Accounting Policies [Abstract]

Summary of Significant Accounting Policies and Related Data

Basis of Consolidation. The consolidated financial statements include the balances of Apogee Enterprises, Inc. and its subsidiaries (Apogee, the Company or we) after elimination of intercompany balances and transactions. We consolidate variable interest entities where it has been determined that the Company is the primary beneficiary of those entities' operations.

Fiscal Year. Our fiscal year ends on the Saturday closest to the last day of February, or as determined by the Board of Directors. Fiscal 2018 and 2016 each consisted of 52 weeks, while fiscal 2017 consisted of 53 weeks. Our Brazilian subsidiary follows a calendar year-end and is consolidated on a two-month lag.

Accounting Estimates. The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates.

Cash Equivalents. Highly liquid investments with an original maturity of three months or less are included in cash equivalents and are stated at cost, which approximates fair value.

Marketable securities. Our marketable securities are classified as available for sale, and we test for other-than-temporary losses on a quarterly basis or whenever events or changes in circumstances indicate that the carrying amount of a security may not be recoverable. We consider all unrealized losses to be temporary in nature. We intend to hold our securities until the full principal amount can be recovered, and we have the ability to do so based on other sources of liquidity. Gross realized gains and losses are included in other income (expense) in our consolidated results of operations.

Inventories. Inventories, which consist primarily of purchased glass and aluminum, are valued at lower of cost or market using the first-in, first-out (FIFO) method.

Property, Plant and Equipment. Property, plant and equipment (PP&E) is recorded at cost. Significant improvements and renewals that extend the useful life of the asset are capitalized. Repairs and maintenance are charged to expense as incurred. When an asset is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any related gains or losses are included in selling, general and administrative expenses. Long-lived assets to be held and used, such as PP&E, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Depreciation is computed on a straight-line basis, based on the following estimated useful lives:



	Years
Buildings and improvements	10 to 25
Machinery and equipment	3 to 15
Office equipment and furniture	3 to 7

Goodwill and Intangible Assets. Goodwill represents the excess of the cost over the net tangible and identified intangible assets of acquired businesses. We evaluate goodwill for impairment annually at our year-end, or more frequently if impairment indicators exist. This year we elected to bypass the qualitative assessment process and to proceed directly to comparing the fair value of each of our reporting units to carrying value, including goodwill. If the fair value exceeds the carrying value, goodwill impairment is not indicated. Each of our nine business units represents a reporting unit for the goodwill impairment analysis. Based on our analysis, the estimated fair value of each reporting unit exceeded its carrying value and, therefore, goodwill impairment was not indicated. We have followed a consistent discounted cash flow methodology to evaluate goodwill in all periods presented.

We base our determination of fair value on a discounted cash flow methodology that involves significant judgment and projections of future performance. Assumptions about future revenues and expenses, capital expenditures and changes in working capital are based on the annual operating plan and long-term business plan for each business unit. These plans take into consideration numerous factors, including historical experience, anticipated future economic conditions and growth expectations for the industries and end markets in which we participate. Growth rates for revenues and operating profits vary for each reporting unit. The discount rate assumption for each reporting unit takes into consideration our assessment of risks inherent in the future cash flows of our business and an estimated weighted-average cost of capital.

Intangible assets with indefinite useful lives are tested for impairment annually at our year-end, or more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Fair value is measured using the relief-from-royalty method. This method assumes the trade name or mark has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue from the related asset, the appropriate royalty rate, and the weighted average cost of capital. The assessment of fair value involves significant judgment and projections about future performance. Based on our analysis, the fair value of each indefinite-lived asset exceeded the carrying amount.

Intangible assets with defined useful lives are amortized based on estimated useful lives ranging from 18 months to 20 years and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The estimated useful lives of all intangible assets are reviewed annually, and we have determined that the remaining lives were appropriate.

Self-Insurance. We obtain commercial insurance for potential losses for general liability, employment practices, workers' compensation, automobile liability, architect's and engineer's errors and omissions risk, product rework and other miscellaneous coverages. A substantial portion of this risk is retained on a self-insured basis through our wholly-owned insurance subsidiary. We establish a reserve for estimated ultimate losses on reported claims and those incurred but not yet reported utilizing actuarial projections. Reserves are classified within accrued or long-term self-insurance reserves based on expectations of when the estimated loss will be paid.

