SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 26, 2015
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES OPERATIONS We design, manufacture and market wood and wood-alternative products for large home centers and other retailers, structural lumber, engineered wood components, framing services, and other products for the construction market, and specialty wood packaging, components, packing materials, and other wood-based products for various industries. PRINCIPLES OF CONSOLIDATION The consolidated financial statements include our accounts and those of our wholly-owned and majority-owned subsidiaries and partnerships. In addition, we consolidate any entity which we own 50% or more and exercise control. Intercompany transactions and balances have been eliminated. NONCONTROLLING INTEREST IN SUBSIDIARIES Noncontrolling interest in results of operations of consolidated subsidiaries represents the noncontrolling shareholders' share of the income or loss of various consolidated subsidiaries. The noncontrolling interest reflects the original investment by these noncontrolling shareholders combined with their proportional share of the earnings or losses of these subsidiaries, net of distributions paid. FISCAL YEAR Our fiscal year is a 52 or 53 week period, ending on the last Saturday of December. Unless otherwise stated, references to 2015 , 2014 , and 2013 relate to the fiscal years ended December 26, 2015 , December 27, 2014 , and December 28, 2013 , respectively. Fiscal years 2015 , 2014 , and 2013 were comprised of 52 weeks. FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS We follow ASC Topic 820, Fair Value Measurements and Disclosures , which provides a consistent definition of fair value, focuses on exit price, prioritizes the use of market-based inputs over entity-specific inputs for measuring fair value and establishes a three-tier hierarchy for fair value measurements. This topic requires fair value measurements to be classified and disclosed in one of the following three categories: • Level 1 — Financial instruments with unadjusted, quoted prices listed on active market exchanges. • Level 2 — Financial instruments lacking unadjusted, quoted prices from active market exchanges, including over-the-counter traded financial instruments. Financial instrument values are determined using prices for recently traded financial instruments with similar underlying terms and direct or indirect observational inputs, such as interest rates and yield curves at commonly quoted intervals. • Level 3 — Financial instruments not actively traded on a market exchange and there is little, if any, market activity. Values are determined using significant unobservable inputs or valuation techniques. CASH AND CASH EQUIVALENTS Cash and cash equivalents consist of cash and highly-liquid investments purchased with an original maturity of three months or less. Restricted cash consists of amounts required to be held for loss funding totaling $0.6 and $0.4 million as of December 26, 2015 and December 27, 2014 , respectively. INVESTMENTS Investments are deemed to be "available for sale" and are, accordingly, carried at fair value being the quoted market value. Unrealized investment gains or losses, net of deferred taxes, are reported as a separate component of comprehensive income or loss until sold. ACCOUNTS RECEIVABLE AND ALLOWANCES We perform periodic credit evaluations of our customers and generally do not require collateral. Accounts receivable are due under a range of terms we offer to our customers. Discounts are offered, in most instances, as an incentive for early payment. We base our allowances related to receivables on historical credit and collections experience, and the specific identification of other potential problems, including the general economic climate. Actual collections can differ, requiring adjustments to the allowances. Individual accounts receivable balances are evaluated on a monthly basis, and those balances considered uncollectible are charged to the allowance. The following table presents the activity in our accounts receivable allowances (in thousands): Beginning Balance Additions Charged to Costs and Expenses Deductions* Ending Balance Year Ended December 26, 2015: Allowance for possible losses on accounts receivable $ 2,390 $ 20,538 $ (20,256 ) $ 2,672 Year Ended December 27, 2014: Allowance for possible losses on accounts receivable $ 2,060 $ 18,871 $ (18,541 ) $ 2,390 Year Ended December 28, 2013: Allowance for possible losses on accounts receivable $ 2,550 $ 17,114 $ (17,604 ) $ 2,060 * Includes accounts charged off, discounts given to customers and actual customer returns and allowances. We record estimated sales returns, discounts, and other applicable adjustments as a reduction of net sales in the same period revenue is recognized. Accounts receivable retainage amounts related to long term construction contracts totaled $6.5 million and $6.0 million as of December 26, 2015 and December 27, 2014 , respectively. All amounts are expected to be collected within 18 months . Concentration of accounts receivable related to our largest customer totaled $39.1 million and $26.5 million as of