PART I

ITEM 1. BUSINESS

The Company

Apogee Enterprises, Inc. was incorporated under the laws of the State of Minnesota in 1949. The Company believes it is a world leader in certain technologies involving the design and development of value-added glass solutions for enclosing commercial buildings and framing art. Unless the context otherwise requires, the terms "Company," "Apogee," "we," "us" and "our" as used herein refer to Apogee Enterprises, Inc. and its subsidiaries.

The Company is comprised of four reporting segments:

• The Architectural Glass segment fabricates glass used in customized window and curtainwall systems comprising the outside skin of buildings. For fiscal 2015, our Architectural Glass segment accounted for approximately 34 percent of our net sales.

• The Architectural Services segment primarily installs and renovates customized aluminum and glass window and curtainwall systems comprising the outside skin of buildings. It also designs, engineers and fabricates a majority of the metal systems it installs. For fiscal 2015, our Architectural Services segment accounted for approximately 25 percent of our net sales.

• The Architectural Framing Systems segment designs, engineers and fabricates the aluminum frames used in customized aluminum and glass window, curtainwall, storefront and entrance systems comprising the outside skin and entrances of buildings. For fiscal 2015, our Architectural Framing Systems segment accounted for approximately 32 percent of our net sales.

• The Large-Scale Optical Technologies segment manufactures value-added glass and acrylic products primarily for the custom picture framing market. For fiscal 2015, our Large-Scale Optical Technologies segment accounted for approximately 9 percent of our net sales.

Financial information about the Company's segments and geographic regions can be found in Item 8, Note 16 to the Consolidated Financial Statements of the Company contained elsewhere in this report.

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited (Alumicor). Alumicor's results of operations are included in our Architectural Framing Systems segment. For further information, see "Acquisition of Alumicor" below.

Products and Services

Apogee provides distinctive value-added glass solutions for enclosing commercial buildings and framing art. We operate in four segments as described in the following paragraphs.

Architectural Glass, Architectural Services and Architectural Framing Systems Segments

All of these segments participate in various phases of the value chain to design, engineer, manufacture and install customized aluminum and glass window, curtainwall, and storefront and entrance systems for commercial buildings in the non-residential and high-end multi-family construction markets. Through complex processes, we add ultra-thin coatings to uncoated architectural glass to create a variety of aesthetic characteristics and different levels of solar energy management, especially important with the industry trend of increasingly energy-efficient buildings. We also laminate layers of glass and vinyl to create glass that helps protect against hurricanes and bomb blasts. Glass can also be tempered to provide additional strength. In addition, we have the ability to design and build windows, curtainwall, storefront and entrances using our customized aluminum and glass, or glass supplied by others. We also provide finishing services for the metal and plastic components used to frame architectural glass windows and walls and other products. Our installation services allow our customers to meet the timing and cost requirements of their jobs by providing efficiently designed quality window and wall systems and effectively managing the installation of the façade on their building projects.

Our product choices allow architects to create distinctive looks for office towers, hotels, education facilities and dormitories, health care facilities, government buildings, retail centers and multi-family residential buildings, while meeting functional requirements such as energy efficiency, impact resistance or sound control.

The following table describes the products provided by these segments.

Products	Product Attributes	Participating Segment	Description
High-Performance Glass	Custom Manufactured-to-Order	Architectural Glass	We offer a wide range of glass colors and high-performance coatings that allow us to create unique designs, achieve specific light transmission levels and provide solar control options for energy efficiency. Additional value-added processes, such as digital printing, silk-screening and heat soaking, can be incorporated into the glass. High-performance glass is typically fabricated into custom insulating units and/or laminated units to allow for installation into window, curtainwall, storefront or entrance systems.
Installation	New Construction and Renovation Services	Architectural Services	We install curtainwall, window, storefront and entrance systems for new commercial and institutional buildings as well as for renovation of existing buildings. By integrating technical capabilities, project management skills and field installation services, we provide design, engineering, fabrication and installation expertise for the building envelope to building owners, architects and general contractors.
Aluminum Framing	Standard, Custom and Engineered-to-Order	Architectural Framing Systems and Architectural Services	Varying degrees of customization of our window, curtainwall, storefront and entrance systems are available depending on the customer's project requirements. In-house engineering capabilities allow us to meet the architect's design requirements. Our window systems can be operable or non-operable. Our curtainwall systems may be unitized (shop fabricated) or field fabricated. Depending on the requirements, we paint or anodize the aluminum components.

All of the businesses within the Architectural Glass, Architectural Services and Architectural Framing Systems segments manufacture their products to order. Products are shipped to the job site or other location where further assembly or installation may be required by the respective segment's customers.

Large-Scale Optical Technologies (LSO) Segment

The LSO segment provides coated glass and acrylic for use in custom picture framing and fine art applications. The variables in the glass and acrylic used for picture framing products are the size and coatings to give the product UV protection, anti-reflective properties and/or security features. The following table describes the products provided by the LSO segment.

Products and Services	Product Attributes	Description
Value-Added Picture Framing Glass and Acrylic	UV, Anti-Reflective and/ or Security Features	Our coatings reduce the reflectivity of picture framing glass and protect pictures and art from the sun's damaging UV rays. Anti-reflective coatings on acrylic reduce glare and static charge on the surface.

Product Demand and Distribution Channels

Architectural Glass, Architectural Services and Architectural Framing Systems Segments

Our architectural products and services are used in a subset of the construction industry that is differentiated by building type, level of customization required, customers, geographic location and project size. Published data is not readily available for the specific segments that we serve; however, we estimate demand by analyzing data for the overall U.S. and Canadian construction industry.

Building type - The construction industry is typically segmented into residential construction and non-residential construction, which includes commercial, industrial and institutional construction. Apogee is a leading supplier of architectural glass and metal framing products, as well as installation services, to the non-residential construction industry. Our products and services are primarily used in commercial buildings (office towers, hotels and retail centers) and institutional buildings (education facilities and dormitories, health care facilities and government buildings), as well as high-end multi-family buildings (a subset of residential construction).

Level of customization - Most projects have some degree of customization, as the end product or service is based on customer-specified requirements for aesthetics and performance, and designed to satisfy local building codes. All of our Architectural Glass, Architectural Services and Architectural Framing Systems businesses are involved in transforming glass, aluminum or other materials to create customized window, curtainwall, storefront and/or entrance systems that meet customer specifications. The only constant is the base materials of the products and the processes we utilize to fabricate, manufacture and/or install the products.

5

Customers and distribution channels - Our customers and those that influence the projects include architects, building owners, general contractors and glazing subcontractors. Our high-performance architectural glass is marketed using a direct sales force and independent sales representatives. Our installation and renovation services are marketed by a direct sales force, primarily in the metropolitan areas we serve in the United States and also where we have the ability to work with our customers in other U.S. markets. We market our custom and standard windows, curtainwall, storefront and entrance systems using a combination of a direct sales force, independent sales representatives and distributors.

Geographic location - From our glass fabrication locations in the U.S., we primarily supply products to customers in the U.S., with some international distribution of our high-performance architectural glass. We estimate the U.S. demand for architectural glass fabrication in non-residential buildings is approximately $1.3 billion in annual sales. From our Brazilian glass fabrication facility, we primarily supply architectural glass in Brazil, where we estimate demand to be approximately $0.3 billion in annual sales. Our aluminum framing systems, including windows, curtainwall, storefront and entrances, are marketed in the U.S. and Canada, where we estimate demand is approximately $2.8 billion in annual sales.

We estimate the U.S. demand for installation services is approximately $10.5 billion in annual sales. Within the installation services industry, Apogee is one of only a few companies to have a national presence, with 11 offices and satellite offices serving multiple U.S. geographies. We estimate that we are able to service approximately 60 percent of the total installation demand from our existing locations and our ability to travel to other geographies where we do not have a local presence. Although installation of building glass in new commercial and institutional construction projects is the primary focus of our business, we also offer installation retrofits or renovations for the outside skin of older commercial and institutional buildings.

Project size - The projects on which our Architectural Glass, Architectural Services and Architectural Framing Systems segments bid and work vary in size. Our high-performance Architectural Glass fabrication products primarily serve mid-size to monumental high-profile projects. Our Architectural Services segment serves mid-size projects and the Architectural Framing Systems segment targets mid-size and small projects.

LSO Segment

The Company's Tru Vue brand is the largest domestically manufactured brand for value-added glass and acrylic for custom picture framing. Through the Company's leadership, the custom picture framing industry continues to convert from clear glass to value-added glass and acrylic. Under this brand, products are distributed primarily in North America through regional and national retail chains, as well as through local picture framing shops via an independent distribution network. The Company has also been successful in supplying products to museums and public and private galleries. We also have distribution in Europe and other international geographies through independent distributors; we view this as a focus area for future growth of this segment.

Warranties

We offer product and service warranties that we believe are competitive for the markets in which our products and services are sold. The nature and extent of these warranties depend upon the product or service, the market and, in some cases, the customer being served. Our standard warranties are generally from two to 10 years for our architectural glass, curtainwall and window system products, while we generally offer warranties of two years or less on our other products and installation services. In the event of a claim against a product for which we have received a warranty from the supplier, we pass the claim back to our supplier. Although we carry liability insurance with very high deductibles for product failures, we reserve for warranty exposures, as our insurance does not cover warranty claims. There can be no assurance that our insurance will be sufficient to cover all product failure claims in the future; that the costs of this insurance and the related deductibles will not increase materially; or that liability insurance for product failures will be available on terms acceptable to the Company in the future.

Sources and Availability of Raw Materials

Materials used within the Architectural Glass and Architectural Framing Systems segments include raw glass, aluminum billet and extrusions, vinyl, metal targets, insulated glass spacer frames, silicone, plastic extrusions, desiccant, chemicals, paints, lumber and urethane. Within the Architectural Services segment, materials used include fabricated glass, aluminum extrusions, silicone, plastic extrusions and fabricated metal panels. The LSO segment uses glass, hard-coated acrylic, acrylic substrates, metal targets, coating materials and chemicals.

Glass manufacturers have applied surcharges to the cost of glass over the past several years to help offset increases in energy and fuel costs, which we are generally able to pass on to our customers through surcharges. We have also seen recent volatility in the cost of aluminum that is used in our window, storefront, entrance and curtainwall systems. Where possible, we have passed the changes in cost of materials on to our customers in the form of pricing adjustments and/or surcharges.

A majority of our raw materials are readily available from a variety of domestic and international sources. While certain glass products may only be available at certain times of the year, all standard glass types and colors are available throughout the year

6

in reasonable quantities from multiple suppliers. Although we expect glass supply to become tighter in the U.S. due to the recent economic upturn across many industries that consume glass, including automotive manufacturing, residential construction and non-residential construction, no supplier delays or shortages are anticipated.

Trademarks and Patents

The Company has several trademarks and trade names that we believe have significant value in the marketing of our products, including APOGEE^®. Trademark registrations in the United States are generally for a term of 10 years, renewable every 10 years as long as the trademark is used in the regular course of trade.

Within the Architectural Glass segment, VIRACON^®, VIRACON VUE-50^®, DIGITALDISTINCTIONS^®, ROOMSIDE^®, EXTREMEDGE^®, BUILDING DESIGN^® and STORMGUARD^® are registered trademarks. GLASS IS EVERYTHING™, VIRASPAN™, CLEAR POINT™ and CYBERSHIELD™ are unregistered trademarks. In addition, GLASSEC^®, INSULATTO^® and BLINDATTO^® are registered trademarks in Brazil. GLASSECVIRACON^™ is an unregistered trademark in Brazil.

Within the Architectural Services segment, HARMON^®, HARMON GLASS^®, HI - 7000^® and INNOVATIVE FACADE SOLUTIONS^® and are registered trademarks. UCW-8000™, HI-8500™, HI-9000™, SMU-6000™ and HPW-250™ are unregistered trademarks.

Within the Architectural Framing Systems segment, LINETEC^®, WAUSAU WINDOW AND WALL SYSTEMS^®, TUBELITE^®, ADVANTAGE BY WAUSAU^®, FINISHER OF CHOICE^®, THERML=BLOCK^®, MAXBLOCK^®, DFG^®, ECOLUMINUM^®, ALUMINATE^®, GET THE POINT!^® and FORCEFRONT^® are registered trademarks. CUSTOM WINDOW™, INVENT™, INVENT.PLUS™, INVENT RETRO™, INVISION™, CLEARSTORY™, EPIC™, HERITAGE™, VISULINE™, SEAL™ and SUPERWALL™ are unregistered trademarks. ALUMICOR™ and BUILDING EXCELLENCE^TM are unregistered trademarks in Canada.

Within the LSO segment, TRU VUE^®, CONSERVATION CLEAR^®, CONSERVATION MASTERPIECE ACRYLIC^®, CONSERVATION REFLECTION CONTROL^®, ULTRAVUE^®, MUSEUM GLASS^®, OPTIUM^®, PREMIUM CLEAN^®, REFLECTION CONTROL^®, AR REFLECTION - FREE^®, TRU VUE AR^®, OPTIUM ACRYLIC^®, OPTIUM MUSEUM ACRYLIC^®, CONSERVATION MASTERPIECE^® and STATICSHIELD^® are registered trademarks. TRULIFE™ and VISTA AR™ are unregistered trademarks.

The Company has several patents pertaining to our glass coating methods and products, including our UV coating and etch processes for anti-reflective glass for the picture framing industry. Despite being a point of differentiation from its competitors, no single patent is considered to be material to the Company.

Seasonality

The North American businesses in our Architectural Glass, Architectural Services and Architectural Framing Systems segments experience a slight seasonal effect following the commercial construction industry. Our Brazilian Architectural Glass segment business does not have a significant seasonal trend. A bigger impact to net sales is the fact that the construction industry is highly cyclical in nature and can be influenced differently by the effects of the local economies in geographies where our products are marketed.

Within the LSO segment, picture framing glass and acrylic sales tend to increase in the September to December timeframe. However, the timing of customer promotional activities may offset some of this seasonal impact.

Working Capital Requirements

Trade accounts receivable is the largest component of working capital for the Company, including receivables relating to contractual retention amounts that can be outstanding throughout the project duration within the Architectural Services segment. Payment terms offered to our customers are similar to those offered by others in the industry. For the Architectural Glass and Architectural Framing Systems segments, inventory requirements are not significant since these businesses make-to-order rather than build-to-stock for the majority of their products. As a result, inventory levels follow customer demand for the products produced.

Since the LSO segment builds-to-stock for the majority of its products, it requires greater inventory levels to meet the demands of its customers.

7

Dependence on a Single Customer

We do not have any one customer that exceeds 10 percent of the Company's consolidated net sales. However, there are important customers within each of our segments; the loss of one or more customers could have an adverse effect on the Company.

Backlog

Backlog represents the dollar amount of revenues we expect to recognize in the future from firm contracts or orders received, as well as those that are in progress. Backlog is not a term defined under generally accepted accounting principles and is not a measure of contract profitability. We include a project within our backlog at the time a signed contract or a firm purchase order is received, generally as a result of a competitive bidding process. Backlog by reporting segment at February 28, 2015, November 29, 2014 and March 1, 2014 was as follows:

(In thousands)	February 28, 2015			November 29, 2014			March 1, 2014
Architectural Glass	$	137,432		$	151,221		$	73,206
Architectural Services	287,473			268,696			187,471
Architectural Framing Systems	77,666			88,070			72,634
Large-Scale Optical	2,107			2,100			870
Intersegment eliminations	(13,886		)	(16,173		)	(4,546		)
Total Backlog	$	490,792		$	493,914		$	329,635

We expect approximately $393.4 million, or 80 percent, of our February 28, 2015 backlog to be recognized in fiscal 2016, with the balance to be recognized in fiscal 2017 and beyond. We view backlog as an important statistic in evaluating the level of sales activity and short-term sales trends in our business. However, as backlog is only one indicator, and is not an effective indicator of our ultimate profitability, we do not believe that backlog should be used as the sole indicator of future earnings of the Company.

Competitive Conditions

Architectural Glass, Architectural Services and Architectural Framing Systems segments

The markets served by the Architectural Glass, Architectural Services and Architectural Framing Systems segments are very competitive, price and lead-time sensitive, and primarily affected by changes in the North American commercial construction industry, as well as changes in general economic conditions. Additionally, due to the Architectural Glass segment's operations in Brazil, it is impacted by the commercial construction industry and general economic conditions in Brazil and the surrounding region.

Interest rates, credit availability for commercial construction projects, material costs, employment rates, office vacancy rates, building construction starts and office absorption rates are key indicators to the commercial construction market conditions. As each of these economic indicators moves favorably, our businesses typically experience sales growth, and vice-versa.

These segments primarily serve the custom portion of the commercial construction industry, which is generally highly fragmented. The primary competitive factors are price, product quality, reliable service, on-time delivery, warranty and the ability to provide technical engineering and design services. There is potential to offset some competitive pressures in the market for newly constructed buildings through increased renovation of the exteriors of commercial and institutional buildings using some of our segments' products and services due to their premium energy-efficiency properties.