Additionally, we maintain a self-insurance reserve for health insurance programs offered to eligible employees, included within accrued self-insurance reserves. The reserve includes an estimate for losses on reported claims as well as for amounts incurred but not yet reported, based on historical trends.

Warranty. We are subject to claims associated with our products and services, principally as a result of disputes with our customers involving the performance or aesthetics of our architectural products and services. We reserve estimated exposures on known claims, as well as on a portion of anticipated claims for product warranty and rework costs, based on historical product liability claims as a ratio of sales. Our warranty reserves are included in other current and non-current liabilities based on the estimated timing of dispute resolution.

Environmental Liability. We recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated based on estimates by specialists and applicable law. Such estimates are based primarily on the estimated cost of investigation and remediation required, and the likelihood that, where applicable, other potentially responsible parties will not be able to fulfill their commitments at the sites where the Company may be jointly and severally liable. The reserve for environmental liabilities is included in other current and non-current liabilities in the consolidated balance sheets.

Foreign Currency. Local currencies are considered the functional currencies for our subsidiaries outside of the United States. Assets and liabilities of these subsidiaries are translated at the exchange rates at the balance sheet date. Income and expense items are translated using average monthly exchange rates. Translation adjustments are included in accumulated other comprehensive loss in the consolidated balance sheets.

Derivatives and Hedging Activities. We periodically enter into forward purchase foreign currency contracts, generally with an original maturity date of less than one year, to hedge foreign currency exchange rate risk. All derivative instruments within the scope of ASC 815, Derivatives and Hedging, are recorded on the consolidated balance sheet at fair value. All hedging instruments that qualify for hedge accounting are designated and effective as hedges. Instruments that do not qualify for hedge accounting are marked to market with changes recognized in current earnings. Cash flows from derivative instruments are classified in the statement of cash flows in the same category as the cash flows from the items subject to designated hedge or undesignated (economic) hedge relationships.We do not hold or issue derivative financial instruments for trading purposes and are not a party to leveraged derivatives.

Revenue Recognition. We recognize revenue when title has transferred, except within our Architectural Services segment and for one business within our Architectural Framing Systems segment, which enter into fixed-price contracts for projects typically performed over a 12- to 24-month timeframe. We record revenue for these contracts on a percentage-of-completion basis as we are able to reasonably estimate total contract revenue and total contract costs. We compare the total costs incurred to date to the total estimated costs for the contract, and record that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. We believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of accuracy in measuring revenue throughout the contract period. Provisions are established for estimated losses, if any, on uncompleted contracts in the period in which such losses are determined. Amounts representing contract change orders, claims or other items are included in contract revenue only upon customer approval. Approximately 22 percent, 26 percent and 25 percent of our consolidated net sales in fiscal 2018, 2017 and 2016, respectively, were recorded on a percentage-of-completion basis.

Revenue excludes sales taxes as the Company considers itself a pass-through conduit for collecting and remitting sales taxes.

Pricing and Sales Incentives. The Company records estimated reductions to revenue for customer programs and incentive offerings, including pricing arrangements, promotions and other volume-based incentives, at the later of the date revenue is recognized or the incentive is offered. Sales incentives given to customers are recorded as a reduction to net sales unless (1) the Company receives an identifiable benefit for goods or services in exchange for the consideration, and (2) the Company can reasonably estimate the fair value of the benefit received.

Shipping and Handling. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as revenue. Costs incurred by the Company for shipping and handling are reported as cost of sales.

Research and Development. Research and development costs are expensed as incurred within selling, general and administrative expenses, and were $14.0 million, $8.6 million and $8.0 million for fiscal 2018, 2017 and 2016, respectively. Of these amounts, $1.5 million, $2.2 million and $2.4 million, respectively, were focused primarily upon design of custom window and curtainwall systems in accordance with customer specifications and are included in cost of sales.

