SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	A. 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; specialty wood packaging, components, packing materials, and other wood-based products for various industries; and design, manufacture, and install customized interior fixtures used in retail and commercial structures for various markets. 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 2017, 2016, and 2015 relate to the fiscal years ended December 30, 2017, December 31, 2016, and December 26, 2015, respectively. Fiscal year 2016 was comprised of 53 weeks, which contributed an additional $ 60 million in sales in 2016 compared to fiscal years 2017 and 2015, which 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 $0.5 million and $0.4 million as of December 30, 2017 and December 31, 2016, respectively. In November 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2016-18, “Statement of Cash Flows (Topic 230)” (ASU 2016-18). Under ASU 2016-18, an entity will be required to explain changes in the statement of cash flows during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this update should be applied using retrospective transition method to each period presented. Companies are required to adopt the new standard for fiscal years beginning after December 15, 2017. Early adoption of ASU 2016-18 is permitted, including adoption in an interim period. The Company has early adopted this standard during the first quarter of 2017. 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): Additions Charged to Beginning Costs and Ending Balance Expenses Deductions* Balance Year Ended December 30,2017: Allowance for possible losses on accounts receivable $ 2,845 $ 28,102 $ (28,523) $ 2,424 Year Ended December 31, 2016: Allowance for possible losses on accounts receivable $ 2,672 $ 28,405 $ (28,232) $ 2,845 Year Ended December 26, 2015: Allowance for possible losses on accounts receivable $ 2,390 $ 20,538 $ (20,256) $ 2,672 * 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 $ 4.8 million and $6.0 million as of December 30, 2017 and December 31, 2016, respectively. All amounts are expected to be collected within 18 months. Concentration of accounts receivable related to our largest customer totaled $55.9 million and $34.0 million as of December 30, 2017 and December 31, 2016, respectively. 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 $14.8 million as of December 30, 2017 and $12.2 million as of December 31, 2016. 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. LEASES In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2016‑02, “Leases (Topic 842)” (ASU 2016‑02). Under ASU 2016‑02, an entity will be required to recognize assets and liabilities for the rights and obligations created by leases on the entity’s balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016‑02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity’s leases. Companies are required to adopt the new standard for annual and interim periods beginning after December 15, 2018. Early adoption of ASU 2016‑02 is permitted. The FASB has tentatively decided to amend certain aspects of its new leasing standard in an attempt to provide a relief from implementation costs. Specifically, entities may elect not to restate their comparative periods in the period of adoption when transitioning to the new standard. The Company plans to continue to evaluate the effect of the new leasing guidance in 2018; therefore, the quantitative impact has not yet been determined however the Company anticipates only a balance sheet impact. GOODWILL Our annual testing date for evaluating goodwill and indefinite-lived intangible asset impairment is 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. 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 company, Ardellis Insurance Ltd.(“Ardellis”), was incorporated on April 21, 2001 under the laws of Bermuda and is licensed as a Class 3A insurer under the Insurance Act 1978 of Bermuda. On April 14, 2017 the U.S. Branch of Ardellis Insurance Ltd. was granted its Certificate of Authority to transact property and casualty insurance lines as an admitted carrier in the State of Michigan. 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 30, 2017 and December 31, 2016. 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 30, 2017, Ardellis had 30 such contracts in place. Reserves associated with these contracts were $3.4 million at December 30, 2017 and $2.5 million at December 31, 2016, 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. REVENUE RECOGNITION On May 28, 2014, the FASB issued ASU No. 2014‑09 (Accounting Standard Codification 606), Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. The Company is currently finalizing its evaluation of the impact of adopting this new guidance, which is not expected to materially impact the Company's financial condition or results of operations. The five-step model has been applied to existing contracts with customers, and based upon this review, the Company does not expect the adoption of ASU 2014-09 to have a material quantitative impact on its consolidated financial statements, as the timing of revenue recognition for product sales will continue to occur at the point of shipment. Other types of revenue, such as installation and framing, which are immaterial to our total revenue, will continue to be recognized over the appropriate period of time. As required by the standard, the Company expects to make additional disclosures related to the nature, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company will adopt this standard in the first quarter of fiscal year 2018 using the modified retrospective. 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 30, 2017 and December 31, 2016 which are included in other current assets and other accrued liabilities, respectively (in thousands): December 30, December 31, 2017 2016 Cost and Earnings in Excess of Billings $ 5,005 $ 2,573 Billings in Excess of Cost and Earnings 4,435 4,748 SHIPPING AND HANDLING OF PRODUCT Shipping and handling costs that are charged to and reimbursed by the customer are recognized as revenue.