December 26, 2015 and December 27, 2014 , respectively. NOTES RECEIVABLE AND ALLOWANCES We have written agreements to receive repayment of funds borrowed from us, consisting of principal as well as any accrued interest, at a specified future date. We record a valuation allowance relating to these agreements for the portion that is expected to be uncollectible. The current portion of notes receivable, net of allowance, totaled $2.0 million and $5.2 million at December 26, 2015 and December 27, 2014 , respectively and are included in “Other Current Assets”. The long-term portion of notes receivable, net of allowance, totaled $2.4 million and $3.0 million at December 26, 2015 and December 27, 2014 , respectively and are included in “Other Assets”. The following table presents the activity in our notes receivable allowances (in thousands): Beginning Balance Additions Deductions Ending Balance Year Ended December 26, 2015: $ 826 $ — $ (826 ) $ — Year Ended December 27, 2014: $ 1,025 $ 1,599 $ (1,798 ) $ 826 Year Ended December 28, 2013: 3,226 $ 887 (3,088 ) $ 1,025 INVENTORIES Inventories are stated at the lower of cost or market. The cost of inventories includes raw materials, direct labor, and manufacturing overhead. Cost is determined on a weighted average basis. Raw materials consist primarily of unfinished wood products expected to be manufactured or treated prior to sale, while finished goods represent various manufactured and treated wood products ready for sale. We have inventory on consignment at customer locations valued at $11.7 million as of December 26, 2015 and $12.9 million as of December 27, 2014 . During 2015, management decided to discontinue certain product lines in our Gulf region which resulted in a $2.5 million inventory write-down. PROPERTY, PLANT, AND EQUIPMENT Property, plant, and equipment are stated at cost. Expenditures for renewals and betterments are capitalized, and maintenance and repairs are expensed as incurred. Amortization of assets held under capital leases is included in depreciation and amortized over the shorter of the estimated useful life of the asset or the lease term. Depreciation is computed principally by the straight-line method over the estimated useful lives of the assets as follows: Land improvements 5 to 15 years Buildings and improvements 10 to 32 years Machinery, equipment and office furniture 2 to 8 years LONG-LIVED ASSETS In accordance with ASC 360, Property, Plant, and Equipment (“ASC 360”), when an indicator of potential impairment exists, we evaluate the recoverability of our long-lived assets by determining whether unamortized balances could be recovered through undiscounted future operating cash flows over the remaining lives of the assets. If the sum of the expected future cash flows was less than the carrying value of the assets, an impairment loss would be recognized for the excess of the carrying value over the fair value. GOODWILL Our annual testing date for evaluating goodwill and indefinite-lived intangible asset impairment in the first day of the Company’s fourth fiscal quarter for all reporting units. Additionally, the Company reviews various triggering events throughout the year to ensure that a mid-year impairment analysis is not required. The reasonableness of our segment values determined in our valuation is measured against our market capitalization at the measurement date. FOREIGN CURRENCY Our foreign operations use the local currency as their functional currency. Accordingly, assets and liabilities are translated at exchange rates as of the balance sheet date and revenues and expenses are translated using weighted average rates, with translation adjustments included as a separate component of shareholders' equity. Gains and losses arising from re-measuring foreign currency transactions are included in earnings. INSURANCE RESERVES Our wholly-owned insurance captive, Ardellis Insurance Ltd.(“Ardellis”), was incorporated on April 21, 2001 under the laws of Bermuda and is licensed as a Class 3 insurer under the Insurance Act 1978 of Bermuda. We are primarily self-insured for certain employee health benefits, and have self-funded retentions for general liability, automobile liability, property and workers' compensation. We are fully self-insured for environmental liabilities. The general liability, automobile liability, property, workers' compensation, and certain environmental liabilities are managed through Ardellis; the related assets and liabilities of which are included in the consolidated financial statements as of December 26, 2015 and December 27, 2014 . Our policy is to accrue amounts equal to actuarially determined or internally computed liabilities. The actuarial and internal valuations are based on historical information along with certain assumptions about future events. Changes in assumptions for such matters as legal actions, medical cost trends, and changes in claims experience could cause these estimates to change in the future. In addition to providing coverage for the Company, Ardellis provides Excess Loss Insurance (primarily medical and prescription drug) to certain third parties. As of December 26, 2015 , Ardellis had 21 