FORWARD-LOOKING STATEMENTS
In this Quarterly Report on Form 10-Q (Quarterly Report), we make statements concerning our expectations, beliefs, plans, objectives, goals, strategies, and future events or performance. Such statements are “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995 and relate to trends and events that may affect our future financial position and operating results. The terms such as “will,” “may,” “could,” “would,” “plan,” “believe,” “expect,” “anticipate,” “intend,” “project,” "target," and similar words or expressions, as well as statements in future tense, are intended to identify forward-looking statements.
Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking statements are based on information available at the time those statements are made and/or management’s good faith belief as of that time with respect to future events and are subject to risks and may differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:
•significant disruptions in production, sales and/or supply as a result of public health crises, including pandemic or epidemic illness such as Novel Coronavirus (COVID-19), or otherwise;
•global economic conditions;
•reduced purchases of our products by General Motors Company (GM), Stellantis N.V. (Stellantis), Ford Motor Company (Ford) or other customers;
•our ability to respond to changes in technology, increased competition or pricing pressures;
•our ability to develop and produce new products that reflect market demand;
•lower-than-anticipated market acceptance of new or existing products;
•our ability to attract new customers and programs for new products;
•reduced demand for our customers' products (particularly light trucks and sport utility vehicles (SUVs) produced by GM, Stellantis and Ford);
•risks inherent in our global operations (including tariffs and the potential consequences thereof to us, our suppliers, and our customers and their suppliers, adverse changes in trade agreements, such as United States-Mexico-Canada Agreement (USMCA), immigration policies, political stability, taxes and other law changes, potential disruptions of production and supply, and currency rate fluctuations);
•a significant disruption in operations at one or more of our key manufacturing facilities;
•negative or unexpected tax consequences;
•risks related to a failure of our information technology systems and networks, and risks associated with current and emerging technology threats and damage from computer viruses, unauthorized access, cyber attacks and other similar disruptions;
•supply shortages, such as the semiconductor shortage that the automotive industry is currently experiencing, or price increases in raw material and/or freight, utilities or other operating supplies for us or our customers as a result of pandemics, natural disasters or otherwise;
•availability of financing for working capital, capital expenditures, research and development (R&D) or other general corporate purposes including acquisitions, as well as our ability to comply with financial covenants;
•our customers' and suppliers' availability of financing for working capital, capital expenditures, R&D or other general corporate purposes;
•an impairment of our goodwill, other intangible assets, or long-lived assets if our business or market conditions indicate that the carrying values of those assets exceed their fair values;
•liabilities arising from warranty claims, product recall or field actions, product liability and legal proceedings to which we are or may become a party, or the impact of product recall or field actions on our customers;
•our ability or our customers' and suppliers' ability to successfully launch new product programs on a timely basis;
•our ability to maintain satisfactory labor relations and avoid work stoppages;
•our suppliers', our customers' and their suppliers' ability to maintain satisfactory labor relations and avoid work stoppages;
•our ability to achieve the level of cost reductions required to sustain global cost competitiveness;
•our ability to realize the expected revenues from our new and incremental business backlog;
•price volatility in, or reduced availability of, fuel;
•our ability to protect our intellectual property and successfully defend against assertions made against us;
•risks of noncompliance with environmental laws and regulations or risks of environmental issues that could result in unforeseen costs at our facilities, or reputational damage;
•adverse changes in laws, government regulations or market conditions affecting our products or our customers' products;
•our ability or our customers' and suppliers' ability to comply with regulatory requirements and the potential costs of such compliance;
•changes in liabilities arising from pension and other postretirement benefit obligations;
•our ability to attract and retain key associates; and
•other unanticipated events and conditions that may hinder our ability to compete.
It is not possible to foresee or identify all such factors and any or all of the foregoing factors may be exacerbated by COVID-19. Further, we make no commitment to update any forward-looking statement or to disclose any facts, events or circumstances after the date hereof that may affect the accuracy of any forward-looking statement.

1. ORGANIZATION AND BASIS OF PRESENTATION
Organization We are a global Tier 1 supplier to the automotive industry. We design, engineer and manufacture driveline and metal forming technologies that are making the next generation of vehicles smarter, lighter, safer and more efficient. We employ approximately 20,000 associates, operating at nearly 80 facilities in 17 countries, to support our customers on global and regional platforms with a continued focus on delivering quality, operational excellence and technology leadership.
Basis of Presentation We have prepared the accompanying interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q under the Securities Exchange Act of 1934. These condensed consolidated financial statements are unaudited but include all normal recurring adjustments, which we consider necessary for a fair presentation of the information set forth herein. Results of operations for the periods presented are not necessarily indicative of the results for the full fiscal year.
The balance sheet at December 31, 2020 presented herein has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete consolidated financial statements.
In order to prepare the accompanying interim condensed consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts and disclosures in our interim condensed consolidated financial statements. These estimates and assumptions are impacted by risks and uncertainties, including those associated with the Novel Coronavirus (COVID-19) pandemic and the semiconductor supply shortage that is impacting the automotive industry. While we have made estimates and assumptions based on the facts and circumstances available as of the date of this report, the full impact of COVID-19 and the semiconductor shortage cannot be predicted, and actual results could differ materially from those estimates and assumptions.
For further information, refer to the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2020.
Sale of Interest in Consolidated Joint Venture
In the first quarter of 2021, we completed the sale of substantially all of our ownership interest in a consolidated joint venture and received cash proceeds of approximately $2.4 million. As a result of the sale and deconsolidation of this joint venture, we recognized a loss of $2.6 million. Subsequent to the sale of this joint venture, we no longer present noncontrolling interest in our condensed consolidated financial statements as all consolidated entities are wholly-owned.
Commencement of Lease of European Headquarters and Engineering Center (EHEC)
In the first quarter of 2021, the lease of our new EHEC in Langen, Germany commenced. This lease has a term of 20 years and is classified as a finance lease. We recognized a right-of-use (ROU) asset and finance lease liability of approximately $49 million upon commencement of this lease. The ROU asset is presented in Property, plant and equipment, net and the finance lease liability is presented in Accrued expenses and other (current portion), and Postretirement benefits and other long-term liabilities (long-term portion) in our Condensed Consolidated Balance Sheet at March 31, 2021.

