Organization and Summary of Significant Accounting Policies

Description of Business

As of December 31, 2018, Pool Corporation and our subsidiaries (the Company, which may be referred to as we, us or our), operated 364 sales centers in North America, Europe, South America and Australia from which we sell swimming pool supplies, equipment and related leisure products, irrigation and landscape products, and hardscape, tile and stone products to pool builders, retail stores, service companies, landscape contractors and golf courses. We distribute products through four networks: SCP Distributors (SCP), Superior Pool Products (Superior), Horizon Distributors (Horizon) and National Pool Tile (NPT).

Basis of Presentation and Principles of Consolidation

We prepared the Consolidated Financial Statements following U.S. generally accepted accounting principles (GAAP) and the requirements of the Securities and Exchange Commission (SEC). The financial statements include all normal and recurring adjustments that are necessary for a fair presentation of our financial position and operating results. The Consolidated Financial Statements include the accounts of Pool Corporation and our subsidiaries. All significant intercompany accounts and intercompany transactions have been eliminated.

All of our subsidiaries are wholly owned. From July 31, 2014 to June 29, 2017, we owned a 60% interest in Pool Systems Pty. Ltd. (PSL), an Australian company. Our ownership percentage constituted a controlling interest in the acquired company, which required us to consolidate PSL’s financial position and results of operations from the date of acquisition. On June 29, 2017, we purchased the remaining 40% interest in PSL. Thus, we have continued to consolidate PSL, but there is no longer a separate noncontrolling interest reported on our Consolidated Statements of Income, nor Redeemable noncontrolling interest reported on our Consolidated Balance Sheets.

Variable Interest Entity

In February 2015, we entered into a five-year credit agreement with a swimming pool retailer. Under this agreement and the related revolving note, we were the primary lender of operating funds for this entity. The total lending commitment under the credit agreement was $8.5 million. In December 2017, we ended our lending arrangement with this entity and exercised our rights to the collateral that secured this agreement. The collateral was sufficient to satisfy the net balance previously recorded within Other assets on our Consolidated Balance Sheets.

Use of Estimates

To prepare financial statements that conform to GAAP, we make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Our most significant estimates relate to the allowance for doubtful accounts, inventory obsolescence reserves, vendor programs, income taxes, performance-based compensation accruals and goodwill impairment evaluations. We continually review our estimates and make adjustments as necessary, but actual results could be significantly different from what we expected when we made these estimates.

Newly Adopted Accounting Pronouncements

On January 1, 2018, we adopted Accounting Standards Update (ASU) 2014-09, Revenue - Revenue from Contracts with Customers, and all the related amendments, which are also codified into Accounting Standards Codification (ASC) 606. We elected to adopt this guidance using the modified retrospective method. The adoption of this standard did not have a material impact on our financial position or results of operations. We did not restate prior period information for the effects of the new standard, nor did we adjust the opening balance of our retained deficit to account for the implementation of the new requirements of this standard. We do not expect the adoption of this guidance to have a material effect on our results of operations in future periods. See Revenue Recognition within this note for additional information.

On January 1, 2018, we adopted ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The new guidance specifies how cash flows should be classified for debt prepayment or extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds for the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance, distributions from equity method investees and beneficial interests in securitization transactions. Our adoption of ASU 2016-15 had no impact on our Consolidated Statement of Cash Flows as our previous classifications related to contingent consideration payments and distributions from equity method investees is consistent with the requirements of ASU 2016-15.

On January 1, 2017, we adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, on a prospective basis. The provisions of this update simplify many key aspects of the accounting for and cash flow presentation of employee share-based compensation transactions, including accounting for income taxes, forfeitures, and statutory withholding requirements. In accordance with the new guidance, we now record all excess tax benefits or tax deficiencies as a component of our Provision for income taxes on our Consolidated Statements of Income. Historically, these amounts were recorded as Additional paid in capital in stockholders’ equity on our Consolidated Balance Sheets. Additionally, we now present excess tax benefits or deficiencies as operating cash flows versus reclassifying the amount out of operating cash flows and presenting it as a financing activity on the Consolidated Statements of Cash Flows. See Income Taxes within this note for additional information.

