BMC STOCK HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. Organization

These unaudited financial statements represent the financial statements of BMC Stock Holdings, Inc., and its subsidiaries. All references to ~~“BMC,” “we,” “us,” “our”~~“BMC” or the “Company” mean BMC Stock Holdings, Inc. and its subsidiaries.

The Company distributes lumber and building materials to new construction and repair and remodeling contractors. Additionally, ~~we provide~~the Company provides solution-based services to ~~our~~its customers, including component design, product specification and installation services.

2. Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The condensed consolidated balance sheet as of December 31, ~~2016~~2018 was derived from audited financial statements, but does not include all necessary disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The unaudited condensed consolidated financial statements include all accounts of the Company and, ~~its subsidiaries and,~~ in the opinion of management, include all recurring adjustments and normal accruals necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the dates and periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2016~~2018 (“~~2016~~2018 Annual Report on Form 10-K”). Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. All material intercompany accounts and transactions have been eliminated in consolidation.

~~Reclassifications~~

~~Certain prior year amounts have been reclassified to conform to the current year presentation.~~

Comprehensive income

Comprehensive income is equal to the net income for all periods presented.

Cash equivalents

Cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and have a maturity of three months or less from the time of purchase. As of September 30, 2019 and December 31, 2018, the Company had cash equivalents of $156.9 million and $146.1 million, respectively. Cash equivalents are valued at amortized cost, which approximates fair value due to the short-term maturity of these instruments, and were classified as Level 1 or Level 2 measurements in accordance with Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“ASC 820”).

Share repurchase program

In November 2018, the Company’s board of directors authorized a $75.0 million share repurchase program, which was to expire on November 20, 2019. During October 2019, the Company’s board of directors authorized extending this share repurchase program for one year, such that it will expire on November 20, 2020. During the nine months ended September 30, 2019, utilizing cash from operations, the Company repurchased 1.0 million shares at a weighted average price of $17.11 per share for a total cost of $16.4 million. These repurchased shares are available for future issuance and are reflected as treasury stock, at cost, on the condensed consolidated balance sheets. As of September 30, 2019, the Company had approximately $55.7 million of capacity remaining under the current share repurchase authorization.

Statement of cash flows

Proceeds from revolving line of credit and repayments of proceeds from revolving line of credit as presented on the condensed consolidated statements of cash flows includes all cash activities and transactions between the Company and its associated lenders in relation to the revolving line of credit, excluding interest and fees, and is specifically inclusive of operating cash receipts that are automatically applied to the revolving line of credit pursuant to a cash sweep agreement. See Note 6 for further details on the Company’s revolving line of credit.

Prior Period Misstatement

During the three months ended June 30, 2019, the Company identified that a former credit manager within one of its local operations violated the Company’s credit policy by intentionally misapplying certain customer payments, both within a single customer balance as well as across multiple customer balances, and created inappropriate debit memos, all with the intent to manipulate the aging of certain unpaid customer invoices. These inappropriate activities resulted in an understatement of the Company’s provision for doubtful accounts in previously issued annual and interim financial statements (the “Prior Period Misstatement”). The Company

has corrected for such Prior Period Misstatement by recording, during the three months ended June 30, 2019 (which is included in the nine months ended September 30, 2019), an out of period bad debt expense of approximately $4.3 million in selling, general and administrative expenses and a corresponding decrease to accounts receivable, net of allowances. The Company has concluded that the financial impact of the Prior Period Misstatement is not material to any of its previously issued financial statements and that the correction of such Prior Period Misstatement is not material to either the nine months ended September 30, 2019 or to the expected financial results for the year ending December 31, 2019.

Recently adopted accounting pronouncements

In ~~July 2015,~~February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 requires that inventory within the scope of the guidance be measured at the lower of cost and net realizable value. Prior to the issuance of the standard, inventory was measured at the lower of cost or market, where market was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin. Inventory measured using last-in, first-out (LIFO) and the retail inventory method are not impacted by the new guidance. Prospective application is required and early adoption is permitted. ASU 2015-11 became effective for the Company’s annual and interim periods beginning on January 1, 2017. The adoption of the guidance did not have a material impact on our financial statements.

~~Recently issued accounting pronouncements not yet adopted~~

~~In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”),~~2016-02, Leases, and issued subsequent amendments to the initial guidance ~~within Accounting Standards Update 2016-08, Revenue from Contracts with Customers, Principal versus Agent Considerations~~to provide additional clarification on specific topics (“ASU 2016-08”) issued in March 2016, Accounting Standards Update 2016-10, Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing (“ASU 2016-10”) issued in April 2016, Accounting Standards Update 2016-12, Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”) issued in May 2016 and Accounting Standards Update 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”) issued in December 2016 (ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 collectively2016-02” or “Topic ~~606”~~842”). Topic 606 provides a comprehensive revenue recognition model requiring companies to recognize revenue for the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, and therefore, the standard is effective for the Company’s annual and interim periods beginning on January 1, 2018. The guidance permits the use of either a full retrospective or modified retrospective transition method. We expect to adopt the standard on January 1, 2018 using the modified retrospective transition method, which recognizes the cumulative effect of initially applying the standard in retained earnings on the date of adoption, with the option to utilize certain practical expedients as defined in Topic 606. We do not expect the adoption of the standard to have a material impact on the timing of revenue recognition nor the amount of revenue recognized

from our building products contracts. Revenue for our building products contracts will continue to be recognized at a point in time, when control of the promised goods is transferred to our customers, with the exception of certain product offerings which are customized to customer specifications and meet the criteria to be recognized over time, which is consistent with the Company’s current accounting. We are continuing to evaluate the impact of the standard on our contracts with a service element but based on our current assessment, we expect that revenue for our construction services contracts will generally continue to be recognized over time as the Company satisfies the performance obligations in the contracts. We also continue to evaluate the disclosure requirements of the standard, which are expected to be significant and incremental to the current disclosures.

