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, we, us, our or the Company) after elimination of intercompany balances and transactions. We consolidate variable interest entities related to our New Market Tax Credit transactions as it has been determined that the Company is the primary beneficiary of those entities' operations (refer to Note 10 for more information).

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 2019 and 2018 each consisted of 52 weeks, while fiscal 2017 consisted of 53 weeks.

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. Marketable securities are included in other current and non-current assets on the consolidated balance sheets and 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 estimated useful lives of 10 to 25 years for buildings and improvements; 3 to 15 years for machinery and equipment; and 3 to 7 years for office equipment and furniture.

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. 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 reporting 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.

Definite-lived intangible assets 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 to provide coverage for potential losses in areas such as employment practices, workers' compensation, directors and officers, automobile, architect's and engineer's errors and omissions, product rework and general liability. 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 and project-related contingencies

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. We also reserve for estimated exposures on other claims as they are known and reasonably estimable. Reserves are included in other current and non-current liabilities based on the estimated timing of dispute resolution.

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 sheets 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 statements 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

On March 4, 2018, we adopted ASC 606, Revenue from Contracts with Customers, and as a result, made updates to our significant accounting policy for revenue recognition. We generate revenue from the design, engineering and fabrication of architectural glass, curtainwall, window, storefront and entrance systems, and from installing those products on commercial buildings. We also manufacture value-added glass and acrylic products. Due to the diverse nature of our operations and various types of contracts with customers, we have businesses that recognize revenue over time and businesses that recognize revenue at a point in time.

During fiscal 2019, approximately 44 percent of our total revenue is recognized at the time products are shipped from our manufacturing facilities, which is when control is transferred to our customer, consistent with past practices. These businesses do not generate contract-related assets or liabilities. Variable consideration associated with these contracts and orders, generally related to early pay discounts or volume rebates, is not considered significant.

We also have three businesses which operate under long-term, fixed-price contracts, representing approximately 34 percent of our total revenue in the current year. This includes one business which changed revenue recognition practices due to the adoption of the new guidance, moving from recognizing revenue at shipment to an over-time method of revenue recognition. The contracts for these businesses have a single, bundled performance obligation, as these businesses generally provide interrelated products and services and integrate these products and services into a combined output specified by the customer. The customer obtains control of this combined output, generally integrated window systems or installed window and curtainwall systems, over time. We measure progress on these contracts following an input method, by comparing total costs incurred to-date to the total estimated costs for the contract, and record that proportion of the total contract price as revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. We believe this method of recognizing revenue is consistent with our progress in satisfying our contract obligations.

Due to the nature of the work required under these long-term contracts, the estimation of total revenue and costs incurred throughout a project is subject to many variables and requires significant judgment. It is common for these contracts to contain potential bonuses or penalties which are generally awarded or charged upon certain project milestones or cost or timing targets, and can be based on customer discretion. We estimate variable consideration at the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on our assessments of anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

Long-term contracts are often modified to account for changes in contract specifications and requirements of work to be performed. We consider contract modifications to exist when the modification, generally through a change order, either creates new or changes existing enforceable rights and obligations, and we evaluate these types of modifications to determine whether they may be considered distinct performance obligations. In many cases, these contract modifications are for goods or services that are not distinct from the existing contract, due to the significant integration service provided in the context of the contract. Therefore, these modifications are accounted for as part of the existing contract. The effect of a contract modification on the transaction price and our measure of progress is recognized as an adjustment to revenue, generally on a cumulative catch-up basis.

Typically, under these fixed-price contracts, we bill our customers following an agreed-upon schedule based on work performed. Because the progress billings do not generally correspond to our measurement of revenue on a contract, we generate contract assets when we have recognized revenue in excess of the amount billed to the customer. We generate contract liabilities when we have billed the customer in excess of revenue recognized on a contract.

Finally, we have one business, making up approximately 22 percent of our total revenue in the current year, that recognizes revenue following an over-time output method based upon units produced. The customer is considered to have control over the products at the time of production, as the products are highly customized with no alternative use, and we have an enforceable right to payment for performance completed over the production period. We believe this over-time output method of recognizing revenue reasonably depicts the fulfillment of our performance obligations under our contracts. Previously, this business recognized revenue at the time of shipment. Billings still occur upon shipment. Therefore, contract assets are generated for the unbilled amounts on contracts when production is complete. Variable consideration associated with these orders, generally related to early pay discounts, is not considered significant.

