The total agreement is valued at $804.0 million with the U.S. Air Force investing two-thirds of the funding requiredinternal-use software guidance in order to complete development of the AR1 engine by 2019. The work is expecteddetermine which implementation costs to be completed no later than December 31, 2019. The U.S. Air Force has obligated $174.0 million with Aerojet Rocketdyne contributing $77.7 milliondefer and ULA contributing $5.8 million in cash and $3.5 million in "in-kind" R&D expense. The total potential U.S. government investment, including all options, is $536.0 million. The total potential investment by Aerojet Rocketdyne and its partners, including all options, is $268.0 million. Under the terms of the AR1 agreement, the U.S. Air Force contributions are recognized proportionatelyrecognize as an offsetasset. The Company adopted this new standard as of January 1, 2020, on a prospective basis and the adoption of this guidance did not have a material impact on the Company's financial position, results of operations, or cash flows.

Dueservices to, the nature ofCompany’s customers, including the programs, developingU.S. government and major aerospace and defense prime contractors.
The Company evaluates the estimated total contract revenuevalue and cost estimates for performance obligations at completion requires the use of significant judgment. Estimates are continually evaluated as work progressesleast quarterly and are revised as necessary.more frequently when circumstances significantly change. Factors that must be considered in estimating the work to be completed include, but are not limited to: labor productivity, the nature and technical complexity of the work to be performed, availability and cost volatility of materials, subcontractor and vendor performance, warranty costs, volume assumptions, anticipated labor agreements, inflationary trends, schedule and performance delays, availability of funding from the customer, and the recoverability of costs incurred outside the original contract included in any estimates to complete. TheWhen the Company’s estimate of total costs to be incurred to satisfy a performance obligation exceeds the expected revenue, the Company reviews contract performance and cost estimates for some contracts at least monthly and for others at least quarterly and more frequently when circumstances significantly change.recognizes the loss immediately. When the Company determines that a change in estimate is determined to haveestimates has an impact on contractthe associated profit of a performance obligation, the Company will record arecords the cumulative positive or negative adjustment to the statement of operations. Changes in estimates and assumptions related to the status of certain long-term contracts may have a material effect on the Company’s operating results.

Recently Adopted Accounting Pronouncements
In August 2014,Net contract liabilities decreased by $28.5 million primarily due to an increase in unbilled receivables as of March 31, 2020. During the Financial Accounting Standards Board (“FASB”) issued an amendment tothree months ended March 31, 2020, the accounting guidance related toCompany recognized sales of $109.3 million that were included in the evaluation of an entity's ability to continue as a going concern. The amendment establishes management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern in connection with preparing financial statements for each annual and interim reporting period. The update also gives guidance to determine whether to disclose information about relevant conditions and events when there is substantial doubt about an entity’s ability to continue as a going concern. The Company adopted this guidanceCompany's contract liabilities as of December 31, 20162019.
As of March 31, 2020, the Company’s total remaining performance obligations, also referred to as backlog, totaled $5.2 billion. The Company expects to recognize approximately 38%, or $2.0 billion, of the remaining performance obligations as sales over the next twelve months, an additional 24% the following twelve months, and no additional information was required to be presented38% thereafter.
The Company's contracts are largely categorized as either "fixed-price" (largely used by the U.S. government for production-type contracts) or "cost-reimbursable" (largely used by the U.S. government for development-type contracts). Fixed-price contracts present the risk of unreimbursed cost overruns, potentially resulting in lower than expected contract profits and margins. This risk is generally lower for cost-reimbursable contracts which, as a result, generally have a lower margin. The following table summarizes the percentages of net sales by contract type:

The Company's Real Estate segment represented less than 1% of the adoption. As the accounting standard only impacted presentation, the new standard did not have an impact on the Company's financial position, results of operations, or cash flows.
In November 2015, the FASB issued guidance that requires deferred tax liabilities and assets to be classified as noncurrent in the consolidated balance sheet. The standard is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for financial statements that have not been previously issued. The Company adopted this guidance retrospectively to all periods presented as of December 31, 2016, which resulted in $36.5 million of current deferred income taxes as of December 31, 2015, being reclassified as noncurrent. As the accounting standard only impacted presentation, the new standard did not have an impact on the Company's financial position, results of operations, or cash flows.
In March 2016, the FASB amended the existing accounting guidance related to stock compensation. The amendment requires all income tax effects of awards to be recognized in the income statement when awards vest and allows a choice to account for forfeitures on an estimated or actual basis. There is also a requirement to present excess income tax benefits as an operating activity on the statement of cash flows. Effective January 1, 2017, the Company adopted the amendment requiring recognition of excess tax benefits and tax deficiencies in the income statement prospectively and the impact to the consolidated statement of operations for the first quarter of fiscal 2017. In addition, the Company elected to change its accounting policy to account for forfeitures when they occur for consistency with the U.S. government recovery accounting practices on a modified retrospective basis. The Company also elected to adopt the amendment related to the presentation of excess tax benefits within operating activities on the statement of cash flows, retrospectively.
Recently Issued Accounting Pronouncements
In May 2014, the FASB amended the existing accounting standards for revenue recognition. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an


amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The effective date of the new standard is for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company plans to adopt the guidance during the first quarter of fiscal 2018, retrospectively with the cumulative effect recognized during that quarter (modified retrospective basis). The Company has developed a comprehensive implementation plan across all segments that include evaluating the impact of the new guidance on existing contracts, and updating impacted accounting policies, processes, controls and systems. The Company expects the primary impact of the new guidance will be a change in the timing of when revenue is recognized on certain fixed price and cost reimbursable type contracts. The new guidance prescribes that an entity recognizes revenue when (or as) it satisfies a performance obligation by transferring a promised good or service to a customer. A good or service is transferred when (or as) the customer obtains control of that asset. Under this new guidance, the Company expects to discontinue the use of the unit-of-delivery method on certain customer contracts and remeasure progress toward completion using the cost-to-cost method. The unit-of-delivery method totaled 44% of net sales for the first ninethree months of fiscal 2017. The Company expects the adoption of this new standard will have a material impact on net sales recognized in any given fiscal yearended March 31, 2020 and a material impact on the amount reported for contract backlog. The adoption will also result in the reclassification of contract related assets on the consolidated balance sheet.2019.
In February 2016, the FASB issued guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The effective date of the new standard is for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements.
In August 2016, the FASB issued an amendment to the accounting guidance related to classification of certain cash receipts and cash payments in the statement of cash flows. The standard provides guidance for eight targeted changes with respect to how cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. The standard is effective for financial statements issued for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements.
In January 2017, the FASB issued an amendment to the accounting guidance related to goodwill impairment. The update eliminates "Step 2" which involves determining the implied fair value of goodwill and comparing it to the carrying amount of goodwill to measure the goodwill impairment loss, if any. The quantitative assessment "Step 1" will be used to determine both the existence and amount of goodwill impairment. The standard should be applied on a prospective basis and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted. The Company plans to adopt this new accounting guidance in conjunction with its annual impairment test on October 1, 2017. The Company does not expect the adoption to have a significant impact on its consolidated financial statements.
In March 2017, the FASB amended the existing accounting guidance relating to the presentation of net periodic pension cost and net periodic postretirement benefit cost ( the “NPPC”) in the income statement.  The amended guidance requires the service cost component to be presented in the same line item or items as other compensation arising from the services rendered by the pertinent employees during the period, and other components of the NPPC to be presented in the statement of operations separately from service cost components and outside a subtotal of income from operations.   If a separate line item or items are used to present the other components of the NPPC, that line item or items must be appropriately described.  If a separate line item or items are not used,  the line item or items used in the statement of operations to present the other components of NPPC must be disclosed. The new guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued. The Company is evaluating the impact of adopting this new accounting standard on its consolidated financial statements.

j. Redeemable Commong. Treasury Stock
On May 30, 2017,During the three months ended March 31, 2020, the Company made a registered rescission offer to buy back unregistered shares from eligible Plan participants at the original purchase price plus interest, or to reimburse eligible Plan participants for losses they may have incurred if their shares had been sold. The registered rescission offer expired on June 30, 2017, and settlement payments of $3.5repurchased less than 0.1 million under the offer were completed in the third quarter of fiscal 2017 (see Note 13).
The Company inadvertently failed to register with the Securities Exchange Commission ("SEC") the issuance of certain of its common shares at a cost of $0.5 million. The Company reflects stock repurchases in its defined contribution 401(k) employee benefit plan (the “Plan”). Asfinancial statements on a result, certain Plan participants who purchased such securities pursuant to the Plan may have had the right to rescind certain of their purchases for consideration equal to the purchase price paid for the securities (or if such security has been sold, to receive consideration with respect to any loss incurred on such sale) plus interest from the date of purchase. In June 2008, the Company filed a registration statement on Form S-8 to register future transactions in the Company's stock fund in the Plan."settlement" basis.
Note 5. Acquisition
On February 24, 2017, the Company closed on an agreement to purchase substantially all of the assets of Coleman Aerospace, a systems engineering and integration provider, from L3 Technologies, Inc. ("L3"). Coleman Aerospace operates now as a subsidiary of Aerojet Rocketdyne, Inc. and was renamed Aerojet Rocketdyne Coleman Aerospace, Inc. ("Coleman"). The acquisition builds upon and expands the Company’s capabilities in mission analysis and systems engineering, and increases its product portfolio to include vehicle integration for small-, medium- and intermediate-range ballistic missile targets and other small launch vehicles.
The aggregate consideration paid to L3 for the purchase of Coleman was $17.0 million, which included $15.0 million of cash paid at closing and a $2.0 million working capital adjustment paid in the third quarter of fiscal 2017. The Company incurred $1.0 million of expenses related to the acquisition of Coleman.
The preliminary purchase price allocation has been developed based on preliminary estimates of the fair value of the assets and liabilities of Coleman that the Company acquired. In addition, the allocation of the preliminary purchase price to acquired intangible assets is based on preliminary fair value estimates.