On December 31, 2016, we adopted ASU 2014-15, Presentation of Financial Statements - Going Concern. Based on management’s evaluation, which included forecasting results covering the one-year period following our 2018 Form 10-K filing date, we did not identify any conditions or events that raise substantial doubt about our ability to continue as a going concern.

Segment Reporting

Since all of our sales centers have similar operations and share similar economic characteristics, we aggregate our sales centers into a single reportable segment. These similarities include (i) the nature of our products and services, (ii) the types of customers we sell to and (iii) the distribution methods we use. Our chief operating decision maker (CODM) evaluates each sales center based on individual performance that includes both financial and operational measures. These measures include operating income growth and accounts receivable and inventory management criteria. Each sales center manager and eligible field employee earns performance‑based incentive compensation based on these measures developed at the sales center level.

A bottom-up approach is used to develop the operating budget for each individual sales center. The CODM approves the budget and routinely monitors budget to actual results for each sales center. Additionally, our CODM makes resource allocation decisions primarily on a sales center-by-sales center basis. No single sales center meets any of the quantitative thresholds (10% of revenues, profit or assets) for separately reporting information about an operating segment. We do not track sales by product lines and product categories on a consolidated basis. We lack readily available financial information due to the number of our product lines and product categories and the fact that we make ongoing changes to product classifications within these groups, thus making it impracticable to report our sales by product category.

Seasonality and Weather

Our business is highly seasonal and weather is one of the principal external factors affecting our business. In general, sales and net income are highest during the second and third quarters, which represent the peak months of both swimming pool use and installation and irrigation and landscape installations and maintenance. Sales are substantially lower during the first and fourth quarters, when we may incur net losses.

Revenue Recognition

Under ASC 606, we recognize a sale when a customer obtains control of the product, and we record the amount that reflects the consideration we expect to receive in exchange for such product. As under the previous accounting guidance, we continue to recognize a sale when a customer picks up product at any sales center, when we deliver product to their premises or job sites via our trucks or when we present the product to a third-party carrier. For bill and hold sales, we determine when the customer obtains control of the product on a case-by-case basis to determine the amount of revenue to recognize each period.

Our adoption of ASC 606 resulted in balance sheet reclassifications for recording our estimate of customer returns. ASC 606 requires the recognition of a current liability for the gross amount of estimated returns and a current asset for the cost of the related products. This change did not have a material impact on our Consolidated Balance Sheet as of December 31, 2018.

We consider our distribution of products to represent one reportable revenue stream. Our products are similar in nature, and our revenue recognition policy is the same across our distribution networks. Our customers share similar characteristics and purchase products across all categories. We recognize revenue when our customers take control of our products. For customer pick-ups or deliveries by our trucks, control passes when our customers receive our products. For third-party deliveries, control passes when we present our products to the third-party carriers. We include shipping and handling fees billed to customers as freight out income within net sales.

We measure revenue as the amount of consideration we expect to receive in exchange for transferring our products. Consideration may vary due to volume incentives and expected customer returns. We offer volume incentives to some of our customers and account for these incentives as a reduction of sales. We estimate the amount of volume incentives earned based on our estimate of cumulative sales for the fiscal year relative to our customers’ progress toward achieving minimum purchase requirements. We record customer returns, including those associated with customer early buy programs, as a reduction of sales. Based on available information related to our customers’ returns, we record an allowance for estimated returns, which historically has not been material. We regularly review our marketing programs, coupons and customary business practices to determine if any variable consideration exists under ASC 606. Other items that we record as reductions to sales include cash discounts, pricing adjustments and credit card fees related to customer payments.

