Notes to Unaudited Condensed Consolidated Financial Statements

Note 1. Basis of Presentation and Nature of Operations

Aerojet Rocketdyne Holdings, Inc. (“Aerojet Rocketdyne Holdings” or the “Company”) has prepared the accompanying unaudited condensed consolidated financial statements, including its accounts and the accounts of its wholly-owned subsidiaries, in accordance with the instructions to Form 10-Q. The year-end, December 31, 2016, condensed consolidated balance sheet was derived from audited financial statements, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). These interim financial statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Certain reclassifications have been made to financial information for the prior year to conform to the current year’s presentation.

The Company believes the accompanying unaudited condensed consolidated financial statements reflect all adjustments, including normal recurring accruals, necessary for a fair statement of its financial position, results of operations, and cash flows for the periods presented. All significant intercompany balances and transactions have been eliminated in consolidation. The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In addition, the operating results for interim periods may not be indicative of the results of operations for a full year.

The Company is a manufacturer of aerospace and defense products and systems with a real estate segment. The Company’s operations are organized into two segments:

Aerospace and Defense — includes the operations of the Company’s wholly-owned subsidiary Aerojet Rocketdyne, Inc. (“Aerojet Rocketdyne”), a leading technology-based designer, developer and manufacturer of aerospace and defense products and systems for the United States (“U.S.”) government, including the Department of Defense (“DoD”), the National Aeronautics and Space Administration (“NASA”), major aerospace and defense prime contractors as well as portions of the commercial sector.

Real Estate — includes the activities of the Company’s wholly-owned subsidiary Easton Development Company, LLC (“Easton”) related to the re-zoning, entitlement, sale, and leasing of the Company’s excess real estate assets. The Company is currently in the process of seeking zoning changes and other governmental approvals on its excess real estate assets to optimize its value.

A detailed description of the Company’s significant accounting policies can be found in the Company’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

AR1 Research and Development

Company-sponsored research and development ("R&D") expenses (reported as a component of cost of sales) are generally reimbursed via allocation of such expenses among all contracts and programs in progress under U.S. government contractual arrangements. The newest large liquid booster engine development project, the AR1, recorded $51.8 million of such reimbursable costs from inception through June 30, 2017. In February 2016, the U.S. Air Force selected Aerojet Rocketdyne and United Launch Alliance ("ULA") to share in a public-private partnership to develop jointly the AR1 engine. The total agreement is valued at $804.0 million with the U.S. Air Force investing two-thirds of the funding required to complete development of the AR1 engine by 2019. The work is expected to be completed no later than December 31, 2019. The U.S. Air Force has obligated $174.0 million with Aerojet Rocketdyne contributing $81.2 million and ULA contributing $5.8 million in cash and $3.4 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 proportionately as an offset to R&D expenses. In the event the Company records a receivable for a milestone prior to expending the prospective proportional share to be contributed by the Company, the amount is recorded as an accrued liability until earned. The AR1 inception to date project costs at June 30, 2017 were as follows (in millions):



AR1 R&D costs incurred	$	228.4
Less amounts funded by the U.S. Air Force	(135.3		)
Less amounts funded by ULA	(9.2		)
AR1 R&D costs net of reimbursements	83.9
AR1 R&D costs expensed and not applied to contracts	(32.1		)
Net AR1 R&D costs applied to contracts	$	51.8

Revenue Recognition

In the Company’s Aerospace and Defense segment, recognition of profit on long-term contracts requires the use of assumptions and estimates related to the contract value or 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 value 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 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 and 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. 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. When a change in estimate is determined to have an impact on contract profit, the Company 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 the Company’s operating results. The following table summarizes the impact of the change in significant contract accounting estimates on the Company’s Aerospace and Defense segment net sales accounted for under the percentage-of-completion method of accounting:



	Three months ended June 30,					Six months ended June 30,

Favorable (unfavorable) effect of the changes in contract estimates on basic and diluted net income per share	0.08		(0.03		)	0.11		(0.03		)

Recently Adopted Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (“FASB”) issued an amendment to the accounting guidance related to 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 guidance as of December 31, 2016 and no additional information was required to be presented as a result 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 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. Earlier application of this guidance is permitted but not before December 15, 2016. 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 includes 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 performance obligations using the cost-to-cost method. The unit-of-delivery method totaled 45% of net sales for the first half 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 year and will also result in the reclassification of contract related assets on the consolidated balance sheet. The Company does not expect the new guidance to change the total revenue or operating income on the related customer contracts, only the timing of when those revenues are recognized.

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.

(1) Less than 0.1 million of common share dilution impact from employee stock options and stock purchase plan for the second quarter and first half of fiscal 2017.

The following table sets forth the potentially dilutive securities excluded from the computation because their effect would have been anti-dilutive:



	Three months ended June 30,		Six months ended June 30,
	2017	2016	2017	2016
	(In millions)
4¹/₁₆% Debentures	—	9.4	—	9.4
Total potentially dilutive securities	—	9.4	—	9.4

The Company's 2.25% Convertible Senior Notes ("2¹/₄% Notes") were not included in the computation of diluted EPS for the second quarter and first half of fiscal 2017 because the market price of the common stock did not exceed the conversion price and the Company only expects the conversion premium for the 2¹/₄% Notes to be settled in common shares.

Note 3. Stock-Based Compensation

Total stock-based compensation expense by type of award was as follows:



	Three months ended June 30,				Six months ended June 30,
	2017		2016		2017		2016
	(In millions)
Stock appreciation rights	$	—	$	1.5	$	2.4	$	1.9

Employee stock purchase plan	0.1		0.1		0.3		0.2
Total stock-based compensation expense	$	3.4	$	3.1	$	10.2	$	5.4

Stock-based compensation in the first half of fiscal 2017 includes expenses associated with the accelerated vesting of stock awards to a former executive officer and the August 2016 stock award granted to the Executive Chairman that vests according to the attainment of share prices ranging from $22 per share to $27 per share of the Company's common stock.

Note 4. Balance Sheet Accounts

a. Fair Value of Financial Instruments

The accounting standards use a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The following are measured at fair value:



			Fair value measurement at June 30, 2017
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
	(In millions)
Money market funds	$	139.3	$	139.3	$	—	$	—

Money market funds	$	328.5	$	328.5	$	—	$	—

As of June 30, 2017, a summary of cash and cash equivalents and the grantor trust by investment type is as follows:



	Total		Cash and Cash Equivalents		Money Market Funds
	(In millions)
Cash and cash equivalents	$	413.6	$	281.5	$	132.1
Grantor trust (included as a component of other current and noncurrent assets)	7.2		—		7.2
	$	420.8	$	281.5	$	139.3

The carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation, and other accrued liabilities, approximate fair value because of their short maturities.

