Nature of Business and Significant Accounting Policies | Nature of Business and Significant Accounting Policies Nature of business: SiteOne Landscape Supply, Inc. (hereinafter collectively with all its consolidated subsidiaries referred to as the “Company” or individually as “Holdings”) is a wholesale distributor of irrigation supplies, fertilizer and control products (e.g., herbicides), landscape accessories, nursery goods, hardscapes (including pavers, natural stone, and blocks), outdoor lighting, and ice melt products to green industry professionals. The Company also provides value-added consultative services to complement its product offering and to help customers operate and grow their businesses. Substantially all of the Company’s sales are to customers located in the United States of America (“U.S.”), with less than two percent of sales and less than five percent of total assets in Canada for all periods presented. As of January 3, 2021, the Company had over 570 branches. Based on the nature of the Company’s products and customers’ business cycles, sales are significantly higher in the second and third quarters of each fiscal year. Stock Offering On August 3, 2020, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with BofA Securities, Inc. (the “Underwriter”), relating to an underwritten public offering of 2,150,000 shares of the Company’s common stock, $0.01 par value per share (the “Common Stock”). Under the terms of the Underwriting Agreement, the Company granted the Underwriter an option, exercisable for 30 days, to purchase up to an additional 322,500 shares of Common Stock. The Underwriter did not exercise the option to purchase additional shares of Common Stock. The aggregate proceeds to the Company from the sale of shares of Common Stock in the offering were approximately $262.3 million before expenses of approximately $0.6 million. The offering closed on August 6, 2020. The Company has used a portion of the proceeds and intends to use the remaining net proceeds from the offering for general corporate purposes, which may include the acquisition of companies or businesses, the repayment and refinancing of debt, working capital and capital expenditures. The shares of Common Stock sold in the offering were issued pursuant to an automatically effective shelf registration statement on Form S-3ASR (Registration No. 333-240295) and the related prospectus that was filed with the Securities and Exchange Commission (“SEC”) on August 3, 2020, and a related prospectus supplement, dated August 3, 2020. COVID-19 Pandemic As a result of the ongoing novel coronavirus (or “COVID-19”) pandemic, the Company could experience impacts including, but not limited to, charges from potential adjustments of the carrying amounts of receivables and inventory, goodwill and other asset impairment charges, and deferred tax valuation allowances. There has been no material adverse impact to the Company’s consolidated financial statements for the year ended January 3, 2021; however, the extent to which the COVID-19 pandemic impacts the Company's business, results of operations, and financial condition will depend on future developments, which remain highly uncertain and cannot be predicted, including, but not limited to the duration, spread, and severity, of the COVID-19 pandemic, the effects of the COVID-19 pandemic on the Company's customers, suppliers, vendors, and associates and the remedial actions and stimulus measures adopted by local, state, and federal governments, and to what extent normal economic and operating conditions can resume. Even after the COVID-19 pandemic has subsided, the Company may experience an impact to its business as a result of any economic downturn, recession, or depression that has occurred or may occur in the future. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted which includes measures to assist companies in response to the COVID-19 pandemic. In accordance with the CARES Act, the Company has deferred the payment of qualifying employer payroll taxes which are required to be paid over two years, with 50 percent to be paid by December 31, 2021 and the remainder by December 31, 2022. As of January 3, 2021, the Company deferred $12.2 million of qualifying employer payroll taxes of which $6.1 million is included in Accrued compensation and $6.1 million is included in Other long-term liabilities in the Consolidated Balance Sheets, and $12.2 million is included in Accrued expenses and other liabilities within the Changes in operating assets and liabilities, net of the effects of acquisitions in the Consolidated Statements of Cash Flows. Basis of Financial Statement Presentation Holdings indirectly owns 100% of the membership interest in SiteOne Landscape Supply Holding, LLC (referred to herein as “Landscape Holding”). Landscape Holding is the parent and sole owner of SiteOne Landscape Supply, LLC (referred to herein as “Landscape”). Prior to the transaction described below, Deere & Company (“Deere”) was the sole owner of SiteOne Landscape Supply Holding, LLC. On December 23, 2013 (the “Closing Date”), the Company acquired 100% of the ownership interest in Landscape Holding from Deere in exchange for common shares of the Company initially representing 40% of the outstanding capital stock (on an as-converted basis) plus cash consideration of approximately $314 million, net of pre-closing and post-closing adjustments. In order to facilitate the transaction, the Company issued Redeemable Convertible Preferred Stock to Clayton, Dubilier & Rice, LLC (“CD&R”) for total consideration of $174 million initially representing 60% of the outstanding capital stock (on an as-converted basis). As part of the same transaction, Landscape Holding also acquired from Deere the affiliated company