~~In February 2016, the FASB issued Accounting Standards Update~~ 2016-02 ~~Leases (“ASU 2016-02”). The new standard~~ establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the ~~income statement.~~statement of operations. The Company adopted ASU 2016-02 on January 1, 2019 by recording ROU assets for its operating leases totaling approximately $110 million and corresponding lease liabilities totaling approximately $115 million. The impact of adopting ASU 2016-02 was not material to the Company’s results of operations or cash flows for the three and nine months ended September 30, 2019. See Note 5 for further details.

Recently issued accounting pronouncements not yet adopted

In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. ASU 2016-13 is effective for the Company’s annual and interim periods beginning on January 1, 2019. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We are in the process of evaluating the impact of the standard on our financial statements. As a lessee, certain of our various leases under existing guidance are classified as operating leases that are not recorded on the balance sheet but are recorded in the statement of operations as expense is incurred. Upon adoption of the standard, we will be required to record substantially all leases on the balance sheet as a ROU asset and a lease liability. The timing of expense recognition and classification in the statement of operations could change based on the classification of leases as either operating or financing.

In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”).

In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires computation of the implied fair value of a reporting ~~unit's~~unit’s goodwill. The amount of a goodwill impairment will now be the amount by which a reporting ~~unit's~~unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.

3. Acquisitions

For all acquisitions, the Company allocates the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives.

~~Acquisition of Code Plus Components, LLC~~

On March 27, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Code Plus Components, LLC (“Code Plus”), a manufacturer of structural components located in Martinsburg, West Virginia, for a purchase price of $7.1 million. This acquisition allowed the Company to add truss manufacturing capability to its value-added offerings in the Washington, DC metro area. The purchase price includes an initial holdback of $0.4 million due to the sellers one year from the closing date. The holdback amount may be reduced under certain circumstances. Additionally, the acquisition includes an earnout provision that would require the Company to pay the sellers up to an additional $0.8 million upon the acquired operations achieving certain performance targets from the acquisition date through December 31, 2018. The Company ~~funded the transaction through borrowings on the Company’s revolving line of credit.~~

~~The acquisition was accounted~~accounts for all acquisitions using the acquisition method of accounting under ASC 805, Business Combinations, whereby the results of operations of ~~Code Plus~~the acquired company are included in the Company’s consolidated financial statements beginning on the acquisition date.

2019 Acquisitions

The Company completed the following acquisitions during the nine months ended September 30, 2019:


•	On January 14, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Barefoot and Company (“Barefoot”), a supplier of windows, exterior doors, hardware, specialty products and installation services in the Charlotte, North Carolina metropolitan area.


•	On February 8, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Locust Lumber, a supplier of lumber products and building materials primarily to custom homebuilders and professional remodeling contractors in the Charlotte, North Carolina metropolitan area.


•	On August 1, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Kingston Lumber, a supplier of lumber products, trusses and other building materials primarily to custom homebuilders and professional remodeling contractors in the Seattle, Washington metropolitan area.


•	On September 3, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Heritage One Door & Carpentry (“Heritage One”), a supplier of pre-hung doors, millwork, hardware and finish carpentry services in the Sacramento, California metropolitan area.


•	On September 16, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Colorado Fasteners, a supplier of fasteners, tools and other related products in the Denver, Colorado metropolitan area.

The Barefoot, Locust Lumber, Kingston Lumber, Heritage One and Colorado Fasteners acquisitions (the “2019 Acquisitions”) enhance the Company’s value-added offerings and footprint in the respective metropolitan areas.

The preliminary purchase price, in aggregate, for the 2019 Acquisitions was $90.9 million. The preliminary purchase price includes holdbacks which, after certain post-closing adjustments, require the Company to pay $5.5 million, in aggregate, to the sellers of Barefoot, Kingston Lumber, Heritage One and Colorado Fasteners one year from the respective closing dates. The holdback amounts may be further reduced under certain circumstances. The Company funded the 2019 Acquisitions through available cash.

The preliminary purchase price allocation for the 2019 Acquisitions, in aggregate, resulted in the initial recognition of goodwill of ~~$3.4~~$20.4 million, a customer relationship intangible ~~asset~~assets of ~~$2.3~~$33.1 million, ~~and a~~ non-compete agreement intangible ~~asset~~assets of $0.5 million, accounts receivable of $22.1 million, inventory of $14.7 million and property and equipment of $5.6 million, as well as other operating assets and liabilities. The customer relationship ~~intangible asset~~ and non-compete agreement intangible ~~asset~~assets have a weighted average useful ~~lives~~life of 129 years and 54 years, respectively. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill ~~recognized~~ is expected to be deductible for tax purposes.

The purchase price allocations for the 2019 Acquisitions are preliminary and based upon all information available to the Company at the present time, and are subject to change. The Company is in the process of finalizing its valuation of the acquired intangible assets, property and equipment and inventory, and therefore, the initial purchase accounting for the 2019 Acquisitions is not complete. As the Company receives additional information during the measurement period, the fair values assigned to the assets and liabilities may be adjusted.

For the year ended December 31, ~~2016, Code Plus~~2018, the 2019 Acquisitions generated net sales, in aggregate, of approximately ~~$14.2~~$199 million. The Company incurred transaction costs of $0$0.2 million and ~~$0.1~~$0.5 million for the three and nine months ended September 30, ~~2017,~~2019, respectively, ~~which are~~related to the 2019 Acquisitions.

Net sales and estimated pre-tax earnings for the 2019 Acquisitions included in the unaudited condensed consolidated statements of operations during the nine months ended September 30, 2019 were $84.6 million and $7.1 million, respectively. The impact of the 2019 Acquisitions was not considered significant for the reporting of pro forma financial information.

