The condensed consolidated balance sheet as of December 31, 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, 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, 2018 (“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.
Comprehensive income
Comprehensive income is equal to the net income for all periods presented.
Cash and 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 March 31,September 30, 2019 and December 31, 2018, the Company had cash equivalents of $136.0$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 waswere classified as a Level 1 or Level 2 measurementmeasurements 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 threenine months ended March 31,September 30, 2019, utilizing cash from operations, the Company repurchased 0.91.0 million shares at a weighted average price of $17.07$17.11 per share for a total cost of $15.7 million under the $75.0 million share repurchase program authorized by the Company’s board of directors in November 2018.$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 March 31,September 30, 2019, the Company had approximately $56.4$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 whichthat 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 February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2016-02, Leases, and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2016-02” or “Topic 842”). ASU 2016-02 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 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 March 31,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, 2020, with early adoption permitted beginning January 1, 2019. Modified retrospective application is required, with certain exceptions. The Company expects to adopt the standard on January 1, 20202020. The Company does not expect adoption of the standard to have a material impact on the Company’s allowance for financial instruments within the scope of the standard, including its trade receivables and contract assets. The Company continues to evaluate the impactdisclosure requirements of the standard on its consolidated financial statements.standard.
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 goodwill. The amount of a goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for the Company’s annual goodwill impairment test and any interim tests during the Company’s annual and interim periods beginning on January 1, 2020. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. Prospective application is required. The adoption of the standard is not expected to have a material impact on the Company’s consolidated financial statements.
In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement and issued subsequent amendments to the initial guidance to provide additional clarification on specific topics (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements by removing, modifying and adding certain disclosure requirements in ASC 820. ASU 2018-13 is effective for the Company’s annual and interim periods beginning on January 1, 2020, with early adoption permitted. Certain disclosures in ASU 2018-13 are required to be applied prospectively, while others require retrospective application. The Company is evaluating the impactadoption of the standard is not expected to have a material impact on itsthe Company’s consolidated financial statements.
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.


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

The preliminary purchase price, in aggregate, for the 2019 Acquisitions was $54.5$90.9 million. The preliminary purchase price includes holdbacks which, after certain post-closing adjustments, require the Company to pay $5.5 million, which includes an initial holdback of $2.5 million duein aggregate, to the sellers of Barefoot, Kingston Lumber, Heritage One and Colorado Fasteners one year from the respective closing date.dates. The holdback amountamounts 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 $12.8$20.4 million, customer relationship intangible assets of $23.3$33.1 million, a non-compete agreement intangible assetassets of $0.2$0.5 million, accounts receivable of $12.1$22.1 million, inventory of $7.5$14.7 million and property and equipment of $2.3$5.6 million, as well as other operating assets and liabilities. The customer relationship and non-compete agreement intangible assets have a weighted average useful life of 9 years and 24 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 is expected to be deductible for tax purposes.


The purchase price allocationallocations for the 2019 Acquisitions isare preliminary and based upon all information available to the Company at the present time, and isare 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, 2018, Barefoot and Locust Lumberthe 2019 Acquisitions generated net sales, in aggregate, of approximately $105$199 million. The Company incurred transaction costs of $0.3$0.2 million and $0.5 million for the three and nine months ended March 31,September 30, 2019, respectively, related to the 2019 Acquisitions.

The customer relationship intangible asset has a useful life of 9 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.


Net sales and estimated pre-tax earnings for Shone Lumber included in the unaudited condensed consolidated statements of operations for the three months ended September 30, 2018 were $18.7 million and $0.8 million, respectively.

5.    Leases


Adoption of Topic 842
On January 1, 2019, the Company 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 March 31,September 30, 2018 has not been adjusted and continues to be reported under ASC 840, Leases (“ASC 840”). The Company elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed the Company to carry forward its identification of 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 March 31,September 30, 2019.




Beginning January 1, 2019, the Company has recognized ROU assets and lease liabilities for the Company’s operating leases on its unaudited condensed consolidated 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 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 non-cancellablenoncancellable 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, we use the Company’sCompany 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.

As permitted by TopicASC 606, Revenue from Contracts with Customers, the Company has elected not to disclose the value of unsatisfied performance obligations, as the 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 March 31,September 30, 2019 and December 31, 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 March 31,September 30, 2019 and December 31, 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 March 31,September 30, 2019, the Company’s effective tax rate was 22.8%28.2% and 24.9%, respectively, which varied from the federal statutory rate of 21% primarily due to state income taxes and the Income Tax Adjustment. Excluding the Income Tax Adjustment, the Company’s effective tax expense.rate was 24.7% and 23.6% for the three and nine months ended September 30, 2019, respectively. For the three and nine months ended March 31,September 30, 2018, the Company’s effective tax rate was 23.2%23.4% and 23.3%, respectively, which varied from the federal statutory rate of 21% primarily due to state income tax expense offset by excess tax windfall benefits from stock compensation.taxes.


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. As of December 31, 2018, the Company had accrued $3.0 million in relation to pending litigation that was recorded during the year ended December 31, 2017. During the threenine months ended March 31,September 30, 2019, the Company paid $2.8 million to settle the matter.

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 March 31,September 30, 2019 and 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.

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 March 31,September 30, 2019 and 2018 are presented below:

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, overall economic conditions. Unfavorable economic changes, both nationally and locally in our markets, could adversely affect consumer spending, result in decreased demand for homes and 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, declinedincreased approximately 3.8%5.1% for the three months ended March 31,September 30, 2019 as compared to the same period in the prior year.


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.

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.
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. For further discussion of the impact of mix of products sold on historical periods, 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: single-family homebuilders, remodeling contractors and multi-family, commercial and 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 our other primary customer types can vary based on a variety of factors.


Seasonality
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 decrease in net sales in our lumber and lumber sheet goods product category was primarily related to price deflation that began in the second half of 2018. The increase in net sales in our millwork, doors and windows product category was primarily related to the 2019 Acquisitions and other organic growth.
Cost of sales
For the three months ended September 30, 2019, cost of sales decreased $39.5 million, or 5.3%, to $709.5 million from $749.0 million during the three months ended September 30, 2018.

Revolving credit agreement

The Existing Credit Agreement, which includes the Revolver, has anwas amended on May 31, 2019 when the Company entered into the Third Amendment. The Third Amendment increased the aggregate commitment offrom $375.0 million andto $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, 2020May 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 months91 days prior to the new maturity date of the replacement notes or other indebtedness that replaced or refinanced the Senior Notes).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 endedending December 31, 2019. We were in compliance with all covenants under the Credit Agreement as of March 31,September 30, 2019.
We had no outstanding borrowings with net availability of $317.7$367.8 million as of March 31,September 30, 2019. We had $56.1 million in letters of credit outstanding under the Credit Agreement as of March 31,September 30, 2019.

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 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 ensureprovide 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 ensureprovide 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 March 31, 2019.September 30, 2019 as a result of the previously identified material weakness in internal control over financial reporting described below.
Notwithstanding the material weakness described below, management has concluded that our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q were not materially misstated and present fairly, in all material respects, the condensed consolidated financial position, results of operations and cash flows of the registrant as of, and for the periods presented in 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
ThereOther 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 March 31,September 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