As outlined within the new accounting guidance, we elected several practical expedients in our transition to ASC 606:


•	We have made an accounting policy election to account for shipping and handling activities that occur after control of the related goods transfers to the customer as fulfillment activities, instead of assessing such activities as performance obligations.


•	We have made an accounting policy election to exclude from the transaction price all sales taxes related to revenue-producing transactions that are collected from the customer for a government authority.


•	We generally expense incremental costs of obtaining a contract when incurred because the amortization period would be less than one year. These costs primarily relate to sales commissions and are included in selling, general and administrative expenses.


•	We have not adjusted contract price for a significant financing component, as we expect the period between when our goods and services are transferred to the customer and when the customer pays for those goods and services to be less than a year.

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

Shipping and handling

Amounts billed to a customer in a sales transaction related to shipping and handling 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 and were $19.5 million, $14.0 million and $8.6 million for fiscal 2019, 2018 and 2017, respectively. Of these amounts, $6.5 million, $1.5 million and $2.2 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. The remainder of the expense is included within selling, general and administrative expenses.

Advertising

Advertising costs are expensed as incurred within selling, general and administrative expenses, and were $1.5 million in fiscal 2019, $1.4 million in fiscal 2018 and $1.1 million in fiscal 2017.

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 13 for additional information regarding income taxes.

Subsequent events

We have evaluated subsequent events for potential recognition and disclosure through the date of this filing. Subsequent to the end of the year, we purchased 437,671 shares of stock under our authorized share repurchase program, at a total cost of $16.2 million.

Adoption of new accounting standards

We adopted the new guidance in ASC 606, Revenue from Contracts with Customers, using the modified retrospective transition method applied to those contracts which were not complete as of March 4, 2018, the beginning of our fiscal year 2019. Prior period amounts were not adjusted and therefore continue to be reported in accordance with the accounting guidance and our accounting policies in effect for those periods.

Representing the cumulative effect of adopting ASC 606, we recorded a $3.0 million increase to the opening balance of retained earnings as of March 4, 2018. For the three- and twelve-month periods ending March 2, 2019, the application of the new accounting guidance had the following impact on our consolidated financial statements:



	Three Months Ended March 2, 2019						Twelve Months Ended March 2, 2019

Other current liabilities							83,159		81,467
Retained earnings							367,597		363,672

These changes are primarily a result of the transition of certain of our businesses from recognizing revenue at the time of shipment to over-time methods of revenue recognition.

In the first quarter of fiscal 2019, we also adopted ASU 2016-15, Statement of Cash Flows, and ASU 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 they have been applied retrospectively for comparability across all periods. The adoption of these standards did not have a significant impact on our consolidated statements of cash flows.

In the first quarter of fiscal 2019, we elected to early adopt ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard permits a company to reclassify the disproportionate income tax effects of the 2017 Tax Cuts and Jobs Act on items within accumulated other comprehensive income ("AOCI") to retained earnings. The FASB refers to these amounts as “stranded tax effects.” As a result of this adoption, we reclassified income tax effects of $0.7 million resulting from tax reform from AOCI to retained earnings following a portfolio approach. These stranded tax effects are derived from the deferred tax balances on our pension obligations as a result of the lower U.S. federal corporate tax rate.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. Among other areas, the new guidance changes the current accounting related to the classification and measurement of certain equity investments and changes certain disclosures associated with the fair value of financial instruments. Most notably, ASU 2016-01 requires that equity investments be measured at fair value with changes in fair value recognized in net income as opposed to other comprehensive income. For equity investments considered to be without a readily determinable fair value (and which do not qualify for the net asset value practical expedient), entities will be permitted to elect a measurement alternative and measure the investment at cost less impairment plus or minus observable price changes (in orderly transactions). We adopted ASU 2016-01 in our fiscal year 2019, which did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as we have historically held limited amounts of equity investments, and we have not elected the fair value option with respect to material financial liabilities.

In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU changes how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. Under the new standard, only the service cost component of net periodic benefit cost would be included in operating expenses while all other net periodic benefit costs components would be reported outside of operating income. We adopted this standard in fiscal 2019 and as a result, costs of $0.5 million were included within other expense in our consolidated results of operations. The components of our net periodic defined benefit pension costs are presented in Note 9.

Accounting standards not yet adopted

In February 2016, the FASB issued ASU 2016-02, Leases, which provides for comprehensive changes to lease accounting. The 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.

