Notes to Condensed Consolidated Financial Statements

October 1, 2017

(Unaudited)

Note 1 – Nature of Operations

Headquartered in Southfield, Michigan, the principal business of Superior Industries International, Inc. (referred to herein as the “company” or “we,” “us” and “our”) is the design and manufacture of aluminum wheels for sale to original equipment manufacturers (“OEMs”). We are one of the largest suppliers of cast aluminum wheels to the world’s leading automobile and light truck manufacturers, with manufacturing operations in North America and Europe. Customers in North America and Europe represent the principal market for our products.

Our largest customers, Ford Motor Company (“Ford”), General Motors Company (“GM”) and Toyota Motor Company (“Toyota”) each accounted for more than 10 percent of our consolidated sales in the first nine months of 2017 and together represented approximately 56 percent of our trade sales during the first nine months of 2017. Additionally, Nissan Motor Co., Ltd. (“Nissan”) and Fiat Chrysler Automotive N.V. (“FCA”) individually accounted for 6 percent and 4 percent, respectively, of our consolidated sales during the first nine months of 2017 and together with Ford, GM and Toyota represented approximately 66 percent of our trade sales during the first nine months of 2017. We also manufacture aluminum wheels for BMW, Mazda, Subaru, Tesla and Volkswagen. Additionally, the acquisition of Uniwheels AG (“Uniwheels”) on May 30, 2017 diversifies our OEM customer base to include Audi AG (“Audi”), Mercedes-Benz, and other European customers and also provides a diversified base of new aftermarket customers. The loss of all or a substantial portion of our sales to Ford, GM or Toyota would have a significant adverse impact on our operating results and financial condition. This risk is partially mitigated by our long-term relationships with these OEM customers and our supply arrangements, which are generally for multi-year periods.

Demand for automobiles and light trucks (including SUVs and crossover vehicles) in the North American and European markets is subject to many unpredictable factors such as changes in the general economy, gasoline prices, consumer credit availability and interest rates. Demand for aluminum wheels can be further affected by other factors, including pricing and performance compared to competitive materials such as steel. Additionally, the demand for our products is influenced by shifts of market share between vehicle manufacturers and the specific market penetration of individual vehicle platforms being sold by our customers.

Note 2 – Presentation of Condensed Consolidated Financial Statements

During interim periods, we follow the accounting policies set forth in our Annual Report on Form 10-K for the fiscal year ended December 25, 2016 (the “2016 Annual Report on Form 10-K”) and apply appropriate interim financial reporting standards for a fair statement of our operating results and financial position in conformity with accounting principles generally accepted in the United States of America, as codified by the Financial Accounting Standards Board (“FASB”) in the Accounting Standards Codification (“ASC”) (referred to herein as “U.S. GAAP”), as indicated below. For convenience of presentation, the 2016 fiscal year is referred to as December 31, but actually reflects our financial position and results of operations for the period described below. Users of financial information produced for interim periods in 2017 are encouraged to read this Quarterly Report on Form 10-Q in conjunction with our consolidated financial statements and notes thereto filed with the Securities and Exchange Commission (“SEC”) in our 2016 Annual Report on Form 10-K.

In the past, Superior has used a 4-4-5 convention for our fiscal quarters, which are thirteen week periods (referred to as quarters) ending on the last Sunday of each calendar quarter. Each fiscal year for the last three years has had 52 weeks. Fiscal 2017 is a 53 week fiscal year and as a consequence one quarter, typically the fourth quarter, has fourteen weeks. Uniwheels, our European operations, is based on a calendar year end. Consequently, to more closely align our third quarter end dates, we have adjusted the quarter-end date of our North American operations to October 1, 2017 from September 24, 2017, resulting in