The estimated fair value and principal amount for the Company’s outstanding debt is presented below:



	Fair Value				Principal Amount
	June 30, 2017		December 31, 2016		June 30, 2017		December 31, 2016

_______

(1)

In December 2016, the Company notified holders of its 4¹/₁₆% Debentures that the Company would redeem, on February 3, 2017, all of their 4¹/₁₆% Debentures at a purchase price equal to 100% of the principal amount of the 4¹/₁₆% Debentures to be redeemed, plus any accrued and unpaid interest. In January 2017, $35.6 million of the 4¹/₁₆% Debentures (the entire amount outstanding as of December 31, 2016) were converted to 3.9 million shares of common stock.

The fair values of the 2¹/₄% Notes and 4¹/₁₆% Debentures were determined using broker quotes that are based on open markets for the Company’s debt securities (Level 2 securities). The term loan bore interest at variable rates, which adjusted based on market conditions, and its carrying value approximated fair value.

j. Redeemable Common Stock

The Company inadvertently failed to register with the Securities Exchange Commission ("SEC") the issuance of certain of its common shares in its defined contribution 401(k) employee benefit plan (the “Plan”). As 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. On May 30, 2017, 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 $3.3 million under the offer have been completed in July 2017 (see Note 13). As of June 30, 2017, the Company has classified 7,611 shares as mandatorily redeemable common stock. As of December 31, 2016, the Company had classified 0.1 million shares as redeemable common stock because the redemption feature was not within the control of the Company. The Company may also be subject to civil and other penalties by regulatory authorities as a result of the failure to register these shares. These shares have always been treated as outstanding for financial reporting purposes.

Note 5. Acquisition

On February 24, 2017, the Company closed on an agreement to purchase substantially all of the assets of Coleman Aerospace 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 to L3 for the purchase of Coleman is estimated to be $17.0 million, which includes $15.0 million of cash paid at closing and an estimated $2.0 million working capital adjustment to be paid in cash. 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 following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):



Current assets	$	12.0
Property, plant and equipment	3.9
Total tangible assets acquired	15.9
Intangible assets acquired	4.2
Deferred income taxes	0.3
Total assets acquired	20.4
Liabilities assumed, current	(5.2		)
Total identifiable net assets acquired	15.2
Goodwill (Consideration less total identifiable net assets acquired)	$	1.8

The purchase price allocation resulted in the recognition of $1.8 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.

The estimated fair value of Coleman's intangible assets acquired included the following:



	Gross Carrying Amount (in millions)		Amortization Period (years)
Trade name	$	0.5	8
Customer relationships	2.8		8
Developed technology	0.9		10
Total intangible assets	$	4.2

The acquisition of Coleman was not considered a significant business combination.

Note 6. Income Taxes



	Six months ended June 30,
	2017		2016
	(In millions)
Income tax provision	$	15.2	$	9.1

In the first half of fiscal 2017, the income tax provision was at an effective tax rate less than the federal statutory rate primarily due to tax benefits attributable to the expiration of statute limitations and excess tax benefits from the exercise and vesting of stock-based compensation awards.

In the first half of fiscal 2016, the income tax provision was at an effective tax rate greater than the federal statutory rate primarily due to certain expenditures which were permanently not deductible for tax purposes and state income taxes.

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 June 30, 2017, 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.

As of June 30, 2017, the total balance associated with uncertain income tax positions was a net liability of $28.4 million. Accrued interest and penalties related to uncertain income tax positions was $2.5 million at June 30, 2017. In the next twelve months, the Company believes it is reasonably possible that the unrecognized tax benefits could decrease by approximately $23.3 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.

Senior Credit Facility

On June 17, 2016, the Company entered into a new $750.0 million senior secured senior credit facility (the "Senior Credit Facility") with the lenders named therein and Bank of America Merrill Lynch as joint lead arranger and administrative agent. The Senior Credit Facility matures on June 17, 2021 and consists of (i) a $350.0 million revolving line of credit (the "Revolver") and (ii) a $400.0 million term loan (the "Term Loan"). Under the Revolver, up to an aggregate of $100.0 million is available for the issuance of letters of credit and up to an aggregate of $10.0 million is available for swingline loans. The Senior Credit Facility amends and replaces the prior $300.0 million credit facility which was set to mature in May 2019.

On the closing date, the Company borrowed $100.0 million of loans under the Revolver and used the proceeds to repay in full the $90.0 million of outstanding term loans under the prior credit facility, fees incurred for the Senior Credit Facility, and for general corporate purposes. As of June 30, 2017, the Company had $380.0 million outstanding under the Term Loan, zero borrowings under the Revolver, and had issued $39.1 million letters of credit.

The Term Loan and loans under the Revolver bear interest at LIBOR (or the base rate) plus an applicable margin ranging from 175 to 250 basis points based on the Company's leverage ratio (the "Consolidated Net Leverage Ratio") at the end of the most recent fiscal quarter. In addition to interest, the Company must also pay certain fees including (i) letter of credit fees ranging from 175 to 250 basis points per annum on the amount of issued but undrawn letters of credit and (ii) commitment fees ranging from 30 to 45 basis points per annum on the unused portion of the Revolver.

The Term Loan amortizes at a rate of 5.0% per annum of the original drawn amount starting on September 30, 2016, increasing to 7.5% per annum on September 30, 2018, and increasing to 10.0% per annum from September 30, 2020 to be paid in equal quarterly installments with any remaining amounts, along with outstanding borrowings under the Revolver, due on the maturity date. Outstanding borrowings under the Revolver and the Term Loan may be voluntarily repaid at any time, in whole or in part, without premium or penalty.

Subject to certain restrictions, all the obligations under the Senior Credit Facility are guaranteed by the Company and the existing and future material domestic subsidiaries, other than Easton (the "Guarantors"). As collateral security for the amount outstanding under the Senior Credit Facility and the guarantees thereof, the Company and the Guarantors (collectively, the "Loan Parties") have granted to the administrative agent for the benefit of the lenders: (i) certain equity interests of the Loan Parties; (ii) first priority liens on substantially all of the tangible and intangible personal property of the Loan Parties; and (iii) first priority liens on certain real properties located in Los Angeles, California, Culpepper, Virginia and Redmond, Washington (but excluding all other owned real properties).

The Senior Credit Facility contains covenants requiring the Company to (i) maintain an interest coverage ratio (the "Consolidated Interest Coverage Ratio") of not less than 3.00 to 1.00 and (ii) maintain a Consolidated Net Leverage Ratio not to exceed (a) 4.00 to 1.00 for periods ending June 30, 2017 through September 30, 2017; (b) 3.75 to 1.00 for periods ending from December 31, 2017 through September 30, 2018; and (c) 3.50 to 1.00 for periods ending from December 31, 2018 thereafter, provided that the maximum leverage ratio for all periods shall be increased by 0.50 to 1.00 for two quarters after consummation of a qualified acquisition.