Effect of New Accounting Standards and Other Regulatory Pronouncements
Accounting Standard Update 2020-04
On March 12, 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2020-04 - Reference Rate Reform (Topic 848), and has subsequently issued ASU 2021-01 - Reference Rate Reform (Topic 848). This guidance provides optional expedients and exceptions that are intended to ease the burden of updating contracts to contain a new reference rate due to the discontinuation of the London Inter-Bank Offered Rate (LIBOR). This guidance is available immediately and may be implemented in any period prior to the guidance expiration on December 31, 2022. We expect to utilize certain of the optional expedients and exceptions available under ASU 2020-04 and ASU 2021-01 and we do not expect the adoption of this guidance to have a material impact on our financial statements.
Accounting Standard Update 2019-12
On December 18, 2019, the FASB issued ASU 2019-12 - Income Taxes (Topic 740). This guidance is intended to simplify the accounting and disclosure requirements for income taxes by removing various exceptions and requires that the effect of an enacted change in tax laws or rates be included in the annual effective tax rate computation in the interim period of the enactment. This guidance became effective and we adopted this guidance on January 1, 2021. The adoption of this guidance did not have a material impact on our consolidated financial statements.
Coronavirus Aid, Relief, and Economic Security Act
The Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) was enacted on March 27, 2020 in the United States. The key provisions of the CARES Act, as they remain applicable to AAM, include the following:
•The ability to use net operating losses (NOLs) to offset income without the 80% taxable income limitation enacted as part of the Tax Cuts and Jobs Act (TCJA) of 2017, and to carry back NOLs to offset prior year income for five years. These are temporary provisions that apply to NOLs incurred in 2018, 2019 or 2020 tax years. We recognized a tax benefit of $14.4 million for the year ended December 31, 2020 related to our ability to carry back prior year losses, as well as projected current year losses, under the CARES Act to years with the previous 35% tax rate. We received an income tax refund of approximately $6.0 million during the first quarter of 2021 as a result of this provision of the CARES Act.
•The ability to defer the payment of the employer portion of social security taxes incurred between March 27, 2020 and December 31, 2020, with 50% of the deferred amount to be paid by December 31, 2021 and the remaining 50% to be paid by December 31, 2022. At March 31, 2021, we had deferred $15.2 million of social security taxes that will be paid in the fourth quarter of 2021 and the fourth quarter of 2022.
•The ability to claim an Employee Retention Credit (ERC), which is a refundable payroll tax credit, for 50% of qualified wages or benefits, subject to certain limitations, that are paid to an employee when they are not providing services due to COVID-19. The ERC applied to qualified wages paid or incurred during the period March 13, 2020 through December 31, 2020 and was available to eligible employers whose operations were fully or partially suspended due to COVID-19, or whose gross receipts declined by more than 50% when compared to the applicable period in the prior year. At March 31, 2021, we have a refundable ERC amount of $6.7 million included in Prepaid expenses and other in our Condensed Consolidated Balance Sheet.

2. RESTRUCTURING AND ACQUISITION-RELATED COSTS
In the first quarter of 2020, we initiated a new global restructuring program (the 2020 Program). The primary objectives of the 2020 Program are to achieve efficiencies within our corporate and business unit support teams to reduce cost in our business, and to structurally adjust our operations based on the impact of COVID-19. We expect to incur costs under the 2020 Program into 2022.
A summary of our restructuring activity for the first three months of 2021 and 2020 is shown below:

| Severance Charges |  | Implementation Costs |  |  |  | Total
| (in millions)
Accrual at December 31, 2019 | $ | 4.8 |  |  | $ | 7.4 |  |  |  |  | $ | 12.2 |
Charges | 2.2 |  |  | 12.5 |  |  |  |  | 14.7 |
Cash utilization | (6.6) |  |  | (5.5) |  |  |  |  | (12.1) |
Accrual at March 31, 2020 | $ | 0.4 |  |  | $ | 14.4 |  |  |  |  | $ | 14.8 |
Accrual at December 31, 2020 | $ | 1.7 |  |  | $ | 9.8 |  |  |  |  | $ | 11.5 |
Charges | 0.5 |  |  | 16.0 |  |  |  |  | 16.5 |
Cash utilization | (2.2) |  |  | (19.4) |  |  |  |  | (21.6) |
Accrual at March 31, 2021 | $ | — |  |  | $ | 6.4 |  |  |  |  | $ | 6.4 |

As part of our restructuring actions, we incurred total severance charges of approximately $0.5 million and $2.2 million during the three months ended March 31, 2021 and 2020, respectively. We also incurred total implementation costs of approximately $16.0 million and $12.5 million during the three months ended March 31, 2021 and 2020, respectively. Implementation costs consist primarily of professional fees and plant exit costs.
Substantially all of the restructuring costs incurred during the three months ended March 31, 2021 were under the 2020 Program. Approximately $1.2 million and $0.5 million of our total restructuring costs for the three months ended March 31, 2021 related to our Driveline and Metal Forming segments, respectively, while the remainder were corporate costs. Approximately $6.8 million and $5.2 million of our total restructuring costs for the three months ended March 31, 2020 related to our Driveline and Metal Forming segments, respectively, while the remainder were corporate costs. We expect to incur approximately $50 million to $65 million of total restructuring charges in 2021, including costs incurred under the 2020 Program.
During the three months ended March 31, 2021 and 2020, we incurred the following integration charges primarily related to the integration of MPG:

|  |  |  |  | Integration Expenses |  |
|  |  |  |  | (in millions)
Charges for the three months ended March 31, 2021 |  |  |  |  | $ | 1.0 |  |  |
Charges for the three months ended March 31, 2020 |  |  |  |  | 2.9 |  |  |

These integration expenses primarily reflect costs incurred for information technology infrastructure and enterprise resource planning systems. Total restructuring charges and acquisition-related charges are presented on a separate line item titled Restructuring and acquisition-related costs in our Condensed Consolidated Statements of Operations, and totaled $17.5 million for the three months ended March 31, 2021 and $17.6 million for the three months ended March 31, 2020.

3. INVENTORIES
We state our inventories at the lower of cost or net realizable value. The cost of our inventories is determined using the first-in first-out method. When we determine that our gross inventories exceed usage requirements, or if inventories become obsolete or otherwise not saleable, we record a provision for such loss as a component of our inventory accounts.
Inventories consist of the following:

4. GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill The following table provides a reconciliation of changes in goodwill for the three months ended March 31, 2021:

|  |  |  |  | Consolidated
|  |  |  |  | (in millions)
Balance at December 31, 2020 |  |  |  |  | $ | 185.7 |
Foreign currency translation |  |  |  |  | (1.0) |
Balance at March 31, 2021 |  |  |  |  | $ | 184.7 |

We conduct our annual goodwill impairment test in the fourth quarter of each year, as well as whenever adverse events or changes in circumstances indicate a possible impairment. In performing this test, we utilize a third-party valuation specialist to assist management in determining the fair value of our reporting units. Fair value of each reporting unit is estimated based on a combination of discounted cash flows and the use of pricing multiples derived from an analysis of comparable public companies multiplied against historical and/or anticipated financial metrics of each reporting unit. These calculations contain uncertainties as they require management to make assumptions including, but not limited to, market comparables, future cash flows of the reporting units, and appropriate discount and long-term growth rates. This fair value determination is categorized as Level 3 within the fair value hierarchy.
In the first quarter of 2020, the reduction in global automotive production volumes caused by the impact of COVID-19 represented an indicator to test our goodwill for impairment. This reduction in production volumes began in March of 2020 and resulted in lower forecasted sales volumes in the periods included in our long-range plan as revised in the first quarter of 2020.
As a result of this goodwill impairment test in the first quarter of 2020, we determined that the carrying values of both our Driveline and Metal Forming reporting units were greater than their respective fair values. As such, we recorded a goodwill impairment charge of $510.0 million in the first quarter of 2020, of which $210.8 million was associated with our Driveline reporting unit and $299.2 million was associated with our Metal Forming reporting unit. The Metal Forming impairment charge represented a full impairment of the goodwill associated with that reporting unit. As a result, all remaining goodwill is attributable to our Driveline reporting unit.
These impairment charges were primarily the result of a decline in the projected cash flows of these reporting units under our revised long-range plan completed in the first quarter of 2020. The revision to our long-range plan was driven by lower forecasted sales volumes in the internal and external data sources used to form our projections primarily due to the reduction in global automotive production volumes caused by the impact of COVID-19. The impairment charges were also the result of changes in certain market-related inputs to the analysis to reflect macro-economic changes caused by the impact of COVID-19, including increased discount rates and lower pricing multiples for comparable public companies. At March 31, 2021, accumulated goodwill impairment losses were $1,435.5 million.
The reduction in production volumes and changes to macro-economic factors caused by the impact of COVID-19 also represented an indicator to test our long-lived assets, including other intangible assets and property, plant and equipment, for impairment. We completed this test in the first quarter of 2020 and there was no impairment of these assets.