such contracts in place. The contracts have aggregate coverage loss limits based on the election of the third parties. Reserves associated with these contracts were $2.0 million at December 26, 2015 and $1.8 million at December 27, 2014 , and are accrued based on third party actuarial valuations of the expected future liabilities. INCOME TAXES Deferred income tax assets and liabilities are computed for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates. Valuation allowances are established when necessary to reduce deferred income tax assets to the amounts expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred income tax assets and liabilities. The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17 - Income Taxes (Topic 740) : Balance Sheet Classification of Deferred Taxes , on November 2, 2015, which simplifies the accounting for deferred tax assets and deferred tax liabilities. In accordance with this standard, the Company has early adopted the presentation of deferred income taxes, which requires all deferred tax assets and deferred tax liabilities to be classified as noncurrent as opposed to the former US GAAP Standard which requires entities to split their deferred tax assets and deferred tax liabilities between current and noncurrent based on the balance sheet classification of the related asset or liability. At the end of 2015 and prospectively, the deferred tax assets and deferred tax liabilities were classified as noncurrent. DEBT The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-03 - Simplifying the Presentation of Debt Issuance Costs on April 7, 2015 and effective for fiscal years beginning after December 15, 2015. The ASU requires the presentation of debt issuance costs in the balance sheet as a direct deduction from the recognized debt liability rather than as an asset and amortization of the costs is reported as interest expense. In accordance with ASU 2015-03, the Company will comply with this ASU during the first interim reporting period of 2016. REVENUE RECOGNITION Revenue is recognized at the time the product is shipped to the customer. Generally, title passes at the time of shipment. In certain circumstances, the customer takes title when the shipment arrives at the destination. However, our shipping process is typically completed the same day. Earnings on construction contracts are reflected in operations using percentage-of-completion accounting, under either the cost to cost or units of delivery methods, depending on the nature of the business at individual operations. Under percentage-of-completion using the cost to cost method, revenues and related earnings on construction contracts are measured by the relationships of actual costs incurred related to the total estimated costs. Under percentage-of-completion using the units of delivery method, revenues and related earnings on construction contracts are measured by the relationships of actual units produced related to the total number of units. Revisions in earnings estimates on the construction contracts are recorded in the accounting period in which the basis for such revisions becomes known. Projected losses on individual contracts are charged to operations in their entirety when such losses become apparent. Our construction contracts are generally entered into with a fixed price and completion of the projects can range from 6 to 18 months in duration. Therefore, our operating results are impacted by, among many other things, labor rates and commodity costs. During the year, we update our estimated costs to complete our projects using current labor and commodity costs and recognized losses to the extent that they exist. The following table presents the balances of percentage-of-completion accounts on December 26, 2015 and December 27, 2014 which are included in other current assets and other accrued liabilities, respectively (in thousands): 2015 2014 Cost and Earnings in Excess of Billings $ 3,624 $ 5,244 Billings in Excess of Cost and Earnings 4,978 4,682 SHIPPING AND HANDLING OF PRODUCT Shipping and handling costs that are charged to and reimbursed by the customer are recognized as revenue. Costs incurred related to the shipment and handling of products are classified in cost of goods sold.

USE OF ACCOUNTING ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us 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 financial statements as well as the reported amounts of revenues and expenses during the reporting period. We believe our estimates to be reasonable; however, actual results could differ from these estimates.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of the purchase price over the fair value of net tangible and identifiable intangible assets of acquired businesses. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment tests at least annually in accordance with ASC 350, Intangibles-Goodwill and Other. We review the carrying amounts of goodwill and other non-amortizable intangibles by reporting unit to determine if such assets may be impaired. As the carrying amount of these assets are recoverable based upon a discounted cash flow and market approach analysis, no impairment was recognized.

