NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(dollars and shares in thousands, except per share data)

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.

7

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

2. LEASES

On October 1, 2019, we adopted ASC Topic 842 using the modified retrospective transition method. Topic 842 requires the recognition of lease assets and liabilities for operating leases, in addition to the finance lease assets and liabilities previously recorded on our condensed consolidated balance sheets. Beginning on October 1, 2019, our condensed consolidated financial statements are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. The modified retrospective transition method required the cumulative effect, if any, of initially applying the guidance to be recognized as an adjustment to our accumulated deficit as of our adoption date. As a result of adopting Topic 842, we recognized additional operating lease assets and liabilities of $45,519 and $46,941 as of October 1, 2019. The discount rate primarily used to calculate that adjustment was the Company's incremental borrowing rate as of the adoption date, October 1, 2019, as a rate implicit in most contracts was not readily determinable. The Company recorded a cumulative effect adjustment of $1,053 to accumulated deficit, net of tax, as a result of the adoption.

The Company elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed us to carry forward prior conclusions about lease identification, classification and initial direct costs for leases entered into prior to adoption of Topic 842. Additionally, for leases with a term of 12 months or less, the Company elected the short-term lease exemption, which allowed us to not recognize right-of-use assets ("ROU") or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future. Leases with an initial term of 12 months or less are classified as short-term leases and are not recorded on the condensed consolidated balance sheets. The lease expense for short-term leases is recognized on a straight-line basis over the lease term.

The Company engages in leasing transactions to meet the needs of the business. The Company leases certain warehouses and distribution centers, office space, forklifts, vehicles and other machinery and equipment. The determination to lease, rather

8

than purchase, an asset is primarily contingent upon capital requirements, duration of the forecasted business investment, and asset availability.

The Company determines if an arrangement is a lease at inception and all arrangements deemed to be leases are subject to an assessment to determine the classification between finance and operating leases. The Company's significant assumptions and judgments in determining whether a contract is or contains a lease include establishing whether the supplier has the ability to use other assets to fulfill its service or whether the terms of the agreement enable the Company to control the use of a dedicated property, plant and equipment asset during the contract term. In the majority of the Company's contracts where it must identify whether a lease is present, it is readily determinable that the Company controls the use of the assets and obtains substantially all of the economic benefit during the term of the contract. In those contracts where identification is not readily determinable, the Company has determined that the supplier has either the ability to use another asset to provide the service or the terms of the contract give the supplier the rights to operate the asset at its discretion during the term of the contract, in which case the arrangement would not constitute a lease.

Right-of-use assets and lease obligations are recognized based on the present value of the future minimum lease payments over the lease term as of the commencement date. The Company’s lease agreements have terms that include both lease and non-lease components. Lease component fees are included in the present value of future minimum lease payments. Conversely, non-lease components are not subject to capitalization and are expensed as incurred. Per Topic 842, the contractual interest rate is used to calculate the present value of the future minimum lease payments. However, the majority of the Company’s leases do not provide an implicit rate. Therefore, the Company's significant assumption and judgments in determining the discount rate include determining the incremental borrowing rate. The Company’s incremental borrowing rates are based on the term of the lease, the economic environment of the lease and the effect of collateralization. The valuation of the ROU asset also includes lease payments made in advance of the lease commencement date and initial direct costs incurred to secure the lease and is reduced for lease incentives. The lease terms include options to extend or terminate the lease when it is reasonably certain the Company will exercise the options.

The Company has certain leasing agreements, related to leased vehicles available to our sales personnel, that contain guaranteed residual value terms, which are not expected to be triggered. The Company’s leasing portfolio does not contain any material restrictive covenants.

3. REVENUE FROM CONTRACTS WITH CUSTOMERS

The Company’s revenue arrangements primarily consist of a single performance obligation to transfer promised goods which is satisfied at a point in time when title, risks and rewards of ownership, and subsequently control have transferred to the customer. This generally occurs when the product is shipped to the customer, with an immaterial amount of transactions in which control transfers upon delivery. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations.

The Company has certain arrangements that require it to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of products to be returned. The Company principally relies on historical experience, specific customer agreements, and anticipated future trends to estimate these amounts at the time of sale and to reduce the transaction price. These arrangements include sales discounts and allowances, volume rebates, and returned goods.

The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. The Company also expenses costs incurred to obtain a contract, primarily sales commissions, as all obligations will be settled in less than one year.

The Company typically receives payment 30 to 60 days from the point it has satisfied the related performance obligation. See Note 18, ''Segment Information'' for revenue disaggregated by geography and product categories.

4. ACQUISITIONS

From time to time, the Company enters into strategic acquisitions in an effort to better service existing customers and to attain new customers.

On August 21, 2019, Atkore Plastic Pipe Corporation, a wholly-owned subsidiary of the Company acquired the assets of Rocky Mountain Pipe ("Cor-Tek"), a manufacturer of PVC conduit for electrical applications, and considered a leading innovator in cellular core extrusion technology for a purchase price of $14,835. In connection with this acquisition, the Company recorded a bargain purchase gain of $7,384 within other income, net during the fourth quarter of fiscal 2019 in the Statement of Operations. The Company believes that it was able to acquire the net assets of Cor-Tek for less than fair value as a result of Cor-Tek’s financial difficulties.