The purchase price allocation resulted in the recognition of $1.9 million in goodwill, all of which is deductible for tax purposes and included within the Company’s Aerospace and Defense segment. Goodwill recognized from the acquisition primarily relates to the expected contributions of Coleman to the Company’s overall corporate strategy.

In the first ninethree months of fiscal 2017,ended March 31, 2020, the income tax provision was at$11.3 million for an effective tax rate less thanof 26.5%. The Company’s effective tax rate differed from the 21% statutory federal statutoryincome tax rate primarily due to state income taxes and certain expenditures which are permanently not deductible for tax benefits attributable topurposes, partially offset by the expirationimpact of the statute of limitations, excess tax benefits from the exerciseResearch and vesting of stock-based compensation, and the revisions of estimated tax balances based on expected tax filings.Development ("R&D") credits.

A valuation allowance is required when it is more-likely-than-not that all or a portion of deferred tax assets may not be realized. Assessing the need for a valuation allowance requires management to evaluate, on a quarterly basis, all available evidence, both positive and negative. As of September 30, 2017,March 31, 2020, the Company continues to believe that the weight of the positive evidence outweighed the negative evidence regarding the realization of its net deferred tax assets.
In the next twelve months, the Company believes it is reasonably possible that the unrecognized tax benefits could decrease by approximately $23.9 million as a result of the resolution of certain outstanding positions.
In the second quarter of fiscal 2017, the Company received a refund of $21.3 million from the Internal Revenue Service associated with federal taxes on deposit.

Note 8. Commitments and Contingencies
a. Capital Lease Commitments
In September 2017, the Company entered into an agreement to lease 122,000-square feet of office space in Huntsville, Alabama. The term of the lease is twenty years and is expected to commence in March 2018 resulting in an estimated financial commitment of $48.8 million representing a present value of $25.1 million. The lease obligation over the next five fiscal years is as follows: zero in fiscal 2017, $1.2 million in fiscal 2018, and approximately $2.0 million each year for fiscal 2019 through fiscal 2021.
In October 2017, the Company entered into an agreement to lease a new 136,000-square-foot advanced manufacturing facility located in Huntsville, Alabama.

b. Legal Matters
The Company and its subsidiaries are subject to legal proceedings, including litigation in U.S. federal and state courts, which arise out of, and are incidental to, the ordinary course of the Company’s on-going and historical businesses. The Company is also subject from time to time to suits under the U.S. federal False Claims Act, known as “qui tam” actions, and to governmental investigations by federal and state agencies. The Company cannot predict the outcome of such proceedings with any degree of certainty. Loss contingency provisions are recorded for probable losses at management’s best estimate of a loss, or whenloss. When only a best estimate cannotrange of amounts can be made, a minimum loss contingencyreasonably estimated and no amount within the range is more likely than another, the low end of the range is recorded. These estimates are often initially developed substantially earlier than when the ultimate loss is known, and are refined each quarterly reporting period as additional information becomes available. For legal settlements where the cash payments are fixed and determinable, the Company will estimate an interest factor and discount the liability accordingly.
Asbestos Litigation
The Company has been, and continues to be, named as a defendant in lawsuits alleging personal injury or death and seeking various monetary damages due to exposure to asbestos in building materials, products, or in manufacturing operations. The majority of cases are pending in Texas and Illinois.Illinois state courts. There were 6364 asbestos cases pending as of September 30, 2017.March 31, 2020.
Given the lack of any significant consistency to claims (i.e., as to product, operational site, or other relevant assertions) filed against the Company, the Company is generally unable to make a reasonable estimate of the future costs of pending


claims or unasserted claims.The aggregate settlement costs and legal and administrative fees associated with the Company’s asbestos litigation has been immaterial for the last three years. As of September 30, 2017,March 31, 2020, the Company has accrued an immaterial amount related to pending claims.
Inflective, Inc. (“Inflective”) Litigation
On December 18, 2014, Inflective filed a complaint against Aerojet Rocketdyne and Kathleen E. Redd, individually, in the Superior Court of the State of California, Sacramento County, Inflective, Inc. v Aerojet Rocketdyne, Inc., Kathleen E. Redd, et al, Case No. 34-2014-00173068. Inflective asserted in the complaint causes for breach of contract, breach of implied contract, false promise, inducing breach of contract, intentional interference with contractual relations, negligent interference with prospective economic relations, and intentional interference with prospective economic relations and sought compensatory damages in excess of $3.0 million, punitive damages, interest and attorney’s costs. The complaint arose out of the Company’s implementation of ProjectOne, a company-wide enterprise resource planning (“ERP”) system, for which Inflective had been a consultant to the Company. After a series of motions and demurrers over nearly two years in which the Court dismissed the claims against Ms. Redd and certain claims against the Company, the Company entered into a settlement of the litigation with Inflective during the second quarter of fiscal 2017 and the case was dismissed with prejudice. The terms of the settlement are not material to the Company’s financial statements. 
Separately, Satish Rachaiah, a former consultant on ProjectOne (working for Inflective), attempted to intervene in the action and assert claims against Aerojet Rocketdyne arising out of Aerojet Rocketdyne’s alleged interference with his employment with Inflective.  Aerojet Rocketdyne opposed intervention, and the Court ultimately denied Mr. Rachaiah’s motion to intervene.  On December 30, 2015, Rachaiah filed a separate lawsuit in the Superior Court of the State of California, Sacramento County, Satish Rachaiah v. Aerojet Rocketdyne, Inc., Case No. 34-2015-00188516. The Company received the complaint on April 7, 2016, and an amended complaint was served on June 17, 2016.  Rachaiah asserted the same claims in the complaint as attempted when he tried to intervene.  On June 3, 2016, the Court granted Rachaiah’s motion to consolidate the case with the Inflective litigation, finding that the two cases involve common parties, witnesses, legal issues and facts.  Aerojet Rocketdyne filed a demurrer to Rachaiah’s first amended complaint on July 22, 2016.  On September 26, 2016, the Court granted the demurrer in part and overruled it in part, dismissing the plaintiff’s claims for intentional and negligent interference with prospective economic relations with leave to amend.  On October 6, 2016, Rachaiah filed a second amended complaint, once again asserting claims for intentional and negligent interference with prospective economic relations. Aerojet


Rocketdyne filed its answer to the second amended complaint on November 11, 2016. Discovery is in process. No liability for the Rachaiah matter has been recorded by the Company as of September 30, 2017.

The complaint allegesalleged causes of action against the Company based on negligencefalse claims, retaliation, and negligence per se, strict liability,wrongful termination of employment seeking injunctive relief, civil penalties, and willful, reckless and wanton conduct against Aerojet Rocketdyne, and seeks unspecified compensatory and punitive damages. In February 2019, the Company filed a Motion to Dismiss the False Claims Act ("FCA") counts of the complaint and a Motion to Compel Arbitration on the employment based claims. In May 2019, the court dismissed one count of the FCA claim, denied the motion to dismiss the remaining FCA counts, and moved the employment based claims to arbitration. The Company continues to vigorously contest the complaint’s allegations and has filed its answer and discovery has commenced. Trial is scheduled for February 5, 2018. Nonot recorded any liability for this matter has been recorded by the Company as of September 30, 2017.March 31, 2020.
Occupational Safety
On January 16, 2015, the Company received a notice that the State of California, Division of Occupational Safety & Health (“Cal\OSHA”), Bureau of Investigation (“BOI”) is conducting an investigation into an accident that occurred at the Rancho Cordova facility in November 2013.  The accident involved the deflagration of solid rocket propellant following a remote cutting operation and resulted in injuries to two employees, one of whom ultimately died from his injuries. Cal\OSHA issued nine citations relating to the accident with penalties of approximately $0.1 million, all of which the Company has appealed. The BOI is the criminal investigatory arm of Cal\OSHA and is required by law to investigate any occupational fatality to determine if criminal charges will be recommended. In August 2016, the BOI advised that it had completed its investigation and the criminal aspect of the case was closed. Pre-hearing conferences on the Company’s appeal of the citations were held on May 22, 2017 and September 11, 2017.  The judge will likely set a hearing date for early 2018.
Department of Justice("DOJ") Investigation
The Company is responding to a civil investigative demand issued by the DOJ in the first quarter of fiscal 2017 requesting information relating to allegations under the False Claims Act that the Company may have previously made false representations to the U.S. government regarding the Company’s compliance with certain regulatory cybersecurity requirements.  The Company is cooperating with the DOJ in its investigation of the false claim allegations.
c.b. Environmental Matters
The Company is involved in approximately forty40 environmental matters under the Comprehensive Environmental Response Compensation and Liability Act, the Resource Conservation Recovery Act, and other federal, state, local, and foreignlocal laws relating to soil and groundwater contamination, hazardous waste management activities, and other environmental matters at some of its current and former facilities. The Company is also involved in a number of remedial activities at third party sites, not owned by the Company, where it is designated a potentially responsible party (“PRP”("PRP") by either the U.S. Environmental Protection Agency ("EPA") and/or a state agency. In many of these matters, the Company is involved with other PRPs. In some instances, the Company’s liability and proportionate share of costs have not been determined largely due to uncertainties as to the nature and extent of site conditions and the Company’s involvement. While government agencies frequently claim PRPs are jointly and severally liable at such sites, in the Company’s experience, interim and final allocations of liability and costs are generally made based on relative contributions of waste or contamination. Anticipated costs associated with environmental remediation that are probable and estimable are accrued. In cases where a date to complete remedial activities at a particular site cannot be determined by reference to agreements or otherwise, the Company projects costs over an appropriate time period not exceeding fifteen15 years. In such cases, generally the Company does not have the ability to reasonably estimate environmental remediation costs that are beyond this period. Factors that could result in changes to the Company’s estimates include completion of current and future soil and groundwater investigations, new claims, future agency demands, discovery of more or less contamination than expected, discovery of new contaminants, modification of planned remedial actions, changes in estimated time required to remediate, new technologies, and changes in laws and regulations.
As of September 30, 2017,March 31, 2020, the aggregate range of these anticipated environmental costs was $334.4$302.6 million to $496.4$453.7 million and the accrued amount was $334.4$302.6 million. See Note 8(d)8(c) for a summary of the environmental reserve activity. Of these accrued liabilities, approximately 99% relates to the Company’s U.S. government contracting business, and a portion of this liability is recoverable. The significant environmental sites are discussed below. The balance of the accrued liabilities, which are not recoverable from the U.S. government, relate to other sites for which the Company’s obligations are probable and estimable.
Sacramento, California Site