2018 Acquisition ~~of Texas Plywood & Lumber Company, Inc.~~

On ~~April 3, 2017,~~March 1, 2018, the Company acquired substantially all of the assets and assumed certain liabilities of ~~Texas Plywood & Lumber Company, Inc.~~W.E. Shone Co. (“~~TexPly”~~Shone Lumber”), a supplier of ~~production millwork and doors~~building materials in the ~~Dallas-Fort Worth area,~~state of Delaware, for a ~~preliminary~~ purchase price of $32.0 million, of which $2.5 million was deposited in an escrow account to fund post-closing adjustments and other indemnification obligations for a period of one year from the closing date of the acquisition.$22.4 million. This acquisition enhances the Company’s value-added offerings and footprint in the ~~Dallas-Fort Worth market.~~Mid-Atlantic region. The purchase price included a holdback that, after certain post-closing adjustments, required the Company to pay $1.4 million to the sellers during the nine months ended September 30, 2019. The Company funded the transaction through available cash and borrowings on the Company’s revolving line of credit.

The acquisition was accounted for using the acquisition method of accounting under ASC 805, Business Combinations, whereby the results of operations of TexPly are included in the Company’s consolidated financial statements beginning on the acquisition date. The preliminary purchase price allocation resulted in the ~~initial~~ recognition of goodwill of ~~$3.8~~$2.5 million, a customer relationship intangible asset of ~~$13.4~~$7.0 million, accounts receivable of ~~$5.2~~$6.4 million, inventory of ~~$4.0~~$8.8 million, property and equipment of $2.9 million and ~~real property~~total current liabilities of ~~$5.4~~$5.3 million, as well as other operating ~~assets and liabilities.~~assets. The customer relationship intangible asset has a useful life of 139 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes.

For the year ended December 31, 2016, TexPly generated net sales of approximately $55.2 million. The Company incurred transaction costs of $0 and $0.2 million for the three and nine months ended September 30, 2017, respectively, which are included in selling, general and administrative expenses in the unaudited condensed consolidated statements of operations.

The purchase price allocations of Code Plus and TexPly are preliminary and based upon all information available to the Company at the present time, and are subject to change. The Company is in the process of finalizing its valuation of the acquired intangible assets, property and equipment and inventory and therefore, the initial purchase accounting is not complete. As we receive additional information during the measurement period, the fair values assigned to the assets and liabilities may be adjusted.

5. ~~Impairment~~Leases

Adoption of ~~BMHC ERP System~~Topic 842

During 2013, Building Materials Holding Corporation (“BMHC” or “Legacy BMHC”) selected a new third-party software vendor for its planned Enterprise Resource Planning (“New ERP”) system and began incurring costs related to design, development and implementation of the New ERP. BMHC also began paying an annual licensing fee. During March 2016,On January 1, 2019, the Company ~~decided~~adopted Topic 842 by applying the guidance at adoption date. As a result, the comparative information as of December 31, 2018 and for the three and nine months ended September 30, 2018 has not been adjusted and continues to ~~integrate all operations~~be reported under ASC 840, Leases (“ASC 840”). The Company elected the package of practical expedients permitted under the Enterprise Resource Planning system utilized by Stock Building Supply Holdings, Inc. (“SBS” and the “Legacy SBS ERP system”) and to discontinue use of the New ERP. In connection with this decision,transition guidance within Topic 842, which allowed the Company ~~recorded asset impairment charges~~to carry forward its identification of ~~approximately $11.9 million in~~contracts that are or contain leases, its historical lease classification and its accounting for initial direct costs for existing leases. The impact of adopting Topic 842 was not material to the Company’s results of operations or cash flows for the three and nine months ended September 30, 2019.

Beginning January 1, 2019, the Company recognized ROU assets and lease liabilities for the Company’s operating leases on its unaudited condensed consolidated ~~statement~~balance sheets. ROU assets for the Company’s operating leases are presented within operating lease right-of-use assets on the Company’s condensed consolidated balance sheets, while the lease liabilities for the Company’s operating leases are presented within operating lease liabilities, with a current and long-term portion. Upon adoption of ~~operations~~Topic 842, the balances at the adoption date of prepaid and accrued rent, lease incentives and unamortized assets and liabilities related to favorable and unfavorable leases were reclassified and are now presented within operating lease right-of-use assets on the Company’s condensed consolidated balance sheets. Refer to further discussion of the Company’s ROU assets and lease liabilities below. The Company’s accounting for its historical capital leases, which are now presented as finance leases under Topic 842, remained substantially unchanged.

Lease Arrangements

The Company has operating and finance leases primarily for its facilities, office space, land, fleet vehicles and equipment. Many of the Company’s leases are noncancellable and typically have an initial lease term of five to ten years, and most provide options at the Company’s election to renew for specified periods of time. The Company’s leases generally provide for fixed annual rentals. Certain of the Company’s leases include provisions for escalating rent, as an example, based on changes in the consumer price index. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement. Most of the Company’s leases require it to pay taxes, insurance and maintenance expenses associated with the properties. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The Company determines if an arrangement contains a lease at inception. The Company has lease agreements with lease and non-lease components, which for all such leases are generally accounted for separately. The Company has elected the short-term lease exception under Topic 842 for all leases and as such, leases with an initial term of 12 months or less are not recorded on the

unaudited condensed consolidated balance sheets. The Company recognizes lease expense for short-term leases on a straight-line basis over the lease term.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As the Company’s leases generally do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and any initial direct costs incurred. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Senior Secured Notes

On September 15, 2016, the Company issued $350.0 million of senior secured notes due 2024 (the “Senior Notes”) under an unregistered private placement not subject to the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The Senior Notes were issued by BMC East, LLC, a 100% owned subsidiary of the Company, and are guaranteed by the Company and the other subsidiaries that guarantee ~~our~~the Credit Agreement (as defined below). Each of the subsidiary guarantors is 100% owned, directly or indirectly, by the Company, and all guarantees are full and unconditional and joint and several. The interest rate is fixed at 5.5% and is payable semiannually on April 1 and October 1.