11

On August 12, 2019, Unistrut Limited, a wholly-owned subsidiary of the Company, acquired Flytec Systems Ltd. and its parent holding company, Modern Associates Ltd., (collectively "Flytec"), a manufacturer of metal surface trunking, including IP4X, perimeter systems, pedestal boxes, as well as underfloor installations and industrial floor trunking. The purchase price was immaterial to the Company.

On June 3, 2019, AFC Cable Systems, Inc., a wholly-owned subsidiary of the Company acquired the assets of United Structural Products, LLC. ("U.S. Tray"), a manufacturer of welded aluminum and engineered-to-order cable trays for a purchase price of $25,507, net of cash received. As a result of the acquisition, the Company recognized $7,295 of goodwill, $14,800 of identifiable intangible assets and $3,412 of working capital and other net other tangible assets.

On October 1, 2018, Allied Luxembourg S.a.r.l, a wholly-owned subsidiary of the Company acquired all of the outstanding stock of Vergokan International NV ("Vergokan") for a purchase price of $57,899, net of cash received. Vergokan is a leading manufacturer of cable tray and cable ladder systems, underfloor installations and industrial floor trunking that serves industrial, power and energy, commercial and infrastructure sectors in more than 45 countries. This transaction provides Atkore with an expanded presence in Western Europe and strengthens the Company's electrical portfolio of cable management products within the Electrical Raceway segment.

All the above acquisitions were funded with cash on hand. The condensed consolidated financial statements include the results of the acquired companies from the acquisition date. Due to the immaterial nature of these acquisitions, both individually, and in the aggregate, the Company did not include the full year pro forma results of operations for the acquisition year or previous years.

The purchase price was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values. The following table summarizes the Level 3 fair values assigned to the net assets acquired and liabilities assumed as of the acquisition date for fiscal 2019:

8. INCOME TAXES    

For the three months ended December 27, 2019 and December 28, 2018, the Company's effective tax rate attributable to income before income taxes was 17.4% and 23.2%, respectively. For the three months ended December 27, 2019 and December 28, 2018, the Company's income tax expense was $7,340 and $8,154 respectively. The decrease in the current period effective tax rate was primarily due to an increase in the excess tax benefit associated with stock compensation.

A valuation allowance has been recorded against certain net operating losses in certain foreign jurisdictions.  A valuation allowance is recorded when it is determined to be more likely than not that these assets will not be fully realized in the foreseeable future. The realization of deferred tax assets is dependent upon whether the Company can generate future taxable income in the appropriate character and jurisdiction to utilize the assets. The amount of the deferred tax assets considered realizable is subject to adjustment in future periods.

The Company recognizes the benefits of uncertain tax positions taken or expected to be taken in tax returns in the provision for income taxes only for those positions that we have determined are more likely than not to be realized upon examination. We record interest and penalties related to unrecognized tax benefits as a component of income tax expense. For the three months ended December 27, 2019 there was no change in the balance of unrecognized tax benefits.

For the three months ended December 27, 2019, the Company made no additional provision for U.S. or non-U.S. income taxes for unrecognized deferred tax liabilities for temporary differences related to basis differences in investments in subsidiaries, as the investments are essentially permanent in duration.

9. EARNINGS PER SHARE

The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating securities as if all of the net earnings for the period had been distributed. The Company's participating securities consist of share-based payment awards that contain a non-forfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common stockholders.

Basic earnings per common share excludes dilution and is calculated by dividing the net earnings allocable to common stock by the weighted-average number of common stock outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocated to common stock by the weighted-average number of shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.

14

The following table sets forth the computation of basic and diluted earnings per share:

	Three months ended
(in thousands, except per share data)	December 27, 2019		December 28, 2018

Basic earnings per share	$	0.72	$	0.56
Diluted earnings per share	$	0.71	$	0.54
(1) Stock options to purchase approximately 0.1 million and 0.6 million shares of common stock were outstanding during the three months ended December 27, 2019 and December 28, 2018, respectively, but were not included in the calculation of diluted earnings per share as the impact of these options would have been anti-dilutive.

11. INVENTORIES, NET

A majority of the Company's inventories are recorded at the lower of cost (primarily last in, first out, or "LIFO") or market. Approximately 72% and 72% of the Company's inventories were valued at the lower of LIFO cost or market at December 27, 2019 and September 30, 2019, respectively. Interim LIFO determinations, including those at December 27, 2019, are based on management's estimates of future inventory levels and costs for the remainder of the current fiscal year.

13. GOODWILL AND INTANGIBLE ASSETS

Changes in the carrying amount of goodwill are as follows:    

(in thousands)	Electrical Raceway		Mechanical Products & Solutions		Total
Balance as of October 1, 2019	$	149,668	$	36,563	$	186,231
Exchange rate effects	1,874		—		1,874
Balance as of December 27, 2019	$	151,542	$	36,563	$	188,105

Goodwill balances as of October 1, 2019 and December 27, 2019 include $3,924 and $43,000 of accumulated impairment losses within the Electrical Raceway and MP&S segments, respectively.

The Company assesses the recoverability of goodwill and indefinite-lived trade names on an annual basis in accordance with ASC 350, "Intangibles - Goodwill and Other." The measurement date is the first day of the fourth fiscal quarter, or more frequently, if events or circumstances indicate that it is more likely than not that the fair value of a reporting unit or the respective indefinite-lived trade name is less than the carrying value.

