Description of Business: CTS Corporation ("CTS", "we", "our", "us" or the "Company") is a global manufacturer of sensors, connectivity components, and actuators operating as a single reportable business segment. We operate manufacturing facilities located throughout North America, Asia and Europe and service major markets globally.

Principles of Consolidation: The consolidated financial statements include the accounts of CTS and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates: The preparation of financial statements in conformity with the accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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 materially from those estimates.

Cash and Cash Equivalents: All highly liquid investments with maturities of three months or less at the date of purchase are considered to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses: Accounts receivable consists primarily of amounts due from normal business activities. We maintain an allowance for credit losses for estimated uncollectible accounts receivable. Our reserves for estimated credit losses are based upon historical experience, specific customer collection issues, current conditions and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual terms of our receivables and other financial assets. Accounts are written off against the allowance account when they are determined to no longer be collectible.

Concentration of Credit Risk: Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and trade receivables. Our cash and cash equivalents, at times, may exceed federally insured limits. Cash and cash equivalents are deposited primarily in banking institutions with global operations. We have not experienced any losses in such accounts. We believe we are not exposed to any significant credit risk related to cash and cash equivalents.

Trade receivables subject us to the potential for credit risk with major customers. We sell our products to customers principally in the aerospace and defense, industrial, medical, and transportation markets, primarily in North America, Europe, and Asia. We perform ongoing credit evaluations of our customers to minimize credit risk. We do not require collateral. The allowance for credit losses is based on management's estimates of the collectability of its accounts receivable after analyzing historical credit losses, customer concentrations, customer creditworthiness, current economic trends, specific customer collection issues, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual terms of our receivables. Uncollectible trade receivables are charged against the allowance for credit losses when all reasonable efforts to collect the amounts due have been exhausted.

Our net sales to significant customers as a percentage of total net sales were as follows:

	Years Ended December 31,
	2021	2020	2019
Cummins Inc.	15.0%	13.1%	16.1%
Toyota Motor Corporation	12.4%	13.4%	11.6%

We sell parts to these two transportation customers for certain vehicle platforms under purchase agreements that have no volume commitments and are subject to purchase orders issued on a periodic basis.

No other customer accounted for 10% or more of total net sales during these periods.

Inventories: We value our inventories at the lower of the actual cost to purchase or manufacture using the first-in, first-out ("FIFO") method, or net realizable value. We review inventory quantities on hand and record a provision for excess and obsolete inventory based on historical consumption trends as well as forecasts of product demand including related production requirements. Once reserves are established, write-downs of inventory are considered permanent adjustments to the cost basis of inventory. Our reserves contain uncertainties because the calculation requires management to make assumptions and to apply judgment regarding historical experience, market conditions, and product life cycles. Changes in actual demand or market conditions could adversely impact our reserve calculations.

Retirement Plans: We have various defined benefit and defined contribution retirement plans. Our policy is to annually fund the defined benefit pension plans at or above the minimum required by law. We: 1) recognize the funded status of a benefit plan

(measured as the difference between plan assets at fair value and the projected benefit obligation) in our Consolidated Balance Sheets; 2) recognize the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit/cost as a component of other comprehensive earnings; and 3) measure defined benefit plan assets and obligations as of the date of our fiscal year-end.

During 2020, the Company commenced the termination process for its primary U.S. Pension Plan (“U.S. Plan”) and expects to complete the termination process in the first half of 2022. See Note 7, "Retirement Plans" for further information.

Property, Plant and Equipment: Property, plant and equipment is stated at cost, less accumulated depreciation. Depreciation is computed primarily over the estimated useful lives of the various classes of assets using the straight-line method. Useful lives for buildings and improvements range from 10 to 45 years, machinery and equipment from 3 to 15 years, and software from 2 to 15 years. Depreciation on leasehold improvements is computed over the lesser of the lease term or estimated useful lives of the assets. Amounts expended for maintenance and repairs are charged to expense as incurred. Major overhauls that extend the useful lives of existing assets are capitalized. Upon disposition, any related gains or losses are included in operating earnings.

Income Taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, we determine deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe that these assets are more-likely-than-not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

We record uncertain tax positions in accordance with Accounting Standards Codification ("ASC") Topic 740 on the basis of a two-step process in which (1) we determine whether it is more-likely-than-not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

We recognize interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying Consolidated Statements of (Loss) Earnings. Accrued interest and penalties are included in the related tax liability line in the Consolidated Balance Sheets.

Goodwill and Indefinite-lived Intangible Assets: Goodwill represents the excess of the purchase price over the fair values of the net assets acquired in a business combination. In accordance with ASC 350, Intangibles—Goodwill and Other, goodwill is not amortized, but instead is tested for impairment annually or more frequently if circumstances indicate a possible impairment may exist. Absent any interim indicators of impairment, the Company tests for goodwill impairment as of the first day of its fourth fiscal quarter of each year.