In 1989, a federal district court in California approved a Partial Consent Decree (“PCD”("PCD") requiring Aerojet Rocketdyne, among other things, to conduct a Remedial Investigation and Feasibility Study to determine the nature and extent of impacts due to the release of chemicals from the Sacramento, California site, monitor the American River and offsite public water supply wells, operate Groundwater Extraction and Treatment facilities that collect groundwater at the site perimeter, and pay certain government oversight costs. The primary chemicals of concern for both on-site and off-site groundwater are trichloroethylene, perchlorate, and n-nitrosodimethylamine. The PCD has been revised several times, most recently in 2002. TheA 2002 PCD revision (a) separated the Sacramento site into multiple operable units to allow quicker implementation of remedyremedies for critical areas; (b) required the Company to guarantee up to $75$75 million (in addition to a prior $20 million guarantee) to assure that Aerojet Rocketdyne’s Sacramento remediation activities are fully funded; and (c) removed approximately 2,600 acres of non-contaminated land from the EPA superfund designation.
Aerojet Rocketdyne is involved in various stages of soil and groundwater investigation, remedy selection, design, construction, operation and remedy constructionmaintenance associated with the operable units. In 2002,units, all of which are conducted under the direction and oversight of the EPA, issued a Unilateral Administrative Order (“UAO”) requiring Aerojet Rocketdyne to implement the EPA-approved remedial action in the Western Groundwater Operable Unit. An identical order was issued byincluding unilateral administrative orders, and the California Department of Toxic Substances Control ("DTSC") and Regional Water Quality Control Board, Central Valley (“Central Valley RWQCB”Region ("RWQCB"). On July 7, 2011, the EPA issued Aerojet Rocketdyne its Approval of Remedial Action Construction Completion Report for Western Groundwater Operable Unit and its Determination of Remedy as Operational and Functional. On September 20, 2011, the EPA issued two UAOs to Aerojet Rocketdyne to complete a remedial design and implement remedial action for the Perimeter Groundwater Operable Unit. One UAO addresses groundwater and the other addresses soils within the Perimeter Groundwater Operable Unit. Issuance of the UAOs is the next step in the superfund process for the Perimeter Groundwater Operable Unit. Aerojet Rocketdyne submitted a final Remedial Investigation Report for the Boundary Operable Unit in 2010 and a revised Feasibility Study for the Boundary Operable Unit in 2012. A Record of Decision was issued by the EPA on August 4, 2015. Aerojet Rocketdyne anticipates the EPA will issue a UAO or negotiate a consent decree for implementation of the remedy. A draft Remedial Investigation Report for the Island Operable Unit was submitted in January 2013 and the Final Remedial Investigation Report was issued on September 3, 2015. A portion of the Island Operable Unit, Area 40, is being handled separately and Aerojet Rocketdyne submitted a draft Feasibility Study to the agencies on June 23, 2016. The remaining operable units are under various stages of investigation. On September 22, 2016, the EPA completed its first five-year remedy review of the Sacramento superfund site. The five-year review required by statute and regulation applies to all remedial actions which result in hazardous substances above levels that allow unlimited use and unrestricted exposure. The Company is working with the EPA to address the findings of the five-year remedy review.
Following completion of the five-year review, the EPA required Aerojet Rocketdyne to conduct a vapor intrusion evaluation of several of its Sacramento facility buildings, and off-site businesses and residences.  The evaluation was conducted to determine whether and to what extent volatile organic compounds, such as trichloroethylene, may be present in indoor air or in soil at concentrations that exceed EPA thresholds that would require some type of mitigation. Sample results in two buildings resulted in short-term responses, including efforts to increase air flow and prevent vapors from entering the buildings.  Off-site soil gas sampling did not identify trichloroethylene concentrations that warranted indoor air monitoring of residences or commercial buildings.  A second phase of indoor air sampling which includes resampling a subset of the on-site buildings sampled in the first phase and off-site soil gas sampling, as determined by EPA, began in September 2017.
The entire southern portion of the site known as Rio Del Oro was under state orders issued in the 1990s from the Department of Toxic Substances Control (“DTSC”) to investigateDTSC and remediate environmental contamination in the soils and the Central Valley RWQCB to investigate and remediate soil and groundwater environmental contamination. On March 14,In 2008, the DTSC released all but approximately 400 acres of the Rio Del Oro property from DTSC’s environmental orders regarding soil contamination. Aerojet Rocketdyne expectscontamination although the approximately 400 acres of Rio Del Oro property that remain subject to the DTSC orders to be released once the soil remediation has been completed. The Rio Del Oro property remains subject to the Central Valley RWQCB’s orders to investigate and remediate groundwater environmental contamination emanating offsite from such property. Pursuant to a settlement agreement entered into in 2009, Aerojet Rocketdyne and The Boeing Company ("Boeing") have defined responsibilities with respect to future costs and environmental projects relating to this property.the property
As of September 30, 2017,March 31, 2020, the estimated range of anticipated costs discussed above for the Sacramento, California site was $202.3$204.2 million to $320.3$327.4 million and the accrued amount was $202.3$204.2 million included as a component of the Company’s


environmental reserves. Expenditures associated with this matter are partially recoverable. See Note 8(d) below8(c) for further discussion on recoverability.
Baldwin Park Operable Unit (“BPOU”("BPOU")
As a result of its former Azusa, California operations, in 1994, Aerojet Rocketdyne was named a PRP by the EPA in the area of the San Gabriel Valley Basin superfund site known as the BPOU. Between 1995 and 1997, the EPA issued Special Notice Letters to Aerojet Rocketdyne and eighteen other companies requesting that they implement a groundwater remedy. On June 30, 2000, the EPA issued a UAO ordering the PRPs to implement a remedy consistent with the 1994 record of decision.In 2002, Aerojet Rocketdyne, along with seven7 other PRPs (the "Cooperating Respondents”Respondents") signed a project agreement in late March