The majority of our sales transactions do not contain additional performance obligations after delivery; therefore, we do not have multiple performance obligations for which to allocate the transaction price. We elected to continue to recognize shipping and handling costs associated with outbound freight in selling and administrative expenses.

We report sales net of tax amounts that we collect from our customers and remit to governmental authorities. These tax amounts may include, but are not limited to, sales, use, value-added and some excise taxes.

Vendor Programs

Many of our arrangements with our vendors provide for us to receive specified amounts of consideration when we achieve any of a number of measures. These measures are generally related to the volume level of purchases from our vendors, or our net cost of products sold, and may include negotiated pricing arrangements. We account for vendor programs as a reduction of the prices of the vendors’ products and as a reduction of inventory until we sell the products, at which time such considerations are recognized as a reduction of Cost of sales on our Consolidated Statements of Income.

Throughout the year, we estimate the amount earned based on our expectation of total purchases for the fiscal year relative to the purchase levels that mark our progress toward earning each program. We accrue vendor benefits on a monthly basis using these estimates, provided that we determine they are probable and reasonably estimable. We continually revise these estimates to reflect actual credits earned based on actual purchase levels and trends related to sales and purchasing mix. When we make adjustments to our estimates, we determine whether any portion of the adjustment impacts the amount of vendor credits that are deferred in inventory. We recognize changes in our estimates as a cumulative catch-up adjustment to the amounts recognized to date in our Consolidated Financial Statements.

Shipping and Handling Costs

We record shipping and handling costs associated with inbound freight as cost of sales. The table below presents shipping and handling costs associated with outbound freight, which we include in selling and administrative expenses (in thousands):



2018		2017		2016
$	48,610	$	45,247	$	39,879

Share-Based Compensation

We record share-based compensation for stock options and other share-based awards based on the estimated fair value as measured on the grant date. For stock option awards, we use a Black-Scholes model for estimating the grant date fair value. For additional discussion of share‑based compensation, see Note 6.

Advertising Costs

We expense advertising costs when incurred. The table below presents advertising expense for the past three years (in thousands):



2018		2017		2016
$	7,390	$	7,477	$	7,011

Income Taxes

Both the Tax Cuts and Jobs Act (the Act), enacted by Congress in December 2017, and ASU 2016-09, which we adopted on January 1, 2017, impacted our provision for income taxes by substantially reducing our income tax rate in 2018 and 2017.

As of December 31, 2018, we have resolved our contingent accounting related to the tax effects of the Act. We filed our federal income tax return in the third quarter of 2018, and our return to provision adjustment, which addresses the provisional tax benefit we recorded under Staff Accounting Bulletin (SAB) 118 at December 31, 2017, was not material. We have considered the impact of the statutory changes from the Act on our estimated effective tax rate for 2018, including reasonable estimates of those provisions effective for the 2018 tax year. The Act also created a new requirement that certain income earned by foreign subsidiaries, global intangible low-taxed income (GILTI), be included in the gross income of their U.S. shareholder. Entities may make an accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or recognize such taxes as a current-period expense when incurred. We elected to treat the tax effect of GILTI as a current-period expense when incurred.

We reduce federal and state income taxes payable by the tax benefits associated with the exercise of nonqualified stock options and the lapse of restrictions on restricted stock awards. To the extent realized tax deductions exceed the amount of previously recognized deferred tax benefits related to share-based compensation, we record an excess tax benefit. We record all excess tax benefits as a component of income tax benefit or expense in the income statement in the period in which stock options are exercised or restrictions on stock awards lapse.

For additional information regarding income taxes, see Note 7.

Equity Method Investments

We account for our 50% investment in Northpark Corporate Center, LLC (NCC) using the equity method of accounting. Accordingly, we report our share of income or loss based on our ownership interest in this investment.