Based upon our latest assessment, we determined that our goodwill was not impaired as of October 1, 2021.

In addition to goodwill, we also had an acquired in-process research and development ("IPR&D") intangible asset that was treated as indefinite-lived intangible assets and therefore was not subject to amortization until the completion or abandonment of the associated research and development efforts. In the third quarter of 2020, due to the restructuring actions further outlined in Note 9, we identified a triggering event associated with a specific asset group including IPR&D due to executed restructuring actions. This resulted in the recognition of $2,200 of impairment charges, and a revaluation of associated contingent liabilities totaling $1,900. The net impact of $300 was recorded as restructuring charges in the Consolidated Statements of (Loss) Earnings in 2020.

Other Intangible Assets and Long-lived Assets: We account for long-lived assets (excluding indefinite-lived intangible assets) in accordance with the provisions of ASC 360, Property, Plant, and Equipment. This statement requires that long-lived assets, which includes fixed assets and finite-lived intangible assets, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If an impairment test is warranted, recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the sum of the undiscounted cash flows expected to result from the use and the eventual disposition of the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount in which the carrying amount of the assets exceeds the fair value of the assets. Assets to be

disposed of are reported at the lower of the carrying amount or fair value less costs to sell. In 2020, we recorded a charge of $1,016 due to the impairment of a specific asset group that was recorded in selling, general and administrative expenses in the Consolidated Statements of (Loss) Earnings.

Intangible assets (excluding indefinite-lived intangible assets) consist primarily of technology, customer lists and relationships, patents, and trade names. These assets are recorded at cost and usually amortized on a straight-line basis over their estimated lives. We assess useful lives based on the period over which the asset is expected to contribute to cash flows.

Revenue Recognition: Product revenue is recognized upon the transfer of promised goods to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods net of reserves. We follow the five step model to determine when this transfer has occurred: 1) identify the contract(s) with the customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; 5) recognize revenue when (or as) the entity satisfies a performance obligation. Our revenue reserves contain uncertainties because they require management to make assumptions and to apply judgment to estimate the value of future credits to customers for product returns, price adjustments, and stock rotation adjustments. We base these estimates on the most likely value method considering all reasonably available information, including our historical experience and current expectations, and are reflected in the transaction price when sales are recorded.

Research and Development: Research and development ("R&D") costs include expenditures for search and investigation aimed at discovery of new knowledge to be used to develop new products or processes or to significantly enhance existing products or production processes. R&D costs also include the implementation of new knowledge through design, testing of product alternatives, or construction of prototypes. We expense all R&D costs as incurred, net of customer reimbursements for sales of prototypes and non-recurring engineering charges.

We create prototypes and tools related to R&D projects. A prototype is defined as a constructed product not intended for production resulting in a commercial sale. We also incur engineering costs related to R&D activities. Such costs are incurred to support such activities to improve the reliability, performance and cost-effectiveness of our existing products and to design and develop innovative products that meet customer requirements for new applications. Furthermore, we may engage in activities that develop tooling machinery and equipment for our customers.

We occasionally enter into agreements with our customers whereby we receive a contractual guarantee based on achieving milestones to be reimbursed the costs we incur in the product development process or to construct molds, dies, and other tools that are used to make many of the products we sell. The costs we incur are included in other current assets on the Consolidated Balance Sheets until reimbursement is received from the customer. Reimbursements received from customers are netted against such costs and included in our Consolidated Statements of (Loss) Earnings if the amount received is in excess of the costs that we incur. The following is a summary of amounts to be received from customers as of December 31, 2021 and 2020:

	As of December 31,
	2021		2020
Cost of molds, dies and other tools included in other current assets	$	4,497	$	4,895

Financial Instruments: We use forward contracts to mitigate currency risk related to forecasted foreign currency revenue and costs. These forward contracts are designed as cash flow hedges. At least quarterly, we assess the effectiveness of these hedging relationships based on the total change in their fair value using regression analysis. In addition, we use interest rate swaps to convert a portion of our revolving credit facility's variable rate of interest into a fixed rate. As a result of the use of these derivative instruments, the Company is exposed to the risk that counterparties to derivative contracts will fail to meet their contractual obligations. To mitigate the counterparty credit risk, the Company has a policy of only entering into contracts with carefully selected major financial institutions based upon their credit ratings and other factors and by using netting agreements. Our established policies and procedures for mitigating credit risk on principal transactions include reviewing and establishing limits for credit exposure and continually assessing the creditworthiness of counterparties.


Instrument		Method for determining fair value
Cash, cash equivalents, accounts receivable and accounts payable		Cost, approximates fair value due to the short-term nature of these instruments.
Revolving credit facility		The fair value of long-term debt approximates carrying value and was determined by valuing a similar hypothetical coupon bond and attributing that value to our credit facility.
Interest rate swaps and forward contracts		The fair value of our interest rate swaps and forward contracts are measured using a market approach which uses current industry information.