Table of Contents

a fiscal quarter consisting of fourteen weeks (referred to either as the quarter or three months ended October 1, 2017).    This modification to the third quarter timing aligns the close of the third quarter of the North American Operations within one day of the close of the third quarter of the European operations, which ended on September 30, 2017. Therefore, in the third quarter there is a slight difference in timing of the quarter close of our two operations that is deemed to be insignificant. The year ends of our North America and European operations will align in the fourth quarter ending on December 31, 2017. Starting in 2018 both our North American and European operations will be on a calendar year end with each month ending on the last day of the month.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the SEC’s requirements for quarterly reports on Form 10-Q and U.S. GAAP and, in our opinion, contain all adjustments, of a normal and recurring nature, which are necessary for a fair statement of (i) the condensed consolidated statements of operations for the three and nine month periods ended October 1, 2017, (ii) the condensed consolidated statements of comprehensive income for the three and nine month periods ended October 1, 2017, (iii) the condensed consolidated balance sheets at October 1, 2017 and December 31, 2016, (iv) the condensed consolidated statements of cash flows for the nine month periods ended October 1, 2017 and September 25, 2016, and (v) the condensed consolidated statement of shareholders’ equity for the nine month period ended October 1, 2017. However, the accompanying unaudited condensed consolidated financial statements do not include all information and notes required by U.S. GAAP. The condensed consolidated balance sheet as of December 31, 2016, included in this report, was derived from our 2016 audited financial statements, but does not include all disclosures required by U.S. GAAP.

Interim financial reporting standards require us to make estimates that are based on assumptions regarding the outcome of future events and circumstances not known at that time, including the use of estimated effective tax rates. Inevitably, some assumptions will not materialize, unanticipated events or circumstances may occur which vary from those estimates and such variations may significantly affect our future results. Additionally, interim results may not be indicative of our results for future interim periods or our annual results.

New Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) “Revenue from Contracts with Customers.” This update outlines a single, comprehensive model for accounting for revenue from contracts with customers. We plan to adopt this update on January 1, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). We anticipate adopting the standard using the modified retrospective method. There may be differences in timing of revenue recognition under the new standard compared to recognition under ASC 605 - Revenue Recognition. We have completed an initial assessment of our North America operations and are currently reviewing our Europe operations that we acquired in the second quarter.

In February of 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires an entity to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires modified retrospective adoption, with early adoption permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

In August 2016, the FASB issued an ASU entitled “Statement of Cash Flows (Topic 740): Classification of Certain Cash Receipts and Cash Payments.” The objective of the ASU is to address the diversity in practice in the presentation of certain cash receipts and cash payments in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our statement of cash flows.

Table of Contents

In October 2016, the FASB issued an ASU entitled “Income Taxes (Topic 230): Intra-Entity Transfers of Assets Other than Inventory.” The objective of the ASU is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

In November 2016, the FASB issued an ASU entitled “Statement of Cash Flows (Topic 230): Restricted Cash.” The objective of the ASU is to address the diversity in practice that exists in the classification and presentation of changes in restricted cash on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our statement of cash flows.

In January 2017, the FASB issued an ASU entitled “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The objective of the ASU is to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

In January 2017, the FASB issued an ASU entitled “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The objective of the ASU is to add guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

In March 2017, the FASB issued an ASU entitled “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The objective of the ASU is to improve the reporting of net benefit cost in the financial statements. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

In July 2017, the FASB issued an ASU entitled “(Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception”. The objective of this ASU is to reduce the complexity in accounting for certain financial instruments with down round features. When determining whether certain financial instruments should be classified as debt or equity instruments, a down round feature would no longer preclude equity classification when assessing whether the instrument is indexed to an entity’s own stock. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. Early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

In August 2017, the FASB issued an ASU entitled “Derivatives and Hedging (Topic 815).” The objective of this standard is to better align financial reporting with risk management activities, provide a more faithful representation of hedging activities and reduce complexity and costs associated with hedging. This ASU removes the requirement to recognize hedge ineffectiveness in income prior to settlement, allows documentation of hedge effectiveness at inception to be completed by quarter-end, allows qualitative rather than quantitative assessment of effectiveness (subsequent to initial quantitative assessment), allows critical terms match for cash flow hedges of a group of forecasted transactions if derivatives mature within the same month as transactions, permits use of the “back up” long haul method for hedges initially designated using the short cut method and permits cash flow hedging of a component of purchases and sales of non-financial assets (i.e., commodity price excluding transportation) resulting in higher hedge effectiveness. The ASU also permits fair value hedging of the benchmark interest rate

component of interest rate risk as well as partial term hedging, allows partial term fair value hedges of interest rate risk, permits cash flow hedging of interest rate risk for a contractually specified rate rather than a benchmark rate and permits exclusion of cross currency basis spread in determining effectiveness. This ASU is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We are evaluating the impact this guidance will have on our financial position and statement of operations.