Earnings Per Share

We calculate basic earnings per share (EPS) by dividing Net income or loss attributable to Pool Corporation by the weighted average number of common shares outstanding. We include outstanding unvested restricted stock awards of our common stock in the basic weighted average share calculation. Diluted EPS reflects the dilutive effects of potentially dilutive securities, which include in‑the‑money outstanding stock options and shares to be purchased under our employee stock purchase plan. Using the treasury stock method, the effect of dilutive securities includes these additional shares of common stock that would have been outstanding based on the assumption that these potentially dilutive securities had been issued. For additional discussion of earnings per share, see Note 8.

Foreign Currency

The functional currency of each of our foreign subsidiaries is its applicable local currency. We translate our foreign subsidiary financial statements into U.S. dollars based on published exchange rates. We include these translation adjustments as a component of Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. We include realized transaction gains and losses that arise from exchange rate fluctuations in Interest and other non-operating expenses, net on the Consolidated Statements of Income. We realized net foreign currency transaction losses of $0.6 million in 2018, gains of $0.2 million in 2017 and losses of $0.7 million in 2016.

Fair Value Measurements

Our assets and liabilities that are measured at fair value on a recurring basis include the unrealized gains or losses on our interest rate swap contracts and contingent consideration related to recent acquisitions. The three levels of the fair value hierarchy under the accounting guidance are described below:


Level 1	Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.


Level 2	Inputs to the valuation methodology include:


•	quoted prices for similar assets or liabilities in active markets;


•	quoted prices for identical or similar assets or liabilities in inactive markets;


•	inputs other than quoted prices that are observable for the asset or liability; or


•	inputs that are derived principally from or corroborated by observable market data by correlation or other means.


Level 3	Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The table below presents the estimated fair values of our interest rate swap contracts, our forward-starting interest rate swap contract and our contingent consideration liabilities (in thousands):



	Fair Value at December 31,
	2018		2017
Level 2
Unrealized gains on interest rate swaps	$	2,378	$	1,585
Unrealized losses on interest rate swaps	—		703

Level 3
Contingent consideration liabilities	$	1,117	$	1,824

We include unrealized gains in Prepaid expenses and other current assets and unrealized losses in Accrued expenses and other current liabilities on the Consolidated Balance Sheets. As of December 31, 2018, our Consolidated Balance Sheets reflect $0.3 million in Accrued expenses and other current liabilities and $0.8 million in Other long-term liabilities related to our estimates for contingent consideration payouts.

The carrying values of cash, receivables, accounts payable and accrued liabilities approximate fair value due to the short maturity of those instruments (Level 1 inputs).

For determining the fair value of our interest rate swap and forward-starting interest rate swap contracts, we use significant other observable market data or assumptions (Level 2 inputs as defined in the accounting guidance) that we believe market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. Our fair value estimates reflect an income approach based on the terms of the interest rate swap contracts and inputs corroborated by observable market data including interest rate curves.

The carrying value of long-term debt approximates fair value (Level 3 inputs). Our determination of the estimated fair value reflects a discounted cash flow model using our estimates, including assumptions related to borrowing rates (Level 3 inputs).

Derivatives and Hedging Activities

If determined to be effective cash flow hedges, we record the changes in the estimated fair value of our interest rate swap contracts to Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. To the extent our interest rate swaps are determined to be ineffective, we recognize the changes in the estimated fair value in Interest and other non-operating expenses, net on our Consolidated Statements of Income. We assess hedge effectiveness on a quarterly basis.

Our interest rate swap and forward-starting interest rate swap contracts are subject to master netting arrangements. According to our accounting policy, we do not offset the fair values of assets with the fair values of liabilities related to these contracts.

We recognize any differences between the variable interest rate payments and the fixed interest rate settlements from our swap counterparties as an adjustment to interest expense over the life of the swaps.

For our interest rate swap contracts currently in effect, a portion of the change in the estimated fair value between periods relates to future interest expense. Recognition of the change in fair value between periods attributable to accrued interest is reclassified from Accumulated other comprehensive income (loss) to Interest and other non-operating expenses, net on the Consolidated Statements of Income. These amounts were not material in any period presented. For additional discussion of our interest rate swaps, see Note 5.