The Company may generally make certain investments, redeem debt subordinated to the Senior Credit Facility and make certain restricted payments (such as stock repurchases) if the Company's Consolidated Net Leverage Ratio does not exceed 3.25 to 1.00 pro forma for such transaction. The Company is otherwise subject to customary covenants including limitations on asset sales, incurrence of additional debt, and limitations on certain investments and restricted payments.



Financial Covenant	Actual Ratios as of June 30, 2017	Required Ratios
Consolidated Interest Coverage Ratio, as defined under the Senior Credit Facility	12.40 to 1.00	Not less than: 3.00 to 1.00
Consolidated Net Leverage Ratio, as defined under the Senior Credit Facility	2.12 to 1.00	Not greater than: 4.00 to 1.00

The Company was in compliance with its financial and non-financial covenants as of June 30, 2017.

2.25% Convertible Senior Notes

On December 14, 2016, the Company issued $300.0 million aggregate principal amount of 2¼% Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended.

The Company separately accounted for the liability and equity components of the 2¼% Notes. The initial liability component of the 2¼% Notes was valued based on the present value of the future cash flows using an estimated borrowing rate at the date of the issuance for similar debt instruments without the conversion feature, which equals the effective interest rate of 5.8% on the liability component. The equity component, or debt discount, was initially valued equal to the principal value of the 2¼% Notes, less the present value of the future cash flows using an estimated borrowing rate at the date of the issuance for similar debt instruments without a conversion feature, which equated to the initial debt discount. The debt discount is being amortized as a non-cash charge to interest expense over the period from the issuance date through December 15, 2023.

The debt issuance costs of $5.8 million incurred in connection with the issuance of the 2¼% Notes were capitalized and bifurcated into deferred financing costs of $4.7 million and equity issuance costs of $1.1 million. The deferred financing costs are being amortized to interest expense from the issuance date through December 15, 2023.

The 2¼% Notes consisted of the following (in millions, except years, percentages, conversion rate, and conversion price):



	June 30, 2017			December 31, 2016
Carrying value, long-term	$	243.6		$	240.0
Unamortized discount and deferred financing costs	56.4			60.0
Principal amount	$	300.0		$	300.0
Carrying amount of equity component, net of equity issuance costs	$	54.5		$	54.5
Remaining amortization period (years)	6.5			7.0
Effective interest rate	5.8		%	5.8		%
Conversion rate (shares of common stock per $1,000 principal amount)	38.4615			38.4615
Conversion price (per share of common stock)	$	26.00		$	26.00

The following table presents the interest expense components for the 2¼% Notes for the first half of fiscal 2017 (in millions):



Interest expense-contractual interest	$	3.4
Interest expense-amortization of debt discount	3.3
Interest expense-amortization of deferred financing costs	0.3
	$	7.0

4.0625% Convertible Subordinated Debentures

As of June 30, 2017, the Company fully redeemed the outstanding principal amount of its 4¹/₁₆% Debentures. In December 2016, the Company notified holders of its 4¹/₁₆% Debentures that the Company would redeem, on February 3, 2017, all of their 4¹/₁₆% Debentures at a purchase price equal to 100% of the principal amount of the 4¹/₁₆% Debentures to be redeemed, plus any accrued and unpaid interest. In January 2017, $35.6 million of the 4¹/₁₆% Debentures (the entire amount outstanding as of December 31, 2016) were converted to 3.9 million shares of common stock.

Note 8. Commitments and Contingencies

a. 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 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 when a best estimate cannot be made, a minimum loss contingency amount 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 due to exposure to asbestos in building materials, products, or in manufacturing operations. The majority of cases are pending in Texas and Illinois. There were 64 asbestos cases pending as of June 30, 2017.

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. As of June 30, 2017, 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. 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 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 June 30, 2017.

Socorro

On May 12, 2015, a complaint for personal injuries, loss of consortium and punitive damages was filed by James Chavez, Andrew Baca, and their respective spouses, against Aerojet Rocketdyne and the Board of Regents of New Mexico Tech in the Seventh Judicial District, County of Socorro, New Mexico, James Chavez, et al., vs. Aerojet Rocketdyne, Inc., et al., Case No. D725CV201500047. Messrs. Chavez and Baca were employees of Aerotek, a contractor to Aerojet Rocketdyne, who were injured when excess energetic materials being managed by the Energetic Materials Research and Testing Center, a research division of New Mexico Tech, ignited in an unplanned manner. The complaint alleges causes of action based on negligence and negligence per se, strict liability, and willful, reckless and wanton conduct against Aerojet Rocketdyne, and seeks unspecified compensatory and punitive damages. The Company has filed its answer and discovery has commenced. Trial is scheduled for February 5, 2018. No liability for this matter has been recorded by the Company as of June 30, 2017.

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. A pre-hearing conference on the Company’s appeal of the citations was held on May 22, 2017. The judge set the next prehearing conference for September 11, 2017 to give sufficient time for settlement discussions.

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.

b. Environmental Matters

The Company is involved in over forty environmental matters under the Comprehensive Environmental Response Compensation and Liability Act, the Resource Conservation Recovery Act, and other federal, state, local, and foreign 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”) 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 fifteen 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 June 30, 2017, the aggregate range of these anticipated environmental costs was $338.9 million to $501.5 million and the accrued amount was $338.9 million. See Note 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”) 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. The 2002 PCD revision (a) separated the Sacramento site into multiple operable units to allow quicker implementation of remedy for critical areas; (b) required the Company to guarantee up to $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, and remedy construction associated with the operable units. In 2002, 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 by the California Regional Water Quality Control Board, Central Valley (“Central Valley

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 possibly off-site businesses and residences. The evaluation was conducted to determine whether and to what extent volatile organic compounds, such as trichloroethylene, are present in indoor air in 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 will include resampling a subset of the on-site buildings sampled in the first phase, as determined by EPA, and is anticipated to begin in August 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 investigate and remediate environmental contamination in the soils and the Central Valley RWQCB to investigate and remediate groundwater environmental contamination. On March 14, 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 expects 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.

As of June 30, 2017, the estimated range of anticipated costs discussed above for the Sacramento, California site was $204.7 million to $321.9 million and the accrued amount was $204.7 million included as a component of the Company’s environmental reserves. Expenditures associated with this matter are partially recoverable. See Note 8(c) below for further discussion on recoverability.