We adopted this standard in the first quarter of fiscal 2020, following the modified retrospective application approach. We are substantially complete with our implementation efforts, which have included identification and analysis of our lease portfolio, analysis and evaluation of the new reporting and disclosure requirements of the new guidance, and an evaluation of our lease-related processes and internal controls. The adoption of this standard will result in reflecting a right-of-use asset and lease liability on our consolidated balance sheet in the first quarter of fiscal 2020 of approximately $50 million. In adopting the new standard, we elected the package of practical expedients, as well as the practical expedient not to separate nonlease components from lease components. We do not expect this standard to have a significant impact on our consolidated results of operations, consolidated statements of cash flows, our liquidity, or on our debt covenant compliance under our current agreements. We have identified new and updated existing internal controls and process to support measurement, recognition and disclosure under this new standard, but such changes were not deemed to be material to our overall system of internal controls.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope. The new standard introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. This ASU is effective for our fiscal year 2021. Entities are required to apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We are currently assessing this ASU’s impact on our consolidated financial statements.

Revenue, Receivables and Contract Assets and Liabilities

The following table disaggregates total revenue by timing of recognition (see Note 15 for disclosure of revenue by segment):



	Three Months Ended		Twelve Months Ended
(In thousands)	March 2, 2019		March 2, 2019

Recognized over time	204,462		779,280
Total	$	346,255	$	1,402,637

Receivables

Trade and construction accounts receivable consist of amounts billed and due from customers. The amounts due are stated at their estimated net realizable value. We maintain an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected. This allowance is based on an assessment of customer creditworthiness, historical payment experience and the age of outstanding receivables. Retainage on construction contracts represents amounts withheld by our customers on long-term projects until the project reaches a level of completion at which amounts are released.



(In thousands)	2019			2018
Trade accounts	$	145,693		$	157,562

Less: allowance for doubtful accounts	(4,372		)	(1,530		)
Net receivables	$	192,767		$	211,852

Contract assets and liabilities

Contract assets consist of retainage, costs and earnings in excess of billings and other unbilled amounts typically generated when revenue recognized exceeds the amount billed to the customer. Contract liabilities consist of billings in excess of costs and earnings and other deferred revenue on contracts. Retainage is classified within receivables and deferred revenue is classified within other current liabilities on our consolidated balance sheets.

The time period between when performance obligations are complete and when payment is due is not significant. In certain of our businesses that recognize revenue over time, progress billings follow an agreed-upon schedule of values, and retainage is withheld by the customer until the project reaches a level of completion where amounts are released.



(In thousands)	March 2, 2019		March 3, 2018
Contract assets	$	87,491	$	30,508
Contract liabilities	24,083		20,120

The increase in contract assets was primarily due to additional businesses recognizing revenue in advance of billings, as a result of changing accounting policies for revenue recognition upon adoption of ASC 606 and the timing of costs incurred in advance of billing on a large project. The increase in contract liabilities was due to timing of project activity within our businesses that operate under long-term contracts.

During fiscal 2019, we recognized revenue of $10.4 million related to contract liabilities at March 4, 2018, and revenue of $5.9 million related to performance obligations satisfied in previous periods due to changes in contract estimates. For the fourth quarter of fiscal 2019, we did not recognize any revenue related to contract liabilities at March 4, 2018, and recognized revenue of $2.1 million related to performance obligations satisfied in previous periods due to changes in contract estimates.

Some of our contracts have an expected duration of longer than a year, with performance obligations extending over that timeframe. Generally these contracts are in our businesses with long-term contracts which recognize revenue over time. As of March 2, 2019, the transaction price associated with unsatisfied performance obligations was approximately $734.1 million. The performance obligations are expected to be satisfied, and the corresponding revenue to be recognized, over the following estimated time periods:

We have a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism), which holds these bonds. Prism insures a portion of our general liability, workers' compensation and automobile liability risks using reinsurance agreements to meet statutory requirements. The reinsurance carrier requires Prism to maintain fixed-maturity investments, which are generally high-quality municipal and corporate bonds, for the purpose of providing collateral for Prism's obligations under the reinsurance agreements.

The amortized cost and estimated fair values of our municipal and corporate bonds at March 2, 2019, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities, as borrowers may have the right to call or prepay obligations with or without penalty.