Senior Secured Credit Facilities In 2017, American Axle & Manufacturing Holdings, Inc. (Holdings) and American Axle & Manufacturing, Inc. (AAM, Inc.) entered into a credit agreement (the Credit Agreement). In connection with the Credit Agreement, Holdings, AAM, Inc. and certain of their restricted subsidiaries entered into a Collateral Agreement and Guarantee Agreement with the financial institutions party thereto. The Credit Agreement, as amended in July 2019 (First Amendment), includes a $340 million term loan A facility (the Term Loan A Facility due 2024), a $1.55 billion term loan B facility (the Term Loan B Facility due 2024) and a $925 million multi-currency revolving credit facility (the Revolving Credit Facility, and together with the Term Loan A Facility due 2024 and the Term Loan B Facility due 2024, the Senior Secured Credit Facilities). The Term Loan A Facility due 2024 and the Term Loan B Facility due 2024 have been paid down from the original amounts through both scheduled and voluntary payments. There are no scheduled payments under the Term Loan B due 2024 until maturity.
In April 2020, Holdings, AAM, Inc., and certain subsidiaries of Holdings entered into the Second Amendment (Second Amendment) to the Credit Agreement. For the period from April 1, 2020 through March 31, 2022 (the Amendment Period), the Second Amendment, among other things, replaced the total net leverage ratio covenant with a new senior secured net leverage ratio covenant, reduced the minimum levels of the cash interest expense coverage ratio covenant, and modified certain covenants restricting the ability of Holdings, AAM and certain subsidiaries of Holdings to create, incur, assume or permit to exist certain additional indebtedness and liens and to make certain restricted payments, voluntary payments and distributions. The Second Amendment also increased the maximum levels of the total net leverage ratio covenant after the Amendment Period, modified the applicable margin with respect to interest rates under the Term Loan A Facility due 2024 and interest rates and commitment fees under the Revolving Credit Facility, and increased the minimum adjusted London Interbank Offered Rate for Eurodollar-based loans under the Term Loan A Facility due 2024 and Revolving Credit Facility. The applicable margin for the Term Loan B Facility remains unchanged.
In February 2021, we made a voluntary prepayment of $100.0 million on our Term Loan B Facility due 2024 and $4.3 million on our Term Loan A Facility due 2024. As a result, we expensed approximately $1.1 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the expected life of these borrowings.
At March 31, 2021, we had $894.1 million available under the Revolving Credit Facility. This availability reflects a reduction of $30.9 million for standby letters of credit issued against the facility. The proceeds of the Revolving Credit Facility are used for general corporate purposes.

The Senior Secured Credit Facilities provide back-up liquidity for our foreign credit facilities. We intend to use the availability of long-term financing under the Senior Secured Credit Facilities to refinance any current maturities related to such debt agreements that are not otherwise refinanced on a long-term basis in their local markets, except where otherwise reclassified to Current portion of long-term debt on our Condensed Consolidated Balance Sheet.
Subsequent Event In April 2021, we made a voluntary prepayment of $88.8 million on our Term Loan B Facility due 2024. As a result, we expect to expense approximately $0.9 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing.
Redemption of 6.625% Notes due 2022 In the first quarter of 2020, we voluntarily redeemed a portion of our 6.625% Notes due 2022. This resulted in a principal payment of $100.0 million and $2.0 million in accrued interest. We also expensed approximately $0.4 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing, and approximately $1.1 million for an early redemption premium.
Foreign credit facilities We utilize local currency credit facilities to finance the operations of certain foreign subsidiaries. At March 31, 2021, $109.0 million was outstanding under our foreign credit facilities, as compared to $88.8 million at December 31, 2020. At March 31, 2021, an additional $58.6 million was available under our foreign credit facilities.
Weighted-Average Interest Rate The weighted-average interest rate of our long-term debt outstanding was 5.8% at both March 31, 2021 and December 31, 2020.

6. DERIVATIVES
Our business and financial results are affected by fluctuations in global financial markets, including interest rates and currency exchange rates. Our hedging policy has been developed to manage these risks to an acceptable level based on management’s judgment of the appropriate trade-off between risk, opportunity and cost. We do not hold financial instruments for trading or speculative purposes.
Currency derivative contracts From time to time, we use foreign currency forward contracts to reduce the effects of fluctuations in exchange rates relating to certain foreign currencies. As of March 31, 2021 and December 31, 2020, we had currency forward contracts outstanding with a total notional amount of $171.3 million and $178.2 million, respectively, that hedge our exposure to changes in foreign currency exchange rates for certain payroll expenses into the fourth quarter of 2023 and the purchase of certain direct and indirect inventory and other working capital items into the fourth quarter of 2021.
Fixed-to-fixed cross-currency swap In 2019, we entered into a fixed-to-fixed cross-currency swap to reduce the variability of functional currency equivalent cash flows associated with changes in exchange rates on certain Euro-based intercompany loans. In the first quarter of 2020, we discontinued this fixed-to-fixed cross-currency swap, which was in an asset position of $9.8 million on the date that it was discontinued.
Also in the first quarter of 2020, we entered into a new fixed-to-fixed cross-currency swap to reduce the variability of functional currency equivalent cash flows associated with changes in exchange rates on certain Euro-based intercompany loans. As of March 31, 2021 and December 31, 2020, the notional amount of the fixed-to-fixed cross-currency swap was $234.6 million and $244.2 million, respectively, and hedges our exposure to changes in exchange rates on the intercompany loans into the second quarter of 2024.
Variable-to-fixed interest rate swap In 2019, we entered into a variable-to-fixed interest rate swap to reduce the variability of cash flows associated with interest payments on our variable rate debt. We have the following notional amounts hedged in relation to our variable-to-fixed interest rate swap: $900.0 million through May 2021, $750.0 million through May 2022, $600.0 million through May 2023 and $500.0 million through May 2024.

7. FAIR VALUE
ASC 820 - Fair Value Measurement defines fair value as “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.” The definition is based on an exit price rather than an entry price, regardless of whether the entity plans to hold or sell the asset. This guidance also establishes a fair value hierarchy to prioritize inputs used in measuring fair value as follows:
•Level 1: Observable inputs such as quoted prices in active markets;
•Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
•Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
Financial instruments The estimated fair value of our financial assets and liabilities that are recognized at fair value on a recurring basis, using available market information and other observable data, are as follows:

Cash flow hedges - variable-to-fixed interest rate swap |  | 25.5 |  |  | 25.5 |  |  | 32.1 |  |  | 32.1 |  |  | Level 2

The carrying values of our cash, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the short-term maturities of these instruments. The carrying values of our borrowings under the foreign credit facilities approximate their fair value due to the frequent resetting of the interest rates.