Cash Equivalents

We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Credit Risk and Allowance for Doubtful Accounts

We record trade receivables at the invoiced amounts less an allowance for doubtful accounts for estimated losses we may incur if customers do not pay. We perform periodic credit evaluations of our customers and we typically do not require collateral. Consistent with industry practices, we generally require payment from our North American customers within 30 days, except for sales under early buy programs for which we provide extended payment terms to qualified customers.

At the end of each quarter, we perform a reserve analysis of all accounts with balances greater than $20,000 and more than 60 days past due. Additionally, we perform a separate reserve analysis on the balance of our accounts receivables with emphasis on the remainder of the past due portion of the aging. During the year, we write off account balances when we have exhausted reasonable collection efforts and determined that the likelihood of collection is remote. These write-offs are charged against our allowance for doubtful accounts.

The following table summarizes the changes in our allowance for doubtful accounts for the past three years (in thousands):



	2018			2017			2016
Balance at beginning of year	$	3,897		$	4,050		$	4,205
Bad debt expense	4,164			916			1,199
Write-offs, net of recoveries	(1,879		)	(1,069		)	(1,354		)
Balance at end of year	$	6,182		$	3,897		$	4,050

Product Inventories and Reserve for Inventory Obsolescence

Product inventories consist primarily of goods we purchase from manufacturers to sell to our customers. We record inventory at the lower of cost, using the average cost method, or net realizable value. We establish our reserve for inventory obsolescence based on inventory turns by class with particular emphasis on stock keeping units with the weakest sales over the expected sellable period, which is the previous 12 months for most products. The reserve is intended to reflect the net realizable value of inventory that we may not be able to sell at a profit.

In evaluating the adequacy of our reserve for inventory obsolescence, we consider a combination of factors including:


•	the level of inventory in relation to historical sales by product, including inventory usage by class based on product sales at both the sales center and on a company-wide basis;


•	changes in customer preferences or regulatory requirements;


•	seasonal fluctuations in inventory levels;


•	geographic location; and


•	superseded products and new product offerings.

We periodically adjust our reserve for inventory obsolescence as changes occur in the above-identified factors.

The following table summarizes the changes in our reserve for inventory obsolescence for the past three years (in thousands):



	2018			2017			2016
Balance at beginning of year	$	6,264		$	6,531		$	6,979
Provision for inventory write-downs	3,998			2,660			2,036
Deduction for inventory write-offs	(2,536		)	(2,927		)	(2,484		)
Balance at end of year	$	7,726		$	6,264		$	6,531

Property and Equipment

Property and equipment are stated at cost. We depreciate property and equipment on a straight-line basis over the following estimated useful lives:



Buildings	40 years
Leasehold improvements ⁽¹⁾	1 - 10 years
Autos and trucks	3 - 6 years
Machinery and equipment	3 - 15 years
Computer equipment	3 - 7 years
Furniture and fixtures	5 - 10 years


⁽¹⁾	For substantial improvements made near the end of a lease term where we are reasonably certain the lease will be renewed, we amortize the leasehold improvement over the remaining life of the lease including the expected renewal period.

The table below presents depreciation expense for the past three years (in thousands):



2018		2017		2016
$	26,122	$	24,157	$	20,338

Acquisitions

We use the acquisition method of accounting and recognize assets acquired and liabilities assumed at fair value as of the acquisition date. Any contingent assets acquired and contingent liabilities assumed are also recognized at fair value if we can reasonably estimate fair value during the measurement period (which cannot exceed one year from the acquisition date). We re-measure any contingent liabilities at fair value in each subsequent reporting period. We expense all acquisition-related costs as incurred, including any restructuring costs associated with a business combination.

If our initial acquisition accounting is incomplete by the end of the reporting period in which a business combination occurs, we report provisional amounts for incomplete items. Once we obtain information required to finalize the accounting for incomplete items, we adjust the provisional amounts recognized. We make adjustments to these provisional amounts during the measurement period.