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.

Cash borrowings are charged interest based upon an index selected by the Company, plus a margin that is determined based upon the index selected and upon the financial performance of the Company and certain of its subsidiaries. The Company is charged a facility fee on the entire amount of the lending commitment, at a per annum rate ranging from 15 to 32.5 basis points, also determined based upon the Company’s performance. The facility fee is payable quarterly in arrears. Outstanding letters of credit extended on our behalf on December 30, 2017 and December 31, 2016 aggregated $26.5 million and $25.5 million; respectively, which includes approximately $9.8 million related to industrial development revenue bonds.

DEFERRED COMPENSATION
DEFERRED COMPENSATION	H. 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 $2.0 million and $2.4 million on December 30, 2017 and December 31, 2016, 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 $ 1.0 million and $0. 9 million on December 30, 2017 and December 31, 2016 respectively, and are included in "Other Assets." Related liabilities totaled $ 22.6 million and $17.4 million on December 30, 2017 and December 31, 2016, 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.

COMMON STOCK
COMMON STOCK	I. 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 the cash portion of their retainer and committee fees and receive shares of our stock at the time of or following their retirement, disability or death. The number of shares to be received is equal to the amount of the cash portion of their retainer and committee fees 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 $1.7 million in 2017, $0.7 million in 2016, and $0.6 million in 2015. Effective January 1, 2017, this plan was amended to allow directors to defer payment of the annual retainer paid in the form of our common stock. 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 October 18, 2017, the Board of Directors approved a three-for-one split of the Company's outstanding shares of common stock effected as a stock dividend. On November 14, 2017, shareholders of record as of October 31, 2017, received two additional shares for each share held on the record date. There is no unrecognized compensation expense remaining for stock options in 2017, 2016, and 2015. A summary of the nonvested restricted stock awards granted under the LTSIP is as follows: Weighted- Unrecognized Average Weighted- Compensation Period to Restricted Average Grant Expense Recognize Awards Date Fair Value (in millions) Expense Nonvested at December 27, 2014 771,258 12.13 1.7 1.81 years Granted 228,963 18.00 Vested (364,926) 12.87 Forfeited (11,547) 16.28 Nonvested at December 26, 2015 623,748 13.66 5.2 2.53 years Granted 350,892 23.96 Vested (180,465) 15.66 Forfeited (2,643) 21.45 Nonvested at December 31, 2016 791,532 19.32 4.8 1.51 years Granted 388,248 32.03 Vested (141,111) 12.71 Forfeited (5,043) 30.14 Nonvested at December 30, 2017 1,033,626 $ 24.24 $ 7.1 1.31 years Under the Stock Purchase Plan and LTSIP, we recognized share-based compensation expense of $3.6 million, $ 2.2 million, and $1. 8 million and the related total income tax benefits of $1. 0 million, $ 1.1 million, and $0.9 million in 2017, 2016 and 2015, respectively. In 2017, 2016 and 2015, cash received from option exercises and share issuances under our plans was $0.7 million, $ 0.5 million and $ 1.1 million, respectively. The actual tax benefit realized in 2017, 2016 and 2015 for the tax deductions from option exercises totaled $0.0 million, $0.0 million and $0.4 million, respectively. 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 445,740 and 0 shares under this program in 2017 and 2016, respectively. As of December 30, 2017, the cumulative total authorized shares available for repurchase is approximately 2.7 million shares.