Note 3 – Acquisition

On March 23, 2017, Superior announced that it had entered into various agreements to commence a tender offer to acquire 100 percent of the outstanding equity interests of Uniwheels (the “Acquisition”) through a newly-formed, wholly-owned subsidiary (the “Acquisition Sub”). The Acquisition will be effected through a multi-step process as more fully described below.

In the first step of the Acquisition, on March 23, 2017, Superior obtained a commitment from the owner of approximately 61 percent of the outstanding stock of Uniwheels, Uniwheels Holding (Malta) Ltd. (the “Significant Holder”), evidenced by an irrevocable undertaking agreement (the “Undertaking Agreement”) to tender such stock in the second step of the Acquisition. In connection with the Undertaking Agreement, on March 23, 2017: (i) Superior entered into a business combination agreement with Uniwheels pursuant to which, subject to the provisions of the German Stock Corporation Act, Uniwheels and its subsidiaries undertook to, among other things, cooperate with the financing of the Acquisition; and (ii) Superior and the Significant Holder entered into a guarantee and indemnification agreement pursuant to which Superior will hold the Significant Holder harmless for claims that may arise relating to its involvement with Uniwheels. As Uniwheels is a company listed on the Warsaw Stock Exchange, the Acquisition was required to be carried out in accordance with the Polish Act of 29 July 2005 on Public Offerings and the Conditions for Introducing Financial Instruments to Organized Trading and Public Companies (the “Public Offering Act”).

Following the publication of a formal tender offer document by Superior, as required by the Public Offering Act, Superior commenced the acceptance period for the tender offer (the “Tender Offer”) on April 12, 2017, pursuant to which, Superior offered to purchase all (but not less than 75 percent) of the outstanding stock of Uniwheels and, upon the consummation of the Tender Offer, agreed to purchase the stock of the Significant Holder along with all other stock of Uniwheels tendered pursuant to the Tender Offer. On May 30, 2017, Superior acquired 92.3 percent of the outstanding stock of Uniwheels for approximately $703.0 million (based on an exchange rate of 1.00 Dollar = 3.74193 Polish Zloty). We refer to this acquisition as the “First Step Acquisition.”

Under the terms of the Tender Offer:

On June 30, 2017, the company announced that it had commenced the delisting and associated tender process for the remaining outstanding shares of Uniwheels. As of July 31, 2017, 153,251 additional shares (representing 1.2 percent of Uniwheels shares) were tendered at Polish Zloty 247.87 per share. We refer to this acquisition as the “Second Step Acquisition.” The aggregate equity purchase price of the Acquisition (assuming the remaining 6.5 percent of Uniwheels’ stock is acquired for cash consideration of Polish Zloty 247.87 per share, the price paid to Uniwheels’ shareholders in the Tender Offer, and an exchange rate of 1.00 Dollar = 3.74193 Polish Zloty) will be approximately $778.0 million. We entered into foreign currency hedges prior to the closing of the First Step Acquisition intended to reduce currency risk associated with the settlement of the Tender Offer (the “Hedging Transactions”). The net benefit of such Hedging Transactions to Superior reduced the total anticipated purchase price of the Acquisition to $766.2 million.

Table of Contents

The company’s condensed consolidated financial statements for the three and nine month periods ended October 1, 2017 and September 25, 2016 include Uniwheels results of operations subsequent to May 30, 2017 (please see Note 7, “Business Segments” for the segment results included within the condensed consolidated financial statements for the three and nine month periods ended October 1, 2017 and September 25, 2016, which include Uniwheels results of operations subsequent to May 30, 2017). The company’s condensed consolidated financial statements reflect the purchase accounting adjustments in accordance with ASC 805 “Business Combinations”, whereby the purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values on the acquisition date.

