Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation The consolidated financial statements of Apogee Enterprises, Inc. (we, us, our or the Company) have been prepared in accordance with accounting principles generally accepted in the United States. The information included in this Form 10-Q should be read in conjunction with the Company’s Form 10-K for the year ended March 3, 2018 . We use the same accounting policies in preparing quarterly and annual financial statements. All adjustments necessary for a fair presentation of quarterly operating results are reflected herein and are of a normal, recurring nature. The results of operations for the nine -month period ended December 1, 2018 are not necessarily indicative of the results to be expected for the full year. Certain prior-year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the consolidated results of operations. Significant accounting policies update Our significant accounting policies are included in Note 1 "Summary of Significant Accounting Policies and Related Data" of our Annual Report on Form 10-K for the year ended March 3, 2018. 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. In the current year-to-date period, approximately 46 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 33 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 proport ion 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 h ave one business, making up approximately 21 percent of our to tal 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 p eriod. We believe this over-time output method of recognizing revenue reasonably depicts the fulfillment of our performance obligations under our contracts. Previo usly, 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. Adoption of new accounting standards We adopted the new guidance in ASC 606 using the modified retrospective transition method applied to those contracts which were not complete as of March 4, 2018. 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 nine -month periods ending December 1, 2018 , the application of the new accounting guidance had the following impact on our consolidated financial statements: Three Months Ended December 1, 2018 Nine Months Ended December 1, 2018 In thousands As reported Without adoption of ASC 606 As reported Without adoption of ASC 606 Net sales $ 357,718 $ 355,765 $ 1,056,382 $ 1,042,600 Cost of sales 273,628 272,087 807,096 796,802 Gross profit 84,090 83,678 249,286 245,798 Selling, general and administrative expenses 52,682 52,692 167,224 166,560 Operating income $ 31,408 $ 30,986 $ 82,062 $ 79,238 Income tax expense $ 6,730 $ 6,627 $ 18,030 $ 17,355 Net earnings $ 21,891 $ 21,572 $ 57,778 $ 55,628 December 1, 2018 As reported Without adoption of ASC 606 Inventories $ 79,847 $ 89,250 Costs and earnings on contracts in excess of billings 60,140 30,756 Billings on contracts in excess of costs and earnings 26,961 25,923 Other current liabilities 59,230 57,802 Retained earnings 400,289 398,139 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 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. 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. The new standard is effective for fiscal years beginning after December 15, 2018, our fiscal year 2020. In July 2018, the FASB issued an additional update which allows an entity the option to adopt the guidance on a modified retrospective basis. Under the modified retrospective approach, which we plan to adopt in implementing the new guidance, an entity would recognize a cumulative effect adjustment of initially applying the guidance to the opening balance of retained earnings in the period of adoption. Prior period amounts will not be adjusted. We are in the process of analyzing our lease arrangements and evaluating our initial right-to-use asset and lease liability balances, including determining estimates and assumptions used in the calculation of the lease asset and liability. We are also in the process of determining modifications to our business processes, accounting policies and systems and controls that are needed to support measurement, recognition and disclosure under this new standard. We expect that the adoption of this standard will result in reflecting a material right-of-use asset and lease liability on our consolidated balance sheet. In adopting the new standard, we plan to elect the package of practical expedients, as well as the practical expedient to not separate nonlease components from lease components. We plan to adopt the new guidance following the modified retrospective application approach. We do not expect this standard to have a significant impact on our consolidated results of operations or consolidated statements of cash flows. Subsequent events We have evaluated subsequent events for potential recognition and disclosure through the date of this filing. Subsequent to the end of the quarter, we purchased 504,004 shares of stock under our authorized share repurchase program, at a total cost of $14.9 million .

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 where amounts are released.

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 thousands December 1, 2018 March 3, 2018 Contract assets $ 93,316 $ 30,508 Contract liabilities 30,447 20,120 The increase in contract assets was 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. In the first nine months of fiscal 2019, we recognized revenue of $10.4 million related to contract liabilities at March 4, 2018, and revenue of $3.8 million related to performance obligations satisfied in previous periods due to changes in contract estimates. For the third quarter of fiscal 2019, we did not recognize any revenue related to contract liabilities at March 4, 2018, and recognized revenue of $1.5 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 December 1, 2018 , the transaction price associated with unsatisfied performance obligations was approximately $706.3 million . The performance obligations are expected to be satisfied, and the corresponding revenue to be recognized, over the following estimated time periods: In thousands December 1, 2018 Within one year $ 421,778 Within two years 236,037 Beyond 48,493 Total $ 706,308

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 municipal bonds at December 1, 2018 , by contractual maturity, are shown below.