2002 with the San Gabriel Basin Water Quality Authority, the Main San Gabriel Basin Watermaster, and five5 water companies (the “Water Entities”).companies. The 2002 project agreement which had a term of fifteen years, became effective May 9, 2002 and terminated in May 2017. In April 2017 and the parties executed a new project agreement which became operational on May 9, 2017. The new agreement has a ten yearten-year term and has similar provisions as the 2002 project agreement requiringrequires the Cooperating Respondents to fund through an escrow account the ongoing operation, maintenance, and administrative costs of certain treatment and water distribution facilities owned and operated by the water companies. There are also provisions in the project agreement for maintaining financial assurance.
Aerojet Rocketdyne and three ofPursuant to the 2017 agreement with the remaining Cooperating Respondents, entered into an agreement establishing final allocation among them and which also establishes as to the other Cooperating Respondent, that entity's obligation to pay an interim allocation at their current interim allocation and an arbitration process to establish their final allocation for project agreement related costs. Aerojet Rocketdyne's current share of future BPOU costs will be approximately74%.
As part of Aerojet Rocketdyne’s sale of its Electronics and Information Systems (“EIS”("EIS") business to Northrop Grumman Corporation ("Northrop") in October 2001, the EPA approved a prospective purchaser agreement with Northrop to absolve it of a pre-closing liability for contamination caused by the Azusa, California operations, which liability remains with Aerojet Rocketdyne. As part of that agreement, the Company agreed to provide a $25 million guarantee of its obligations under the project agreement.
As of September 30, 2017,March 31, 2020, the estimated range of anticipated costs was $119.1$84.8 million to $155.5$100.9 million and the accrued amount was $119.1$84.8 million included as a component of the Company’s environmental reserves. Expenditures associated with this matter are partially recoverable. See Note 8(d) below8(c) for further discussion on recoverability.
Wabash, Indiana Site
As part of the Company's automotive business that was divested in 2004, the Company owned and operated a former rubber processing plant in Wabash, Indiana from 1937 to 2004. Pursuant to a request from the Indiana Department of Environmental Management (“IDEM”), the Company conducted an initial site investigation of the soil and groundwater at the site and a report was submitted to IDEM. By letter of June 11, 2014, IDEM directed the Company to conduct additional investigation of the site, including a vapor intrusion investigation in areas in and around the site where trichloroethylene levels in groundwater were found to exceed screening levels for vapor intrusion. Vapor mitigation systems were installed in one residence and one business where indoor air screening levels were exceeded. The Company acquired a separate residence in August 2016 where indoor air screening levels were exceeded and a mitigation system was not economically feasible. The Company anticipates donating the property to the City of Wabash for use in connection with a city park.  The Company conducted further investigations of the site in accordance with the IDEM request and approved work plan. The Company met with IDEM on May 24, 2016, to present the results of the further investigation and IDEM requested the Company to submit a remedial action plan. The remedial action plan was submitted in January 2017 and approved by IDEM in March 2017. The work plan focuses on periodic monitoring and specific plans for long term remedial actions for on-site soils which will be deferred until City of Wabash access has been secured and a redevelopment plan is in place. The Company sent demands to other former owners/operators of the site to participate in the site work, but they declined to participate. As of September 30, 2017, the estimated range of the Company's share of anticipated costs for the Wabash, Indiana site was $0.4 million to $0.7 million and the accrued amount was $0.4 million. None of the expenditures related to this matter are recoverable from the U.S. government.
d.c. Environmental Reserves and Estimated Recoveries
Environmental Reserves
The Company reviews on a quarterly basis estimated future remediation costs and has an established practice of estimating environmental remediation costs over a fifteen year period, except for those environmental remediation costs with a specific contractual term. Environmental liabilities at the BPOU site are currently estimated through the term of the new project agreement.agreement, which expires in May 2027. As the period for which estimated environmental remediation costs lengthens, the reliability of such estimates decreases. These estimates consider the investigative work and analysis of engineers, outside environmental consultants, and the advice of legal staff regarding the status and anticipated results of various administrative and legal proceedings. In most cases, only a range of reasonably possible costs can be estimated. In establishing the Company’s reserves, the most probable estimate is used when determinable; otherwise, the minimum amount is used when no single amount in the range is more probable. Accordingly, such estimates can change as the Company periodically evaluates and revises these estimates as new information becomes available. The Company cannot predict whether new information gained as projects progress will affect the estimated liability accrued. The timing of payment for estimated future environmental costs is influenced by a number of factors, such as the regulatory approval process and the time required designing, constructing, and implementing the remedy.

(1) Related to the Company's legacy business operations that are primarily non-recoverable from the U.S. government.
The effect of the final resolution of environmental matters and the Company’s obligations for environmental remediation and compliance cannot be accurately predicted due to the uncertainty concerning both the amount and timing of future expenditures and due to regulatory or technological changes. The Company continues its efforts to mitigate past and future costs through pursuit of claims for recoveries from insurance coverage and other PRPs and continued investigation of new and more cost effective remediation alternatives and associated technologies.
As part of the acquisition of the Atlantic Research Corporation (“ARC”("ARC") propulsion business in 2003, Aerojet Rocketdyne entered into an agreement with ARC pursuant to which Aerojet Rocketdyne is responsible for up to $20.0 million of costs (“("Pre-Close Environmental Costs”Costs") associated with environmental issues that arose prior to Aerojet Rocketdyne’s acquisition of the ARC propulsion business. ARC is responsible for any cleanup costs relating to the ARC acquired businesses in excess of $20.0 million. Pursuant to a separate agreement with the U.S. government which was entered into prior to the completion of the ARC acquisition, these costs are recovered through the establishment of prices for Aerojet Rocketdyne’s products and services sold to the U.S. government. The Company reached the $20.0 million cap on cleanup costs in the first quarter of fiscal three months ended March 31,


2017, and expects that additional costs will be incurred due to contamination existing at the time of the acquisition and still requiring remediation and monitoring. On May 6, 2016, ARC informed Aerojet Rocketdyne that it was disputing certain costs that Aerojet Rocketdyne attributed to the $20.0 million Pre-Close Environmental Costs (“("ARC Claim”Claim"). The Company has met with ARC and responded toparties reached a settlement on March 23, 2020, resolving the ARC Claim on June 23, 2017. CertainClaim.

Estimated Recoveries
On January 12, 1999, Aerojet Rocketdyne and the U.S. government implementedreached a settlement agreement ("Global Settlement") covering environmental costs associated with the October 1997 Agreement in Principle (“Global Settlement”) resolving certain prior environmentalCompany's Sacramento site and facility disagreements, with retroactive effectits former Azusa site. Pursuant to December 1, 1998. Under the Global Settlement, the Company can recover up to 88% of its environmental remediation costs through the establishment of prices for Aerojet RocketdyneRocketdyne's products and services sold to the U.S. government resolved disagreements about an appropriate cost-sharing ratio with respect to the clean-up costs of the environmental contamination. The Global Settlement cost-sharing ratio does not have a defined term over which costs will be recovered.government. Additionally, in conjunction with the sale of the EIS business in 2001, Aerojet Rocketdyne entered into an agreement with Northrop (the “Northrop Agreement”"Northrop Agreement") whereby Aerojet Rocketdyne is reimbursed by Northrop for a portion of environmental expenditures eligible for recovery under the Global Settlement, subject to an annual billing limitation of $6.0 million and a cumulative limitation of $189.7 million. The cumulative expenditure limitation of $189.7 million which was reached in the second quarter of fiscalJune 2017. A summary ofThe following table summarizes the Northrop Agreement activity is shown below (in millions):

Excluding the receivable from Northrop of $66.0 million, theThe Company currently estimates approximately 24% 12%of its future Aerospace and Defense segment environmental remediation costs will not likely be reimbursable and are expensed.
Allowable environmental remediation costs are charged to the Company’s contracts with the U.S. government as the costs are incurred. Because these costs are recovered through forward-pricing arrangements, the ability of Aerojet Rocketdyne to continue recovering


these costs from the U.S. government depends on Aerojet Rocketdyne’s sustained business volume underfrom U.S. government contracts and programs.
While the Company is currently seekingcontinues to seek an arrangement with the U.S. government to recover environmental expenditures in excess of the reimbursement ceiling identified in the Northrop Agreement and Global Settlement, there can be no assurances that such a recovery will be obtained, or if not obtained, that such unreimbursed environmental expenditures will not have a materially adverse effect on the Company’s operating results, financial condition, and/or cash flows.

d. Arrangements with Off-Balance Sheet Risk
As of September 30, 2017,March 31, 2020, arrangements with off-balance sheet risk consisted of:
$39.1 million in outstanding commercial letters of credit,the majority of which may be renewed, primarily to collateralize obligations for environmental remediation and insurance coverage.
$29.7 million in outstanding commercial letters of credit,the majority of which may be renewed, primarily to collateralize obligations for environmental remediation and insurance coverage.
$55.453.9 million in outstanding surety bonds to primarily satisfy indemnification obligations for environmental remediation coverage.
Up to $120.0$120.0 million aggregate in guarantees by the Company of Aerojet Rocketdyne’s obligations to U.S. government agencies for environmental remediation activities.
Guarantees, jointly and severally, by the Company’s material domestic subsidiaries of their obligations under the Senior Credit Facility.
In addition to the items discussed above, the Company has and will from time to time enter into certain types of contracts that require the Company to indemnify parties against potential third-party and other claims. These contracts primarily relate to: (i) divestiture agreements, under which the Company may provide customary indemnification to purchasers of its businesses or assets including, for example, claims arising from the operation of the businesses prior to disposition, and liability to investigate and remediate environmental contamination existing prior to disposition; (ii) certain real estate leases, under which the Company may be required to indemnify property owners for claims arising from the use of the applicable premises; and (iii) certain agreements with officers and directors, under which the Company may be required to indemnify such persons for liabilities arising out of their relationship with the Company. The terms of such obligations vary. Generally, a maximum obligation is not explicitly stated.
Additionally, the Company issueshas open purchase orders and other commitments to suppliers, subcontractors, and other outsourcing partners for equipment, materials, and supplies in the normal course of business. These purchase commitmentsamounts are generally forbased on volumes consistent with anticipated requirements to fulfill purchase orders or contracts for product deliveries received, or expected to be received, from customers and would be subject to reimbursement if a cost-plus contract is terminated.

A substantial portion of these amounts are recoverable through the third quarter of fiscal 2017,Company's contracts with the Company outsourced certain information technology and cyber security functions resulting in a significant financial commitment over the next five years.U.S. government.
The Company provides product warranties in conjunction with certain product sales. The majority of the Company’s warranties are a one-year standard warranty for parts, workmanship, and compliance with specifications. On occasion, the Company has made commitments beyond the standard warranty obligation. While the Company has contracts with warranty provisions, there is not a history of any significant warranty claims experience. A reserve for warranty exposure is made on a product by product basis when it is both estimable and probable. These costs are included in the program’s estimate at completion and are expensed in accordance with the Company’s revenue recognition methodology as allowed under GAAP for that particular contract.