The noncurrent liabilities associated with our pension and other postretirement benefit plans are classified as Postretirement benefits and other long-term liabilities on our Condensed Consolidated Balance Sheets. As of March 31, 2021 and December 31, 2020, we have a noncurrent pension liability of $134.5 million and $141.2 million, respectively. As of March 31, 2021 and December 31, 2020, we have a noncurrent other postretirement benefits liability of $554.2 million and $556.7 million, respectively.
Due to the availability of our pre-funded pension balances (previous contributions in excess of prior required pension contributions), we expect our regulatory pension funding requirements in 2021 to be less than $1 million. We expect our cash payments for other postretirement benefit obligations in 2021, net of GM cost sharing, to be approximately $17 million.

9. PRODUCT WARRANTIES
We record a liability for estimated warranty obligations at the dates our products are sold. These estimates are established using sales volumes and internal and external warranty data where there is no payment history and historical information about the average cost of warranty claims for customers with prior claims. We estimate our costs based on the contractual arrangements with our customers, existing customer warranty terms and internal and external warranty data, which includes a determination of our warranty claims and actions taken to improve product quality and minimize warranty claims. We continuously evaluate these estimates and our customers' administration of their warranty programs. We monitor actual warranty claim data and adjust the liability, as necessary, on a quarterly basis.
The following table provides a reconciliation of changes in the product warranty liability:

10. INCOME TAXES
We adjust our effective tax rate each quarter based on our estimated annual effective tax rate. We also record the tax impact of certain discrete, unusual or infrequently occurring items, including changes in judgment about valuation allowances and the effects of changes in tax laws or rates on deferred tax balances, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.
Income tax expense was $8.8 million for the three months ended March 31, 2021, an effective income tax rate of 18.6%, as compared to income tax expense of $3.3 million for the three months ended March 31, 2020, an effective income tax rate of (0.7)%.
During the three months ended March 31, 2020, we recognized a net tax benefit of approximately $7.5 million related to our ability to carry back losses from prior years under the CARES Act. This income tax benefit was the result of our ability to carry back losses to tax years with the higher 35% corporate income tax rate.
Our effective income tax rate for the three months ended March 31, 2021 varies from our effective income tax rate for the three months ended March 31, 2020 primarily as a result of the impact of the goodwill impairment charge recorded during the first quarter of 2020, which had no corresponding income tax benefit. For the three months ended March 31, 2021 and 2020, our effective income tax rates vary from the U.S. federal statutory rate of 21% primarily due to favorable foreign tax rates, the impact of tax credits, and the effect of the goodwill impairment charge in the first quarter of 2020.
In accordance with the guidance in ASC 740 - Income Taxes, we review the likelihood that we will realize the benefit of deferred tax assets and estimate whether recoverability of our deferred tax assets is "more likely than not" based on the available evidence. Due to the uncertainty associated with the extent and ultimate impact of COVID-19 and the semiconductor shortage on global automotive production volumes, we may experience lower than projected earnings in certain jurisdictions in future periods, and it is reasonably possible that changes in valuation allowances could be recognized in the next twelve months as a result.
We operate in multiple jurisdictions throughout the world and the income tax returns of several subsidiaries in various tax jurisdictions are currently under examination. We are currently under a U.S. federal income tax examination for the years 2015 through 2018. Generally, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years prior to 2013.
Based on the status of ongoing tax audits, and the protocol of finalizing audits by the relevant tax authorities, it is not possible to estimate the impact of changes, if any, to previously recorded uncertain tax positions. We will continue to monitor the progress and conclusions of all ongoing audits and other communications with tax authorities, and will adjust our estimated liability as necessary. As of March 31, 2021 and December 31, 2020, we have recorded a liability for unrecognized income tax benefits and related interest and penalties of $22.4 million and $22.2 million, respectively.

14. MANUFACTURING FACILITY FIRE AND INSURANCE RECOVERY
On September 22, 2020, a significant industrial fire occurred at our Malvern Manufacturing Facility in Ohio (Malvern Fire). All associates were evacuated safely and without injury. We continue to focus on managing this disruption and protecting continuity of supply to our customers, including utilizing production capacity and resources at other AAM facilities.
Our insurance policies are expected to cover the repair, replacement or actual cash value of the assets that incurred loss or damage, less our applicable deductible of $1.0 million. In addition, our insurance policies are expected to provide coverage for interruption to our business, including lost or reduced profits and reimbursement for certain expenses and costs that are incurred relating to the fire. In the three months ended March 31, 2021, we recorded $8.3 million of charges primarily related to transportation and freight, asset repairs and other costs incurred to resume or relocate operations and ensure continuity of supply to our customers. We also recorded an estimated insurance recovery of $7.1 million and received advances under our insurance policies of $11.4 million in the three months ended March 31, 2021. This resulted in a net pre-tax impact to our Condensed Consolidated Statement of Operations of approximately $1.2 million in Cost of goods sold for the three months ended March 31, 2021. At March 31, 2021, $38.8 million of insurance recovery receivable is included in Prepaid expenses and other in our Condensed Consolidated Balance Sheet.
In the fourth quarter of 2020, we determined that we will cease production at the Malvern Manufacturing Facility and relocate production capacity to other AAM manufacturing facilities during 2021. As such, we cannot estimate the total claim eligible costs that we will incur as a result of the Malvern Fire and the associated relocation of production capacity to other AAM manufacturing facilities. At March 31, 2021, we have estimated the amount of expected insurance proceeds recoverable in consideration of the policy provisions, carrying amount of the PP&E that was written-down, and claim eligible expenses incurred from the date of the fire. We expect the claim settlement process to continue through 2021, however, based on the provisions of the policy the process could continue into 2022. We will update our estimates as additional information becomes available, however, the actual impact on our results of operations, financial position or cash flows, or the timing of such impact, could differ from our estimates.

15. SEGMENT REPORTING
Our business is organized into Driveline and Metal Forming segments, with each representing a reportable segment under ASC 280 Segment Reporting. In the first quarter of 2021, we completed a reorganization of our segments, which included moving certain locations that were previously reported under our Driveline segment to our Metal Forming segment in order to better align our product and process technologies. The amounts in the tables below for the three months ended March 31, 2020 have been retrospectively restated to reflect this reorganization.
The results of each segment are regularly reviewed by the chief operating decision maker to assess the performance of the segment and make decisions regarding the allocation of resources to the segments.
Our product offerings by segment are as follows:
•Driveline products consist primarily of front and rear axles, driveshafts, differential assemblies, clutch modules, balance shaft systems, disconnecting driveline technology, and electric and hybrid driveline products and systems for light trucks, sport utility vehicles (SUVs), crossover vehicles, passenger cars and commercial vehicles; and
•Metal Forming products consist primarily of axle and transmission shafts, ring and pinion gears, differential gears and assemblies, connecting rods and variable valve timing products for Original Equipment Manufacturers and Tier 1 automotive suppliers.
We use Segment Adjusted EBITDA as the measure of earnings to assess the performance of each segment and determine the resources to be allocated to the segments. We define EBITDA to be earnings before interest expense, income taxes, depreciation and amortization. Segment Adjusted EBITDA is defined as EBITDA for our reportable segments excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, loss on the sale of a business, impairment charges, pension settlements and non-recurring items.
The following tables represent information by reportable segment for the three months ended March 31, 2021 and 2020 (in millions):

