These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of December 31, 2018 and 2017 and for each of the three years in the period ended December 31, 2018 included in the Annual Report of Trex Company, Inc. on Form
10-K,
as filed with the U.S. Securities and Exchange Commission.

3. | RECENTLY ADOPTED ACCOUNTING STANDARDS

In June 2018, the FASB issued ASU No.
2018-07,
“
Compensation – Stock Compensation (Topic 718)
.” The ASU expands the scope of Topic 718, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods or services. The ASU supersedes Subtopic
505-50,
“
Equity—Equity-Based Payment to Non-Employees
.” Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU was effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company adopted the guidance on January 1, 2019. Adoption did not have an impact on the Company’s financial condition or results of operations.
In February 2016, the FASB issued ASU No.
2016-02,
“
Leases (Topic 842),
” and issued subsequent amendments to the initial guidance in January 2018 within ASU No.
2018-01,
in July 2018 within ASU Nos.
2018-10
and
2018-11,
in December 2018 within ASU No.
2018-20,
and in March 2019 within ASU No.
2019-01
(collectively, the standard). The standard requires lessees to recognize operating leases on the balance sheet as a
right-of-use
asset and a lease liability. The liability is equal to the present value of the lease payments over the remaining lease term. The asset is based on the liability, subject to certain adjustments. Operating leases result in straight-line expense. The Company adopted the standard on January 1, 2019, and elected the transition method of adoption, which allowed the Company to apply the standard as of the beginning of the period of adoption. The Company opted to elect the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs, and certain other practical expedients, including the use of hindsight to determine the lease term for existing leases and in assessing impairment of the
right-of-use
asset, and the exception for short-term leases. For its current classes of underlying assets, the Company did not elect the practical expedient under which the lease components would not be separated from the nonlease components. Nonlease components include certain maintenance services provided by the lessor and the related consideration is specified on a stand-alone basis in the applicable lease agreements. Adoption of the standard had a significant impact on the Company’s condensed consolidated balance sheet due to the recognition of a
right-of-use
asset and lease liability of $45.8 million and $47.2 million, respectively, upon adoption. As the Company’s leases do not provide an implicit rate that can be readily determined, the Company used its incremental borrowing rate based on the information available at the implementation date in determining the present value of lease payments.

4. | NEW ACCOUNTING STANDARDS NOT YET ADOPTED

In August 2018, the FASB issued ASU No.
2018-15,
“
Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of FASB Emerging Issues Task Force)”
. The new guidance aligns the requirements for capitalizing implementation costs in a cloud computing arrangement service contract with the requirements for capitalizing implementation costs incurred for an
internal-use
software license. Under that model, implementation costs are capitalized or expensed depending on the nature of the costs and the project stage during which they are incurred. Capitalized implementation costs are amortized over the term of the associated hosted cloud computing arrangement service contract on a straight-line basis, unless another systematic and rational basis is more representative of the pattern in which the entity expects to benefit from its right to access the hosted software. Capitalized implementation costs would then be assessed for impairment in a manner similar to long-lived assets. The new guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. Entities can choose to adopt the new guidance either prospectively to eligible costs incurred on or after the date the guidance is first applied or retrospectively. The Company intends to adopt the guidance on January 1, 2020, and
does not believe adoption will have a material impact on its financial condition or results of operations.
In January 2017, the FASB issued ASU No.
2017-04,
“
Intangibles—Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment
”. The guidance removes Step 2 of the goodwill impairment test and eliminates the need to determine the fair value of individual assets and liabilities to measure goodwill impairment. 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. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The guidance will be applied prospectively, and is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed on testing dates after January 1, 2017. The Company intends to adopt the guidance on January 1, 2020. The Company continues to evaluate the guidance and does not believe adoption will have a material impact on its financial condition or results of operations.
In June 2016, the FASB issued ASU
2016-13,
“
Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses in Financial Instruments,
” and issued subsequent amendments to the initial guidance in November 2018 within ASU No.
2018-09,
April 2019 within ASU No.
2019-04,
and May 2019 within ASU No.
2019-05.
The ASU amends the guidance on the impairment of financial instruments and adds an impairment model, known as the current expected credit loss (CECL) model. The CECL model requires an entity to recognize its current estimate of all expected credit losses, rather than incurred losses, and applies to trade receivables and other receivables. The CECL model is designed to capture expected credit losses through the establishment of an allowance account, which will be presented as an offset to the amortized cost basis of the related financial asset. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and is applied using the modified-retrospective approach. The Company intends to adopt the guidance on January 1, 2020. The Company continues to evaluate the guidance and does not believe adoption will have a material impact on its financial condition or results of operations.