The following table provides the gross carrying value, accumulated amortization and net carrying value for each major class of intangible assets:

		December 27, 2019							September 30, 2019

The asset-based credit facility (the "ABL Credit Facility") has aggregate commitments of $325,000 and is guaranteed by AIH and the U.S. operating companies owned by AII. AII's availability under the ABL Credit Facility was $282,628 and $301,882 as of December 27, 2019 and September 30, 2019, respectively.

15. FAIR VALUE MEASUREMENTS

Certain assets and liabilities are required to be recorded at fair value on a recurring basis.

The Company uses forward currency contracts to hedge the effects of foreign exchange relating to certain of the Company’s intercompany balances denominated in a foreign currency. These derivative instruments are not formally designated as hedges by the Company and the terms of these instruments range at inception from six months to five years. Short-term forward currency contracts are recorded in either other current assets or other current liabilities and long-term forward currency contracts are recorded in either other long-term assets or other long-term liabilities in the condensed consolidated balance sheet. The fair value gains and losses are included in other income, net within the condensed consolidated statements of operations. See Note 7, ''Other Income, net'' for further detail.

The total notional amounts of undesignated forward currency contracts were £45.0 million and £45.0 million as of December 27, 2019 and September 30, 2019, respectively. Cash flows associated with derivative financial instruments are recognized in the operating section of the condensed consolidated statements of cash flows. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

The following table presents the Company's assets and liabilities measured at fair value:

	December 27, 2019						September 30, 2019
(in thousands)	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
Assets
Cash equivalents	$	111,422	$	—	$	—	$	72,132	$	—	$	—
Forward currency contracts	—		297		—		—		3,420		—

The Company's remaining financial instruments consist primarily of cash, accounts receivable and accounts payable whose carrying value approximate their fair value due to their short-term nature.

The estimated fair value of financial instruments not carried at fair value in the condensed consolidated balance sheets were as follows:

	December 27, 2019				September 30, 2019
(in thousands)	Carrying Value		Fair Value		Carrying Value		Fair Value
First Lien Term Loan Facility due December 22, 2023	$	852,120	$	854,677	$	852,120	$	853,543

In determining the approximate fair value of its long-term debt, the Company used the trading values among financial institutions, and these values fall within Level 2 of the fair value hierarchy. The carrying value of the ABL Credit Facility approximates fair value due to it being a market-linked variable rate debt.

16. COMMITMENTS AND CONTINGENCIES

The Company has obligations related to commitments to purchase certain goods. As of December 27, 2019, such obligations were $211,046 for the rest of fiscal year 2020 and $976 for fiscal year 2021 and beyond. These amounts represent open purchase orders for materials used in production.

Legal Contingencies —The Company is a defendant in a number of pending legal proceedings, some of which were inherited from its former parent, Tyco International Ltd. ("Tyco"), including certain product liability claims. Several lawsuits have been filed against the Company and the Company has also received other claim demand letters alleging that the Company's anti-microbial coated steel sprinkler pipe, which the Company has not manufactured or sold for several years, is incompatible with chlorinated polyvinyl chloride and caused stress cracking in such pipe manufactured by third parties when installed together in the same sprinkler system, which the Company refers to collectively as the "Special Products Claims." After an analysis of claims experience, the Company reserved its best estimate of the probable and reasonably estimable losses related to these matters. The Company's total product liability reserves for Special Products Claims and other product liability matters were $2,577 and $2,424 as of December 27, 2019 and September 30, 2019, respectively. As of December 27, 2019, the Company believes that the range of reasonably possible losses for Special Products Claims and other product liabilities is between $1,000 and $8,000.

During fiscal 2019, Tyco and the Company agreed with a plaintiff to settle one Special Products Claim that was to go to trial.  The Company agreed to fund the total settlement in exchange for Tyco's agreement to cap the Company's Special Products Claim deductible at $12,000, as opposed to the $13,000 cap negotiated within the original indemnity agreement. In conjunction with the payment of that settlement, Tyco and the Company examined the Company's total Special Products Claim payments and agreed that with that settlement payment and payment of a few other legal fee invoices, all of which have now been paid, the Company had met its $12,000 deductible obligation related to these Special Products Claims. Tyco, now Johnson Controls, Inc. ("JCI"), has a contractual obligation to indemnify the Company in respect of all remaining and future claims of incompatibility between the Company's antimicrobial coated steel sprinkler pipe and CPVC pipe used in the same sprinkler system. Tyco has defended and indemnified the Company on Special Products Claims as required.

At this time, the Company does not expect the outcome of the Special Products Claims proceedings, either individually or in the aggregate, to have a material adverse effect on its business, financial condition, results of operations or cash flows, and the Company believes that its reserves are adequate for all remaining contingencies for Special Products Claims.

In addition to the matters discussed above, from time to time, the Company is subject to a number of disputes, administrative proceedings and other claims arising out of the ordinary conduct of the Company's business. These matters generally relate to disputes arising out of the use or installation of the Company's products, product liability litigation, contract disputes, patent infringement accusations, employment matters, personal injury claims and similar matters. On the basis of information currently available to the Company, it does not believe that existing proceedings and claims will have a material adverse effect on its business, financial condition, results of operations or cash flows. However, litigation is unpredictable, and the Company could incur judgments or enter into settlements for current or future claims that could adversely affect its business, financial condition, results of operations or cash flows.