RETIREMENT PLANS	J. RETIREMENT PLANS We have a profit sharing and 401(k) plan for the benefit of substantially all of our employees, excluding the employees of certain wholly-owned subsidiaries. Amounts contributed to the plan are made at the discretion of the Board of Directors. We matched 25% of employee contributions in 2017, 2016, and 2015, on a discretionary basis, totaling $4.8 million, $ 4.4 million, and $2.4 million respectively. The basis for matching contributions may not exceed the lesser of 6% of the employee’s annual compensation or the IRS limitation. On July 14, 2011, the compensation committee of the board of directors approved a retirement plan for certain officers of the Company (who have at least 20 years of service with the Company and at least 10 years of service as an officer) whereby we will pay, upon retirement, benefits totaling 150% of the officer’s highest base salary in the three years immediately preceding separation from service plus health care benefits for a specified period of time if certain eligibility requirements are met. Approximately $ 7.8 million and $6.5 million are accrued in “Other Liabilities” for this plan at December 30, 2017 and December 31, 2016, respectively.

The Company also has a $0.2 million federal alternative minimum tax credit which it expects to be refunded. The NOL and credit carryforwards expire as follows: Net Operating Losses Tax Credits U.S. State Foreign U.S. State 2017 – 2021 $ — $ 356 $ 2,106 $ — $ 270 2022 - 2026 — 391 243 — 233 2027 - 2031 — 605 156 — — 2032 - 2036 3,431 804 — — — Thereafter — 419 81 — — Total $ 3,431 $ 2,575 $ 2,586 $ — $ 503 As of December 30, 2017, we believe that it is more likely than not that the benefit from certain state and foreign NOL carryforwards as well as certain state tax credit carryforwards will not be realized. In recognition of this risk, we have provided a valuation allowance against various NOL and tax credit carryforwards. Furthermore, there is a valuation allowance of $0.5 million against a capital loss carryforward we have for a wholly-owned subsidiary, UFP Canada, Inc. Based upon the business activity and the nature of the assets of this subsidiary, our ability to realize a future benefit from this carryforward is doubtful. The capital loss has an unlimited carryforward and therefore will not expire unless there is a change in control of the subsidiary. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the ”Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code that will affect 2017, including, but not limited to, (1) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years and (2) bonus depreciation that will allow for full expensing of qualified property. The Tax Act also established new tax laws that will affect 2018, including, but not limited to, (1) reduction of the U.S. federal corporate tax rate; (2) elimination of the corporate alternative minimum tax (AMT); (3) the creation of the base erosion anti-abuse tax (BEAT), a new minimum tax: (4) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (5) a new provision designed to tax global intangible low-taxed income (GILTI), which allows for the possibility of using foreign tax credits (FTCs) and a deduction of up to 50 percent to offset the income tax liability (subject to some limitations); (6) a new limitation on deductible interest expense; (7) the repeal of the domestic production activity deduction; (8) limitations on the deductibility of certain executive compensation; (9) limitations on the use of FTCs to reduce the U.S. income tax liability; and (10) limitations on net operating losses (NOLs) generated after December 31, 2017, to 80 percent of taxable income. The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. In connection with our initial analysis of the impact of the Tax Act, we have recorded a discrete net tax benefit of $6.1 million in the period ending December 30, 2017. This net benefit primarily consists of (1) a net benefit for the corporate rate reduction of $8.2 million; (2) a net expense for the write-down of deferred tax assets for stock based compensation that will no longer be deductible for $1.9 million; and (3) a net expense for the transition tax of $0.2 million. For various reasons that are discussed more fully below, we have not completed our accounting for the income tax effects of certain elements of the Tax Act. If we were able to make reasonable estimates of the effects of elements for which our analysis is not yet complete, we recorded provisional adjustments. If we were not yet able to make reasonable estimates of the impact of certain elements, we have not recorded any adjustments related to those elements and have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. Our accounting for the following elements of the Tax Act is incomplete. However, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments as follows: Reduction of U.S. federal corporate tax rate: The Tax Act reduces the corporate tax rate to 21 