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
This management’s discussion and analysis (MD&A) should be read in conjunction with the unaudited condensed consolidated financial statements and notes appearing elsewhere in this Quarterly Report and our Annual Report on Form 10-K for the year ended December 31, 2020.
Unless the context otherwise requires, references to "we," "our," "us" or "AAM" shall mean collectively (i) American Axle & Manufacturing Holdings, Inc. (Holdings), a Delaware corporation, (ii) American Axle & Manufacturing, Inc. (AAM, Inc.), a Delaware corporation, and its direct and indirect subsidiaries, and, (iii) Metaldyne Performance Group, Inc. (MPG) and its direct and indirect subsidiaries. AAM Inc. and MPG are wholly-owned subsidiaries of Holdings.
COMPANY OVERVIEW
We are a global Tier 1 supplier to the automotive industry. We design, engineer and manufacture driveline and metal forming technologies that are making the next generation of vehicles smarter, lighter, safer and more efficient. We employ approximately 20,000 associates, operating at nearly 80 facilities in 17 countries, to support our customers on global and regional platforms with a focus on quality, operational excellence and technology leadership.
Major Customers
We are a primary supplier of driveline components to General Motors Company (GM) for its full-size rear-wheel drive (RWD) light trucks, sport utility vehicles (SUVs), and crossover vehicles manufactured in North America, supplying a significant portion of GM’s rear axle and four-wheel drive and all-wheel drive (4WD/AWD) axle requirements for these vehicle platforms. We also supply GM with various products from our Metal Forming segment. Sales to GM were approximately 37% of our consolidated net sales in the first three months of 2021, 41% in the first three months of 2020, and 39% for the full year 2020.
We also supply driveline system products to Stellantis N.V. (Stellantis) for programs including the heavy-duty Ram full-size pickup trucks and its derivatives, the AWD Chrysler Pacifica and the AWD Jeep Cherokee. In addition, we sell various products to Stellantis from our Metal Forming segment. Sales to Stellantis were approximately 19% of our consolidated net sales in the first three months of 2021, 16% in the first three months of 2020, and 19% for the full year 2020.
We are also a supplier to Ford Motor Company (Ford) for driveline system products on certain vehicle programs including the Ford Bronco Sport, Ford Edge, Ford Escape and Lincoln Nautilus, and we sell various products to Ford from our Metal Forming segment. Sales to Ford were approximately 12% of our consolidated net sales in the first three months of 2021, and were also 12% for both the first three months of 2020 and the full year of 2020.
No other customer represented 10% or more of consolidated net sales during these periods.
COVID-19 Update
In the first quarter of 2021, our operations continued to return to more normalized levels of production and we did not experience significant reductions in production volumes as a result of the impact of COVID-19. Continuing to sustain increased levels of production will depend on future developments, including the number of COVID-19 cases reported, the potential reimplementation of shelter-in-place orders, and customer production levels, which are outside of our control. We continue to monitor the impact of COVID-19 on our operations, as well as the operations of our customers and suppliers, as a resurgence in cases could have a sudden and significant impact on our operations, financial condition and financial results.
28

RESULTS OF OPERATIONS –– THREE MONTHS ENDED MARCH 31, 2021 AS COMPARED TO THREE MONTHS ENDED MARCH 31, 2020
Net Sales Net sales were $1,425.1 million in the first quarter of 2021, as compared to $1,343.5 million in the first quarter of 2020. The increase in net sales in the first quarter of 2021, as compared to the first quarter of 2020, primarily reflects increased production volumes as net sales in the first quarter of 2020 were adversely impacted by an estimated $169 million associated with the decline in global automotive production as a result of COVID-19. Net sales in the first quarter of 2021, as compared to the first quarter of 2020, also increased by approximately $44 million associated with the effect of metal market pass-throughs to our customers and the impact of foreign exchange related to translation adjustments. These increases were partially offset by a reduction in production volumes on certain vehicle programs that we support as a result of the semiconductor shortage that is impacting the automotive industry, the impact of which we estimate to be approximately $64 million for the first quarter of 2021.
We are monitoring the semiconductor supply shortage as it may continue to adversely impact automotive production volumes. Due to the uncertainty associated with the semiconductor shortage, the ultimate impact on our net sales and results of operations is unknown.
Cost of Goods Sold Cost of goods sold was $1,198.0 million in the first quarter of 2021, as compared to $1,148.2 million in the first quarter of 2020. The change in cost of goods sold principally reflects the net increase in production volumes on the vehicle programs we support in the first quarter of 2021, as compared to the first quarter of 2020, as well as an increase of approximately $44 million associated with the effect of metal market pass-throughs to our customers and the impact of foreign exchange related to translation adjustments. For the three months ended March 31, 2021, material costs were approximately 59% of total cost of goods sold, as compared to approximately 57% for the three months ended March 31, 2020.
In the first quarter of 2021, one of our Major Customers announced their intention to cease production operations in Brazil in 2021 as part of their restructuring actions. This decision impacts certain of the programs that we support and, as a result, we have accelerated depreciation on certain property, plant and equipment beginning in the first quarter of 2021. The impact on cost of goods sold of this acceleration was approximately $11 million in the first quarter of 2021 and we expect the full year impact to be approximately $32 million.
Gross Profit Gross profit was $227.1 million in the first quarter of 2021, as compared to $195.3 million in the first quarter of 2020. Gross margin was 15.9% in the first quarter of 2021, as compared to 14.5% in the first quarter of 2020. Gross profit and gross margin were impacted by the factors discussed in Net Sales and Cost of Goods Sold above.
Selling, General and Administrative Expenses (SG&A) SG&A (including research and development (R&D)) was $90.0 million or 6.3% of net sales in the first quarter of 2021, as compared to $90.3 million or 6.7% of net sales in the first quarter of 2020. R&D expense, net of customer engineering, design and development (ED&D) recoveries, was approximately $31.7 million in the first quarter of 2021, as compared to $36.6 million in the first quarter of 2020. The decrease in SG&A expense in the three months ended March 31, 2021, as compared to the three months ended March 31, 2020, was primarily attributable to lower net R&D expense, partially offset by higher incentive compensation accruals.
Amortization of Intangible Assets Amortization expense related to intangible assets was $21.5 million for the three months ended March 31, 2021 and $21.8 million for the three months ended March 31, 2020.
Impairment Charge In the first quarter of 2020, the reduction in global automotive production volumes caused by the impact of COVID-19 represented an indicator to test our goodwill for impairment. As a result of this goodwill impairment test, we determined that the carrying values of our Driveline and Metal Forming reporting units were greater than their respective fair values. As such, we recorded a total goodwill impairment charge of $510.0 million in the first quarter of 2020. See Note 4 - Goodwill and Other Intangible Assets for further detail.
Restructuring and Acquisition-Related Costs Restructuring and acquisition-related costs were $17.5 million in the first quarter of 2021 and $17.6 million in the first quarter of 2020. See Note 2 - Restructuring and Acquisition-Related Costs for additional detail. We expect to incur approximately $50 million to $65 million of total restructuring costs in 2021. In addition, we expect to incur approximately $5 million of integration charges in 2021 as we finalize the integration of ERP systems at legacy MPG locations.
Loss on Sale of Business In the first quarter of 2021, we completed the sale of substantially all of our ownership interest in a consolidated joint venture. As a result of the sale and deconsolidation of this joint venture, we recognized a loss of $2.6 million. In the first quarter of 2020, we finalized certain customary post-closing calculations associated with the sale of the U.S.
29

