-controlling shares of W.E.T. remained outstanding and, therefore, Gentherm owned 100 percent of W.E.T. due to the purchase of certain outstanding shares during the year and due to shares tendered, as further described below.

On February 22, 2013, Gentherm’s wholly owned subsidiary, Gentherm Europe, registered a Domination and Profit and Loss Transfer (“DPLTA”) with the German court. This arrangement, somewhat unique to German law, allows Gentherm Europe to take management control of W.E.T. and directly receive W.E.T.’s annual profits and absorb W.E.T.’s annual losses, subject to certain conditions and obligations applicable thereto under German law.

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, any 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) any 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. During 2013, 23,722 shares were tendered under the DPLTA.

On October 31 2013, we announced that a squeeze-out transaction had been registered in Germany. As a result of the squeeze out transaction, Gentherm Europe acquired all shares of W.E.T. that remained outstanding, which totaled 16,147. The shares acquired through the squeeze out transaction represented less than one percent of the total number of outstanding shares. Minority shareholders that transferred shares to Gentherm Europe under part of the squeeze-out transaction were entitled to receive EUR 90.05 per share. Net income attributable to non-controlling interest in our Consolidated Statement of Income represents the portion of net income associated with the minority ownership of W.E.T. shares. Non-controlling interest reported in the Consolidated Balance Sheet and Consolidated Statements of Changes in Shareholders’ Equity for the periods ended December 31, 2013 and 2012 represent the 0.00% and 24.08%, respectively of outstanding voting stock of W.E.T. not acquired in share purchases.

During 2013, certain shareholders that tendered shares under the DPLTA and the squeeze-out transaction have brought appraisal proceedings in the German court seeking higher payment amounts for their shares.

Subsequent Events

We have evaluated subsequent events through March 7, 2014, the date that our consolidated financial statements are issued. No events have occurred that would require adjustment to or disclosure in the consolidated financial statements.

Note 4 — Income Taxes (Continued)

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

Jurisdiction	Amount as of December 31, 2013		Years of Expiration
U.S. Federal income tax	$	9,574		2018 -2019
Foreign	$	4,096		2018

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. 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.

During 2013, we generated an NOL in China associated with the startup activities of a new electronics production facility. This NOL is expected to reverse in 2014 as the location becomes profitable.

Prior to 2013 our NOLs completely offset our current federal tax liability and, therefore, did 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 $2,074 and $171 for 2013 and 2012, respectively, directly to paid-in capital.

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

	Year Ended December 31,
	2013		2012		2011
Income before income taxes:
Domestic	$	6,891	$	3,735	$	12,223

Total deferred income tax expense	$	(47	)	$	789		$	(599	)
Total tax expense	$	11,097		$	8,351		$	4,666

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.

Note 4 — Income Taxes (Continued)

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 $1,300 was 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:

Debt

Note 5 — Debt

In March, 2011, to finance the acquisition of a majority of the outstanding shares of W.E.T. Automotive Systems AG (“W.E.T.”), 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”). Additionally, W.E.T. and W.E.T. Automotive Systems Ltd., a wholly owned Canadian subsidiary, entered into a credit facility with the same syndicate of banks (the “W.E.T. Bank of America credit facility”). 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 a term note (“W.E.T. Term Note”) and a revolving line of credit note (“W.E.T. Revolving Note”). During 2013, an additional draw of $40,400 was made on the Europe Term Note to purchase the remaining shares of W.E.T. held by non-controlling interests.

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”) (0.16% – 0.48% at December 31, 2013) 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 (0.07% at December 31, 2013) plus 0.5%, Bank of America’s prime rate (3.25% at December 31, 2013), or a one month Eurocurrency rate plus 1.0%. The Applicable Rate for the current period was 2.25% for Eurocurrency Rate Loans and 1.25% 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, 2013 and 2012 and $29,550 and €20,000 were available under each note, respectively. Gentherm also has an outstanding Letter of Credit of $450 as of December 31, 2013 and 2012.

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

During 2013, we borrowed €4,000, or $5,561, from the German Investment Corporation, a subsidiary of KfW banking group, a German government-owned development bank (“DEG Loan”), to fund a plant expansion project in China. The DEG Loan is unsecured, has a fixed interest rate of 4.25% and is subject to semi-annual principal payments beginning March, 2015 and ending September 2019. A minimum Debt-to-Equity Ratio, Current Ratio and Debt Service Coverage Ratio, based on the financial statements of our wholly-owned subsidiary W.E.T. Automotive Systems (China) Limited, is required in order to remain in compliance with the terms of the DEG loan.

Note 5 — Debt (Continued)

A new lease agreement for an enterprise resource planning system commenced June 2013, and will end May, 2015. Under the terms of the lease, the Company must maintain certain financial covenants. Ownership of the system will be transferred to the Company at the end of the agreement. This new capital lease was treated as a non-cash transaction for purposes of the cash flow statement.

As of December 31, 2013, we were in compliance with all terms as outlined in the credit agreements for the US Bank of America credit facility, the W.E.T. Bank of America credit facility and the DEG Loan. The following table summarizes the Company’s debt at December 31, 2013.

