| Significant Accounting Policies | Significant Accounting Policies: Nature of Business Tractor Supply Company is the largest operator of rural lifestyle retail stores in the United States. The Company is focused on supplying the needs of recreational farmers and ranchers and those who enjoy the rural lifestyle, as well as tradesmen and small businesses. Stores are located primarily in towns outlying major metropolitan markets and in rural communities. At December 26, 2015 , the Company operated a total of 1,488 retail stores in 49 states and also offered a number of products online at TractorSupply.com . Fiscal Year The Company’s fiscal year includes 52 or 53 weeks and ends on the last Saturday of the calendar year. The fiscal years ended December 26, 2015 , December 27, 2014 , and December 28, 2013 consisted of 52 weeks. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated. Management Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States inherently requires estimates and assumptions by management of the Company that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures. Actual results could differ from those estimates. Significant estimates and assumptions by management primarily impact the following key financial statement areas: Inventory Valuation Inventory Impairment Risk The Company identifies potentially excess and slow-moving inventory by evaluating turn rates, historical and expected future sales trends, age of merchandise, overall inventory levels, current cost of inventory and other benchmarks. The Company has established an inventory valuation reserve to recognize the estimated impairment in value (i.e. an inability to realize the full carrying value) based on the Company’s aggregate assessment of these valuation indicators under prevailing market conditions and current merchandising strategies. The Company does not believe its merchandise inventories are subject to significant risk of obsolescence in the near term. However, changes in market conditions or consumer purchasing patterns could result in the need for additional reserves. Shrinkage The Company performs physical inventories at each store at least once a year, and the Company has established a reserve for estimating inventory shrinkage between physical inventory counts. The reserve is established by assessing the chain-wide average shrinkage experience rate, applied to the related periods’ sales volumes. Such assessments are updated on a regular basis for the most recent individual store experiences. The estimated store inventory shrink rate is based on historical experience. The Company believes historical rates are a reasonably accurate reflection of future trends. Vendor Funding The Company receives funding from substantially all of its significant merchandise vendors, in support of its business initiatives, through a variety of programs and arrangements, including guaranteed vendor support funds (“vendor support”) and volume-based rebate funds (“volume rebates”). The amounts received are subject to terms of vendor agreements, most of which are “evergreen”, reflecting the on-going relationship with our significant merchandise vendors. Certain of the Company’s agreements, primarily volume rebates, are renegotiated annually, based on expected annual purchases of the vendor’s product. Vendor funding is initially deferred as a reduction of the purchase price of inventory and then recognized as a reduction of cost of merchandise as the related inventory is sold. During interim periods, the amount of vendor support and volume rebates are estimated based upon initial commitments and anticipated purchase levels with applicable vendors. The estimated purchase volume (and related vendor funding) is based on the Company’s current knowledge of inventory levels, sales trends and expected customer demand, as well as planned new store openings and relocations. Although the Company believes it can reasonably estimate purchase volume and related volume rebates at interim periods, it is possible that actual year-end results could be different from previously estimated amounts. Freight The Company incurs various types of transportation and delivery costs in connection with inventory purchases and distribution. Such costs are included as a component of the overall cost of inventories (on an aggregate basis) and recognized as a component of cost of merchandise sold as the related inventory is sold. Self-Insurance Reserves The Company self-insures a significant portion of its employee medical insurance, workers’ compensation insurance and general liability (including product liability) insurance plans. The Company has stop-loss insurance policies to protect it from individual losses over specified dollar values. For self-insured employee medical claims, we have a stop loss limit of $300,000 per person per year. Our deductible or self-insured retention, as applicable, for each claim involving workers’ compensation insurance and general liability insurance is limited to $500,000 and our Texas Work Injury Policy is limited to $750,000 . Further, we maintain a commercially reasonable umbrella/excess policy that covers liabilities in excess of the primary insurance policy limits. The full extent of certain claims, especially workers’ compensation and general