We believe that our domestic competition does not provide the same level of custom coatings to the industry as our Architectural Glass segment, but regional glass fabricators can provide somewhat similar products with similar attributes. Regional glass fabricators incorporate high performance, post-temperable glass products, procured from primary glass suppliers, into their insulated glass products. The availability of these products has enabled regional glass fabricators in some cases to bid on more complex projects than in the past. Since we typically target the more complex projects, we have encountered increased competition from these regional glass fabricators. In certain regions of the U.S., we encounter competition from international competitors on complex projects.

When providing glass installation services, our Architectural Services segment largely competes against regional and local construction companies and installation contractors, and periodically against other larger national companies. The commercial window and storefront manufacturing industry is highly fragmented and our Architectural Framing Systems segment competes against several major aluminum window and storefront manufacturers. Our architectural finishing business competes against regional paint and anodizing companies.

8

Our businesses in the Architectural Glass, Architectural Services and Architectural Framing Systems segments maintain significant relationships with architects, who influence the selection of products and services on a project. Additionally, throughout a construction project, the Architectural Services segment must maintain significant relationships with general contractors, who are the segment's direct customers. This is due to the high degree of dependence on general contractors and architects for project initiation and development of specifications. Additionally, the timing of a project depends on the schedule established by the general contractors and their ability to maintain this schedule. If a general contractor fails to keep a construction project on its established timeline, the timing and profitability of the project could be negatively impacted.

LSO Segment

Product attributes, pricing, quality, marketing, and marketing support are the primary competitive factors in the LSO segment. The Company's competitive strengths include our excellent relationships with customers and the performance provided by our unique value-added products. While there is significant price sensitivity in regard to sales of clear glass to picture framers, there is somewhat less price sensitivity on certain of our value-added glass products due to their unique attributes. There is competition in North America with European imports of certain valued-added products for picture framing.

Research and Development

The amount spent on research and development activities was $6.5 million, $7.8 million and $6.8 million in fiscal 2015, 2014 and 2013, respectively. Of this amount, $2.4 million, $2.1 million and $1.6 million, respectively, was focused primarily upon design of custom window and curtainwall systems in accordance with customer specifications and is included in cost of sales in the accompanying consolidated financial statements.

Environment

We use hazardous materials in our manufacturing operations, and have air and water emissions that require controls. As a result, we are subject to stringent federal, state and local regulations governing the storage, use and disposal of wastes. We contract with outside vendors to collect and dispose of waste at our production facilities in compliance with applicable environmental laws. In addition, we have procedures in place that we believe enable us to properly manage the regulated materials used in our manufacturing processes and wastes created by the production processes, and we have implemented a program to monitor our compliance with environmental laws and regulations. Although we believe we are currently in material compliance with such laws and regulations, current or future laws and regulations could require us to make substantial expenditures for compliance with chemical exposure, waste treatment or disposal regulations. We spent approximately $0.2 million, $0.5 million and $0.1 million in fiscal 2015, 2014 and 2013, respectively, to reduce wastewater solids and hazardous air emissions at our facilities. We expect to incur costs to continue to comply with laws and regulations in the future for our ongoing manufacturing operations but do not expect these to be material to our financial statements.

As part of the acquisition of Tubelite Inc. (Tubelite) on December 21, 2007, we acquired a manufacturing facility which has historical environmental conditions. We believe that Tubelite is a “responsible party” for certain of these historical environmental conditions, and the Company is working to remediate those conditions. The Company believes the remediation activities can be conducted without significant disruption to manufacturing operations at this facility. As of February 28, 2015, the environmental reserve balance was $1.8 million.

Employees

The Company employed 4,802 and 4,266 persons on February 28, 2015 and March 1, 2014, respectively. At February 28, 2015, 416 of these employees were represented by U.S. labor unions and 294 of these employees were represented by labor unions in Brazil.

Acquisition of Alumicor

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited, a privately held business, for $52.9 million, including cash acquired of $1.6 million. Alumicor is a window, storefront, entrance and curtainwall company primarily serving the Canadian commercial construction market. Alumicor's results of operations are included in the Architectural Framing Systems segment. Item 8, Note 6 of the Notes to the Consolidated Financial Statements contains further information regarding this acquisition.

International Sales

Information regarding export and international sales is included in Item 8, Note 16 of the Notes to the Consolidated Financial Statements.

ITEM 1A. RISK FACTORS

Our business faces many risks. Any of the risks discussed below, or elsewhere in the Form 10-K or our other filings with the Securities and Exchange Commission, could have a material adverse impact on our business, financial condition or results of operations.

General global economic and business conditions could negatively affect our results.

Our Architectural Glass, Architectural Services and Architectural Framing Systems segments are dependent on global economic conditions and the cyclical nature of the North American commercial construction industry. The commercial construction industry is impacted negatively by volatility in global financial markets, including, among other things, volatility in securities prices, availability of credit, unemployment rates, consumer confidence, interest rates and commodity prices. To the extent changes in these factors negatively impact the overall commercial construction industry, our revenue and profits could be significantly reduced.

Our Architectural Glass segment's operation located in Brazil is subject to the economic, political and tax conditions prevalent in the region. The economic conditions in this region are subject to different growth expectations, market weaknesses and business practices than seen in the U.S. We cannot predict how changing economic conditions in this region will impact our financial results.

Our LSO segment depends on the strength of the retail custom picture framing industry. This industry is highly dependent on consumer confidence and the conditions of the U.S. economy. If consumer confidence declines, whether as a result of an economic slowdown, uncertainty regarding the future or other factors, our use of these strategies may not be as successful in the future, resulting in a potential decrease in net sales and operating income.

Unfavorable fluctuations in foreign currency exchange rates could negatively impact our results and financial position.

Our subsidiaries in Canada and Brazil report their results of operations and financial position in their relevant functional currencies, which are then translated into U.S. Dollars. This translated financial information is included in our consolidated financial statements. The strengthening of the U.S. Dollar in comparison to these functional currencies could have a negative impact on our results and financial position.

New competitors or specific actions of our existing competitors could adversely impact our industry position and future results.

All of our operating segments operate in competitive industries where the actions of our existing competitors or new competitors could result in a loss of customers or share of customers' demand. Changes in our competitors' products, prices or services could negatively impact our share of demand, net sales or margins.

Our Architectural Glass and Architectural Framing Systems segments have seen an increase in imports of competitive products from lower-cost, international suppliers that, if this were to continue, could negatively impact our net sales and margins. Our LSO segment competes with several international specialty glass manufacturers that have traditionally not penetrated the U.S. custom picture framing industry. Although these LSO competitors have not been able to meet the specification level of our products, upgrades to our competitor's products could have a negative impact on net sales or margins.

Our ability to effectively utilize our manufacturing capacity could adversely impact future results.

Near-term performance depends, to a significant degree, on our ability to increase and appropriately utilize available production capacity. The failure to successfully maintain existing capacity, invest in additional physical capacity and recruit necessary manufacturing labor could adversely affect our operating results.

Product quality issues could negatively impact demand for our products and future profitability.

We manufacture and/or install a significant portion of our products based on the specific requirements of each customer. We believe that future orders of our products or services will depend on our ability to maintain the performance, reliability and quality standards required by our customers. If our products or services have performance, reliability or quality problems, or products are installed using incompatible glazing materials or installed improperly, we may experience additional warranty and service expense; reduced or canceled orders; diminished pricing power; higher manufacturing or installation costs; or delays in the collection of accounts receivable. Additionally, performance, reliability or quality claims from our customers, with or without merit, could result in costly and time-consuming litigation that could require significant time and attention of management and involve significant monetary damages that could negatively impact our financial results.

Project management and installation issues could negatively impact future results.

The Architectural Services segment is typically awarded fixed-price contracts for installation services. Often, bids are required before all aspects of a construction project are known. An underestimate in the amount of labor required and/or cost of materials for a project; a change in the timing of the delivery of product; difficulties or errors in execution; use of incompatible glazing materials; or significant project delays, caused by us or other trades, could result in failure to achieve the expected results. Any such issues could result in losses on individual contracts that could impact our operating results.

Our future profitability and cash flow are dependent on realizing expected government incentives.

We have made commitments to expand certain manufacturing facilities and make investments in new manufacturing capabilities. Contributing to the decision to make such investments was the availability of federal, state and local incentives including tax credits, tax increment financing and grants. If the Company is not able to realize the benefits of planned incentive packages, future operating results could be negatively impacted.

A shift in consumer preferences could negatively impact the demand for our products.

Any change in customer preference, architectural trends or building codes that reduces window-to-wall ratios in non-residential construction would negatively impact net sales and operating income in our Architectural Glass, Architectural Services and Architectural Framing Systems segments. The LSO segment depends on U.S. consumers framing art and other decorative items. Any shift in customer preference away from framed art to other forms of decorative media could negatively impact future net sales and operating income in the LSO segment.

The loss of a significant customer in the LSO segment could adversely affect our results.

The LSO segment is highly dependent on a relatively small number of customers for its sales. We expect to continue deriving a significant portion of our net sales from a small number of customers. Accordingly, loss of a significant customer or a significant reduction in pricing, or a shift to a less favorable mix of value-added picture framing glass or acrylic products for one of those customers could materially reduce LSO net sales and operating results.

11

Our results can be volatile and differ significantly from our expectations and the expectations of analysts.

Our net sales and operating results may differ from Company-provided guidance and the expectations of securities analysts or investors in future periods. Our annual net sales and operating results may vary depending on a number of factors, including, but not limited to, fluctuating customer demand, delay or timing of shipments, construction delays or cancellations due to lack of financing for construction projects, changes in product and project, and market acceptance of new products. Manufacturing or operational difficulties that may arise due to quality control, or unplanned operational downtime may also adversely impact our annual net sales and operating results. In addition, competition, including new entrants into our markets, the introduction of new products by competitors, adoption of competitive technologies by our customers, or competitive pressures on prices of our products and services, could adversely impact our annual net sales and operating results. Finally, our annual net sales and operating results may vary depending on raw material pricing and the potential for disruption of supply, or changes in legislation that could have an adverse impact on our labor or other costs. Our failure to meet net sales and operating result expectations would likely adversely affect the market price of our common stock.

We retain significant risk through self-insurance programs.

We obtain third-party insurance for potential losses from general liability, employment practices, workers' compensation and automobile liability risk. However, a high amount of risk is retained on a self-insured basis through a wholly-owned insurance subsidiary. Therefore, a material product liability event, such as a material rework event, could have a material adverse effect on our operating results.

Difficulties with our information technology systems and security could adversely affect our results.

We have many information technology systems that are important to the operation of our businesses. These systems are used to process, transmit, and store electronic information, and to manage or support a variety of business processes and activities. We could encounter difficulties in developing new systems and maintaining existing systems. Such difficulties could lead to significant additional expenses and/or disruption in business operations that could adversely affect our results.

Additionally, information technology security threats are increasing in frequency and sophistication. These threats pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data. Should such an attack succeed, it could lead to the compromise of confidential information, manipulation and destruction of data, production downtimes, disruption in the availability of financial data, or misrepresentation of information via digital media. The occurrence of any of these events could adversely affect our reputation, and could result in litigation, regulatory action, potential liability, and increased costs and operational consequences of implementing further data protection matters.

We use hazardous chemicals in the production of our products and are thus subjected to changes in environmental legislation.

We use hazardous chemicals in producing our products. One of our facilities has certain historical environmental conditions that we believe require remediation. Our inability to remediate the historical environmental conditions at the facility at or below the amounts reserved, therefore, could have a material adverse impact on future financial results. Additionally, we are subject to a variety of local, state and federal governmental regulations relating to storage, discharge, handling, emission, generation and disposal of toxic or other hazardous substances used to manufacture our products, compliance with which is expensive. Our failure to comply with current or future environmental regulations could result in the imposition of substantial fines, suspension of production, alteration of our manufacturing processes or increased costs. Our financial results could also be adversely impacted by rising energy and material costs associated with environmental regulations.

A loss of key personnel could negatively impact near-term results.

Our success depends on the skills, experience and efforts of our executive management and other key personnel. If, for any reason, one or more senior executives or key personnel were not to remain active in our Company, our financial results could be adversely affected.

ITEM 3. LEGAL PROCEEDINGS

The Company has been 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 has also been subject to litigation arising out of employment practices, workers' compensation, general liability 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.

Overview

We are a leader in certain technologies that provide distinctive solutions for enclosing commercial buildings and framing art. The Company's four reportable segments are: Architectural Glass, Architectural Services, Architectural Framing Systems and Large-Scale Optical (LSO).

• Architectural Glass segment consists of Viracon, a fabricator of coated, high-performance architectural glass for global markets.

• The Architectural Services segment consists of Harmon, one of the largest U.S. full-service building glass installation and renovation companies; it 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 companies design, engineer, fabricate and finish the aluminum frames used in customized aluminum and glass window, curtainwall, storefront and entrance systems comprising the outside skin and entrances of commercial and institutional buildings. We have aggregated four operating segments into the Architectural Framing Systems reporting segment based upon their similar products, customers, distribution methods, production processes and economic characteristics: Wausau Window and Wall Systems, a manufacturer of standard and custom aluminum window systems and curtainwall for the North American commercial construction and historical renovation markets; Tubelite, a fabricator of aluminum storefront, entrance and curtainwall products for the U.S. commercial construction industry; Alumicor, a fabricator of aluminum storefront, entrance, curtainwall and window products for the Canadian commercial construction industry; and Linetec, a paint and anodize finisher of architectural aluminum and PVC shutters for U.S. markets.

• LSO segment consists of Tru Vue, a manufacturer of value-added glass and acrylic for the custom picture framing and fine art markets.

The following highlights the results for fiscal 2015:

• Consolidated revenues increased 21 percent over fiscal 2014, or 17 percent excluding the impact of Alumicor, and operating income was up 58 percent over last year. All four segments grew revenue and earnings.

• EPS was $1.72, including a $0.22 per share impact of a 48C tax credit. Excluding this item, adjusted EPS was $1.50, up 58 percent over the prior year.

• Architectural Glass segment revenues improved 18 percent over fiscal 2014 and operating income improved to $16.4 million, as compared to $3.9 million in the prior year.

• The Architectural Services segment revenues increased 13 percent over fiscal 2014 and operating income improved by 66 percent.

• The Architectural Framing Systems segment net sales improved 38 percent compared to fiscal 2014, or 24 percent organic growth when adjusting out the impact of Alumicor, and operating income was up 46 percent.

• The LSO segment revenues increased by 8 percent over fiscal 2014 while operating income grew slightly over prior-year levels.

• Consolidated backlog was $490.8 million at February 28, 2015, up 49 percent over the fiscal 2014 level.

Strategy

Architectural Glass, Architectural Services and Architectural Framing Systems Segments

These three segments serve the commercial construction market, which is highly cyclical. They participate in various phases of the value chain to design, engineer, manufacture and install customized aluminum and glass window, curtainwall, and storefront and entrance systems for commercial buildings - each with nationally recognized brands and leading positions in their target market segments.

18

The window, curtainwall and storefront systems manufactured by our Architectural Framing Systems segment, as well as the glass products fabricated by our Architectural Glass segment, are sold to installers who enclose commercial buildings, such as offices, hospitals, educational facilities, government facilities, high-end multi-family buildings and retail centers. We believe general contractors and architects value our ability to reliably deliver quality, customized window and curtainwall solutions. Their customers - building owners and developers - value the distinctive look, energy efficiency, and hurricane and blast protection features of our window and curtainwall systems. These attributes can contribute to higher lease rates, lower operating costs due to the energy efficiency of our value-added glass and aluminum systems, a more comfortable environment for building occupants, and protection for buildings and occupants from hurricanes and blasts.

Our Architectural Services segment fabricates and installs window and curtainwall systems on newly constructed commercial buildings, as well as providing large-scale retrofit services for the window and curtainwall systems on existing commercial buildings. We collaborate closely with our customers, the general contractors, to complete installation projects on time and on budget in order to minimize costly job-site labor overruns.

We look at several market indicators, such as office space vacancy rates, architectural billing statistics, employment and other macroeconomic indicators, to gain insight into the commercial construction market. One of our primary indicators is U.S. non-residential construction market activity as documented by Dodge Data & Analytics (Dodge) (formerly McGraw-Hill Construction), a leading independent provider of construction industry analysis, forecasts and trends. We utilize the information for the building types that we typically serve (office towers, hotels, retail centers, education facilities and dormitories, health care facilities, government buildings and high-end multi-family buildings) and adjust this information (which is based on construction starts) to align with our fiscal year and the lag that is required to account for when our products and services typically are initiated in a construction project - approximately eight months after project start. From the Dodge data, we believe that our U.S. markets had a compound annual growth rate of eight percent over our past three fiscal years, while our combined compound annual organic growth rate for our three architectural segments was 13 percent over that same period.

Our overall strategy in the Architectural Glass and Architectural Framing Systems segments is to deliver organic growth faster than our commercial construction markets. While our Architectural Services segment will continue to deliver organic growth, the strategy of this segment will be focused on project selection and improved project margins. We will grow through geographic expansion and entry into adjacent markets and product offerings, while remaining focused on distinctive solutions for enclosing commercial buildings. We draw upon our leading brands, energy-efficient products and reputation for high quality and service in pursuit of our strategies. We also aspire to lead our markets in the development of practical, energy-efficient products for new construction and renovation. We have introduced products and services designed to meet the growing demand for energy-efficient building materials. These products have included new energy-efficient glass coatings, thermally enhanced aluminum framing systems, and systems with a high percentage of recycled content.