Debt Issuance Costs: We have debt issuance costs related to our long-term debt that are being amortized using the straight-line method over the term of the debt.

Stock-Based Compensation: We recognize expense related to the fair value of stock-based compensation awards, consisting of restricted stock units ("RSUs"), cash-settled restricted stock units, performance share units ("PSUs"), and stock options, in the Consolidated Statements of (Loss) Earnings.

We estimate the fair value of stock option awards on the date of grant using the Black-Scholes option pricing model. A number of assumptions are used by the Black-Scholes option pricing model to compute the grant date fair value of an award, including expected price volatility, option term, risk-free interest rate, and dividend yield. These assumptions are established at each grant date based upon current information at that time. Expected volatilities are based on historical volatilities of CTS common stock. The expected option term is derived from historical data of exercise behavior. Actual option terms can differ from the expected option terms as a result of different groups of employees exhibiting different exercise behavior. The dividend yield is based on historical dividend payments. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve at the time of grant. The fair value of awards that are ultimately expected to vest is recognized as expense over the requisite service periods of the awards in the Consolidated Statements of (Loss) Earnings.

The grant date fair values of our service-based and performance-based RSUs are the closing price of our common stock on the date of grant. The grant date fair value of our market-based RSUs is determined by using a simulation, or Monte Carlo, approach. Under this approach, stock returns from a comparative group of companies are simulated over the performance period, considering both stock price volatility and the correlation of returns. The simulated results are then used to estimate the future payout based on the performance and payout relationship established by the conditions of the award. The future payout is discounted to the measurement date using the risk-free interest rate.

Both our stock option and RSU awards primarily have a graded vesting schedule. We recognize expense on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in substance, multiple awards. Compensation expense for PSUs is measured by determining the fair value of the award using the closing share price on the grant date and is recognized ratably from the grant date to the vesting date for the number of awards expected to vest. The amount of compensation expense recognized for PSUs is dependent upon a quarterly assessment of the likelihood of achieving the performance conditions and is subject to adjustment based on management's assessment of the Company's performance relative to the target number of shares performance criteria. Forfeitures are recorded as they occur.

(Loss) Earnings Per Share: Basic (loss) earnings per share excludes any dilution and is computed by dividing net (loss) earnings available to common shareholders by the weighted-average number of common shares outstanding for the period.

Diluted earnings per share is calculated by dividing net earnings by the weighted average shares outstanding assuming dilution. Dilutive common shares outstanding is computed using the Treasury Stock Method and reflects the additional shares that would be outstanding if dilutive stock options were exercised, and restricted stock units were settled for common shares during the period. In addition, dilutive shares include any shares issuable related to performance share units for which the performance conditions would have been met as of the end of the period and therefore would be considered contingently issuable. If the common stock equivalents have an anti-dilutive effect, they are excluded from the computation of diluted earnings per share. There was no anti-dilutive impact for the year ended December 31, 2021 as result of a net loss incurred in the period. If there is a net loss for the period, then basic (loss) earnings per share equals diluted (loss) earnings per share.

	Years Ended December 31,
(units)	2021		2020		2019
Antidilutive securities		—		26,140		22,040

Foreign Currencies: The financial statements of our non-U.S. subsidiaries, except the United Kingdom ("U.K.") subsidiary, are remeasured into U.S. dollars using the U.S. dollar as the functional currency with all remeasurement adjustments included in the determination of net (loss) earnings.

Foreign currency (losses) gains recorded in the Consolidated Statements of (Loss) Earnings includes the following:

	Years Ended December 31,
	2021			2020		2019
Foreign currency (losses) gains	$	(3,305	)	$	5,316	$	(1,797	)

The assets and liabilities of our U.K. subsidiary are translated into U.S. dollars at the current exchange rate at period end, with the resulting translation adjustments made directly to the "accumulated other comprehensive loss" component of shareholders' equity. Our Consolidated Statements of (Loss) Earnings accounts are translated at the average rates during the period.

Shipping and Handling: All fees billed to the customer for shipping and handling are classified as a component of net sales. All costs associated with shipping and handling are classified as a component of cost of goods sold or operating expenses, depending on the nature of the underlying purchase.

Sales Taxes: When applicable, we classify sales taxes on a net basis in our consolidated financial statements.

Reclassifications: Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The reclassifications had no impact on previously reported net earnings.

ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting"

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as it relates to our LIBOR indexed instruments. ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022, and an entity may elect to apply ASU 2020-04 for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued.

We amended and restated our credit and underlying interest rate swap agreements effective December 15, 2021. We have elected to continue to apply hedge accounting as we have determined that the hedge remains effective. See Note 13 for further discussion of the credit agreement modification.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, as part of its simplification initiative to reduce the cost and complexity in accounting for income taxes. ASU 2019-12 removes certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of U.S. GAAP. The guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. We adopted this ASU on January 1, 2021 and it did not have a material impact on our financial statements.