percent, effective January 1, 2018. For certain of our DTAs and DTLs, we have recorded a provisional decrease of $13.6 million and $21.8 million, respectively, with a corresponding net adjustment of deferred income tax benefit of $8.2 million for the year ended December 30, 2017. While we are able to make a reasonable estimate of the impact of the reduction in corporate rate, it may be affected by other analysis related to the Tax Act, including, but not limited to, our calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences. Deemed Repatriation Transition Tax: The Deemed Repatriation Transition Tax (Transition Tax) is a tax on previously untaxed accumulated and current earnings and profits (E&P) of certain of our foreign subsidiaries. To determine the amount of the Transition Tax, we must determine, in addition to other factors, the amount of post-1986 E&P of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. We are able to make a reasonable estimate of the Transition Tax and recorded a provisional Transition Tax obligation comprised of $6.3 million tax on foreign earnings and offset by FTCs of $6.1 million. However, we are continuing to gather additional information to more precisely compute the amount of the Transition Tax for any potential state tax effects and we are still evaluating the remaining outside basis differences not closed by the imposition of the transition tax. Tentatively, no changes were made to our ASC 740-30 assertion. Cost recovery : While we have not yet completed all of the computations necessary or completed an inventory of our 2017 expenditures that qualify for immediate expensing, we have recorded a provisional benefit of $0.1 million based on our current intent to fully expense all qualifying expenditures. This resulted in a decrease of approximately $0.3 million to our current income tax payable and a corresponding increase in our DTLs of approximately $0.2 million (after considering the effects of the reduction in income tax rates). Our accounting for the following elements of the Tax Act is incomplete, and we were not yet able to make reasonable estimates of the effects. Therefore, no provisional adjustments were recorded. Global intangible low taxed income (GILTI): The Tax Act creates a new requirement that certain income (i.e., GILTI) earned by controlled foreign corporations (CFCs) must be included currently in the gross income of the CFCs’ U.S. shareholder. GILTI is the excess of the shareholder’s “net CFC tested income” over the net deemed tangible income return, which is currently defined as the excess of (1) 10 percent of the aggregate of the U.S. shareholder’s pro rata share of the qualified business asset investment of each CFC with respect to which it is a U.S. shareholder over (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income. Because of the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether we expect to have future U.S. inclusions in taxable income related to GILTI depends on not only our current structure and estimated future results of global operations but also our intent and ability to modify our structure and/or our business, we are not yet able to reasonably estimate the effect of the provision of the Tax Act. Therefore, we have not made any adjustments related to potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI. Valuation allowances: The company must assess whether valuation allowances assessments are affected by various aspects of the Tax Act (e.g., deemed repatriation of deferred foreign income and the effects on state NOLs, GILTI inclusions, new categories of FTCs). Since, as discussed herein, the company has recorded no amounts related to certain portions of the Tax Act, any corresponding determination of the need for or change in a valuation allowance has not be completed and no changes to valuation allowances as a result of the Tax Act have been recorded. The remaining provisions of the Tax Act, as listed above, became effective on January 1, 2018 and did not require accounting treatment for the year-ended December 30, 2017. We are currently analyzing the impact of these provisions.

ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES
ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES	L. 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): 2017 2016 2015 Gross unrecognized tax benefits beginning of year $ 3,381 $ 2,209 $ 1,793 Increase in tax positions for prior years 4 243 — Increase in tax positions due to acquisitions — 362 — Increase in tax positions for current year 1,107 905 754 Settlements with taxing authorities (2) (32) — Lapse in statute of limitations (490) (306) (338) Gross unrecognized tax benefits end of year $ 4,000 $ 3,381 $ 2,209 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 .7 million, $0.6 million, and $0.2 million at December 30, 2017, December 31, 2016, and December 26, 2015, 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 2014. 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 is $0.7 million.