17. GUARANTEES

The Company had outstanding letters of credit totaling $9,501 supporting workers' compensation and general liability insurance policies as of December 27, 2019. The Company also had surety bonds primarily related to performance guarantees on supply agreements and construction contracts, and payment of duties and taxes totaling $18,498 as of December 27, 2019.

In disposing of assets or businesses, the Company often provides representations, warranties and indemnities to cover various risks including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities, and unidentified tax liabilities and legal fees related to periods prior to disposition. The Company does not have the ability to estimate the potential liability from such indemnities because they relate to unknown conditions. However, the Company has no reason to believe that these uncertainties would have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.

In the normal course of business, the Company is liable for product performance and contract completion. In the opinion of management, such obligations will not have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.

19

18. SEGMENT INFORMATION

The Company has two operating segments, which are also its reportable segments. The Company's operating segments are organized based upon primary market channels and, in most instances, the end use of products.

Through its Electrical Raceway segment, the Company manufactures products that deploy, isolate and protect a structure's electrical circuitry from the original power source to the final outlet. These products, which include electrical conduit, armored cable, cable trays, mounting systems and fittings, are critical components of the electrical infrastructure for maintenance, repair and remodel markets. The vast majority of the Company's Electrical Raceway net sales are made to electrical distributors, who then serve electrical contractors and the Company considers both to be customers.

Through the MP&S segment, the Company provides products and services that frame, support and secure component parts in a broad range of structures, equipment and systems in electrical, industrial and construction applications. The Company's principal products in this segment are metal framing products and in-line galvanized mechanical tube. Through its metal framing business, the Company designs, manufactures and installs metal strut and fittings used to assemble mounting structures that support heavy equipment and electrical content in buildings and other structures.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is the sum of income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, restructuring charges, stock-based compensation, certain legal matters, transaction costs and other items, such as inventory reserves and adjustments, release of indemnified uncertain tax positions, and the impact of foreign exchange gains or losses.

Intersegment transactions primarily consist of product sales at designated transfer prices on an arm's-length basis. Gross profit earned and reported within the segment is eliminated in the Company's consolidated results. Certain manufacturing and distribution expenses are allocated between the segments on a pro rata basis due to the shared nature of activities. Recorded amounts represent a proportional amount of the quantity of product produced for each segment. Certain assets, such as machinery and equipment and facilities, are not allocated to each segment despite serving both segments. These shared assets are reported within the MP&S segment. We allocate certain corporate operating expenses that directly benefit our operating segments, such as insurance and information technology, on a basis that reasonably approximates an estimate of the use of these services.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following information should be read in conjunction with the unaudited condensed consolidated financial statements and related notes included in this report. The following discussion may contain forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in these forward- looking statements. Factors that could cause or contribute to these differences include those factors discussed below and included or referenced elsewhere in this report, particularly in the sections entitled "Forward-Looking Statements" and "Risk Factors".

Results of Operations

The results of operations for the three months ended December 27, 2019 and December 28, 2018 were as follows:

Volume	3.1	%
Average selling prices	(6.6	)%
Foreign exchange	(0.1	)%

Other	(0.1	)%
Net sales	(1.0	)%

Net sales decreased by $4.6 million, or 1.0%, to $447.4 million for the three months ended December 27, 2019, compared to $452.0 million for the three months ended December 28, 2018. The decrease is primarily attributed to $30.0 million of lower average selling prices resulting from lower commodity input costs of steel and resin. The decrease in net sales was partially offset by higher volume of $14.1 million primarily in the PVC electrical conduit and fittings product category sold within the Electrical Raceway segment, as well as, the mechanical pipe product category sold within the Mechanical Products & Solutions segment. Additionally, the decrease in net sales was partially offset by increased sales of $12.4 million from the acquisition of the assets of United Structural Products, LLC. ("US Tray") and Rocky Mountain Pipe ("Cor-Tek") and the acquisition of Flytec Systems Ltd. and its parent holding company, Modern Associates Ltd., in fiscal 2019 (together, the "2019 acquisitions").

Volume	3.3	%
Average input costs	(11.4	)%
Foreign exchange	(0.2	)%
Acquisitions	2.9	%
Other	2.1	%
Cost of sales	(3.3	)%

Cost of sales decreased by $11.2 million, or 3.3% to $330.6 million for the three months ended December 27, 2019 compared to $341.8 million for the three months ended December 28, 2018. The decrease was primarily due to the lower input costs of steel and resin of $38.9 million. The decrease was partially offset by higher volume of $11.4 million, incremental costs of $10.0 million due to the 2019 acquisitions, additional freight costs of $4.0 million and inventory adjustments related to changes in market prices of $2.0 million.

Selling, general and administrative

Selling, general and administrative expenses decreased by $0.2 million, or 0.3%, to $56.2 million for the three months ended December 27, 2019 compared to $56.4 million for the three months ended December 28, 2018. The decrease was primarily due to lower restructuring costs of $1.2 million and lower foreign exchange expense of $0.4 million, partially offset by $1.5 million of incremental costs resulting from fiscal 2019 acquisitions.

Intangible asset amortization

Intangible asset amortization expense decreased by $0.1 million, or 1.2%, to $8.1 million for the three months ended December 27, 2019 compared to $8.2 million for the three months ended December 28, 2018. The decrease in intangible asset amortization is primarily due to certain assets that reached the end of their amortized lives by the conclusion of fiscal 2019, partially offset by additional amortization resulting from fiscal 2019 acquisitions.