Advertising. Advertising costs are expensed as incurred within selling, general and administrative expenses, and were $1.4 million in fiscal 2018, $1.1 million in fiscal 2017 and $1.2 million in fiscal 2016.

Income Taxes. The Company recognizes deferred tax assets and liabilities based upon the future tax consequences of temporary differences between financial statement carrying amounts of assets and liabilities and their respective tax bases. See Note 14 for additional information regarding income taxes.

Subsequent Events. We have evaluated subsequent events for potential recognition and disclosure through the date of this filing and determined that there were no subsequent events that required recognition or disclosure in the consolidated financial statements.

New Accounting Standards. In February 2018, the Financial Accounting Standards Board (FASB), issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits a company to reclassify the disproportionate income tax effects of the 2017 Act on items within AOCI to retained earnings. The FASB refers to these amounts as “stranded tax effects.” The ASU also requires certain new disclosures, applicable for all companies. The guidance is effective for fiscal years beginning after December 15, 2018, and may be early adopted. We are evaluating the timing of adopting this standard, but do not expect it to have a significant impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging, which improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 (our fiscal 2020), with early adoption permitted. We have elected to early adopt ASU 2017-12, and the standard has been applied to derivative contracts entered into in fiscal 2018.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairment by requiring impairment charges to be based on the first step in the current two-step impairment test process. The new guidance eliminates the current requirement to calculate a goodwill impairment charge using step 2. The standard is applicable to impairment tests performed in periods beginning after December 15, 2019 (our fiscal 2020), with early adoption permitted. We elected to early adopt this standard for our fiscal 2018 goodwill impairment assessment process.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, and in November 2016, it issued 2016-18, Restricted Cash. Both standards provide guidance for presentation of certain topics within the statement of cash flows, including presenting restricted cash within cash and cash equivalents, and are intended to improve consistency in presentation. The new classification guidance is effective for fiscal years beginning after December 15, 2017 (our fiscal 2019), and is to be applied retrospectively for comparability across all periods. These standards may be adopted early, and we are considering the timing of adoption but we do not expect this guidance to have a significant impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which provides for a comprehensive change to lease accounting. The new standard requires that a lessee recognize a lease obligation liability and a right to use asset for virtually all leases of property, plant and equipment, subsequently amortized over the lease term. The new standard is effective for fiscal years beginning after December 15, 2018 (our fiscal 2020), with a modified retrospective transition. The adoption of this standard will result in reflecting assets and liabilities for the value of our leased property and equipment on our consolidated balance sheet, but it is not expected to have a significant impact on our consolidated results of operations.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Under the new standard, an entity recognizes revenue 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. This guidance is effective for annual reporting periods beginning after December 15, 2017, our fiscal 2019 and we adopted the standard beginning in our fiscal year 2019.


•	We adopted the guidance following a modified retrospective transition method, with a cumulative effect adjustment to opening retained earnings in fiscal 2019. We estimate this retained earnings adjustment to be approximately $3 to $5 million.


•	Some of our business units will continue to recognize revenue at the point in time when goods are shipped, as that represents when control is transferred to the customer. We also have business units that will continue to recognize revenue over time, following a cost-to-cost percentage of completion method for revenue recognition.

•

Two of our business units, representing approximately 38 percent of our total net sales, will change from recognizing revenue at a point in time to recognizing revenue over time, to better reflect transfer of control to the customer in line with the new guidance. We have determined measures of progress toward completion for each business, based on the contract terms and the facts and circumstances associated with the performance obligations of each business.

Acquisition

Acquisitions

EFCO

On June 12, 2017, we acquired 100 percent of the stock of EFCO Corporation, a privately-held U.S. manufacturer of architectural aluminum window, curtainwall, storefront and entrance systems for commercial construction projects, for approximately $192 million in cash. The acquisition was funded through our committed revolving credit facility, with $7.5 million of that amount payable in three annual installments beginning in June 2018. Subsequent to the acquistion, we received approximately $2 million through a working capital settlement. EFCO's results of operations have been included in our consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition, including $203.7 million of sales and $0.8 million of operating income. As of March 3, 2018, we had incurred approximately $5.1 million of acquisition-related costs associated with this transaction.