While each of our operating segments has the ability to grow through geographic expansion and product line extension, we regularly evaluate business development opportunities in complementary markets. This strategy can take the form of acquisition or strategic alliances.

In recent years, we have increased our focus on the window and curtainwall retrofit and renovation market. We have seen increased interest from the non-residential and high-end multi-family building sectors in upgrading the façades and improving the energy efficiency of their buildings. We consider this to be a significant opportunity for Apogee in the coming years.

Additionally, we are constantly working to improve the efficiency and productivity of our manufacturing and installation operations. During fiscal 2014, we completed the initial roll-out of lean manufacturing principles to all of our operating units. In fiscal 2015, we continued to see increasing maturity of many of the lean manufacturing disciplines. We expect this initiative to continue to deliver gross margin expansion into the foreseeable future.

Lastly, we consistently evaluate capital investments to improve productivity and product development capabilities, as well as to provide appropriate manufacturing capacity to support growth.

LSO segment

Our basic strategy in this segment is to convert the custom picture framing market from clear uncoated glass and acrylic products to value-added products that protect art from UV damage while minimizing reflection from the glass, so that viewers see the art rather than the glass. We estimate that over 60 percent of the demand for U.S. custom picture framing glass has converted to value-added glass. Although we are finding it more difficult to further increase the use of value-added glass in the U.S. market, we continue to see conversion to value-added glass. We offer a variety of products with varying levels of reflection control and promote the benefits to consumers with point-of-purchase displays and other promotional materials.

19

We also participate in the global fine art sector, which includes demand from museums and private art collections. This sector appreciates the conservation and anti-reflective properties of our products, primarily our acrylic products. Acrylic is a preferred material in the fine art sector because the product is light weight, which allows its use with art that is much larger and for which weight is an important consideration. We will continue to expand our presence in this sector through international expansion and product line extensions.

Additionally, this is the third fiscal year where we have been executing on our strategy of increasing custom picture framing sales in selected geographies outside the U.S. We now have distributors in over 30 countries, mainly in Europe, that are serviced from our warehouse in the Netherlands and directly from the U.S. As we leverage our products and distribution network, we will grow at a faster pace internationally than in the U.S.

Results of Operations

Net Sales

(Dollars in thousands)	2015		2014		2013		2015 vs. 2014		2014 vs. 2013
Net sales	$	933,936	$	771,445	$	700,224	21.1	%	10.2	%

Fiscal 2015 Compared to Fiscal 2014

Sales increased to $933.9 million, up 21.1 percent over fiscal 2014 sales of $771.4 million. Organic growth was 16.9 percent, or $127.5 million, when excluding the sales generated by our Canadian storefront and entrance business, which was acquired in the third quarter of fiscal 2014. Organic growth came primarily from increased sales volume in our architectural-based segments due to increased commercial construction activity in the U.S. The Architectural Glass segment accounted for approximately 32 percent of the organic growth due to increased volumes and improved pricing. Increased volume in the U.S. window, storefront and finishing businesses in the Architectural Framing Systems segment accounted for approximately 30 percent of the growth. The remaining organic growth was attributable to volume growth in the Architectural Services business and an improved mix of value-added products in the LSO segment.

Fiscal 2014 Compared to Fiscal 2013

Sales grew 10.2 percent in fiscal 2014 to $771.4 million compared to $700.2 million in fiscal 2013. The inclusion of Alumicor sales since the date of acquisition accounted for 2 percentage points of this increase. Improved product mix and pricing in the Architectural Glass segment drove approximately 4 percentage points of the increase. Volume growth in the Architectural Services segment favorably impacted fiscal 2014 by about 2 percentage points and the remainder of the increase resulted from improved volume in our Architectural Framing segment's U.S. storefront and finishing businesses.

Fiscal 2015 Compared to Fiscal 2014

Gross profit improved 0.9 percentage points to 22.3 percent of sales in fiscal 2015 from 21.4 percent in fiscal 2014. The increase in gross margins was due to the impact of operating leverage on increased volume and improved pricing in the Architectural Glass segment, as well as operating leverage on increased volume in the window business within the Architectural Framing Systems

segment. These positive items were partially offset by manufacturing cost overruns in the Architectural Services Segment, increased aluminum costs in the U.S. and Canadian storefront and entrance businesses within the Architectural Framing Systems segment, and costs to restart the Utah facility in our Architectural Glass segment.

Selling, general and administrative (SG&A) spending for fiscal 2015 increased by $20.0 million over fiscal 2014, while SG&A as a percent of sales decreased to 15.5 percent in fiscal 2015 from 16.2 percent in fiscal 2014. The addition of our Canadian storefront and entrance business acquired in the third quarter of fiscal 2014 contributed approximately 30 percent of the increase in year-on-year spend. The remaining increase was due to increased incentive compensation on improved results, increased sales commissions from higher sales volumes and write-down of certain assets acquired in our window business in fiscal 2014.

Other income was $1.4 million for fiscal 2015 compared to a small expense in the prior-year period, mainly due to the receipt of the final distribution in the first quarter of fiscal 2015 related to a European business that was discontinued over 15 years ago.

Our effective tax rate for fiscal 2015 was 22.3 percent. The effective tax rate in fiscal 2015 includes a $6.4 million tax benefit from an energy-efficient investment credit under Section 48C of the Internal Revenue Code in the second quarter of this fiscal year, 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-efficiency investments throughout the United States. Excluding this credit, our effective tax rate would have been 32.2% in fiscal 2015, slightly higher than 29.6% in fiscal 2014, due to a lesser net benefit from tax reserve adjustments in the current year.

Fiscal 2014 Compared to Fiscal 2013

Gross profit improved as a percent of sales to 21.4 percent in fiscal 2014 from 20.8 percent in fiscal 2013. The improvement in gross margins was due to the margin impact of improved mix and pricing in the Architectural Glass segment, improved project margins in the Architectural Services segment and overall productivity improvements. These favorable items were partially offset by lower capacity utilization in the Architectural Framing System's window business related to an anticipated gap in the schedule for more complex projects.

Selling, general and administrative spending increased by $6.7 million in fiscal 2014 over fiscal 2013, while SG&A as a percent of sales decreased to 16.2 percent in fiscal 2014 from 16.9 percent in fiscal 2013. The increase in spending was primarily due to increased salaries and related benefits to support sales growth and geographic expansion, as well as other costs related to geographic expansion and acquisitions during fiscal 2014.

Segment Analysis

Architectural Glass

(In thousands)	2015			2014			2013
Net sales	$	346,471		$	293,810		$	266,456
Operating income (loss)	16,431			3,861			(4,391		)
Operating income (loss) as a percent of sales	4.7		%	1.3		%	(1.6		)%

Fiscal 2015 Compared to Fiscal 2014. Fiscal 2015 net sales of $346.5 million increased $52.7 million, or 17.9 percent, over fiscal 2014. The increase for the year was primarily due to increased volume and some improvement in pricing.

Operating income improved to $16.4 million in fiscal 2015, compared to $3.9 million in fiscal 2014, an improvement of $12.6 million. Operating margins improved to 4.7 percent in fiscal 2015 compared to 1.3 percent in fiscal 2014. As the commercial construction activity has increased, the Architectural Glass segment has benefited from operating leverage on volume growth and improved pricing. The segment also demonstrated positive manufacturing productivity that was partially offset by inefficiencies experienced as the business expanded its workforce to meet demand and costs incurred to restart the Utah facility.

Fiscal 2014 Compared to Fiscal 2013. Fiscal 2014 net sales increased $27.4 million to $293.8 million, or 10.3 percent over fiscal 2013. Improved mix and pricing in our U.S. and Brazilian businesses accounted for most of the increase. The remainder was due to volume growth in both our U.S. and Brazilian businesses, partially offset by a decline in our export volume.

Operating income of $3.9 million in fiscal 2014 was an $8.3 million improvement over the fiscal 2013 loss of $4.4 million. Operating margins improved to 1.3 percent in fiscal 2014 compared to negative 1.6 percent in fiscal 2013. The improvement in operating results was largely due to the impact of a better mix of higher value-added projects and improved pricing. The impact of volume growth and productivity improvements also contributed to the year-on-year increase in operating results.

Architectural Services

(In thousands)	2015			2014			2013
Net sales	$	230,650		$	203,351		$	186,570
Operating income (loss)	7,442			4,479			(1,008		)
Operating income (loss) as a percent of sales	3.2		%	2.2		%	(0.5		)%

Fiscal 2015 Compared to Fiscal 2014. Net sales of $230.7 million in fiscal 2015 increased $27.3 million, or 13.4 percent over fiscal 2014. The increase was due to volume from project timing and a general increase in project activity on stronger end markets. Operating income increased $3.0 million to $7.4 million compared to $4.5 million in fiscal 2014. Operating margin was 3.2 percent in fiscal 2015 compared to 2.2 percent in fiscal 2014. The improvements in operating results for the year were a result of operating leverage on the increased volume and increasing project margins due to our focus on project selection.

Fiscal 2014 Compared to Fiscal 2013. Fiscal 2014 net sales increased $16.8 million over fiscal 2013, a 9.0 percent increase. Volume growth in existing and expanded geographies was the driver of this growth. Fiscal 2014 operating income increased $5.5 million to $4.5 million compared to a loss of $1.0 million in fiscal 2013. Operating margin of 2.2 percent in fiscal 2014 was an improvement of 2.7 percentage points over fiscal 2013. The improved operating results were a result of better project margins, as we have worked through lower margin projects that were bid in the bottom of the market cycle, as well as strong execution on projects flowing through revenue.

Architectural Framing Systems

(In thousands)	2015			2014			2013
Net sales	$	298,395		$	216,059		$	191,137
Operating income	21,808			14,930			14,584
Operating income as a percent of sales	7.3		%	6.9		%	7.6		%

Fiscal 2015 Compared to Fiscal 2014. Fiscal 2015 net sales of $298.4 million increased $82.3 million, or 38.1 percent, over fiscal 2014. Organic growth, excluding our Canadian storefront and entrance business, was 23.7 percent. The organic growth in fiscal 2015 was due to double-digit volume increases at our three U.S. businesses in the segment, with the U.S. storefront and finishing businesses increasing penetration within their target sectors and geographies, the window business recovering from a prior-year gap in the schedule for complex projects, and an increase in volume due to market growth in our finishing business.

Fiscal 2015 operating income of $21.8 million was an increase of $6.9 million over the $14.9 million reported in fiscal 2014, and operating margins improved to 7.3 percent in fiscal 2015 from 6.9 percent in fiscal 2014. The increase in operating results was due to the impact of income growth in the U.S. window, finishing and storefront businesses resulting from increased volume and good execution. This improvement was slightly offset by the negative effect of higher aluminum costs in the U.S. and Canadian storefront businesses, and the impact of soft Canadian markets on the Canadian storefront business in the first half of the year.

Fiscal 2014 Compared to Fiscal 2013. Fiscal 2014 net sales increased $24.9 million, or 13.0 percent, over fiscal 2013.The addition of our Canadian storefront and entrance business accounted for approximately 8 percentage points of the increase for fiscal 2014. The remainder of the increase was due to improved volumes in the U.S. storefront and finishing businesses, partially offset by volume declines caused by an anticipated gap in the schedule for the window business.

Fiscal 2014 operating income of $14.9 million was up slightly over the $14.6 million reported in fiscal 2013, while operating margins decreased to 6.9 percent in fiscal 2014 from 7.6 percent in fiscal 2013. The favorable impact of increased volumes in the U.S. storefront and finishing businesses was partially offset by lower sales in the window business related to the anticipated gap in the schedule for more complex projects, resulting in lower capacity utilization. Additionally, the Canadian storefront business that was acquired late in fiscal 2014 delivered an operating loss due to acquisition costs.

Large-Scale Optical Technologies (LSO)

(In thousands)	2015			2014			2013
Net sales	$	87,693		$	81,127		$	79,947
Operating income	21,954			21,252			20,993
Operating income as a percent of sales	25.0		%	26.2		%	26.3		%

Fiscal 2015 Compared to Fiscal 2014. LSO fiscal 2015 net sales of $87.7 million were up $6.6 million, or 8.1 percent, over fiscal 2014 net sales of $81.1 million. The improvement compared to fiscal 2014 was due to a positive mix of higher value-added products on relatively flat volumes. Operating income of $22.0 million was up slightly over fiscal 2014 results of $21.3 million, while operating margins dropped to 25.0 percent in fiscal 2015 compared to 26.2 percent in fiscal 2014. The impact of the strong mix of value-added products was largely offset by increased incentive compensation and investments in new product development.

Fiscal 2014 Compared to Fiscal 2013. LSO revenues in fiscal 2014 increased slightly over fiscal 2013 to $81.1 million from $79.9 million. The improvement compared to fiscal 2013 was due to a positive mix of higher value-added products. Operating income of $21.3 million was relatively flat compared to fiscal 2013 levels and operating margins were consistent. The impact of the strong mix of higher value-added products was largely offset by increased promotional activities and investments for growth in new geographies and markets.

Consolidated Backlog

Backlog represents the dollar amount of revenues we expect to recognize in the future from firm contracts or orders received, as well as those that are in progress. Backlog is not a term defined under generally accepted accounting principles and is not a measure of contract profitability. We include a project within our backlog at the time a signed contract or a firm purchase order is received, generally as a result of a competitive bidding process. Backlog by reporting segment at February 28, 2015, November 29, 2014 and March 1, 2014 was as follows:

(In thousands)	February 28, 2015			November 29, 2014			March 1, 2014
Architectural Glass	$	137,432		$	151,221		$	73,206
Architectural Services	287,473			268,696			187,471
Architectural Framing Systems	77,666			88,070			72,634
Large-Scale Optical	2,107			2,100			870
Intersegment eliminations	(13,886		)	(16,173		)	(4,546		)
Total Backlog	$	490,792		$	493,914		$	329,635

We expect approximately $393.4 million, or 80 percent, of our February 28, 2015 backlog to be recognized in fiscal 2016, with the balance to be recognized in fiscal 2017 and beyond. We view backlog as an important statistic in evaluating the level of sales activity and short-term sales trends in our business. However, as backlog is only one indicator, and is not an effective indicator of our ultimate profitability, we do not believe that backlog should be used as the sole indicator of future earnings of the Company.

Acquisitions

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited, a privately held business, for $52.9 million, including cash acquired of $1.6 million. Alumicor is a window, storefront, entrance and curtainwall company primarily serving the Canadian commercial construction market. The purchase price allocation was based on the fair value of assets acquired and liabilities assumed and included total assets of $61.8 million, including goodwill and intangibles of $34.9 million, and total liabilities of $10.5 million. In the second quarter of fiscal 2014, we also acquired certain assets and liabilities of a window fabrication business as part of our strategy to grow through new products and new geographies. Both of these acquisitions are reported within our Architectural Framing Systems segment.

Operating activities. Cash provided by operating activities was $68.6 million in fiscal 2015, $52.9 million in fiscal 2014, and $40.5 million in fiscal 2013. Fiscal 2015 and 2014 operating cash flows were each positively impacted by the increased income reported for those fiscal years as compared to the respective prior-year periods.

Non-cash working capital (current assets, excluding cash and short-term available for sale securities and short-term restricted investments, less current liabilities, excluding current portion of long-term debt) was $97.5 million at February 28, 2015. This compares to $82.0 million at March 1, 2014, and $58.8 million at March 2, 2013. The increase in fiscal 2015 was due to our investment in working capital necessary to support sales growth. The change in fiscal 2014 was a result of including partial year results of Alumicor, growth in the base business and extending our geographic footprint in certain businesses.

Investing Activities. Investing activities used cash of $24.5 million in fiscal 2015, $44.0 million in fiscal 2014 and $57.1 million in fiscal 2013. The current year included capital investments of $27.2 million mainly to increase productivity, increase capacity and improve product development capabilities. Net sales of marketable securities and restricted investments generated $3.3 million of cash.

In fiscal 2014, we made capital investments of $41.9 million as we made investments for productivity and product development capabilities, including a new state-of-the-art coater in our Architectural Glass segment. We reduced our restricted investments by $23.9 million, as we released $10.0 million of cash held in escrow for the recovery zone facility bonds that was used to redeem the bonds and also released $12.0 million of cash collateral to unrestricted cash related to the letter of credit supporting these bonds. We decreased our investments in marketable securities by $26.5 million in fiscal 2014 to fund the acquisition of Alumicor.

During fiscal 2014, we completed two acquisitions as part of our strategy to grow through new products and new geographies. In the second quarter, we acquired certain assets and liabilities of a window fabrication business, which are included in the results of our window business within the Architectural Framing Systems segment. During the third quarter, we acquired the outstanding shares of Alumicor Limited; its results of operations are included within the Architectural Framing Systems segment.

In fiscal 2013, we made capital investments of $34.7 million for growth and productivity improvements, as well as equipment to support new product introductions, and maintenance capital. The net position of our investments for fiscal 2013 resulted in $17.6 million in net purchases as a result of generating excess cash through operating activities noted above. Net purchases of $4.5 million for restricted investments during fiscal 2013 were the result of $10.0 million of industrial development bonds (reflected in financing activities) that were made available for current and future investment in our storefront and entrance business in Michigan.