liability claims, may not become fully determined for several years. Therefore, the Company estimates potential obligations based upon historical claims experience, industry factors, severity factors and other actuarial assumptions. Although the Company believes the reserves established for these obligations are reasonably estimated, any significant change in the number of claims or costs associated with claims made under these plans could have a material effect on the Company’s financial results. At December 26, 2015 , the Company had recorded net insurance reserves of $51.2 million compared to $48.3 million at December 27, 2014 . Sales Tax Audit Reserve A portion of the Company’s sales are to tax-exempt customers, predominantly agricultural-based . The Company obtains exemption information as a necessary part of each tax-exempt transaction. Many of the states in which the Company conducts business will perform audits to verify the Company’s compliance with applicable sales tax laws. The business activities of the Company’s customers and the intended use of the unique products sold by the Company create a challenging and complex tax compliance environment. These circumstances also create some risk that the Company could be challenged as to the accuracy of the Company’s sales tax compliance. The Company reviews past audit experience and assessments with applicable states to continually determine if it has potential exposure for non-compliance. Any estimated liability is based on an initial assessment of compliance risk and historical experience with each state. The Company continually reassesses the exposure based on historical audit results, changes in policies, preliminary and final assessments made by state sales tax auditors, and additional documentation that may be provided to reduce the assessment. The reserve for these tax audits can fluctuate depending on numerous factors, including the complexity of agricultural-based exemptions, the ambiguity in state tax regulations, the number of ongoing audits and the length of time required to settle with the state taxing authorities. Tax Contingencies The Company’s income tax returns are periodically audited by U.S. federal and state tax authorities. These audits include questions regarding tax filing positions, including the timing and amount of deductions and the allocation of income among various tax jurisdictions. At any time, multiple tax years are subject to audit by the various tax authorities. In evaluating the exposures associated with the Company’s various tax filing positions, the Company records a liability for uncertain tax positions taken or expected to be taken in a tax return. A number of years may elapse before a particular matter, for which the Company has established a reserve, is audited and fully resolved or clarified. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company adjusts its tax contingencies reserve and income tax provision in the period in which actual results of a settlement with tax authorities differs from the established reserve, the statute of limitations expires for the relevant tax authority to examine the tax position or when more information becomes available. The Company’s tax contingencies reserve contains uncertainties because management is required to make assumptions and apply judgment to estimate the exposures associated with the Company’s various filing positions and whether or not the minimum requirements for recognition of tax benefits have been met. The effective income tax rate is also affected by changes in tax law, the tax jurisdiction of new stores or business ventures, the level of earnings and the results of tax audits. Impairment of Long-Lived Assets Long-lived assets other than goodwill and indefinite-lived intangible assets, which are separately tested for impairment, are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. When evaluating long-lived assets for potential impairment, the Company first compares the carrying value of the asset to the asset’s estimated undiscounted future cash flows. The evaluation for long-lived assets is performed at the lowest level of identifiable cash flows, which is generally the individual store level. The significant assumptions used to determine estimated undiscounted cash flows include cash inflows and outflows directly resulting from the use of those assets in operations, including margin on net sales, payroll and related items, occupancy costs, insurance allocations and other costs to operate a store. If the estimated future cash flows are less than the carrying value of the asset, the Company calculates an impairment loss. The impairment loss calculation compares the carrying value of the asset to the asset’s estimated fair value, which may be based on an estimated future cash flow model. The Company recognizes an impairment loss if the amount of the asset’s carrying value exceeds the asset’s estimated fair value. If the Company recognizes an impairment loss, the adjusted carrying amount of the asset becomes its new cost basis. For a depreciable long-lived asset, the new cost basis will be depreciated (amortized) over the remaining estimated useful life of that asset. No significant impairment charges were recognized in fiscal 2015 , 2014 and 2013 . Impairment