COMMITMENTS, CONTINGENCIES, AND GUARANTEES
COMMITMENTS, CONTINGENCIES, AND GUARANTEES	M. 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 $3.0 million and $3.6 million on December 30, 2017 and December 31, 2016, respectively, 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 a 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 approximat e $0. 2 million. As a result, this amount is recorded in other long-term liabilities on December 30, 2017. 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 2014, two Company employees were terminated for violating the Company’s Code of Business Conduct and Ethics. In May 2015, those ex-employees were indicted by the grand jury. In April 2016, one of the two former employees pled guilty to four of the charges included in the indictment. In May 2016, the other former employee was found guilty by a jury on four of the charges included in the indictment. The Company has not been named as a target and continues to cooperate with the US Attorney’s Office in this matter. Based upon prior communications with the US Attorney’s Office, we do not believe that the resolution of this matter will have a material adverse impact on our financial condition or the results of our operations. In addition, on December 30, 2017, we were parties either as plaintiff or 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 30, 2017, we had outstanding purchase commitments on commenced capital projects of approximately $7.7 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 that 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 30, 2017, we had approximately $1.4 million in outstanding payment and performance bonds for open projects. We had approximately $ 7.6 million in payment and performance bonds outstanding for completed projects which are still under warranty. On December 30, 2017 we had outstanding letters of credit totaling $26.5 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 $16. 7 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 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. We did not enter into any new guarantee arrangements during 2017 which would require us to recognize a liability on our balance sheet.

SEGMENT REPORTING
SEGMENT REPORTING	N. 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, Europe, Asia and Australia, 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 our North, South, West, and International divisions. The exceptions to this geographic reporting and management structure are (a) the Company’s Alternative Materials Division, which offers a portfolio of non-wood products and distributes those products nation-wide and is accounted for as a reporting unit within the All Other segment, (b) the Company’s distribution unit (referred to as UFPD) which distributes a variety of products to the manufactured housing industry and is accounted for as a reporting unit within the North segment, and (c) idX division, which designs, manufactures, and installs customized interior fixtures and is accounted for within the All Other 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
PRINCIPLES OF CONSOLIDATION	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 SUBSIDIAIRIES	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	FISCAL YEAR Our fiscal year is a 52 or 53 week period, ending on the last Saturday of December. Unless otherwise stated, references to 2017, 2016, and 2015 relate to the fiscal years ended December 30, 2017, December 31, 2016, and December 26, 2015, respectively. Fiscal year 2016 was comprised of 53 weeks, which contributed an additional $ 60 million in sales in 2016 compared to fiscal years 2017 and 2015, which were comprised of 52 weeks.
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. Restricted cash consists of amounts required to be held for loss funding totaling $0.5 million and $0.4 million as of December 30, 2017 and December 31, 2016, respectively. In November 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2016-18, “Statement of Cash Flows (Topic 230)” (ASU 2016-18). Under ASU 2016-18, an entity will be required to explain changes in the statement of cash flows during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this update should be applied using retrospective transition method to each period presented. Companies are required to adopt the new standard for fiscal years beginning after December 15, 2017. Early adoption of ASU 2016-18 is permitted, including adoption in an interim period. The Company has early adopted this standard during the first quarter of 2017.
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	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): Additions Charged to Beginning Costs and Ending Balance Expenses Deductions* Balance Year Ended December 30,2017: Allowance for possible losses on accounts receivable $ 2,845 $ 28,102 $ (28,523) $ 2,424 Year Ended December 31, 2016: Allowance for possible losses on accounts receivable $ 2,672 $ 28,405 $ (28,232) $ 2,845 Year Ended December 26, 2015: Allowance for possible losses on accounts receivable $ 2,390 $ 20,538 $ (20,256) $ 2,672 * 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 $ 4.8 million and $6.0 million as of December 30, 2017 and December 31, 2016, respectively. All amounts are expected to be collected within 18 months. Concentration of accounts receivable related to our largest customer totaled $55.9 million and $34.0 million as of December 30, 2017 and December 31, 2016, respectively.
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. We have inventory on consignment at customer locations valued at $14.8 million as of December 30, 2017 and $12.2 million as of December 31, 2016.
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. 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	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.