We expect fiscal 2016 capital expenditures to range from $45 to $50 million for investments to increase capabilities, capacity and productivity, as well as maintenance capital.

24

We continue to review our portfolio of businesses and their assets in comparison to our internal strategic and performance objectives. As part of this review, we may acquire other businesses, pursue geographic expansion, take actions to manage capacity, and/or further invest in, fully divest and/or sell parts of our current businesses.

At February 28, 2015, 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. We had a deferred gain of $2.8 million under the sale and leaseback transaction, which is included in the balance sheet as other current and non-current liabilities. The average annual lease payment over the life of the remaining lease is $1.0 million.

Financing Activities. Total outstanding borrowings at February 28, 2015 were $20.6 million, compared to $20.7 million at March 1, 2014 and $30.8 million at March 2, 2013. During the first quarter of fiscal 2014, $10.0 million of recovery zone facility bonds that had previously been issued for future investment in the Company's Architectural Glass fabrication facility in Utah were redeemed at par. Our debt consists of $20.4 million of industrial revenue bonds and $0.2 million of other debt. The industrial revenue bonds mature in fiscal years 2021 through 2043 and the other debt matures in fiscal years 2016 through 2021. There were small amounts of current debt at February 28, 2015 and March 1, 2014. At March 2, 2013, $10.0 million of the recovery zone facility bonds were classified as current as we repaid these bonds related to our Utah facility in early fiscal 2014. Our debt-to-total-capital ratio was 5.1 percent at February 28, 2015 and 5.5 percent at March 1, 2014.

During the fourth quarter of fiscal 2015, we entered into an amendment of our existing $100.0 million committed revolving credit facility. The amount of the facility was increased to $125.0 million; the expiration date was extended to December 2019; the letter of credit facility was reduced to $40.0 million from $50.0 million, the outstanding amounts of which decrease the available commitment; and the maximum debt-to-EBITDA ratio was increased to 3.00. No other provisions of the original agreement were materially amended by the amended credit agreement. No borrowings were outstanding under the facility as of February 28, 2015 or March 1, 2014.

The credit facility requires that we maintain a debt-to-EBITDA ratio of not more than 3.00. This ratio is computed quarterly, with EBITDA computed on a rolling four-quarter basis. The Company’s ratio was 0.22 at February 28, 2015. The credit facility also requires the Company to maintain a minimum level of net worth, as defined in the credit facility, based on certain quarterly financial calculations. The minimum required net worth computed in accordance with the credit facility at February 28, 2015 was $318.8 million, whereas the Company’s net worth as defined in the credit facility was $382.5 million. If the Company is not in compliance with either of these covenants, the lenders may terminate the commitment and/or declare any loan then outstanding to be immediately due and payable. At February 28, 2015, the Company was in compliance with the financial covenants of the credit facility.

In the second quarter of fiscal 2015, we entered into a Canadian Dollar $4.0 million revolving demand facility available to our Canadian storefront and entrance business. Borrowings under the facility are made available at the sole discretion of the lender and are payable on demand. Borrowings under the facility bear interest at rates specified in the credit agreement for the facility. We classify any outstanding balances under this demand facility as long-term debt, since outstanding amounts can be refinanced through our committed revolving credit facility. No borrowings were outstanding as of February 28, 2015.

During fiscal 2004, the Board of Directors authorized a share repurchase program of 1,500,000 shares of common stock. The Board of Directors increased this authorization by 750,000 shares in January 2008 and by 1,000,000 in October 2008. We purchased 203,509 shares under the program during fiscal 2015, for a total cost of $6.9 million; there were no share repurchases during fiscal 2014. We have purchased a total of 2,482,632 shares, at a total cost of $36.5 million, since the inception of this program. We have remaining authority to repurchase 767,368 shares under this program, which has no expiration date.

In addition to the shares repurchased under the repurchase plan, during fiscal 2015 and 2014 we also acquired $5.2 million and $3.6 million, respectively, of Company stock from employees in order to satisfy stock-for-stock option exercises or withholding tax obligations related to stock-based compensation, pursuant to terms of Board and shareholder-approved compensation plans.

From time to time, we acquire the use of certain assets, such as warehouses, automobiles, forklifts, vehicles, office equipment, hardware, software and some manufacturing equipment through operating leases. Many of these operating leases have termination penalties. However, because the assets are used in the conduct of our business operations, it is unlikely that any significant portion of these operating leases would be terminated prior to the normal expiration of their lease terms. Therefore, we consider the risk related to termination penalties to be minimal.

We have purchase obligations for raw material commitments and capital expenditures. As of February 28, 2015, these obligations totaled $158.9 million.

We expect to make contributions of $1.0 million to our defined-benefit pension plans in fiscal 2016, which will equal or exceed our minimum funding requirements.

As of February 28, 2015, we had $4.5 million and $1.8 million of unrecognized tax benefits and environmental liabilities, respectively. We expect approximately $0.7 million of the unrecognized tax benefits to lapse during the next 12 months. We are unable to reasonably estimate in which future periods the remaining unrecognized tax benefits and environmental liabilities will ultimately be settled.

At February 28, 2015, we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The Company’s $20.4 million of industrial revenue bonds are supported by $21.0 million of letters of credit that reduce availability of funds under our $125.0 million credit facility. The letters of credit by expiration period were as follows at February 28, 2015:

	Amount of Commitment Expiration Per Fiscal Period
(In thousands)	2016		2017		2018		2019		2020		Thereafter		Total
Standby letters of credit	$	8,653	$	12,329	$	—	$	—	$	—	$	2,500	$	23,482

In addition to the above standby letters of credit, which were primarily issued for our industrial revenue bonds, we are required, in the ordinary course of business, to provide surety or performance bonds that commit payments to our customers for any non-performance by us. At February 28, 2015, $76.9 million of our backlog was bonded by performance bonds with a face value of $274.0 million. Performance bonds do not have stated expiration dates, as we are 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.

We believe that current cash on hand and available capacity under our committed revolving credit facility, as well as the expected cash to be generated from future operating activities, will be adequate to fund our working capital requirements, planned capital expenditures and dividend payments over the next 12 months. We have total cash and short-term available-for-sale securities of $52.5 million, and $101.5 million available under our credit facility at February 28, 2015. We believe that this will provide us with the financial strength to continue our growth strategy as our end markets continue to improve.

Off-balance sheet arrangements. With the exception of operating leases, we had no off-balance sheet financing arrangements at February 28, 2015 or March 1, 2014.

Recently Issued Accounting Pronouncements

See New Accounting Standards set forth in Note 1 of the Notes to Consolidated Financial Statements under Item 8 of this Form 10-K for information pertaining to recently adopted accounting standards or accounting standards to be adopted in the future, which is incorporated by reference herein.

Critical Accounting Policies

Management has evaluated the accounting policies and estimates used in the preparation of the accompanying financial statements and related notes, and believes those policies and estimates to be reasonable and appropriate. We believe that the most critical accounting policies and estimates applied in the presentation of our financial statements relate to accounting for future events. Future events and their effects cannot be determined with absolute certainty. Therefore, management is required to exercise judgment both in assessing the likelihood that a liability has been incurred as well as in estimating the amount of potential loss. We have identified the following accounting policies as critical to our business and in the understanding of our results of operations and financial position:

Revenue recognition - Our standard product sales terms are “free on board” (FOB) shipping point or FOB destination, and revenue is recognized when title has transferred. However, our Architectural Services segment business enters into fixed-price contracts for full-service commercial building glass installation and renovation services, which are accounted for as construction-type 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. The contracts entered into clearly specify the enforceable rights of the parties, the consideration and the terms of settlement, and both parties can be expected to satisfy all obligations under the contract. During fiscal 2015, approximately 25 percent of our consolidated sales were recorded on a percentage-of-completion basis. Under this methodology, 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. Given our ability to make reasonable estimates of our total contract revenues and total contract costs, we believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of precision in measuring progress toward completion of the installation contracts. 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 when customers have approved them. A significant number of estimates are used in these computations.

Goodwill impairment - To determine if there has been any impairment in accordance with accounting standards, we evaluate the goodwill on our balance sheet annually or more frequently if impairment indicators exist through a two-step process. In step one, we value each of our reporting units and compare these values to the reporting units' net book value, including goodwill. If the fair value is less than the net book value, we perform step two, which determines the amount of goodwill to impair. Each of our seven business units represents a reporting unit under applicable accounting standards. We were not required to perform step two for fiscal 2015; the estimated fair value of each of the reporting units significantly exceeded their book value utilizing the discounted cash flow methodology at February 28, 2015.

Although we consider public information for transactions made on businesses similar to ours, since there were no market comparables identified, we base our determination of fair value using a discounted cash flow methodology that involves significant judgments based upon projections of future performance. In developing our discounted cash flow analysis, assumptions about future revenues and expenses, capital expenditures and changes in working capital are based on our annual operating plan and long-term business plan for each of our reporting units. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions and growth expectations for the industries and end markets in which we participate. These assumptions are determined over a five-year, long-term planning period. The five-year growth rates for revenues and operating profits vary for each reporting unit being evaluated. Revenues and operating profit beyond the five-year period are projected to grow at a nominal perpetual growth rate for all reporting units. The discount rate calculations are determined by assuming a company beta, market premium risk, size premium, the cost of debt and debt-to-capital ratio of a market participant.

27

A significant change in the factors noted above could cause us to reduce the estimated fair value of some or all of our reporting units and recognize a corresponding impairment of our goodwill in connection with a future goodwill impairment test. There can be no assurances that these forecasts will be attained. Adverse changes in strategy, market conditions or assumed market capitalization may result in an impairment of goodwill.

Reserves for disputes and claims regarding product liability and warranties - From time to time, 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. The time period from when a claim is asserted to when it is resolved, either by dismissal, negotiation, settlement or litigation, can be several years. While we maintain product liability insurance, the insurance policies include significant self-retention of risk in the form of policy deductibles. In addition, certain claims could be determined to be uninsured. We reserve based on our estimates of known claims, as well as on anticipated claims for possible product warranty and rework costs based on historical product liability claims as a ratio of sales.

Self-insurance reserves - We obtain substantial amounts of commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, architect's and engineer's errors and omissions risk, product re-work and other miscellaneous coverages. However, an amount of risk is retained on a self-insured basis through a wholly-owned insurance subsidiary; as a result, a material construction project rework event could have a material adverse effect on our operating results. Reserve requirements are established based on actuarial projections of ultimate losses.

Income taxes - We record a tax provision for the anticipated tax consequences of the reported results of operations. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those deferred tax assets and liabilities are expected to be realized or settled. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with management's expectations could have a material impact on the Company's financial condition and operating results.

As part of our ongoing financial reporting process, a collaborative effort is undertaken involving our management with responsibility for financial reporting, product and project management, quality, legal and tax, and outside advisors such as consultants, engineers, lawyers and actuaries. The results of this effort provide management with the necessary information on which to base its judgments on these future events and develop the estimates used to prepare the financial statements. We believe that the amounts recorded in the accompanying financial statements related to these events are based on the best estimates and judgments of Apogee management. However, outcomes could differ from our estimates and could materially adversely affect our future operating results, financial position and cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our investment portfolio consists of municipal bonds. At February 28, 2015, we had total investments of $11.0 million, which are considered available-for-sale securities. Although these investments are subject to the credit risk of the issuer and/or letter of credit issuer, we manage our investment portfolio to limit our exposure to any one issuer.

We do not use derivative financial instruments to manage interest rate risk or to speculate on future changes in interest rates. Accordingly, a rise in interest rates could negatively affect the fair value of our municipal bond portfolio. To manage our direct risk from changes in market interest rates, management actively monitors the interest-sensitive components of our balance sheet, primarily debt obligations and fixed income securities, as well as market interest rates, to minimize the impact of changes in interest rates on net earnings and cash flow.

The primary measure of interest rate risk is the simulation of net income under different interest rate environments. The approach used to quantify interest rate risk is a sensitivity analysis. This approach calculates the impact on net earnings, relative to a base case scenario, of rates increasing or decreasing gradually over the next 12 months by 200 basis points. This change in interest rates affecting our financial instruments at February 28, 2015 would result in an approximately $0.2 million impact to net earnings. The Company's investments exceeded its debt at February 28, 2015, so as interest rates increase, net earnings increase; as interest rates decrease, net earnings decrease.

In addition to the market risk related to interest rate changes, the commercial construction markets in which our businesses operate are highly affected by changes in interest rates and, therefore, significant interest rate fluctuations could materially impact our operating results.

Due to our Canadian storefront and Brazilian glass businesses, we conduct business in locations outside of the United States, and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar.

28

We generally do not use derivative financial instruments to manage these risks. The functional currency in each of our foreign operations is the local currency in the country of domicile. We manage these operating activities at the local level and revenues, costs, assets and liabilities are generally denominated in local currencies, thereby mitigating the risk associated with changes in foreign exchange. However, our results of operations and assets and liabilities are reported in U.S. dollars, and thus will fluctuate with changes in exchange rates between Canadian dollar, Brazilian real and the U.S. dollar.

Our domestic businesses generally sell within the United States, with sales made outside of the United States generally denominated in U.S. dollars.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management's Report on Internal Control over Financial Reporting

Management of Apogee Enterprises, Inc. and its subsidiaries (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) of the Securities Exchange Act of 1934. The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that (1) pertain to maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of February 28, 2015, using criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). The Company's management believes that, as of February 28, 2015, the Company's internal control over financial reporting was effective based on those criteria.

The Company's independent registered public accounting firm, Deloitte & Touche LLP, has issued a report on the effectiveness of the Company's internal control over financial reporting as of February 28, 2015. That report is set forth immediately following the report of Deloitte & Touche LLP on the consolidated financial statements included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Apogee Enterprises, Inc.

Minneapolis, MN

We have audited the accompanying consolidated balance sheets of Apogee Enterprises, Inc. and subsidiaries (the “Company”) as of February 28, 2015 and March 1, 2014, and the related consolidated results of operations, statements of comprehensive earnings, statements of cash flows, and statements of shareholders’ equity for each of the three years in the period ended February 28, 2015. Our audits also included the financial statement schedule listed in the Table of Contents at Item 15. These consolidated financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Apogee Enterprises, Inc. and subsidiaries at February 28, 2015 and March 1, 2014, and the results of their operations and their cash flows for each of the three years in the period ended February 28, 2015, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of February 28, 2015, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 29, 2015, expressed an unqualified opinion on the Company's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Apogee Enterprises, Inc.

Minneapolis, MN

We have audited the internal control over financial reporting of Apogee Enterprises, Inc. and subsidiaries (the “Company”) as of February 28, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of February 28, 2015, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule listed in the Table of Contents at Item 15 as of and for the year ended February 28, 2015, of the Company and our report dated April 29, 2015 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies and Related Data

Basis of Consolidation. The accompanying consolidated financial statements include the accounts of Apogee Enterprises, Inc., a Minnesota corporation, and all majority-owned subsidiaries (the Company). Transactions between Apogee and its subsidiaries have been eliminated in consolidation.

The results of Alumicor Limited (Alumicor), which the Company acquired on November 5, 2013, are included in the Company's Architectural Framing Systems segment. Refer to Note 6 for further information regarding the acquisition of Alumicor and its treatment in the consolidated financial statements.

GlassecViracon's fiscal year ends December 31 and its results are incorporated into the consolidated financial statements on a two-month lag. There were no significant intervening events that would have materially affected our consolidated financial statements had they been recorded during the year ended February 28, 2015.

Fiscal Year. Apogee's fiscal year ends on the Saturday closest to the last day of February. Fiscal 2015, 2014 and 2013 each consisted of 52 weeks.

Financial Instruments. Unless otherwise noted, the carrying amount of the Company's financial instruments approximates fair value.

Cash and Cash Equivalents. Investments with an original maturity of three months or less are included in cash and cash equivalents. Cash equivalents are stated at cost, which approximates fair value, and consist primarily of money market funds.

Investments. The Company has marketable securities consisting of high-quality municipal bonds. The securities are classified as “available for sale” and are carried at fair value based on prices from recent trades of similar securities. The Company tests for other than temporary losses on a quarterly basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If a decline in the fair value of a security is deemed by management to be other-than-temporary, the investment is written down to fair value, and the amount of the write-down is included in net earnings.

The Company also has investments in mutual funds as a long-term funding source for the deferred compensation plan. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

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.

During the fourth quarter of fiscal 2015, the Company changed its method of accounting for those inventories which were accounted for under the last-in, first-out (“LIFO”) method (53 percent of total fiscal 2014 inventories) to the FIFO method. The Company believes that this change is preferable as it provides uniformity across the Company's operations with respect to the method of inventory accounting, better reflects the current value of inventories on the consolidated balance sheets, aligns the accounting with the physical flow of inventory, and better matches revenues with associated expenses.