Table of Contents
The Company utilizes the LIFO method of accounting related to its Trex Residential wood-alternative decking and residential railing products, which generally provides for the matching of current costs with current revenues. However, under the LIFO method, reductions in annual inventory balances cause a portion of the Company’s cost of sales to be based on historical costs rather than current year costs (LIFO liquidation). Reductions in interim inventory balances expected to be replenished by
year-end
do not result in a LIFO liquidation. Accordingly, interim LIFO calculations are based, in part, on management’s estimates of expected
year-end
inventory levels and costs which may differ from actual results. Since inventory levels and costs are subject to factors beyond management’s control, interim results are subject to the final
year-end
LIFO inventory valuation. As of June 30, 2019, management estimates that interim inventory balances will be replenished by
year-end
and there were
no
LIFO inventory liquidations or related impact on cost of sales in the six months ended June 30, 2019.
Inventories valued at lower of cost (FIFO method) and net realizable value were $1.9 million at June 30, 2019 and $2.3 million at December 31, 2018, consisting primarily of raw materials. The Company utilizes the FIFO method of accounting related to its
Trex Commercial
architectural railing and staging systems for the commercial and multi-family market.

9. | DEBT

The Company’s outstanding debt consists of a revolving credit facility.
Revolving Credit Facility
On January 12, 2016, the Company entered into a Third Amended and Restated Credit Agreement, as amended, with Bank of America, N.A. as Lender, Administrative Agent, Swing Line Lender and Letter of Credit Issuer, and certain other lenders including Citibank, N.A., Capital One, N.A., and SunTrust. The Third Amended Credit Agreement, as amended, provides the Company with one or more revolving loans in a collective maximum principal amount of $250 million from January 1 through June 30 of each year, and a maximum principal amount of $200 million from July 1 through December 31 of each year throughout the term, which ends
January 12, 2021
.
The Company had
no
outstanding borrowings under its revolving credit facility and remaining available borrowing capacity of $250 million at June 30, 2019.
Compliance with Debt Covenants and Restrictions
The Company’s ability to make scheduled principal and interest payments, borrow and repay amounts under any outstanding revolving credit facility and continue to comply with any loan covenants depends primarily on the Company’s ability to generate sufficient cash flow from operations.
As of June 30, 2019, the Company was in compliance with all of the covenants contained in its debt agreements. Failure to comply with the loan covenants might cause lenders to accelerate the repayment obligations under the credit facility, which may be declared payable immediately based on a default.

10. | LEASES

The Company leases office space, storage warehouses and certain plant equipment under various operating leases. The Company determines if an arrangement is a lease at inception. The arrangement is a lease if it conveys the right to the Company to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Operating leases are included in operating lease
right-of-use
(ROU) assets, accrued expenses and other current liabilities, and operating lease liabilities in the condensed consolidated balance sheets. Operating leases with an initial term of
12 months or less
are not included in the condensed consolidated balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases 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 lease payments. The Company gives consideration to instruments with similar characteristics when calculating its incremental borrowing rate. The Company’s operating leases have remaining lease terms of 1 year to 10 years. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

For the six months ended June 30, 2019, total operating lease cost was $4.2 million. The weighted average remaining lease term and weighted average discount rate at June 30, 2019 were 6.8 years and 3.67%, respectively.

Stock Repurchase Programs
On February 16, 2018, the Board of Directors adopted a stock repurchase program of up to 5.8 million shares of the Company’s outstanding common stock (Stock Repurchase Program). As of
June 30, 2019,
the Company had repurchased 709,461 shares of the Company’s outstanding common stock under the Stock Repurchase Program.

13. | REVENUE FROM CONTRACTS WITH CUSTOMERS

Topic 606 provides a single, comprehensive model for revenue recognition arising from contracts with customers. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when or as the Company satisfies the performance obligation. Revenue is recognized at an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring control of the goods or services to a customer.
Trex Residential Products
Trex Residential principally generates revenue from the manufacture and sale of its high performance, low maintenance composite decking and residential railing products and accessories. Substantially all of its revenues are from contracts with customers, which are purchase orders of short-term duration of less than one year. Its customers, in turn, sell primarily to the residential market, which includes replacement, remodeling and new construction related to outdoor living products. Trex Residential satisfies its performance obligations at a point in time. The shipment of each product is a separate performance obligation as the customer is able to derive benefit from each product shipped and no performance obligation remains after shipment. Upon shipment of the product, the customer obtains control over the distinct product and Trex Residential satisfies its performance obligation. Any performance obligation that remains unsatisfied at the end of a reporting period is part of a contract that has an original expected duration of one year or less. Any variable consideration related to the unsatisfied performance obligation is allocated wholly to the unsatisfied performance obligation and recognized when the product ships and the performance obligation is satisfied.
For each product shipped, the transaction price by product is specified in the purchase order. The Company recognizes revenue on the transaction price less any amount offered under a sales incentive program. The Company recognizes an account receivable (contract asset) for the amount of revenue recognized as it has an unconditional right to consideration at the time of shipment and payment from the customer is due based solely on the passage of time. The Company receives payments from its customers based on the payment terms applicable to each individual contract and the customer pays in accordance with the billing terms specified in the purchase order, which is less than one year. The related accounts receivables are included in “
Accounts receivable, net
” in the Condensed Consolidated Balance Sheets.