Deferred Compensation Arrangements [Abstract]
DEFERRED COMPENSATION	DEFERRED COMPENSATION We have a program whereby certain executives irrevocably elected to defer receipt of certain compensation in 1985 through 1988. Deferred compensation payments to these executives will commence upon their retirement. We purchased life insurance on these executives, payable to us in amounts which, if assumptions made as to mortality experience, policy dividends, and other factors are realized, will accumulate cash values adequate to reimburse us for all payments for insurance and deferred compensation obligations. In the event cash values are not sufficient to fund such obligations, the program allows us to reduce benefit payments to such amounts as may be funded by accumulated cash values. The deferred compensation liabilities and related cash surrender value of life insurance policies totaled $2.3 million and $2.0 million on December 26, 2015 and December 27, 2014 , respectively, and are included "Other Liabilities" and "Other Assets," respectively. We also maintain a non-qualified deferred compensation plan (the "Plan") for the benefit of senior management employees who may elect to defer a portion of their annual bonus payments and salaries. The Plan provides investment options similar to our 401(k) plan, including our stock. The investment in our stock is funded by the issuance of shares to a Rabbi trust, and may only be distributed in kind. Assets held by the Plan totaled approximately $0.8 million and $0.7 million on December 26, 2015 and December 27, 2014 respectively, and are included in "Other Assets." Related liabilities totaled $13.3 million and $9.7 million on December 26, 2015 and December 27, 2014 , respectively, and are included in "Other Liabilities" and "Shareholders' Equity." Assets associated with the Plan are recorded at fair market value. The related liabilities are recorded at fair market value, with the exception of obligations associated with investments in our stock which are recorded at the market value on the date of deferral.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
COMMON STOCK	COMMON STOCK In April 2002, our shareholders approved the 2002 Employee Stock Purchase Plan ("Stock Purchase Plan") to succeed the Employee Stock Purchase Plan originally approved in 1994. In April 2008, our shareholders authorized additional shares to be allocated to the Stock Purchase Plan and extended the term of the Stock Purchase Plan to 2018. The plan allows eligible employees to purchase shares of our stock at a share price equal to 85% of fair market value on the purchase date. We have expensed the fair value of the compensation associated with these awards, which approximates the discount. The amount of expense is nominal. In April 1994, our shareholders approved the Directors’ Retainer Stock Plan ("Stock Retainer Plan"). In April 2007, our shareholders authorized additional shares to be issued pursuant to this plan. The Stock Retainer Plan allows eligible members of the Board of Directors to defer their retainer fees and receive shares of our stock at the time of their retirement, disability or death. The number of shares to be received is equal to the amount of the retainer fee deferred multiplied by 110% , divided by the fair market value of a share of our stock at the time of deferral. The number of shares is increased by the amount of dividends paid on the Company’s common stock. We recognized expense for this plan of $0.6 million in 2015 , $0.6 million in 2014 , and $0.4 million in 2013 . On April 15, 2010, our shareholders approved an amended and restated Long Term Stock Incentive Plan (the "LTSIP”). The LTSIP reserves 1,000,000 shares, plus a balance of unused shares from prior plans of approximately 1.6 million shares, plus an annual increase of no more than 200,000 shares per year which may be added on the dates of our annual shareholder meetings. The LTSIP provides for the grant of stock options, stock appreciation rights, restricted stock, performance shares and other stock-based awards.

On November 14, 2001, the Board of Directors approved a share repurchase program (which succeeded a previous program) allowing us to repurchase up to 2.5 million shares of our common stock. On October 14, 2010, our Board authorized an additional 2 million shares to be repurchased under our share repurchase program. We repurchased 105,012 and 13,613 shares under this program in 2014 and 2015, respectively. As of December 26, 2015 , the cumulative total authorized shares available for repurchase is approximately 2.9 million shares.

Based upon the business activity and the nature of the assets of these subsidiaries, our ability to realize a future benefit from these carryforwards is in doubt, therefore we have established an allowance against the amount of the future benefit. The capital loss has an unlimited carryforward and therefore will not expire unless there is a change in control of the subsidiary. ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES ASC 740, Income Taxes (“ASC 740”) clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. ASC 740 also provides guidance on derecognition, measurement, classification, interest and penalties, and disclosure requirements. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): 2015 2014 2013 Gross unrecognized tax benefits beginning of year $ 1,793 $ 1,923 $ 1,531 Increase in tax positions for prior years — — 230 Increase in tax positions for current year 754 556 481 Settlements with taxing authorities — — — Lapse in statute of limitations (338 ) (686 ) (319 ) Gross unrecognized tax benefits end of year $ 2,209 $ 1,793 $ 1,923 Our effective tax rate would have been affected by the unrecognized tax benefits had this amount been recognized as a reduction to income tax expense. We recognized interest and penalties for unrecognized tax benefits in our provision for income taxes. The liability for unrecognized tax benefits included accrued interest and penalties of $0.2 million , $0.2 million and $0.2 million at December 26, 2015 , December 27, 2014 , and December 28, 2013 , respectively. We file income tax returns in the United States and in various state, local and foreign jurisdictions. The federal and a majority of state and foreign jurisdictions are no longer subject to income tax examinations for years before 2012. A number of routine state and local examinations are currently ongoing. Due to the potential for resolution of state examinations, and the expiration of various statutes of limitation, and new positions that may be taken, it is reasonably possible that the amounts of unrecognized tax benefits could change in the next twelve months.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES, AND GUARANTEES	COMMITMENTS, CONTINGENCIES, AND GUARANTEES We are self-insured for environmental impairment liability, including certain liabilities which are insured through a wholly owned subsidiary, Ardellis Insurance Ltd., a licensed captive insurance company. We own and operate a number of facilities throughout the United States that chemically treat lumber products. In connection with the ownership and operation of these and other real properties, and the disposal or treatment of hazardous or toxic substances, we may, under various federal, state, and local environmental laws, ordinances, and regulations, be potentially liable for removal and remediation costs, as well as other potential costs, damages, and expenses. Environmental reserves, calculated with no discount rate, have been established to cover remediation activities at wood preservation facilities in Stockertown, PA; Elizabeth City, NC; Auburndale, FL; and Medley, FL. In addition, a reserve was established for our facility in Thornton, CA to remove certain lead containing materials which existed on the property at the time of purchase. On a consolidated basis, we have reserved approximately $3.5 million on December 26, 2015 and December 27, 2014 , representing the estimated costs to complete future remediation efforts. These amounts have not been reduced by an insurance receivable. Many of our wood treating operations utilize "Subpart W" drip pads, defined as hazardous waste management units by the Environmental Protection Agency. The rules regulating drip pads require that the pad be “closed” at the point that it is no longer intended to be used for wood treating operations or to manage hazardous waste. Closure involves identification and disposal of contaminants which are required to be removed from the facility. The cost of closure is dependent upon a number of factors including, but not limited to, identification and removal of contaminants, cleanup standards that vary from state to state, and the time period over which the cleanup would be completed. Based on our present knowledge of existing circumstances, it is considered probable that these costs will approximate $0.6 million . As a result, this amount is recorded in other long-term liabilities on December 26, 2015 . In February 2014, one of our operations was served with a federal grand jury subpoena from the Southern District of New York. The subpoena was issued in connection with an investigation being conducted by the US Attorney's Office for the Southern District of New York. The subpoena requested documents relating to a developer and construction projects for which our operation had provided materials and labor. Following receipt of the subpoena, the Audit Committee of the Company’s Board of Directors retained outside counsel to conduct an internal investigation and respond to the subpoena. The Company cooperated in all respects with the US Attorney's Office, complied with this subpoena and voluntarily provided additional information. As a result of the internal investigation, in April 2014, two Company employees were terminated for violating the Company’s Code of Conduct and Business Ethics. In May 2015, those ex-employees were indicted by the grand jury . The Company has not been named as a target and continues to cooperate with the US Attorney's Office in this matter; however, because of the duration and unique nature of this proceeding, any potential, adverse financial implications to the Company are uncertain. As of December 26, 2015 and December 27, 2014 , we have an accrual balance of $1.6 million , respectively, related to anti-dumping duty assessments imposed on steel nails imported from China. In addition, on December 26, 2015 , we were parties either as plaintiff or a defendant to a number of lawsuits and claims arising through the normal course of our business. In the opinion of management, our consolidated financial statements will not be materially affected by the outcome of these contingencies and claims. On December 26, 2015 , we had outstanding purchase commitments on capital projects of approximately $3.3 million . We provide a variety of warranties for products we manufacture. Historically, warranty claims have not been material. We distribute products manufactured by other companies, some of which are no longer in business. While we do not warrant these products, we have received claims as a distributor of these products when the manufacturer no longer exists or has the ability to pay. Historically, these costs have not had a material affect on our consolidated financial statements. As part of our operations, we supply building materials and labor to site-built construction projects or we jointly bid on contracts with framing companies for such projects. In some instances we are required to post payment and performance bonds to insure the project owner the products and installation