The net cash proceeds from the Senior Notes were used to redeem in full $250.0 million of 9.0% senior secured notes that were issued by BMHC in September 2013 and that were scheduled to mature in September 2018 (the “Extinguished Senior Notes”). In connection with the redemption of the Extinguished Senior Notes, the Company incurred a loss on debt extinguishment of $12.5 million for the nine months ended September 30, 2016, consisting of a call premium of $8.4 million, and the write-off of unamortized debt issuance costs and original issue discount of $4.1 million.

As of September 30, ~~2017,~~2019, the estimated market value of the Senior Notes was ~~$16.6~~approximately $14.4 million higher than the carrying amount. The fair value is based on institutional trading activity and was classified as a Level 2 measurement in accordance with ASC 820.

Revolving Credit Agreement

On December 1, 2015 we, the Company entered into a senior secured credit agreement with Wells Fargo Capital Finance, as administrative agent, and certain other lenders ~~(the “Credit~~(as amended by the first and second amendments, the “Existing Credit Agreement”), which includes a revolving line of credit (the “Revolver”). ~~The~~On May 31, 2019, the Company entered into the third amendment to the Existing Credit Agreement as(the “Third Amendment”), which amended ~~has an~~and restated the Existing Credit Agreement (the “Credit Agreement”) and increased the aggregate commitment offrom $375.0 million to $425.0 million. WeThe Company had 0 outstanding borrowings under the Revolver ~~of $51.8 million with~~and net availability of ~~$256.4~~$367.8 million as of September 30, ~~2017.~~2019. The ~~weighted average interest rate on outstanding LIBOR Rate borrowings of $40.0 million was 2.74% and the interest rate on Base Rate borrowings of $11.8 million was 4.75% as of September 30, 2017. We~~Company had ~~$66.8~~$56.1 million in letters of credit outstanding under the Credit Agreement as of September 30, ~~2017.~~2019.

The ~~carrying value~~Credit Agreement matures at the earlier of (i) May 31, 2024 or (ii) if the Senior Notes are refinanced or repaid, the date that is 91 days prior to the new maturity date of the ~~Revolver at September 30, 2017 approximates fair value as~~replacement notes or other indebtedness that replaced or refinanced the ~~rates are comparable to those at which we could currently borrow under similar terms, are variable and incorporate a measure of our credit risk. As such, the fair value~~Senior Notes. The effective maturity date of the Revolver was extended from December 1, 2020, the effective maturity date of the Existing Credit Agreement, to May 31, 2024. After considering the increase to the remaining term and the increase in the aggregate commitment resulting from the Third Amendment, the overall borrowing capacity of the Revolver increased. Accordingly, all existing unamortized debt issuance costs and new debt issuance costs related to the Third Amendment are being amortized through May 31, 2024.

Company’s contracts generally have an original expected length of one year or less.

8. Income Taxes

The Company evaluates its deferred tax assets quarterly to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company had a valuation allowance of $0.1 million against its deferred tax assets related to certain state tax jurisdictions as of September 30, ~~2017~~2019 and December 31, ~~2016.~~2018. To the extent the Company generates future tax net operating losses, the Company may be required to increase the valuation allowance on deferred tax assets, which may unfavorably impact the effective tax rate.

The Company has no material uncertain tax positions as of September 30, ~~2017~~2019 and December 31, ~~2016.~~2018.

During the three and nine months ended September 30, 2019, the Company recorded an out of period expense of $1.6 million and $1.5 million, respectively, in Income tax expense and a corresponding increase to Income taxes payable to correct for a misstatement related to its calculation of excess windfall tax benefits on stock option exercises in certain prior periods (the “Income Tax Adjustment”). The Company has concluded that the financial impact of the Income Tax Adjustment is not material to any of its previously issued financial statements and that the correction of such Income Tax Adjustment is not material to either the three or nine months ended September 30, 2019 or to the expected financial results for the year ending December 31, 2019.

For the three and nine months ended September 30, ~~2017,~~2019, the Company’s effective tax rate was ~~34.1%~~28.2% and ~~33.3%~~24.9%, respectively, which varied from the federal statutory rate of ~~35%~~21% primarily due to ~~excess~~state income taxes and the Income Tax Adjustment. Excluding the Income Tax Adjustment, the Company’s effective tax ~~windfall benefits from stock compensation~~rate was 24.7% and ~~a permanent domestic manufacturing deduction under Internal Revenue Code Section 199 (the “Manufacturing Deduction”).~~23.6% for the three and nine months ended September 30, 2019, respectively. For the three and nine months ended September 30, ~~2016,~~2018, the Company’s effective tax rate was ~~35.0%~~23.4% and ~~32.7%~~23.3%, respectively, which varied from the federal statutory rate of ~~35%~~21% primarily due to ~~the excess tax windfall benefit from stock compensation and the Manufacturing Deduction.~~state income taxes.

8.9. Commitments and Contingencies

From time to time, various claims, legal proceedings and litigation are asserted or commenced against the Company principally arising from alleged product liability, warranty, casualty, construction defect, contract, tort, employment and other disputes. In

determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. It is not certain that the Company will prevail in these matters. However, the Company does not currently believe that the ultimate outcome of any pending matters will have a material adverse effect on its consolidated financial position, results of operations or cash flows. ~~The~~As of December 31, 2018, the Company ~~recorded~~had accrued $3.0 million ~~of expense within selling, general and administrative expenses~~ in ~~its unaudited condensed consolidated statements of operations for~~relation to pending litigation that was recorded during the ~~three and~~year ended December 31, 2017.