Table of Contents
Trex Residential may offer various sales incentive programs throughout the year. It estimates the amount of sales incentive to allocate to each performance obligation, or product shipped, based on direct sales to the customer. The estimate is updated each reporting period and any changes are allocated to the performance obligations on the same basis as at inception. Changes in estimate allocated to a previously satisfied performance obligation are recognized as a reduction of revenue in the period in which the change occurs under the cumulative
catch-up
method. In addition to sales incentive programs, Trex Residential may offer a payment discount. It estimates the payment discount that it believes will be taken by the customer based on prior history.
Trex Residential pays commissions to certain employees. However, the sales commissions are not directly attributable to identifiable contracts, are discretionary in nature and are based on other factors not related to obtaining a contract, such as individual performance, profitability of the entity, annual sales targets, etc. These costs are included in selling, general and administrative expenses as incurred. Trex Residential does not grant contractual product return rights to customers other than pursuant to its assurance product warranty (see related disclosure on product warranties in Note 18, “
Commitments and Contingencies
”). Trex Residential accounts for all shipping and handling fees invoiced to the customer in net sales and the related costs in cost of sales.
Trex Commercial Products
Trex Commercial generates revenue from the manufacture and sale of its modular and architectural railing and staging systems. All of its revenues are from fixed-price contracts with customers. Trex Commercial contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contract and is, therefore, not distinct.
Trex Commercial satisfies its performance obligation over time as work progresses because control is transferred continuously to its customers. Revenue and estimated profit is recognized over time based on the proportion of actual costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying the performance obligation. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Incurred costs include all direct material, labor, subcontract and certain indirect costs. The Company reviews and updates its estimates regularly and recognizes adjustments in estimated profit on contracts under the cumulative
catch-up
method. Under this method, the impact of the adjustment on revenue and estimated profit to date on a contract is recognized in the period the adjustment is identified. Revenues and profits in future periods are recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified. During the six months ended June 30, 2019, no adjustment to any one contract was material to the Company’s Condensed Consolidated Financial Statements. In accordance with ASC
606-10-50-15,
the Company discloses only the transaction price allocated to its remaining performance obligations on contracts with an original duration greater than one year, which was $48.2 million as of June 30, 2019. The Company will recognize this revenue as contracts are completed, which is expected to occur within the next 24 months.
The Company recognizes an account receivable (contract asset) for satisfied performance obligations as it has an unconditional right to consideration and payment from the customer is due based solely on the passage of time. The Company receives payments from its customers on the accounts receivable based on the payment terms applicable to each individual contract and the customer pays in less than one year. Accounts receivables are included in “
Accounts receivable, net
” in the Condensed Consolidated Balance Sheets.
In addition, the timing of revenue recognition, billings and cash collections may result in revenues in excess of billings and contract retainage (contract assets), and billings in excess of revenues and customer deposits (contract liabilities) in the Condensed Consolidated Balance Sheet. These assets and liabilities are reported on a
contract-by-contract
basis at the end of each reporting period in prepaid expenses and other assets (contract assets), and accrued expenses and other liabilities (contract liabilities). These assets and liabilities and changes in these assets and liabilities were not material as of and for the six months ended June 30, 2019.
Trex Commercial pays sales commissions that are directly attributable to identifiable contracts to certain of its employees. If the amortization period of the commission is one year or less then the Company recognizes the commission expense as incurred. Otherwise, the Company capitalizes the commission and amortizes it on a straight-line basis over the life of the contract. Trex Commercial does not grant contractual product return rights to customers other than pursuant to its assurance product warranty. All shipping and handling fees invoiced to the customer are included in net sales and the related costs are included in cost of sales.

14. | STOCK-BASED COMPENSATION

The Company has one stock-based compensation plan, the 2014 Stock Incentive Plan (Plan), approved by the Company’s stockholders in April 2014. The Plan amended and restated in its entirety the Trex Company, Inc. 2005 Stock Incentive Plan. The Plan was subsequently amended and restated by the Company’s Board of Directors in May 2014 and May 2018. The Plan is administered by the Compensation Committee of the Company’s Board of Directors. Stock-based compensation is granted to officers, directors and certain key employees in accordance with the provisions of the Plan. The Plan provides for grants of stock options, restricted stock, restricted stock units, stock appreciation rights (SARs), and unrestricted stock. The total aggregate number of shares of the Company’s common stock that may be issued under the Plan is 12,840,000 and as of June 30, 2019, the total number of shares available for future issuance are 5,761,081.

The fair value of each SAR is estimated on the date of grant using a
Black-Scholes option-pricing formula
. For SARs issued in the six months ended June 30, 2019 and 2018 the data and assumptions shown in the following table were used:

|  | Six Months Ended June 30, 2019 |  |  | Six Months Ended June 30, 2018 |
Weighted-average fair value of grants |  | $ | 29.56 |  |  | $ | 22.09 |

Expected term (years) |  |  | 5 |  |  |  | 5 |
Expected volatility |  |  | 39.1 | % |  |  | 40.4 | %

The Company recognizes stock-based compensation expense ratably over the period from the grant date to the earlier of: (1) the vesting date of the award, or (2) the date the grantee is eligible to retire without forfeiting the award. For performance-based restricted stock and performance-based restricted stock units, expense is recognized ratably over the performance and vesting period of each tranche based on management’s judgment of the ultimate award that is likely to be paid out based on the achievement of the predetermined performance measures. For the employee stock purchase plan, compensation expense is recognized related to the discount on purchases. Stock-based compensation expense in included in “Selling, general and administrative expenses” in the Condensed Consolidated Statements of Comprehensive Income. The following table summarizes the Company’s stock-based compensation expense (in thousands):

