SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Description of Business
Dollar Tree, Inc. (the Company) is a leading operator of discount retail stores in the United States and Canada. Below are those accounting policies considered by the Company to be significant.
Acquisition
On July 6, 2015, the Company acquired Family Dollar Stores, Inc. ("Family Dollar") for cash consideration of $6.8 billion and the issuance of 28.5 million shares of the Company's common stock valued at $2.3 billion based on the closing price of the Company's common stock on July 2, 2015 (the "Acquisition"). The results of operations of Family Dollar are included in the Company's results of operations beginning on July 6, 2015 (the "Acquisition Date").
Principles of Consolidation
The consolidated financial statements include the financial statements of Dollar Tree, Inc., and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Segment Information
At January 28, 2017, the Company operates more than 14,300 discount retail stores in 48 states and five Canadian provinces. The Company's operations are conducted in two reporting business segments: Dollar Tree and Family Dollar. The Company defines its segments as those operations whose results its chief operating decision maker ("CODM") regularly reviews to analyze performance and allocate resources. The results of operations of Family Dollar are included in the Company's results of operations beginning on July 6, 2015.
The Dollar Tree segment is the leading operator of discount variety stores offering merchandise at the fixed price of $1.00. The Dollar Tree segment includes the Company's operations under the "Dollar Tree" and "Dollar Tree Canada" brands, eleven distribution centers in the United States, two distribution centers in Canada and a Store Support Center in Chesapeake, Virginia.
The Family Dollar segment operates a chain of general merchandise discount retail stores providing consumers with a selection of competitively-priced merchandise in convenient neighborhood stores. The Family Dollar segment consists of the Company's operations under the "Family Dollar" brand, eleven distribution centers and a Store Support Center in Matthews, North Carolina.
Foreign Currency
The functional currencies of certain of the Company’s international subsidiaries are the local currencies of the countries in which the subsidiaries are located. Foreign currency denominated assets and liabilities are translated into U.S. dollars using the exchange rates in effect at the consolidated balance sheet date. Results of operations and cash flows are translated using the average exchange rates throughout the period. The effect of exchange rate fluctuations on translation of assets and liabilities is included as a component of shareholders’ equity in accumulated other comprehensive loss. Gains and losses from foreign currency transactions, which are included in "Other (income) expense, net" have not been significant.
Fiscal Year
The Company's fiscal year ends on the Saturday closest to January 31. Any reference herein to "2016" or "Fiscal 2016," “2015” or “Fiscal 2015,” and “2014” or “Fiscal 2014,” relates to as of or for the year ended January 28, 2017, January 30, 2016, and January 31, 2015, respectively. Each fiscal year included 52 weeks. "2017" or "Fiscal 2017" ends on February 3, 2018 and will include 53 weeks, commensurate with the retail calendar.
Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Purchase Price Allocation
Determining the fair value of certain assets and liabilities acquired is subjective in nature and often involves the use of significant estimates and assumptions, which are inherently uncertain. Many of the estimates and assumptions used to determine fair values, such as those used for intangible assets, are made based on forecasted information and discount rates. In addition, the judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations. To assist in the purchase price allocation for the Acquisition, the Company engaged a third-party appraisal firm. See Note 2 for more information regarding the Acquisition.
Cash and Cash Equivalents
Cash and cash equivalents at January 28, 2017 and January 30, 2016 includes $554.4 million and $462.9 million, respectively, of investments primarily in money market securities which are valued at cost, which approximates fair value. For purposes of the consolidated statements of cash flows, the Company considers all highly-liquid debt instruments with original maturities of 3 months or less to be cash equivalents. The majority of payments due from financial institutions for the settlement of debit card and credit card transactions process within 3 business days, and therefore are classified as cash and cash equivalents.
Merchandise Inventories
Merchandise inventories at the Company’s distribution centers are stated at the lower of cost or market, determined on a weighted-average cost basis. Cost is assigned to store inventories using the retail inventory method on a weighted-average basis. Under the retail inventory method, the valuation of inventories at cost and the resulting gross margins are computed by applying a calculated cost-to-retail ratio to the retail value of inventories.
Costs directly associated with warehousing and distribution are capitalized as merchandise inventories. Total warehousing and distribution costs capitalized into inventory amounted to $116.9 million and $114.0 million at January 28, 2017 and January 30, 2016, respectively.
Property, Plant and Equipment
Property, plant and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the respective assets as follows:
Buildings
39 to 40 years
Furniture, fixtures and equipment
3 to 15 years

Leasehold improvements are amortized over the estimated useful lives of the respective assets or the committed terms of the related leases, whichever is shorter. Amortization is included in "Selling, general and administrative expenses" in the accompanying consolidated income statements.
Costs incurred related to software developed for internal use are capitalized and amortized, generally over three years.
Capitalized Interest
The Company capitalizes interest on borrowed funds during the construction of certain property and equipment. The Company capitalized $2.4 million and $1.3 million of interest costs in the years ended January 28, 2017 and January 30, 2016, respectively. No interest costs were capitalized in the year ended January 31, 2015.
