Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Related Data	Summary of Significant Accounting Policies and Related Data Basis of Consolidation. The consolidated financial statements include the balances of Apogee Enterprises, Inc. and its subsidiaries (Apogee, the Company or we) after elimination of intercompany balances and transactions. We consolidate variable interest entities where it has been determined that the Company is the primary beneficiary of those entities' operations. Fiscal Year. Our fiscal year ends on the Saturday closest to the last day of February, or as determined by the Board of Directors. Fiscal 2016 , 2015 and 2014 each consisted of 52 weeks. Our Brazilian subsidiary follows a calendar year-end and is consolidated on a two -month lag. Accounting Estimates. The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates. Cash Equivalents. Highly liquid investments with an original maturity of three months or less are included in cash equivalents and are stated at cost, which approximates fair value. 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. Our manufacturing operations recognize costs of sales using standard costs with full overhead absorption, which generally approximates actual cost. Property, Plant and Equipment. Property, plant and equipment are 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 property 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. Depreciation is computed on a straight-line basis, based on the following estimated useful lives: Years Buildings and improvements 15 to 25 Machinery and equipment 3 to 15 Office equipment and furniture 3 to 10 Goodwill and Other 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. Step one of the process compares 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. We have seven business units which each represent a reporting unit for the goodwill impairment analysis. Based on our analysis, the estimated fair value of each reporting unit exceeded its carrying value and, therefore, goodwill impairment was not indicated. In all periods presented, we have followed a consistent discounted cash flow methodology in order to evaluate goodwill for impairment. Intangible assets with defined useful lives are amortized based on estimated useful lives ranging from three to 20 years. The remaining useful lives of all intangible assets are reviewed annually, and we have determined that the remaining lives were appropriate. Long-Lived Assets. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If impairment indicators are present and the estimated undiscounted future cash flows are less than the carrying value of the assets, the carrying values would be reduced to the estimated fair value. Fair value is measured using discounted cash flows or independent opinions of value, as appropriate. Self-Insurance. We obtain commercial insurance for potential losses for general liability, employment practices, workers' compensation, automobile liability, architect's and engineer's errors and omissions risk, product rework and other miscellaneous coverages. A substantial portion of this risk is retained on a self-insured basis through our wholly-owned insurance subsidiary. We establish a reserve for estimated ultimate losses on reported claims and those incurred but not yet reported utilizing actuarial projections. Reserves are classified within accrued or long-term self-insurance reserves based on expectations of when the estimated loss will be paid. Additionally, we maintain a self-insurance reserve for health insurance programs offered to eligible employees, included within accrued self-insurance reserves. The reserve includes an estimate for losses on reported claims as well as for amounts incurred but not yet reported, based on historical trends. Warranty. We are subject to claims associated with our products and services, principally as a result of disputes with our customers involving the performance or aesthetics of our architectural products and services. We reserve estimated exposures on known claims, as well as on a portion of anticipated claims for product warranty and rework costs based on historical product liability claims as a ratio of sales. Our warranty reserves are included in other current and non-current liabilities based on the estimated timing of dispute resolution. Environmental Liability. We recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated based upon estimates by specialists and applicable law. Such estimates are based primarily upon the estimated cost of investigation and remediation required, and the likelihood that, where applicable, other potentially responsible parties will not be able to fulfill their commitments at the sites where the Company may be jointly and severally liable. The reserve for environmental liabilities is included in other current and non-current liabilities in the consolidated balance sheets. Foreign Currency. The financial statements of subsidiaries located outside of the U.S. are measured in their functional currency, which is local currency. 