Note 10.9. Cost Reduction Plans
During fiscal 2015, the Company initiated the first phase ("Phase I") of the competitive improvement program (the "CIP”"CIP") comprised of activities and initiatives aimed at reducing costs in order for the Company to continue to compete successfully. Phase I is composedwas comprised of three major components: (i) facilities optimization and footprint reduction; (ii) product affordability; and (iii) reduced administrative and overhead costs. On April 6,In 2017, the Board of Directors approved the second phase (“("Phase II”II") of the Company’s previously announced CIP. Pursuant to Phase II, the Company plans to expandexpanded its CIP and further consolidateconsolidated its Sacramento, California, and Gainesville, Virginia sites, while centralizingit centralized and expandingexpanded its existing presence in Huntsville, Alabama. The Company currently estimates that it will incurthe restructuring and related costs of the Phase I and II programs of approximately $235.1will be $197.0 million (including approximately $60.5 million of capital expenditures). The Company and has incurred $71.6$178.1 million of such costs through September 30, 2017,March 31, 2020, including $29.8$54.7 million in capital expenditures.

In addition to the employee-related Phase I and II obligations, the Company incurred non-cash accelerated depreciation expense of $3.5 million and $0.6 million in the first nine months of fiscal 2017 and 2016, respectively, associated with changes in the estimated useful lives of long-lived assets.


Note 11.10. Retirement Benefits
Pension Benefits
The Company's defined benefit pension plan future benefit accrual was discontinued in fiscal 2009. As offollowing table presents the last measurement date of December 31, 2016, the assets, projected benefit obligations, and unfunded pension obligation for the tax-qualified pension plans were approximately $925.1 million, $1,492.1 million, and $548.2 million, respectively.
The Company expects to make cash contributions of $75.8 million to its tax-qualified defined benefit pension plan in fiscal 2017 of which $34.0 million is expected to be recoverable from its U.S. government contracts in fiscal 2017 with the remaining $41.8 million expected to be recoverable from its U.S. government contracts in the future. The Company has funded $67.0 million to its tax-qualified defined benefit pension plan in the first nine months of fiscal 2017 and in the fourth quarter of fiscal 2017 expects to fund $8.8 million. The Company generally is able to recover cash contributions related to its tax-qualified defined benefit pension plan as allowable costs on U.S. government contracts, but there can be differences between when the Company contributes cash to its tax-qualified defined benefit pension plan under pension funding rules and recovers the costs under the U.S. government Cost Accounting Standards.
On October 17, 2017, the Company's tax-qualified defined benefit pension plan purchased non-participating annuity contracts in the amount of $34.7 million for approximately 2,800 participants which will reduce future service costs of the pension plan.
The funded status of the Company's tax-qualified pension plan may be adversely affected by the investment experience of the plan's assets, by any changes in U.S. law and by changes in the statutory interest rates used by tax-qualified pension plans in the U.S. to calculate funding requirements. Accordingly, if the performance of the plan's assets does not meet assumptions, if there are changes to the Internal Revenue Service regulations or other applicable law, or if other actuarial assumptions are modified, future contributions to the underfunded pension plans could be higher than the Company expects.
Medical and Life Insurance Benefits
The Company provides medical and life insurance benefits to certain eligible retired employees, with varied coverage by employee group. Generally, employees hired after January 1, 1997, are not eligible for retiree medical and life insurance benefits. The medical benefit plan provides for cost sharing between the Company and its retirees in the form of retiree contributions, deductibles, and coinsurance. Medical and life insurance benefit obligations are unfunded. Medical and life insurance benefit cash payments for eligible retired employees are recoverable from the Company’s U.S. government contracts.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Unless otherwise indicated or required by the context, as used in this Quarterly Report on Form 10-Q, the terms “the"the Company,” “we,” “our”" "we," "our" and “us”"us" refer to Aerojet Rocketdyne Holdings, Inc. and all of its subsidiaries that are consolidated in conformity with accounting principles generally accepted in the United States of America (“GAAP”("GAAP").
The preparation of the consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In addition, since our operating cycle is primarily based on long-term contracts with various delivery schedules, our operating results for interim periods may not be indicative of the results of operations for a full year or future periods. This section contains a number of forward-looking statements, all of which are based on current expectations and are subject to risks and uncertainties including those described in this Quarterly Report under the heading “Forward-Looking"Forward-Looking Statements." Actual results may differ materially. This section should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 20162019, and periodic reports subsequently filed with the Securities and Exchange Commission (“SEC”("SEC").
Overview
We are a manufacturer of aerospace and defense products and systems with a real estate segment. Our operations are organized into two segments:

A reconciliation of the Non-GAAP measures to the most directly comparable GAAP measures is presented later in the Management’s Discussion and Analysis under the heading “Operating Segment Information” and “Use"Use of Non-GAAP Financial Measures."
We are operating in an environment thatOur business outlook is characterizedaffected by both increasing complexity in the global security environment and continuing worldwide economic pressures.pressures, including those resulting from the coronavirus ("COVID-19") pandemic. A significant component of our strategy in this environment is to focus on protecting our employees' health and safety, delivering excellent performance to our customers, driving improvements and efficiencies across our operations, and creating value through the enhancement and expansion of our business.
We continuously evaluate a broad range of options that could be implemented to increase operational efficiency across all sites, and improve our overall market competitiveness.  Our decisions will be focused on moving us forward to solidify our leadership in the propulsion markets.
Some of the significant challenges we face are as follows:uncertainty associated with the COVID-19 pandemic, dependence upon U.S. government programs and contracts, future reductions or changes in U.S. government spending in our markets, implementation of the competitive improvement program (the "CIP"), environmental matters, capital structure, and our underfunded retirement benefit plans.plans, and cyber security.




COVID-19
During the three months ended March 31, 2020, there was minimal impact to our financial results and operations as a result of the COVID-19 outbreak that began in late 2019, and was declared a pandemic by the World Health Organization on March 11, 2020. The safety and welfare of our employees is our top priority, and during the quarter, a number of safety protocols were established. Selected and site-specific work and travel restrictions, in addition to other measures intended to reduce the spread of COVID-19, were introduced. Although we did not experience significant absenteeism or supply chain disruption, the extent to which the COVID-19 pandemic impacts our financial results and operations for 2020 and beyond will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the pandemic and the actions being taken to contain and treat it, and other indirect effects that may come as a result of actions taken by governments, companies, and individuals in response to the pandemic and its economic impact.
As a defense industrial-base U.S. government contractor, we are considered an essential business by the U.S. and state governments and we continue to operate as such during the COVID-19 pandemic. We are taking a variety of measures to maintain the availability and functionality of our critical infrastructure, to promote the safety and security of our employees and to support the communities in which we operate. In making decisions regarding our operations, we take into account public and private sector policies and initiatives to reduce the transmission of COVID-19, such as the imposition of travel restrictions, the promotion of social distancing and the adoption of work-from-home requirements for employees where practicable, and all of these policies and initiatives could impact our operations. Due to the evolving nature of the COVID-19 pandemic, we are not able at this time to estimate its full impact on our financial results and operations.
Major Customers
The principal end user customers of our products and technology are primarily agencies of the U.S. government. Since a majority of our sales are, directly or indirectly, to the U.S. government, funding for the purchase of our products and services generally follows trends in U.S. aerospace and defense spending. However, individual U.S. government agencies, which include the military services, NASA, the Missile Defense Agency, and the prime contractors that serve these agencies, exercise independent purchasing power within “budget top-line”"budget top-line" limits. Therefore, sales to the U.S. government are not regarded as sales to one customer, but rather each contracting agency is viewed as a separate customer.
SalesThe following table summarizes net sales to the U.S. government and its agencies, including net sales to our significant customers disclosed below, were as follows:

Industry Update
Our primary aerospace and defense customers include the DoD and its agencies, NASA, and the prime contractors that supply products to these customers. We rely on U.S. government spending on aerospace and defense products and systems, and our backlog depends, in large part, on continued funding by the U.S. government for the programs in which we are involved. These funding levels are not generally correlated with any specific economic cycle, but rather followWhile U.S. and state governments continue to address the cycle of general public policyCOVID-19 pandemic, our customers continue to operate under the Public Law 116-93,


which includes DoD and political supportNASA full-year appropriations bills for this type of funding. Moreover, although our contracts often contemplate that our services will be performed over a period of several years,Government Fiscal Year 2020. Additionally, the U.S. Congress must appropriate fundsgovernment enacted the Coronavirus Aid, Relief & Economic Security ("CARES") Act on March 27, 2020, which provides $60 million of supplemental appropriations for NASA operational adjustments due to delays and center closures and an additional $2.45 billion for the DoD to support the defense industrial-base. There is no assurance that we will receive any benefit from the CARES Act or other emergency support legislation. Disruptions to our customer’s facilities or delays in supply chain as a given program and theresult of COVID-19 could delay or decrease expenditures by U.S. President must sign into law such appropriations legislation each government fiscal year (“GFY”) and may significantly increase, decrease or eliminate, funding foragencies. Such a program. A decrease in DoD and/or NASA expenditures, the elimination or curtailment of a material program in which we are or hope to be involved, or changes in payment patterns of our customers as a result of changes in U.S. government outlays, could have a material adverse effect on our operating results, financial condition, and/or cash flows.
Congress was not able to pass full year appropriations for either DoD or NASA prior to the start of GFY 2017 on October 1, 2016, necessitating a short-term Continuing Resolution (“CR”) into December 2016.  After the 2016 U.S. Presidential Election in November 2016, Congress passed another CR into mid-2017 to allow the new Administration an opportunity to shape federal spending.  On May 5, 2017, President Trump signed into law the Consolidated Appropriations Act of 2017, an omnibus appropriations bill for GFY 2017, including appropriations for DoD and NASA; however, the delayed completion of the GFY2017 spending bills resulted in a delay to the release of the President’s Budget Request for GFY2018.  With a truncated legislative cycle, Congress was unable to pass GFY 2018 bills before October 1, 2017, necessitating another CR through December 8, 2017. 
The Space Launch Systems ("SLS") appears to remain a top Congressional priority as the CR included a provision to allow NASA the funding flexibility for SLS and deep exploration to remain on track. The SLS program also has enjoyed wide,