38

The change was applied retrospectively to March 3, 2012. The resulting impact to our consolidated balance sheets as of March 1, 2014 is as follows:

	March 1, 2014
(In thousands)	As Originally Reported		LIFO to FIFO Adjustment			Retrospectively Adjusted
Inventories, net	$	47,982	$	5,453		$	53,435
Current deferred tax assets	3,529		(815		)	2,714
Non-current deferred tax liabilities	7,403		1,164			8,567
Retained earnings	225,367		3,474			228,841

No retrospective adjustments were made to the consolidated results of operations or consolidated statements of cash flow as they were immaterial for all periods presented, resulting in an immaterial adjustment recorded to the consolidated results of operations and consolidated balance sheets during the fourth quarter of fiscal 2015 of approximately $0.1 million.

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 income as a reduction of or increase 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. The Company accounts for goodwill and intangible assets in accordance with applicable accounting standards.

The Company tests goodwill of each of its reporting units for impairment annually in connection with its fourth-quarter planning process or more frequently if impairment indicators exist. The Company has determined that each of its business units represents a reporting unit in accordance with applicable accounting standards. During the fourth quarter of fiscal 2015, the Company completed its annual impairment test using discounted cash flow methodologies for valuing its reporting units as no market comparables were identified. There have not been any material changes in the impairment loss assessment methodology made during the past three fiscal years. The estimates of fair value for the reporting units were found to be in excess of their carrying value, and, therefore, no impairment charge was recorded.

Intangible assets with discrete useful lives are amortized over their estimated useful lives. The Company has reassessed the useful lives of its identifiable intangible assets and determined that the remaining lives were appropriate.

Long-Lived Assets. The carrying value of long-lived assets, such as property, plant and equipment, and definite-lived intangible assets is reviewed when impairment indicators exist as required under generally accepted accounting principles. We consider many factors, including short- and long-term projections of future performance associated with these assets. If this review indicates that the long-lived assets will not be recoverable, the carrying value of such assets will be reduced to estimated fair value.

Self-Insurance. The Company obtains commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, architect's and engineer's errors and omissions risk, and other miscellaneous coverages. However, a reasonable amount of risk is retained on a self-insured basis primarily through a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism). Reserve requirements are established based on actuarial projections of ultimate losses. Losses estimated to be paid within 12 months are classified as accrued self-insurance reserves, while losses expected to be payable in later periods are included in long-term self-insurance reserves. Additionally, we maintain a self-insurance reserve for our health insurance programs maintained for the benefit of our eligible employees. We estimate a reserve based on historical levels of amounts incurred but not reported, which is included in accrued self-insurance reserves.

Environmental Liability. In accordance with accounting standards, we recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated. The cost of the clean-up is estimated by engineering,

39

financial and legal specialists based on current 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. As part of the acquisition of Tubelite Inc. in fiscal 2008, the Company acquired property which contains historical environmental conditions that the Company intends to remediate. At February 28, 2015, the reserve was $1.8 million. The reserve for environmental liabilities is included in other current and non-current liabilities in the consolidated balance sheets.

Foreign Currency. For foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated at the period-end exchange rates and income statement accounts are translated using the average exchange rates prevailing during the year. Translation adjustments are reflected in accumulated other comprehensive loss in the consolidated balance sheets.

From time to time, the Company may enter into short duration foreign currency contracts to hedge foreign currency risks. There is no material foreign currency risk related to these contracts as they generally have an original maturity date of less than one year.

Revenue Recognition. Generally, our sales terms are “free on board” (FOB) shipping point or FOB destination for our product-type sales, and revenue is recognized when title has transferred. However, the Company's Architectural Services segment business enters into fixed-price contracts for full-service commercial building glass installation and renovation services, which are accounted for as construction-type 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. The contracts entered into clearly specify the enforceable rights of the parties, the consideration and the terms of settlement, and both parties can be expected to satisfy all obligations under the contract. Approximately 25 percent, 26 percent and 27 percent of our consolidated net sales in fiscal 2015, 2014 and 2013, respectively, were recorded on a percentage-of-completion basis. Under the methodology, the Company compares the total costs incurred to date to the total estimated costs for each contract, and records that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. Given our ability to make reasonable estimates of our total contract revenues and total contract costs, we believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of precision in measuring progress toward completion of the installation contracts. 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 when they have been approved by customers. 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 revenues. The costs incurred by the Company for shipping and handling are reported as cost of sales.

Research and Development. Research and development expenses are charged to operations as incurred, and were $6.5 million, $7.8 million and $6.8 million for fiscal 2015, 2014 and 2013, respectively. Of these amounts, $2.4 million, $2.1 million and $1.6 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 expenses are charged to operations as incurred and were $1.1 million in fiscal 2015, $1.2 million in fiscal 2014, and $1.4 million in fiscal 2013. They are included in selling, general and administrative expenses in the consolidated results of operations.

Income Taxes. The Company accounts for income taxes as prescribed by applicable accounting standards, which requires use of the asset and liability method. This method recognizes deferred tax assets and liabilities based upon the future tax consequences of temporary differences between financial and tax reporting. See Note 13 for additional information regarding income taxes.

Accounting Estimates. The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting period. Amounts subject to significant estimates and assumptions include, but are not limited to, assessment of recoverability of long-lived assets, including goodwill, insurance reserves, warranty reserves,

40

net sales recognition for construction contracts, income tax provisions and liabilities; and the status of outstanding disputes and claims. Actual results could differ from those estimates.

New Accounting Standards.In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11 (ASU 2013-11), Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, as a reduction to a deferred tax asset in the financial statements for a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists with certain exceptions. The Company elected to prospectively adopt ASU 2013-11 in the first quarter of fiscal 2015. The Company's adoption of ASU 2013-11 resulted in a $0.5 million reclassification from unrecognized tax benefits to deferred tax liabilities in the consolidated balance sheets.

In May 2014, the FASB issued a standard on revenue from contracts with customers. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that 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, 2016, Apogee's fiscal 2018. The Company is currently evaluating the impact that this new standard will have on its consolidated financial statements. 

No other new accounting pronouncements issued or effective during fiscal 2015 have had or are expected to have a material impact on the consolidated financial statements.

Subsequent Events. In connection with preparing the audited consolidated financial statements for the year ended February 28, 2015, 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.

4. Marketable Securities

At February 28, 2015, the Company has investments in municipal bonds of $11.0 million; $0.3 million is current and $10.7 million is non-current. The Company’s wholly owned insurance subsidiary, Prism Assurance, Ltd., held all of the municipal bonds at the end of both fiscal 2015 and 2014. Prism insures a portion of the Company’s workers’ compensation, general liability 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 bonds, for the purpose of providing collateral for Prism’s obligations under the reinsurance agreement. All of the Company’s fixed maturity investments are classified as “available-for-sale,” are carried at fair value and are reported as short-term marketable securities available for sale or marketable securities available for sale in the consolidated balance sheets.

The amortized cost, gross unrealized gains and losses, and estimated fair values of investments available for sale at February 28, 2015 and March 1, 2014, are as follows:

(In thousands)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Estimated Fair Value
February 28, 2015
Municipal bonds	$	10,973	$	127	$	(118	)	$	10,982
Total investments	$	10,973	$	127	$	(118	)	$	10,982
March 1, 2014
Municipal bonds	$	11,719	$	94	$	(336	)	$	11,477
Total investments	$	11,719	$	94	$	(336	)	$	11,477

The Company tests for other than temporary losses on a quarterly basis and considers the unrealized losses indicated above to be temporary in nature. The Company intends to hold the investments until it can recover the full principal amount and has the ability to do so based on other sources of liquidity. The Company expects such recoveries to occur prior to the contractual maturities.

The following table presents the length of time that available-for-sale securities were in continuous unrealized loss positions, but were not deemed to be other than temporarily impaired, as of February 28, 2015:

	Less Than 12 Months					Greater Than or Equal  to 12 Months					Total
(In thousands)	Fair Value		Unrealized Losses			Fair Value		Unrealized Losses			Fair Value		Unrealized Losses
Municipal bonds	$	2,229	$	(7	)	$	1,139	$	(111	)	$	3,368	$	(118	)
Total investments	$	2,229	$	(7	)	$	1,139	$	(111	)	$	3,368	$	(118	)

The amortized cost and estimated fair values of investments at February 28, 2015, 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 call or prepayment penalties.

(In thousands)	Amortized Cost		Estimated Market Value
Due within one year	$	322	$	327
Due after one year through five years	2,835		2,848
Due after five years through 10 years	6,566		6,668
Due after 10 years through 15 years	1,250		1,139
Total	$	10,973	$	10,982

Gross realized gains were $0.1 million in fiscal 2015, were not material in fiscal 2014, and were $0.3 million in fiscal 2013. Gross realized losses were not material during fiscal 2015, 2014 or 2013. The gross realized gains and losses are included in other income (expense), net in the accompanying consolidated results of operations.

5. Fair Value Measurements

The Company accounts for financial assets and liabilities in accordance with accounting standards that define fair value and establish a framework for measuring fair value. The hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company does not have any Level 3 assets or liabilities.

Financial assets and liabilities measured at fair value as of February 28, 2015 and March 1, 2014, are summarized below:

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

Cash equivalents

Cash equivalents include highly liquid investments with an original maturity of three months or less, and consist primarily of money market funds. The cash equivalents are held at fair value based on quoted market prices, which approximates stated cost.

Available for sale securities

The Company has short-term available-for-sale securities of $0.3 million and long-term available-for-sale securities of $10.7 million as of February 28, 2015, consisting of municipal bonds. All of the Company’s fixed maturity investments are classified as “available-for-sale,” and are carried at fair market value based on prices from recent trades of similar securities.

Restricted investments

At March 1, 2014, the Company had long-term restricted investments consisting of money market funds, which were short-term in nature but were restricted for investment in the Company’s storefront and entrance business in Michigan, and were, therefore, classified as long term. The restricted investments were held at fair value based on quoted market prices, which approximated stated cost.

Mutual fund investments

The Company has $0.3 million of mutual fund investments as a long-term funding source for the deferred compensation plan. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

Foreign Currency Instruments

At March 1, 2014, the Company had a foreign exchange forward contract in place to hedge against the effect of exchange rate fluctuations on certain forecasted purchases. The forward contract was measured at fair value using readily observable market inputs, such as quotations on forward foreign exchange points and foreign interest rates.

6. Acquisitions

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited, a privately held business, for $52.9 million, including cash acquired of $1.6 million. Alumicor is a window, storefront, entrance and curtainwall company primarily serving the Canadian commercial construction market. Alumicor's results of operations are included within the Architectural Framing Systems segment.

The assets and liabilities of Alumicor were recorded in the consolidated balance sheet within the Architectural Framing Systems segment as of the acquisition date, at their respective fair values. The purchase price allocation was based on the estimated fair value of assets acquired and liabilities assumed and were allocated as follows:

(In thousands)	November 5, 2013
Current assets	$	17,168
Property, plant and equipment	9,773
Intangible assets	16,611
Goodwill	18,254
Current liabilities	(10,505		)
Net assets acquired	$	51,301

Identifiable intangible assets include customer relationships, which are definite-lived assets, and trademarks, which are indefinite-lived assets. The customer relationships have an amortization period of 19 years, which matches the average useful life of the asset. Goodwill recorded as part of the purchase price allocation is not tax deductible. 

45

The following unaudited pro forma consolidated condensed financial results of operations for the year ended March 1, 2014 and March 2, 2013 are presented as if the acquisition had been completed at the beginning of fiscal year 2013:

	Pro Forma
(In thousands, except per share data)	2014		2013
Net sales	$	825,596	$	756,497
Net income	30,487		21,064
Earnings per share
Basic	$	1.07	$	0.75
Diluted	1.04		0.74

These unaudited pro forma consolidated condensed financial results have been prepared for comparative purposes only and include certain adjustments, such as elimination of interest expense on pre-acquisition debt of the acquiree. The adjustments do not reflect the effect of synergies and integration costs that would result from integration of this acquisition.

7. Goodwill and Other Identifiable Intangible Assets

The changes in the carrying amount of goodwill attributable to each reporting segment for the year ended February 28, 2015 and March 1, 2014 is detailed below.

8. Debt

During the fourth quarter of fiscal 2015, we entered into an amendment of the Company's existing $100.0 million committed revolving credit facility. The amount of the facility was increased to $125.0 million, the expiration date was extended to December 2019; the letter of credit facility was reduced to $40.0 million from $50.0 million, the outstanding amounts of which decrease the available commitment; and the maximum debt-to-EBITDA ratio was increased to 3.00. No other provisions of the original agreement were materially amended by the amended credit agreement. No borrowings were outstanding under the facility as of February 28, 2015 or March 1, 2014. Letters of credit issued under the facility decrease the amount of available commitment; $101.5 million was available under the facility at February 28, 2015 and $76.5 million was available at March 1, 2014.

The credit facility requires the Company to maintain a debt-to-EBITDA ratio of not more than 3.00. This ratio is computed quarterly, with EBITDA computed on a rolling four-quarter basis. The Company’s ratio was 0.22 at February 28, 2015. The credit facility also requires the Company to maintain a minimum level of net worth, as defined in the credit facility, based on certain quarterly financial calculations. The minimum required net worth computed in accordance with the credit facility at February 28, 2015 was $318.8 million, whereas the Company’s net worth as defined in the credit facility was $382.5 million. If the Company is not in compliance with either of these covenants, the lenders may terminate the commitment and/or declare any loan then outstanding to be immediately due and payable. At February 28, 2015, the Company was in compliance with the financial covenants of the credit facility.

In the second quarter of fiscal 2015, the Company entered into a Canadian Dollar $4.0 million revolving demand facility available to our Canadian operation. Borrowings under the facility are made available at the sole discretion of the lender and are payable on demand. Borrowings under the facility bear interest at rates specified in the credit agreement for the facility. Outstanding balances under this demand facility are classified as long-term debt, since outstanding amounts can be refinanced through our committed revolving credit facility. No borrowings were outstanding as of February 28, 2015.

Included in the totals above are $20.4 million of industrial revenue bonds, and $0.2 million of other debt. The industrial revenue bonds mature in fiscal years 2021 through 2043, and the other debt matures in fiscal years 2016 through 2021. The fair value of the industrial revenue bonds approximates carrying value at February 28, 2015, due to the variable interest rates on these instruments. The bonds are classified as level 2 within the fair value hierarchy.

10. 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 their eligible earnings to this 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 $4.7 million in fiscal 2015, $4.2 million in fiscal 2014 and $3.6 million in fiscal 2013.

Deferred Compensation Plan

The Company maintains a deferred compensation plan that allows participants to defer compensation and save for retirement and other short-term needs. The deferred compensation liability was $4.2 million and $3.4 million at February 28, 2015 and March 1, 2014, respectively, and is included in other current and non-current liabilities in the consolidated balance sheet. The Company has investments in corporate-owned life insurance policies (COLI) of $4.0 million and mutual funds of $0.3 million with the intention of utilizing them as a long-term funding source for the deferred compensation 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. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

Plans under Collective Bargaining Agreements

The Company contributes to various multi-employer union retirement plans, which provide retirement benefits to the majority of its union employees; none of the plans are considered significant. The total contribution to these plans in fiscal 2015, 2014 and 2013 was $4.3 million, $3.7 million and $4.8 million, respectively.

Pension Plan

The Company sponsors the Tubelite, Inc. Hourly Employees' Pension Plan (Tubelite plan). This plan is a defined-benefit pension plan that was frozen to new entrants, with no additional years of service credit for participating employees as of January 1, 2004.

Officers' Supplemental Executive Retirement Plan (SERP)

The Company sponsors an unfunded SERP for the benefit of certain executives. The plan is considered a defined-benefit pension plan which is based principally on an employee's years of service and compensation levels near retirement. The SERP is frozen to new entrants and no additional benefits accrue for plan participants.

Obligations and Funded Status of Defined-Benefit Pensions 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. Both the Tubelite plan and the SERP use a fiscal year-end measurement date.

Additional Information

Assumptions

Weighted-average assumptions used at the measurement date to determine the defined-benefit plans' benefit obligation for the following fiscal years are as follows:

(Percentages)	2015		2014		2013
Discount rate	3.60	%	4.00	%	3.75	%

Weighted-average assumptions used at the measurement date to determine the defined-benefit plans' net periodic benefit cost for the following fiscal years are as follows:

(Percentages)	2015		2014		2013
Discount rate	4.00	%	3.75	%	4.00	%
Expected return on assets	4.50	%	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. This produced a discount rate of 3.60 percent. There are no known or anticipated changes in the discount rate assumption that will impact the pension expense in fiscal year 2016.

Expected return on assets. To develop the expected long-term rate of return on asset assumption, the Company considered historical long-term rates of return for broad asset classes, actual past rates of return achieved by the plan, the general mix of assets held by the plan and the stated investment policy for the plan. This resulted in the selection of the 4.50 percent long-term rate of return on assets assumption.

Net periodic benefit cost. Total net periodic pension benefit cost was $0.6 million in fiscal 2015, $0.5 million in fiscal 2014 and $0.6 million in fiscal 2013. Total net periodic pension benefit cost is expected to be approximately $0.7 million in fiscal 2016. The net periodic pension benefit cost for fiscal 2016 has been estimated assuming a discount rate of 3.60 percent.