The assets and liabilities of EFCO were recorded in our consolidated balance sheet as of the acquisition date, at their respective fair values. Fair value is estimated based on one or a combination of income, cost and/or market approaches, as determined based on the nature of the asset or liability, and the level of inputs available. With respect to assets and liabilities, the determination of fair value requires management to make subjective judgments, including projections of future operating performance, the appropriate discount rate to apply and long-term growth rates (unobservable inputs classified as Level 3 inputs under the fair value hierarchy described in Note 5), which affect the amounts recorded in the purchase price allocation. The excess of the consideration transferred over the fair value of the identifiable assets, net of liabilities, is recorded as goodwill, which is indicative of the expected continued growth and development of EFCO. The purchase price allocation is based on the estimated fair values of assets acquired and liabilities assumed, including estimated acquired contract liabilities, as follows:



(In thousands)
Net working capital	$	7,689
Property, plant and equipment	44,641
Goodwill	84,162
Other intangible assets	71,500
Less: Long-term liabilities acquired, net	17,643
Net assets acquired	$	190,349

Other intangible assets reflect the following:



(In thousands)	Estimated fair value		Estimated useful life (in years)
Customer relationships	$	34,800	16
Tradename	32,400		Indefinite
Backlog	4,300		1.5
	$	71,500

These fair values are based on estimates and are subject to change, based on finalization of net working capital amounts.

Sotawall

On December 14, 2016, we acquired substantially all the assets of Sotawall, Inc. (now operating under the name Sotawall Limited or "Sotawall"), for approximately $138 million, funded by cash and short-term investments of approximately $73 million and by approximately $65 million of borrowings under our committed revolving line of credit. Sotawall specializes in the design, engineering, fabrication, assembly and installation of unitized curtainwall systems for industrial, commercial and institutional buildings, primarily serving the Canadian and northeastern U.S. geographic regions. Sotawall's results of operations have been included in the consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. Purchase accounting related to this acquisition was completed during the first quarter of fiscal 2018. Final purchase price allocation was as follows:



(In thousands)
Net working capital	$	10,682
Property, plant and equipment	7,993
Goodwill	21,380
Other intangible assets	94,630
Net assets acquired	$	134,685

The following table provides certain unaudited pro forma consolidated information for the combined company for the fourth quarters and fiscal years 2018 and 2017, as if the EFCO and Sotawall acquisitions were consummated pursuant to each of their respective same terms at the beginning of the fiscal year preceding their respective acquisition dates.

Unaudited pro forma information has been provided for comparative purposes only and the information does not necessarily reflect what the combined results of operations actually would have been had the acquisitions occurred at the beginning of fiscal year 2017. The information does not reflect the effect of any synergies or integration costs that we expect to result from the acquisitions.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Financial assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1 (unadjusted quoted prices in active markets for identical assets or liabilities); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data). We do not have any Level 3 assets or liabilities.

Financial assets and liabilities measured at fair value on a recurring basis were:



(In thousands)	Quoted Prices in Active Markets (Level 1)		Other Observable Inputs (Level 2)		Total Fair Value

Long-term securities
Municipal bonds	—		9,041		9,041
Total assets at fair value	$	4,423	$	15,089	$	19,512

Cash equivalents

Fair value of money market funds was determined based on quoted prices for identical assets in active markets. Commercial paper was measured at fair value using inputs based on quoted prices for similar securities in active markets.

Short- and long-term securities

Municipal bonds were measured at fair value based on market prices from recent trades of similar securities and are classified as short-term or long-term based on maturity date. Mutual funds were measured at fair value based on quoted prices for identical assets in active markets.

Foreign currency instruments. We periodically enter into forward purchase foreign currency contracts, generally with an original maturity date of less than one year, to hedge foreign currency exchange rate risk. In the fourth quarter, we held foreign exchange forward contracts with a U.S. dollar notional value of $15.2 million, with the objective of reducing the exposure to fluctuations in the Canadian dollar and the Euro. The fair value of these contracts was a net liability of $0.1 million at year-end. These forward contracts are measured at fair value using unobservable market inputs, such as quotations on forward foreign exchange points and foreign currency exchange rates, and would be classified as Level 2 within the fair value hierarchy above.