charges are included in selling, general and administrative (“SG&A”) expenses in the Consolidated Statements of Income. Revenue Recognition and Sales Returns The Company recognizes revenue at the time the customer takes possession of merchandise. If the Company receives payment before completion of its customer obligations (as per the Company’s special order and layaway programs), the revenue is deferred until the customer takes possession of the merchandise and the sale is complete. The Company is required to collect certain taxes and fees from customers on behalf of government agencies and remit such collections to the applicable governmental entity on a periodic basis. These taxes are collected from customers at the time of purchase, but are not included in net sales. The Company records a liability upon collection from the customer and relieves the liability when payments are remitted to the applicable governmental agency. The Company estimates a liability for sales returns based on a rolling average of historical return trends, and the Company believes that its estimate for sales returns is an accurate reflection of future returns associated with past sales. However, as with any estimate, refund activity may vary from estimated amounts. At December 26, 2015 , the Company had a liability of $3.3 million reserved for sales returns compared to $3.2 million at December 27, 2014 . The Company recognizes revenue when a gift card or merchandise return card is redeemed by the customer and recognizes income when the likelihood of the gift card or merchandise return card being redeemed by the customer is remote (referred to as “breakage”). The gift cards and merchandise return card breakage rate is based upon historical redemption patterns and income is recognized for unredeemed gift cards and merchandise return cards in proportion to those historical redemption patterns. The Company recognized breakage income of $1.6 million , $0.9 million and $1.6 million in fiscal 2015 , 2014 and 2013 , respectively. Cost of Merchandise Sold Cost of merchandise sold includes the total cost of products sold; freight expenses associated with moving merchandise inventories from vendors to distribution facilities, from distribution facilities to retail stores, and from one distribution facility to another; vendor support; damaged, junked or defective product; cash discounts from payments to merchandise vendors; and adjustments for shrinkage (physical inventory losses), lower of cost or net realizable value, slow moving product and excess inventory quantities. Selling, General and Administrative Expenses SG&A expenses include payroll and benefit costs for retail, distribution facility and corporate employees; occupancy costs of retail, distribution and corporate facilities; advertising; tender costs, including bank charges and costs associated with credit and debit card interchange fees; outside service fees; and other administrative costs, such as computer maintenance, supplies, travel and lodging. Advertising Costs Advertising costs consist of expenses incurred in connection with newspaper circulars and customer-targeted direct mail, as well as limited television, radio and other promotions. Costs are expensed when incurred with the exception of television advertising and circular and direct mail promotions, which are expensed upon first showing. Advertising expenses for fiscal 2015 , 2014 and 2013 were approximately $73.9 million , $70.4 million and $65.6 million , respectively. Prepaid advertising costs were approximately $1.6 million and $0.5 million at December 26, 2015 and December 27, 2014 , respectively. Warehousing and Distribution Facility Costs Costs incurred at the Company’s distribution facilities for receiving, warehousing and preparing product for delivery are expensed as incurred and are included in SG&A expenses in the Consolidated Statements of Income. Because the Company does not include these costs in cost of sales, the Company’s gross margin may not be comparable to other retailers that include these costs in the calculation of gross margin. Distribution facility costs including depreciation for fiscal 2015 , 2014 and 2013 were approximately $145.4 million , $121.1 million and $111.3 million , respectively. Pre-opening Costs Non-capital expenditures incurred in connection with opening new stores, primarily payroll and rent, are expensed as incurred. Pre-opening costs were approximately $9.6 million , $8.9 million and $7.8 million in fiscal 2015 , 2014 and 2013 , respectively. Share-Based Compensation The Company has share-based compensation plans covering certain members of management and non-employee directors, which include incentive and non-qualified stock options and restricted stock units. In addition, the Company offers an Employee Stock Purchase Plan (“ESPP”) to most employees that work at least 20 hours per week. The Company estimates the fair value of its stock option awards at the date of grant utilizing a Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of short-term traded options that have no vesting restrictions and are fully transferable. However, key assumptions used in the Black-Scholes model are adjusted to incorporate the unique characteristics of the Company’s stock option awards. Option pricing