For all acquisitions, we include the results of operations in our Consolidated Financial Statements as of the acquisition date. For additional discussion of acquisitions, see Note 2.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the amount we paid to acquire a company over the estimated fair value of tangible assets and identifiable intangible assets acquired, less liabilities assumed. We test goodwill and other indefinite-lived intangible assets for impairment annually as of October 1st and at any other time when impairment indicators exist.

We estimate fair value based on an income approach that incorporates our assumptions for determining the present value of future cash flows. We project future cash flows using management’s assumptions for sales growth rates, operating margins, discount rates and multiples. These assumptions are considered unobservable inputs (Level 3 inputs as defined in the accounting guidance). If the estimated fair value of any of our reporting units falls below its carrying value, we compare the estimated fair value of the reporting unit’s goodwill to its carrying value. If the carrying value of a reporting unit’s goodwill exceeds its estimated fair value, we perform a calculation to measure impairment, which includes valuing the tangible and intangible assets. We recognize any impairment loss in operating income. Since we define an operating segment as an individual sales center and we do not have operations below the sales center level, our reporting unit is an individual sales center. For additional discussion of goodwill and other intangible assets, see Note 3.

Receivables Securitization Facility

Our accounts receivable securitization facility (the Receivables Facility) provides for the sale of certain of our receivables to a wholly owned subsidiary (the Securitization Subsidiary). The Securitization Subsidiary transfers variable undivided percentage interests in the receivables and related rights to certain third-party financial institutions in exchange for cash proceeds, limited to the applicable funding capacities.

We account for the sale of the receivable interests as a secured borrowing on our Consolidated Balance Sheets. The receivables subject to the agreement collateralize the cash proceeds received from the third-party financial institutions. We classify the entire outstanding balance as Long-term debt on our Consolidated Balance Sheets as we intend and have the ability to refinance the obligations on a long‑term basis. We present the receivables that collateralize the cash proceeds separately as Receivables pledged under receivables facility on our Consolidated Balance Sheets. For additional discussion of the Receivables Facility, see Note 5.

Self-Insurance

We are self-insured for employee health benefits, workers’ compensation coverage, property and casualty, and automobile insurance. To limit our exposure, we also maintain excess and aggregate liability coverage. We establish self‑insurance reserves based on estimates of claims incurred but not reported and information that we obtain from third-party service providers regarding known claims. Our management reviews these reserves based on consideration of various factors, including but not limited to the age of existing claims, estimated settlement amounts and other historical claims data.

Redeemable Noncontrolling Interest

In July 2014, we purchased a controlling interest in PSL. Included in the transaction documents was a put/call option deed that granted us an option to purchase the shares held by the noncontrolling interest and granted the holder of the noncontrolling interest an option to require us to purchase its shares in one or two transactions. In applying the guidance for this transaction, we determined that the financial instrument was embedded in the noncontrolling interest. As a public company, we were required to classify the noncontrolling interest and the embedded financial instrument as redeemable noncontrolling interest in a separate section of our Consolidated Balance Sheets, between liabilities and equity.

On June 29, 2017, we purchased the remaining 40% interest in PSL. The actual redemption value exceeded the carrying amount, and we recorded an adjustment to Additional paid in capital as there were no retained earnings attributable to the noncontrolling interest.