Debt

Debt Disclosure [Abstract]

Debt

In June 2017, we amended and restated the credit agreement governing our credit facility, which has a maturity date of November 2021, to increase the amount of the revolving credit facility to $335.0 million. We had $195.0 million outstanding on our revolving credit facility as of March 3, 2018 and $45.0 million outstanding as of March 4, 2017. As defined within our facility, we have two financial covenants that require us to stay below a maximum debt-to-EBITDA ratio and maintain a minimum ratio of interest expense-to-EBITDA. Both ratios are computed quarterly, with EBITDA calculated on a rolling four-quarter basis. If the Company is not in compliance with either of these covenants, our credit facility may be terminated and/or any amounts then outstanding may be declared immediately due and payable. At March 3, 2018, we were in compliance with both financial covenants. We have the ability to issue letters of credit of up to $70.0 million under this credit facility, the outstanding amounts of which decrease the available commitment. At March 3, 2018, $116.5 million was available under this credit facility.

Debt at March 3, 2018 also included $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043 and $0.5 million of long-term debt in Canada that matures in August 2022. The fair value of the industrial revenue bonds approximated carrying value at March 3, 2018, due to the variable interest rates on these instruments. The bonds would be classified as Level 2 within the fair value hierarchy described in Note 5.

We also maintain two Canadian revolving credit facilities totaling $12.0 million Canadian dollars. No borrowings were outstanding under the facilities as of March 3, 2018 or March 4, 2017.

Compensation and Retirement Disclosure [Abstract]

Employee Benefit Plans

401(k) Retirement Plan

The Company sponsors a single 401(k) retirement plan covering substantially all full-time, non-union employees, as well as union employees at two of its manufacturing facilities. Under the plan, employees are allowed to contribute up to 60 percent of eligible earnings to the plan, up to statutory limits. The Company contributes a match of 100 percent of the first one percent contributed and 50 percent of the next five percent contributed on eligible compensation that non-union employees contribute and according to contract terms for union employees. The Company match was $7.5 million in fiscal 2018, $6.2 million in fiscal 2017 and $5.4 million in fiscal 2016.

Deferred Compensation Plan

The Company maintains a plan that allows participants to defer compensation. The deferred compensation liability was $10.7 million and $7.7 million at March 3, 2018 and March 4, 2017, respectively. The Company has investments in corporate-owned life insurance policies (COLI) of $10.8 million and money market funds (classified as cash equivalents) of $0.4 million with the intention of utilizing them as long-term funding sources for this plan. The COLI assets are recorded at their net cash surrender values and are included in other non-current assets in the consolidated balance sheet.

Plans under Collective Bargaining Agreements

We contribute to various multi-employer union retirement plans, which provide retirement benefits to the majority of our union employees; none of the plans are considered significant. The total contribution to these plans in fiscal 2018, 2017 and 2016 was $2.9 million, $3.9 million and $3.6 million, respectively.

Pension Plan

The Company sponsors the Tubelite Inc. Hourly Employees' Pension Plan, a defined-benefit pension plan that was frozen to new entrants in fiscal 2004, with no additional benefits accruing to plan participants after such time.

Officers' Supplemental Executive Retirement Plan (SERP)

The Company sponsors an unfunded SERP for the benefit of certain executives, a defined-benefit pension plan that was frozen to new entrants in fiscal 2009, with no additional benefits accruing to plan participants after such time.

Obligations and Funded Status of Defined-Benefit Pension Plans

The following tables present reconciliations of the benefit obligation of the defined-benefit pension plans and the funded status of the defined-benefit pension plans. The Tubelite plan uses a measurement date as of the calendar month-end closest to our fiscal year-end, while the SERP uses a measurement date aligned with our fiscal year-end.

Total net periodic pension benefit cost is expected to be approximately $0.7 million in fiscal 2019. The estimated net actuarial loss for the defined-benefit pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost for fiscal 2019 is $0.2 million, net of tax benefit.