LESCO, Inc. (“LESCO”). The Company continues to be the sole owner of Landscape Holding. The aforementioned transactions described in this paragraph are referred to herein as the “CD&R Acquisition”. Following consummation of the secondary offering on July 26, 2017, CD&R and Deere no longer have an ownership interest in the Company. The Company’s chief operating decision maker (“CODM”) manages the business as a single reportable segment. Within the organizational framework, the same operational resources support multiple geographical regions and performance is evaluated primarily by the CODM at a consolidated level. The CODM also evaluates regional performance based on financial and operational measures and receives discrete financial information on a regional basis. Since all of the Company’s regions have similar operations and share similar economic characteristics, the Company aggregates regions into a single operating and reportable segment. These similarities include 1) long-term financial performance, 2) the nature of products and services, 3) the types of customers the Company sells to, and 4) the distribution methods used. Further, all of the Company’s product categories have similar supply chain processes, classes of customers, and economic characteristics. The accompanying audited consolidated financial statements of the Company included herein have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The Consolidated Statements of Operations, Comprehensive Income, Equity, and Cash Flows for the Company are presented for the fiscal years ended January 3, 2021, December 29, 2019, and December 30, 2018. The consolidated financial statements for the Company include the assets and liabilities used in operating the Company’s business, including entities in which the Company owns or controls more than 50% of the voting shares. All of the Company’s subsidiaries are wholly owned. All intercompany balances and transactions have been eliminated in consolidation. Significant accounting policies: Use of estimates in the preparation of financial statements : The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fiscal year : The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to December 31. The years ended January 3, 2021, December 29, 2019, and December 30, 2018 included 53 weeks, 52 weeks, and 52 weeks, respectively. Cash and cash equivalents : Cash and cash equivalents include primarily cash on deposit with banks which, at times, may exceed federally insured limits. The Company has not experienced any losses in these accounts. Cash and cash equivalents also include unsettled credit card transactions. Accounts receivable : The Company carries accounts receivable at the original invoice amount, less any charge-offs and the allowance for credit losses and doubtful accounts. Allowances for credit losses and doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions, credit risk quality, and reasonable supportable forecasts. Receivables are written-off to the allowance when an account is considered uncollectible. Activity in the allowance for doubtful accounts for the periods was as follows (in millions): For the year For the year For the year Beginning balance $ 8.3 $ 5.9 $ 4.7 Provision (reduction) for allowance 3.0 5.9 2.9 Write-offs, net of recoveries (2.2) (3.5) (1.7) Ending balance $ 9.1 $ 8.3 $ 5.9 Inventory : The majority of the Company’s inventories are valued at the lower of cost or net realizable value, with cost determined by the first-in, first-out (“FIFO”) method. Inventory is primarily considered to be finished goods. The Company establishes a reserve for excess, slow-moving, and obsolete inventory that is equal to the difference between the cost and estimated net realizable value for that inventory. These reserves are based on a review of planned and historical sales. The reserve for obsolete and excess inventory was approximately $7.9 million and $8.0 million as of January 3, 2021 and December 29, 2019, respectively. Property and equipment, net : Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed on property and equipment using the straight-line method over the estimated useful lives of the assets, as noted below. Leasehold improvements are depreciated over the lesser of their estimated useful lives or the remaining lease terms. The amortization of the right-of-use (“ROU”) assets under finance leases, which prior to fiscal year 2019 were known as capital leases, is included in amortization expense. Expenditures for replacement or major renewals of significant items are capitalized. Expenditures for maintenance, repairs, and minor renewals are generally charged to expense as incurred. Asset Class Estimated Useful Life Buildings and improvements 20 years Branch equipment 2 to 12 years Furniture and fixtures 2 to 12 years Auto and truck 2 to 6 years Tooling 7 years Leasehold improvements Shorter of the estimated useful life or the term of the lease, considering renewal options expected to be exercised. Acquisitions : When the Company acquires a controlling financial interest in an entity or group of assets that are determined to meet the definition of a business, the acquisition method described in ASC Topic 805, Business Combinations, is applied. The Company allocates the purchase consideration paid to acquire the business to the assets and liabilities acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. If during the measurement period (a period not to exceed 12 months from the acquisition date) the Company receives additional information that existed as of the acquisition date but at the time of the original allocation described above was unknown, the Company makes the appropriate adjustments to the purchase price allocation in the reporting period in which the