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:

Total assets at fair value	$	2,901	$	9,453	$	12,354

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. At March 2, 2019, we held foreign exchange forward contracts with a U.S. dollar notional value of $17.5 million, with the objective of reducing the exposure to fluctuations in the Canadian dollar and the Euro. The fair value of these contracts at year-end was a net liability of $0.5 million. 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.

Nonrecurring fair value measurements

Certain assets are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances. These include certain long-lived assets that are written down to estimated fair value when they are determined to be impaired, utilizing a valuation approach incorporating Level 3 inputs. See Note 7 for information regarding this impairment.

In fiscal 2019, we tested indefinite-lived intangible assets for impairment and determined that the fair value of one of our tradenames, with a carrying value of $32.4 million, was below its carrying amount by $3.1 million and therefore we recorded this impairment charge within selling, general and administrative expenses. We continue to conclude that the useful life of our indefinite-lived intangible assets is appropriate.

Amortization expense on definite-lived intangible assets was $12.7 million, $17.8 million and $4.0 million in fiscal 2019, 2018 and 2017, respectively.

Debt Disclosure [Abstract]

Debt

We maintain a committed revolving credit facility with maximum borrowings of up to $335.0 million, maturing in November 2021. Outstanding borrowings under our committed revolving credit facility were $225.0 million, as of March 2, 2019 and $195.0 million outstanding as of March 3, 2018. Under this facility, we are subject to 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 2, 2019, 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 2, 2019, $84.9 million was available under this credit facility.

Debt at March 2, 2019 also included $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043 and $0.4 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 2, 2019, 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 demand revolving credit facilities totaling $12.0 million Canadian dollars. No borrowings were outstanding under the facilities as of March 2, 2019 or March 3, 2018. Borrowings under the facilities are made available at the sole discretion of the lender and are payable on demand, with interest at rates specified in the credit agreements for the demand facilities.

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 $8.0 million in fiscal 2019, $7.5 million in fiscal 2018 and $6.2 million in fiscal 2017.

The Company maintains a plan that allows participants to defer compensation. The deferred compensation liability was $12.1 million and $10.7 million at March 2, 2019 and March 3, 2018, respectively. The Company has investments in corporate-owned life insurance policies (COLI) of $13.2 million and money market funds (classified as cash equivalents) of $0.6 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 2019, 2018 and 2017 was $4.9 million, $2.9 million and $3.9 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, 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.

Additional Information

Assumptions



Benefit Obligation Weighted-Average Assumptions	2019		2018		2017
Discount rate	3.80	%	3.80	%	3.80	%



Net Periodic Benefit Expense Weighted-Average Assumptions	2019		2018		2017
Discount rate	3.85	%	3.80	%	3.85	%
Expected long-term rate of return on assets	4.50	%	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 2020.

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. During fiscal 2019, the assets of the Tubelite plan were moved from investment in a short-term bond fund to various duration fixed income funds. The investments are 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 fiscal 2019 were $2.1 million and for fiscal 2018 were $1.0 million, which equaled or exceeded the minimum funding requirements.

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 2, 2019, the Company was obligated under non-cancelable operating leases for buildings and equipment. Certain leases provide for increased rental payments based upon increases in real estate taxes or operating costs. Future minimum rental payments under non-cancelable operating leases are:



(In thousands)	2020		2021		2022		2023		2024		Thereafter		Total
Total minimum payments	$	14,888	$	11,787	$	9,669	$	8,772	$	6,735	$	16,806	$	68,657

Total rental expense, including operating leases and short-term equipment rentals, was $25.1 million, $21.8 million and $16.9 million in fiscal 2019, 2018 and 2017, respectively. We lease the property that holds Sotawall's principal facilities from a company owned by an officer of Sotawall. Total rent paid for this facility was approximately $3.2 million in fiscal 2019, and the future minimum lease commitment is $12.7 million.

At March 2, 2019, we had one sale-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 $0.8 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 Architectural Services and Architectural Framing Systems segments, we are required to provide surety or performance bonds that commit payments to our customers for any non-performance. At March 2, 2019, $313.2 million of our backlog was bonded by these types of bonds with a face value of $570.6 million. These bonds do not have stated expiration dates, as we are released from the bonds upon completion of the contract. We have not been required to make any payments under these bonds with respect to our existing businesses.