operations of our Casting business that was completed in the fourth quarter of 2019, resulting in an additional loss of $1.0 million.
Operating Income (Loss) Operating income was $95.5 million in the first quarter of 2021, as compared to operating loss of $445.4 million in the first quarter of 2020. Operating margin was 6.7% in the first quarter of 2021, as compared to (33.2)% in the first quarter of 2020. The changes in operating income (loss) and operating margin were primarily due to factors discussed in Net Sales, Cost of Goods Sold and Impairment Charge above.
Interest Expense and Interest Income Interest expense was $51.1 million in the first quarter of 2021, as compared to $51.5 million in the first quarter of 2020. Interest income was $2.9 million in the first quarter of 2021, as compared to $2.8 million in the first quarter of 2020. The weighted-average interest rate of our long-term debt outstanding was 5.9% in the first quarter of 2021 and 5.8% in the first quarter of 2020. We expect our interest expense in 2021 to be approximately $195 million to $205 million.
Debt Refinancing and Redemption Costs In the first quarter of 2021, we made voluntary prepayments of $100 million on our Term Loan B Facility due 2024 and $4.3 million on our Term Loan A Facility due 2024. As a result, we expensed approximately $1.1 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the life of these borrowings.
In the first quarter of 2020, we voluntarily redeemed $100 million of our 6.625% Notes due 2022. As a result, we expensed approximately $0.4 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing, and approximately $1.1 million for an early redemption premium.
Other Income (Expense), Net Other income (expense), net includes the net effect of foreign exchange gains and losses, our proportionate share of earnings from equity in unconsolidated subsidiaries, and all components of net periodic pension and postretirement benefit costs other than service cost. Other income (expense), net was income of $1.2 million in the first quarter of 2021, as compared to expense of $2.3 million in the first quarter of 2020.
At March 31, 2021, we have a cost method investment in an e-mobility company that has announced entry into a merger agreement in an effort to become publicly traded. If the merger is completed and the company becomes publicly traded, the form of our investment would change from a cost method investment to an investment in equity securities that would be measured at fair value. While it is uncertain whether the merger will be completed and the company will become publicly traded, and while the future value of these potential equity securities is unknown should the company become publicly traded, the impact of the change in accounting from cost method to fair value may be significant to our financial statements.
Income Tax Expense Income tax expense was $8.8 million for the three months ended March 31, 2021, as compared to $3.3 million for the three months ended March 31, 2020. Our effective income tax rate was 18.6% in the first quarter of 2021, as compared to (0.7)% in the first quarter of 2020.
During the three months ended March 31, 2020, we recognized a net tax benefit of approximately $7.5 million related to our ability to carry back losses from prior years under the CARES Act. This income tax benefit was the result of our ability to carry back losses to tax years with the higher 35% corporate income tax rate.
Our effective income tax rate for the three months ended March 31, 2021 varies from our effective income tax rate for the three months ended March 31, 2020 primarily as a result of the impact of the goodwill impairment charge recorded during the first quarter of 2020, which had no corresponding income tax benefit. For the three months ended March 31, 2021 and 2020, our effective income tax rates vary from the U.S. federal statutory rate of 21% primarily due to favorable foreign tax rates, the impact of tax credits, and the effect of the goodwill impairment charge in the first quarter of 2020.
Due to the uncertainty associated with the extent and ultimate impact of COVID-19 and the semiconductor shortage on global automotive production volumes, we may experience lower than projected earnings in certain jurisdictions in future periods, and it is reasonably possible that changes in valuation allowances could be recognized in the next twelve months as a result.
Net Income (Loss) Attributable to AAM and Earnings (Loss) Per Share (EPS) Net income (loss) attributable to AAM was income of $38.6 million in the first quarter of 2021, as compared to a loss of $501.3 million in the first quarter of 2020. Diluted earnings per share was $0.33 in the first quarter of 2021, as compared to diluted loss per share of $4.45 in the first quarter of 2020. Net income (loss) attributable to AAM and EPS for the first quarters of 2021 and 2020 were primarily impacted by the factors discussed above.
30

SEGMENT REPORTING
Our business is organized into Driveline and Metal Forming segments, with each representing a reportable segment under ASC 280 Segment Reporting. In the first quarter of 2021, we completed a reorganization of our segments, which included moving certain locations that were previously reported under our Driveline segment to our Metal Forming segment in order to better align our product and process technologies. The amounts in the tables below for the three months ended March 31, 2020 have been retrospectively restated to reflect this reorganization.
The results of each segment are regularly reviewed by the chief operating decision maker to assess the performance of the segment and make decisions regarding the allocation of resources to the segments.
Our product offerings by segment are as follows:
•Driveline products consist primarily of front and rear axles, driveshafts, differential assemblies, clutch modules, balance shaft systems, disconnecting driveline technology, and electric and hybrid driveline products and systems for light trucks, SUVs, crossover vehicles, passenger cars and commercial vehicles; and
•Metal Forming products consist primarily of axle and transmission shafts, ring and pinion gears, differential gears and assemblies, connecting rods and variable valve timing products for Original Equipment Manufacturers and Tier 1 automotive suppliers.
The following table represents sales by reportable segment for the three months ended March 31, 2021 and 2020 (in millions):

| Three Months Ended March 31, |  |  |  |
| 2021 |  | 2020 |  |  |  |  |  |  |  |
Driveline | $ | 1,026.1 |  |  | $ | 945.9 |  |  |  |  |  |  |  |  |

Eliminations | (90.3) |  |  | (84.5) |  |  |  |  |  |  |  |  |
Net Sales | $ | 1,425.1 |  |  | $ | 1,343.5 |  |  |  |  |  |  |  |  |

The change in Driveline sales for the three months ended March 31, 2021, as compared to the three months ended March 31, 2020, primarily reflects increased production volumes as net sales in the first quarter of 2020 were adversely impacted by an estimated $128 million associated with the decline in global automotive production as a result of COVID-19. The change in Driveline sales also reflects an increase of approximately $24 million associated with the effect of metal market pass-throughs to our customers and the impact of foreign exchange related to translation adjustments. These increases were partially offset by a reduction in production volumes on certain vehicle programs that we support as a result of the semiconductor shortage that is impacting the automotive industry, the impact of which we estimate to be approximately $62 million for the first quarter of 2021.
The change in net sales in our Metal Forming segment in the three months ended March 31, 2021, as compared to the three months ended March 31, 2020, primarily reflects increased production volumes as net sales in the first quarter of 2020 were adversely impacted by an estimated $41 million associated with the decline in global automotive production as a result of COVID-19. The change in Metal Forming sales also reflects an increase of approximately $20 million associated with the effect of metal market pass-throughs to our customers and the impact of foreign exchange related to translation adjustments.
We use Segment Adjusted EBITDA as the measure of earnings to assess the performance of each segment and determine the resources to be allocated to the segments. We define EBITDA to be earnings before interest expense, income taxes, depreciation and amortization. Segment Adjusted EBITDA is defined as EBITDA for our reportable segments excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, loss on the sale of a business, impairment charges, pension settlements, and non-recurring items.