Interest expense, net

Interest expense, net decreased by $1.5 million, or 12.7% to $10.6 million for the three months ended December 27, 2019 compared to $12.2 million for the three months ended December 28, 2018. The decrease is primarily due to the Company's principal payments in fiscal 2019 resulting in a lower principal balance in fiscal 2020 from which interest expense was derived from.

Other income, net

Other income, net decreased by $1.4 million to $0.2 million for the three months ended December 27, 2019 compared to $1.6 million for the three months ended December 28, 2018 primarily due to losses from the Company's undesignated foreign currency derivative instruments partially offset by foreign exchange gains on intercompany loans.

Income tax expense

The Company's income tax rate decreased to 17.4% for the three months ended December 27, 2019 compared to 23.2% for the three months ended December 28, 2018. The decrease in the current period effective tax rate was primarily due to an increase in the excess tax benefit associated with stock compensation, which had a greater impact in fiscal 2020.

Segment results

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is the sum of income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, restructuring charges, stock-based compensation, certain legal matters, transaction costs and other items, such as inventory reserves and adjustments, release of indemnified uncertain tax positions, and the impact of foreign exchange gains or losses. We define segment Adjusted EBITDA Margin as segment Adjusted EBITDA as a percentage of segment Net sales.

Net sales decreased by $2.0 million, or 0.6%, to $341.4 million for the three months ended December 27, 2019 compared to $343.4 million for the three months ended December 28, 2018. The decrease is primarily attributed to the pass-through impact of lower average selling prices of $19.1 million resulting from lower commodity input costs of steel and resin. The decrease in net sales was partially offset by the 2019 acquisitions, which contributed $12.4 million in sales for the three months ended December 27, 2019. Additionally, the decrease in net sales was offset by $6.7 million in higher volume, primarily in the PVC electrical conduit and fittings product category.

Adjusted EBITDA

Adjusted EBITDA for the three months ended December 27, 2019 increased by $1.7 million, or 2.5%, to $70.2 million from $68.5 million for the three months ended December 28, 2018. Adjusted EBITDA margins increased to 20.6% for the three months ended December 27, 2019 compared to 19.9% for the three months ended December 28, 2018. The increase in Adjusted EBITDA was largely due to operational efficiencies, the contributions from the 2019 acquisitions, and incremental profit from higher volume.

Net sales decreased by $2.2 million, or 2.0%, for the three months ended December 27, 2019 to $106.7 million compared to $108.8 million for the three months ended December 28, 2018. The decrease is primarily attributed to the pass-through impact of lower average input costs of steel products of $10.8 million, partially offset by higher volume of $7.3 million primarily in the mechanical pipe product category.

Adjusted EBITDA

Adjusted EBITDA increased by $5.8 million, or 53.0%, to $16.7 million for the three months ended December 27, 2019 compared to $10.9 million for the three months ended December 28, 2018. Adjusted EBITDA margins increased to 15.6% for the three months ended December 27, 2019 compared to 10.0% for the three months ended December 28, 2018. Adjusted EBITDA increased primarily due to higher volume, pricing strategies and operational efficiencies.

Liquidity and Capital Resources

We believe we have sufficient liquidity to support our ongoing operations and to invest in future growth and create value for stockholders. Our cash and cash equivalents were $164.1 million as of December 27, 2019, of which $46.9 million was held at non-U.S. subsidiaries. Those cash balances at foreign subsidiaries may be subject to withholding or local country taxes if the Company's intention to permanently reinvest such income were to change and cash was repatriated to the United States.

In general, we require cash to fund working capital investments, acquisitions, capital expenditures, debt repayment, interest payments, taxes and share repurchases. We have access to the ABL Credit Facility to fund operational needs. As of December 27, 2019, there were no outstanding borrowings under the ABL Credit Facility and $9.5 million of letters of credit issued under the ABL Credit Facility. The borrowing base was estimated to be $292.1 million and approximately $282.6 million was available under the ABL Credit Facility as of December 27, 2019. Outstanding letters of credit count as utilization of the commitments under the ABL Credit Facility and reduce the amount available for borrowings.

The agreements governing the First Lien Term Loan Facility and the ABL Credit Facility (collectively, the "Credit Facilities") contain covenants that limit or restrict AII's ability to incur additional indebtedness, repurchase debt, incur liens, sell assets, make certain payments (including dividends) and enter into transactions with affiliates. AII has been in compliance with the covenants under the agreements for all periods presented.

We may from time to time repurchase our debt or take other steps to reduce our debt. These actions may include open market repurchases, negotiated repurchases or opportunistic refinancing of debt. The amount of debt, if any, that may be repurchased or refinanced will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations.

Our use of cash may fluctuate during the year and from year to year due to differences in demand and changes in economic conditions primarily related to the prices of commodities we purchase.

Capital expenditures have historically been necessary to expand and update the production capacity and improve the productivity of our manufacturing operations.

Our ongoing liquidity needs are expected to be funded by cash on hand, net cash provided by operating activities and, as required, borrowings under the ABL Credit Facility. We expect that cash provided from operations and available capacity under the ABL Credit Facility will provide sufficient funds to operate our business, make expected capital expenditures and meet our liquidity requirements for at least the next twelve months, including payment of interest and principal on our debt.