During the second quarter of 2017, the company determined a preliminary valuation of the identifiable assets acquired and the liabilities assumed. The following is the allocation of the purchase price:

The above goodwill represents future economic benefits expected to be recognized from the company’s expansion into the European wheel market, as well as expected future synergies and operating efficiencies from combining operations with Uniwheels. Acquisition goodwill of $321.7 million (initial balance of $306.2 million, increased for post-acquisition translation adjustments) has been allocated to the European segment.

The following unaudited combined pro forma information is for informational purposes only. The pro forma information is not necessarily indicative of what the combined company’s results actually would have been had the Acquisition been completed as of the beginning of the periods as indicated. In addition, the unaudited pro forma information does not purport to project the future results of the combined company.

Note 4 – Restructuring

During 2014, we completed a review of initiatives to reduce costs and enhance our competitive position. Based on this review, we committed to a plan to close operations at our Rogers, Arkansas facility, which was completed during the fourth quarter of 2014. The action was undertaken in order to reduce costs and enhance our global competitive position. During the fourth quarter of 2016, we sold the Rogers facility for total proceeds of $4.3 million, resulting in a $1.4 million gain on sale, which is recorded as a reduction to selling, general and administrative expense in the consolidated income statements.

The total cost incurred as a result of the Rogers facility closure was $16.0 million, of which $0.1 million and $0.2 million was recognized for the nine month periods ended October 1, 2017 and September 25, 2016, respectively. The following table summarizes the Rogers, Arkansas plant closure costs and classification in the consolidated income statement for the period ended October 1, 2017:

Note 5 – Fair Value Measurements

The company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis, while other assets and liabilities are measured at fair value on a nonrecurring basis, such as when we have an asset impairment. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The carrying amounts for cash and cash equivalents, investments in certificates of deposit, accounts receivable, accounts payable and accrued expenses approximate their fair values due to the short period of time until maturity.

12

Table of Contents

Cash and Cash Equivalents

Included in cash and cash equivalents are highly liquid investments that are readily convertible to known amounts of cash, and which are subject to an insignificant risk of change in value due to interest rates, quoted price or penalty on withdrawal. A debt security is classified as a cash equivalent if it meets these criteria and if it has a remaining time to maturity of three months or less from the date of acquisition. Amounts on deposit and available upon demand, or negotiated to provide for daily liquidity without penalty, are classified as cash and cash equivalents. Time deposits, certificates of deposit and money market accounts that meet the above criteria are reported at par value on our balance sheet and are excluded from the table below.

Derivative Financial Instruments

Our derivatives are over-the-counter customized derivative transactions and are not exchange traded. We estimate the fair value of these instruments using industry-standard valuation models such as a discounted cash flow. These models project future cash flows and discount the future amounts to a present value using market-based expectations for interest rates, foreign exchange rates, commodity prices and the contractual terms of the derivative instruments. The discount rate used is the relevant interbank deposit rate (e.g., LIBOR) plus an adjustment for non-performance risk. In certain cases, market data may not be available, and we may use broker quotes and models (e.g., Black-Scholes) to determine fair value. This includes situations where there is lack of liquidity for a particular currency or commodity or when the instrument is longer dated. The fair value measurements of the redeemable preferred shares embedded derivatives are based upon Level 3 unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the liability – refer to “Note 6, Financial Instruments.”

Cash Surrender Value

The cash surrender value of the life insurance policies is the sum of money the insurance company will pay to the company in the event the policy is voluntarily terminated before its maturity or the insured event occurs. Over the term of the life insurance contracts, the cash surrender value changes as a result of premium payments and investment income offset by investment losses, charges and miscellaneous fees. The amount of the asset recorded for the investment in the life insurance contracts is equal to the cash surrender value which is the amount that will be realized under the contract as of the balance sheet date if the insured event occurs.