Baldwin Park Operable Unit (“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. Aerojet Rocketdyne, along with seven other PRPs (the "Cooperating Respondents”) signed a project agreement in late March 2002 with the San Gabriel Basin Water Quality Authority, the Main San Gabriel Basin Watermaster, and five water companies (the “Water Entities”). The project agreement, which had a term of fifteen years, became effective May 9, 2002 and terminated in May 2017. In April 2017, the parties executed a new project agreement which became operational on May 9, 2017. The new agreement has a ten year term and has similar provisions as the 2002 project agreement requiring 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 the other Cooperating Respondents entered into an interim allocation agreement, which was renewed effective March 28, 2014, that establishes the interim payment obligations, subject to final reallocation, of the Cooperating Respondents for the costs incurred pursuant to the project agreement. Under the interim allocation agreement, Aerojet Rocketdyne is responsible for approximately 70% (increased from approximately 68%) of all project costs. Since entering into the project agreement, two of the Cooperating Respondents, Huffy Corporation, and Fairchild Corporation (“Fairchild”), have filed for bankruptcy and are no longer participating in the project agreement. The interim allocation accounted for their shares. On September 30, 2014, another of the Cooperating Respondents, Reichhold, Inc. ("Reichhold"),

filed for bankruptcy under Chapter 11. Reichhold has stopped paying and Aerojet Rocketdyne increased its contribution for its portion of Reichhold’s share of the financial assurance. In the first quarter of fiscal 2017, Reichhold’s financial assurance was depleted and the remaining Cooperating Respondents assumed Reichhold’s share. Aerojet Rocketdyne and three of 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 approximately 74%.

As part of Aerojet Rocketdyne’s sale of its Electronics and Information Systems (“EIS”) business to Northrop in October 2001, the EPA approved a prospective purchaser agreement with Northrop to absolve it of 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 June 30, 2017, the estimated range of anticipated costs was $121.4 million to $159.2 million and the accrued amount was $121.4 million included as a component of the Company’s environmental reserves. Expenditures associated with this matter are partially recoverable. See Note 8(c) below 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 June 30, 2017, the estimated range of the Company's share of anticipated costs for the Wabash, Indiana site was $0.3 million to $0.7 million and the accrued amount was $0.3 million. None of the expenditures related to this matter are recoverable from the U.S. government.

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. 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 to design, construct, and implement the remedy.

A summary of the Company’s environmental reserve activity is shown below:



	Aerojet Rocketdyne- Sacramento			Aerojet Rocketdyne- BPOU			Other Aerojet Rocketdyne Sites			Total Aerojet Rocketdyne			Other (1)			Total Environmental Reserve
	(In millions)
December 31, 2016	$	210.1		$	126.8		$	8.5		$	345.4		$	4.3		$	349.7
Additions	6.8			1.8			0.3			8.9			0.5			9.4
Expenditures	(12.2		)	(7.2		)	(0.7		)	(20.1		)	(0.1		)	(20.2		)

______

(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”) 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”) 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 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”). The Company has met with ARC and responded to the ARC Claim on June 23, 2017. Certain costs related to the ARC Claim may be allocable to Aerojet Rocketdyne and will be determined in conjunction with the Company’s evaluation and ultimate resolution of the ARC Claim.

Estimated Recoveries

On January 12, 1999, Aerojet Rocketdyne and the U.S. government implemented the October 1997 Agreement in Principle (“Global Settlement”) resolving certain prior environmental and facility disagreements, with retroactive effect to December 1, 1998. Under the Global Settlement, Aerojet Rocketdyne and 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. Additionally, in conjunction with the sale of the EIS business in 2001, Aerojet Rocketdyne entered into an agreement with Northrop (the “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 and a cumulative limitation. The current annual billing limitation to Northrop is $6.0 million.

Most of the environmental costs are incurred by the Company's Aerospace and Defense segment, and certain of these future costs are allowable to be included in the Company’s contracts with the U.S. government and allocable to Northrop until the cumulative expenditure limitation is reached. Excluding the receivable from Northrop of $67.5 million discussed below, the Company currently estimates approximately 24% of its future Aerospace and Defense segment environmental costs will not likely be reimbursable and are expensed.

Allowable environmental costs are charged to the Company’s contracts 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 under U.S. government contracts and programs.

Pursuant to the Northrop Agreement, environmental expenditures to be reimbursed are subject to annual limitations and the total reimbursements are limited to cumulative expenditure limitation of $189.7 million. A summary of the Northrop Agreement activity is shown below (in millions):



Total reimbursable costs under the Northrop Agreement	$	189.7
Amount reimbursed to the Company through June 30, 2017	(122.2		)
Potential future cost reimbursements available	67.5
Less: Receivable from Northrop included in the unaudited condensed consolidated balance sheet as of June 30, 2017	(67.5		)
Potential future recoverable amounts available under the Northrop Agreement	$	—

While the Company is currently seeking 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.

Environmental reserves and estimated recoveries impact to unaudited condensed consolidated statements of operations

The expenses associated with adjustments to the environmental reserves are recorded as a component of other expense, net in the unaudited condensed consolidated statements of operations. Summarized financial information for the impact of environmental reserves and recoveries to the unaudited condensed consolidated statements of operations is set forth below:



	Three months ended June 30,				Six months ended June 30,
	2017		2016		2017		2016
	(In millions)
Estimated recoverable amounts under U.S. government contracts	$	3.8	$	1.7	$	7.7	$	6.3
Expense to unaudited condensed consolidated statement of operations	0.9		0.2		1.7		0.5
Total environmental reserve adjustments	$	4.7	$	1.9	$	9.4	$	6.8

Note 9. Arrangements with Off-Balance Sheet Risk

As of June 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 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 issues purchase orders 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 a cost-plus contract is terminated.

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. Cost Reduction Plans

During fiscal 2015, the Company initiated the first phase ("Phase I") of the competitive improvement program (the "CIP”) comprised of activities and initiatives aimed at reducing costs in order for the Company 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 Phase II (“Phase II”) of the Company’s previously announced CIP. Pursuant to Phase II, the Company plans to expand its CIP and further consolidate its Sacramento, California, and Gainesville, Virginia sites while centralizing and expanding its existing presence in Huntsville, Alabama. The Company currently estimates that it 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). The Company has incurred $63.2 million through June 30, 2017 including $29.5 million in capital expenditures. A summary of the Company's Phase I and II reserve activity is shown below:



	Severance			Retention			Total
	(In millions)
December 31, 2016	$	6.8		$	2.1		$	8.9
Accrual	33.3			0.6			33.9
Payments	(1.2		)	(0.2		)	(1.4		)
June 30, 2017	$	38.9		$	2.5		$	41.4

The costs associated with Phase I and II will be a component of the Company’s U.S. government forward pricing rates, and therefore, will be recovered through the pricing of the Company’s products and services to the U.S. government. In addition to the employee-related Phase I and II obligations, the Company incurred non-cash accelerated depreciation expense of $2.2 million and $0.4 million in the first half of fiscal 2017 and 2016, respectively, associated with changes in the estimated useful lives of long-lived assets.