11. Segments

ASC 280, Segment Reporting, 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 (“CODM”) in deciding how to allocate resources and in assessing performance.

~~Beginning January 1, 2017, the~~The Company’s operating segments consist of the Mid-Atlantic, Southeast, Texas, Intermountain and Western divisions after the Company realigned certain of its markets, which resulted in the consolidation of the Company’s historical Mountain West division into the Intermountain division.

Based on ~~this,~~the CODM’s review, as well as the similar economic characteristics, nature of products, distribution methods and customers of the divisions, ~~both before and after the realignment,~~ the Company has aggregated its operating segments into ~~one~~1 reportable segment, “Geographic divisions.”

In addition to ~~our~~the Company’s reportable segment, the Company’s consolidated results include “Other reconciling items.” Other reconciling items ~~is comprised of our~~comprises the Company’s corporate activities and other income and expenses not allocated to the operating segments.

The following tables present Net Sales, Adjusted EBITDA and certain other measures for the reportable segment and total Company operations for the three and nine months ended September 30, ~~2017~~2019 and ~~2016.~~2018. Adjusted EBITDA is used as a performance metric by the CODM in determining how to allocate resources and assess performance. For the nine months ended September 30, 2019, Adjusted EBITDA for the Geographic divisions reportable segment includes the out of period correction of the Prior Period Misstatement of $4.3 million.

~~11.~~12. Earnings Per Share

Basic net income per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options, restricted stock and restricted stock unit awards are considered to be potential common shares. Performance-based restricted stock units are not included in the calculation of diluted EPS until they are contingently issuable.

The basic and diluted EPS calculations for the three and nine months ended September 30, ~~2017~~2019 and ~~2016~~2018 are presented below:

ITEM 2 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our historical consolidated financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q and with our audited financial statements included in our ~~2016~~2018 Annual Report on Form 10-K. All references to “BMC,” “we,” “us,” “our” or the “Company” mean BMC Stock Holdings, Inc. and its subsidiaries.

Cautionary Statement with Respect to Forward-Looking Statements

Some of the statements contained in this Quarterly Report on Form 10-Q constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts or present facts or conditions. In many cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or the negative of these terms or other comparable terminology.

The forward-looking statements reflect our views about future events and are subject to risks, uncertainties, assumptions and changes in circumstances that may cause events or our actual activities or results to differ significantly from those expressed in any forward-looking statement. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future events, results, actions, levels of activity, performance or achievements.

Overview

We are one of the leading providers of diversified building products and services in the U.S. residential construction market. Our objective is to provide best-in-class customer service and value-added products to our customers, which are primarily single- and multi-family home builders and professional remodelers. Our product offerings include lumber and lumber sheet goods and an array of value-added products including millwork, doors, windows and structural components such as engineered wood products, floor and roof trusses and wall panels. ~~Our~~We believe our whole-house framing solution, Ready-Frame®, which is one of our fastest growing product offerings, saves builders both time and money and improves job site safety. We also offer our customers important services such as design, product specification, installation and installation management.

The 18 states in which we operate accounted for approximately ~~64%~~66% of ~~2016~~2018 U.S. single-family housing permits according to the U.S. Census Bureau. In these 18 states, we operate in 4345 metropolitan areas.

Our net sales for the three months ended September 30, ~~2017 increased 7.3%~~2019 decreased 2.6% compared to the prior year period. Our gross ~~margin~~profit as a percentage of sales (“gross margin”) was ~~23.8%~~26.4% for the three months ended September 30, ~~2017~~2019 compared to ~~24.7%~~24.4% for the prior year period. We recorded income from operations of ~~$33.3~~$49.0 million during the three months ended September 30, ~~2017~~2019 compared to ~~$33.7~~$49.8 million during the three months ended September 30, ~~2016.~~2018. See further discussion in “-Operating Results” below.

Factors Affecting Our Operating Results

Our operating results and financial performance are influenced by a variety of factors, including, among others, acquisitions, conditions in the housing market and economic conditions generally, changes in the cost of the products we sell (particularly commodity products), pricing policies of our competitors, production schedules of our customers and seasonality. Some of the more important factors are ~~briefly~~ discussed in our 2018 Annual Report on Form 10-K, as supplemented by the additional discussion below.

Acquisitions

~~On March 27, 2017, the~~The Company completed the ~~acquisition~~following acquisitions during the nine months ended September 30, 2019:

On January 14, 2019, the Company acquired substantially all of ~~Code Plus,~~the assets and assumed certain liabilities of Barefoot, a ~~truss manufacturer located~~supplier of windows, exterior doors, hardware, specialty products and installation services in ~~Martinsburg, West Virginia serving~~ the Charlotte, North Carolina metropolitan area.

On September 3, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Heritage One, a supplier of pre-hung doors, millwork, hardware and finish carpentry services in the Sacramento, California metropolitan area.

On September 16, 2019, the Company acquired substantially all of the assets and assumed certain liabilities of Colorado Fasteners, a supplier of fasteners, tools and other related products in the Denver, Colorado metropolitan area.

The preliminary purchase price, in aggregate, for the 2019 Acquisitions was $90.9 million.

On March 1, 2018, the Company acquired substantially all of the assets and assumed certain liabilities of Shone Lumber, a supplier of building materials in the state of Delaware, for a purchase price of ~~$7.1 million. On April 3, 2017, the Company completed the acquisition of TexPly, a supplier of production millwork and doors in the Dallas-Fort Worth area, for a preliminary purchase price of $32.0~~$22.4 million.