LEASES	LEASES In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2016‑02, “Leases (Topic 842)” (ASU 2016‑02). Under ASU 2016‑02, an entity will be required to recognize assets and liabilities for the rights and obligations created by leases on the entity’s balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016‑02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity’s leases. Companies are required to adopt the new standard for annual and interim periods beginning after December 15, 2018. Early adoption of ASU 2016‑02 is permitted. The FASB has tentatively decided to amend certain aspects of its new leasing standard in an attempt to provide a relief from implementation costs. Specifically, entities may elect not to restate their comparative periods in the period of adoption when transitioning to the new standard. The Company plans to continue to evaluate the effect of the new leasing guidance in 2018; therefore, the quantitative impact has not yet been determined however the Company anticipates only a balance sheet impact.
GOODWILL	GOODWILL Our annual testing date for evaluating goodwill and indefinite-lived intangible asset impairment is 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.
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 company, Ardellis Insurance Ltd.(“Ardellis”), was incorporated on April 21, 2001 under the laws of Bermuda and is licensed as a Class 3A insurer under the Insurance Act 1978 of Bermuda. On April 14, 2017 the U.S. Branch of Ardellis Insurance Ltd. was granted its Certificate of Authority to transact property and casualty insurance lines as an admitted carrier in the State of Michigan. 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 30, 2017 and December 31, 2016. 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 30, 2017, Ardellis had 30 such contracts in place. Reserves associated with these contracts were $3.4 million at December 30, 2017 and $2.5 million at December 31, 2016, 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.
REVENUE RECOGNITION	REVENUE RECOGNITION On May 28, 2014, the FASB issued ASU No. 2014‑09 (Accounting Standard Codification 606), Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. The Company is currently finalizing its evaluation of the impact of adopting this new guidance, which is not expected to materially impact the Company's financial condition or results of operations. The five-step model has been applied to existing contracts with customers, and based upon this review, the Company does not expect the adoption of ASU 2014-09 to have a material quantitative impact on its consolidated financial statements, as the timing of revenue recognition for product sales will continue to occur at the point of shipment. Other types of revenue, such as installation and framing, which are immaterial to our total revenue, will continue to be recognized over the appropriate period of time. As required by the standard, the Company expects to make additional disclosures related to the nature, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company will adopt this standard in the first quarter of fiscal year 2018 using the modified retrospective. 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 30, 2017 and December 31, 2016 which are included in other current assets and other accrued liabilities, respectively (in thousands): December 30, December 31, 2017 2016 Cost and Earnings in Excess of Billings $ 5,005 $ 2,573 Billings in Excess of Cost and Earnings 4,435 4,748
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.
EARNINGS PER SHARE	EARNINGS PER SHARE The computation of earnings per share (“EPS”) is as follows (in thousands), which incorporate the retroactive effect of the Company’s 3 for 1 stock split: December 30, December 31, December 26, 2017 2016 2015 Numerator: Net earnings attributable to controlling interest $ 119,512 $ 101,179 $ 80,595 Adjustment for earnings allocated to non-vested restricted common stock (2,225) (1,595) (1,059) Net earnings for calculating EPS $ 117,287 $ 99,584 $ 79,536 Denominator: Weighted average shares outstanding 61,416 61,089 60,552 Adjustment for non-vested restricted common stock (1,143) (963) (795) Shares for calculating basic EPS 60,273 60,126 59,757 Effect of dilutive stock options 90 99 108 Shares for calculating diluted EPS 60,363 60,225 59,865 Net earnings per share: Basic $ 1.95 $ 1.66 $ 1.33 Diluted $ 1.94 $ 1.65 $ 1.33 No options were excluded from the computation of diluted EPS for 2017, 2016, or 2015.
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.
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, Europe, Asia and Australia, 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 our North, South, West, and International divisions. The exceptions to this geographic reporting and management structure are (a) the Company’s Alternative Materials Division, which offers a portfolio of non-wood products and distributes those products nation-wide and is accounted for as a reporting unit within the All Other segment, (b) the Company’s distribution unit (referred to as UFPD) which distributes a variety of products to the manufactured housing industry and is accounted for as a reporting unit within the North segment, and (c) idX division, which designs, manufactures, and installs customized interior fixtures and is accounted for within the All Other 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.