26

Limitations on Distributions and Dividends by Subsidiaries

AIG, AII, and AIH are each holding companies, and as such have no independent operations or material assets other than ownership of equity interests in their respective subsidiaries. Each company depends on its respective subsidiaries to distribute funds to it so that it may pay obligations and expenses, including satisfying obligations with respect to indebtedness. The ability of our subsidiaries to make distributions and dividends to us depends on their operating results, cash requirements and financial and general business conditions, as well as restrictions under the laws of our subsidiaries' jurisdictions.

The agreements governing the ABL Credit Facility significantly restrict the ability of our subsidiaries, including AII, to pay dividends, make loans or otherwise transfer assets from AII and, in turn, to us. Further, AII's subsidiaries are permitted under the terms of the ABL Credit Facility to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to AII and, in turn, to us. The First Lien Term Loan Facility requires AII to meet a certain consolidated coverage ratio on an incurrence basis in connection with additional indebtedness. The ABL Credit Facility contains limits on additional indebtedness based on various conditions for incurring the additional debt.

The table below summarizes cash flow information derived from our statements of cash flows for the periods indicated:

	Three months ended
(in thousands)	December 27, 2019			December 28, 2018
Cash flows provided by (used in):
Operating activities	$	52,173		$	40,277
Investing activities	(9,794		)	(64,925		)
Financing activities	(3,041		)	(25,176		)

Operating activities

During the three months ended December 27, 2019, the Company was provided $52.2 million by operating activities compared to $40.3 million during the three months ended December 28, 2018. The $11.9 million increase in cash provided was primarily due to higher gross profit, partially offset by lower cash flows from working capital.

Investing activities

During the three months ended December 27, 2019, the Company used $9.8 million in investing activities compared to $64.9 million during the three months ended December 28, 2018. The decrease in cash used in investing activities is primarily due the acquisition of Vergokan for $58.7 million during the three months ended December 28, 2018.

Financing Activities

During the three months ended December 27, 2019, the Company used $3.0 million in financing activities compared to $25.2 million used during the three months ended December 28, 2018. The decrease in cash used in financing activities is primarily due to $24.4 million of share repurchases during the three months ended December 28, 2018, compared to no share repurchases during the three months ended December 27, 2019.

• possible impairment of goodwill or other long-lived assets as a result of future triggering events, such as declines in our cash flow projections or customer demand;

• safety and labor risks associated with the manufacture and in the testing of our products;

• product liability, construction defect and warranty claims and litigation relating to our various products, as well as government inquiries and investigations, and consumer, employment, tort and other legal proceedings;

• our ability to protect our intellectual property and other material proprietary rights;

• risks inherent in doing business internationally;

• our inability to introduce new products effectively or implement our innovation strategies;

• the inability of our customers to pay off the credit lines extended to them by us in a timely manner and the negative impact on customer relations resulting from our collections efforts with respect to non-paying or slow-paying customers;

• the incurrence of liabilities and the issuance of additional debt or equity in connection with acquisitions, joint ventures or divestitures and the failure of indemnification provisions in our acquisition agreements to fully protect us from unexpected liabilities;

• failure to manage acquisitions successfully, including identifying, evaluating, and valuing acquisition targets and integrating acquired companies, businesses or assets;

• the incurrence of liabilities in connection with violations of the FCPA and similar foreign anti-corruption laws;

• the incurrence of additional expenses, increase in complexity of our supply chain and potential damage to our reputation with customers resulting from regulations related to "conflict minerals";

• disruptions or impediments to the receipt of sufficient raw materials resulting from various anti-terrorism security measures;

• restrictions contained in our debt agreements;

• failure to generate cash sufficient to pay the principal of, interest on, or other amounts due on our debt; and

• other risks and factors described in this report and from time to time in documents that we file with the SEC.

You should read this Quarterly Report on Form 10-Q completely and with the understanding that actual future results may be materially different from expectations. All forward-looking statements attributable to us or persons acting on our behalf that are made in this quarterly report are qualified in their entirety by these cautionary statements. These forward-looking statements are made only as of the date of this Quarterly Report on Form 10-Q, and we do not undertake any obligation, other than as may be required by law, to update or revise any forward-looking or cautionary statements to reflect changes in assumptions, the occurrence of events, unanticipated or otherwise, and changes in future operating results over time or otherwise.

Comparisons of results for current and any prior periods are not intended to express any future trends, or indications of future performance, unless expressed as such, and should only be viewed as historical data.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes to the quantitative and qualitative disclosures about market risks previously disclosed in our Annual Report on Form 10-K.

29

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of the end of the period covered by this report. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes to our internal control over financial reporting in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Fair Value Disclosures [Abstract]

Fair Value Measurements

15. FAIR VALUE MEASUREMENTS

Certain assets and liabilities are required to be recorded at fair value on a recurring basis.

The Company uses forward currency contracts to hedge the effects of foreign exchange relating to certain of the Company’s intercompany balances denominated in a foreign currency. These derivative instruments are not formally designated as hedges by the Company and the terms of these instruments range at inception from six months to five years. Short-term forward currency contracts are recorded in either other current assets or other current liabilities and long-term forward currency contracts are recorded in either other long-term assets or other long-term liabilities in the condensed consolidated balance sheet. The fair value gains and losses are included in other income, net within the condensed consolidated statements of operations. See Note 7, ''Other Income, net'' for further detail.