models and generally accepted valuation techniques require management to make subjective assumptions including expected stock price volatility, expected dividend yield, risk-free interest rate and expected life. The Company relies on a blended volatility approach, weighting historical volatility trends and implied volatility, to estimate future volatility assumptions. The risk-free interest rates used were actual U.S. Treasury Constant Maturity rates for bonds matching the expected term of the option on the date of grant. The expected term of the option on the date of grant was estimated based on the Company’s historical experience for similar options. In addition to the key assumptions used in the Black-Scholes model, the estimated forfeiture rate at the time of valuation (which is based on historical experience for similar options) is a critical assumption, as it reduces expense ratably over the vesting period. The Company adjusts this estimate periodically, based on the extent to which actual forfeitures differ, or are expected to differ, from the previous estimate. The fair value of the Company’s restricted stock unit awards is the closing price of the Company’s common stock the day preceding the grant date. The Company believes its estimates are reasonable in the context of historical experience. Future results will depend on, among other matters, levels of share-based compensation granted in the future, actual forfeiture rates and the timing of option exercises. Depreciation and Amortization Depreciation includes expenses related to all retail, distribution facility and corporate assets. Amortization includes expenses related to definite-lived intangible assets. Income Taxes The Company uses the asset and liability method to account for income taxes whereby deferred tax assets and liabilities are determined based on differences between the financial carrying amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates and laws that are anticipated to be in effect when temporary differences reverse or are settled. The effect of a tax rate change is recognized in the period in which the law is enacted in the provision for income taxes. The Company records a valuation allowance when it is more likely than not that a deferred tax asset will not be realized. Net Income Per Share Basic net income per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average diluted shares outstanding. Dilutive shares are computed using the treasury stock method for stock options and restricted stock units. Comprehensive Income The Company’s comprehensive income is equal to net income in fiscal 2015 , 2014 and 2013 . Cash and Cash Equivalents Temporary cash investments, with a maturity of three months or less when purchased, are considered to be cash equivalents. The majority of payments due from banks for customer credit cards are classified as cash and cash equivalents, as they generally settle within 24 - 48 hours. Sales generated through the Company’s private label credit cards are not reflected as accounts receivable. Under an agreement with Citi Cards, a division of Citigroup, consumer and business credit is extended directly to customers by Citigroup. All credit program and related services are performed and controlled directly by Citigroup. Payments due from Citigroup are classified as cash and cash equivalents as they generally settle within 24 - 48 hours. Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s financial instruments consist of cash and cash equivalents, short-term receivables, trade payables and long-term debt instruments. Due to their short-term nature, the carrying values of cash and cash equivalents, short-term receivables and trade payables approximate current fair value at each balance sheet date. The Company had $150.0 million in borrowings under the 2011 Senior Credit Facility (as defined in Note 3) at December 26, 2015 and no borrowings as of December 27, 2014 . Based on current market interest rates (Level 2 inputs), the carrying value of our borrowings under the 2011 Senior Credit Facility approximates fair value as of December 26, 2015. Inventories Inventories are stated at the lower of cost, as determined by the average cost method, or net realizable value. Inventory cost consists of the direct cost of merchandise including freight. Inventories are net of shrinkage, obsolescence, other valuations and vendor allowances. Property and Equipment Property and equipment are carried at cost. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. Improvements to leased premises are amortized using the straight-line method over the initial term of the lease or the useful life of the improvement, whichever is less. Leasehold improvements added late in the lease term are amortized over the term of the lease (including the first renewal option, if the renewal is reasonably assured) or the useful life of the improvement, whichever is less. The following estimated useful lives are generally applied: Life Buildings 30 – 35 years Leasehold and building improvements 5 – 35 years Furniture, fixtures and equipment 5 – 10 years Computer software and hardware 3 – 5 years The Company entered into agreements with various governmental entities in the states of Kentucky, Georgia and Tennessee to implement tax abatement plans