The following table categorizes items measured at fair value at October 1, 2017:

The following table categorizes items measured at fair value at December 31, 2016:

Derivative Instruments and Hedging Activities

We use derivatives to partially offset our business exposure to foreign currency risk. We may enter into forward contracts, option contracts, swaps, collars or other derivative instruments to offset some of the risk on expected future cash flows and on certain existing assets and liabilities. However, we may choose not to hedge certain exposures for a variety of reasons including, but not limited to, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange rates.

To help protect gross margins from fluctuations in foreign currency exchange rates, certain of our subsidiaries whose functional currency is the U.S. dollar hedge a portion of forecasted foreign currency costs. Generally, we may hedge portions of our forecasted foreign currency exposure associated with costs, typically for up to 48 months.

14

Table of Contents

We record all derivatives in the condensed consolidated balance sheets at fair value. Our accounting treatment for these instruments is based on the hedge designation. The effective portions of cash flow hedges are recorded in Accumulated Other Comprehensive Income (“AOCI”) until the hedged item is recognized in earnings. The ineffective portions of cash flow hedges are recorded in cost of sales. Derivatives that are not designated as hedging instruments are adjusted to fair value through earnings in the financial statement line item to which the derivative relates. All derivatives were designated as hedging instruments at December 31, 2016. At October 1, 2017, the company held derivatives that were designated as hedging instruments as well as derivatives that did not qualify for designation as hedging instruments as discussed below.

Deferred gains and losses associated with cash flow hedges of foreign currency costs are recognized as a component of cost of sales in the same period as the related cost is recognized. Our foreign currency transactions hedged with cash flow hedges as of October 1, 2017, are expected to occur within 1 month to 48 months.

Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two-month time period. Deferred gains and losses in AOCI associated with such derivative instruments are reclassified immediately into other expense. Any subsequent changes in fair value of such derivative instruments are reflected in other expense unless they are re-designated as hedges of other transactions.

Currency option derivative contracts not designated as hedging instruments consist principally of certain option contracts to purchase Polish Zloty and the Euro related to the acquisition of Uniwheels and a cross currency swap. See Note 3, “Acquisition.”

Redeemable Preferred Stock Embedded Derivative

We have determined that the conversion option embedded in Series A redeemable preferred stock is required to be accounted for separately from the Series A redeemable preferred stock as a derivative liability. Separation of the conversion option as a derivative liability is required because its economic characteristics are considered more akin to an equity instrument and therefore the conversion option is not considered to be clearly and closely related to the economic characteristics of the redeemable preferred stock. This is because the economic characteristics of the redeemable preferred stock are considered more akin to a debt instrument due to the fact that the shares are redeemable at the holder’s option, the redemption value is significantly greater than the face amount, the shares carry a fixed mandatory dividend, the stock price necessary to make conversion more attractive than redemption ($56.324) is significantly greater than the price at the date of issuance ($19.05), all of which lead to the conclusion that redemption is more likely than conversion. For additional information on the redeemable preferred stock, see Note 13, “Redeemable Preferred Shares” in Notes to Condensed Consolidated Financial Statements.

We have also determined that the early redemption option upon the occurrence of a redemption event (e.g. change of control, etc.) must also be bifurcated and accounted for separately from the redeemable preferred stock at fair value, because the debt host contract involves a substantial discount (face of $150.0 million as compared to the redemption value of $300 million) and exercise of the early redemption option would accelerate the holder’s option to redeem the shares.

Accordingly, we have recorded an embedded derivative liability representing the combined fair value of the right of holders to receive common stock upon conversion of Series A redeemable preferred stock at any time (the “conversion option”) and the right of the holders to exercise their early redemption option upon the occurrence of a redemption event (the “early redemption option”). The embedded derivative liability is adjusted to reflect fair value at each period end with changes in fair value recorded in the “Change in fair value of redeemable preferred stock embedded derivative liability” financial statement line item of the company’s consolidated statements of operations (refer to “Note 13, Redeemable Preferred Shares”).