Warranty and project-related contingencies

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. Claim costs 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, changes in product mix and any significant changes in sales volume. A warranty rollforward follows:



(In thousands)	2019			2018
Balance at beginning of period	$	22,517		$	21,933
Additional accruals	5,552			4,643
Acquired reserves	—			5,663
Claims paid	(11,332		)	(9,722		)
Balance at end of period	$	16,737		$	22,517

Additionally, we are subject to project management and installation-related contingencies as a result of our fixed-price material supply and installation service contracts, primarily in our Architectural Services segment and certain of our Architectural Framing Systems businesses, including those taken on with our acquisition of EFCO. We actively manage the risk of these exposures through contract negotiations, proactive project management and insurance coverages. The liability for these types of project-related contingencies was $42.1 million and $26.4 million as of March 2, 2019 and March 3, 2018, respectively.

Letters of credit

At March 2, 2019, we had $25.1 million of ongoing letters of credit, all of which have been issued under our revolving credit facility, as discussed in Note 8.

Purchase obligations

Purchase obligations for raw material commitments and capital expenditures totaled $132.2 million as of March 2, 2019.

Environmental liability

In fiscal 2008, we acquired one manufacturing facility which has certain historical environmental conditions. Remediation of these conditions is ongoing without significant disruption to our operations. The liability for these remediation activities was $1.2 million and $1.3 million at March 2, 2019 and March 3, 2018, respectively.

New Markets Tax Credit (NMTC) transactions

We have entered into four separate NMTC programs to support our operational expansion, including two transactions completed in the current fiscal year. Proceeds received from investors on these transactions are included within other non-current liabilities on our consolidated balance sheets. The NMTC arrangements are subject to 100 percent tax credit recapture for a period of seven years from the date of each respective transaction. Therefore, upon the termination of each arrangement, these proceeds will be recognized in earnings in exchange for the transfer of tax credits. The direct and incremental costs incurred in structuring these arrangements have been deferred and are included in other non-current assets on our consolidated balance sheets. These costs will be recognized in conjunction with the recognition of the related proceeds on each arrangement. During the construction phase, we are required to hold cash dedicated to fund each capital project which is classified as restricted cash on our consolidated balance sheets. Variable-interest entities, which have been included within our consolidated financial statements, have been created as a result of the structure of these transactions, as investors in the programs do not have a material interest in their underlying economics.

The table below provides a summary of our outstanding NMTC transactions (in millions):



Inception date	Termination date	Proceeds received		Deferred costs		Net benefit

Litigation

In November 2018, a purported class action lawsuit was filed claiming the Company and certain named executive officers made materially false and/or misleading statements and failed to disclose material adverse facts about the Company's business and operations during the period June 28, 2018 to September 17, 2018. In December 2018, a derivative lawsuit was filed, based on substantially similar allegations, against certain of our executive officers and directors claiming breach of fiduciary duty, waste of corporate assets and unjust enrichment. We intend to vigorously defend against both of these matters. Due to the preliminary nature of these matters, we are unable to estimate any potential loss at this time.

In addition to the foregoing, 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.

Shareholders' Equity

A class of 200,000 shares of junior preferred stock with a par value of $1.00 is authorized, but unissued.

Share Repurchases

During fiscal 2004, the Board of Directors authorized a share repurchase program, with subsequent increases in authorization, including an increase in authorization by 2,000,000 shares in fiscal 2019. We repurchased 1,257,983 shares under the program during fiscal 2019, for a total cost of $43.3 million. We repurchased 702,299 shares under the program, for a total cost of $33.7 million, in fiscal 2018, and 250,001 shares under the program, for a total cost of $10.8 million, in fiscal 2017. The Company has repurchased a total of 5,267,915 shares, at a total cost of $149.3 million, since the inception of this program. We have remaining authority to repurchase 1,982,085 shares under this program, which has no expiration date.

In addition to the shares repurchased under this repurchase plan, during fiscal 2019, 2018 and 2017, the Company also withheld $2.0 million, $3.0 million and $2.6 million, respectively, of Company stock from employees in order to satisfy stock-for-stock option exercises or tax obligations related to stock-based compensation, pursuant to terms of board and shareholder-approved compensation plans.

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.

Total stock-based compensation expense under all Plans included in the results of operations was $6.3 million for fiscal 2019, $6.2 million for fiscal 2018 and $6.0 million for 2017. 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 3, 2018	129,901		$	11.10
Awards exercised	(29,560	)	20.43
Outstanding and exercisable at March 2, 2019	100,341		$	8.34	2.5 Years	$	2,778,442

Cash proceeds from the exercise of stock options were $0.2 million, $0.8 million and $1.9 million for fiscal 2019, 2018 and 2017, 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 $0.6 million, $4.8 million and $6.0 million in fiscal 2019, 2018 and 2017, respectively.