Note 11. Retirement Benefits

Pension Benefits

The Company's defined benefit pension plan future benefit accrual was discontinued in fiscal 2009. As of 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 approximately $76.0 million to its tax-qualified defined benefit pension plan in fiscal 2017 of which $37.0 million is expected to be recoverable in its U.S. government contracts in fiscal 2017 with the remaining $39.0 million being potentially recoverable in its U.S. government contracts in the future. The Company has funded $18.6 million to its tax-qualified defined benefit pension plan in the first half of fiscal 2017 and in the third and fourth quarters of fiscal 2017 expects to fund $48.6 million and $8.8 million, respectively. 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.

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 Company’s 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 under the Company’s U.S. government contracts.

Components of retirement benefit expense (benefit) are:

Note 12. Operating Segments and Related Disclosures

The Company’s operations are organized into two operating segments based on different products and customer bases: Aerospace and Defense, and Real Estate.

The Company evaluates its 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 unusual items relating to the segment operations. Segment performance excludes corporate income and expenses, legacy income or expenses, unusual items not related to the segment operations, interest expense, interest income, and income taxes.

Customers that represented more than 10% of net sales for the periods presented are as follows:

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 Company,” “we,” “our” and “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”).

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 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, 2016, and periodic reports subsequently filed with the Securities and Exchange Commission (“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:

Aerospace and Defense — includes the operations of our wholly-owned subsidiary Aerojet Rocketdyne, Inc. (“Aerojet Rocketdyne”), a leading technology-based designer, developer and manufacturer of aerospace and defense products and systems for the United States (“U.S.”) government, including the Department of Defense (“DoD”), the National Aeronautics and Space Administration (“NASA”), major aerospace and defense prime contractors as well as portions of the commercial sector.

Real Estate — includes the activities of our wholly-owned subsidiary Easton Development Company, LLC (“Easton”) related to the re-zoning, entitlement, sale, and leasing of our excess real estate assets. We currently are in the process of seeking zoning changes and other governmental approvals on our excess real estate assets to optimize their value.

A summary of the significant financial highlights for the second quarter of fiscal 2017 which management uses to evaluate our operating performance and financial condition is presented below.


•	Net sales for the second quarter of fiscal 2017 totaled $459.6 million compared to $408.4 million for the second quarter of fiscal 2016.


•	Net income for the second quarter of fiscal 2017 was $24.3 million, or $0.32 diluted income per share, compared to net income of $5.9 million, or $0.09 diluted income per share, for the second quarter of fiscal 2016.


•	Adjusted EBITDAP (Non-GAAP measure*) for the second quarter of fiscal 2017 was $70.0 million, or 15.2% of net sales, compared to $47.5 million, or 11.6% of net sales, for the second quarter of fiscal 2016.


•	Segment performance before environmental remediation provision adjustments, retirement benefits, net, and unusual items (Non-GAAP measure*) was $60.2 million for the second quarter of fiscal 2017, compared to $40.8 million for the second quarter of fiscal 2016.


•	Cash provided by operating activities in the second quarter of fiscal 2017 totaled $40.8 million compared to $35.8 million of cash provided by operating activities in the second quarter of fiscal 2016.


•	As of June 30, 2017, we had $2.1 billion of funded backlog compared to $2.3 billion as of December 31, 2016.

_________

* We provide Non-GAAP measures as a supplement to financial results based on GAAP. 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 of Non-GAAP Financial Measures.”

We are operating in an environment that is characterized by both increasing complexity in the global security environment and continuing worldwide economic pressures. A significant component of our strategy in this environment is to focus on 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: 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.

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” 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.

Sales to the U.S. government and its agencies, including sales to our significant customers disclosed below, were as follows:



	Percentage of net sales
Three months ended June 30, 2017	93	%
Three months ended June 30, 2016	89	%
Six months ended June 30, 2017	93	%
Six months ended June 30, 2016	90	%

The RS-25 program, which is comprised of several contracts and included in U.S. government sales, represented 15% and 12% of net sales for the second quarter of fiscal 2017 and 2016, respectively. In addition, the RS-25 program represented 16% and 12% of net sales for the first half of fiscal 2017 and 2016, respectively. The Terminal High Altitude Area Defense (“THAAD”) program, which is comprised of several contracts and included in U.S. government sales, represented 11% and 15% of net sales for the second quarter of fiscal 2017 and 2016, respectively. In addition, the THAAD program represented 9% and 14% of net sales for the first half of fiscal 2017 and 2016, respectively. The Standard Missile program, which is comprised of several contracts and included in U.S. government sales, was less than 10% of net sales for the second quarter and first half of fiscal 2017. The Standard Missile program represented 10% and 9% of net sales for the second quarter and first half of fiscal 2016, respectively.

Customers that represented more than 10% of net sales for the periods presented were as follows:



	Three months ended June 30,				Six months ended June 30,
	2017		2016		2017		2016
Lockheed Martin Corporation	24	%	34	%	21	%	31	%
United Launch Alliance	23	%	17	%	23	%	19	%
NASA	18	%	13	%	18	%	13	%
Raytheon Company	14	%	19	%	16	%	18	%

Our sales to each of the major customers listed above involve several product lines and programs.

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 follow the cycle of general public policy and political support for this type of funding. Moreover, although our contracts often contemplate that our services will be performed over a period of several years, the U.S. Congress must appropriate funds for a given program and the U.S. President must sign into law such appropriations legislation each government fiscal year (“GFY”) and may significantly increase, decrease or eliminate, funding for 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.

Even with overall budget levels set for GFY 2017, Congress was not able to pass a full year appropriation for either the DoD or NASA prior to the start of GFY 2017 on October 1, 2016. As a result, Congress passed a short-term Continuing Resolution (“CR”) to fund the U.S. government until December 9, 2016. After the November U.S. presidential election, at the request of the Trump Administration, Congress passed another CR through April 28, 2017 to allow the new Administration to shape federal spending, and a third CR for one week through May 5, 2017 to finalize negotiations and a passage of GFY Omnibus Appropriations bill. 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. The Trump Administration has signaled strong support for nuclear modernization and missile defense.

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

In March 2015, we launched Phase I of the CIP ("Phase I") comprised of activities and initiatives aimed at reducing costs in order for us to continue to compete successfully. The company-wide initiative is being undertaken after a comprehensive assessment of our product portfolio to underpin Aerojet Rocketdyne’s technological and competitive leadership in our markets through continued research and development. Phase I is composed of three major components: (i) facilities optimization and footprint reduction; (ii) product affordability; and (iii) reduced administrative and overhead costs. The Phase I costs consist primarily of severance and other employee related costs totaling approximately $25.0 million, operating facility costs totaling approximately $19.0 million, $38.0 million for other costs relating to product re-qualification, knowledge transfer and other CIP implementation costs, and $31.0 million of capital expenditures.

