Organization and Summary of Significant Accounting Policies

Description of Business

As of December 31, 2015, Pool Corporation and our subsidiaries (the Company, which may be referred to as we, us or our), operated 336 sales centers in North America, Europe, South America and Australia from which we sell swimming pool equipment, parts and supplies, 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 with the exception of Pool Systems Pty. Ltd. (PSL), an Australian company. On July 31, 2014, we completed the purchase of a 60% interest in PSL and accounted for this acquisition using the acquisition method of accounting. The purchase constitutes a controlling interest in the acquired company, which requires us to consolidate PSL’s financial position and results of operations from the date of acquisition.

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 are the primary lender of operating funds for this entity. The total lending commitment under the credit agreement is $8.5 million, of which $6.2 million is owed as of December 31, 2015. Amounts funded under the credit agreement are recorded within Other assets, net on our Consolidated Balance Sheets and are collateralized by essentially all of the assets of the business. We have a variable interest in this entity; however, we have no decision-making authority over its activities through voting or other rights. Additionally, we have no obligation to absorb any of its losses, nor do we have the right to receive any residual returns, should either occur. We are not considered the primary beneficiary of this variable interest entity, and therefore we are not required to consolidate this entity’s financial statements.

Use of Estimates

In order 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 are those relating to the allowance for doubtful accounts, inventory obsolescence reserves, vendor incentives, income taxes, incentive 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.

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 decisions about how to allocate resources 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 as to how products are classified 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 landscape installations and maintenance. Sales are substantially lower during the first and fourth quarters, when we may incur net losses.

Revenue Recognition

We recognize revenue when four basic criteria are met:

1. persuasive evidence of an arrangement exists;

2. delivery has occurred or services have been rendered;

3. our price to the buyer is fixed or determinable; and

4. collectibility is reasonably assured.

We record revenue when customers take delivery of products. Customers may pick up products at any sales center location, or we may deliver products to their premises or job sites via our trucks or third party carriers. Products shipped via third party carriers are considered delivered based on the shipping terms, which are generally FOB shipping point. We include shipping and handling fees billed to customers as freight out income within net sales.

We offer volume incentives to some of our customers and we account for these incentives as an adjustment to 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 early buy programs, as an adjustment to sales. Historically customer returns have not been material. Other items that we record as adjustments to sales include cash discounts, pricing adjustments and credit card fees related to customer payments.

We also 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 Incentives

Many of our arrangements with our vendors provide for us to receive incentives of 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 and may include negotiated pricing arrangements. We account for vendor incentives as a reduction of the prices of the vendors’ products and therefore as a reduction of inventory until we sell the products, at which time such incentives are recognized as a reduction of Cost of sales on our Consolidated Statements of Income.

Throughout the year, we estimate the amount of the incentives earned based on our estimate of total purchases for the fiscal year relative to the purchase levels that mark our progress toward earning the incentives. We accrue vendor incentives 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 incentives 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 incentives that are deferred in inventory. We recognize changes in our estimates for vendor incentives 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):



2015		2014		2013
$	36,783	$	38,674	$	35,010

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):



2015		2014		2013
$	7,127	$	6,894	$	5,917

Income Taxes

We record deferred tax assets and liabilities based on differences between the financial reporting and tax basis of assets and liabilities using currently enacted rates and laws that will be in effect when we expect the differences to reverse. Due to changing tax laws and state income tax rates, significant judgment is required to estimate the effective tax rate expected to apply to tax differences that are expected to reverse in the future.

We record a valuation allowance to reduce the carrying amounts of net deferred tax assets if there is uncertainty regarding their future realization. We consider many factors when assessing the likelihood of future realization including our recent cumulative earnings experience by taxing jurisdiction, expectations of future taxable income, the carryforward periods available to us for tax reporting purposes and other relevant factors. For additional discussion of 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 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 earnings per share includes the dilutive effects of other share-based awards. 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 $0.8 million in 2015, $0.3 million in 2014 and $0.2 million in 2013.

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 contracts and our contingent consideration liabilities (in thousands):



	Fair Value at December 31,
	2015			2014
Level 2
Unrealized losses on interest rate swaps	$	(3,295	)	$	(2,207	)

Level 3
Contingent consideration	$	(806	)	$	(165	)

We include unrealized losses in Accrued expenses and other current liabilities on the Consolidated Balance Sheets. 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.

