Basis of Presentation and Summary of Significant Accounting Policies

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Organization and Ownership Structure — Atkore International Group Inc. (the "Company", "Atkore" or "AIG") is a leading manufacturer of Electrical Raceway products primarily for the non-residential construction and renovation markets and Mechanical Products & Solutions ("MP&S") for the construction and industrial markets. Electrical Raceway products form the critical infrastructure that enables the deployment, isolation and protection of a structure's electrical circuitry from the original power source to the final outlet. MP&S frame, support and secure component parts in a broad range of structures, equipment and systems in electrical, industrial and construction applications.

Atkore was incorporated in the State of Delaware on November 4, 2010. Atkore is the sole stockholder of Atkore International Holdings Inc. ("AIH"), which in turn is the sole stockholder of Atkore International, Inc. ("AII").

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of the Company included herein have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These unaudited condensed consolidated financial statements have been prepared in accordance with the Company's accounting policies and on the same basis as those financial statements included in the Company's latest Annual Report on Form 10-K for the year ended September 30, 2019, filed with the U.S. Securities and Exchange Commission (the "SEC") on November 22, 2019, and should be read in conjunction with those consolidated financial statements and the notes thereto. Certain information and disclosures normally included in the Company's annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC.

The unaudited condensed consolidated financial statements include the assets and liabilities used in operating the Company's business. All intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or disposed of are included in the unaudited condensed consolidated financial statements from the effective date of acquisition or up to the date of disposal.

These statements include all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. The results reported in these unaudited condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year.

Fiscal Periods — The Company has a fiscal year that ends on September 30. It is the Company's practice to establish quarterly closings using a 4-5-4 calendar. The Company's fiscal quarters end on the last Friday in December, March and June.

Use of Estimates — The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclose contingent assets and liabilities at the date of the condensed consolidated financial statements and report the associated amounts of revenues and expenses. Actual results could differ materially from these estimates.

Recent Accounting Pronouncements

A summary of recently adopted accounting guidance is as follows. Adoption dates are on the first day of the fiscal year indicated below, unless otherwise specified.

ASU	Description of ASU	Impact to Atkore	Note	Adoption Date
2016-02 Leases (Topic 842)	The Accounting Standards Update ("ASU") requires companies to use a "right of use" lease model that assumes that each lease creates an asset (the lessee's right to use the leased asset) and a liability (the future rent payment obligations), which should be reflected on a lessee's balance sheet to fairly represent the lease transaction and the lessee's related financial obligations with terms of more than 12 months.	The Company adopted the guidance in the first quarter of 2020 using the modified retrospective method. See Note 2, "Leases" for further detail.	2	2020

A summary of accounting guidance not yet adopted is as follows. Effective dates are on the first day of the fiscal year indicated below, unless otherwise specified.

ASU	Description of ASU	Impact to Atkore	Effective Date
2016-13 Financial Instruments - Credit Losses (Topic 326)	The ASU adds to U.S. GAAP an impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses.	Under evaluation.	2021
2018-14 Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans	The ASU amends Accounting Standards Codification ("ASC") 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans.	Under evaluation.	2021
2019-12 Income Tax	The ASU amends ASC 740 to simplify the accounting for various topics related to income taxes.	Under evaluation.	2021
2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (issued March 12, 2020)	The ASU addresses constituents’ concerns about certain accounting consequences that could result from the global markets’ anticipated transition away from the use of the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates.	Under evaluation.	2022