On April 6, 2017, the Board of Directors approved Phase II of the CIP ("Phase II"). Pursuant to Phase II, we plan to expand our CIP and further consolidate our Sacramento, California, and Gainesville, Virginia sites while centralizing and expanding our existing presence in Huntsville, Alabama. By 2019, we expect to have incurred Phase II restructuring and related costs of $122.1 million (before any anticipated Phase II incentives to be finalized with state and local authorities and recoveries through the pricing of our U.S. government contracts), consisting of employee related costs of $65.2 million, facility costs of approximately $36.2 million, and $20.7 million for other costs relating to product requalification and knowledge transfer.

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 $63.2 million through June 30, 2017 including $29.5 million in capital expenditures.

Environmental Matters

Our current and former business operations are subject to, and affected by, federal, state, local, and foreign 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.

A summary of our recoverable amounts, environmental reserves, and estimated range of liability as of June 30, 2017 is presented below:



	Recoverable Amounts (1)		Environmental Reserves		Estimated Range of Liability
	(In millions)
Sacramento	$	154.5	$	204.7	$204.7 - $321.9
Baldwin Park Operable Unit	91.7		121.4		121.4 - 159.2
Other Aerojet Rocketdyne sites	8.1		8.1		8.1 - 13.9
Other sites	0.6		4.7		4.7 - 6.5
Total	$	254.9	$	338.9	$338.9 - $501.5

_____


(1)	Excludes the receivable from Northrop Grumman Corporation (“Northrop”) of $67.5 million as of June 30, 2017 related to environmental costs already paid (and therefore not reserved) by the Company in prior years and reimbursable under our agreement with Northrop.

Most of our environmental costs are incurred by our Aerospace and Defense segment, and certain of these future costs are allowable to be included in our contracts with the U.S. government. The cumulative expenditure limitation under our agreement with Northrop was reached on June 30, 2017. See Note 8(b) and (c) of the Notes to Unaudited Condensed Consolidated Financial Statements.

Capital Structure

We have a substantial amount of debt for which we are required to make interest and principal payments. Interest on long-term financing is not a recoverable cost under our U.S. government contracts. As of June 30, 2017, we had $680.0 million of debt principal outstanding. The fair value of the debt outstanding at June 30, 2017 was $698.3 million.

Retirement Benefits

We expect to make cash contributions of approximately $76.0 million to our tax-qualified defined benefit pension plan in fiscal 2017 of which $37.0 million is expected to be recoverable in our U.S. government contracts in fiscal 2017 with the remaining $39.0 million being potentially recoverable in our U.S. government contracts in the future. We have funded $18.6 million to our tax-qualified defined benefit pension plan in the first half of fiscal 2017 and in the third and fourth quarters of fiscal 2017 we expect to fund $48.6 million and $8.8 million, respectively. 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.

The funded status of our retirement benefit plans may be adversely affected by investment experience, 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 our retirement benefit 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 plans could be higher than we expect.

Additionally, the level of returns on retirement benefit assets, changes in interest rates, changes in legislation, and other factors affect our financial results. The timing of recognition of retirement benefit expense or income in our financial statements differs from the timing of the required funding under the Pension Protection Act or the amount of funding that can be recorded in our overhead rates through our U.S. government contracting business.

Results of Operations

	(In millions)
Net sales:	$	459.6	$	408.4	$	51.2	$	864.9	$	765.3	$	99.6

* Primary reason for change. The increase in net sales was primarily due to an increase of $72.9 million in space programs primarily driven by (i) the RS-25 program development and integration effort in support of the SLS development program; (ii) increased deliveries on the RL10 program; and (iii) the Coleman Aerospace acquisition partially offset by a decrease of $23.8 million in defense programs primarily driven by the timing of deliveries on the THAAD and Standard Missile programs.

** Primary reason for change. The increase in net sales was primarily due to an increase of $131.3 million in space programs primarily driven by (i) the RS-25 program development and integration effort in support of the SLS development program; (ii) increased deliveries on the Atlas V program; and (iii) the Coleman Aerospace acquisition partially offset by a decrease of $31.9 million in defense programs primarily driven by the timing of deliveries on the THAAD and PAC-3 programs.

Cost of sales	$	383.9		$	356.5		$	27.4	$	736.6		$	666.2		$	70.4

* Primary reason for change. The decrease in cost of sales as a percentage of net sales excluding retirement benefits was primarily due to the following (i) favorable contract performance with increased sales volume on the RS-68 program as a result of lower program costs and labor efficiencies and (ii) favorable contract performance on the THAAD program as a result of management reserve retirements due to reduced program risks and cost reductions.

** Primary reason for change. The decrease in cost of sales as a percentage of net sales excluding retirement benefits was primarily due to the following (i) favorable contract performance on the RL10 program as a result of lower program costs and management reserve reductions due to ongoing program efficiencies and (ii) favorable contract performance on the THAAD program as a result of management reserve retirements due to reduced program risks and cost reductions partially offset by cost growth and manufacturing inefficiencies in the first half of fiscal 2017 on electric propulsion contracts.

SG&A	$	14.7		$	13.6		$	1.1	$	33.2		$	25.2		$	8.0

* Primary reason for change. SG&A expense was essentially unchanged in the second quarter of fiscal 2017 compared to the second quarter of fiscal 2016.

** Primary reason for change. The increase in SG&A expense was primarily driven by an increase of $4.8 million in stock-based compensation primarily a result of the accelerated vesting of stock awards to a former executive officer and the August 2016 stock award granted to the Executive Chairman that vests according to the attainment of share prices ranging from $22 per share to $27 per share of our common stock.

First half of fiscal 2017 Activity:

We recorded $1.9 million ($1.3 million during the second quarter of fiscal 2017) of realized gains, net of interest associated with the failure to register with the SEC the issuance of certain of our common shares under the defined contribution 401(k) employee benefit plan. On May 30, 2017, we 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 $3.3 million under the offer have been completed in July 2017.

We recorded $1.0 million of costs related to the acquisition of Coleman Aerospace from L3 Technologies, Inc. (see Note 5 of the Notes to Unaudited Condensed Consolidated Financial Statements).

First half of fiscal 2016 Activity:

We recorded $0.2 million of realized gains, net of interest associated with the failure to register with the SEC the issuance of certain of our common shares under the defined contribution 401(k) employee benefit plan.

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").

* Primary reason for change. The decrease in interest expense was primarily due to the redemption of the 7¹/₈% Senior Secured Notes in the third quarter of fiscal 2016 and the conversion of 4¹/₁₆% Convertible Subordinated Debentures (“4¹/₁₆% Debentures”) to common shares. The decrease was partially offset by interest expense on the debt incurred on the Senior Credit Facility at a variable interest rate of 3.48% as of June 30, 2017 and the issuance of the 2¹/₄% Convertible Senior Notes ("2¹/₄% Notes") in December 2016 at an effective interest rate of 5.8%.