bipartisan support in both chambers of Congress. We maintain a strong relationship with NASA and our propulsion systems have been powering NASA launch vehicles and spacecraft since the inception of the U.S. space program. Our booster, upper stage and Orion vehicle propulsion systems are currently baselined on the new SLS vehicle and both upper stage and booster engines are in development for future SLS variants. Due to the retirement of the space shuttle fleet, U.S. astronauts have been dependent on Russian Soyuz flights for access to and from the International Space Station ("ISS") for the better part of this decade. NASA has been working to re-establish U.S. manned space capability as soon as possible through development of a new “space taxi” to ferry astronauts and cargo to the ISS. In 2014, Boeing’s CST-100 Starliner capsule, powered by Aerojet Rocketdyne propulsion, was selected by NASA to transport astronauts to and from the ISS. As Boeing’s business partner, Aerojet Rocketdyne will be providing the propulsion system for this new capsule, thereby supplementing its work for NASA on the SLS designed for manned deep space exploration. In both instances, we have significant propulsion content and we look forward to supporting these generational programs for NASA.
The competitive dynamics of our multi-faceted marketplace vary by product line and customer as we experience many of the same influences felt by the broader aerospace and defense industry.  The large majority of products we manufacture are highly complex, technically sophisticated and extremely hazardous to build, demanding rigorous manufacturing procedures and highly specialized manufacturing equipment.  While historically these factors, coupled with the high cost to establish the infrastructure required to meet these needs, posed substantial barriers to entry, modern design tools and manufacturing techniques (e.g., additive manufacturing) available to new entrants with the ability to self-fund start-up as well as development costs has led to increased competition in space related markets. To date, the competition has been limited to a few participants who tend to be narrowly focused on products that are sub-elements of our overall product portfolio. For example, entrepreneurs such as SpaceX and Blue Origin, who have been or are in the process of developing liquid fuel propulsion capabilities are primarily focused on the development of space propulsion systems for heavy lift launch vehicles and are not pursuing or participating in the missile defense or tactical propulsion business segments that make up a substantial portion of our overall business. These new entrepreneurs have signaled their intent to compete primarily on price and are therefore bringing pressure to bear on existing cost paradigms and manufacturing methodologies.
Competitive Improvement Program
During fiscal 2015, we initiated the first phase ("Phase I") of the CIP comprised of activities and initiatives aimed at reducing costs in order for us to continue to compete successfully. Phase I is composed of three major components: (i) facilities optimization and footprint reduction; (ii) product affordability; and (iii) reduced administrative and overhead costs. On April 6, 2017, the Board of Directors approved the second phase (“Phase II”) of our previously announced CIP. Pursuant to Phase II, our plans are to expand CIP and further consolidate our Sacramento, California, and Gainesville, Virginia sites, while centralizing and expanding our existing presence in Huntsville, Alabama.
When fully implemented, we anticipate that the CIP will result in annual cost reductions as follows (in millions):
Annual cost reductions related to Phase I (expected during 2019)$145.0
Annual cost reductions related to Phase II (expected during 2021)    85.0
Total annual cost reductions$230.0
We currently estimate that we will incur restructuring and related costs of the Phase I and II programs of approximately $235.1 million (including approximately $60.5 million of capital expenditures). We have incurred $71.6 million through September 30, 2017, including $29.8 million in capital expenditures.
Environmental Matters
Our current and former business operations are subject to, and affected by, federal, state, local, and foreignlocal environmental laws and regulations relating to the discharge, treatment, storage, disposal, investigation, and remediation of certain materials, substances, and wastes. Our policy is to conduct our business with due regard for the preservation and protection of the environment. We continually assess compliance with these regulations and we believe our current operations are materially in compliance with all applicable environmental laws and regulations.

WeDuring 2020, we expect to make cash contributions of $75.8approximately $46.0 million to our tax-qualified defined benefit pension plan in fiscal 20172020, including $13.9 million of which $34.0cash and $32.1 million is expected to be recoverable from our U.S. government contracts in fiscal 2017 with the remaining $41.8 million expected to be recoverable from our U.S. government contracts in the future. We have funded $67.0 million to our tax-qualified defined benefit pension plan in the first nine months of fiscal 2017 and in the fourth quarter of fiscal 2017 we expect to fund $8.8 million.prepayment credits. We generally are able to recover cash contributions related to our tax-qualified defined benefit pension plan as allowable costs on our U.S. government contracts, but there can beare differences between when we contribute cash to our tax-qualified defined benefit pension plan under pension funding rules and recoverwhen it is recoverable under the Cost Accounting Standards.Standards ("CAS").
The COVID-19 pandemic and resulting global disruptions have caused significant economic uncertainty and volatility in financial markets which could adversely impact the funded status of our tax-qualified defined benefit pension plan. The funded status of our retirement benefit plans may be adversely affectedpension plan is impacted by the investment experience of the plan assets, by any changes in U.S. law, and by changes in the statutory interest rates used by the tax-qualified pension plansplan in the U.S. to calculate funding requirements. Accordingly, if the performance of our retirement benefitplan assets does not meet our assumptions, if there are changes to the Internal Revenue Service regulations or other applicable law or if other actuarial assumptions are modified, our future contributions to our underfunded retirement benefit planspension plan could be higher than we expect.

We incurred a pre-tax charge of $34.1 million in the third quarter of fiscal 2016 associated with the extinguishment of the 7 1/8% Notes. The $34.1 million pre-tax charge was comprised of $24.6 million paid in excess of the par value and $9.5 million associated with the write-off of unamortized deferred financing costs.
We retired $13.0 million principal amount of our delayed draw term loan resulting in a loss of $0.3 million.
We recorded a charge of $0.1 million associated with the amendment to our $750.0 million senior secured senior credit facility (the "Senior Credit Facility").

A valuation allowance is required when it is more-likely-than-not that all or a portion of deferred tax assets may not be realized. Assessing the need for a valuation allowance requires management to evaluate, on a quarterly basis, all available evidence, both positive and negative. As of September 30, 2017, we continue to believe that the weight of the positive evidence outweighed the negative evidence regarding the realization of our net deferred tax assets.

Market conditions and interest rates significantly affect the assets and liabilities of our retirement benefit plans. Pension accounting permits market gains and losses to be deferred and recognized over a period of years. This “smoothing” results in the creation of other accumulated income or losses which will be amortized to retirement benefit expense or benefit in future years. The accounting method we utilize recognizes one-fifth of the unamortized gains and losses associated with the market-related value of pension assets and all other gains and losses, including changes in the discount rate used to calculate benefit costs each year. Investment gains or losses for this purpose are the difference between the expected return and the actual return on the market-related value of assets which smoothes market related asset values over three years. Although the smoothing period mitigates some volatility in the calculation of annual retirement benefit expense, future expenses are impacted by changes in the market value of assets and changes in interest rates.R&D credits.
Operating Segment Information:
We evaluate our operating segments based on several factors, of which the primary financial measure is segment performance. Segment performance represents net sales less applicable costs, expenses and provisions for unusual items relating to the segment. Excluded from segment performance are: corporate income and expenses, interest expense, interest income, income taxes, legacy income or expenses, and unusual items not related to the segment. We believe that segment performance provides information useful to investors in understanding our underlying operational performance. In addition, we provide the Non-GAAP financial measure of our operational performance called segment performance before environmental remediation provision adjustments, retirement benefits, and unusual items. We believe the exclusion of the items listed above


permits an evaluation and a comparison of results for ongoing business operations, and it is on this basis that management internally assesses operational performance.

In addition to segment performance (discussed above), weAdjusted EBITDAP, Adjusted Net Income, and Adjusted EPS
We provide the Non-GAAP financial measuremeasures of our operational performance called Adjusted EBITDAP.EBITDAP, Adjusted Net Income, and Adjusted EPS. We use this metricthese metrics to measure our operating and total Company performance. We believe that for management

Critical Accounting Policies and Estimates
Our financial statements are prepared in accordance with GAAP that offer acceptable alternative methods for accounting for certain items affecting our financial results, such as determining inventory cost,contract costs, depreciating long-lived assets, and recognizing revenues.
The preparation of financial statements requires the use of estimates, assumptions, judgments, and interpretations that can affect the reported amounts of assets, liabilities, revenues, and expenses, the disclosure of contingent assets and liabilities and other supplemental disclosures. The development of accounting estimates is the responsibility of our management. Management discusses those areas that require significant judgment with the audit committee of our board of directors. All of our financial disclosures in our filings with the SEC have been reviewed with the audit committee. Although we believe that the positions we have taken with regard to uncertainties are reasonable, others might reach different conclusions and our positions can change over time as more information becomes available. If an accounting estimate changes, its effects are accounted for prospectively and, if significant, disclosed in notes of the consolidated financial statements.Notes to Unaudited Condensed Consolidated Financial Statements.
The areas most affected by our accounting policies and estimates are revenue recognition, other contract considerations, goodwill, retirement benefit plans, litigation, environmental remediation costs and recoveries, and income taxes. Except for income taxes and litigation matters related to legacy operations, which are not allocated to our operating segments, these areas affect the financial results of our business segments.
In our Aerospace and Defense segment, recognition of profit on long-term contracts requires the use of assumptions and estimates related to total contract revenue, the total cost at completion and the measurement of progress towards completion. Due to the nature of the programs, developing the estimated total contract revenue and cost at completion requires the use of significant judgment. Estimates are continually evaluated as work progresses and are revised as necessary. Factors that must be considered in estimating the work to be completed include, but not limited to: labor productivity, the nature and technical complexity of the work to be performed, availability and cost volatility of materials, subcontractor and vendor performance, warranty costs, volume assumptions, anticipated labor agreements, inflationary trends, schedule delays, availability of funding from the customer, and the recoverability of costs incurred outside the original contract included in any estimates to complete. We review contract performance and cost estimates for some contracts at least monthly and for others at least quarterly and more frequently when circumstances significantly change. When a change in estimate is determined to have an impact on contract profit, we will record a positive or negative adjustment to the statement of operations. Changes in estimates and assumptions related to the status of certain long-term contracts may have a material effect on our operating results. The following table summarizes the impact of the change in significant contract accounting estimates on our Aerospace and Defense segment operating results accounted for under the percentage-of-completion method of accounting:

Arrangements with Off-Balance Sheet Risk
As of September 30, 2017, arrangements with off-balance sheet risk consisted of:
$39.1 million in outstanding commercial letters of credit, the majority of which may be renewed, primarily to collateralize obligations for environmental remediation and insurance coverage.
$55.4 million in outstanding surety bonds to primarily satisfy indemnification obligations for environmental remediation coverage.
Up to $120.0 million aggregate in guarantees by us of Aerojet Rocketdyne’s obligations to U.S. government agencies for environmental remediation activities.
Guarantees, jointly and severally, by our material domestic subsidiaries of their obligations under our Senior Credit Facility.
In addition to the items discussed above, we have and will from time to time enter into certain types of contracts that require us to indemnify parties against potential third-party and other claims. These contracts primarily relate to: (i) divestiture agreements, under which we may provide customary indemnification to purchasers of our businesses or assets including, for example, claims arising from the operation of the businesses prior to disposition, liability to investigate and remediate environmental contamination existing prior to disposition; (ii) certain real estate leases, under which we may be required to indemnify property owners for claims arising from the use of the applicable premises; and (iii) certain agreements with officers and directors, under which we may be required to indemnify such persons for liabilities arising out of their relationship with us. The terms of such obligations vary. Generally, a maximum obligation is not explicitly stated.
Additionally, we issue purchase orders and make other commitments to suppliers for equipment, materials, and supplies in the normal course of business. These purchase commitments are generally for volumes consistent with anticipated requirements to fulfill purchase orders or contracts for product deliveries received, or expected to be received, from customers and would be subject to reimbursement if the contract is terminated. During the third quarter of fiscal 2017, we outsourced certain information technology and cyber security functions resulting in a significant financial commitment over the next five years.
We provide product warranties in conjunction with certain product sales. The majority of our warranties are one-year standard warranties for parts, workmanship, and compliance with specifications. On occasion, we have made commitments beyond the standard warranty obligation. While we have contracts with warranty provisions, there is not a history of any significant warranty claims experience. A reserve for warranty exposure is made on a product by product basis when it is both estimable and probable. These costs are included in the program’s estimate at completion and are expensed in accordance with our revenue recognition methodology as allowed under GAAP for that particular contract.2019.

The $25.9 million of cash provided byused in operating activities infor the first ninethree months of fiscal 2017ended March 31, 2020, was primarilycomparable with the result of $200.7 million of cash generated by income from operations before income taxes adjusted for non-cash items which was offset by cash used to fund working capital (defined as accounts receivables, inventories, other current assets, accounts payables, contract advances, real estate activities, and other current liabilities). The funding of working capital was comprised of the following: (i) an increase of $135.2 million in accounts receivables due to the timing of net sales and milestone billings on a space program contract and (ii) a decrease of $39.1 million in cash advances on long-term contracts, partially offset by a decrease of $24.3 million in inventories primarily due to a decrease in overhead costs. Further, we funded $67.0 million to our tax-qualified defined benefit pension plan in the first nine months of fiscal 2017 which was partially offset by $21.3 million of income tax refunds received in the first nine months of fiscal 2017.
The $49.2 million of cash provided by operating activities in the first nine months of fiscal 2016 was primarily the result of $136.7 million of cash generated by the net loss before income taxes adjusted for non-cash items which was offset by cash used to fund working capital (defined as accounts receivables, inventories, other current assets, accounts payable, contract advances, real estate activities, and other current liabilities). The funding of working capital is primarily due to the following: (i) a decrease of $26.9 million in cash advances on long-term contracts; (ii) an increase of $13.3 million in other current assets, net primarily related to income taxes; and (iii) a decrease of $57.8 million in other current liabilities primarily due to the timing of payments associated with employee compensation, income taxes, and interest expense. The funding of working capital was partially offset by a decrease of $22.2 million in accounts receivable primarily due to the timing of net sales. In addition, we funded $29.9 million to our tax-qualified defined benefit pension plan during the first nine months of fiscal 2016.prior year period.
Net Cash Used Inin Investing Activities
During the first ninethree months of fiscal 2017, we purchased Coleman Aerospace for $17.0 million.
During the first nine months of fiscal 2017ended March 31, 2020 and 2016,2019, we had capital expenditures of $10.5$3.0 million and $30.5$1.5 million, respectively. The decrease in capital expenditures is primarily due to timing of expenditures related to our fiscal 2017 capital plan.
Net Cash Used in Financing Activities
During the first ninethree months of fiscal 2017,ended March 31, 2020 and 2019, we had debt repayments of $15.0$4.9 million (see below). and $5.5 million, respectively. See a summary of our debt activity below.

Outlook
Short-term liquidity requirements consist primarily of recurring operating expenses, including but not limited to costs related to our capital and environmental expenditures, company-funded R&D expenditures, debt service requirements, and retirement benefit plans. We believe that our existing cash and cash equivalents and availability under the Senior Credit Facility coupled with cash generated from our revolving credit facilityfuture operations will provide sufficient funds to meet our operating plan which includes our CIP Phase I and Phase II, and AR1 engine development costs, for the next twelve months. The operating plan for this period provides for full operation of our businesses, andincluding interest and principal payments on our debt.debt payments. As of September 30, 2017,March 31, 2020, we had $392.5$902.6 million of cash and cash equivalents as well as $310.9$620.3 million of available borrowings under our Senior Credit Facility. Based on our existing debt agreements, we were in compliance with our financial and non-financial covenants as of September 30, 2017.March 31, 2020. Our failure to comply with these covenants could result in an event of default that, if not cured or waived by the lenders, could result in the acceleration of the Senior Credit Facility and 2¼% Notes. In addition, our failure to pay principal and interest when due is a default under the Senior Credit Facility, and in certain cases, would cause a cross default on the 2¼% Notes.
We are committed to a cash management strategy that maintains liquidity to adequately support the operation of the business, our growth strategy, andas well as to withstand unanticipated business volatility. We believe that cash generatedvolatility, including any impact arising from operations, together with our current levels of cash and investments as well as availability under our revolving credit facility, should be sufficient to maintain our ongoing operations, support working capital requirements, fund the CIP, cash contributions to our tax-qualified defined benefit pension plan, and fund anticipated capital expenditures related to projected business growth.COVID-19 pandemic. Our cash management strategy includes maintaining the flexibility to pay down debt and/or repurchase shares depending on economic and other conditions. In connection with the implementation of our cash management strategy, our management may seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise if we believe that it is in our best interests. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
We expect to make cash contributions of $75.8 million to our tax-qualified defined benefit pension plan in fiscal 2017 of which $34.0 million is expected to be recoverable from our U.S. government contracts in fiscal 2017 with the remaining $41.8 million expected to be recoverable from our U.S. government contracts in the future. We have funded $67.0 million to our tax-qualified defined benefit pension plan in the first nine months of fiscal 2017 and in the fourth quarter of fiscal 2017 we expect to fund $8.8 million. We generally are able to recover cash contributions related to our tax-qualified defined benefit pension plan as allowable costs on our U.S. government contracts, but there can be differences between when we contribute cash to our tax-qualified defined benefit pension plan under pension funding rules and recover it under the Cost Accounting Standards.
Potential future business acquisitions depend, in part, on the availability of financial resources at an acceptable cost of capital. We expect to utilize cash on hand and cash generated by operations, as well as cash available under our Senior Credit Facility, which may involve renegotiation of credit limits to finance any future acquisitions. Other sources of capital could include the issuance of common and/or preferred stock, and the placement of debt.debt, or combination of both. We periodically evaluate capital markets and may access such markets when circumstances appear favorable. We believe that sufficient capital resources will be available from one or several of these sources to finance any future acquisitions. However, no assurances can be made that acceptable financing will be available, or that acceptable acquisition candidates will be identified, or that any such acquisitions will be accretive to earnings.
On March 13, 2020, we announced that our Board of Directors authorized and approved a new share repurchase program allowing us to repurchase our outstanding common stock with an aggregate market value of up to $100 million over a period of up to 18 months; however, management has discretion as to whether any repurchases will be executed. The timing of any share repurchases will be based on available liquidity, cash flows and general market conditions. The repurchase program may be executed through various methods, including open market purchases or privately negotiated transactions.
As disclosed in Notes 8(a) and 8(b) and 8(c) ofin the Notes to Unaudited Condensed Consolidated Financial Statements,unaudited condensed consolidated financial statements, we have exposure for certain legal and environmental matters. We believe that it is currently not possible to estimate the impact, if any, that the ultimate resolution of certain of these matters will have on our financial position, results of operations, or cash flows.
In September 2017, we entered into an agreement to lease 122,000-square feet of office space in Huntsville, Alabama. The term of the lease is twenty years and is expected to commence in March 2018 resulting in an estimated financial commitment of $48.8 million representing a present value of $25.1 million. The lease obligation over the next five fiscal years is as follows: zero in fiscal 2017, $1.2 million in fiscal 2018, and approximately $2.0 million each year for fiscal 2019 through fiscal 2021.
In October 2017, we entered into an agreement to lease a new 136,000-square-foot advanced manufacturing facility located in Huntsville, Alabama. The term of the lease is thirty-one years and is expected to commence in December 2018


resulting in an estimated financial commitment of $32.8 million representing a present value of $21.0 million. The lease obligation over the next five fiscal years is as follows: zero in fiscal 2017, $0.9 million in fiscal 2018, and $1.6 million each year for fiscal 2019 through fiscal 2021.
Major factors that could adversely impact our forecasted operating cash and our financial condition are described in the section “Risk Factors”"Risk Factors" in Item 1A of our Annual Report to the SEC on Form 10-K for the fiscal year ended December 31, 2016.2019.

