	1. Organization and Description of Business
	Sprouts Farmers Market, Inc., a Delaware corporation is the parent company of Sprouts Farmers Markets Holdings, LLC (“Intermediate Holdings”) which, through its subsidiaries, operates as a specialty retailer of natural and organic food, offering a complete shopping experience that includes fresh produce, bulk foods, vitamins and supplements, grocery, meat and seafood, bakery, dairy, frozen foods, body care and natural household items catering to consumers’ growing interest in eating and living healthier. As of December 30, 2012, the Company operated 148 stores in Arizona, California, Colorado, New Mexico, Nevada, Oklahoma, Texas and Utah. For convenience, the “Company” is used to refer collectively to Sprouts Farmers Market, Inc. and, unless the context requires otherwise, its subsidiaries. The Company’s store operations are conducted by its subsidiaries.
	Our certificate of incorporation and bylaws provide for a classified board of directors with staggered three-year terms, consisting of three classes.
	The Henry’s Transaction
	In 2002, Sprouts Farmers Markets, LLC, an Arizona limited liability company (“Sprouts Arizona”) opened the first Sprouts Farmers Market store in Chandler, Arizona. In 2011, as part of a transaction led by investment funds affiliated with, and co-investment vehicles managed by, Apollo Management VI, L.P. (the “Apollo Funds”), Sprouts Arizona combined with Henry’s Holdings LLC (“Henry’s”), which operated 35 Henry’s stores in California and eight stores in Texas under the Sun Harvest Market banner. In a series of integrated transactions referred to as the “Henry’s Transaction,” (1) Sprouts Arizona entered into a Membership Interest Purchase Agreement to acquire all of the outstanding membership interests of Henry’s from Henry’s former parent, Smart & Final (“S&F”), (2) prior to the consummation of the Henry’s Transaction, Sprouts Arizona assigned the Membership Interest Purchase Agreement, including the right to purchase Henry’s, to Intermediate Holdings (a wholly-owned subsidiary of the Company), (3) the Company (through its wholly-owned subsidiary, Intermediate Holdings) paid $274.6 million to S&F for the membership interests of Henry’s pursuant to the terms of the Membership Interest Purchase Agreement, (4) Sprouts Arizona contributed substantially all of the assets and liabilities relating to the Sprouts Farmers Market business to its wholly-owned subsidiary, SFM LLC (“SFM”), (5) Sprouts Arizona contributed SFM to Intermediate Holdings, and (6) the Company issued (a) 64,350,000 shares (representing a 58.5% ownership interest in the Company) to the Apollo Funds for a combined equity contribution of $214.0 million and (b) 45,650,000 shares (representing a 41.5% ownership interest in the Company) to Sprouts Arizona, which subsequently transferred such shares to a newly formed trust for the benefit of the members of Sprouts Arizona (referred to as the “Liquidating Trust”). The Apollo Funds are affiliates of Apollo Global Management, LLC (together with its subsidiaries, “Apollo”).
	Apollo held a controlling interest in S&F, Henry’s former parent, prior to the Henry’s Transaction and continued to hold a controlling interest in the Company afterwards. Due to Apollo’s continued controlling interest, the Henry’s Transaction resulted in Henry’s financial statements becoming the financial statements of the Company, followed immediately by the acquisition by the Company of the Sprouts Farmers Market business. As a result, the Company was determined to be the accounting acquirer, effective April 18, 2011. Accordingly, the consolidated financial statements for the period from January 3, 2011 through April 17, 2011 include the assets, liabilities, revenues and expenses directly attributable to Henry’s operations and allocations of certain corporate expenses from S&F. See Note 2 below, “Basis of Presentation,” for further discussion. Commencing on April 18, 2011, the consolidated financial statements also include the financial position, results of operations and cash flows of Sprouts Arizona.
	Sunflower Transaction
	In May 2012, the Company acquired Sunflower Farmers Markets, Inc., a Delaware corporation (the “Sunflower Transaction”) that operated 37 Sunflower Farmers Market stores (referred to as “Sunflower”), which increased the Company’s total store count to 143 and extended the Company’s footprint into New Mexico, Nevada, Oklahoma and Utah. The Company’s consolidated financial statements include the financial position, results of operations and cash flows of Sunflower commencing on May 29, 2012.
