Item 1A. Risk Factors

In addition to other information set forth in this report and the risk factor noted below, you should consider other risk factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, which could materially affect our business, financial condition or future results. Other than noted below, there have been no material changes to our risks described in our 2020 Annual Report on Form 10-K or the "CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING INFORMATION" in this Quarterly report are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently judge to be immaterial also may materially adversely affect our business, financial condition or operating results.

GOVERNMENT REGULATION

We are conducting a formal internal review of our emission certification process and compliance with emission standards with respect to our pick-up truck applications and are working with the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) to address their questions about these applications. Due to the continuing nature of our formal internal review and on-going discussions with EPA and CARB, we cannot predict the final results of this formal review and these regulatory processes, nor whether, or the extent to which, they could have a material adverse impact on our results of operations and cash flows.

We previously announced that we are conducting a formal internal review of our emissions certification process and compliance with emission standards with respect to all of our pick-up truck applications, following conversations with the EPA and CARB regarding certification of our engines for model year 2019 RAM 2500 and 3500 trucks. During conversations with the EPA and CARB about the effectiveness of our pick-up truck applications, the regulators raised concerns that certain aspects of our emissions systems may reduce the effectiveness of our emissions control systems and thereby act as defeat devices. As a result, our internal review focuses, in part, on the regulators’ concerns. We are working closely with the regulators to enhance our emissions systems to improve the effectiveness of all of our pick-up truck applications and to fully address the regulators’ requirements. Based on discussions with the regulators, we have developed a new calibration for the engines in model year 2019 RAM 2500 and 3500 trucks that has been included in all engines shipped since September 2019. During our discussions, the regulators turned their attention to other model years and other engines, most notably our pick-up truck applications for RAM 2500 and 3500 trucks for model years 2013 through 2018. We will continue to work together closely with the relevant regulators to develop and implement recommendations for improvement as part of our ongoing commitment to compliance.

Due to the continuing nature of the formal review, our ongoing cooperation with the regulators and the presence of many unknown facts and circumstances, we are not yet able to estimate the financial impact of these matters. It is possible that the consequences of any remediation plans resulting from our formal review and these regulatory processes could have a material adverse impact on our results of operations and cash flows.

The U.S. government’s pending rules and regulations concerning mandatory COVID-19 vaccination of U.S.-based employees of companies that work on or in support of federal contracts, or have 100 or more employees, could materially and adversely affect our results of operations, financial condition and cash flows.

On September 9, 2021, President Biden issued an executive order requiring all employers with U.S. government contracts to ensure that their U.S.-based employees, contractors and subcontractors, that work on or in support of U.S. government contracts, are fully vaccinated against COVID-19 as required by the executive order. The executive order includes on-site and remote U.S.-based employees, contractors and subcontractors and provides for limited medical and religious exceptions.

In addition, on September 9, 2021, President Biden announced that he has directed Occupational Safety and Health Administration (OSHA) to develop an Emergency Temporary Standard (ETS) mandating either the full vaccination against COVID-19 or weekly testing of employees for employers with 100 or more employees. OSHA has not yet issued the ETS nor provided any additional information on its contents or requirements.

It is currently not possible to predict with certainty the impact the executive order or the OSHA ETS will have on our workforce. As a U.S. government contractor, all U.S. based employees, contractors and subcontractors that service or support our U.S. government contracts, which are subject to the provisions of the executive order, will be required to be fully vaccinated against COVID-19. Employees who are not subject to this requirement and who are not fully vaccinated may be subject to the ETS that will require them to get a COVID-19 test at least once a week. Additional vaccine mandates may be announced in jurisdictions in which our businesses operate. Our implementation of these requirements may result in attrition, including attrition of critically skilled labor, and difficulty securing future labor needs, which could materially and adversely affect our results of operations, financial condition and cash flows.

ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds

The following information is provided pursuant to Item 703 of Regulation S-K:

In December 2019, the Board authorized the acquisition of up to $2.0 billion of additional common stock upon completion of the 2018 repurchase plan. During the three months ended October 3, 2021, we repurchased $138 million of common stock under the 2019 authorization. The dollar value remaining available for future purchases under the 2019 program at October 3, 2021, was $766 million.

Our Key Employee Stock Investment Plan allows certain employees, other than officers, to purchase shares of common stock on an installment basis up to an established credit limit. We hold participants’ shares as security for the loans and would, in effect, repurchase shares only if the participant defaulted in repayment of the loan. Shares associated with participants' sales are sold as open-market transactions via a third-party broker.

ITEM 3. Defaults Upon Senior Securities

ITEM 4. Mine Safety Disclosures