In December 2016, we notified holders of our 4 1/16% Debentures that we would redeem, on February 3, 2017, all of their 4 1/16% Debentures at a purchase price equal to 100% of the principal amount of the 4 1/16% Debentures to be redeemed, plus any accrued and unpaid interest. In January 2017, $35.6 million of the 4 1/16% Debentures (the entire amount outstanding as of December 31, 2016) were converted to 3.9 million shares of common stock.
The fair valuesvalue of the 2 1/4% Notes and 4 1/16% Debentures werewas determined using broker quotes that are based on open markets for the Company’sour debt securities (Level 2 securities). The fair value of the term loan bore interest at variable rates, which adjustedMarch 31, 2020, was estimated based on market conditions,a third-party model used to derive a relative value price using comparable corporate loans within the same industry, credit quality, and itscurrency. At December 31, 2019, the term loan carrying value approximated fair value.
Cash and Marketable Securities
We also have exposure to changes in interest rates related to interest earned and market value on our cash and cash equivalents and marketable securities. Our cash and cash equivalents and marketable securities consist of cash, time deposits, money market funds, and investment grade corporate debt securities. Our investment policy and strategy are focused on preservation of capital and supporting our liquidity requirements. Changes in U.S. interest rates affect the interest earned on our cash and cash equivalents and marketable securities, and the market value of those securities.
Pension Assets and Liabilities
Our tax-qualified pension assets and liabilities are subject to interest rate risk. Information concerning our interest rate risk related to our tax-qualified pension assets and liabilities can be found in Part 7, Item 1, Management’s Discussion and Analysis of Financial Condition and Results of Operations under the caption "Critical Accounting Policies" in our Annual Report on Form 10-K for the year ended December 31, 2019.
Item 4. Controls and Procedures
Evaluation of disclosure controls and procedures
Management has conducted anBased on our management’s evaluation (with the participation of our Chief Executive Officerprincipal executive officer and Chief Financial Officer)principal financial officer), as of the effectivenessend of the designperiod covered by this report, our principal executive officer and operation of the Company’sprincipal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of September 30, 2017. As a result of the material weakness in the Company’s internal control over financial reporting discussed below, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were notare effective as of September 30, 2017.


Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in company reports filedthat we file or submittedsubmit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’sSEC rules and forms. Disclosure controlsforms and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in company reports filed under the Exchange Act is accumulated and communicated to our management, including the Company’s Chief Executive Officerour principal executive officer and Chief Financial Officerprincipal financial officer, as appropriate to allow timely decisions regarding required disclosure as of the end of the period covered by this report.
We previously identified and disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, a material weakness in our internal control over financial reporting as we did not maintain adequate controls over the completeness and accuracy of our accounting for income taxes, including the income tax provision and related tax assets and liabilities.
Income tax accounting remediation efforts
Management has strengthened the income tax function by hiring additional key internal tax personnel with the requisite background and knowledge. During the the third quarter of fiscal 2017, through these resources, management has designed and implemented quarterly controls to validate the completeness and accuracy of financial information utilized in the preparation of our income tax provision, including the related income tax assets and liabilities. Notwithstanding the above, the identified material weakness in our internal control over financial reporting will not be considered remediated until the new controls are in operation for a sufficient period of time (including certain annual controls which are still being designed), and are concluded by management to be designed and operating effectively.disclosure.
Changes in internal control over financial reporting
Other than the controls over income tax accounting implemented during the third quarter of fiscal 2017, as discussed above, thereThere were no changes in internal control over financial reporting that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the effectiveness of our internal control over financial reporting.

Item 1A. Risk Factors
There have been noThe information presented below sets forth what we reasonably believe represent material changes from ourto the risk factors as previously reporteddescribed in our Annual Report to the SEC on Form 10-K for the fiscal year ended December 31, 2016.2019, and should be read in conjunction with the risk factors therein and the information described in this Quarterly Report.
Our results of operations and financial position may be negatively impacted by the COVID-19 pandemic, and the resulting economic disruption.
In December 2019, COVID-19 surfaced in Wuhan, China and the World Health Organization declared COVID-19 a pandemic on March 11, 2020. Similarly, all the states and local governments in communities where we operate have issued various state of emergency decrees or "Stay at Home" orders restricting non-essential business activities. As a defense


industrial-base U.S. government contractor, we are considered an essential business by the U.S. and state governments and we continue to operate as such during the COVID-19 pandemic. However, the future impact of the COVID-19 pandemic is highly uncertain and we cannot predict if further governmental restrictions will be issued or if developments will cause a material change in our ability to maintain and operate our business. Additionally, the lifting and easing of U.S., state, and local government restrictions could also increase the risk of future outbreaks or exposure of our workforce to COVID-19 which may impact employee health and absenteeism.
We are also actively monitoring the COVID-19 pandemic and its potential impact on our employees, customers, and supply chain. While some of our employees are able to work remotely, a significant number can only perform their job functions on site, and we have promulgated policies designed to insure appropriate social distancing, employee protection, enhanced cleaning protocols, and health monitoring. Even so, there remains the risk of disruption or reduced efficiency caused by social distancing and other protective measures as well as elevated employee absence because of illness or required quarantines.
While our customers and suppliers generally continue to operate and perform their missions, some facilities have temporarily reduced or halted operations due to precautionary measures, staffing illness, or cleaning disruptions. For example, on March 20, 2020, NASA's Stennis Space Center, an engine test site for our space programs, entered into Stage 4 of their coronavirus response framework which limits access to the facility forpersonnel supporting activities necessary to protect life and critical infrastructure. The length and severity of such delays and closures, and any impact they will have on our operations, is uncertain. We cannot predict whether the current or future closures of customers and suppliers facilities related to the COVID-19 pandemic will have a material adverse effect on our financial results and operations.
In addition, the COVID-19 pandemic and resulting global disruptions have caused significant economic uncertainty and volatility in financial markets. Moreover, additional or unforeseen effects from the COVID-19 pandemic and actions taken by governments, companies, and individuals in response to the pandemic may affect our results of operations and financial positions in unexpected ways.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
None.Issuer Purchases of Equity Securities

On March 13, 2020, we announced that our Board of Directors authorized and approved a new share repurchase program ("Repurchase Program") allowing us to repurchase our outstanding common stock with an aggregate market value of up to $100 million, from time to time, over a period of up to 18 months. The repurchase program may be executed through various methods, including open market purchases or privately negotiated transactions.The table below provides information about the Repurchase Program activity.

Adoption of Executive Change in Control Severance Policy
On November 1, 2017, the Board, upon recommendation of the Committee, adopted an executive change in control severance policy (the “CIC Policy”).
The CIC Policy provides certain executive officers of the Company and its subsidiaries who have been designated in writing by the Board, other than Warren Lichtenstein and Eileen Drake, with compensation and benefits upon a termination of their employment by the Company without “cause” or by executive for “good reason” (including due to executive’s death or disability) within the 6-month period preceding a “change in control” through the 18-month period following a “change in control” (each, as defined in the CIC Policy).
In the event of an applicable termination of employment, the executive shall be entitled to the following:


lump sum payment equal to executive’s annual base salary;
prorated portion of incentive compensation under the Company’s Short-Term Incentive Plan (“STIP”) to the “termination date” (as defined in the CIC Policy), and full STIP payment for the prior fiscal year;
lump sum payment equal to the target incentive compensation executive could have received under the STIP for the fiscal year in which the termination date occurs;
payment of COBRA benefit premiums until the earlier of the 12-month anniversary of the termination date or when eligible for health insurance coverage through another employer;
to the extent unvested, immediate full vesting of all of the executive’s equity awards (at target performance, if applicable); and
outplacement services for a period of 12 months starting no later than 90 days from date of termination with a maximum value of $15,000.
Receipt of compensation and benefits under the CIC Policy is contingent on the executive’s timely execution of a release in a form prescribed by the Company.
The foregoing description of the CIC Policy does not purport to be complete and is qualified in its entirety by reference to the full text of the CIC Policy, which is attached as Exhibit 10.1 to this Quarterly Report on Form 10-Q and incorporated herein by reference.None.