Goodwill and Nonamortizing Intangible Assets
Goodwill and nonamortizing intangible assets are not amortized, but rather tested for impairment at least annually. In addition, goodwill and nonamortizing intangible assets will be tested on an interim basis if an event or circumstance indicates that it is more likely than not that an impairment loss has been incurred. The Company performed its annual impairment testing in November 2016 and determined that no impairment existed.
Other Assets
Other assets historically consisted primarily of restricted investments and deferred compensation plan assets. Restricted investments were purchased to collateralize long-term insurance obligations. In 2016, the Company liquidated its restricted investments and began to use standby letters of credit to collateralize long-term insurance obligations. No restricted investments existed at January 28, 2017. As of January 30, 2016, the Company held $82.0 million of restricted investments. These investments were primarily in tax-exempt money market funds that invested in short-term municipal obligations. These investments were classified as available-for-sale and were recorded at fair value, which approximated cost. Deferred compensation plan assets were $19.8 million and $21.1 million at January 28, 2017 and January 30, 2016, respectively, and are recorded at fair value.
Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of
The Company reviews its long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets based on discounted cash flows or other readily available evidence of fair value, if any. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. In fiscal 2016, 2015 and 2014, the Company recorded charges of $3.7 million, $1.6 million and $1.5 million, respectively, to write down certain assets. These charges are recorded as a component of "Selling, general and administrative expenses" in the accompanying consolidated income statements.
Financial Instruments
The Company utilizes derivative financial instruments to reduce its exposure to market risks from changes in interest rates and diesel fuel costs. By entering into receive-variable, pay-fixed interest rate and diesel fuel swaps, the Company limits its exposure to changes in variable interest rates and diesel fuel prices. The Company is exposed to credit-related losses in the event of non-performance by the counterparty to these instruments but minimizes this risk by entering into transactions with high quality counterparties. Interest rate or diesel fuel cost differentials paid or received on the swaps are recognized as adjustments to interest in the period earned or incurred. The Company formally documents all hedging relationships, if applicable, and assesses hedge effectiveness both at inception and on an ongoing basis.  
Fair Value Measurements
Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a fair value hierarchy has been established that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurement) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are as follows:
Level 1 - Quoted prices in active markets for identical assets or liabilities;
Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and
Level 3 - Unobservable inputs in which there is little or no market data which require the reporting entity to develop its own assumptions.
As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.
The following table sets forth the Company's financial assets and liabilities that are accounted for at fair value on a recurring basis:

3,886.1


The Company’s cash and cash equivalents are valued at cost, which approximates fair value, due to the short-term maturities of these instruments.
The fair values of the diesel fuel swaps were estimated using discounted cash flow calculations based upon forward interest-rate yield and diesel cost curves. The curves were obtained from independent pricing services reflecting broker market quotes. As of January 28, 2017, the Company did not have any diesel fuel swaps outstanding.
The fair values of the Company's Secured Senior Notes and Acquisition Notes were determined using Level 1 inputs as quoted prices in active markets for identical assets or liabilities are available. The fair values of the Company's term loans were determined using Level 2 inputs as quoted prices are readily available from pricing services, but the prices are not published. The carrying values of the Company's Tranche A Revolving Credit Facility at January 28, 2017 and the Company's Revolving Credit Agreement at January 30, 2016, approximated their fair values because the interest rates vary with market interest rates.
Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). The Company recorded impairment charges of $0.7 million, $1.6 million, and $1.5 million in fiscal 2016, 2015 and 2014, respectively, to reduce certain store assets to their estimated fair values. The fair values were determined based on the income approach, in which the Company utilized internal cash flow projections over the life of the underlying lease agreements discounted based on a risk-free rate of return. These measures of fair value, and related inputs, are considered a Level 3 approach under the fair value hierarchy. There were no other changes related to Level 3 assets. The Company also recorded impairment charges of $3.0 million to reduce certain assets held for sale to their estimated fair values. The fair values were determined based on the market prices of identical assets. The measures of fair value are considered a Level 1 approach under the fair value hierarchy.
Lease Accounting
The Company generally leases its retail locations under operating leases. The Company recognizes minimum rent expense beginning when possession of the property is taken from the landlord, which normally includes a construction period prior to store opening. When a lease contains a predetermined fixed escalation of the minimum rent, the Company recognizes the related rent expense on a straight-line basis and records the difference between the recognized rental expense and the amounts payable under the lease as deferred rent. The Company also receives tenant allowances, which are recorded in deferred rent and are amortized as reductions of rent expense over the terms of the leases.
Revenue Recognition
The Company recognizes sales revenue, net of estimated returns and sales tax, at the time the customer tenders payment for and takes possession of the merchandise.
Taxes Collected
The Company reports taxes assessed by a governmental authority that are directly imposed on revenue-producing transactions (i.e., sales tax) on a net (excluded from revenue) basis.