related to its distribution center in Franklin, Kentucky (Simpson County), its distribution center in Macon, Georgia (Bibb County) and its Store Support Center in Brentwood, Tennessee (Williamson County). The tax abatement plans provide for reduction of real property taxes for specified time frames by legally transferring title to its real property in exchange for industrial revenue bonds. This property was then leased back to the Company. No cash was exchanged. The lease payments are equal to the amount of the payments on the bonds. The tax abatement period extends through the term of the lease, which coincides with the maturity date of the bonds. At any time, the Company has the option to purchase the real property by paying off the bonds, plus $1 . The terms and amounts authorized and drawn under each industrial revenue bond agreement are outlined as follows, as of December 26, 2015 : Bond Term Bond Authorized Amount (in millions) Amount Drawn (in millions) Franklin, Kentucky Distribution Center 30 years $ 54.0 $ 51.8 Macon, Georgia Distribution Center 15 years $ 58.0 $ 49.9 Brentwood, Tennessee Store Support Center 10 years $ 78.0 $ 75.3 Due to the form of these transactions, the Company has not recorded the bonds or the lease obligation associated with the sale lease-back transaction. The original cost of the Company’s property and equipment is recorded on the balance sheet and is being depreciated over its estimated useful life. Capitalized Software Costs The Company capitalizes certain costs related to the acquisition and development of software and amortizes these costs using the straight-line method over the estimated useful life of the software, which is three to five years. Computer software consists primarily of third-party software purchased for internal use. A subsequent addition, modification or upgrade to internal-use software is capitalized to the extent that it enhances the software’s functionality or extends its useful life. These costs are included in computer software and hardware in the accompanying Consolidated Balance Sheets. Certain software costs not meeting the criteria for capitalization are expensed as incurred. Goodwill All goodwill is associated with the Company as a whole. Goodwill is not amortized, but is evaluated for impairment annually and whenever events or changes in circumstances indicate the carrying value of the goodwill may not be recoverable. The Company completes its impairment evaluation by performing internal valuation analyses and considering other publicly available market information, as appropriate. The test for goodwill impairment is a two step process. The first step of the goodwill impairment test, used to identify the potential for impairment, compares the fair value of a reporting unit with the carrying value of its net assets, including goodwill. If the fair value of the reporting unit is less than the carrying value of the reporting unit, the second step of the goodwill impairment test is performed to measure the amount of impairment loss to be recorded, if any. The second step, if required, would compare the implied fair value of goodwill with the current carrying amount of goodwill. If the implied fair value of goodwill is less than the carrying value, an impairment charge would be recorded as a charge to the Company’s operations. In the fourth quarter of fiscal 2015 , the Company completed its annual impairment testing of goodwill and no impairment was identified. The Company determined that the fair value of the reporting unit (including goodwill) was in excess of the carrying value of the reporting unit and as such, the second step was not necessary. In reaching this conclusion, the fair value of the reporting unit was determined based on a market approach. Under the market approach, the fair value is based on observed market prices. Store Closing Costs The Company regularly evaluates the performance of its stores and periodically closes those that are under-performing. The Company records a liability for costs associated with an exit or disposal activity when the liability is incurred, usually in the period the store closes. Store closing costs were not significant to results of operations for any of the fiscal years presented. Leases Assets under capital leases are amortized in accordance with the Company’s normal depreciation policy for owned assets or over the lease term, if shorter, and the related charge to operations is included in depreciation expense in the Consolidated Statements of Income. Certain operating leases include rent increases during the lease term. For these leases, the Company recognizes the related rental expense on a straight-line basis over the term of the lease (which includes the pre-opening period of construction, renovation, fixturing and merchandise placement) and records the difference between the expense charged to operations and amounts paid as a deferred rent liability. The Company occasionally receives reimbursements from landlords to be used towards improving the related store to be leased. Leasehold improvements are recorded at their gross costs including items reimbursed by landlords. Related reimbursements are deferred and amortized on a straight-line basis as a reduction of rent expense over the applicable lease term. |