services are completed in accordance with our contractual obligations. We have agreed to indemnify the surety for claims made against the bonds. As of December 26, 2015 , we had approximately $0.2 million in outstanding payment and performance bonds, for projects in process, which should expire during the next two years. In addition, approximately $12.4 million in payment and performance bonds are outstanding for completed projects which are still under warranty. On December 26, 2015 we had outstanding letters of credit totaling $25.4 million , primarily related to certain insurance contracts and industrial development revenue bonds described further below. In lieu of cash deposits, we provide irrevocable letters of credit in favor of our insurers to guarantee our performance under certain insurance contracts. We currently have irrevocable letters of credit outstanding totaling approximately $15.6 million for these types of insurance arrangements. We have reserves recorded on our balance sheet, in accrued liabilities, that reflect our expected future liabilities under these insurance arrangements. We are required to provide irrevocable letters of credit in favor of the bond trustees for all of the industrial development revenue bonds that have been issued. These letters of credit guarantee principal and interest payments to the bondholders. We currently have irrevocable letters of credit outstanding totaling approximately $9.8 million related to our outstanding industrial development revenue bonds. These letters of credit have varying terms but may be renewed at the option of the issuing banks. Certain wholly owned domestic subsidiaries have guaranteed the indebtedness of Universal Forest Products, Inc. in certain debt agreements, including the Series 2012 Senior Notes and our revolving credit facility. The maximum exposure of these guarantees is limited to the indebtedness outstanding under these debt arrangements and this exposure will expire concurrent with the expiration of the debt agreements.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING ASC 280, Segment Reporting (“ASC 280”), defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company operates manufacturing, treating and distribution facilities throughout North America, but primarily in the United States. The Company manages the operations of its individual locations primarily through a geographic reporting structure under which each location is included in a region and regions are included in divisions. The exceptions to this geographic reporting and management structure are (a) the Company's Alternative Materials Division, which offers a Due to changes in management structure, we revised our operating segments at the beginning of fiscal 2015. Our operating segments currently consist of the North, South, West, Alternative Materials, International, Corporate, and All Other. Our previous operating segments, immediately prior to the current fiscal year, consisted of Eastern, Western, Site-Built, Corporate, and All Other. The Company's new North and South reporting segments represent the segregation of the former Eastern segment with the following adjustments: ú The Site-Built unit previously was a separate operating and reportable segment; however the recent management structure reorganization resulted in the Site-Built unit reporting through (and is now apart of) the North segment. ú UFPD which previously was included in the All Other segment, is now included as part of the North segment. With respect to the facilities in the north, south, and west segments, these facilities generally supply the three markets the Company serves nationally - Retail, Industrial, and Construction. Also, substantially all of our facilities support customers in the immediate geographical region surrounding the facility. Prior year amounts have been reclassified to our new segments. Our Alternative Materials and International divisions have been included in the “All Other” column of the table below. The “Corporate” column includes unallocated administrative costs and certain incentive compensation expense. 2015 North South West All Other Corporate Total Net sales to outside customers $ 922,092 $ 656,550 $ 1,133,398 $ 175,031 $ — $ 2,887,071 Intersegment net sales 51,796 29,940 58,412 13,673 — 153,821 Interest expense — 296 516 52 4,269 5,133 Amortization expense 267 9 2,467 788 — 3,531 Depreciation expense 7,901 6,255 13,033 3,707 6,814 37,710 Segment earnings from operations 53,879 30,740 70,220 3,038 (22,410 ) 135,467 Segment assets 291,614 185,818 369,077 98,004 163,166 1,107,679 Capital expenditures 9,622 6,138 13,356 6,698 7,708 43,522 2014 North South West All Other Corporate Total Net sales to outside customers $ 840,277 $ 611,700 $ 1,062,565 $ 145,787 $ — $ 2,660,329 Intersegment net sales 37,624 20,224 47,737 12,783 — 118,368 Interest expense — 323 39 — 3,905 4,267 Amortization expense 331 10 1,358 711 — 2,410 Depreciation expense 7,060 5,700 11,029 4,082 6,042 33,913 Segment earnings from operations 32,988 24,474 53,575 3,155 (16,825 ) 97,367 Segment assets 303,213 201,245 351,557 85,661 82,124 1,023,800 Capital expenditures 10,887 8,875 11,984 3,879 9,680 45,305 2013 North South West All Other Corporate Total Net sales to outside customers $ 811,438 $ 568,237 $ 950,684 $ 140,089 $ — $ 2,470,448 Intersegment net sales 46,103 17,689 38,176 11,798 — 113,766 Interest expense — 356 48 — 4,447 4,851 Amortization expense 331 8 1,416 718 — 2,473 Depreciation expense 6,541 4,762 9,830 4,288 5,670 31,091 Segment earnings from operations 21,167 23,680 42,003 (1,850 ) (10,732 ) 74,268 Segment assets 287,382 178,008 300,443 79,510 71,644 916,987 Capital expenditures 8,390 6,010 11,069 6,285 8,269 40,023 In 2015 , 2014 , and 2013 , 19% , 17% , and 17% of net sales, respectively, were to a single customer.

FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS	FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS We follow ASC Topic 820, Fair Value Measurements and Disclosures , which provides a consistent definition of fair value, focuses on exit price, prioritizes the use of market-based inputs over entity-specific inputs for measuring fair value and establishes a three-tier hierarchy for fair value measurements. This topic requires fair value measurements to be classified and disclosed in one of the following three categories: • Level 1 — Financial instruments with unadjusted, quoted prices listed on active market exchanges. • Level 2 — Financial instruments lacking unadjusted, quoted prices from active market exchanges, including over-the-counter traded financial instruments. Financial instrument values are determined using prices for recently traded financial instruments with similar underlying terms and direct or indirect observational inputs, such as interest rates and yield curves at commonly quoted intervals. • Level 3 — Financial instruments not actively traded on a market exchange and there is little, if any, market activity. Values are determined using significant unobservable inputs or valuation techniques.
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS Cash and cash equivalents consist of cash and highly-liquid investments purchased with an original maturity of three months or less.
INVESTMENTS	INVESTMENTS Investments are deemed to be "available for sale" and are, accordingly, carried at fair value being the quoted market value. Unrealized investment gains or losses, net of deferred taxes, are reported as a separate component of comprehensive income or loss until sold.
ACCOUNTS RECEIVABLE AND ALLOWANCES	We record estimated sales returns, discounts, and other applicable adjustments as a reduction of net sales in the same period revenue is recognized. ACCOUNTS RECEIVABLE AND ALLOWANCES We perform periodic credit evaluations of our customers and generally do not require collateral. Accounts receivable are due under a range of terms we offer to our customers. Discounts are offered, in most instances, as an incentive for early payment. We base our allowances related to receivables on historical credit and collections experience, and the specific identification of other potential problems, including the general economic climate. Actual collections can differ, requiring adjustments to the allowances. Individual accounts receivable balances are evaluated on a monthly basis, and those balances considered uncollectible are charged to the allowance.
NOTES RECEIVABLE AND ALLOWANCES	NOTES RECEIVABLE AND ALLOWANCES We have written agreements to receive repayment of funds borrowed from us, consisting of principal as well as any accrued interest, at a specified future date. We record a valuation allowance relating to these agreements for the portion that is expected to be uncollectible.
INVENTORIES	INVENTORIES Inventories are stated at the lower of cost or market. The cost of inventories includes raw materials, direct labor, and manufacturing overhead. Cost is determined on a weighted average basis. Raw materials consist primarily of unfinished wood products expected to be manufactured or treated prior to sale, while finished goods represent various manufactured and treated wood products ready for sale.
PROPERTY, PLANT, AND EQUIPMENT	PROPERTY, PLANT, AND EQUIPMENT Property, plant, and equipment are stated at cost. Expenditures for renewals and betterments are capitalized, and maintenance and repairs are expensed as incurred. Amortization of assets held under capital leases is included in depreciation and amortized over the shorter of the estimated useful life of the asset or the lease term.
LONG-LIVED ASSETS	LONG-LIVED ASSETS In accordance with ASC 360, Property, Plant, and Equipment (“ASC 360”), when an indicator of potential impairment exists, we evaluate the recoverability of our long-lived assets by determining whether unamortized balances could be recovered through undiscounted future operating cash flows over the remaining lives of the assets. If the sum of the expected future cash flows was less than the carrying value of the assets, an impairment loss would be recognized for the excess of the carrying value over the fair value.
GOODWILL	GOODWILL Our annual testing date for evaluating goodwill and indefinite-lived intangible asset impairment in the first day of the Company’s fourth fiscal quarter for all reporting units. Additionally, the Company reviews various triggering events throughout the year to ensure that a mid-year impairment analysis is not required. The reasonableness of our segment values determined in our valuation is measured against our market capitalization at the measurement date.
FOREIGN CURRENCY	FOREIGN CURRENCY Our foreign operations use the local currency as their functional currency. Accordingly, assets and liabilities are translated at exchange rates as of the balance sheet date and revenues and expenses are translated using weighted average rates, with translation adjustments included as a separate component of shareholders' equity. Gains and losses arising from re-measuring foreign currency transactions are included in earnings.
