Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of BlueLinx Holdings Inc. and its wholly owned subsidiaries (the “Company”). All intercompany accounts have been eliminated in consolidation. These financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K together with Amendment No. 1 to the Annual Report on Form 10-K/A (the “Annual Report on Form 10-K”) for the year ended January 3, 2015, as filed with the Securities and Exchange Commission.

New Accounting Standards

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, Inventory. The ASU requires entities that measure inventory using methods including the average cost method to measure inventory at the lower of cost and net realizable value. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of these provisions.

In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest. The ASU requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts or premiums. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. Early adoption is permitted. We do not expect that the adoption of these provisions will have a material effect on our consolidated financial statements.

In April 2015, the FASB issued ASU 2015-04, Compensation - Retirement Benefits. For entities with a fiscal year-end that does not coincide with a month-end, the ASU permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. ASU 2015-04 is effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. We plan to continue measuring the defined benefit plan assets and obligations at our fiscal year-end date.

In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software. The ASU requires that entities with a cloud computing arrangement that includes a software license, account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the entity should account for the arrangement as a service contract. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. Early adoption is permitted. We do not expect that the adoption of these provisions will have a material effect on our consolidated financial statements.

Reclassifications

Certain amounts in the prior years’ consolidated financial statements and notes have been revised to conform to the current year presentation. During fiscal 2015, we have separately detailed the “Pension Benefit Obligation”, which historically had been presented as “Other non-current liabilities” in the Condensed Consolidated Balance Sheets. To conform the historical presentation to the current presentation, we have separately detailed the “Pension Benefit Obligation” in prior periods from “Other non-current liabilities” in the Condensed Consolidated Balance Sheets.

Additionally, during fiscal 2015, we reclassified certain amounts, which historically had been presented as “Debt financing costs” to “Borrowings from the revolving credit facilities” in cash flows from financing activities. To conform the historical presentation to the current presentation, we reclassified similar items in prior periods from “Debt financing costs” to “Borrowings from the revolving credit facilities” in cash flows from financing activities.

Also, during fiscal 2015, we reclassified certain amounts, which historically had been presented as “Selling, general, and administrative” to “Gains from sales of property” in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). To conform the historical presentation to the current presentation, we reclassified similar items in prior periods from “Selling, general, and administrative” to “Gains from sales of property” in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