Additional Information

Assumptions



Benefit Obligation Weighted-Average Assumptions	2018		2017		2016
Discount rate	3.80	%	3.80	%	3.85	%



Net Periodic Benefit Expense Weighted-Average Assumptions	2018		2017		2016
Discount rate	3.80	%	3.85	%	3.60	%
Expected long-term rate of return on assets	2.00	%	2.00	%	2.00	%

Discount rate. The discount rate reflects the current rate at which the defined-benefit plans' pension liabilities could be effectively settled at the end of the year based on the measurement date. The discount rate was determined by matching the expected benefit payments to payments from the Principal Discount Yield Curve. There are no known or anticipated changes in the discount rate assumption that will have a significant impact on pension expense in fiscal 2019.

Expected return on assets. To develop the expected long-term rate of return on assets, we considered historical long-term rates of return achieved by the plan investments, the plan's investment strategy, and current and projected market conditions. In accordance with its policy, the assets of the Tubelite plan are invested in a short-term bond fund and carried at fair value based on prices from recent trades of similar securities, which would be classified as Level 2 in the valuation hierarchy. We do not maintain assets intended for the future use of the SERP.

Contributions

Company contributions to the plans for each of fiscal 2018 and 2017 totaled $1.0 million, which equaled or exceeded the minimum funding requirement.

Estimated Future Benefit Payments

The following benefit payments, which reflect expected future service, are expected to be paid by the plans:

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Operating lease commitments. As of March 3, 2018, the Company was obligated under non-cancelable operating leases for buildings and equipment. Certain leases provide for increased rentals based upon increases in real estate taxes or operating costs. Future minimum rental payments under non-cancelable operating leases are:



(In thousands)	2019		2020		2021		2022		2023		Thereafter		Total
Total minimum payments	$	14,385	$	12,440	$	9,095	$	7,090	$	6,199	$	14,110	$	63,319

Total rental expense, including operating leases and short-term equipment rentals, was $21.8 million, $16.9 million and $15.5 million in fiscal 2018, 2017 and 2016, respectively. We lease the property that holds Sotawall's principal facilities from a company owned by the President of Sotawall. Total rent paid for this facility was approximately $2.6 million in fiscal 2018, and the future minimum lease commitment is $14.9 million.

At March 3, 2018, we had one sale and leaseback agreement for equipment that provides an option to purchase the equipment at projected future fair market value upon expiration of the lease in 2021. The lease is classified as an operating lease in accordance with applicable financial accounting standards. The Company has a deferred gain of $1.3 million under the sale and leaseback transaction, which is included in the balance sheet as other current and non-current liabilities. The average annual lease payment over the remaining life of the lease is $1.0 million.

Bond commitments. In the ordinary course of business, predominantly in the Company’s Architectural Services segment, the Company is required to provide surety or performance bonds that commit payments to its customers for any non-performance. At March 3, 2018, $238.6 million of the Company’s backlog was bonded by performance bonds with a face value of $519.3 million. Performance bonds do not have stated expiration dates, as the Company is released from the bonds upon completion of the contract and any related warranty period. The Company has never been required to make any payments related to these performance-based bonds with respect to any of its current portfolio of businesses.

Warranties. We reserve estimated exposures on known claims, as well as on a portion of anticipated claims for product warranty and rework costs based on historical product liability claims as a ratio of sales. Claims are deducted from the accrual when paid. Factors that could have an impact on the warranty accrual in any given period include the following: changes in manufacturing quality, shifts in product mix and any significant changes in sales volume. A warranty rollforward follows:



(In thousands)	2018			2017
Balance at beginning of period	$	21,933		$	16,340
Additional accruals	4,643			11,499
Acquired reserves	5,663			—
Claims paid	(9,722		)	(5,906		)
Balance at end of period	$	22,517		$	21,933

Letters of credit. At March 3, 2018, we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The total value of letters of credit under which we were obligated as of March 3, 2018 was approximately $23.5 million, all of which have been issued under our credit facility. Total availability under our credit facility is reduced by borrowings and by letters of credit issued under the facility.

Purchase obligations. Purchase obligations for raw material commitments and capital expenditures totaled $183.9 million as of March 3, 2018.