Contributions

Pension contributions to the plans for fiscal 2015 and 2014 totaled $0.9 million and $0.8 million, respectively. Because the SERP is unfunded, contributions to that plan represent benefit payments made. The pension contributions in fiscal 2015 and 2014 equaled or exceeded the minimum funding requirement. Fiscal 2016 pension contributions are expected to total $1.0 million.

50

Estimated Future Benefit Payments

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

(In thousands)
Fiscal 2016	$	1,028
Fiscal 2017	1,027
Fiscal 2018	1,016
Fiscal 2019	1,043
Fiscal 2020	1,030
Fiscal 2021-2025	4,860

Plan Assets

The Company does not maintain assets intended for the future use of the SERP. In accordance with its policy, the assets of the Tubelite plan have been invested in a bond fund, the assets are carried at fair value based on prices from recent trades of similar securities, and are classified as Level 2 in the valuation hierarchy.

Employee Stock Purchase Plan

The Company also sponsors an employee stock purchase plan into which its 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 Company match 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 2015, 2014 and 2013.

11. Shareholders' Equity

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

Share Repurchases

During fiscal 2004, the Board of Directors authorized a share repurchase program of 1,500,000 shares of common stock. The Board of Directors increased this authorization by 750,000 shares in January 2008 and by 1,000,000 in October 2008. The Company purchased 203,509 shares under the program during fiscal 2015, for a total cost of $6.9 million. There were no share repurchases during fiscal 2014 or 2013. The Company has purchased a total of 2,482,632 shares, at a total cost of $36.5 million, since the inception of this program and has remaining authority to repurchase 767,368 shares under this program, which has no expiration date.

In addition to the shares repurchased according to this repurchase plan, during fiscal 2015, 2014 and 2013 the Company also purchased $5.2 million, $3.6 million and $1.5 million, respectively, of Company stock from employees in order to satisfy stock-for-stock option exercises or withholding tax obligations related to stock-based compensation, pursuant to terms of board and shareholder approved compensation plans.

12. Share-Based Compensation

The 2009 Stock Incentive Plan, the 2009 Non-Employee Director Stock Incentive Plan and the 2002 Omnibus Stock Incentive Plan (the Plans) provide for the issuance of 1,888,000, 250,000 and 3,400,000 shares, respectively, for various forms of stock-based compensation to employees and non-employee directors. Awards under these Plans, either in the form of incentive stock options, nonstatutory options or stock-settled stock appreciation rights (SARs), are granted with an exercise price equal to the fair market value of the Company’s stock at the date of award. Nonvested share awards and nonvested share unit awards are also included in these Plans. Outstanding SARs vested over a three-year period and outstanding options issued to non-employee directors vested at the end of six months. Outstanding options and SARs have a 10-year term. Nonvested share awards and nonvested share unit awards generally vest over a two, three or four-year period.

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

Total stock-based compensation expense under all Plans included in the results of operations was $4.8 million for fiscal 2015, $4.7 million for fiscal 2014 and $4.4 million for 2013.

Stock Options and SARs

There were no options or SARs issued in fiscal 2015, 2014 or 2013.

The following table summarizes the award transactions under the Plans for the year ended February 28, 2015:

	Options/SARs Outstanding
	Number of Shares		Weighted Average Exercise  Price		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value

Awards exercised	(223,257	)	19.38
Awards canceled	(500	)	11.86
Outstanding and exercisable at February 28, 2015	624,095		$	11.92	5.3 Years	$	21,178,150

Cash proceeds from the exercise of stock options were $1.2 million, $4.2 million and $2.3 million for fiscal 2015, 2014 and 2013, respectively. The aggregate intrinsic value of securities (the amount by which the stock price on the date of exercise exceeded the stock price of the award on the date of grant) exercised was $4.6 million in fiscal 2015, $6.2 million in fiscal 2014 and $2.5 million in fiscal 2013. The tax benefit realized for tax deductions from option exercises totaled $3.3 million, $2.6 million and $0.4 million for fiscal 2015, 2014 and 2013, respectively.

Nonvested Shares and Share Units

The Company's executive compensation program provides key employees selected by the Compensation Committee of the Board of Directors with long-term incentives using nonvested shares and nonvested share units. During fiscal 2015, 2014 and 2013, nonvested shares were issued based on performance against objectives and generally vest over three years. From fiscal 2010 through fiscal 2012, nonvested share units were issued at the beginning of each fiscal year, which gave the recipient the right to receive shares earned at the vesting date. The number of nonvested share units issued at grant was equal to the target number of nonvested share units and allowed for the right to receive an additional number of, or fewer, shares based on meeting pre-determined Company three-year performance goals.

At February 28, 2015, there was $5.2 million of total unrecognized compensation cost related to nonvested share and nonvested share unit awards, which is expected to be recognized over a weighted average period of approximately 22 months. The total fair value of shares vested during fiscal 2015 was $11.6 million.

The Company recognized approximately $6.4 million of tax benefit from an energy-efficiency 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 United States.

In fiscal 2015, 2014 and 2013, there were tax benefits associated with stock-based incentive plans of $3.3 million, $2.6 million and $0.4 million, respectively. These benefits impacted additional paid-in capital directly and were not reflected in the determination of income tax expense or benefit.

The Company has state net operating loss carryforwards with a tax effect of $3.6 million. A valuation allowance of $2.6 million has been established for these net operating loss carryforwards due to the uncertainty of the use of the tax benefits in future periods.

The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, Canada, Brazil and other international jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years prior to fiscal 2012, or state and local income tax examinations for years prior to fiscal 2008. The Company is not currently under U.S. federal examination

54

for years subsequent to fiscal year 2011, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions.

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

The total liability for unrecognized tax benefits for fiscal 2015, 2014 and 2013, respectively, is $5.0 million, $5.2 million and $6.8 million. Included in this total liability for each of fiscal 2015 and 2014 are $2.6 million and $3.3 million for fiscal 2013, of tax benefits that, if recognized, would decrease the effective tax rate. Also included in the balance of unrecognized tax benefits for fiscal 2015, 2014 and 2013 are $1.9 million, $1.8 million and $2.2 million 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, which is consistent with past practices. Related to the unrecognized tax benefits noted above, the Company reduced the accrual for penalties and interest by $0.3 million during fiscal 2015, resulting in a reserve for interest and penalties of $0.5 million at the end of fiscal 2015. During fiscal 2014, the Company reduced the accrual for penalties and interest by $0.5 million, resulting in a reserve for interest and penalties at the end of fiscal 2014 of $0.8 million. During fiscal 2013, the Company reduced the accrual for penalties and interest by $0.5 million, resulting in a reserve for interest and penalties at the end of fiscal 2013 of $1.3 million.

A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows:

(In thousands)	2015			2014			2013
Gross unrecognized tax benefits at beginning of year	$	4,431		$	5,516		$	7,125

Unrecognized tax benefits acquired in connection with Alumicor	—			94			—
Gross unrecognized tax benefits at end of year	$	4,491		$	4,431		$	5,516

The total liability for unrecognized tax benefits is expected to decrease by approximately $0.7 million during fiscal 2016 due to audit settlements and lapsing of statutes.

In September 2013, the U.S. Department of the Treasury and the IRS issued final regulations addressing the acquisition, production and improvement of tangible property, and also proposed regulations addressing the disposition of property. These regulations replace previously issued temporary regulations and are effective for tax years beginning on or after January 1, 2014. The adoption of the new regulations did not have a material impact on the Company’s consolidated financial statements.

15. Earnings per Share

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

(In thousands)	2015	2014	2013

16.Business Segment Data

The Company has four reporting segments: Architectural Glass, Architectural Services, Architectural Framing Systems and Large-Scale Optical (LSO). The Architectural Glass segment fabricates glass used in customized window and wall systems comprising the outside skin of commercial and institutional buildings. The Architectural Services segment designs, engineers, fabricates and installs the walls of glass, and windows and other curtainwall products making up the outside skin of commercial and institutional buildings for new construction and renovation. 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 and institutional buildings. The Company has aggregated four operating segments into the Architectural Framing Systems reporting segment based upon their similar products, customers, distribution methods, production processes and economic characteristics. The LSO segment manufactures value-added glass and acrylic products for the custom picture framing market.

(1) During the fourth quarter of fiscal 2015, the Company changed its method of accounting for those inventories which were accounted for under the LIFO method to the FIFO method. See Note 1 for discussion of this accounting change and its related impact.

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

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

(In thousands)	2015		2014		2013
Net Sales
United States	$	847,887	$	718,881	$	668,243
Canada	50,807		15,850		—

Apogee's export net sales from U.S. operations of $72.7 million for fiscal 2015 were approximately 8 percent of consolidated net sales; export net sales of $52.5 million for fiscal 2014 were approximately 7 percent of consolidated net sales; and export sales of $63.5 million for fiscal 2013 were approximately 9 percent of consolidated net sales. All sales from Canada and Brazil were to customers outside the United States, and are subject to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. No single customer, including government agencies, accounts for 10 percent or more of consolidated net sales.

Segment operating income is equal to net sales less cost of sales and operating expenses. Operating income does not include provision for interest expense or income taxes. Corporate and other includes miscellaneous corporate activity not allocable to business segments.

Included in the identifiable assets for Corporate and other are the short- and long-term available-for-sale securities at Prism of $11.0 million in fiscal 2015 and $11.5 million in fiscal 2014. Also included are short- and long-term restricted investments at corporate of $2.5 million in fiscal 2014.

17. Commitments and Contingent Liabilities

Operating lease commitments. As of February 28, 2015, the Company was obligated under noncancelable operating leases for buildings and equipment. Certain leases provide for increased rentals based upon increases in real estate taxes or operating costs. Future minimum rental payments under noncancelable operating leases are:

(In thousands)	Fiscal 2016		Fiscal 2017		Fiscal 2018		Fiscal 2019		Fiscal 2020		Thereafter		Total
Total minimum payments	$	9,341	$	7,423	$	6,609	$	5,932	$	4,675	$	3,658	$	37,638

Total rental expense, including operating leases and short-term equipment rentals, was $18.7 million, $15.4 million and $13.0 million in fiscal 2015, 2014 and 2013, respectively.

At February 28, 2015, the Company 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 $2.8 million under the sale and leaseback transaction, which is included in the balance sheet caption as other current and non-current liabilities. The average annual lease payment over the life of the remaining lease is $1.0 million.

Bond commitments. In the ordinary course of business, predominantly in the Company’s Architectural Services business, the Company is required to provide surety or performance bonds that commit payments to its customers for any non-performance by the Company. At February 28, 2015, $76.9 million of the Company’s backlog was bonded by performance bonds with a face value of $274.0 million. Performance bonds do not have stated expiration dates, as the Company is released from the bonds upon

58

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 the current portfolio of businesses.

Guarantees and warranties. The Company accrues 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. The Company’s warranty and claim accruals are detailed below.

(In thousands)	2015			2014
Balance at beginning of period	$	11,978		$	8,323
Additional accruals	6,482			6,680
Claims paid	(7,185		)	(3,025		)
Balance at end of period	$	11,275		$	11,978

Letters of credit. At February 28, 2015, the Company had ongoing letters of credit related to its construction contracts and certain industrial revenue bonds. The total value of letters of credit under which the Company was obligated as of February 28, 2015 was approximately $23.5 million, all of which have been issued under the credit facility. The Company’s total availability under its $125.0 million credit facility is reduced by borrowings under the facility and also by letters of credit issued under the facility.

Purchase obligations. The Company has purchase obligations for raw material commitments and capital expenditures. As of February 28, 2015, these obligations totaled $158.9 million.

New Markets Tax Credit transaction. On November 7, 2013, the Company entered into a transaction with JP Morgan Chase (JPM) related to an investment in plant and equipment within the Company’s Architectural Glass segment (the Project) whereby the Company received $7.8 million of cash from a qualified New Markets Tax Credit program (NMTC). The NMTC was provided for in the Community Renewal Tax Relief Act of 2000 and is intended to induce investment in underserved and impoverished areas of the United States. The Act permits taxpayers, whether companies or individuals, to claim credits against their federal income taxes for up to 39 percent of investments in qualified, active low-income businesses or ventures.

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 Company has concluded that the entities created in relation to the NMTC transaction are consolidated as variable-interest entities.

Based on the contractual arrangements that obligate the Company to deliver tax benefits to JPM, the Company has included the value of JPM’s contribution in other non-current liabilities within the 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 the Company’s 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 employment practices, workers compensation, general liability 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.

Dear Sirs/Madams:

We have audited the consolidated financial statements of Apogee Enterprises, Inc. as of February 28, 2015 and March 1, 2014 and for each of the three years in the period ended February 28, 2015, included in your Annual Report on Form 10-K to the Securities and Exchange Commission and have issued our report thereon dated April 29, 2015, which expresses an unqualified opinion. Note 1 to such consolidated financial statements contains a description of your adoption during the year ended February 28, 2015 of the change in accounting method of valuing all inventories that used the last-in, first-out (LIFO) method to the first-in, first-out (FIFO) method. In our judgment, such change is to an alternative accounting principle that is preferable under the circumstances.

Yours truly,

Segment Reporting [Abstract]

Business Segment Data

Business Segment Data

The Company has four reporting segments: Architectural Glass, Architectural Services, Architectural Framing Systems and Large-Scale Optical (LSO). The Architectural Glass segment fabricates glass used in customized window and wall systems comprising the outside skin of commercial and institutional buildings. The Architectural Services segment designs, engineers, fabricates and installs the walls of glass, and windows and other curtainwall products making up the outside skin of commercial and institutional buildings for new construction and renovation. 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 and institutional buildings. The Company has aggregated four operating segments into the Architectural Framing Systems reporting segment based upon their similar products, customers, distribution methods, production processes and economic characteristics. The LSO segment manufactures value-added glass and acrylic products for the custom picture framing market.

The following table presents certain data for the Company's four reporting segments, and consolidated data, for fiscal 2015, 2014 and 2013.

(1) During the fourth quarter of fiscal 2015, the Company changed its method of accounting for those inventories which were accounted for under the LIFO method to the FIFO method. See Note 1 for discussion of this accounting change and its related impact.

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

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

(In thousands)	2015		2014		2013
Net Sales
United States	$	847,887	$	718,881	$	668,243
Canada	50,807		15,850		—
Brazil	35,242		36,714		31,981

Brazil	7,278		7,537		8,611
Total	$	193,540	$	193,946	$	168,948

Apogee's export net sales from U.S. operations of $72.7 million for fiscal 2015 were approximately 8 percent of consolidated net sales; export net sales of $52.5 million for fiscal 2014 were approximately 7 percent of consolidated net sales; and export sales of $63.5 million for fiscal 2013 were approximately 9 percent of consolidated net sales. All sales from Canada and Brazil were to customers outside the United States, and are subject to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. No single customer, including government agencies, accounts for 10 percent or more of consolidated net sales.

Segment operating income is equal to net sales less cost of sales and operating expenses. Operating income does not include provision for interest expense or income taxes. Corporate and other includes miscellaneous corporate activity not allocable to business segments.

Included in the identifiable assets for Corporate and other are the short- and long-term available-for-sale securities at Prism of $11.0 million in fiscal 2015 and $11.5 million in fiscal 2014. Also included are short- and long-term restricted investments at corporate of $2.5 million in fiscal 2014.

Summary of Significant Accounting Policies and Related Data (Policies)

12 Months Ended

Feb. 28, 2015

Accounting Policies [Abstract]

Basis of Consolidation

Basis of Consolidation. The accompanying consolidated financial statements include the accounts of Apogee Enterprises, Inc., a Minnesota corporation, and all majority-owned subsidiaries (the Company). Transactions between Apogee and its subsidiaries have been eliminated in consolidation.

The results of Alumicor Limited (Alumicor), which the Company acquired on November 5, 2013, are included in the Company's Architectural Framing Systems segment. Refer to Note 6 for further information regarding the acquisition of Alumicor and its treatment in the consolidated financial statements.

GlassecViracon's fiscal year ends December 31 and its results are incorporated into the consolidated financial statements on a two-month lag. There were no significant intervening events that would have materially affected our consolidated financial statements had they been recorded during the year ended February 28, 2015.

Fiscal Year

Fiscal Year. Apogee's fiscal year ends on the Saturday closest to the last day of February. Fiscal 2015, 2014 and 2013 each consisted of 52 weeks.

Financial Instruments

Financial Instruments. Unless otherwise noted, the carrying amount of the Company's financial instruments approximates fair value.

Cash and Cash Equivalents

Cash and Cash Equivalents. Investments with an original maturity of three months or less are included in cash and cash equivalents. Cash equivalents are stated at cost, which approximates fair value, and consist primarily of money market funds.

Investments

Investments. The Company has marketable securities consisting of high-quality municipal bonds. The securities are classified as “available for sale” and are carried at fair value based on prices from recent trades of similar securities. The Company tests for other than temporary losses on a quarterly basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If a decline in the fair value of a security is deemed by management to be other-than-temporary, the investment is written down to fair value, and the amount of the write-down is included in net earnings.

The Company also has investments in mutual funds as a long-term funding source for the deferred compensation plan. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

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.

During the fourth quarter of fiscal 2015, the Company changed its method of accounting for those inventories which were accounted for under the last-in, first-out (“LIFO”) method (53 percent of total fiscal 2014 inventories) to the FIFO method. The Company believes that this change is preferable as it provides uniformity across the Company's operations with respect to the method of inventory accounting, better reflects the current value of inventories on the consolidated balance sheets, aligns the accounting with the physical flow of inventory, and better matches revenues with associated expenses.