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |

15. | INCOME TAXES

The Company’s effective tax rate for the six months ended June 30, 2019 and 2018 was 22.7% and 23.7%, respectively, which resulted in expense of $19.7 million and $24.8 million, respectively. The decrease of 1.0% in the effective tax rate was primarily due to a current year increase in excess tax benefits from the exercise of share-based payments against lower year-over-year income before taxes.
During the six months ended June 30, 2019 and 2018, the Company realized $2.6 million and $2.0 million, respectively, of excess tax benefits from stock-based awards and recorded a corresponding benefit to income tax expense.
The Company analyzes its deferred tax assets each reporting period, considering all available positive and negative evidence in determining the expected realization of those deferred tax assets. As of June 30, 2019, the Company maintains a valuation
allowance of $3.0 million against deferred tax assets primarily related to state tax credits it estimates will expire before they are realized.

The Company operates in multiple tax jurisdictions and, in the normal course of business, its tax returns are subject to examination by various taxing authorities. Such examinations may result in future assessments by these taxing authorities, and the Company accrues a liability when it believes that it is more likely than not that benefits of tax positions will not be realized. The Company believes that adequate provisions have been made for all tax returns subject to examination. As of June 30, 2019, for certain tax jurisdictions tax years 2015 through 2018 remain subject to examination.
The Company’s returns filed with the state of Oregon for the tax years 2015 through 2017 are currently under examination. No material adjustments are expected as a result of the audit.
Sales made to foreign distributors are not taxable in any foreign jurisdiction as the Company does not have a taxable presence in any foreign jurisdiction.

16. | SEGMENT INFORMATION

The Company operates in
two
reportable segments:

| • | Trex Residential manufactures wood-alternative decking and residential railing and related products marketed under the brand name Trex ® . Trex Residential products are sold to distributors and home centers for final resale primarily to the residential market, which includes replacement, remodeling and new construction related to outdoor living products. Trex Residential net sales were $358.9 million and $344.4 million in the six months ended June 30, 2019 and 2018, respectively.

| • | Trex Commercial designs, engineers, and markets modular and architectural railing and staging systems for the commercial and multi-family market, including sports stadiums and performing arts venues. Trex Commercial products are marketed to architects, specifiers, contractors, and others doing business within the commercial and multi-family market. Trex Commercial net sales were $27.1 million and $33.5 million in the six months ended June 30, 2019 and 2018, respectively.

The Company’s reportable segments have been determined in accordance with its internal management structure, which is organized based on residential and commercial sales activities. The Company evaluates performance of
each
segment primarily based on net sales and earnings before interest, taxes, depreciation and amortization (EBITDA). The Company uses net sales to assess performance and allocate resources as this measure represents the amount of business the segment engaged in during a given period of time, is an indicator of market growth and acceptance of segment products, and represents the segment’s customers’ spending habits along with the amount of product the segment sells relative to its competitors. The Company uses EBITDA to assess performance and allocate resources because it believes that EBITDA facilitates performance comparison between the segments by eliminating interest, taxes, and depreciation and amortization charges to income. The below segment data for the three and six months ended June 30, 2019 and 2018 includes data for Trex Residential and Trex Commercial (in thousands):

17. | SEASONALITY

The operating results for Trex Residential have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex Residential has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs. The operating results for Trex Commercial have not historically varied from quarter to quarter as a result of seasonality. However, they are driven by the timing of individual projects, which may vary each quarterly period.

18. | COMMITMENTS AND CONTINGENCIES

Product Warranty
The Company warrants that its decking and residential railing products will be free from material defects in workmanship and materials for warranty periods ranging from 10 years to 25 years, depending on the product and its use. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price. The Company continues to receive and settle claims for products manufactured at its Nevada facility prior to 2007 that exhibit surface flaking and maintains a warranty reserve to provide for the settlement of these claims. Estimating the warranty reserve for surface flaking claims requires management to estimate (1) the number of claims to be settled with payment and (2) the average cost to settle each claim.
16
Table of Contents
To estimate the number of claims to be settled with payment, the Company utilizes actuarial techniques to quantify both the expected number of claims to be received and the percentage of those claims that will ultimately require payment (collectively, elements). Estimates for these elements are quantified using a range of assumptions derived from claim count history and the identification of factors influencing the claim counts. The cost per claim varies due to a number of factors, including the size of affected decks, the availability and type of replacement material used, the cost of production of replacement material and the method of claim settlement.
The Company monitors surface flaking claims activity each quarter for indications that its estimates require revision. Typically, a majority of surface flaking claims received in a year are received during the summer outdoor season, which spans the second and third quarters. It has been the Company’s practice to utilize the actuarial techniques discussed above during the third quarter, after a significant portion of all claims has been received for the fiscal year and variances to annual claims expectations are more meaningful. The number of incoming claims received in the six months ended June 30, 2019 was lower
than the Company’s expectations and lower than the number of claims received in the six months ended June 30, 2018, continuing the historical year-over-year decline in incoming claims. Average settlement cost per claim experienced in the six months ended June 30, 2019 was
higher
than the Company’s expectations and higher than the average settlement cost per claim experienced in the six months ended June 30, 2018. The Company believes its reserve at June 30, 2019 is sufficient to cover future surface flaking obligations and no adjustments were required in the current quarter.
The Company’s analysis is based on currently known facts and a number of assumptions, as discussed above, and current expectations. Projecting future events such as the number of claims to be received, the number of claims that will require payment and the average cost of claims could cause actual warranty liabilities to be higher or lower than those projected, which could materially affect the Company’s financial condition, results of operations or cash flows. The Company estimates that the annual number of claims received will continue to decline over time and that the average cost per claim will increase slightly, primarily due to inflation. If the level of claims received or average cost per claim differs materially from expectations, it could result in additional increases or decreases to the warranty reserve and a decrease or increase in earnings and cash flows in future periods. The Company estimates that a 10% change in the expected number of remaining claims to be settled with payment or the expected cost to settle claims may result in approximately a $2.2 million change in the surface flaking warranty reserve.