Environmental liability. In fiscal 2008, we acquired one manufacturing facility which has certain historical environmental conditions. We are working to remediate these conditions; remediation has been conducted without significant disruption to our operations. Our liability for these remediation activities was $1.3 million and $1.4 million at March 3, 2018 and March 4, 2017, respectively.

New Markets Tax Credit transactions. In June 2016, we entered into a transaction with a subsidiary of Wells Fargo (WF) under a qualified New Markets Tax Credit (NMTC) program related to an investment in plant and equipment within our Architectural Glass segment. The NMTC transaction is subject to 100 percent tax credit recapture for a period of seven years. Therefore, proceeds received in exchange for the transfer of the tax credits will be recognized as earnings in fiscal 2024, if the expected tax benefits are delivered without risk of recapture to each bank and our performance obligations are relieved. In exchange for substantially all the benefits derived from tax credits, WF contributed $6.0 million into the project. This is included within other non-current liabilities on our consolidated balance sheets. Direct and incremental costs of $4.5 million are included in other non-current assets on our consolidated balance sheet and will be recognized in proportion to the recognition of the related profits. Variable-interest entities were created as a result of the structure of these transactions, which have been included within our consolidated financial statements as the banks do not have a material interest in the underlying economics of the projects.

Litigation. The Company is a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company’s construction supply and services businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is subject to litigation arising out of general liability, employment practices, workers' compensation and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Share-Based Compensation

We have a 2009 Stock Incentive Plan and a 2009 Non-Employee Director Stock Incentive Plan (the Plans) that provide for the issuance of 1,888,000 and 350,000 shares, respectively, for various forms of stock-based compensation to employees and non-employee directors. Awards under these Plans may be in the form of incentive stock options (to employees only), nonstatutory options or stock-settled stock appreciation rights (SARs), all of which are granted with an exercise price equal to the fair market value of the Company’s stock at the date of award. We are also authorized to issue nonvested share awards and nonvested share unit awards under the Plans. Issued SARs vest over a three-year period and options issued to non-employee directors vest at the end of six months, both with a 10-year term. Nonvested share awards and nonvested share unit awards generally vest over a two, three or four-year period.

We had a 2002 Omnibus Stock Incentive Plan, which was terminated in June 2009; no new grants may be made under this plan, although exercises of SARs and options previously granted thereunder will still occur in accordance with the terms of the various grants.

Total stock-based compensation expense under all Plans included in the results of operations was $6.2 million for fiscal 2018, $6.0 million for fiscal 2017 and $4.9 million for 2016. We elect to account for any forfeitures as they occur.

Stock Options and SARs

There were no stock options or SARs issued in any fiscal year presented. Activity for the current year is summarized as follows:



	Number of Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value at Year-End
Outstanding at March 4, 2017	229,901		$	9.90
Awards exercised	(100,000	)	8.34
Outstanding and exercisable at March 3, 2018	129,901		$	11.10	2.8 Years	$	4,269,503

Cash proceeds from the exercise of stock options were $0.8 million, $1.9 million and $1.6 million for fiscal 2018, 2017 and 2016, respectively. The aggregate intrinsic value of securities exercised (the amount by which the stock price on the date of exercise exceeded the stock price of the award on the date of grant) was $4.8 million, $6.0 million and $7.5 million in fiscal 2018, 2017 and 2016, respectively.

Nonvested Share Awards and Units

The following table summarizes nonvested share activity for fiscal 2018:



	Number of Shares and Units		Weighted Average Grant Date Fair Value
March 4, 2017	279,204		$	44.80
Granted	135,416		54.61
Vested	(130,940	)	45.29
Canceled	(17,500	)	49.65
March 3, 2018	266,180		$	49.22

At March 3, 2018, there was $6.9 million of total unrecognized compensation cost related to nonvested share and nonvested share unit awards, which is expected to be recognized over a weighted average period of approximately 19 months. The total fair value of shares vested during fiscal 2018 was $7.1 million.

The estimated effective tax rate for fiscal 2018 declined 2.4 percentage points from fiscal 2017 primarily due to the U.S. Tax Cuts and Jobs Act ("the Act"), which was enacted in December 2017. Among other things, the Act reduces the U.S. federal corporate tax rate from 35 percent to 21 percent beginning January 1, 2018, resulting in a blended tax rate for our fiscal 2018. It also requires the revaluation of deferred taxes, which generated a tax benefit in the quarter of $4.1 million.