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. Revenue Recognition. We recognize revenue when title has transferred, except within our Architectural Services segment, which enters into fixed-price installation contracts. These contracts are typically performed over a 12 - to 18 -month timeframe, and we record revenue for these contracts on a percentage-of-completion basis as we are able to reasonably estimate total contract revenue and total contract costs. We compare the total costs incurred to date to the total estimated costs for the contract, and record that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. We believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of accuracy in measuring revenue throughout the contract period. Provisions are established for estimated losses, if any, on uncompleted contracts in the period in which such losses are determined. Amounts representing contract change orders, claims or other items are included in contract revenue only upon customer approval. Approximately 25 percent of our consolidated net sales in fiscal 2016 and 2015 , and 26 percent in 2014 , were recorded on a percentage-of-completion basis. Revenue excludes sales taxes as the Company considers itself a pass-through conduit for collecting and remitting sales taxes. Pricing and Sales Incentives. The Company records estimated reductions to revenue for customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives at the later of the date revenue is recognized or the incentive is offered. Sales incentives given to customers are recorded as a reduction to net sales unless (1) the Company receives an identifiable benefit for goods or services in exchange for the consideration, and (2) the Company can reasonably estimate the fair value of the benefit received. Shipping and Handling. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as revenue. Costs incurred by the Company for shipping and handling are reported as cost of sales. Research and Development. Research and development costs are expensed as incurred within selling, general and administrative expenses, and were $8.0 million , $6.5 million and $7.8 million for fiscal 2016 , 2015 and 2014 , respectively. Of these amounts, $2.4 million , $2.4 million and $2.1 million , respectively, were focused primarily upon design of custom window and curtainwall systems in accordance with customer specifications and are included in cost of sales. Advertising. Advertising costs are expensed as incurred and were $1.2 million in fiscal 2016 , $1.1 million in fiscal 2015 , and $1.2 million in fiscal 2014 , and they are included in selling, general and administrative expenses. 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 and determined that there were no subsequent events that required recognition or disclosure in the consolidated financial statements. New Accounting Standards . In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes and statutory tax withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016. We are currently evaluating the impact this standard will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , which provides for a comprehensive change to lease accounting. The new standard requires that a lessee recognize a lease obligation liability and a right to use asset for virtually all leases of property, plant and equipment, subsequently amortized over the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, with a modified retrospective transition. We are currently evaluating the impact this standard will have on our consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes , which requires all deferred tax assets and liabilities, along with any related valuation allowance, to be classified as noncurrent on the balance sheet. The new standard is effective for fiscal years beginning after December 15, 2016, and may be applied prospectively or retrospectively, with early adoption permitted. We plan to adopt this standard in the first quarter of our fiscal 2017 and do not expect this to have a significant impact on our consolidated balance sheet. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Under the new standard, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2017, Apogee's fiscal 2019. We are currently evaluating the impact this standard will have on our consolidated financial statements.

The reinsurance carrier requires Prism to maintain fixed-maturity investments, which are generally high-quality municipal bonds, for the purpose of providing collateral for Prism's obligations under the reinsurance agreement. We test for other-than-temporary losses on a quarterly basis and whenever events or changes in circumstances indicate that the carrying amount of an investment may not be recoverable. We consider the unrealized losses indicated above to be temporary in nature. We intend to hold our investments until the full principal amount can be recovered, and we have the ability to do so based on other sources of liquidity.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	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 $5.4 million in fiscal 2016 , $4.7 million in fiscal 2015 and $4.2 million in fiscal 2014 . Deferred Compensation Plan The Company maintains a plan that allows participants to defer compensation. The deferred compensation liability was $5.0 million and $4.2 million at February 27, 2016 and February 28, 2015 , respectively. The Company has investments in corporate-owned life insurance policies (COLI) of $4.8 million and mutual funds of $0.3 million with the intention of utilizing them as a long-term funding source 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 2016 , 2015 and 2014 was $3.6 million , $4.3 million and $3.7 million , respectively. Pension Plan The Company sponsors the Tubelite Inc. Hourly Employees' Pension Plan (Tubelite Plan), a defined-benefit pension plan that was frozen to new entrants in fiscal 2004, with no additional benefits accruing to plan participants after such time. Officers' Supplemental Executive Retirement Plan (SERP) The Company sponsors an unfunded SERP for the benefit of certain executives, a defined-benefit pension plan that was frozen to new entrants in fiscal 2009, with no additional benefits accruing to plan participants after such time. Obligations and Funded Status of Defined-Benefit Pension Plans The following tables present reconciliations of the benefit obligation of the defined-benefit pension plans and the funded status of the defined-benefit pension plans. The Tubelite plan uses a measurement date as of the calendar month-end closest to our fiscal year-end, while the SERP uses a measurement date aligned with our fiscal year-end.