The table below presents the changes in Redeemable noncontrolling interest (in thousands):



	2018		2017			2016
Redeemable noncontrolling interest, beginning of period	$	—	$	2,287		$	2,665
Redemption value adjustment of noncontrolling interest	—		360			—
Net loss attributable to noncontrolling interest	—		(294		)	(352		)
Other comprehensive income (loss) attributable to noncontrolling interest	—		220			(26		)
Less: purchase of redeemable noncontrolling interest	—		2,573			—
Redeemable noncontrolling interest, end of period	$	—	$	—		$	2,287

Accumulated Other Comprehensive Loss

The table below presents the components of our Accumulated other comprehensive loss balance (in thousands):



	December 31,
	2018			2017
Foreign currency translation adjustments	$	(12,422	)	$	(7,478	)
Unrealized gains on interest rate swaps, net of tax ⁽¹⁾	1,425			150
Accumulated other comprehensive loss	$	(10,997	)	$	(7,328	)

⁽¹⁾

In February 2018, the Financial Accounting Standards Board (FASB) issued guidance that allows entities the option to reclassify the tax effects related to items in accumulated other comprehensive income (loss) to retained earnings (deficit) if deemed to be stranded in accumulated other comprehensive income (loss) due to U.S. tax reform. We do not have any material amounts stranded in Accumulated other comprehensive loss from U.S. tax reform.

Retained Deficit

We account for the retirement of treasury share repurchases as an increase of our Retained deficit on our Consolidated Balance Sheets. As of December 31, 2018, the retained deficit reflects cumulative net income, the cumulative impact of adjustments for changes in accounting pronouncements, treasury share retirements since the inception of our share repurchase programs of $1,426.8 million and cumulative dividends of $495.1 million.

Supplemental Cash Flow Information

The following table presents supplemental disclosures to the accompanying Consolidated Statements of Cash Flows (in thousands):



	Year Ended December 31,
	2018		2017		2016
Cash paid during the year for:
Interest	$	17,796	$	12,957	$	8,052
Income taxes, net of refunds	50,091		84,251		80,378

Recent Accounting Pronouncements Pending Adoption

The following table summarizes the remaining recent accounting pronouncements that we plan to adopt in future periods:



Standard	Description	Effective Date	Effect on Financial Statements and Other Significant Matters
ASU 2016-02, Leases (Topic 842)	Requires lessees to record most leases on their balance sheets but recognize expenses in a manner similar to current guidance. The guidance is required to be applied using a modified retrospective approach.	Annual periods beginning after December 15, 2018	The adoption of ASU 2016-02 will significantly increase assets and liabilities on our consolidated balance sheets. We are finalizing our testing of the information gathered to properly account for the new standard. Based on our current lease portfolio, assumptions related to borrowing rates, and conclusions related to renewal periods, we expect to record a right-of-use asset and corresponding liability for each of our existing operating leases of approximately $180.0 million. We do not expect a material impact on our results of operations and cash flows. Upon adoption, we expect to apply the package of practical expedients available within the new standard, which is intended to provide some relief to issuers. We will also have expanded disclosures upon adoption.
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities	Eliminates the requirement to separately measure and report hedge ineffectiveness. For qualifying cash flow and net investment hedges, the change in the fair value of the hedging instrument will be recorded in Other Comprehensive Income (OCI), and amounts deferred in OCI will be reclassified to earnings in the same income statement line item that is used to present the earnings effect of the hedged item.	Annual periods beginning after December 15, 2018	We do not expect this accounting pronouncement will have a material impact on our financial position, results of operations and related disclosures.



Standard	Description	Effective Date	Effect on Financial Statements and Other Significant Matters
ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	Changes the way companies evaluate credit losses for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model to evaluate impairment, potentially resulting in earlier recognition of allowances for losses. The new standard also requires enhanced disclosures, including the requirement to disclose the information used to track credit quality by year of origination for most financing receivables. The guidance must be applied using a cumulative-effect transition method.	Annual periods beginning after December 15, 2019	We are currently evaluating the effect this will have on our financial position, results of operations and related disclosures.
ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	Eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (commonly referred to as Step 2 under the current guidance). Rather, the measurement of a goodwill impairment charge will be based on the excess of a reporting unit’s carrying value over its fair value (Step 1 under the current guidance). This guidance should be applied prospectively.	Annual and interim impairment tests performed in periods beginning after December 15, 2019	We are currently evaluating the effect this will have on our financial position, results of operations and related disclosures.