For the three months ended March 31, 2021, as compared to the three months ended March 31, 2020, the increase in Segment Adjusted EBITDA for the Driveline segment was primarily attributable to a net increase in production volumes on the vehicle programs that we support, as well as improved operating performance and our continued emphasis on cost management.
The increase in Metal Forming Segment Adjusted EBITDA for the three months ended March 31, 2021, as compared to the three months ended March 31, 2020, was primarily attributable to improved operating performance and the impact of our continued emphasis on cost management.
Reconciliation of Non-GAAP and GAAP Information
In addition to results reported in accordance with accounting principles generally accepted in the United States of America (GAAP) in this MD&A, we have provided certain non-GAAP financial measures such as EBITDA and Total Segment Adjusted EBITDA. Such information is reconciled to its closest GAAP measure in accordance with Securities and Exchange Commission rules below.
We define EBITDA to be earnings before interest expense, income taxes, depreciation and amortization. Total Segment Adjusted EBITDA is defined as EBITDA for our reportable segments excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, loss on the sale of a business, impairment charges, pension settlements, and non-recurring items. We believe that EBITDA and Total Segment Adjusted EBITDA are meaningful measures of performance as they are commonly utilized by management and investors to analyze operating performance and entity valuation. Our management, the investment community and the banking institutions routinely use EBITDA and Total Segment Adjusted EBITDA, together with other measures, to measure our operating performance relative to other Tier 1 automotive suppliers and to assess the relative mix of Adjusted EBITDA by segment. We also believe that Total Segment Adjusted EBITDA is a meaningful measure as it is used for operational planning and decision-making purposes. These non-GAAP financial measures are not and should not be considered a substitute for any GAAP measure. Additionally, non-GAAP financial measures as presented by AAM may not be comparable to similarly titled measures reported by other companies.

LIQUIDITY AND CAPITAL RESOURCES
Our primary liquidity needs are to fund debt service obligations, capital expenditures and working capital requirements, in addition to advancing our strategic initiatives. We believe that operating cash flow, available cash and cash equivalent balances and available borrowing capacity under our Senior Secured Credit Facilities and foreign credit facilities will be sufficient to meet these needs.
At March 31, 2021, we had over $1.5 billion of liquidity consisting of approximately $601 million of cash and cash equivalents, approximately $894 million of available borrowings under our Revolving Credit Facility and approximately $59 million of available borrowings under foreign credit facilities. We have no significant debt maturities before 2024.
Operating Activities In the first three months of 2021, net cash provided by operating activities was $179.1 million as compared to $139.4 million in the first three months of 2020. The following factors impacted cash from operating activities in the first three months of 2021, as compared to the first three months of 2020:
Accounts receivable For the three months ended March 31, 2021, we experienced a decrease in cash flow from operating activities of approximately $78 million related to the change in our accounts receivable balance from December 31, 2020 to March 31, 2021, as compared to the change in our accounts receivable balance from December 31, 2019 to March 31, 2020. This change was primarily attributable to increased sales in March 2021 as sales in March 2020 were negatively impacted due to the onset of COVID-19.
Inventories For the three months ended March 31, 2021, we experienced an increase in cash flow from operating activities of approximately $8 million related to the change in our inventories balance from December 31, 2020 to March 31, 2021, as compared to the change in our inventories balance from December 31, 2019 to March 31, 2020. This change was primarily attributable to increased finished goods inventory at March 31, 2020 as a result of a sharp reduction in sales at the end of the first quarter of 2020 due to the onset of COVID-19.
Accounts payable and accrued expenses For the three months ended March 31, 2021, we experienced an increase in cash flow from operating activities of approximately $63 million related to the change in our accounts payable and accrued expenses balance from December 31, 2020 to March 31, 2021, as compared to the change from December 31, 2019 to March 31, 2020. This change was primarily attributable to increased sales and purchasing activity in March 2021 as this activity was reduced in March 2020 due to the onset of COVID-19 and as a result of the timing of payments to suppliers.
Income taxes Income taxes paid, net was $0.2 million in the first three months of 2021, as compared to $4.2 million in the first three months of 2020. During the first quarter of 2021, we received an income tax refund of approximately $6 million related to the utilization of net operating losses under the provisions of the CARES Act.
Interest paid Interest paid was $43.3 million in the first three months of 2021, as compared to $34.1 million in the first three months of 2020. The increase in interest paid is primarily the result of the timing of semi-annual interest payments on our 6.875% Notes due 2028 that were issued in June 2020.
Malvern Fire In the first three months of 2021, we received $11.4 million of cash as an advance under our insurance policies associated with expenses incurred as a result of the Malvern Fire. At March 31, 2021, we have an insurance recovery receivable of $38.8 million, which is included in Prepaid expenses and other in our Condensed Consolidated Balance Sheet.
Restructuring and acquisition-related costs For the full year 2021, we expect restructuring and acquisition-related payments in cash flows from operating activities to be between $50 million and $65 million, and we expect the timing of cash payments to approximate the timing of charges incurred.
Pension and other postretirement benefits Due to the availability of our pre-funded pension balances (previous contributions in excess of prior required pension contributions), we expect our regulatory pension funding requirements in 2021 to be less than $1 million. We expect our cash payments for other postretirement benefit obligations in 2021, net of GM cost sharing, to be approximately $17 million.
Investing Activities In the first three months of 2021, net cash used in investing activities was $40.4 million as compared to $69.2 million for the three months ended March 31, 2020. Capital expenditures were $39.6 million in the first three months of 2020 as compared to $69.7 million in the first three months of 2020. We expect our capital spending in 2021 to be approximately 4.5% of sales.
33

Financing Activities In the first three months of 2021, net cash used in financing activities was $90.6 million, as compared to net cash provided by financing activities of $87.7 million in the first three months of 2020. The following factors impacted cash from financing activities in the first three months of 2021, as compared to the first three months of 2020:
Senior Secured Credit Facilities Our Senior Secured Credit Facilities, which are comprised of our Revolving Credit Facility, our Term Loan A Facility due 2024, and our Term Loan B Facility due 2024, provide back-up liquidity for our foreign credit facilities. We intend to use the availability of long-term financing under the Senior Secured Credit Facilities to refinance any current maturities related to such debt agreements that are not otherwise refinanced on a long-term basis in their local markets, except where otherwise reclassified to Current portion of long-term debt on our Condensed Consolidated Balance Sheet.
In February 2021, we made a voluntary prepayment of $100 million on our Term Loan B Facility due 2024 and $4.3 million on our Term Loan A Facility due 2024. As a result, we expensed approximately $1.1 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the life of these borrowings.
At March 31, 2021, we had $894.1 million available under the Revolving Credit Facility. This availability reflects a reduction of $30.9 million for standby letters of credit issued against the facility. The borrowings under the Revolving Credit Facility are used for general corporate purposes. See Note 5 - Long-Term Debt for additional information regarding our Senior Secured Credit Facilities.
Subsequent Event In April 2021, we made a voluntary prepayment of $88.8 million on our Term Loan B Facility due 2024. As a result, we expect to expense approximately $0.9 million for a portion of the write-off of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing.
Redemption of 6.625% Notes due 2022 In the first quarter of 2020, we voluntarily redeemed a portion of our 6.625% Notes due 2022. This resulted in a principal payment of $100.0 million and $2.0 million in accrued interest. We expensed approximately $0.4 million for the write-off of a portion of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing, and approximately $1.1 million for the payment of an early redemption premium.
Foreign credit facilities We utilize local currency credit facilities to finance the operations of certain foreign subsidiaries. At March 31, 2021, $109.0 million was outstanding under our foreign credit facilities, as compared to $88.8 million at December 31, 2020. At March 31, 2021, an additional $58.6 million was available under our foreign credit facilities.
Treasury stock Treasury stock increased by $4.0 million in the first three months of 2021 to $216.0 million as compared to $212.0 million at year-end 2020, due to the withholding and repurchase of shares of AAM stock to satisfy employee tax withholding obligations due upon the vesting of performance shares and restricted stock units.
Subsidiary Guarantees of Registered Debt Securities Our 6.875% Notes, 6.50% Notes, 6.25% Notes (due 2026), and 6.25% Notes (due 2025) (collectively, the Notes) are senior unsecured obligations of AAM, Inc. (Issuer); all of which are fully and unconditionally guaranteed, on a joint and several basis, by Holdings and substantially all domestic subsidiaries of AAM, Inc. and MPG Inc (Subsidiary Guarantors). Holdings has no significant assets other than its 100% ownership in AAM, Inc. and MPG Inc., and no direct subsidiaries other than AAM, Inc. and MPG Inc.
Each guarantee by Holdings and/or any of the Subsidiary Guarantors is:
•a senior obligation of the relevant Subsidiary Guarantors;
•the unsecured and unsubordinated obligation of the relevant Subsidiary Guarantors; and
•of equal rank with all other existing and future unsubordinated and unsecured indebtedness of the relevant Subsidiary Guarantors.
34