As of December 31, 2015, our Consolidated Balance Sheets reflect $0.2 million in Accrued expenses and other current liabilities and $0.6 million in Other long-term liabilities for contingent consideration related to future payouts for our acquisition of The Melton Corporation. In determining the estimate for contingent consideration, which is based on a percentage of gross profit for certain products, we applied a linear model using our best estimate of gross profit projections for fiscal years 2016 to 2020 (Level 3 inputs as defined in the accounting guidance). We have made no adjustments to our estimates since the acquisition date. Any adjustments to the fair value of contingent consideration would be recognized in earnings in the period in which we determined that the fair value changed. Based on our gross profit projections for The Melton Corporation as of December 31, 2015, we determined that the contingent consideration liability was in a range of acceptable estimates as of December 31, 2015.

As of December 31, 2014, our Consolidated Balance Sheets reflected $0.2 million in Accrued expenses and other current liabilities for our estimate of a potential future payout for the PSL acquisition. Based on PSL’s earnings for its fiscal 2015, we determined that a payout would no longer be required. We recognized this adjustment to the fair value of contingent consideration in earnings during the second quarter of 2015.

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). The carrying value of the note receivable with our variable interest entity approximates fair value. Our determination of the estimated fair value reflects a discounted cash flow model using our estimates, including assumptions related to collectibility (Level 3 inputs). The carrying value of long-term debt approximates fair value. 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

We have designated our interest rate swap and forward-starting interest rate swap contracts as cash flow hedges, and we assess hedge effectiveness on a quarterly basis. To the extent that these hedges are effective, we record the changes in the estimated fair value of the swaps to Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. Any hedge ineffectiveness is recorded as a component of Interest and other non-operating expenses, net on our Consolidated Statements of Income.

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. As of December 31, 2015 and December 31, 2014, each of our interest rate swap and forward-starting interest rate swap contracts was in a liability position.

For our five 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 2015, 2014 or 2013.

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 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):



	2015			2014			2013
Balance at beginning of year	$	4,008		$	4,547		$	5,477
Bad debt expense	1,110			1,167			838
Write-offs, net of recoveries	(913		)	(1,706		)	(1,768		)
Balance at end of year	$	4,205		$	4,008		$	4,547

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 market. 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 previous 12 months (or 36 months for tile and parts 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):



	2015			2014			2013
Balance at beginning of year	$	6,403		$	7,103		$	7,520
Provision for inventory write-downs	3,043			1,535			1,538
Deduction for inventory write-offs	(2,467		)	(2,235		)	(1,955		)
Balance at end of year	$	6,979		$	6,403		$	7,103

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):



2015		2014		2013
$	16,373	$	14,495	$	13,359

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 remeasure 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 retrospectively adjust the provisional amounts recognized as of the acquisition date. 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 recognize the difference as an 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 is a put/call option deed that grants us an option to purchase the shares held by the noncontrolling interest, and grants the holder of the noncontrolling interest an option to require us to purchase its shares in one or two transactions. The put/call option deed in this transaction is considered an equity contract and therefore a financial instrument under the accounting guidance. In applying the guidance for this transaction, we have determined that the financial instrument is embedded in the noncontrolling interest. As a public company, we are 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.

At the end of each period, we record the portion of comprehensive income or loss attributable to the noncontrolling interest to Redeemable noncontrolling interest to determine the carrying amount. We are required to compare the carrying amount to our estimated redemption value at the end of each reporting period. The redemption value is based on a multiple of a PSL earnings measure for a specified time period. To the extent that the estimated redemption value exceeds the carrying amount, we would record an adjustment to Redeemable noncontrolling interest. We did not record such an adjustment in the year ended December 31, 2015.

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



	December 31, 2015
Redeemable noncontrolling interest, beginning of period	$	3,113
Net loss attributable to noncontrolling interest	(51		)
Other comprehensive loss attributable to noncontrolling interest	(397		)
Redeemable noncontrolling interest, end of period	$	2,665

Accumulated Other Comprehensive Loss

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



	December 31,
	2015			2014
Foreign currency translation adjustments	$	(11,362	)	$	(2,316	)
Unrealized losses on interest rate swaps, net of tax	(2,367		)	(1,346		)
Accumulated other comprehensive loss	$	(13,729	)	$	(3,662	)

Retained (Deficit) Earnings

We account for the retirement of treasury share repurchases as a reduction of Retained (deficit) earnings on our Consolidated Balance Sheets. As of December 31, 2015, 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 $914.9 million and cumulative dividends declared of $318.0 million.

Supplemental Cash Flow Information

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