Legal Matters
The Company has lawsuits, as well as other claims, pending against it which are ordinary routine litigation and claims incidental to the business. Management has evaluated the merits of these lawsuits and claims, and believes that their ultimate resolution will not have a material effect on the Company’s consolidated financial condition, results of operations, liquidity or
competitive position.

OVERVIEW
Operations and Products:
Trex Company, Inc. currently operates in two reportable segments: Trex Residential Products (Trex Residential) and Trex Commercial Products (Trex Commercial). The Company is focused on using renewable resources within both our Residential and Commercial segments.
Trex Residential
is the world’s largest manufacturer of high-performance composite decking and residential railing products, which are marketed under the brand name Trex
®
and manufactured in the United States. We offer a comprehensive set of aesthetically appealing and durable,
low-maintenance
product offerings in the decking, residential railing, fencing, steel deck framing, and outdoor lighting categories. A majority of the products are
eco-friendly
and leverage recycled materials to the extent possible. Trex Residential decking is made in a proprietary process that combines reclaimed wood fibers and recycled polyethylene film, making Trex one of the largest recyclers of plastic film in North America. In addition to resisting fading and surface staining, Trex Residential products require no sanding and sealing, resist moisture damage, provide a splinter-free surface and do not require chemical treatment against rot or insect infestation. Combined, these aspects yield significant aesthetic advantages and lower maintenance than wood decking and railing and ultimately render Trex products less costly than wood over the life of the deck. Special characteristics (including resistance to splitting, the ability to bend, and ease and consistency of machining and finishing) facilitate installation, reduce contractor call-backs and afford consumers a wide range of design options. Trex Residential products are sold to distributors and home centers for final resale primarily to the residential market.
Trex offers the following products through Trex Residential:

Decking |  | Our principal decking products are Trex Transcend ® , Trex Enhance ® and Trex Select ® . Late in 2018, we re-engineered our Enhance line to provide homeowners with a high-performance, lower-cost deck board designed to compete more directly with wood. Differentiating the Enhance collection is a scalloped profile that is lighter weight for easier handling and installation. Our eco-friendly composite decking products are comprised of a blend of 95 percent reclaimed wood fibers and recycled plastic film and feature a protective polymer shell for enhanced protection against fading, staining, mold and scratching. We also offer Trex Hideaway ® , a hidden fastening system for grooved boards.

Highlights for the three and six months ended June 30, 2019:

| • | Repurchase of 125,151 shares of our outstanding common stock during the three months ended June 30, 2019 under our Stock Repurchase Program, for a total of 709,461 shares repurchased under the program to date.

| • | Net cash provided by operating activities of $43.1 million during the six months ended June 30, 2019 compared to net cash used in operating activities of $1.7 million during the six months ended June 30, 2018.

| • | New capital expenditure program to increase production capacity at the Trex Residential facilities in Winchester, Virginia, and Fernley, Nevada, and projected at approximately $200 million between now and 2021.