~~Approximately $18.5~~

The 2019 Acquisitions increased sales approximately $38.7 million ~~and $38.0 million of the sales increase~~ for the three ~~and nine~~ months ended September 30, ~~2017, respectively,~~2019, compared to the prior year period, ~~is a result of~~while the ~~Code Plus~~2019 Acquisitions and ~~TexPly acquisitions.~~Shone Lumber acquisition increased sales approximately $93.1 million for the nine months ended September 30, 2019, compared to the prior year period.

Conditions in the housing and construction market

The building products supply and services industry is highly dependent on new single-family home and multi-family construction and repair and remodeling activity, which in turn are dependent upon a number of factors, including, among other things, ~~interest rates,~~overall economic conditions. Unfavorable economic changes, both nationally and locally in our markets, could adversely affect consumer ~~confidence, employment rates, foreclosure rates, housing inventory levels, housing~~spending, result in decreased demand ~~the availability of land, the availability of construction financing~~for homes and ~~the health of the economy and mortgage markets.~~adversely affect our business. According to the U.S. Census Bureau, single-family housing starts in the South and West regions of the United States, which are our primary operating regions, increased approximately ~~11.2%~~5.1% for the three months ended September 30, ~~2017 as~~2019 compared to the same period in the prior year.

~~Overall economic conditions in the markets where we operate~~

Economic changes both nationally and locally in our markets impact our financial performance. Unfavorable changes in demographics, credit markets, consumer confidence, health care costs, housing affordability, housing inventory levels, a weakening of the national economy or of any regional or local economy in which we operate and other factors beyond our control could adversely affect consumer spending, result in decreased demand for homes and adversely affect our business. We believe continued

employment growth, prospective home buyers’ access to financing and improved consumer confidence will be necessary to increase household formation rates. We believe improved household formation rates in turn will increase demand for housing and stimulate new construction.

Commodity nature of our products

Many of the building products we distribute, including lumber, oriented strand board (“OSB”), plywood and particleboard, are commodities that are widely available from other manufacturers or distributors with prices and volumes determined frequently based on participants’ perceptions of short-term supply and demand factors.

The following table reflects changes in the average composite framing lumber prices (per thousand board feet) and average composite structural panel prices (per thousand square feet). These prices represent transactions between manufacturers and their customers as reported by Random Lengths and may differ in magnitude or timing from the actual selling prices or cost of goods reported in our operating results. The average composite structural panel prices are based on index prices for OSB and plywood.


	Three Months Ended September 30,				Nine Months Ended September 30,				Three Months Ended September 30,				Nine Months Ended September 30,
	2017 versus 2016		2017 average price		2017 versus 2016		2017 average price		2019 versus 2018		2019 average price		2019 versus 2018		2019 average price
Framing lumber prices	16.8	%	$	418	18.1	%	$	405	(23.6	)%	$	357	(29.0	)%	$	353
Structural panel prices	20.3	%	$	468	14.3	%	$	423	(30.2	)%	$	337	(31.1	)%	$	353

Periods of increasing prices provide the opportunity for higher sales and increased gross profit, while periods of declining prices may result in declines in sales and profitability. In particular, low market prices for wood products over a sustained period can adversely affect our financial condition, operating results and cash flows, as can excessive spikes in market prices. The impact of commodity price changes on our operating results is partially dependent on pricing commitments with our customers. For further discussion of the impact of commodity prices on historical periods, see “-Operating Results” below.

~~Consolidation of large homebuilders~~

~~Our ability to control expenses~~

We pay close attention to managing our working capital and operating expenses. We employ a LEAN process operating philosophy, which encourages continuous improvement in our core processes to minimize waste, improve customer service, increase expense productivity, improve working capital and maximize profitability and cash flow. We regularly analyze our workforce productivity to achieve the optimum, cost-efficient labor mix for our facilities. Further, we pay careful attention to our logistics function and have implemented GPS-enabled telematics technology across our delivery fleet to improve customer service and improve productivity of our shipping and handling costs.

Mix of products sold

We typically realize greater gross margins on more highly engineered and customized products, or ancillary products that are often purchased based on convenience and are therefore less price sensitive to our customers. For example, sales of lumber &and lumber sheet goods tend to generate lower gross margins due to their commodity nature and the relatively low switching costs of sourcing those products from different suppliers. Structural components and millwork, doors &and windows often generate higher gross margins relative to other products. ~~Homebuilders often use structural components in order to realize increased efficiency and improved quality. We believe shortening cycle time from start to completion is a key goal~~For further discussion of ~~homebuilders during~~the impact of mix of products sold on historical periods, of strong consumer demand or limited availability of framing labor. As the residential new construction market continues to strengthen, we expect the use of structural components by homebuilders to increase.

see “-Operating Results” below.

Changes in customer sales mix

Our operating results may vary according to the amount and type of products we sell to each of our primary customer types: ~~new~~ single-family homebuilders, ~~professional~~ remodeling contractors and multi-family, ~~builders~~commercial and ~~light commercial builders.~~other contractors. We tend to realize higher gross margins on sales to remodeling contractors due to the smaller product volumes purchased by those customers, as well as the more customized nature of the projects those customers generally undertake. Gross margins on sales to ~~single-family, multi-family and light commercial customers~~our other primary customer types can vary based on a variety of factors, including the purchase volumes of the individual customer, the mix of products sold to that customer, the size and selling price of the project being constructed and the number of upgrades added to the project before or during its construction. factors.

Our first and fourth quarters have historically been, and are generally expected to continue to be, adversely affected by weather patterns in some of our markets, causing reduced construction activity. As a result, sales are usually lower in the first and fourth quarters than in the second and third quarters.