In March 2011, the Company 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.

Holders of the Series C Convertible Preferred Stock were entitled to receive, out of funds legally available there from, dividends payable in cash (if permitted under the US Bank of America credit facility), our Common Stock (if certain equity conditions were 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 were cumulative from the date of initial issuance.

The Series C Convertible Preferred Stock was to be redeemed in nine equal quarterly installments that began on September 1, 2011 and ended 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.

Holders of the Series C Convertible Preferred Stock could have converted 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 would 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 US Bank of America credit facility prohibits payment of the make-whole amount, we would 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.

During 2013, holders of the Series C Convertible Preferred Stock elected to convert their shares into shares of common stock at the conversion price of $15.83 per share. The Company issued approximately 954,000 shares of common stock related to the conversion of Series C Convertible Preferred Stock.

The following table discloses the total Series C Convertible Preferred Stock installments paid in cash during the twelve month period ended December 31, 2013. No portions of the installments were paid in shares of Gentherm’s common stock.

Accounting for Stock Based Compensation

Note 7 — Accounting for Stock Based Compensation

On May 16, 2013, the Compensation Committee of the Company’s Board of Directors approved the Gentherm Incorporated 2013 Equity Incentive Plan (the “2013 Plan”), covering 3,500,000 shares of our common stock. The 2013 Plan permits the granting of various awards including stock options (including both nonqualified options and incentive options), stock appreciation rights (“SARs”), restricted stock and restricted stock units, performance shares and certain other awards to key employees, outside directors and consultants and advisors of the Company. All shares of our common stock that remained available for issuance under the Amended and Restated 2006 Stock Incentive Plan (the “2006 Plan”) and the Gentherm Incorporated 2011 Equity Incentive Plan (the “2011 Plan”), totaling 2,315,578 shares in the aggregate, were reduced to zero; however certain options under the 2011 and 2006 Plans, as well as certain options under the 1997 Stock Incentive Plan, which expired in 2007, are still outstanding. As of December 31, 2013 the Company had an aggregate of 2,720,332 shares of common stock available to issue under the 2013 Plan.

Note 7 — Accounting for Stock Based Compensation (Continued)

All 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, for example, granted under such 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, restricted shares and SARs are generally granted with requisite service periods typically ranging between three to five years for employees and one year for directors. Stock based compensation award vesting may be accelerated at the discretion of the Board of Directors.

Total unrecognized compensation cost related to nonvested options, restricted stock and SARs outstanding under all of the Company’s equity plans was $10,613 and $3,902 as of December 31, 2013 and 2012, respectively. That cost is expected to be recognized over a weighted average period of two years. Compensation expense for the year ended December 31, 2013, 2012 and 2011 was $3,103, $823 and $1,403, respectively.

Stock Options

The following table summarizes stock option activity during the three year period ended December 31, 2013:

Exercisable at December 31, 2013		1,055,176		$	12.21		4.58	$	19,314

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:

	2013	2012	2011
Expected volatility	34%	47%	49-55%
Weighted average expected volatility	34%	47%	55%
Expected lives	3 yrs.	3 yrs.	3 - 5 yrs.
Risk-free interest rate	0.57-0.65%	0.43%	0.37-0.94%
Expected dividend yield	none	none	none

Note 7 — Accounting for Stock Based Compensation (Continued)

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. The Company uses historical exercise data and several other factors in developing an assumption for the expected lives of stock options, 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, the prohibition to issue dividend under terms of the US Bank of America credit facility 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 weighted-average grant-date fair value of options granted during the year ended December 31, 2013, 2012 and 2011 was $4.71, $4.13 and $4.78, respectively. The total intrinsic value of options exercised during the year ended December 31, 2013, 2012 and 2011 was $8,301, $1,663 and $4,876, respectively.

Earnings Per Share

Note 8 — 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 income:

	Year ended December 31,
	2013		2012		2011
Weighted average number of shares for calculation of basic EPS – Common Stock		33,652,646		28,352,864		22,605,518

Shareholder Rights Plan

Note 10 — 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.

Executive Nonqualified Defined Benefit Plan

Executive Nonqualified Defined Benefit Plan

Note 12 — 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:

	2013			2012
Change in projected benefit obligation:
Benefit obligation at beginning of year	$	1,633		$	1,142
Service cost		355			317
Interest cost		53			45
Actuarial loss		(193	)		129
Net periodic benefit cost		215			491
Benefit obligation at end of year	$	1,848		$	1,633

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 income 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 income based on the average future service life of the Plan. A discount rate assumption of 4.25%, 3.25% and 4.0% was used to determine the benefit obligation and the net periodic service cost for years ended December 31, 2013, 2012 and 2011, respectively.