Net Sales
. Net sales consist of sales and freight, net of discounts. The level of net sales is principally affected by sales volume and the prices paid for Trex products. Trex Residential operating results have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home and commercial improvement and residential and commercial construction and can shift demand for our products to a later period. As part of our normal business practice and consistent with industry practices, we have historically provided our distributors and dealers of our Trex Residential products incentives to build inventory levels before the start of the prime deck-building season to ensure adequate availability of our product to meet anticipated seasonal consumer demand and to enable production planning. These incentives include payment discounts and favorable payment terms. In addition, we offer price discounts or volume rebates on specified products and other incentives based on increases in purchases as part of specific promotional programs. The timing of sales incentive programs can significantly impact sales, receivables and inventory levels during the offering period. However, the timing and terms of the majority of our programs are generally consistent from year to year. In addition, the operating results for Trex Commercial are driven by the timing of individual projects, which may vary each quarterly period.
Gross Profit.
Gross profit represents the difference between net sales and cost of sales. Cost of sales consists of raw material costs, direct labor costs, manufacturing costs, subcontract costs and freight. Raw material costs generally include the costs to purchase and transport reclaimed wood fiber, reclaimed polyethylene, pigmentation for coloring our products, and commodities used in the production of railing and staging. Direct labor costs include wages and benefits of personnel engaged in the manufacturing process. Manufacturing costs consist of costs of depreciation, utilities, maintenance supplies and repairs, indirect labor, including wages and benefits, and warehouse and equipment rental activities.
Product Warranty.
We warrant that our Trex Residential products will be free from material defects in workmanship and materials for warranty periods ranging from 10 years to 25 years, depending on the product and its use. If there is a breach of such warranties, we have an obligation either to replace the defective product or refund the purchase price. We also warrant our Trex Commercial products for 1 to 3 years.
We continue to receive and settle claims for decking products manufactured at our Nevada facility prior to 2007 that exhibit surface flaking and maintain a warranty reserve to provide for the settlement of these claims. We monitor surface flaking claims activity each quarter for indications that our estimates require revision. Typically, a majority of surface flaking claims received in a fiscal year are received during the summer outdoor season, which spans the second and third fiscal quarters. It has been our practice to utilize actuarial techniques during the third quarter, after a significant portion of all claims has been received for the fiscal year and variances to annual claims expectations are more meaningful. Our actuarial analysis is based on currently known facts and a number of assumptions. Projecting future events such as the number of claims to be received, the number of claims that will require payment and the average cost of claims could cause the actual warranty liabilities to be higher or lower than those projected, which could materially affect our financial condition, results of operations or cash flows. The number of incoming claims received in the six months ended June 30, 2019 was lower than our expectations and lower than the claims received in the six months ended June 30, 2018, continuing the historical year-over-year decline in incoming claims. Average settlement cost per claim experienced in the six months ended June 30, 2019 was higher than our expectations and higher than the average settlement cost per claim experienced in the six months ended June 30, 2018. We believe that our reserve at June 30, 2019 is sufficient to cover future surface flaking obligations.

Selling, General and Administrative Expenses.
The largest component of selling, general and administrative expenses is personnel related costs, which includes salaries, commissions, incentive compensation, and benefits of personnel engaged in sales and marketing, accounting, information technology, corporate operations, research and development, and other business functions. Another component of selling, general and administrative expenses is branding and other sales and marketing costs, which are used to build brand awareness. These costs consist primarily of advertising, merchandising, and other promotional costs. Other general and administrative expenses include professional fees, office occupancy costs attributable to the business functions previously referenced, and consumer relations expenses. As a percentage of net sales, selling, general and administrative expenses may vary from quarter to quarter due, in part, to the seasonality of our business.
RESULTS OF OPERATIONS
Below is our discussion and analysis of our operating results and material changes in our operating results for the three months ended June 30, 2019 (2019 quarter) compared to the three months ended June 30, 2018 (2018 quarter), and for the six months ended June 30, 2019 (2019
six-month
period) compared to the six months ended June 30, 2018 (2018

Total net sales |  | $ | 206,453 |  |  | $ | 206,692 |  |  | $ | (239 | ) |  |  | (0.1 | )%
Trex Residential net sales |  | $ | 193,468 |  |  | $ | 189,201 |  |  | $ | 4,267 |  |  |  | 2.3 | %
Trex Commercial net sales |  | $ | 12,985 |  |  | $ | 17,491 |  |  | $ | (4,506 | ) |  |  | (25.8 | )%

Total net sales decreased slightly by 0.1% in the 2019 quarter compared to the 2018 quarter. Net sales of Trex Residential decking were constrained due to supply issues, which were primarily caused by new product startup inefficiencies late in 2018, through the first quarter of 2019 and, to a much lesser extent, in the second quarter of 2019 related to our new Enhance product. These supply issues resulted in lower throughput and finished goods inventory than was needed to support market demand. Trex Residential net sales were positively impacted by strength in the residential remodeling sector, our marketing programs aimed at taking market share from wood and the healthy demand across our full suite of outdoor living products. The increase in Trex Residential net sales was offset by a 25.8% decrease in Trex Commercial net sales due to reduced volume.

Gross profit as a percentage of net sales, gross margin, was 40.4% in the 2019 quarter compared to 44.1 % in the 2018 quarter. Gross margin for Trex Residential and Trex Commercial in the 2019 quarter totaled 41.7% and 21.4%, respectively, compared to 45.9% and 24.6%, respectively, in the 2018 quarter. The decrease in total gross margin in the 2019 quarter was primarily due to a decrease in Trex Residential gross profit resulting from startup costs on our new Enhance product, which were much improved compared to the first quarter, and the modification late in the first quarter to the profile of our new Enhance product that improved manufacturability but added material and increased cost. During March and through the 2019 quarter, we made a number of changes to improve throughput. As a result, our production rates returned to planned levels and associated operating inefficiencies have been reduced.

The $2.2 million increase in selling, general and administrative expenses in the 2019 quarter compared to the 2018 quarter resulted primarily from an increase of $1.6 million increase in branding and advertising spend in support of our market growth programs, $1.3 million in personnel related expenses, primarily related to executive severance benefits, and $0.2 million in research and development expenses. The increases were offset by a $1.2 million decrease in amortization expense due to the full amortization of intangible assets acquired as part of the SC Company acquisition in July 2017.

The effective tax rate for the 2019 quarter of 25.2% was unchanged from the effective tax rate for the 2018 quarter. The decrease in income taxes was due to lower year-over-year income before income taxes.