A binomial option pricing model is used to estimate the fair value of the conversion and early redemption options embedded in the redeemable preferred stock. The binomial model utilizes a “decision tree” whereby future movement in the company’s common stock price is estimated based on the volatility factor. The binomial options pricing model requires the development and use of assumptions. These assumptions include estimated volatility of the value of our common stock, assumed possible conversion or early redemption dates, an appropriate risk-free interest rate, risky bond rate and dividend yield.

15

Table of Contents

The expected volatility of the company’s equity is estimated based on the historical volatility of our common stock. The assumed base case term used in the valuation model is the period remaining until May 22, 2024 (the earliest date at which the holder may exercise its unconditional redemption option). A number of other scenarios incorporated earlier redemption dates to address the possibility of early redemption upon the occurrence of a redemption event. The risk-free interest rate is based on the yield on the U.S. Treasury zero coupon yield curve with a remaining term equal to the expected term of the conversion and early redemption options. The significant assumptions utilized in the company’s valuation of the embedded derivatives at October 1, 2017 are as follows: valuation scenario terms between 4.25 and 6.64 years, volatility of 32.0%, risk-free rate of 1.81%-2.12% related to the respective assumed terms, a risky bond rate of 19.1% and a dividend yield of 2.2%.

Based on the foregoing assumptions the fair value of the redeemable preferred stock embedded derivative liability at October 1, 2017 is $6.7 million and the change in fair value of redeemable preferred stock embedded derivative liability during the quarter was $4.1 million mainly due to the decline in our stock price from $19.05 (at date of issuance) to $16.65 (at October 1, 2017) and the reduction in the remaining term of the options used in the valuation scenarios due to the months elapsed since issuance.

The following tables display the fair value of derivatives by balance sheet line item at October 1, 2017 and December 31, 2016:

The following table summarizes the notional amount and estimated fair value of our derivative financial instruments:

Notional amounts are presented on a gross basis. The notional amounts of the derivative financial instruments do not represent amounts exchanged by the parties and, therefore, are not a direct measure of our exposure to the financial risks described above. The amounts exchanged are calculated by reference to the notional amounts and by other terms of the derivatives, such as interest rates, foreign currency exchange rates or commodity volumes and prices.

The following table provides the impact of derivative instruments designated as cash flow hedges on our statement of operations:

Note 7 – Business Segments

Superior groups its operating segments into reportable segments in which sales and manufacturing efforts are focused. The products, manufacturing, and procurement are similar throughout the company’s operations. Each operating segment has discrete financial information evaluated regularly by the company’s Chief Operating Decision Maker (“CODM”) in determining resource allocation and assessing performance. As a result of the Uniwheels acquisition, the company realigned its executive management structure which changed the information used by our CODM to assess performance and allocate resources. Due to different economic circumstances and customer base in the company’s operations and in conformity with ASC Topic 280, “Segment Reporting,” the company reports the results of its business in two reportable segments: North America and Europe.

Note 8 – Short-Term Investments

Certificates of deposit and fixed deposits whose original maturity is greater than three months and is one year or less are classified as short-term investments and certificates of deposit and fixed deposits whose maturity is greater than one year at the balance sheet date are classified as non-current assets in our condensed consolidated balance sheets. The purchase of any certificates of deposit or fixed deposits that are classified as short-term investments or non-current assets appear in the investing section of our condensed consolidated statements of cash flows.

Restricted Deposits

We purchase certificates of deposit that mature within twelve months and are used to secure or collateralize letters of credit securing our workers’ compensation obligations. At each of October 1, 2017 and December 31, 2016, certificates of deposit totaling $0.8 million were restricted in use and were classified as short-term investments on our condensed consolidated balance sheets.

Table of Contents

Service wheel and supplies inventory included in other non-current assets in the condensed consolidated balance sheets totaled $8.5 million and $6.5 million at October 1, 2017 and December 31, 2016, respectively. Included in raw materials were operating supplies and spare parts totaling $13.6 million and $10.3 million on October 1, 2017 and December 31, 2016, respectively. The significant increase in the current year inventory is attributable to the acquired European operations.