Nonvested Share Awards and Units

The following table summarizes nonvested share activity for fiscal 2019:



	Number of Shares and Units		Weighted Average Grant Date Fair Value
March 3, 2018	266,180		$	49.22

Canceled	(19,442	)	48.93
March 2, 2019	286,613		$	47.00

At March 2, 2019, there was $6.7 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 2019 was $5.1 million.

Income tax payments, net of refunds, were $16.5 million, $25.7 million and $47.8 million in fiscal 2019, 2018 and 2017, respectively.

The following table provides a reconciliation of the statutory federal income tax rate to our consolidated effective tax rates:



	2019		2018		2017
Statutory federal income tax rate	21.0	%	32.7	%	35.0	%
Tax rate change revaluation	—		(3.7	)	—

Other, net	0.3		0.7		(0.9	)
Consolidated effective income tax rate	22.1	%	27.7	%	30.1	%

The estimated effective tax rate for fiscal 2019 declined 5.6 percentage points from fiscal 2018 primarily due to the reduced Federal rate under the U.S. Tax Cuts and Jobs Act ("the Act"), which was enacted in December 2017. Another factor was the impact of the favorable permanent items in relation to lower earnings before income taxes in fiscal 2019. The estimated effective tax rate for fiscal 2018 declined 2.4 percentage points from fiscal 2017 primarily due to the federal tax rate reduction under the Act, as well as the revalution of deferred taxes required by the tax rate reduction. Also in fiscal 2017, we recorded a net tax benefit of $1.9 million on a distribution from our Brazilian operation.

In fiscal 2019, we completed our analysis of the Act and made an accounting policy election to recognize the tax expense on future U.S. inclusions of foreign sourced earnings under the Global Intangible Low-Taxed Income (“GILTI”) provision, if any, as a current period expense when incurred. Upon finalizing our analysis, no significant adjustments were recorded.

Deferred tax assets and deferred tax liabilities at March 2, 2019 and March 3, 2018 were:



(In thousands)	2019			2018
Other accruals	$	13,530		$	3,428

Unearned income	4,557			2,628
Other	1,550			1,067
Deferred tax assets (liabilities)	$	3,118		$	(3,303	)

The Company has U.S. federal tax credits as well as state net operating loss carryforwards with a tax effect of $9.9 million. A valuation allowance of $8.5 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 2016, or state and local income tax examinations for years prior to fiscal 2013. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2015, 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 United States 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 the 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, $3.1 million, $2.4 million and $2.1 million for fiscal 2019, 2018 and 2017, respectively, would benefit the effective tax rate. Also included in the balance of unrecognized tax benefits for fiscal 2019, 2018 and 2017, are $2.0 million, $2.3 million and $2.0 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 2019, we accrued penalties and interest related to unrecognized tax benefits of $0.3 million. For fiscal 2018 and 2017, the accrual was $0.4 million and $0.4 million, respectively.

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

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.

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 and, in fiscal 2019, also includes $40.9 million of project-related charges on acquired contracts. 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.

Revenue Recognition

Revenue recognition

As outlined within the new accounting guidance, we elected several practical expedients in our transition to ASC 606:


•	We have made an accounting policy election to account for shipping and handling activities that occur after control of the related goods transfers to the customer as fulfillment activities, instead of assessing such activities as performance obligations.


•	We have made an accounting policy election to exclude from the transaction price all sales taxes related to revenue-producing transactions that are collected from the customer for a government authority.


•	We generally expense incremental costs of obtaining a contract when incurred because the amortization period would be less than one year. These costs primarily relate to sales commissions and are included in selling, general and administrative expenses.


•	We have not adjusted contract price for a significant financing component, as we expect the period between when our goods and services are transferred to the customer and when the customer pays for those goods and services to be less than a year.

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

Shipping and Handling

Shipping and handling

Amounts billed to a customer in a sales transaction related to shipping and handling are reported as revenue. Costs incurred by the Company for shipping and handling are reported as cost of sales.

Research and Development

Advertising

Advertising costs are expensed as incurred within selling, general and administrative expenses, and were $1.5 million in fiscal 2019, $1.4 million in fiscal 2018 and $1.1 million in fiscal 2017.