1 | EBITDA represents net income before interest, income taxes, depreciation and amortization. EBITDA is not a measurement of financial performance under accounting principles generally accepted in the United States (GAAP). We have included data with respect to EBITDA because management evaluates the performance of its reportable segments using several measures, including EBITDA. Management considers EBITDA to be an important supplemental indicator of our core operating performance because it eliminates interest, taxes, and depreciation and amortization charges to net income or loss. For these reasons, management believes that EBITDA provides important information regarding the operating performance of the Company’s reportable segments.

The Company uses EBITDA to assess performance as it believes EBITDA facilitates performance comparison between its reportable segments by eliminating interest, income taxes, and depreciation and amortization charges to income. Total EBITDA decreased 17.7% to $51.1 million for the 2019 quarter compared to $62.2 million for the 2018 quarter. The decrease was driven by a decrease in Trex Residential and Trex Commercial gross margins of 4.2% and 3.2%, respectively, and a decrease in net sales volume at Trex Commercial.

Trex Commercial net sales |  | $ | 27,077 |  |  | $ | 33,498 |  |  | $ | (6,421 | ) |  |  | (19.2 | )%

The 2.2% increase in total net sales in the 2019
six-month
period compared to the 2018
six-month
period was due primarily to volume growth at Trex Residential for both our legacy and new residential decking and railing products. Net sales of Trex Residential decking were constrained due to supply issues, which were primarily caused by new product startup inefficiencies late in 2018, through the first quarter of 2019, and to a much lesser extent in the second quarter of 2019 related to our new Enhance product. These supply issues resulted in lower throughput and finished goods inventory than was needed to support market demand. Trex Residential net sales were positively impacted by strength in the residential remodeling sector, our marketing programs at Trex Residential aimed at taking market share from wood and the healthy demand across our full suite of outdoor living products. The increase in total net sales was offset by a 19.2% decrease in Trex Commercial net sales primarily due to reduced volume.

Gross profit as a percentage of net sales, gross margin, was 39.6% in the 2019
six-month
period compared to 44.4% in the 2018
six-month
period. Gross margin for Trex Residential and Trex Commercial products in the 2019
six-month
period totaled 41.0% and 21.0%, respectively, compared to 46.7% and 21.3%, respectively, in the 2018
six-month
period. The decrease in gross margin was primarily due to a decrease in Trex Residential gross profit related to new product startup costs and manufacturing inefficiencies associated with the slower than normal production ramp up on those products, including reduced line rates, increased material usage and lower manufacturing yields. During March and through the second quarter, we made a number of changes to improve throughput. As a result, our production rates returned to planned levels and associated operating inefficiencies have been reduced. Additionally, our Trex Residential Nevada facility had two equipment failures during the first quarter which resulted in the loss of two lines for approximately 30 days each. Those lines are now back in full production.

The $3.4 million increase in selling, general and administrative expenses in the 2019
six-month
period compared to the 2018
six-month
period resulted primarily from an increase of $2.4 million increase in branding and advertising spend in support of our market growth programs, $1.5 million in personnel related expenses, primarily related to executive severance benefits, and $1.4 million in research and development expenses. The increases were offset by a $2.3 million decrease in amortization expense due to the full amortization of intangible assets acquired as part of the SC Company acquisition in July 2017.

LIQUIDITY AND CAPITAL RESOURCES
We finance operations and growth primarily with cash flows from operations, borrowings under our revolving credit facility, operating leases and normal trade credit terms from operating activities. At June 30, 2019 we had $106.1 million of cash and cash equivalents.
S
ources and Uses of Cash.
The following table summarizes our cash flows from operating, investing and financing activities (in thousands):

|  | Six Months Ended June 30, |
|  | 2019 |  |  | 2018 |
Net cash provided by (used in) operating activities |  | $ | 43,058 |  |  | $ | (1,674 | )
Net cash used in investing activities |  |  | (19,061 | ) |  |  | (17,614 | )

Net increase (decrease) in cash and cash equivalents |  | $ | 385 |  |  | $ | (27,613 | )

Operating Activities
Cash provided from operations was $43.1 million during the 2019
six-month
period compared to cash used in operations of $1.7 million during the 2018
six-month
period. The improved cash flows from operations was primarily due to lower working capital investment in accounts receivable and inventory. The reduced investment in inventory resulted from demand for Trex Residential outdoor living products and supply constraints caused primarily by new product startup inefficiencies. The reduced investment in accounts receivables was primarily driven by earlier collections in 2019 as compared to 2018 due to the timing of residential sales within the period. Cash provided from operations during the 2019
six-month
period was offset by increased cash paid for accounts payable and accrued expenses and other liabilities. Cash from operations decreased $1.7 million in the 2018
six-month
period, primarily due to a $104.3 million increase in accounts receivables on $377.9 million in net sales, primarily offset by $80.0 million in net income, a $14.9 million increase in accounts payable and a $3.8 million increase in income taxes payable.