Each guarantee by a Subsidiary Guarantor provides by its terms that it will be automatically, fully and unconditionally released and discharged upon:
•Any sale, exchange or transfer (by merger or otherwise) of the capital stock of such Subsidiary Guarantor, or the sale or disposition of all the assets of such Subsidiary Guarantor, which sale, exchange, transfer or disposition is made in compliance with the applicable provisions of the indentures;
•the exercise by the issuer of its legal defeasance option or covenant defeasance option or the discharge of the issuer’s obligations under the indentures in accordance with the terms of the indentures; or
•the election of the issuer to affect such a release following the date that such guaranteed Notes have an investment grade rating from both Standard & Poor's Ratings Group, Inc, and Moody's Investors Service, Inc.
The following represents summarized financial information of AAM Holdings, AAM Inc. and the Subsidiary Guarantors (collectively, the Combined Entities). The information has been prepared on a combined basis and excludes any investments of AAM Holdings, AAM Inc., or the Subsidiary Guarantors in non-guarantor subsidiaries. Intercompany transactions and amounts between Combined Entities have been eliminated.

CYCLICALITY AND SEASONALITY
Our operations are cyclical because they are directly related to worldwide automotive production, which is itself cyclical and dependent on general economic conditions and other factors. Typically, our business is also moderately seasonal as our major OEM customers historically have an extended shutdown of operations (normally 1-2 weeks) in conjunction with their model year changeover and an approximate one-week shutdown in December. Our major OEM customers also occasionally have longer shutdowns of operations (up to six weeks) for program changeovers. Accordingly, our quarterly results may reflect these trends.
LITIGATION AND ENVIRONMENTAL MATTERS
We are involved in, or potentially subject to, various legal proceedings or claims incidental to our business. These include, but are not limited to, matters arising out of product warranties, tax or contractual matters, and environmental obligations. Although the outcome of these matters cannot be predicted with certainty, at this time we do not believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows.
We are subject to various federal, state, local and foreign environmental and occupational safety and health laws, regulations and ordinances, including those regulating air emissions, water discharge, waste management and environmental cleanup. We will continue to closely monitor our environmental conditions to ensure that we are in compliance with all laws, regulations and ordinances. We have made, and anticipate continuing to make, capital and other expenditures (including recurring administrative costs) to comply with environmental requirements at our current and former facilities. Such expenditures were not significant in the first quarter of 2021.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
MARKET RISK
Our business and financial results are affected by fluctuations in global financial markets, including currency exchange rates and interest rates. Our hedging policy has been developed to manage these risks to an acceptable level based on management’s judgment of the appropriate trade-off between risk, opportunity and cost. We do not hold financial instruments for trading or speculative purposes.
Currency Exchange Risk From time to time, we use foreign currency forward contracts to reduce the effects of fluctuations in exchange rates relating to certain foreign currencies. At March 31, 2021 and December 31, 2020, we had currency forward contracts with a notional amount of $171.3 million and 178.2 million outstanding, respectively. The potential decrease in fair value of foreign exchange contracts, assuming a 10% adverse change in the foreign currency exchange rates, would be approximately $15.6 million at March 31, 2021 and was approximately $16.2 million at December 31, 2020.
In 2019, we entered into a fixed-to-fixed cross-currency swap to reduce the variability of functional currency equivalent cash flows associated with changes in exchange rates on certain Euro-based intercompany loans. In the first quarter of 2020, we discontinued this cross-currency swap, which was in an asset position of $9.8 million on the date that it was discontinued. Also in the first quarter of 2020, we entered into a new fixed-to-fixed cross-currency swap to reduce the variability of functional currency equivalent cash flows associated with changes in exchange rates on certain Euro-based intercompany loans. At March 31, 2021 and December 31, 2020, the notional amount of the fixed-to-fixed cross-currency swap was $234.6 million and $244.2 million, respectively. The potential decrease in fair value of the fixed-to-fixed cross-currency swap, assuming a 10% adverse change in the foreign currency exchange rates, would be approximately $23.5 million at March 31, 2021 and was approximately $24.4 million at December 31, 2020.
Future business operations and opportunities, including the expansion of our business outside North America, may further increase the risk that cash flows resulting from these global operations may be adversely affected by changes in currency exchange rates. If and when appropriate, we intend to manage these risks by creating natural hedges in the structure of our global operations, utilizing local currency funding of these expansions and various types of foreign exchange contracts.
Interest Rate Risk We are exposed to variable interest rates on certain credit facilities. From time to time, we have used interest rate hedging to reduce the effects of fluctuations in market interest rates. In 2019, we entered into a variable-to-fixed interest rate swap to reduce the variability of cash flows associated with interest payments on our variable rate debt. At March 31, 2021, we have the following notional amounts hedged in relation to our variable-to-fixed interest rate swap: $900.0 million
36

through May 2021, $750.0 million through May 2022, $600.0 million through May 2023 and $500.0 million through May 2024.
The pre-tax earnings and cash flow impact of a one-percentage-point increase in interest rates (approximately 17% of our weighted-average interest rate at March 31, 2021) on our long-term debt outstanding, would be approximately $5.1 million at March 31, 2021 and was approximately $6.0 million at December 31, 2020, on an annualized basis.
Item 4. Controls and Procedures
Disclosure Controls and Procedures
Under the direction of our Chief Executive Officer and Chief Financial Officer, we evaluated our disclosure controls and procedures and internal control over financial reporting and concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) were effective as of March 31, 2021.
Changes in Internal Control over Financial Reporting
On January 1, 2019, we began the implementation of our global enterprise resource planning (ERP) systems at certain of the locations that were acquired as part of the MPG acquisition. As part of these implementations, we have modified the design and documentation of our internal control processes and procedures, where appropriate. We will continue to implement these ERP systems at certain locations throughout 2021.
As a result of temporarily closing certain of our global facilities due to the impact of COVID-19, a significant number of our associates have continued to work remotely during the first quarter of 2021. This has not had a material effect on our internal control over financial reporting as we have maintained our existing controls and procedures over financial reporting during this period.
Except as described above with regard to implementation of ERP systems at certain legacy MPG locations, there were no changes in our internal control over financial reporting during the quarter ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