Note 12 — Executive Nonqualified Defined Benefit Plan (Continued)

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 $1,962 and $1,466 as of December 31, 2013 and 2012, 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:

	2013			2012
Change in projected benefit obligation:
Benefit obligation at beginning of year	$	5,392		$	4,250
Service cost		—			199
Interest cost		180			195
Paid pension distributions		(291	)		(277	)
Actuarial (gains)/losses		43			912
Past service cost		445			—
Exchange rate impact		250			113
Benefit obligation at end of year	$	6,019		$	5,392

The following table sets forth the fair value of the plan assets for the periods ending December 31, 2013 and 2012:

	2013			2012
Change in plan assets:
Plan assets at beginning of year	$	1,548		$	1,098
Actual return on plan assets		59			41
Net contributions		664			386
Actuarial loss		(24	)		(11	)
Exchange rate impact		93			34
Plan assets at end of year	$	2,340		$	1,548

The W.E.T. defined benefit plan is underfunded by $3,679 and $3,844 as of December 31, 2013 and 2012, 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 statements of income. The following table describes the actuarial assumptions used to determine the benefit obligation and the net periodic service cost:

	2013
Discount rate		3.46	%
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.

Note 12 — Executive Nonqualified Defined Benefit Plan (Continued)

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

Year
2014	$	302
2015		303
2016		302
2017		302
2018		300
2019 - 2023		1,473
Total	$	2,982

Gentherm has adopted a 401(k) plan to provide all eligible employees a means to accumulate retirement savings on a tax-advantaged basis, and eligible executive officers can participate in this plan on the same basis as other participants. Participants may defer specified portions of their compensation and (1) we match 50% percent of employee contributions up to a contribution equal to 2% percent of the employee’s compensation and (2) we may, but are not required to, make additional discretionary contributions. The Compensation Committee has not made any discretionary contribution to the 401(k) Plan since its inception. Gentherm made $191, $161 and $136 in matching contributions to the 401(k) plan in 2013, 2012 and 2011, respectively.

Fair Value Measurement

Dec. 31, 2013

Fair Value Measurement

Note 13 — 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, pension liabilities and pension plan assets, the Company has no financial assets and liabilities that are carried at fair value at December 31, 2013 and 2012. 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 5 for a description of Company’s debt and corresponding rates of interest. See Note 12 regarding the fair value of pension liabilities and pension plan assets. See Note 15 regarding the fair value of derivative instruments and hedging activities.

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, 2013 and 2012, the Company did not realize any changes to the fair value of these assets due to events that negatively impacted their recoverability.

Derivative Financial Instruments

Derivative Financial Instruments

Note 14 — Derivative Financial Instruments

We are exposed to market risk from changes in foreign currency exchange rates and short term interest rates. Market risks for changes in interest rates relate primarily to our debt obligations under our Bank of America credit facilities. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in the location’s functional currency, foreign plant operations, intercompany indebtedness and include exposures to the European Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, Ukraine Hryvnia and Korean Won. 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 to be designated for hedge accounting treatment. We record the ineffective portion of hedging instruments, if any, to other income (expense) in the consolidated condensed statements of income. Though we continuously monitor the hedging program, derivative positions and hedging strategies, foreign currency forward exchange agreements have not always been designated 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 $13,779 as of December 31, 2013, 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 (“EURIBOR”), 0.39% at December 31, 2013, plus 1.40% and pays interest equal to the six month EURIBOR when the exchange rate between the European Euro (“EUR”) and the Swiss Franc (“CHF”), which was 1.23 at December 31, 2013, 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 2011, W.E.T. brought a lawsuit against UniCredit Bank AG (“UniCredit”), a past financial advisor, stemming from the recommendation to invest in the aforementioned CRS. On March 25, 2013, the Munich District Court in Munich, Germany ruled in favor of W.E.T., asserting that UniCredit violated its duty to properly advise W.E.T. with respect to the initial negative market value for the CRS and UniCredit’s inherent conflict of interest in recommending that W.E.T. invest in CRS. The Munich District Court ruled that UniCredit must (1) pay €144 to W.E.T. and (2) bear the costs of all future obligations under the CRS, which were €8,584 or $11,828 as of December 31, 2013, plus additional accrued liabilities for past due payments under the CRS of approximately €5,380, or $7,413 as of December 31, 2013. UniCredit has appealed the decision and an extension has been granted. As a result, the Company cannot be certain that any portion of the award by the Munich District Court will be realized by W.E.T. See the derivatives table below for information about our future obligations under the CRS as of December 31, 2013 and 2012, respectively. The Company has entered into offsetting derivative contracts designed to cancel out the market risk of payments due under the CRS through the end of the CRS agreement, in 2018.

In July 2011, the Company entered into two interest rate swap contracts with separate financial institutions and an interest rate cap agreement in order to hedge the exposure to variable market interest rates on the Company’s Bank of America credit facilities. The interest rate swap contracts qualified for and are designated as cash flow hedges. Swap gains and losses are reported in accumulated other comprehensive income and will be reclassified to earnings once the Company’s Bank of America credit facilities are repaid. Cap gains and losses are reported in foreign currency gains and losses on the consolidated statement of income. Information on the interest rate swap contracts is as follows:

Tax Regulation. In October 2013, the IRS issued final regulations to clarify and expand guidance relating to amounts paid to acquire, produce or improve the basis of property. The final regulations also provide guidance on the tax accounting for and retirement of depreciable property in the United States. The final regulation affects all taxpayers that acquire, produce, or improve tangible property. The Company has determined, however, that it does not have a material impact to our consolidated financial statements.