** Primary reason for change. The decrease in interest expense was primarily due to the retirement of the principal amount of our delayed draw term loan in the first quarter of fiscal 2016, the redemption of the 7¹/₈% Senior Secured Notes in the third quarter of fiscal 2016, and the conversion of 4¹/₁₆% Debentures to common shares. The decrease was partially offset by interest expense on the debt incurred on the Senior Credit Facility at a variable interest rate of 3.48% as of June 30, 2017 and the issuance of the 2¹/₄% Notes in December 2016 at an effective interest rate of 5.8%.

Income Tax provision:

The income tax provision was as follows:



	Six months ended June 30,
	2017		2016
	(In millions)
Income tax provision	$	15.2	$	9.1

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 June 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.

See Note 6 of the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion on uncertain income tax positions.

Retirement Benefits:

Components of retirement benefit expense are:



	Three months ended June 30,						Six months ended June 30,
	2017			2016			2017			2016
	(In millions)
Service cost	$	3.8		$	3.4		$	7.5		$	6.9
Interest cost on benefit obligation	14.7			16.5			29.5			33.0
Assumed return on plan assets	(16.2		)	(17.6		)	(32.3		)	(35.1		)
Amortization of prior service credits	0.1			(0.2		)	—			(0.5		)
Recognized net actuarial losses	15.9			15.1			31.9			30.1
Retirement benefits	$	18.3		$	17.2		$	36.6		$	34.4

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.

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.

Segment margin before environmental remediation provision adjustments, retirement benefits, net and unusual items increased primarily due to the following (i) favorable contract performance with increased sales volume on the RS-68 program as a result of lower program costs and labor efficiencies and (ii) favorable contract performance on the THAAD program as a result of management reserve retirements due to reduced program risks and cost reductions.

Segment margin before environmental remediation provision adjustments, retirement benefits, net and unusual items increased primarily due to the following (i) favorable contract performance on the RL10 program as a result of lower program costs and management reserve reductions due to ongoing program efficiencies and (ii) favorable contract performance on the THAAD program as a result of management reserve retirements due to reduced program risks and cost reductions partially offset by losses in the current period on the electric propulsion contracts as we continue to work towards resolving design challenges.

A summary of our backlog is as follows:



	June 30, 2017		December 31, 2016
	(In billions)
Funded backlog	$	2.1	$	2.3
Unfunded backlog	2.2		2.2
Total contract backlog	$	4.3	$	4.5

Total backlog includes both funded backlog (unfilled orders for which funding is authorized, appropriated and contractually obligated by the customer) and unfunded backlog (firm orders for which funding has not been appropriated). Indefinite delivery and quantity contracts and unexercised options are not reported in total backlog. Backlog is subject to funding delays or program restructurings/cancellations which are beyond our control. Of our June 30, 2017 total contract backlog, approximately 46%, or $2.0 billion, is expected to be filled within one year as compared to 38%, or $1.7 billion, at

December 31, 2016. Backlog has declined from December 31, 2016 primarily due to the timing of large multi-year awards. This decline was anticipated and may continue as we recognize sales under contracts with large multi-year awards, such as the $1.2 billion award for RS-25 engine restart received in November 2015 and continuing through November 2024. The nature and timing of large multi-year awards can create variability in our funded and total contract backlog.

* Primary reason for change. Net sales and segment performance consist primarily of rental property operations.

Use of Non-GAAP Financial Measures

In addition to segment performance (discussed above), we provide the Non-GAAP financial measure of our operational performance called Adjusted EBITDAP. We use this metric to measure our operating performance. We believe that to effectively compare core operating performance from period to period, the metric should exclude items relating to retirement benefits (pension and postretirement benefits), significant non-cash expenses, the impacts of financing decisions on earnings, and items incurred outside the ordinary, on-going and customary course of our operations. Accordingly, we define Adjusted EBITDAP as GAAP income before income taxes adjusted to exclude interest expense, interest income, depreciation and amortization, retirement benefits net of cash funding to our tax-qualified defined benefit pension plan that are recoverable under our U.S. government contracts, and unusual items which we do not believe are reflective of such ordinary, on-going and customary activities. Adjusted EBITDAP does not represent, and should not be considered an alternative to, net income, as determined in accordance with GAAP.

_____

(1) Retirement benefits are net of cash funding to our tax-qualified defined benefit pension plan which are recoverable costs under our U.S. government contracts. Our recoverable tax-qualified pension costs in the second quarter of fiscal 2017 and 2016 totaled $9.3 million and $6.9 million, respectively. Our recoverable tax-qualified pension costs in the first half of fiscal 2017 and 2016 totaled $18.6 million and $13.8 million, respectively.

In addition to segment performance and Adjusted EBITDAP, we provide the Non-GAAP financial measures of free cash flow and net debt. We use these financial measures, both in presenting our results to stakeholders and the investment community, and in our internal evaluation and management of the business. Management believes that these financial measures are useful because it presents our business using the same tools that management uses to evaluate progress in achieving our performance metrics for annual cash and long-term compensation incentive plans.

____________

(1) Free Cash Flow, a Non-GAAP financial measure, is defined as cash flow from operating activities less capital expenditures. Free Cash Flow should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to cash flows from operations presented in accordance with GAAP. We believe Free Cash Flow is useful as it provides supplemental information to assist investors in viewing the business using the same tools that management uses to evaluate progress in achieving our goals.

Because our method for calculating the Non-GAAP measures may differ from other companies’ methods, the Non-GAAP measures presented above may not be comparable to similarly titled measures reported by other companies. These measures are not recognized in accordance with GAAP, and we do not intend for this information to be considered in isolation or as a substitute for GAAP measures.

Other Information

Recently Adopted Accounting Pronouncements

See Note 1 of the Notes to Unaudited Condensed Consolidated Financial Statements for information relating to our discussion of the effects of recent accounting pronouncements.

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, 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.

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 the contract value or 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 value 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 and 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. 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 net sales accounted for under the percentage-of-completion method of accounting:



	Three months ended June 30,					Six months ended June 30,

A detailed description of our significant accounting policies can be found in our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Arrangements with Off-Balance Sheet Risk

As of June 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.

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.

Liquidity and Capital Resources

Net Cash Provided by (Used in) Operating, Investing, and Financing Activities

The change in cash and cash equivalents was as follows:



	Six months ended June 30,
	2017			2016
	(In millions)
Net Cash Provided by Operating Activities	$	37.7		$	4.1
Net Cash Used in Investing Activities	(21.1		)	(19.5		)
Net Cash Used in Financing Activities	(13.3		)	(9.4		)
Net Increase (Decrease) in Cash and Cash Equivalents	$	3.3		$	(24.8	)

Net Cash Provided by Operating Activities

The $37.7 million of cash provided by operating activities in the first half of fiscal 2017 was primarily the result of $110.9 million of cash generated by the 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 $87.8 million in accounts receivables due to the timing of net sales and (ii) a decrease of $49.0 million in cash advances on long-term contracts, partially offset by a decrease of $20.7 million in inventories primarily due to a decrease in overhead costs. In addition, we received $21.3 million for income tax refunds in the first half of fiscal 2017.