The change was applied retrospectively to March 3, 2012. The resulting impact to our consolidated balance sheets as of March 1, 2014 is as follows:

	March 1, 2014
(In thousands)	As Originally Reported		LIFO to FIFO Adjustment			Retrospectively Adjusted
Inventories, net	$	47,982	$	5,453		$	53,435
Current deferred tax assets	3,529		(815		)	2,714
Non-current deferred tax liabilities	7,403		1,164			8,567
Retained earnings	225,367		3,474			228,841

No retrospective adjustments were made to the consolidated results of operations or consolidated statements of cash flow as they were immaterial for all periods presented, resulting in an immaterial adjustment recorded to the consolidated results of operations and consolidated balance sheets during the fourth quarter of fiscal 2015 of approximately $0.1 million.

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 income as a reduction of or increase 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. The Company accounts for goodwill and intangible assets in accordance with applicable accounting standards.

The Company tests goodwill of each of its reporting units for impairment annually in connection with its fourth-quarter planning process or more frequently if impairment indicators exist. The Company has determined that each of its business units represents a reporting unit in accordance with applicable accounting standards. During the fourth quarter of fiscal 2015, the Company completed its annual impairment test using discounted cash flow methodologies for valuing its reporting units as no market comparables were identified. There have not been any material changes in the impairment loss assessment methodology made during the past three fiscal years. The estimates of fair value for the reporting units were found to be in excess of their carrying value, and, therefore, no impairment charge was recorded.

Intangible assets with discrete useful lives are amortized over their estimated useful lives. The Company has reassessed the useful lives of its identifiable intangible assets and determined that the remaining lives were appropriate.

Long-Lived Assets

Long-Lived Assets. The carrying value of long-lived assets, such as property, plant and equipment, and definite-lived intangible assets is reviewed when impairment indicators exist as required under generally accepted accounting principles. We consider many factors, including short- and long-term projections of future performance associated with these assets. If this review indicates that the long-lived assets will not be recoverable, the carrying value of such assets will be reduced to estimated fair value.

Self Insurance

Self-Insurance. The Company obtains commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, architect's and engineer's errors and omissions risk, and other miscellaneous coverages. However, a reasonable amount of risk is retained on a self-insured basis primarily through a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism). Reserve requirements are established based on actuarial projections of ultimate losses. Losses estimated to be paid within 12 months are classified as accrued self-insurance reserves, while losses expected to be payable in later periods are included in long-term self-insurance reserves. Additionally, we maintain a self-insurance reserve for our health insurance programs maintained for the benefit of our eligible employees. We estimate a reserve based on historical levels of amounts incurred but not reported, which is included in accrued self-insurance reserves.

Environmental Liability

Environmental Liability. In accordance with accounting standards, we recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated. The cost of the clean-up is estimated by engineering, financial and legal specialists based on current 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. As part of the acquisition of Tubelite Inc. in fiscal 2008, the Company acquired property which contains historical environmental conditions that the Company intends to remediate. At February 28, 2015, the reserve was $1.8 million. The reserve for environmental liabilities is included in other current and non-current liabilities in the consolidated balance sheets.

Foreign Currency

Foreign Currency. For foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated at the period-end exchange rates and income statement accounts are translated using the average exchange rates prevailing during the year. Translation adjustments are reflected in accumulated other comprehensive loss in the consolidated balance sheets.

From time to time, the Company may enter into short duration foreign currency contracts to hedge foreign currency risks. There is no material foreign currency risk related to these contracts as they generally have an original maturity date of less than one year.

Revenue Recognition

Revenue Recognition. Generally, our sales terms are “free on board” (FOB) shipping point or FOB destination for our product-type sales, and revenue is recognized when title has transferred. However, the Company's Architectural Services segment business enters into fixed-price contracts for full-service commercial building glass installation and renovation services, which are accounted for as construction-type 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. The contracts entered into clearly specify the enforceable rights of the parties, the consideration and the terms of settlement, and both parties can be expected to satisfy all obligations under the contract. Approximately 25 percent, 26 percent and 27 percent of our consolidated net sales in fiscal 2015, 2014 and 2013, respectively, were recorded on a percentage-of-completion basis. Under the methodology, the Company compares the total costs incurred to date to the total estimated costs for each contract, and records that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. Given our ability to make reasonable estimates of our total contract revenues and total contract costs, we believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of precision in measuring progress toward completion of the installation contracts. 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 when they have been approved by customers. 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 revenues. The costs incurred by the Company for shipping and handling are reported as cost of sales.

Research and Development

Research and Development. Research and development expenses are charged to operations as incurred, and were $6.5 million, $7.8 million and $6.8 million for fiscal 2015, 2014 and 2013, respectively. Of these amounts, $2.4 million, $2.1 million and $1.6 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 expenses are charged to operations as incurred and were $1.1 million in fiscal 2015, $1.2 million in fiscal 2014, and $1.4 million in fiscal 2013. They are included in selling, general and administrative expenses in the consolidated results of operations.

Income Taxes

Income Taxes. The Company accounts for income taxes as prescribed by applicable accounting standards, which requires use of the asset and liability method. This method recognizes deferred tax assets and liabilities based upon the future tax consequences of temporary differences between financial and tax reporting. See Note 13 for additional information regarding income taxes.

Accounting Estimates

Accounting Estimates. The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting period. Amounts subject to significant estimates and assumptions include, but are not limited to, assessment of recoverability of long-lived assets, including goodwill, insurance reserves, warranty reserves, net sales recognition for construction contracts, income tax provisions and liabilities; and the status of outstanding disputes and claims. Actual results could differ from those estimates.

New Accounting Standards

New Accounting Standards.In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11 (ASU 2013-11), Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, as a reduction to a deferred tax asset in the financial statements for a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists with certain exceptions. The Company elected to prospectively adopt ASU 2013-11 in the first quarter of fiscal 2015. The Company's adoption of ASU 2013-11 resulted in a $0.5 million reclassification from unrecognized tax benefits to deferred tax liabilities in the consolidated balance sheets.

In May 2014, the FASB issued a standard on revenue from contracts with customers. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that 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, 2016, Apogee's fiscal 2018. The Company is currently evaluating the impact that this new standard will have on its consolidated financial statements. 

No other new accounting pronouncements issued or effective during fiscal 2015 have had or are expected to have a material impact on the consolidated financial statements.

Subsequent Events

Subsequent Events. In connection with preparing the audited consolidated financial statements for the year ended February 28, 2015, 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 Company recognized approximately $6.4 million of tax benefit from an energy-efficiency 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 United States.

In fiscal 2015, 2014 and 2013, there were tax benefits associated with stock-based incentive plans of $3.3 million, $2.6 million and $0.4 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 28, 2015 and March 1, 2014 are as follows:

The Company has state net operating loss carryforwards with a tax effect of $3.6 million. A valuation allowance of $2.6 million has been established for these net operating loss carryforwards due to the uncertainty of the use of the tax benefits in future periods.

The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, Canada, Brazil and other international jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years prior to fiscal 2012, or state and local income tax examinations for years prior to fiscal 2008. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2011, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions.

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

The total liability for unrecognized tax benefits for fiscal 2015, 2014 and 2013, respectively, is $5.0 million, $5.2 million and $6.8 million. Included in this total liability for each of fiscal 2015 and 2014 are $2.6 million and $3.3 million for fiscal 2013, of tax benefits that, if recognized, would decrease the effective tax rate. Also included in the balance of unrecognized tax benefits for fiscal 2015, 2014 and 2013 are $1.9 million, $1.8 million and $2.2 million 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, which is consistent with past practices. Related to the unrecognized tax benefits noted above, the Company reduced the accrual for penalties and interest by $0.3 million during fiscal 2015, resulting in a reserve for interest and penalties of $0.5 million at the end of fiscal 2015. During fiscal 2014, the Company reduced the accrual for penalties and interest by $0.5 million, resulting in a reserve for interest and penalties at the end of fiscal 2014 of $0.8 million. During fiscal 2013, the Company reduced the accrual for penalties and interest by $0.5 million, resulting in a reserve for interest and penalties at the end of fiscal 2013 of $1.3 million.

A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows:

(In thousands)	2015			2014			2013
Gross unrecognized tax benefits at beginning of year	$	4,431		$	5,516		$	7,125
Gross increases in tax positions for prior years	261			44			236
Gross decreases in tax positions for prior years	(276		)	(616		)	(1,480		)

Unrecognized tax benefits acquired in connection with Alumicor	—			94			—
Gross unrecognized tax benefits at end of year	$	4,491		$	4,431		$	5,516

The total liability for unrecognized tax benefits is expected to decrease by approximately $0.7 million during fiscal 2016 due to audit settlements and lapsing of statutes.

In September 2013, the U.S. Department of the Treasury and the IRS issued final regulations addressing the acquisition, production and improvement of tangible property, and also proposed regulations addressing the disposition of property. These regulations replace previously issued temporary regulations and are effective for tax years beginning on or after January 1, 2014. The adoption of the new regulations did not have a material impact on the Company’s consolidated financial statements.

Earnings per Share

Basic earnings per share is computed by dividing net income or loss by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net income or loss by the weighted average common shares outstanding, including the dilutive effects of stock options, SARs and nonvested shares.

During the fourth quarter of fiscal 2015, we entered into an amendment of the Company's existing $100.0 million committed revolving credit facility. The amount of the facility was increased to $125.0 million, the expiration date was extended to December 2019; the letter of credit facility was reduced to $40.0 million from $50.0 million, the outstanding amounts of which decrease the available commitment; and the maximum debt-to-EBITDA ratio was increased to 3.00. No other provisions of the original agreement were materially amended by the amended credit agreement. No borrowings were outstanding under the facility as of February 28, 2015 or March 1, 2014. Letters of credit issued under the facility decrease the amount of available commitment; $101.5 million was available under the facility at February 28, 2015 and $76.5 million was available at March 1, 2014.

The credit facility requires the Company to maintain a debt-to-EBITDA ratio of not more than 3.00. This ratio is computed quarterly, with EBITDA computed on a rolling four-quarter basis. The Company’s ratio was 0.22 at February 28, 2015. The credit facility also requires the Company to maintain a minimum level of net worth, as defined in the credit facility, based on certain quarterly financial calculations. The minimum required net worth computed in accordance with the credit facility at February 28, 2015 was $318.8 million, whereas the Company’s net worth as defined in the credit facility was $382.5 million. If the Company is not in compliance with either of these covenants, the lenders may terminate the commitment and/or declare any loan then outstanding to be immediately due and payable. At February 28, 2015, the Company was in compliance with the financial covenants of the credit facility.

In the second quarter of fiscal 2015, the Company entered into a Canadian Dollar $4.0 million revolving demand facility available to our Canadian operation. Borrowings under the facility are made available at the sole discretion of the lender and are payable on demand. Borrowings under the facility bear interest at rates specified in the credit agreement for the facility. Outstanding balances under this demand facility are classified as long-term debt, since outstanding amounts can be refinanced through our committed revolving credit facility. No borrowings were outstanding as of February 28, 2015.

Included in the totals above are $20.4 million of industrial revenue bonds, and $0.2 million of other debt. The industrial revenue bonds mature in fiscal years 2021 through 2043, and the other debt matures in fiscal years 2016 through 2021. The fair value of the industrial revenue bonds approximates carrying value at February 28, 2015, due to the variable interest rates on these instruments. The bonds are classified as level 2 within the fair value hierarchy.

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 their eligible earnings to this 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 $4.7 million in fiscal 2015, $4.2 million in fiscal 2014 and $3.6 million in fiscal 2013.

Deferred Compensation Plan

The Company maintains a deferred compensation plan that allows participants to defer compensation and save for retirement and other short-term needs. The deferred compensation liability was $4.2 million and $3.4 million at February 28, 2015 and March 1, 2014, respectively, and is included in other current and non-current liabilities in the consolidated balance sheet. The Company has investments in corporate-owned life insurance policies (COLI) of $4.0 million and mutual funds of $0.3 million with the intention of utilizing them as a long-term funding source for the deferred compensation 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. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

Plans under Collective Bargaining Agreements

The Company contributes to various multi-employer union retirement plans, which provide retirement benefits to the majority of its union employees; none of the plans are considered significant. The total contribution to these plans in fiscal 2015, 2014 and 2013 was $4.3 million, $3.7 million and $4.8 million, respectively.

Pension Plan

The Company sponsors the Tubelite, Inc. Hourly Employees' Pension Plan (Tubelite plan). This plan is a defined-benefit pension plan that was frozen to new entrants, with no additional years of service credit for participating employees as of January 1, 2004.

Officers' Supplemental Executive Retirement Plan (SERP)

The Company sponsors an unfunded SERP for the benefit of certain executives. The plan is considered a defined-benefit pension plan which is based principally on an employee's years of service and compensation levels near retirement. The SERP is frozen to new entrants and no additional benefits accrue for plan participants.

Obligations and Funded Status of Defined-Benefit Pensions 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. Both the Tubelite plan and the SERP use a fiscal year-end measurement date.

(In thousands)	2015		2014
Net actuarial loss (gain)	$	1,458	$	(19	)
Total	$	1,458	$	(19	)

Amortization of unrecognized net loss	172			163			211
Net periodic benefit cost	$	551		$	518		$	604

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 2016 is $0.2 million, net of tax benefit.

Additional Information

Assumptions

Weighted-average assumptions used at the measurement date to determine the defined-benefit plans' benefit obligation for the following fiscal years are as follows:

(Percentages)	2015		2014		2013
Discount rate	3.60	%	4.00	%	3.75	%

Weighted-average assumptions used at the measurement date to determine the defined-benefit plans' net periodic benefit cost for the following fiscal years are as follows:

(Percentages)	2015		2014		2013
Discount rate	4.00	%	3.75	%	4.00	%
Expected return on assets	4.50	%	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. This produced a discount rate of 3.60 percent. There are no known or anticipated changes in the discount rate assumption that will impact the pension expense in fiscal year 2016.

Expected return on assets. To develop the expected long-term rate of return on asset assumption, the Company considered historical long-term rates of return for broad asset classes, actual past rates of return achieved by the plan, the general mix of assets held by the plan and the stated investment policy for the plan. This resulted in the selection of the 4.50 percent long-term rate of return on assets assumption.

Net periodic benefit cost. Total net periodic pension benefit cost was $0.6 million in fiscal 2015, $0.5 million in fiscal 2014 and $0.6 million in fiscal 2013. Total net periodic pension benefit cost is expected to be approximately $0.7 million in fiscal 2016. The net periodic pension benefit cost for fiscal 2016 has been estimated assuming a discount rate of 3.60 percent.

Contributions

Pension contributions to the plans for fiscal 2015 and 2014 totaled $0.9 million and $0.8 million, respectively. Because the SERP is unfunded, contributions to that plan represent benefit payments made. The pension contributions in fiscal 2015 and 2014 equaled or exceeded the minimum funding requirement. Fiscal 2016 pension contributions are expected to total $1.0 million.

Estimated Future Benefit Payments

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

(In thousands)
Fiscal 2016	$	1,028
Fiscal 2017	1,027
Fiscal 2018	1,016
Fiscal 2019	1,043
Fiscal 2020	1,030
Fiscal 2021-2025	4,860

Plan Assets

The Company does not maintain assets intended for the future use of the SERP. In accordance with its policy, the assets of the Tubelite plan have been invested in a bond fund, the assets are carried at fair value based on prices from recent trades of similar securities, and are classified as Level 2 in the valuation hierarchy.

Employee Stock Purchase Plan

The Company also sponsors an employee stock purchase plan into which its 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 Company match 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 2015, 2014 and 2013.

Marketable Securities

Marketable Securities

At February 28, 2015, the Company has investments in municipal bonds of $11.0 million; $0.3 million is current and $10.7 million is non-current. The Company’s wholly owned insurance subsidiary, Prism Assurance, Ltd., held all of the municipal bonds at the end of both fiscal 2015 and 2014. Prism insures a portion of the Company’s workers’ compensation, general liability 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 bonds, for the purpose of providing collateral for Prism’s obligations under the reinsurance agreement. All of the Company’s fixed maturity investments are classified as “available-for-sale,” are carried at fair value and are reported as short-term marketable securities available for sale or marketable securities available for sale in the consolidated balance sheets.

The amortized cost, gross unrealized gains and losses, and estimated fair values of investments available for sale at February 28, 2015 and March 1, 2014, are as follows:

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

Total investments	$	11,719	$	94	$	(336	)	$	11,477

The Company tests for other than temporary losses on a quarterly basis and considers the unrealized losses indicated above to be temporary in nature. The Company intends to hold the investments until it can recover the full principal amount and has the ability to do so based on other sources of liquidity. The Company expects such recoveries to occur prior to the contractual maturities.

The following table presents the length of time that available-for-sale securities were in continuous unrealized loss positions, but were not deemed to be other than temporarily impaired, as of February 28, 2015:

	Less Than 12 Months					Greater Than or Equal  to 12 Months					Total

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company accounts for financial assets and liabilities in accordance with accounting standards that define fair value and establish a framework for measuring fair value. The hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company does not have any Level 3 assets or liabilities.