The estimated net actuarial loss for the defined-benefit pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost for fiscal 2017 is $0.2 million , net of tax benefit. Additional Information Assumptions Benefit Obligation Weighted-Average Assumptions 2016 2015 2014 Discount rate 3.85 % 3.60 % 4.00 % Net Periodic Benefit Expense Weighted-Average Assumptions 2016 2015 2014 Discount rate 3.60 % 4.00 % 3.75 % Expected long-term rate of return on assets 2.00 % 4.50 % 4.50 % 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 2017 . Expected return on assets. To develop the expected long-term rate of return on assets, we considered historical long-term rates of return achieved by the plan investments, the plan's investment strategy, and current and projected market conditions. In accordance with its policy, during fiscal 2016, the assets of the Tubelite plan were invested in a short-term bond fund and carried at fair value based on prices from recent trades of similar securities, which would be classified as Level 2 in the valuation hierarchy. Prior to this strategy change, the assets were invested in a long-term bond fund. We do not maintain assets intended for the future use of the SERP. Contributions Pension contributions to the plans for each of fiscal 2016 and 2015 totaled $0.9 million , which equaled or exceeded the minimum funding requirement. Estimated Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid by the plans: (In thousands) Fiscal 2017 $ 1,017 Fiscal 2018 1,004 Fiscal 2019 1,031 Fiscal 2020 1,016 Fiscal 2021 1,001 Fiscal 2022-2026 4,676 Employee Stock Purchase Plan The Company also sponsors an employee stock purchase plan into which employees may contribute up to $500 per week on an after-tax basis. The Company contributes a match of 15 percent of the employee contribution. Contributions and matching funds are used to purchase shares of Company stock on the open market. The Company match to this plan was $0.1 million in each of fiscal 2016 , 2015 and 2014 .

At February 27, 2016 , we had one sale and leaseback agreement for equipment that provides an option to purchase the equipment at projected future fair market value upon expiration of the lease in 2021 . The lease is classified as an operating lease in accordance with applicable financial accounting standards. The Company has a deferred gain of $2.3 million under the sale and leaseback transaction, which is included in the balance sheet as other current and non-current liabilities. The average annual lease payment over the remaining life of the lease is $1.0 million . Bond commitments. In the ordinary course of business, predominantly in the Company’s Architectural Services segment, the Company is required to provide surety or performance bonds that commit payments to its customers for any non-performance. At February 27, 2016 , $134.5 million of the Company’s backlog was bonded by performance bonds with a face value of $328.6 million . Performance bonds do not have stated expiration dates, as the Company is released from the bonds upon completion of the contract. The Company has never been required to make any payments related to these performance-based bonds with respect to any of its current portfolio of businesses. Warranties. We accrue for warranty and claim costs as a percentage of sales based on historical trends and for specific sales credits as they become known and estimable. Actual warranty and 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, shifts in product mix and any significant changes in sales volume. A warranty rollforward is provided below: (In thousands) 2016 2015 Balance at beginning of period $ 11,275 $ 11,978 Additional accruals 8,214 6,482 Claims paid (3,149 ) (7,185 ) Balance at end of period $ 16,340 $ 11,275 Letters of credit. At February 27, 2016 , we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The total value of letters of credit under which we were obligated as of February 27, 2016 was approximately $23.5 million , all of which have been issued under our credit facility. Our total availability under our $125.0 million credit facility is reduced by borrowings under the credit facility and also by letters of credit issued under the credit facility. Purchase obligations. Purchase obligations for raw material commitments and capital expenditures totaled $245.0 million as of February 27, 2016 . Environmental liability . In fiscal 2008, we acquired one manufacturing facility which has certain historical environmental conditions. We are working to remediate these conditions, which are being conducted without significant disruption to our operations. Our liability for these remediation activities was $1.6 million and $1.8 million at February 27, 2016 and February 28, 2015 , respectively. New Markets Tax Credit transaction. In fiscal 2014, we entered into a transaction with JP Morgan Chase (JPM) related to an investment in plant and equipment within the Architectural Glass segment (the Project) whereby we received $7.8 million of cash from a qualified New Markets Tax Credit transaction (NMTC). The NMTC is intended to induce investment in underserved and impoverished areas of the U.S. In exchange for substantially all of the benefits derived from the tax credits, JPM contributed $10.7 million into the Project. JPM does not have a material interest in the underlying economics of the Project. As a result of the transaction structure, the entities created under this transaction were determined to be variable-interest entities and have been consolidated. Based on our contractual obligation to deliver tax benefits to JPM, we have included the value of JPM’s contribution in other non-current liabilities within our consolidated balance sheets. The NMTC is subject to 100 percent recapture for a period of seven years. Proceeds received in exchange for the transfer of the tax credits are expected to be recognized as earnings in fiscal 2021, if the expected tax benefits are delivered without risk of recapture to JPM and our performance obligation is relieved. Direct and incremental costs incurred in structuring the arrangement have been deferred and will be recognized in proportion to the recognition of the related profits. These costs amounted to $3.3 million and are included in other non-current assets on our consolidated balance sheet. Litigation. The Company is a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company’s construction supply and services businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is subject to litigation arising out of general liability, employment practices, workers' compensation and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.