The $4.1 million of cash provided by operating activities in the first half of fiscal 2016 was primarily the result of $75.3 million of cash generated by the 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 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 $37.0 million in cash advances on long-term contracts; (ii) an increase of $22.3 million in other current assets, net primarily related to income taxes; and (iii) a decrease of $13.7 million in other current liabilities. The funding of working capital was partially offset by an increase of $23.2 million in accounts payable due to the timing of payments.

Net Cash Used In Investing Activities

During the first half of fiscal 2017, we purchased Coleman Aerospace for $15.0 million.

During the first half of fiscal 2017 and 2016, we had capital expenditures of $6.1 million and $19.5 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 half of fiscal 2017, we had debt repayments of $10.0 million (see below). During the first half of fiscal 2016, we had debt repayments of $105.7 million.

Debt Activity and Covenants

Our debt principal activity since December 31, 2016 was as follows:



	December 31, 2016		Cash Payments			Non-cash Equity Conversion			June 30, 2017
	(In millions)
Term loan	$	390.0	$	(10.0	)	$	—		$	380.0
2¹/₄% Notes	300.0		—			—			300.0
4¹/₁₆% Debentures	35.6		—			(35.6		)	—
Total Debt and Borrowing Activity	$	725.6	$	(10.0	)	$	(35.6	)	$	680.0

Our Senior Credit Facility contains covenants requiring us to (i) maintain an interest coverage ratio (the "Consolidated Interest Coverage Ratio") of not less than 3.00 to 1.00 and (ii) maintain a leverage ratio ( the "Consolidated Net Leverage Ratio") not to exceed (a) 4.00 to 1.00 for periods ending June 30, 2017 through September 30, 2017; (b) 3.75 to 1.00 for periods ending from December 31, 2017 through September 30, 2018; and (c) 3.50 to 1.00 for periods ending from December 31, 2018 thereafter, provided that the maximum leverage ratio for all periods shall be increased by 0.50 to 1.00 for two quarters after consummation of a qualified acquisition. We may generally make certain investments, redeem debt subordinated to the Senior Credit Facility and make certain restricted payments (such as stock repurchases) if our Consolidated Net Leverage Ratio does not exceed 3.25 to 1.00 pro forma for such transaction. We are otherwise subject to customary covenants including limitations on asset sales, incurrence of additional debt, and limitations on certain investments and restricted payments.



Financial Covenant	Actual Ratios as of June 30, 2017	Required Ratios
Consolidated Interest Coverage Ratio, as defined under the Senior Credit Facility	12.40 to 1.00	Not less than: 3.00 to 1.00
Consolidated Net Leverage Ratio, as defined under the Senior Credit Facility	2.12 to 1.00	Not greater than: 4.00 to 1.00

We were in compliance with our financial and non-financial covenants as of June 30, 2017.

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 our revolving credit facility 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, and interest and principal payments on our debt. As of June 30, 2017, we had $310.9 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 June 30, 2017. 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 and to withstand unanticipated business volatility. We believe that cash generated 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. 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.

Potential future 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 future acquisitions. Other sources of capital could include the issuance of common and/or preferred stock, and the placement of debt. 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 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.

As disclosed in Notes 8(a) and 8(b) of the Notes to 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.

Major factors that could adversely impact our forecasted operating cash and our financial condition are described in the section “Risk Factors” in Item 1A of our Annual Report to the SEC on Form 10-K for the fiscal year ended December 31, 2016.

Forward-Looking Statements

Certain information contained in this report should be considered “forward-looking statements” as defined by Section 21E of the Private Securities Litigation Reform Act of 1995.

•	the release, explosion, or unplanned ignition of dangerous materials used in the Company's businesses;


•	loss of key qualified suppliers of technologies, components, and materials;


•	the funded status of the Company's defined benefit pension plan and the Company's obligation to make cash contributions in excess of the amount that the Company can recover in its current period overhead rates;


•	effects of changes in discount rates and actuarial estimates, actual returns on plan assets, and government regulations on defined benefit pension plans;


•	the possibility that environmental and other government regulations that impact the Company become more stringent or subject the Company to material liability in excess of its established reserves;


•	environmental claims related to the Company's current and former businesses and operations including the inability to protect or enforce previously executed environmental agreements;


•	reductions in the amount recoverable from environmental claims;


•	the results of significant litigation;


•	significant risk exposures and potential liabilities that are inadequately covered by indemnity or insurance;

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to our disclosures related to certain market risks as reported under Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report to the SEC on Form 10-K for the fiscal year ended December 31, 2016.

Interest Rate Risk

We are exposed to market risk principally due to changes in interest rates. Debt with interest rate risk includes borrowings under our Senior Credit Facility. Other than pension assets and liabilities, we do not have any significant exposure to interest rate risk related to our investments.

As of June 30, 2017, our debt principal amounts totaled $680.0 million: $300.0 million, or 44%, was at a fixed rate of 2.25%; and $380.0 million, or 56%, was at a variable rate of 3.48%.

The estimated fair value and principal amount of our outstanding debt is presented below:



	Fair Value				Principal Amount
	June 30, 2017		December 31, 2016		June 30, 2017		December 31, 2016
	(In millions)
Term loan	$	380.0	$	390.0	$	380.0	$	390.0
2¹/₄% Notes	318.3		294.9		300.0		300.0
4¹/₁₆% Debentures (1)	—		70.8		—		35.6
	$	698.3	$	755.7	$	680.0	$	725.6

In December 2016, we notified holders of our 4¹/₁₆% Debentures that we would redeem, on February 3, 2017, all of their 4¹/₁₆% Debentures at a purchase price equal to 100% of the principal amount of the 4¹/₁₆% Debentures to be redeemed, plus any accrued and unpaid interest. In January 2017, $35.6 million of the 4¹/₁₆% Debentures (the entire amount outstanding as of December 31, 2016) were converted to 3.9 million shares of common stock.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

Management has conducted an evaluation (with the participation of our Chief Executive Officer and Chief Financial Officer), of the effectiveness of the design and operation of the Company’s 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 June 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 not effective as of June 30, 2017.

Disclosure controls and procedures are designed to ensure that information required to be disclosed in company reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls 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 management, including the Company’s Chief Executive Officer and Chief 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 is in the process of improving and strengthening the internal controls related to income taxes which includes hiring additional tax resources (internal or external) and implementing additional controls to validate the completeness and accuracy of financial information utilized in our accounting for income taxes. During the first half of fiscal 2017, the Company hired key tax personnel, including a vice president overseeing the tax function, and transitioned to a new external service provider for the preparation of the quarterly tax provision and annual tax returns.

Changes in internal control over financial reporting

There 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.