Investing Activities
Capital expenditures in the 2019
six-month
period were $19.1 million, consisting primarily of $15.7 million for general plant cost reduction initiatives and other production improvements and $3.2 million for other
non-production
and general support initiatives. Capital expenditures in the 2018
six-month
period were $11.4 million, consisting primarily of $8.4 million for general plant cost reduction initiatives and other production improvements. During the 2018
six-month
period, we purchased domain names for $6.3 million.
Financing Activities
Net cash used in financing activities was $23.6 million in the 2019
six-month
period primarily for repurchases of our common stock of $24.2 million. Net cash used in financing activities in the 2018
six-month
period was $8.3 million primarily related to $17.2 million for repurchases of our common stock, offset by net borrowings under our line of credit of $8.5 million.
Stock Repurchase Programs.
On February 16, 2018, the Board of Directors adopted a stock repurchase program of up to 5.8 million shares of the Company’s outstanding common stock (Stock Repurchase Program). As of the June 30, 2019, the Company had repurchased 709,461 shares of the Company’s outstanding common stock under the Stock Repurchase Program.
Indebtedness.
Our Third Amended and Restated Credit Agreement, as amended, provides us with revolving loan capacity in a collective maximum principal amount of $250 million from January 1 through June 30 of each year, and a maximum principal amount of $200 million from July 1 through December 31 of each year throughout the term, which ends January 12, 2021. At June 30, 2019, we had no outstanding indebtedness under the revolving credit facility and borrowing capacity under the facility of $250 million.
Debt Covenants.
To remain in compliance with covenants contained within our debt agreements, we must maintain specified financial ratios based on levels of debt, fixed charges, and earnings (excluding extraordinary gains and extraordinary
non-cash
losses) before interest, taxes, depreciation and amortization. At June 30, 2019, we were in compliance with these covenants. Failure to comply with our loan covenants might cause our lenders to accelerate our repayment obligations under our credit facility, which may be declared payable immediately based on a default.
We believe that cash on hand, cash from operations and borrowings expected to be available under our revolving credit facility will provide sufficient funds to fund planned capital expenditures, make scheduled principal and interest payments, fund warranty payments, and meet other cash requirements. We currently expect to fund future capital expenditures from operations and financing activities. The actual amount and timing of future capital requirements may differ materially from our estimate depending on the demand for Trex products and new market developments and opportunities.
Capital Requirements.
In June 2019 we announced a new capital expenditure program to increase production capacity at our Trex Residential facilities in Winchester, Virginia, and Fernley, Nevada. The new multi-year capital expenditure program is projected at approximately $200 million between now and 2021, and involves the construction of a new decking facility at the existing Virginia site and the installation of additional production lines at the Nevada site. It is anticipated that the additional production lines in Nevada will come online beginning in the third quarter of 2019. Additional lines will also be installed by the end of the second quarter of 2020. The Virginia capacity will begin to come online in the first quarter of 2021. The investment will allow us to increase production output for future projected growth related to our strategy of converting wood demand to Trex Residential composite decking. When completed these investments will increase our capacity by approximately 70 percent. As a result of the new capital expenditure program, we have revised our capital expenditure guidance to $75 million - $80 million in 2019. In addition to the above, our capital allocation priorities include expenditures for internal growth opportunities, manufacturing cost reductions, upgrading equipment, and acquisitions which fit out long-term growth strategy as we continue to evaluate opportunities that would be a good strategic fit for Trex, and return of capital to shareholders.
Inventory in Distribution Channels.
We sell our Trex Residential decking and railing products through a tiered distribution system. We have over 50 distributors worldwide and two national retail merchandisers to which we sell our products. The distributors in turn sell the products to dealers and retail locations who in turn sell the products to end users. Significant increases in inventory levels in the distribution channel without a corresponding change in
end-use
demand could have an adverse effect on future sales. We cannot definitively determine the level of inventory in the distribution channels at any time. We are not aware of any significant increases in the levels of inventory in the distribution channels at June 30, 2019 compared to inventory levels at June 30, 2018.

Seasonality
. The operating results for Trex Residential have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex Residential has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs. The operating results for Trex Commercial have not historically varied from quarter to quarter as a result of seasonality. However, they are driven by the timing of individual projects, which may vary each quarterly period.

(collectively, the standard). The standard requires lessees to recognize operating leases on the balance sheet as a
right-of-use
asset and a lease liability. The liability is equal to the present value of the lease payments over the remaining lease term. The asset is based on the liability, subject to certain adjustments. Operating leases result in straight-line expense. The Company adopted the standard on January 1, 2019, and elected the transition method of adoption, which allowed the Company to apply the standard as of the beginning of the period of adoption. The Company opted to elect the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs, and certain other practical expedients, including the use of hindsight to determine the lease term for existing leases and in assessing impairment of the
right-of-use
asset, and the exception for short-term leases. For its current classes of underlying assets, the Company did not elect the practical expedient under which the lease components would not be separated from the nonlease components. Nonlease components include certain maintenance services provided by the lessor and the related consideration is specified on a stand-alone basis in the applicable lease agreements. Adoption of the standard had a significant impact on the Company’s condensed consolidated balance sheet due to the recognition of a
right-of-use
asset and lease liability of $45.8 million and $47.2 million, respectively, upon adoption. As the Company’s leases do not provide an implicit rate that can be readily determined, the Company used its incremental borrowing rate based on the information available at the implementation date in determining the present value of lease payments.