INSURANCE RESERVES	INSURANCE RESERVES Our wholly-owned insurance captive, Ardellis Insurance Ltd.(“Ardellis”), was incorporated on April 21, 2001 under the laws of Bermuda and is licensed as a Class 3 insurer under the Insurance Act 1978 of Bermuda. We are primarily self-insured for certain employee health benefits, and have self-funded retentions for general liability, automobile liability, property and workers' compensation. We are fully self-insured for environmental liabilities. The general liability, automobile liability, property, workers' compensation, and certain environmental liabilities are managed through Ardellis; the related assets and liabilities of which are included in the consolidated financial statements as of December 26, 2015 and December 27, 2014 . Our policy is to accrue amounts equal to actuarially determined or internally computed liabilities. The actuarial and internal valuations are based on historical information along with certain assumptions about future events. Changes in assumptions for such matters as legal actions, medical cost trends, and changes in claims experience could cause these estimates to change in the future. In addition to providing coverage for the Company, Ardellis provides Excess Loss Insurance (primarily medical and prescription drug) to certain third parties. As of December 26, 2015 , Ardellis had 21 such contracts in place. The contracts have aggregate coverage loss limits based on the election of the third parties. Reserves associated with these contracts were $2.0 million at December 26, 2015 and $1.8 million at December 27, 2014 , and are accrued based on third party actuarial valuations of the expected future liabilities.
INCOME TAXES	INCOME TAXES Deferred income tax assets and liabilities are computed for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates. Valuation allowances are established when necessary to reduce deferred income tax assets to the amounts expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred income tax assets and liabilities. The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17 - Income Taxes (Topic 740) : Balance Sheet Classification of Deferred Taxes , on November 2, 2015, which simplifies the accounting for deferred tax assets and deferred tax liabilities. In accordance with this standard, the Company has early adopted the presentation of deferred income taxes, which requires all deferred tax assets and deferred tax liabilities to be classified as noncurrent as opposed to the former US GAAP Standard which requires entities to split their deferred tax assets and deferred tax liabilities between current and noncurrent based on the balance sheet classification of the related asset or liability. At the end of 2015 and prospectively, the deferred tax assets and deferred tax liabilities were classified as noncurrent.
DEBT	DEBT The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-03 - Simplifying the Presentation of Debt Issuance Costs on April 7, 2015 and effective for fiscal years beginning after December 15, 2015. The ASU requires the presentation of debt issuance costs in the balance sheet as a direct deduction from the recognized debt liability rather than as an asset and amortization of the costs is reported as interest expense. In accordance with ASU 2015-03, the Company will comply with this ASU during the first interim reporting period of 2016.
REVENUE RECOGNITION	REVENUE RECOGNITION Revenue is recognized at the time the product is shipped to the customer. Generally, title passes at the time of shipment. In certain circumstances, the customer takes title when the shipment arrives at the destination. However, our shipping process is typically completed the same day. Earnings on construction contracts are reflected in operations using percentage-of-completion accounting, under either the cost to cost or units of delivery methods, depending on the nature of the business at individual operations. Under percentage-of-completion using the cost to cost method, revenues and related earnings on construction contracts are measured by the relationships of actual costs incurred related to the total estimated costs. Under percentage-of-completion using the units of delivery method, revenues and related earnings on construction contracts are measured by the relationships of actual units produced related to the total number of units. Revisions in earnings estimates on the construction contracts are recorded in the accounting period in which the basis for such revisions becomes known. Projected losses on individual contracts are charged to operations in their entirety when such losses become apparent. Our construction contracts are generally entered into with a fixed price and completion of the projects can range from 6 to 18 months in duration. Therefore, our operating results are impacted by, among many other things, labor rates and commodity costs. During the year, we update our estimated costs to complete our projects using current labor and commodity costs and recognized losses to the extent that they exist.
SHIPPING AND HANDLING OF PRODUCT	SHIPPING AND HANDLING OF PRODUCT Shipping and handling costs that are charged to and reimbursed by the customer are recognized as revenue. Costs incurred related to the shipment and handling of products are classified in cost of goods sold.
USE OF ACCOUNTING ESTIMATES	USE OF ACCOUNTING ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us 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 financial statements as well as the reported amounts of revenues and expenses during the reporting period. We believe our estimates to be reasonable; however, actual results could differ from these estimates.