The total notional amounts of undesignated forward currency contracts were £45.0 million and £45.0 million as of December 27, 2019 and September 30, 2019, respectively. Cash flows associated with derivative financial instruments are recognized in the operating section of the condensed consolidated statements of cash flows. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

The following table presents the Company's assets and liabilities measured at fair value:

	December 27, 2019						September 30, 2019
(in thousands)	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
Assets
Cash equivalents	$	111,422	$	—	$	—	$	72,132	$	—	$	—
Forward currency contracts	—		297		—		—		3,420		—

The Company's remaining financial instruments consist primarily of cash, accounts receivable and accounts payable whose carrying value approximate their fair value due to their short-term nature.

The estimated fair value of financial instruments not carried at fair value in the condensed consolidated balance sheets were as follows:

	December 27, 2019				September 30, 2019
(in thousands)	Carrying Value		Fair Value		Carrying Value		Fair Value
First Lien Term Loan Facility due December 22, 2023	$	852,120	$	854,677	$	852,120	$	853,543

In determining the approximate fair value of its long-term debt, the Company used the trading values among financial institutions, and these values fall within Level 2 of the fair value hierarchy. The carrying value of the ABL Credit Facility approximates fair value due to it being a market-linked variable rate debt.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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

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

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

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

Leases

The Company elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed us to carry forward prior conclusions about lease identification, classification and initial direct costs for leases entered into prior to adoption of Topic 842. Additionally, for leases with a term of 12 months or less, the Company elected the short-term lease exemption, which allowed us to not recognize right-of-use assets ("ROU") or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future. Leases with an initial term of 12 months or less are classified as short-term leases and are not recorded on the condensed consolidated balance sheets. The lease expense for short-term leases is recognized on a straight-line basis over the lease term.

The Company engages in leasing transactions to meet the needs of the business. The Company leases certain warehouses and distribution centers, office space, forklifts, vehicles and other machinery and equipment. The determination to lease, rather

than purchase, an asset is primarily contingent upon capital requirements, duration of the forecasted business investment, and asset availability.

The Company determines if an arrangement is a lease at inception and all arrangements deemed to be leases are subject to an assessment to determine the classification between finance and operating leases. The Company's significant assumptions and judgments in determining whether a contract is or contains a lease include establishing whether the supplier has the ability to use other assets to fulfill its service or whether the terms of the agreement enable the Company to control the use of a dedicated property, plant and equipment asset during the contract term. In the majority of the Company's contracts where it must identify whether a lease is present, it is readily determinable that the Company controls the use of the assets and obtains substantially all of the economic benefit during the term of the contract. In those contracts where identification is not readily determinable, the Company has determined that the supplier has either the ability to use another asset to provide the service or the terms of the contract give the supplier the rights to operate the asset at its discretion during the term of the contract, in which case the arrangement would not constitute a lease.

Right-of-use assets and lease obligations are recognized based on the present value of the future minimum lease payments over the lease term as of the commencement date. The Company’s lease agreements have terms that include both lease and non-lease components. Lease component fees are included in the present value of future minimum lease payments. Conversely, non-lease components are not subject to capitalization and are expensed as incurred. Per Topic 842, the contractual interest rate is used to calculate the present value of the future minimum lease payments. However, the majority of the Company’s leases do not provide an implicit rate. Therefore, the Company's significant assumption and judgments in determining the discount rate include determining the incremental borrowing rate. The Company’s incremental borrowing rates are based on the term of the lease, the economic environment of the lease and the effect of collateralization. The valuation of the ROU asset also includes lease payments made in advance of the lease commencement date and initial direct costs incurred to secure the lease and is reduced for lease incentives. The lease terms include options to extend or terminate the lease when it is reasonably certain the Company will exercise the options.

Revenue from Contracts with Customers

Dec. 27, 2019

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

3. REVENUE FROM CONTRACTS WITH CUSTOMERS

The Company’s revenue arrangements primarily consist of a single performance obligation to transfer promised goods which is satisfied at a point in time when title, risks and rewards of ownership, and subsequently control have transferred to the customer. This generally occurs when the product is shipped to the customer, with an immaterial amount of transactions in which control transfers upon delivery. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations.

The Company has certain arrangements that require it to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of products to be returned. The Company principally relies on historical experience, specific customer agreements, and anticipated future trends to estimate these amounts at the time of sale and to reduce the transaction price. These arrangements include sales discounts and allowances, volume rebates, and returned goods.

The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. The Company also expenses costs incurred to obtain a contract, primarily sales commissions, as all obligations will be settled in less than one year.

The Company typically receives payment 30 to 60 days from the point it has satisfied the related performance obligation. See Note 18, ''Segment Information'' for revenue disaggregated by geography and product categories.

Leases [Abstract]

Leases

2. LEASES

On October 1, 2019, we adopted ASC Topic 842 using the modified retrospective transition method. Topic 842 requires the recognition of lease assets and liabilities for operating leases, in addition to the finance lease assets and liabilities previously recorded on our condensed consolidated balance sheets. Beginning on October 1, 2019, our condensed consolidated financial statements are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. The modified retrospective transition method required the cumulative effect, if any, of initially applying the guidance to be recognized as an adjustment to our accumulated deficit as of our adoption date. As a result of adopting Topic 842, we recognized additional operating lease assets and liabilities of $45,519 and $46,941 as of October 1, 2019. The discount rate primarily used to calculate that adjustment was the Company's incremental borrowing rate as of the adoption date, October 1, 2019, as a rate implicit in most contracts was not readily determinable. The Company recorded a cumulative effect adjustment of $1,053 to accumulated deficit, net of tax, as a result of the adoption.

