Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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 three-month period ended June 2, 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 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 34 percent of our total revenue in the current period. 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 and are therefore 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 20 percent of our total revenue in the current period, 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 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 quarter ending June 2, 2018, the application of the new accounting guidance had the following impact on our consolidated financial statements:



In thousands	As reported		Balances without adoption of ASC 606

Net sales	$	336,531	$	327,251
Cost of sales	255,801		248,657
Gross profit	80,730		78,594
Selling, general and administrative expenses	58,735		58,386

Costs and earnings on contracts in excess of billings	39,365		15,265
Billings on contracts in excess of costs and earnings	24,381		24,124
Other current liabilities	74,269		73,297
Retained earnings	386,518		384,876

The changes above 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.

We also adopted ASU 2016-15, Statement of Cash Flows, and ASU 2016-18, Restricted Cash, this quarter. 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.

Finally, we elected to early adopt ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, in the current quarter. 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 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 year 2020. 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 we do not currently expect this guidance to have a significant impact on our consolidated results of operations. In January 2018, the FASB issued a proposed accounting standard update to the guidance that would allow an entity the option to adopt the guidance on a modified retrospective basis. Under the modified retrospective approach, 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. We are monitoring the status of the proposal. We have started the process of gathering and analyzing our lease contracts and are in the process of evaluating changes to our business processes, systems and controls needed to support recognition and disclosure under this new standard.

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.

The following table disaggregates total revenue by timing of recognition (see Note 13 for disclosure of revenue by segment):



In thousands
Recognized at shipment	$	156,867
Recognized over time	179,664
Total	$	336,531

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 where amounts are released.

Less: allowance for doubtful accounts	(1,389		)	(1,530		)
Net receivables	$	185,543		$	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 our businesses which 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.

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. The increase in contract liabilities was due to timing of project activity within our businesses that operate under long-term contracts.

In the first quarter of fiscal 2019, we recognized revenue of $9.1 million related to contract liabilities at March 4, 2018 and revenue of $2.3 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 June 2, 2018, the transaction price associated with unsatisfied performance obligations is approximately $714.4 million. The performance obligations are expected to be satisfied, and the corresponding revenue to be recognized, over the following estimated time periods:

Cash proceeds from the exercise of stock options were $0.2 million and $0.8 million for the three months ended June 2, 2018 and June 3, 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 during the three months ended June 2, 2018 and $4.8 million during the prior-year period.

Nonvested shares and share units

Nonvested share activity for the current three-month period is summarized as follows:

Marketable Securities

Marketable securities

We hold the following available-for-sale marketable securities, made up of municipal and corporate bonds:



In thousands	Amortized Cost	Gross Unrealized Gains	Gross Unrealized Losses		Estimated Fair Value

March 3, 2018	9,183	8	(138	)	9,053

We have a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism), which holds these municipal and corporate 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 municipal bonds at June 2, 2018, 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 financial assets or liabilities.

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

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 June 2, 2018, we held foreign exchange forward contracts with a U.S. dollar notional value of $23.4 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 $0.2 million as of June 2, 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.

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 $192 million in cash. The acquisition was funded through our committed revolving credit facility, with $7.5 million of the purchase price payable in equal installments over the subsequent three years. 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. Those results include $65.3 million of sales and break-even operating income in the current period.

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 as to projections of future operating performance, the appropriate discount rate to apply, long-term growth rates, etc. (i.e. - 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 that follows is based on these estimated fair values of assets acquired and liabilities assumed, which was finalized in the current quarter:

Net working capital	$	1,422

Debt	3 Months Ended
Debt	Jun. 02, 2018
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 $193.0 million, as of June 2, 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 June 2, 2018, we were in compliance with both financial covenants. Additionally, at June 2, 2018, we had a total of $23.5 million of ongoing letters of credit related to industrial revenue bonds and construction contracts that expire in fiscal 2019 and reduce availability of funds under our committed credit facility. At June 2, 2018, our debt 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. The fair value of the industrial revenue bonds approximated carrying value at June 2, 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 revolving demand credit facilities totaling $12.0 million Canadian dollars. As of June 2, 2018, $0.7 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 $1.8 million and $0.5 million for the three months ended June 2, 2018 and June 3, 2017, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes 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 2011. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2014, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions. The total liability for unrecognized tax benefits at June 2, 2018 and March 3, 2018 was approximately $5.3 million and $5.1 million, respectively. Penalties and interest related to unrecognized tax benefits are recorded in income tax expense. The total liability for unrecognized tax benefits is expected to decrease by approximately $0.6 million during the next 12 months due to lapsing of statutes. The Tax Cuts and Jobs Act (the Act) was enacted in December 2017. Among other provisions, the Act created a new tax on certain foreign sourced earnings under the Global Intangible Low-Taxed Income (“GILTI”) provision. Companies are allowed to make an accounting policy election of either treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred or factoring such amounts into the measurement of deferred taxes. We have completed our analysis of the GILTI provisions and are making an accounting policy election to recognize the tax expense on future U.S. inclusions of GILTI income, if any, as a current period expense when incurred.

Commitments and Contingent Liabilities

Operating lease commitments. As of June 2, 2018, 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:

Bond commitments. 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 June 2, 2018, $238.7 million of our backlog was bonded by performance bonds with a face value of $535.0 million. Performance bonds do not have stated expiration dates, as we are generally released from the bonds upon completion of the contract. We have never been required to make any payments related to these performance bonds with respect to any of our 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 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:

Purchase obligations. Purchase obligations for raw material commitments and capital expenditures totaled $186.4 million as of June 2, 2018.

Litigation. We are a party to various legal proceedings incidental to our normal operating activities. In particular, like others in the construction supply and services industry, our businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. We are also 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 our results of operations, cash flows or financial condition.