The following table sets forth our operating results in dollars and as a percentage of net sales for the periods indicated:

During ~~2017~~2019 and ~~2016,~~2018, our capital resources have primarily consisted of cash and cash equivalents generated through operating cash flows ~~proceeds from the September 2016 issuance of the Senior Notes~~ and borrowings under our Revolver.

Capital expenditures

Capital expenditures vary depending on prevailing business factors, including current and anticipated market conditions. We expect our ~~2017~~2019 capital expenditures, ~~including the incurrence of capital lease obligations and~~ net of proceeds from the sale of property, equipment and real estate, to be approximately ~~$65.0~~$80.0 million to ~~$75.0~~$90.0 million primarily related to vehicles and equipment, including lease buyouts, to replace aged assets and support increased sales volume, and facility and technology investments to support our operations. For the nine months ended September 30, ~~2017,~~2019, capital expenditures, ~~including the incurrence of capital lease obligations and~~ net of proceeds from the sale of property, equipment and real estate, were ~~$50.2~~$63.1 million.

Senior secured notes

On September 15, 2016, the Company issued $350.0 million of Senior ~~Notes under an unregistered private placement not subject to the registration requirements of the Securities Act.~~Notes. The Senior Notes mature on October 1, 2024 and are secured by a first priority lien on certain assets of the Company and a second priority lien on the collateral that secures the Credit Agreement, which collectively approximates substantially all assets of the Company. The interest rate is fixed at 5.5% and is payable semiannually on April 1 and October 1. The ~~Indenture~~indenture governing the Senior Notes (the “Indenture”) contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens and guarantees, investments, distributions to equityholders, asset sales and affiliate transactions. The Senior Notes were issued by BMC East, LLC, a 100% owned subsidiary of the Company, and are guaranteed by the Company and the other subsidiaries that guarantee the Credit Agreement. Each of the subsidiary guarantors is 100% owned, directly or indirectly, by the Company, and all guarantees are full and unconditional and joint and several. We were in compliance with all covenants under the Indenture as of September 30, ~~2017.~~2019.

Revolving credit agreement

On December 1, 2015, ~~in connection with the Merger,~~ the Company entered into ~~the Credit Agreement~~a senior secured credit agreement with Wells Fargo Capital Finance, as administrative agent, and certain other lenders. The Existing Credit Agreement, ~~as amended,~~ which includes the Revolver, ~~has an~~was amended on May 31, 2019 when the Company entered into the Third Amendment. The Third Amendment increased the aggregate commitment offrom $375.0 million ~~and~~to $425.0 million. The Credit Agreement has a letters of credit sublimit of $100.0 million. The Revolver matures at the earlier of (i) ~~December 1, 2020~~May 31, 2024 and (ii) ~~the date that is three months prior to the maturity of the Senior Notes, or~~ if the Senior Notes are refinanced or repaid, the date that is ~~three months~~91 days prior to the new maturity date of the replacement notes or other indebtedness that replaced or refinanced the Senior Notes. The Revolver is subject to an asset-based borrowing formula on eligible accounts receivable, credit card receivables and inventory, in each case reduced by certain reserves.

Borrowings under the Revolver bear interest, at our option, at either the Base Rate (which means the higher of (i) the Federal Funds Rate plus 0.5%, (ii) the LIBOR rate plus 1.0% or (iii) the prime rate) plus a Base Rate Margin (which ranges from 0.25% to ~~0.75%~~0.50% based on Revolver availability) or LIBOR plus a LIBOR Rate Margin (which ranges from 1.25% to ~~1.75%~~1.50% based on Revolver availability).

The Credit Agreement includes customary provisions for implementation of replacement rates for rate-based and LIBOR-based loans upon any phase-out of LIBOR. The fee on any outstanding letters of credit issued under the Revolver ranges from 0.75% to 1.25%, depending on whether the letters of credit are fully cash collateralized. The fee on the unused portion of the Revolver is 0.25%.

The Credit Agreement contains customary nonfinancial covenants, including restrictions on new indebtedness, issuance of liens, investments, distributions to equityholders, asset sales, affiliate transactions, merger transactions and ~~affiliate transactions.~~entering into unrelated businesses. The Credit Agreement includes a financial covenant that requires us to maintain a minimum Fixed Charge Coverage Ratio of 1.00:1:00, as defined therein. However, the covenant is only applicable if excess availability under the Credit Agreement is less than or equal to the greater of (i) ~~$33.3~~$37.7 million and (ii) 10% of the line cap, and remains in effect until excess availability has been greater than the greater of (i) ~~$33.3~~$37.7 million and (ii) 10% of the line cap for 30 consecutive days. While there can be no assurances, based upon our forecast, we do not expect the financial covenant to become applicable during the year ~~ended~~ending December 31, ~~2017.~~2019. We were in compliance with all covenants under the Credit Agreement as of September 30, ~~2017.~~2019.

We had no outstanding borrowings ~~of $51.8 million~~ with net availability of ~~$256.4~~$367.8 million as of September 30, ~~2017.~~2019. We had ~~$66.8~~$56.1 million in letters of credit outstanding under the Credit Agreement as of September 30, ~~2017.~~2019.

Contractual Obligations and Commercial Commitments

The Company was obligated under certain purchase commitments totaling approximately ~~$5.7~~$15.5 million at September 30, ~~2017~~2019 that are non-cancellable, enforceable and legally binding on us. These purchase commitments consist primarily of obligations ~~to purchase vehicles.~~for vehicle purchases and facility improvements.

Off-Balance Sheet Arrangements

At September 30, ~~2017~~2019 and December 31, ~~2016,~~2018, other than ~~operating leases and~~ letters of credit issued under the Credit Agreement, we had no material off-balance sheet arrangements with unconsolidated entities.

ITEM 3 QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes to the market risks as disclosed in the Company’s ~~2016~~2018 Annual Report on Form 10-K.