adjustments are identified. Goodwill impairment : Goodwill represents the acquired fair value of a business in excess of the fair values of tangible and identified intangible assets acquired and liabilities assumed. The Company tests goodwill on an annual basis as of July fiscal month-end and additionally if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Examples of such indicators include a significant change in the business climate, unexpected competition, loss of key personnel or a decline in the Company’s market capitalization below the Company’s net book value. The Company performs impairment assessments at the reporting unit level, which is defined as an operating segment or one level below an operating segment, also known as a component. With the issuance of Accounting Standards Update 2017-04 Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) in January 2017, the impairment test is a single-step process. The process requires the Company to estimate and compare the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, the goodwill is not considered impaired. To the extent a reporting unit’s carrying amount exceeds its fair value, the reporting unit’s goodwill is deemed impaired, and an impairment charge is recognized based on the excess of a reporting unit’s carrying amount over its fair value . The Company adopted ASU 2017-04 in July 2017 with its annual goodwill impairment test. No impairment of goodwill has occurred during the periods presented. Refer to Note 5 for a more detailed description of goodwill. Intangible assets, net : Intangible assets include customer relationships, and trademarks and other intangibles, acquired through acquisitions. The fair value of customer relationships is determined using the multi-period excess earnings method, which is a specific discounted cash flow method that requires management to make significant estimates and assumptions, including the selection of the discount rates. Intangibles assets with finite useful lives are amortized on an accelerated method or a straight-line of amortization over their estimated useful lives. An accelerated amortization method reflecting the pattern in which the asset will be consumed is utilized if that pattern can be reliably determined. If that pattern cannot be reliably determined, a straight-line amortization method is used. The Company considers the period of expected cash flows and the underlying data used to measure the fair value of the intangible assets when selecting a useful life. The majority of customer relationships are amortized on an accelerated method. Refer to Note 5 for more information regarding intangible assets amortization. Impairment of long-lived assets : Long-lived assets, primarily property and equipment, finite-lived intangible assets, and long-term contracts included in other assets, are evaluated for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The recoverability of an asset group is measured by a comparison of the carrying amount of the asset group to its future undiscounted cash flows. If the recoverability test indicates the asset group balances are not recoverable, the Company would recognize an impairment charge to reduce the long-lived asset balances based on the fair value of the asset group. The amount of such impairment would be charged to operations in the current period. There were no impairment charges recognized during the years ended January 3, 2021, December 29, 2019, and December 30, 2018. Fair value measurement : Fair value is defined as an exit price, representing an amount that would be received to sell an asset or the amount paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The inputs used to measure fair value are prioritized into the following three-tiered value hierarchy: • Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active or inputs, other than quoted prices in active markets, which are observable either directly or indirectly. • Level 3: Unobservable inputs for which there is little or no market data. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurement within the hierarchy is based upon the lowest level of input that is significant to the measurement. The Company’s financial instruments consist of cash and cash equivalents, accounts receivables, and long-term debt. The variable interest rate on the long-term debt is reflective of current market borrowing rates. As such, the Company has determined that the carrying value of these financial instruments approximates fair value. Interest Rate Swaps : The Company is subject to interest rate risk with regard to existing and future issuances of debt. The Company utilizes interest rate swap contracts to reduce its exposure to fluctuations in variable interest rates for future interest payments on existing debt. The Company is party to various forward-starting interest rate swap contracts to convert the variable interest rate to a fixed interest rate on the borrowings under the Term Loan Facility. The Company recognizes the unrealized gains or unrealized losses as either assets or liabilities at fair value on its Consolidated Balance Sheets. The forward-starting interest rate swap contracts are subject to master netting arrangements. The Company has elected not to offset the fair value of assets with the fair value of liabilities related to these contracts. For determining the fair value of the interest rate swap contracts, the Company uses significant observable market data or assumptions (Level 2 inputs) that market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. The 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 Company recognizes any differences between the variable interest rate payments and the fixed interest rate settlements with the swap counterparties as an adjustment to interest expense over the life of the swaps. The Company has designated these swaps as cash flow hedges and records the estimated fair value of the swaps to Accumulated other comprehensive income (loss) (“AOCI”) on its Consolidated Balance Sheets. If it becomes probable the forecasted transactions will not occur, the hedge relationship will be de-designated and amounts accumulated in AOCI will be reclassified to Interest and other non-operating expenses, net in the current period. Future changes in the fair value of derivatives not designated as hedging instruments will be reported in Interest and other non-operating expenses, net in the Consolidated Statements of Operations. Revenue recognition : The Company recognizes revenue when control over a product or service is transferred to a customer. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. Revenue is measured at the transaction price, which is based on the amount of consideration the Company expects to receive in exchange for transferring the promised goods or services to the customer. The transaction price will include estimates of variable consideration, such as returns and provisions for doubtful accounts and sales incentives, to the extent it is probable that a significant reversal of revenue recognized will not occur. In all cases, when a sale is recorded by the Company, no significant uncertainty exists surrounding the purchaser’s obligation to pay. Net sales include billings for freight and handling charges and commissions on the sale of control products that we sell as an agent. Net sales are presented net of any discounts, returns, customer rebates, and sales or other revenue-based taxes. Provisions for returns are estimated and accrued at the time a sale is recognized. The Company also has entered into agency agreements with certain of its suppliers whereby the Company operates as a sales agent of those suppliers. The suppliers retain title to their merchandise until it is sold by the Company and determine the prices at which the Company can sell their merchandise. The Company recognizes these agency sales on a net basis and records only the product margin as commission revenue within Net sales. Sales incentives : The Company offers certain customers rebates which are accrued based on sales volumes. In addition, the Company offers a points-based reward program which allows enrolled customers to earn loyalty rewards on purchases to be used on future purchases, to pay for annual customer trips hosted by the Company, or to obtain gift cards to other third-party retailers. The Company often receives cash payments from customers in advance of the Company’s performance of the customer loyalty reward program resulting in contract liabilities. These contract liabilities are classified as current in the Company’s Consolidated Balance Sheets. Contract liabilities are reported on the Company’s Consolidated Balance Sheets on a contract-by-contract basis. Sales taxes : The Company collects and remits taxes assessed by different governmental authorities that are both imposed on and concurrent with revenue producing transactions between the Company and its customers. These taxes may include sales, use, value-added, and some excise taxes. The Company reports the collection of these taxes on a net basis (excluded from sales). Cost of goods sold : Cost of goods sold includes all inventory costs, such as purchase price from suppliers, net of any volume-based incentives, as well as inbound freight and handling, and other costs associated with the inventory, and is exclusive of the costs to deliver the products to customers. Shipping and handling costs : Shipping and handling costs associated with inbound freight are included in Cost of goods sold. Warranty reserves : Provisions for estimated warranty costs for the return of nursery products are provided for in the same period the related sales are recorded. The Company offers product warranties on selected nursery items. The warranty reserve is based on historical and current trends. The warranty reserve included in Accrued liabilities was approximately $0.1 million and $0.2 million as of January 3, 2021 and December 29, 2019, respectively. Leases : The Company determines if an arrangement is a lease at inception of a contract. The Company leases equipment and real estate including office space, branch locations, and distribution centers under operating leases. Finance lease obligations consist primarily of the Company’s vehicle fleet. Most real estate leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 5 years or more. The exercise of lease renewal options is at the Company’s sole discretion. Certain leases include options to purchase the leased property. The lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded in the Consolidated Balance Sheets. The Company has elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component. The Company also elected the package of practical expedients, which among other things, allows the Company to carry forward historical lease classification. Variable lease payment amounts that cannot be determined at the commencement of the lease such as increases in lease payments based on changes in index rates or usage, are not included in the ROU assets or lease liabilities. These payments are expensed as incurred and recorded as variable lease expense. ROU assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the net present value of fixed lease payments over the lease term. ROU assets also include any advance lease payments and are adjusted for lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Operating fixed lease expense and finance lease amortization expense are recognized on a straight-line basis over the lease term. Refer to Note 6 