Financial assets and liabilities measured at fair value as of February 28, 2015 and March 1, 2014, are summarized below:

Cash equivalents

Cash equivalents include highly liquid investments with an original maturity of three months or less, and consist primarily of money market funds. The cash equivalents are held at fair value based on quoted market prices, which approximates stated cost.

Available for sale securities

The Company has short-term available-for-sale securities of $0.3 million and long-term available-for-sale securities of $10.7 million as of February 28, 2015, consisting of municipal bonds. All of the Company’s fixed maturity investments are classified as “available-for-sale,” and are carried at fair market value based on prices from recent trades of similar securities.

Restricted investments

At March 1, 2014, the Company had long-term restricted investments consisting of money market funds, which were short-term in nature but were restricted for investment in the Company’s storefront and entrance business in Michigan, and were, therefore, classified as long term. The restricted investments were held at fair value based on quoted market prices, which approximated stated cost.

Mutual fund investments

The Company has $0.3 million of mutual fund investments as a long-term funding source for the deferred compensation plan. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

Foreign Currency Instruments

At March 1, 2014, the Company had a foreign exchange forward contract in place to hedge against the effect of exchange rate fluctuations on certain forecasted purchases. The forward contract was measured at fair value using readily observable market inputs, such as quotations on forward foreign exchange points and foreign interest rates.

Stock-Based Compensation

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

Stock-Based Compensation

Share-Based Compensation

The 2009 Stock Incentive Plan, the 2009 Non-Employee Director Stock Incentive Plan and the 2002 Omnibus Stock Incentive Plan (the Plans) provide for the issuance of 1,888,000, 250,000 and 3,400,000 shares, respectively, for various forms of stock-based compensation to employees and non-employee directors. Awards under these Plans, either in the form of incentive stock options, nonstatutory options or stock-settled stock appreciation rights (SARs), are granted with an exercise price equal to the fair market value of the Company’s stock at the date of award. Nonvested share awards and nonvested share unit awards are also included in these Plans. Outstanding SARs vested over a three-year period and outstanding options issued to non-employee directors vested at the end of six months. Outstanding options and SARs have a 10-year term. Nonvested share awards and nonvested share unit awards generally vest over a two, three or four-year period.

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

Total stock-based compensation expense under all Plans included in the results of operations was $4.8 million for fiscal 2015, $4.7 million for fiscal 2014 and $4.4 million for 2013.

Stock Options and SARs

There were no options or SARs issued in fiscal 2015, 2014 or 2013.

The following table summarizes the award transactions under the Plans for the year ended February 28, 2015:

	Options/SARs Outstanding
	Number of Shares		Weighted Average Exercise  Price		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value
Outstanding at March 1, 2014	847,852		$	13.88
Awards exercised	(223,257	)	19.38
Awards canceled	(500	)	11.86
Outstanding and exercisable at February 28, 2015	624,095		$	11.92	5.3 Years	$	21,178,150

Cash proceeds from the exercise of stock options were $1.2 million, $4.2 million and $2.3 million for fiscal 2015, 2014 and 2013, respectively. The aggregate intrinsic value of securities (the amount by which the stock price on the date of exercise exceeded the stock price of the award on the date of grant) exercised was $4.6 million in fiscal 2015, $6.2 million in fiscal 2014 and $2.5 million in fiscal 2013. The tax benefit realized for tax deductions from option exercises totaled $3.3 million, $2.6 million and $0.4 million for fiscal 2015, 2014 and 2013, respectively.

Nonvested Shares and Share Units

The Company's executive compensation program provides key employees selected by the Compensation Committee of the Board of Directors with long-term incentives using nonvested shares and nonvested share units. During fiscal 2015, 2014 and 2013, nonvested shares were issued based on performance against objectives and generally vest over three years. From fiscal 2010 through fiscal 2012, nonvested share units were issued at the beginning of each fiscal year, which gave the recipient the right to receive shares earned at the vesting date. The number of nonvested share units issued at grant was equal to the target number of nonvested share units and allowed for the right to receive an additional number of, or fewer, shares based on meeting pre-determined Company three-year performance goals.

The following table summarizes the nonvested share award transactions, including nonvested share units, for fiscal 2015:

	Nonvested Shares and Units
	Number of Shares and Units		Weighted Average Grant Date Fair Value
Nonvested at March 1, 2014	575,064		$	16.89
Granted(1)	186,468		28.45
Vested	(358,651	)	15.43
Canceled	(2,173	)	32.72
Nonvested at February 28, 2015	400,708		$	23.49

(1) Includes 40,735 of shares granted and immediately vested for achievement above target for the fiscal 2012-2014 performance period. Nonvested share units of 117,765 (at target) were previously granted in fiscal 2012 for this performance period.

At February 28, 2015, there was $5.2 million of total unrecognized compensation cost related to nonvested share and nonvested share unit awards, which is expected to be recognized over a weighted average period of approximately 22 months. The total fair value of shares vested during fiscal 2015 was $11.6 million.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

Operating lease commitments. As of February 28, 2015, the Company was obligated under noncancelable operating leases for buildings and equipment. Certain leases provide for increased rentals based upon increases in real estate taxes or operating costs. Future minimum rental payments under noncancelable operating leases are:

(In thousands)	Fiscal 2016		Fiscal 2017		Fiscal 2018		Fiscal 2019		Fiscal 2020		Thereafter		Total
Total minimum payments	$	9,341	$	7,423	$	6,609	$	5,932	$	4,675	$	3,658	$	37,638

Total rental expense, including operating leases and short-term equipment rentals, was $18.7 million, $15.4 million and $13.0 million in fiscal 2015, 2014 and 2013, respectively.

At February 28, 2015, the Company 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 $2.8 million under the sale and leaseback transaction, which is included in the balance sheet caption as other current and non-current liabilities. The average annual lease payment over the life of the remaining lease is $1.0 million.

Bond commitments. In the ordinary course of business, predominantly in the Company’s Architectural Services business, the Company is required to provide surety or performance bonds that commit payments to its customers for any non-performance by the Company. At February 28, 2015, $76.9 million of the Company’s backlog was bonded by performance bonds with a face value of $274.0 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 the current portfolio of businesses.

Guarantees and warranties. The Company accrues 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. The Company’s warranty and claim accruals are detailed below.

(In thousands)	2015			2014
Balance at beginning of period	$	11,978		$	8,323
Additional accruals	6,482			6,680
Claims paid	(7,185		)	(3,025		)
Balance at end of period	$	11,275		$	11,978

Letters of credit. At February 28, 2015, the Company had ongoing letters of credit related to its construction contracts and certain industrial revenue bonds. The total value of letters of credit under which the Company was obligated as of February 28, 2015 was approximately $23.5 million, all of which have been issued under the credit facility. The Company’s total availability under its $125.0 million credit facility is reduced by borrowings under the facility and also by letters of credit issued under the facility.

Purchase obligations. The Company has purchase obligations for raw material commitments and capital expenditures. As of February 28, 2015, these obligations totaled $158.9 million.

New Markets Tax Credit transaction. On November 7, 2013, the Company entered into a transaction with JP Morgan Chase (JPM) related to an investment in plant and equipment within the Company’s Architectural Glass segment (the Project) whereby the Company received $7.8 million of cash from a qualified New Markets Tax Credit program (NMTC). The NMTC was provided for in the Community Renewal Tax Relief Act of 2000 and is intended to induce investment in underserved and impoverished areas of the United States. The Act permits taxpayers, whether companies or individuals, to claim credits against their federal income taxes for up to 39 percent of investments in qualified, active low-income businesses or ventures.

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 Company has concluded that the entities created in relation to the NMTC transaction are consolidated as variable-interest entities.

Based on the contractual arrangements that obligate the Company to deliver tax benefits to JPM, the Company has included the value of JPM’s contribution in other non-current liabilities within the 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 the Company’s 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 employment practices, workers compensation, general liability 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.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies and Related Data

Summary of Significant Accounting Policies and Related Data

Basis of Consolidation. The accompanying consolidated financial statements include the accounts of Apogee Enterprises, Inc., a Minnesota corporation, and all majority-owned subsidiaries (the Company). Transactions between Apogee and its subsidiaries have been eliminated in consolidation.

The results of Alumicor Limited (Alumicor), which the Company acquired on November 5, 2013, are included in the Company's Architectural Framing Systems segment. Refer to Note 6 for further information regarding the acquisition of Alumicor and its treatment in the consolidated financial statements.

GlassecViracon's fiscal year ends December 31 and its results are incorporated into the consolidated financial statements on a two-month lag. There were no significant intervening events that would have materially affected our consolidated financial statements had they been recorded during the year ended February 28, 2015.

Fiscal Year. Apogee's fiscal year ends on the Saturday closest to the last day of February. Fiscal 2015, 2014 and 2013 each consisted of 52 weeks.

Financial Instruments. Unless otherwise noted, the carrying amount of the Company's financial instruments approximates fair value.

Cash and Cash Equivalents. Investments with an original maturity of three months or less are included in cash and cash equivalents. Cash equivalents are stated at cost, which approximates fair value, and consist primarily of money market funds.

Investments. The Company has marketable securities consisting of high-quality municipal bonds. The securities are classified as “available for sale” and are carried at fair value based on prices from recent trades of similar securities. The Company tests for other than temporary losses on a quarterly basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If a decline in the fair value of a security is deemed by management to be other-than-temporary, the investment is written down to fair value, and the amount of the write-down is included in net earnings.

The Company also has investments in mutual funds as a long-term funding source for the deferred compensation plan. The mutual fund investments are recorded at estimated fair value, based on quoted market prices, and are included in other non-current assets in the consolidated balance sheet.

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.

During the fourth quarter of fiscal 2015, the Company changed its method of accounting for those inventories which were accounted for under the last-in, first-out (“LIFO”) method (53 percent of total fiscal 2014 inventories) to the FIFO method. The Company believes that this change is preferable as it provides uniformity across the Company's operations with respect to the method of inventory accounting, better reflects the current value of inventories on the consolidated balance sheets, aligns the accounting with the physical flow of inventory, and better matches revenues with associated expenses.

The change was applied retrospectively to March 3, 2012. The resulting impact to our consolidated balance sheets as of March 1, 2014 is as follows:

	March 1, 2014
(In thousands)	As Originally Reported		LIFO to FIFO Adjustment			Retrospectively Adjusted
Inventories, net	$	47,982	$	5,453		$	53,435
Current deferred tax assets	3,529		(815		)	2,714
Non-current deferred tax liabilities	7,403		1,164			8,567
Retained earnings	225,367		3,474			228,841

No retrospective adjustments were made to the consolidated results of operations or consolidated statements of cash flow as they were immaterial for all periods presented, resulting in an immaterial adjustment recorded to the consolidated results of operations and consolidated balance sheets during the fourth quarter of fiscal 2015 of approximately $0.1 million.

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 income as a reduction of or increase 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. The Company accounts for goodwill and intangible assets in accordance with applicable accounting standards.

The Company tests goodwill of each of its reporting units for impairment annually in connection with its fourth-quarter planning process or more frequently if impairment indicators exist. The Company has determined that each of its business units represents a reporting unit in accordance with applicable accounting standards. During the fourth quarter of fiscal 2015, the Company completed its annual impairment test using discounted cash flow methodologies for valuing its reporting units as no market comparables were identified. There have not been any material changes in the impairment loss assessment methodology made during the past three fiscal years. The estimates of fair value for the reporting units were found to be in excess of their carrying value, and, therefore, no impairment charge was recorded.

Intangible assets with discrete useful lives are amortized over their estimated useful lives. The Company has reassessed the useful lives of its identifiable intangible assets and determined that the remaining lives were appropriate.

Long-Lived Assets. The carrying value of long-lived assets, such as property, plant and equipment, and definite-lived intangible assets is reviewed when impairment indicators exist as required under generally accepted accounting principles. We consider many factors, including short- and long-term projections of future performance associated with these assets. If this review indicates that the long-lived assets will not be recoverable, the carrying value of such assets will be reduced to estimated fair value.

Self-Insurance. The Company obtains commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, architect's and engineer's errors and omissions risk, and other miscellaneous coverages. However, a reasonable amount of risk is retained on a self-insured basis primarily through a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism). Reserve requirements are established based on actuarial projections of ultimate losses. Losses estimated to be paid within 12 months are classified as accrued self-insurance reserves, while losses expected to be payable in later periods are included in long-term self-insurance reserves. Additionally, we maintain a self-insurance reserve for our health insurance programs maintained for the benefit of our eligible employees. We estimate a reserve based on historical levels of amounts incurred but not reported, which is included in accrued self-insurance reserves.

Environmental Liability. In accordance with accounting standards, we recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated. The cost of the clean-up is estimated by engineering, financial and legal specialists based on current 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. As part of the acquisition of Tubelite Inc. in fiscal 2008, the Company acquired property which contains historical environmental conditions that the Company intends to remediate. At February 28, 2015, the reserve was $1.8 million. The reserve for environmental liabilities is included in other current and non-current liabilities in the consolidated balance sheets.

Foreign Currency. For foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated at the period-end exchange rates and income statement accounts are translated using the average exchange rates prevailing during the year. Translation adjustments are reflected in accumulated other comprehensive loss in the consolidated balance sheets.

From time to time, the Company may enter into short duration foreign currency contracts to hedge foreign currency risks. There is no material foreign currency risk related to these contracts as they generally have an original maturity date of less than one year.

Revenue Recognition. Generally, our sales terms are “free on board” (FOB) shipping point or FOB destination for our product-type sales, and revenue is recognized when title has transferred. However, the Company's Architectural Services segment business enters into fixed-price contracts for full-service commercial building glass installation and renovation services, which are accounted for as construction-type 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. The contracts entered into clearly specify the enforceable rights of the parties, the consideration and the terms of settlement, and both parties can be expected to satisfy all obligations under the contract. Approximately 25 percent, 26 percent and 27 percent of our consolidated net sales in fiscal 2015, 2014 and 2013, respectively, were recorded on a percentage-of-completion basis. Under the methodology, the Company compares the total costs incurred to date to the total estimated costs for each contract, and records that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. Given our ability to make reasonable estimates of our total contract revenues and total contract costs, we believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of precision in measuring progress toward completion of the installation contracts. 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 when they have been approved by customers. 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 revenues. The costs incurred by the Company for shipping and handling are reported as cost of sales.

Research and Development. Research and development expenses are charged to operations as incurred, and were $6.5 million, $7.8 million and $6.8 million for fiscal 2015, 2014 and 2013, respectively. Of these amounts, $2.4 million, $2.1 million and $1.6 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 expenses are charged to operations as incurred and were $1.1 million in fiscal 2015, $1.2 million in fiscal 2014, and $1.4 million in fiscal 2013. They are included in selling, general and administrative expenses in the consolidated results of operations.

Income Taxes. The Company accounts for income taxes as prescribed by applicable accounting standards, which requires use of the asset and liability method. This method recognizes deferred tax assets and liabilities based upon the future tax consequences of temporary differences between financial and tax reporting. See Note 13 for additional information regarding income taxes.

Accounting Estimates. The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting period. Amounts subject to significant estimates and assumptions include, but are not limited to, assessment of recoverability of long-lived assets, including goodwill, insurance reserves, warranty reserves, net sales recognition for construction contracts, income tax provisions and liabilities; and the status of outstanding disputes and claims. Actual results could differ from those estimates.

New Accounting Standards.In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11 (ASU 2013-11), Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, as a reduction to a deferred tax asset in the financial statements for a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists with certain exceptions. The Company elected to prospectively adopt ASU 2013-11 in the first quarter of fiscal 2015. The Company's adoption of ASU 2013-11 resulted in a $0.5 million reclassification from unrecognized tax benefits to deferred tax liabilities in the consolidated balance sheets.

In May 2014, the FASB issued a standard on revenue from contracts with customers. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that 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, 2016, Apogee's fiscal 2018. The Company is currently evaluating the impact that this new standard will have on its consolidated financial statements. 

No other new accounting pronouncements issued or effective during fiscal 2015 have had or are expected to have a material impact on the consolidated financial statements.

Subsequent Events. In connection with preparing the audited consolidated financial statements for the year ended February 28, 2015, 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.

Shareholders' Equity

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

Share Repurchases

During fiscal 2004, the Board of Directors authorized a share repurchase program of 1,500,000 shares of common stock. The Board of Directors increased this authorization by 750,000 shares in January 2008 and by 1,000,000 in October 2008. The Company purchased 203,509 shares under the program during fiscal 2015, for a total cost of $6.9 million. There were no share repurchases during fiscal 2014 or 2013. The Company has purchased a total of 2,482,632 shares, at a total cost of $36.5 million, since the inception of this program and has remaining authority to repurchase 767,368 shares under this program, which has no expiration date.

In addition to the shares repurchased according to this repurchase plan, during fiscal 2015, 2014 and 2013 the Company also purchased $5.2 million, $3.6 million and $1.5 million, respectively, of Company stock from employees in order to satisfy stock-for-stock option exercises or withholding tax obligations related to stock-based compensation, pursuant to terms of board and shareholder approved compensation plans.