ITEM 4 CONTROLS AND PROCEDURES

Disclosure controls and procedures

Our management is responsible for establishing and maintaining disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These disclosure controls and procedures are designed to ~~ensure~~provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ~~ensure~~provide reasonable assurance that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

We have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q, with the participation of our Chief Executive Officer and Chief Financial Officer, as well as other key members of our management. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of September 30, ~~2017.~~

~~Changes~~2019 as a result of the previously identified material weakness in internal control over financial reporting described below.

~~There was no change~~Notwithstanding the material weakness described below, management has concluded that our condensed consolidated financial statements included in ~~our internal control over~~this Quarterly Report on Form 10-Q were not materially misstated and present fairly, in all material respects, the condensed consolidated financial ~~reporting during~~position, results of operations and cash flows of the ~~three months ended September 30, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.~~

~~Limitations~~registrant as of, and for the periods presented in ~~control systems~~this report.

The design of any system of control is based upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated objectives under all future events, no matter how remote, or that the degree of compliance with the policies or procedures may not deteriorate. Because of their inherent limitations, disclosure controls and procedures may not prevent or detect all misstatements. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Previously identified material weakness in internal control over financial reporting

In connection with the preparation of our condensed consolidated financial statements for the three and six months ended June 30, 2019, management identified that a former credit manager within one of our local operations violated our credit policy by intentionally misapplying certain customer payments, both within a single customer balance as well as across multiple customer balances, and created inappropriate debit memos, all with the intent to manipulate the aging of certain unpaid customer invoices. The inappropriate activities resulted in an immaterial understatement of our provision for doubtful accounts in previously issued annual and interim financial statements.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements would not be prevented or detected on a timely basis.

We identified a design deficiency with respect to effective controls over the approval and issuance of debit memos and the application of customer payments to accounts receivable balances, and inadequate segregation of duties over the ability to create debit memos and apply customer payments by certain employees responsible for establishing and monitoring the valuation of accounts receivable balances. Management concluded these deficiencies constituted a material weakness in our internal control over financial reporting.

The material weakness resulted in immaterial misstatements to our previously issued interim and annual consolidated financial statements impacting selling, general and administrative expenses and accounts receivable, net of allowances. We corrected for the Prior Period Misstatement by recording in the three months ended June 30, 2019 an out of period bad debt expense of approximately $4.3 million in selling, general and administrative expenses and a corresponding decrease to accounts receivable, net of allowances.

Remediation plan for material weakness

With the oversight of the Audit Committee of the Board of Directors, we are currently implementing actions to address the design deficiency in order to remediate the material weakness. The following describes the steps that we have taken to remediate the material weakness during the three months ended September 30, 2019:

We have restricted debit memo functionality within our primary ERP system by role and dollar limit authority, and have implemented additional monitoring and analytical controls performed by individuals who do not have conflicting access.

We have removed cash application access from our credit directors, and in markets where it is feasible, we have removed cash application access from our credit managers.

In markets where it is not feasible to remove cash application access from our credit managers due to resource limitations, we have implemented additional monitoring and analytical controls performed by individuals who do not have conflicting access.

We believe the measures described above will strengthen our internal control over financial reporting and remediate the identified material weakness. However, additional steps may be required and we may decide to take additional action to address control deficiencies or determine to modify certain of the remediation measures identified above. The material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time, which is expected to be by December 31, 2019, and management has concluded, through testing, that these controls are operating effectively.

Changes in internal control over financial reporting

Other than with respect to the remediation actions described above, there was no change in our internal control over financial reporting during the three months ended September 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1 LEGAL PROCEEDINGS

We are currently involved in various claims, legal proceedings and lawsuits incidental to the conduct of our business in the ordinary course. We are a defendant in various pending lawsuits, legal proceedings and claims arising from assertions of alleged product liability, warranty, casualty, construction defect, contract, tort, employment and other claims. We carry insurance in such amounts in excess of our self-insurance or deductibles as we believe to be reasonable under the circumstances although insurance may or may not cover any or all of our liabilities in respect of claims and lawsuits. We do not currently believe that the ultimate resolution of these matters will have a material adverse effect on our consolidated financial position, cash flows or operating results.

On August 30, 2017, Region 10 of the U.S. Environmental Protection Agency (the “EPA”) sent a notice of intent to us, alleging certain violations of the Clean Water Act with respect to industrial stormwater permitting regarding monitoring, inspections, benchmarks and record keeping at our Everett, Washington facility. The EPA has asserted that the alleged violations may subject us to administrative or civil penalties. We are in discussions with the EPA to explore a potential resolution of this matter. We are unable to predict the outcome of this matter, including potential administrative or civil penalties, remedial measures, or other relief, if any, or the potential impact on operations of the Everett facility, including increased capital or operational costs, if any.

ITEM 1A RISK FACTORS

There have been no material changes to our risk factors from the risk factors disclosed in our ~~2016~~2018 Annual Report on Form ~~10-K.~~ 10-K, as supplemented by the information in Part II, Item 1A in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2019 (“Second Quarter Form 10-Q”).

The risks described in our ~~2016~~2018 Annual Report on Form 10-K and Second Quarter Form 10-Q, in addition to the other information set forth in this Quarterly Report on Form 10-Q, are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

ITEM 2 UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

~~None.~~Issuer Purchases of Equity Securities

During November 2018, the Company’s board of directors authorized a $75.0 million share repurchase program, which was to expire on November 20, 2019.

Repurchases may be made at management’s discretion from time to time on the open market, subject to applicable laws, or through privately negotiated transactions. The repurchase program may be suspended or discontinued at any time. There were no repurchases during the three months ended September 30, 2019. As of September 30, 2019, the Company had approximately $55.7 million of capacity remaining under the current share repurchase authorization.