for further details regarding leases. Advertising costs : Advertising costs are charged to expense as incurred and were approximately $4.7 million, $3.3 million, and $3.1 million, during the years ended January 3, 2021, December 29, 2019, and December 30, 2018, respectively. Stock-based compensation : The Company applies the fair value method to recognize compensation expense for stock-based awards. Using this method, the estimated grant-date fair value of the award is recognized on a straight-line basis over the requisite service period based on the portion of the award that is expected to vest. Stock-based compensation expense for restricted stock units is measured based on the fair value of the Company’s common stock on the grant date. The Company utilizes the Black-Scholes option pricing model to estimate the grant-date fair value of option awards. The exercise price of option awards is set to equal the value of the common stock at the date of the grant. The following weighted-average assumptions are also used to calculate the estimated fair value of option awards: • Expected volatility: The expected volatility of the Company’s shares is estimated using the historical stock price volatility over the most recent period commensurate with the estimated expected term of the awards. • Expected term: For employee stock option awards, the Company determines the weighted average expected term equal to the weighted period between the vesting period and the contract life of all outstanding options. • Dividend yield: The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. • Risk-free interest rate: The Company bases the risk-free interest rate on the implied yield available on a U.S. Treasury note with a term equal to the estimated expected term of the awards. Refer to Note 7 for further details regarding stock-based compensation. Other income : Other income consists primarily of financing charges, net gain/loss on sale of assets, foreign currency gain/loss, and the fair value adjustments of acquisition related contingent obligations. Income taxes : The Company files a consolidated federal income tax return and files both combined or unitary state income tax returns as well as separate state income tax returns in certain jurisdictions. Deferred taxes are provided on an asset and liability method in which deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Realization of deferred tax assets is dependent upon sufficient future taxable income. The Company’s operations involve dealing with uncertainties and judgments in the application of complex tax regulations in a multitude of jurisdictions. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return based on its estimate of whether, and the extent to which, additional taxes will be due. The Company recognizes interest, if any, related to unrecognized tax benefits within Interest and other non-operating expenses, and recognizes penalties in Selling, general and administrative expenses. In December 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted, which included several changes to existing U.S. tax laws that impacted the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21%. The reduced tax rate is reflected in the Company’s Income tax expense for the years ended January 3, 2021, December 29, 2019, and December 30, 2018, respectively. In March 2020, the CARES Act was enacted. The CARES Act included several changes to existing U.S. tax laws that impacted the Company, most notably the 2019 and 2020 change to the limitation on U.S. interest deductibility based on 50% of adjusted taxable income, the ability to defer the payment of qualifying employer payroll taxes to December 31, 2021 and December 31, 2022, and certain changes to the depreciable life of qualified improvement property. Refer to Note 9 for further information pertaining to income taxes. Foreign currency translation : The functional currency for the Company’s Canadian operations is the Canadian dollar, the local currency. The assets and liabilities of these operations are translated into U.S. dollars at the end of the period exchange rates. The revenues and expenses are translated at average exchange rates for the period. The gains or losses from these translations are recorded in other comprehensive income (loss). Gains or losses recognized on transactions denominated in a currency other than the functional currency are included in Other income. Recently Issued and Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which amended existing revenue recognition standards and established a new Accounting Standards Codification (“ASC”) Topic 606. The core principle of this amendment was that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for these goods or services. The Company adopted ASU 2014-09 and related amendments in the first quarter of fiscal year 2018 using the modified retrospective transition method. The Company concluded that it had substantially similar performance obligations under the amended guidance as compared with deliverables and units of account previously recognized. Additionally, the Company made policy elections within the amended standard that are consistent with its current accounting. The adoption of ASU 2014-09 resulted in additional revenue recognition disclosures (refer to Note 2 ), and had an immaterial impact on the timing of revenue recognition related to its customer loyalty rewards program. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings in the first quarter of 2018. The adoption of ASC 606 did not have a significant impact on the Company’s consolidated financial statements. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. In August 2016, the FASB issued ASU 2016-15, “ Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and |