The Company elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed us to carry forward prior conclusions about lease identification, classification and initial direct costs for leases entered into prior to adoption of Topic 842. Additionally, for leases with a term of 12 months or less, the Company elected the short-term lease exemption, which allowed us to not recognize right-of-use assets ("ROU") or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future. Leases with an initial term of 12 months or less are classified as short-term leases and are not recorded on the condensed consolidated balance sheets. The lease expense for short-term leases is recognized on a straight-line basis over the lease term.

The Company engages in leasing transactions to meet the needs of the business. The Company leases certain warehouses and distribution centers, office space, forklifts, vehicles and other machinery and equipment. The determination to lease, rather

than purchase, an asset is primarily contingent upon capital requirements, duration of the forecasted business investment, and asset availability.

The Company determines if an arrangement is a lease at inception and all arrangements deemed to be leases are subject to an assessment to determine the classification between finance and operating leases. The Company's significant assumptions and judgments in determining whether a contract is or contains a lease include establishing whether the supplier has the ability to use other assets to fulfill its service or whether the terms of the agreement enable the Company to control the use of a dedicated property, plant and equipment asset during the contract term. In the majority of the Company's contracts where it must identify whether a lease is present, it is readily determinable that the Company controls the use of the assets and obtains substantially all of the economic benefit during the term of the contract. In those contracts where identification is not readily determinable, the Company has determined that the supplier has either the ability to use another asset to provide the service or the terms of the contract give the supplier the rights to operate the asset at its discretion during the term of the contract, in which case the arrangement would not constitute a lease.

Right-of-use assets and lease obligations are recognized based on the present value of the future minimum lease payments over the lease term as of the commencement date. The Company’s lease agreements have terms that include both lease and non-lease components. Lease component fees are included in the present value of future minimum lease payments. Conversely, non-lease components are not subject to capitalization and are expensed as incurred. Per Topic 842, the contractual interest rate is used to calculate the present value of the future minimum lease payments. However, the majority of the Company’s leases do not provide an implicit rate. Therefore, the Company's significant assumption and judgments in determining the discount rate include determining the incremental borrowing rate. The Company’s incremental borrowing rates are based on the term of the lease, the economic environment of the lease and the effect of collateralization. The valuation of the ROU asset also includes lease payments made in advance of the lease commencement date and initial direct costs incurred to secure the lease and is reduced for lease incentives. The lease terms include options to extend or terminate the lease when it is reasonably certain the Company will exercise the options.

The Company has certain leasing agreements, related to leased vehicles available to our sales personnel, that contain guaranteed residual value terms, which are not expected to be triggered. The Company’s leasing portfolio does not contain any material restrictive covenants.

Goodwill balances as of October 1, 2019 and December 27, 2019 include $3,924 and $43,000 of accumulated impairment losses within the Electrical Raceway and MP&S segments, respectively.

The Company assesses the recoverability of goodwill and indefinite-lived trade names on an annual basis in accordance with ASC 350, "Intangibles - Goodwill and Other." The measurement date is the first day of the fourth fiscal quarter, or more frequently, if events or circumstances indicate that it is more likely than not that the fair value of a reporting unit or the respective indefinite-lived trade name is less than the carrying value.

The following table provides the gross carrying value, accumulated amortization and net carrying value for each major class of intangible assets:

Guarantees

17. GUARANTEES

The Company had outstanding letters of credit totaling $9,501 supporting workers' compensation and general liability insurance policies as of December 27, 2019. The Company also had surety bonds primarily related to performance guarantees on supply agreements and construction contracts, and payment of duties and taxes totaling $18,498 as of December 27, 2019.

In disposing of assets or businesses, the Company often provides representations, warranties and indemnities to cover various risks including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities, and unidentified tax liabilities and legal fees related to periods prior to disposition. The Company does not have the ability to estimate the potential liability from such indemnities because they relate to unknown conditions. However, the Company has no reason to believe that these uncertainties would have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.

In the normal course of business, the Company is liable for product performance and contract completion. In the opinion of management, such obligations will not have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

9. EARNINGS PER SHARE

The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating securities as if all of the net earnings for the period had been distributed. The Company's participating securities consist of share-based payment awards that contain a non-forfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common stockholders.

Basic earnings per common share excludes dilution and is calculated by dividing the net earnings allocable to common stock by the weighted-average number of common stock outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocated to common stock by the weighted-average number of shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.

The following table sets forth the computation of basic and diluted earnings per share:

	Three months ended
(in thousands, except per share data)	December 27, 2019		December 28, 2018
Numerator:
Net income	$	34,790	$	26,949
Less: Undistributed earnings allocated to participating securities	857		653
Net income available to common shareholders	$	33,933	$	26,296
Denominator:
Basic weighted average common shares outstanding	47,126		46,995
Effect of dilutive securities: Non-participating employee stock options (1)	873		1,288
Diluted weighted average common shares outstanding	47,999		48,283
Basic earnings per share	$	0.72	$	0.56
Diluted earnings per share	$	0.71	$	0.54
(1) Stock options to purchase approximately 0.1 million and 0.6 million shares of common stock were outstanding during the three months ended December 27, 2019 and December 28, 2018, respectively, but were not included in the calculation of diluted earnings per share as the impact of these options would have been anti-dilutive.