Short- and long-term securities Mutual funds were measured at fair value based on quoted prices for identical assets in active markets. Municipal and corporate 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. 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. As of December 1, 2018 , we held foreign exchange forward contracts with a U.S. dollar notional value of $16.0 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 liability of $0.4 million as of December 1, 2018 . 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 Disclosure [Abstract]
Debt	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 $211.5 million , as of December 1, 2018 , and $195.0 million , 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. At December 1, 2018 , we were in compliance with both financial covenants. Additionally, at December 1, 2018 , we had a total of $25.1 million of ongoing letters of credit related to industrial revenue bonds and construction contracts that expire in fiscal 2020 and reduce availability of funds under our committed credit facility. At December 1, 2018 , our debt 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. The fair value of the industrial revenue bonds approximated carrying value at December 1, 2018 , due to the variable interest rates on these instruments. All debt would be classified as Level 2 within the fair value hierarchy described in Note 5. We also maintain two Canadian demand credit facilities totaling $ 12.0 million Canadian dollars. As of December 1, 2018 , $0.4 million was outstanding under these facilities, and no borrowings were outstanding as of March 3, 2018 . Borrowings under these facilities are made available at the sole discretion of the lenders and are payable on demand. The Company classifies any outstanding balances under these demand facilities as long-term debt, as outstanding amounts can be refinanced through our committed revolving credit facility. Interest payments were $7.2 million and $3.6 million for the nine months ended December 1, 2018 and December 2, 2017 , respectively.

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 Remainder of Fiscal 2019 Fiscal 2020 Fiscal 2021 Fiscal 2022 Fiscal 2023 Thereafter Total Total minimum payments $ 3,890 $ 14,759 $ 11,522 $ 9,353 $ 8,459 $ 23,308 $ 71,291 Bond commitments and installation project contingencies In the ordinary course of business, predominantly in our 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 December 1, 2018 , $224.0 million of our backlog was bonded by these types of bonds with a face value of $478.8 million . These bonds do not have stated expiration dates, as we are generally 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. Additionally, we also 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. Warranties We reserve estimated exposures on known claims, as well as on a portion of anticipated claims, for product warranty and rework cost, 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: Nine Months Ended In thousands December 1, 2018 December 2, 2017 Balance at beginning of period $ 22,517 $ 21,933 Additional accruals 3,437 3,443 Claims paid (8,398 ) (8,254 ) Acquired reserves — 5,571 Balance at end of period $ 17,556 $ 22,693 Letters of credit At December 1, 2018 , we had $25.1 million of ongoing letters of credit, all of which have been issued under our committed revolving credit facility, as discussed in Note 7. Purchase obligations Purchase obligations for raw material commitments and capital expenditures totaled $163.2 million as of December 1, 2018 . New Markets Tax Credit transactions In September 2018, we entered into a transaction with SunTrust Community Capital (STCC) under a qualified New Markets Tax Credit (NMTC) program related to an investment in plant and equipment within our Architectural Framing Systems segment. STCC contributed $3.2 million to this project, which is included in other non-current liabilities on our consolidated balance sheets. We have completed two NMTC transactions this fiscal year. Under the terms of these arrangements, we are required to hold cash dedicated to fund the related capital projects which is classified as restricted cash on our consolidated balance sheets. Since fiscal 2014, we have entered into four separate NMTC programs to support our operational expansion. 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 at the end of the seven-year period, proceeds received from investors will be recognized in earnings in exchange for the transfer of tax credits. Direct and incremental costs incurred in structuring these arrangements have been deferred and will be recognized in conjunction with the recognition of the related profits. Variable-interest entities have been created as a result of the transaction structure, which have been included within our consolidated financial statements as investors in the program do not have a material interest in the underlying economics of the respective projects. 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 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 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 is routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is also subject to litigation arising out of areas such as employment practices, workers compensation and general liability matters. Although it is very difficult to accurately predict the outcome of any such proceedings, facts currently available indicate that no matters will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.