Also in December 2017, the SEC issued Staff Accounting Bulletin (“SAB 118”), which provides guidance on accounting for tax effects of the Act. SAB 118 provides a measurement period that should not extend beyond one year from the enactment date of the Act for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate to be included in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provision of the tax laws that were in effect immediately before the enactment of the Act. The FASB provided additional guidance to address the accounting for the effects of the provisions related to the taxation of Global Intangible Low-Taxed Income, or GILTI, noting that companies should make an accounting policy election to recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to include the tax expense in the year it is incurred. We have not completed our analysis of the effects of the GILTI provisions and will further consider the accounting policy election within the measurement period as provided for under SEC Staff Accounting Bulletin 118.

In fiscal 2017, we recorded a net tax benefit of $1.9 million on a distribution from our Brazilian operation.

The Company has U.S. federal tax credits as well as state net operating loss carryforwards with a tax effect of $6.3 million. A valuation allowance of $4.3 million has been established for these net operating loss carryforwards due to the uncertainty of the use of the tax benefits in future periods.

The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, Canada, Brazil and other international jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years prior to fiscal 2015, or state and local income tax examinations for years prior to fiscal 2010. The Company is not currently under U.S. federal examination for years subsequent to fiscal 2014, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions.

The Company considers the earnings of its non-U.S. subsidiaries to be indefinitely invested outside of the U.S. on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs and specific plans for reinvestment of those subsidiary earnings. Should the Company decide to repatriate foreign earnings, it would need to adjust the income tax provision in the period it was determined that the earnings will no longer be indefinitely invested outside the U.S.

If we were to prevail on all unrecognized tax benefits recorded, $2.4 million, $2.1 million and $2.7 million for fiscal 2018, 2017 and 2016, respectively, would benefit the effective tax rate. Also included in the balance of unrecognized tax benefits for fiscal 2018, 2017 and 2016, are $2.3 million, $2.0 million and $1.8 million, respectively, of tax benefits that, if recognized, would result in adjustments to deferred taxes.

Penalties and interest related to unrecognized tax benefits are recorded in income tax expense. For fiscal 2018, we accrued penalties and interest related to unrecognized tax benefits of $0.4 million. For fiscal 2017 and 2016, the accrual was $0.4 million and $0.5 million, respectively.

The following table provides a reconciliation of the total amounts of gross unrecognized tax benefits:



(In thousands)	2018			2017			2016
Gross unrecognized tax benefits at beginning of year	$	4,075		$	4,512		$	4,491

Gross unrecognized tax benefits at end of year	$	4,705		$	4,075		$	4,512

The total liability for unrecognized tax benefits is expected to decrease by approximately $0.5 million during fiscal 2019 due to lapsing of statutes.

Earnings Per Share [Abstract]

Earnings per Share

Basic earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding, including the dilutive effects of stock options, SARs and nonvested shares. The following table presents a reconciliation of the share amounts used in the computation of basic and diluted earnings per share:

Due to the varying combinations and integration of individual window, storefront and curtainwall systems, the Company has determined that it is impractical to report product revenues generated by class of product beyond the segment revenues currently reported.

Segment operating income is equal to net sales less cost of sales and operating expenses. Operating income does not include interest expense or a provision for income taxes. Corporate and other includes miscellaneous corporate activity not allocable to our segments. Identifiable assets for Corporate and other include all short- and long-term available-for-sale securities.

The following table presents net sales, based on the location in which the sale originated, and long-lived assets, representing property, plant and equipment, net of related depreciation, by geographic region.

•	We adopted the guidance following a modified retrospective transition method, with a cumulative effect adjustment to opening retained earnings in fiscal 2019. We estimate this retained earnings adjustment to be approximately $3 to $5 million.


•	Some of our business units will continue to recognize revenue at the point in time when goods are shipped, as that represents when control is transferred to the customer. We also have business units that will continue to recognize revenue over time, following a cost-to-cost percentage of completion method for revenue recognition.