The following table provides a reconciliation of the statutory federal income tax rate to our consolidated effective tax rates: 2016 2015 2014 Federal income tax expense at statutory rate 35.0% 35.0% 35.0% Manufacturing deduction (3.4) (2.3) (3.5) State and local income taxes, net of federal tax benefit 1.6 1.2 0.9 Tax credits - research & development (0.8) (1.1) (1.6) Tax credits - 48C — (9.9) — Nondeductible acquisition costs — — 0.3 Tax reserve adjustments - statute expirations and benefits recognized — (0.2) (2.2) Change in valuation allowance — 0.1 0.4 Other, net 0.5 (0.5) 0.3 Income tax expense 32.9% 22.3% 29.6% In fiscal 2015, the Company recognized approximately $6.4 million of tax benefit from an energy-efficient investment credit under Section 48C of the U.S. Internal Revenue Code, upon successful start-up and commercial production of coatings on our new architectural glass coater. The tax credit was awarded in 2011 by the U.S. Internal Revenue Service (IRS) in cooperation with the Department of Energy as part of the American Reinvestment and Recovery Act to incent energy-efficient investments throughout the U.S. In fiscal 2016 , 2015 and 2014 , tax benefits associated with stock-based incentive plans were $3.9 million , $3.3 million and $2.6 million , respectively. These benefits impacted additional paid-in capital directly and were not reflected in the determination of income tax expense or benefit. Deferred tax assets and deferred tax liabilities at February 27, 2016 and February 28, 2015 are as follows: 2016 2015 (In thousands) Current Noncurrent Current Noncurrent Accounts receivable $ 825 $ — $ 1,022 $ — Other accruals 2,968 1,281 2,872 1,212 Deferred compensation 554 12,594 419 11,250 Goodwill and other intangibles 18 (7,615 ) 21 (7,994 ) Depreciation — (17,354 ) (853 ) (20,544 ) Liability for unrecognized tax benefits — 2,797 — 2,784 Net operating losses — 2,945 — 3,084 Valuation allowance on net operating losses (2,194 ) (306 ) (2,149 ) (442 ) Other (351 ) 686 27 (2 ) Deferred tax assets (liabilities) $ 1,820 $ (4,972 ) $ 1,359 $ (10,652 ) The Company has net operating loss carryforwards in certain U.S. state jurisdictions with a tax effect of $3.5 million . A valuation allowance of $2.5 million has been established for these net operating loss carryforwards due to the uncertainty of our ability to use 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 2013, or state and local income tax examinations for years prior to fiscal 2009. The Company is not currently under U.S. federal examination for years subsequent to fiscal 2012, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions. The Company considers the earnings of its non-U.S. subsidiaries to be indefinitely invested outside of the U.S. on the basis of estimates that future domestic cash generation will be sufficient to meet future domestic cash needs and specific plans for reinvestment of those subsidiary earnings. Should the Company decide to repatriate the foreign earnings, it would need to adjust the income tax provision in the period during which it was determined that the earnings will no longer be indefinitely invested outside the U.S. If we were to prevail on all unrecognized tax benefits recorded, $2.7 million for fiscal 2016 and $2.6 million for each of fiscal 2015 and fiscal 2014 would benefit the effective tax rate. Also included in the balance of unrecognized tax benefits for fiscal 2016 , 2015 and 2014 , are $1.8 million , $1.9 million and $1.8 million , respectively, of tax benefits that, if recognized, would result in adjustments to deferred taxes. Penalties and interest related to unrecognized tax benefits are recorded in income tax expense. During fiscal 2016, our accrual of $0.5 million for penalties and interest related to unrecognized tax benefits was consistent with the prior year. During fiscal 2015 and 2014, respectively, we reduced our accrual for penalties and interest by $0.3 million and $0.5 million , resulting in reserve balances of $0.5 million and $0.8 million at the end of fiscal 2015 and fiscal 2014 , respectively. The following table provides a reconciliation of the total amounts of gross unrecognized tax benefits: (In thousands) 2016 2015 2014 Gross unrecognized tax benefits at beginning of year $ 4,491 $ 4,431 $ 5,516 Gross increases in tax positions for prior years 60 261 44 Gross decreases in tax positions for prior years (158 ) (276 ) (616 ) Gross increases based on tax positions related to the current year 526 508 326 Gross decreases based on tax positions related to the current year (33 ) (21 ) (40 ) Settlements — (93 ) (84 ) Statute of limitations expiration (374 ) (319 ) (809 ) Unrecognized tax benefits acquired — — 94 Gross unrecognized tax benefits at end of year $ 4,512 $ 4,491 $ 4,431 The total liability for unrecognized tax benefits is expected to decrease by approximately $0.9 million during fiscal 2017 due to audit settlements and lapsing of statutes.