Cost of Sales
The Company includes the cost of merchandise, warehousing and distribution costs, and certain occupancy costs in cost of sales.
Vendor Allowances
The Company receives vendor support in the form of cash payments or allowances through a variety of reimbursements such as purchase discounts, cooperative advertising, markdowns, scandowns and volume rebates. The Company has agreements with vendors setting forth the specific conditions for each allowance or payment. The Company either recognizes the allowance as a reduction of current costs or defers the payment over the period the related merchandise is sold. If the payment is a reimbursement for costs incurred, it is offset against those related costs; otherwise, it is treated as a reduction to the cost of merchandise.
Pre-Opening Costs
The Company expenses pre-opening costs for new, expanded, relocated and rebannered stores, as incurred.
Advertising Costs
The Company expenses advertising costs as they are incurred and they are included in "Selling, general and administrative expenses" on the accompanying consolidated income statements. Advertising costs, net of co-op recoveries from vendors, approximated $60.1 million, $32.5 million and $18.1 million for the years ended January 28, 2017, January 30, 2016, and January 31, 2015, respectively.
Income Taxes
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change.
The Company recognizes a financial statement benefit for a tax position if it determines that it is more likely than not that the position will be sustained upon examination.
The Company includes interest and penalties in the provision for income tax expense and income taxes payable. The Company does not provide for any penalties associated with tax contingencies unless they are considered probable of assessment.
Stock-Based Compensation
The Company recognizes expense for all share-based payments to employees based on their fair values. Total stock-based compensation expense for 2016, 2015 and 2014 was $60.3 million, $52.3 million and $37.4 million, respectively.
The Company recognizes expense related to the fair value of restricted stock units (RSUs) and stock options over the requisite service period on a straight-line basis or a shorter period based on the retirement eligibility of the grantee. The fair value of RSUs is determined using the closing price of the Company’s common stock on the date of grant. The fair value of stock option grants is estimated on the date of grant using the Black-Scholes option pricing model.
During 2016, the Company adopted Accounting Standards Update ("ASU") No. 2016-09, "Compensation-Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting." This update provides for simplification of the accounting for share-based payment transactions, including the income tax consequences and classification on the statement of cash flows. Under the update, the excess tax benefits and deficiencies that result from the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes should be recognized as income tax expense or benefit in the reporting period in which they occur. Previously, the excess tax benefits were recognized in additional paid-in capital and tax deficiencies were recognized either as an offset to accumulated excess tax benefits, if any, or in the income statement. This amendment has been adopted by the Company on a prospective basis. The update also provides that excess tax benefits should be classified along with other income tax cash flows as an operating activity on the statement of cash flows. Prior to the update, excess tax benefits were separated from other income tax cash flows and classified as a financing activity. This amendment has been adopted by the Company on a prospective transition method basis. Additionally, cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity on the statement of cash flows. Previously, no guidance was provided for cash flow classification of cash paid for tax-withholding purposes for shares withheld for tax purposes. This amendment has been adopted by the Company on a retrospective basis. As a result of the retrospective adoption of this amendment, $21.6 million and $16.0 million was reclassified in the accompanying Consolidated Statements of Cash Flows from "Changes in assets and liabilities increasing (decreasing) cash and cash equivalents" from "Other liabilities" to "Cash paid for taxes on exercises/vesting of stock-based compensation" for the years ended January 30, 2016 and January 31, 2015, respectively. Under the update, an entity can elect to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The Company has elected to account for forfeitures when they occur. All amendments of the update have been adopted for all periods beginning on or after January 31, 2016. The effect of the adoption of ASU No. 2016-09 on Retained earnings was not material.
Net Income Per Share
Basic net income per share has been computed by dividing net income by the weighted average number of shares outstanding. Diluted net income per share reflects the potential dilution that could occur assuming the inclusion of dilutive potential shares and has been computed by dividing net income by the weighted average number of shares and dilutive potential shares outstanding. Dilutive potential shares include all outstanding stock options and unvested RSUs after applying the treasury stock method.
Recent Accounting Pronouncements
In February 2016, the FASB issued ASU No. 2016-02, "Leases." This update will replace existing lease guidance in GAAP and will require lessees to recognize lease assets and lease liabilities on the balance sheet for all leases and disclose key information about leasing arrangements, such as information about variable lease payments and options to renew and terminate leases. When implemented, lessees and lessors will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The update is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently finalizing its implementation plan and evaluating the impact of the new pronouncement on its consolidated financial statements. The Company expects the adoption of this pronouncement to result in a material increase in the assets and liabilities on its consolidated balance sheets and to not have a material impact on its consolidated income statements.
In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update will replace existing revenue recognition guidance in GAAP and requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In July 2015, the FASB deferred the effective date of the new standard to interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before the original effective date for public business entities (interim and annual reporting periods beginning after December 15, 2016). ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company does not expect the adoption of this pronouncement to have a material impact on its financial statements.