Depreciation expense was $36.7 million and $25.9 million for the nine months ended October 1, 2017 and September 25, 2016, respectively. The significant increase in balances is attributable to property, plant, and equipment related to our acquired European operations.

Note 11 – Preproduction Costs Related to Long-Term Supply Arrangements

We incur preproduction engineering and tooling costs related to the products produced for our customers under long-term supply agreements. We expense all preproduction engineering costs for which reimbursement is not contractually guaranteed by the customer or which are in excess of the contractually guaranteed reimbursement amount. We amortize the cost of the customer-owned tooling over the expected life of the wheel program on a straight-line basis. Also, we defer any reimbursements made to us by our customers and recognize the tooling reimbursement revenue over the same period in which the tooling is in use. Changes in the facts and circumstances of individual wheel programs may accelerate the amortization of both the cost of customer-owned tooling and the deferred tooling reimbursement revenues. Recognized tooling reimbursement revenues, which totaled $5.7 million and $6.2 million for the nine months ended October 1, 2017 and September 25, 2016, respectively, are included in net sales in the condensed consolidated statements of operations. The following tables summarize the unamortized customer-owned tooling costs included in our non-current assets, and the deferred tooling revenues included in accrued expenses and other non-current liabilities:

Goodwill and indefinite-lived assets, such as certain trade names acquired in connection with the acquisition of Uniwheels on May 30, 2017, are not amortized, but are instead evaluated for impairment on an annual basis at the end of the fiscal year, or more frequently if events or circumstances indicate that impairment may be more likely. During the three months ended October 1, 2017, no impairment charges have been taken against the company’s goodwill or indefinite-lived intangible assets. At October 1, 2017, the goodwill is $321.7 million, consisting of the initial balance of $306.2 million, increased for post-acquisition translation adjustments. The carrying amount of goodwill arose from the Acquisition described in Note 3, “Acquisition”.

The company’s other intangible assets primarily consist of assets with finite lives. These assets are amortized on a straight-line basis over their estimated useful lives. Following is a summary of the company’s finite-lived and indefinite-lived intangible assets as of October 1, 2017. There were no such intangible assets at December 31, 2016.

Amortization expense for these intangible assets was $6.9 million for the three month period ended October 1, 2017. The anticipated annual amortization expense for these intangible assets is $27.2 million for 2018 to 2021 and $25.3 million for 2022.

Note 13 – Redeemable Preferred Shares

On March 22, 2017, Superior and TPG Growth III Sidewall, L.P. (“TPG”) entered into an Investment Agreement pursuant to which Superior agreed to issue a number of shares of Series A Perpetual Convertible Preferred Stock (the “Series A redeemable preferred stock”) and Series B Perpetual Preferred Stock (the “Series B redeemable preferred stock”), par value $0.01 per share (the “Series A redeemable preferred stock” and “Series B redeemable preferred stock” referred to collectively as the

“redeemable preferred stock”) to TPG for an aggregate purchase price of $150.0 million (the “Investment”). As of the closing of the Investment on May 22, 2017, Superior issued 140,202 shares of Series A redeemable preferred stock, which was equal to 19.99 percent of Superior’s common stock outstanding on such date, and 9,798 shares of Series B redeemable preferred stock to TPG.

On August 30, 2017, our stockholders approved the conversion of 9,798 shares of Series B redeemable preferred stock into Series A redeemable preferred stock and all outstanding shares of Series B redeemable preferred stock were automatically converted into Series A redeemable preferred stock (the “Conversion”). Series A redeemable preferred stock has an initial stated value of $1,000 per share, par value of $0.01 per share and liquidation preference over common stock. Series A redeemable preferred stock is convertible into shares of Superior common stock equal to the number of shares determined by dividing the sum of the stated value and any accrued and unpaid dividends by the conversion price of $28.162. Series A redeemable preferred stock accrues dividends at a rate of 9 percent per annum, payable at Superior’s election either in-kind or in cash. Series A redeemable preferred stock is also entitled to participate in dividends on common stock in an amount equal to that which would have been due had the shares been converted into common stock.