Segment Reporting [Abstract]
Business Segment Data	Business Segment Data We have four reporting segments: • The Architectural Glass segment fabricates coated, high-performance glass used in customized window and wall systems comprising the outside skin of commercial, institutional and high-end multi-family residential buildings. • The Architectural Services segment designs, engineers, fabricates and installs the walls of glass, windows and other curtainwall products making up the outside skin of commercial and institutional buildings. • The Architectural Framing Systems segment designs, engineers, fabricates and finishes the aluminum frames used in customized aluminum and glass window, curtainwall, storefront and entrance systems comprising the outside skin and entrances of commercial, institutional and high-end multi-family residential buildings. We have aggregated four operating segments into this reporting segment based on their similar products, customers, distribution methods, production processes and economic characteristics. • The Large-Scale Optical Technologies (LSO) segment manufactures value-added glass and acrylic products for the custom picture framing and fine art markets.

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

Summary of Significant Accoun27

Summary of Significant Accounting Policies and Related Data (Policies)	12 Months Ended
	Feb. 27, 2016
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation. The consolidated financial statements include the balances of Apogee Enterprises, Inc. and its subsidiaries (Apogee, the Company or we) after elimination of intercompany balances and transactions. We consolidate variable interest entities where it has been determined that the Company is the primary beneficiary of those entities' operations.
Fiscal Year	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 2016 , 2015 and 2014 each consisted of 52 weeks. Our Brazilian subsidiary follows a calendar year-end and is consolidated on a two -month lag.
Accounting Estimates	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	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
Inventories	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. Our manufacturing operations recognize costs of sales using standard costs with full overhead absorption, which generally approximates actual cost.
Property, Plant and Equipment	Property, Plant and Equipment. Property, plant and equipment are 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 property 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. Depreciation is computed on a straight-line basis, based on the following estimated useful lives: Years Buildings and improvements 15 to 25 Machinery and equipment 3 to 15 Office equipment and furniture 3 to 10
Goodwill and Other Intangible Assets	Goodwill and Other 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. Step one of the process compares 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. We have seven business units which each represent a reporting unit for the goodwill impairment analysis. Based on our analysis, the estimated fair value of each reporting unit exceeded its carrying value and, therefore, goodwill impairment was not indicated. In all periods presented, we have followed a consistent discounted cash flow methodology in order to evaluate goodwill for impairment. Intangible assets with defined useful lives are amortized based on estimated useful lives ranging from three to 20 years. The remaining useful lives of all intangible assets are reviewed annually, and we have determined that the remaining lives were appropriate.
Long-Lived Assets	Long-Lived Assets. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If impairment indicators are present and the estimated undiscounted future cash flows are less than the carrying value of the assets, the carrying values would be reduced to the estimated fair value. Fair value is measured using discounted cash flows or independent opinions of value, as appropriate.
Self-Insurance	Self-Insurance. We obtain commercial insurance for potential losses for general liability, employment practices, workers' compensation, automobile liability, architect's and engineer's errors and omissions risk, product rework and other miscellaneous coverages. A substantial portion of this risk is retained on a self-insured basis through our wholly-owned insurance subsidiary. We establish a reserve for estimated ultimate losses on reported claims and those incurred but not yet reported utilizing actuarial projections. Reserves are classified within accrued or long-term self-insurance reserves based on expectations of when the estimated loss will be paid. Additionally, we maintain a self-insurance reserve for health insurance programs offered to eligible employees, included within accrued self-insurance reserves. The reserve includes an estimate for losses on reported claims as well as for amounts incurred but not yet reported, based on historical trends.