We may mandate conversion of the Series A redeemable preferred stock if the price of the common stock exceeds $84.49. TPG may redeem the shares upon the occurrence of any of the following events (referred to as a “redemption event”): a change in control, recapitalization, merger, sale of substantially all of the company’s assets, liquidation or delisting of the company’s common stock. In addition, TPG may, at its option, unconditionally redeem the shares at any time after May 23, 2024. Superior may, at its option, redeem in whole at any time all of the shares of Series A redeemable preferred stock outstanding. If redeemed by either party on or before October 22, 2018, the redemption value (the “redemption value”) would be $262.5 million (1.75 times stated value). If redeemed after October 22, 2018, the redemption value would be the greater of $300 million (2.0 times stated value) or the product of the number of common shares into which the Series A redeemable preferred stock could be converted (5.3 million shares currently) and the then current market price of the common stock.

We have determined that the conversion option embedded in the redeemable preferred stock is required to be accounted for separately from the redeemable preferred stock as a derivative liability. Separation of the conversion option as a derivative liability is required because its economic characteristics are considered more akin to an equity instrument and therefore the conversion option is not considered to be clearly and closely related to the economic characteristics of the redeemable preferred stock. This is because the economic characteristics of the redeemable preferred stock are considered more akin to a debt instrument due to the fact that the shares are redeemable at the holder’s option, the redemption value is significantly greater than the face amount, the shares carry a fixed mandatory dividend, the stock price necessary to make conversion more attractive than redemption ($56.324) is significantly greater than the price at the date of issuance ($19.05), all of which lead to the conclusion that redemption is more likely than conversion.

We have also determined that the early redemption option exercisable upon the occurrence of a redemption event must also be bifurcated and accounted for separately from the redeemable preferred stock at fair value, because the debt host contract involves a substantial discount (face of $150 million as compared to the redemption value of $300 million) and the exercise of the early redemption option upon the occurrence of a redemption event would accelerate the holder’s option to redeem the shares.

Accordingly, we have recorded an embedded derivative liability representing the estimated combined fair value of the right of holders to receive common stock upon conversion (the “conversion option”) and the right of the holders to exercise their early redemption option upon the occurrence of a redemption event (the “early redemption option”). The embedded derivative liability is adjusted to reflect fair value at each period end with changes in fair value recorded in the “Change in fair value of redeemable preferred stock embedded derivative liability” financial statement line item of the company’s condensed consolidated statements of operations. Refer to “Note 6, Financial Instruments” for further information regarding the valuation of the embedded derivative.

Since the redeemable preferred stock may be redeemed at the option of the holder, but is not mandatorily redeemable, the redeemable preferred stock has been classified as mezzanine equity and initially recognized at fair value of $150 million (the proceeds on the date of issuance) less issuance costs of $3.7 million, resulting in an initial value of $146.3 million. This amount has been further reduced by $10.9 million assigned to the embedded derivative liability at date of issuance, resulting in an adjusted initial value of $135.4 million. We are accreting the difference between the adjusted initial value of $135.4 million and the redemption value of $300 million over the seven-year period from date of issuance through May 23, 2024 (the date at which the holder has the unconditional right to redeem the shares, deemed to be the earliest likely redemption date) using the effective interest method. The accretion to the carrying value of the redeemable preferred stock is treated as a deemed dividend, recorded as a charge to retained earnings and deducted in computing earnings per share (analogous to the treatment for stated and participating dividends paid on the redeemable preferred shares). We have accreted $5.2 million through October 1, 2017 resulting in a balance of $140.6 million.

Note 14 – Earnings Per Share

In accordance with U.S. GAAP, basic earnings per share is computed by dividing net income (loss), less preferred dividends, by the weighted average number of common shares outstanding. For purposes of calculating diluted earnings per share, net income is divided by the total of the weighted average shares outstanding plus the dilutive effect of our redeemable preferred stock, outstanding stock options and time and performance based restricted stock units under the treasury stock method, which includes consideration of stock-based compensation required by U.S. GAAP.