Warranty	Warranty. We are subject to claims associated with our products and services, principally as a result of disputes with our customers involving the performance or aesthetics of our architectural products and services. We reserve estimated exposures on known claims, as well as on a portion of anticipated claims for product warranty and rework costs based on historical product liability claims as a ratio of sales. Our warranty reserves are included in other current and non-current liabilities based on the estimated timing of dispute resolution.
Environmental Liability	Environmental Liability. We recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated based upon estimates by specialists and applicable law. Such estimates are based primarily upon the estimated cost of investigation and remediation required, and the likelihood that, where applicable, other potentially responsible parties will not be able to fulfill their commitments at the sites where the Company may be jointly and severally liable. The reserve for environmental liabilities is included in other current and non-current liabilities in the consolidated balance sheets.
Foreign Currency	Foreign Currency. The financial statements of subsidiaries located outside of the U.S. are measured in their functional currency, which is local currency. 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.
Revenue Recognition	Revenue Recognition. We recognize revenue when title has transferred, except within our Architectural Services segment, which enters into fixed-price installation contracts. These contracts are typically performed over a 12 - to 18 -month timeframe, and we record revenue for these contracts on a percentage-of-completion basis as we are able to reasonably estimate total contract revenue and total contract costs. We compare the total costs incurred to date to the total estimated costs for the contract, and record that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. We believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of accuracy in measuring revenue throughout the contract period. Provisions are established for estimated losses, if any, on uncompleted contracts in the period in which such losses are determined. Amounts representing contract change orders, claims or other items are included in contract revenue only upon customer approval. Approximately 25 percent of our consolidated net sales in fiscal 2016 and 2015 , and 26 percent in 2014 , were recorded on a percentage-of-completion basis. Revenue excludes sales taxes as the Company considers itself a pass-through conduit for collecting and remitting sales taxes.
Pricing and Sales Incentives	Pricing and Sales Incentives. The Company records estimated reductions to revenue for customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives at the later of the date revenue is recognized or the incentive is offered. Sales incentives given to customers are recorded as a reduction to net sales unless (1) the Company receives an identifiable benefit for goods or services in exchange for the consideration, and (2) the Company can reasonably estimate the fair value of the benefit received.
Shipping and Handling	Shipping and Handling. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as revenue. Costs incurred by the Company for shipping and handling are reported as cost of sales.
Research and Development	Research and Development. Research and development costs are expensed as incurred within selling, general and administrative expenses, and were $8.0 million , $6.5 million and $7.8 million for fiscal 2016 , 2015 and 2014 , respectively. Of these amounts, $2.4 million , $2.4 million and $2.1 million , respectively, were focused primarily upon design of custom window and curtainwall systems in accordance with customer specifications and are included in cost of sales.
Advertising	Advertising. Advertising costs are expensed as incurred and were $1.2 million in fiscal 2016 , $1.1 million in fiscal 2015 , and $1.2 million in fiscal 2014 , and they are included in selling, general and administrative expenses.
Income Taxes	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	Subsequent Events. We have evaluated subsequent events for potential recognition and disclosure through the date of this filing and determined that there were no subsequent events that required recognition or disclosure in the consolidated financial statements.
New Accounting Standards	New Accounting Standards . In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes and statutory tax withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016. We are currently evaluating the impact this standard will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , which provides for a comprehensive change to lease accounting. The new standard requires that a lessee recognize a lease obligation liability and a right to use asset for virtually all leases of property, plant and equipment, subsequently amortized over the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, with a modified retrospective transition. We are currently evaluating the impact this standard will have on our consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes , which requires all deferred tax assets and liabilities, along with any related valuation allowance, to be classified as noncurrent on the balance sheet. The new standard is effective for fiscal years beginning after December 15, 2016, and may be applied prospectively or retrospectively, with early adoption permitted. We plan to adopt this standard in the first quarter of our fiscal 2017 and do not expect this to have a significant impact on our consolidated balance sheet. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Under the new standard, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2017, Apogee's fiscal 2019. We are currently evaluating the impact this standard will have on our consolidated financial statements.