	See Note 4, “Business Combinations,” for additional information about the Henry’s and Sunflower Transactions.
	Corporate Conversion
	On July 29, 2013, Sprouts Farmers Markets, LLC, a Delaware limited liability company, converted into Sprouts Farmers Market, Inc., a Delaware corporation. As a result of the corporate conversion, the members holding interests in Class A and Class B units of Sprouts Farmers Markets, LLC became holders of common stock of Sprouts Farmers Market, Inc., and options to purchase Class B units of Sprouts Farmers Markets, LLC were converted to options to purchase shares of common stock of Sprouts Farmers Market, Inc. The conversion of units and options to purchase units was on an 11 for 1 basis. The Company refers to this transaction as the “Corporate Conversion.” All equity related disclosures, including share, per share, and option disclosures, have been revised to reflect the effects of the Corporate Conversion, including the 11 for 1 exchange.
	The purpose of the Corporate Conversion was to reorganize the corporate structure so that the top-tier entity in the corporate structure, the entity that is offering common stock to the public in this offering, is a corporation rather than a limited liability company and so that the existing investors will own the Company’s common stock rather than equity interests in a limited liability company.

	Sprouts Farmers Market, Inc., a Delaware corporation, through its subsidiaries, operates as a specialty retailer of natural and organic food, offering a complete shopping experience that includes fresh produce, bulk foods, vitamins and supplements, grocery, meat and seafood, bakery, dairy, frozen foods, body care and natural household items catering to consumers’ growing interest in eating and living healthier. The “Company” is used to refer collectively to Sprouts Farmers Market, Inc. and its subsidiaries.	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All material intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying unaudited consolidated financial statements include the accounts of the Company and its subsidiaries in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. Interim results are not necessarily indicative of results for any other interim period or for a full fiscal year. The information included in these consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto for the fiscal year ended December 30, 2012 included elsewhere in this prospectus.	The consolidated financial statements through April 17, 2011 include assets, liabilities, revenues and expenses directly attributable to the Henry’s operations and allocations of certain corporate expenses from S&F. These expenses were allocated to Henry’s on a basis that was considered to reflect fairly or reasonably the utilization of the services provided to, or the benefit obtained by, Henry’s. Historical financial statements do not reflect the debt or interest expense Henry’s might have incurred if it had been a stand-alone entity. As a result, the historical financial statements do not necessarily reflect what the financial position or results of operations would have been if Henry’s had been operated as a stand-alone entity during the periods presented, and may not be indicative of the Company’s future results of operations and financial position.
	On August 6, 2013, the Company completed its initial public offering (“IPO”) of 21,275,000 shares of common stock at a price of $18.00 per share. The Company sold 20,477,215 shares of common stock, and certain stockholders sold the remaining 797,785 shares. The Company received net proceeds from the IPO of $344.1 million, after deducting underwriting discounts and offering expenses. See Note 12, “Stockholders’ Equity” for more information.	At April 18, 2011, certain assets and liabilities, including certain property and equipment, liabilities and deferred taxes, of Henry’s were contributed from S&F, which is reflected as a net contribution through equity, totaling $14.1 million.
	The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.
	The Company reports its results of operations on a 52- or 53-week fiscal calendar ending on the Sunday closest to December 31. Fiscal years 2012 and 2013 are 52-week years. The Company reports its results of operations on a 13-week quarter, except for 53-week fiscal years.	The Company has one reportable and one operating segment. The Company’s Chief Executive Officer is the Chief Operating Decision Maker (“CODM”). The CODM bears ultimate responsibility for, and is actively engaged in, the allocation of resources and the evaluation of the Company’s operating and financial results.
	The Company has one reportable and one operating segment.	The Company categorizes its products as perishable and non-perishable. Perishable product categories include produce, meat, seafood, deli and bakery. Non-perishable product categories include grocery, vitamins and supplements, bulk items, dairy and dairy alternatives, frozen foods, beer and wine, and natural health and body care. The following is a breakdown of the Company’s perishable and non-perishable sales mix:
	The Company’s business is subject to modest seasonality. Average weekly sales fluctuate throughout the year and are typically highest in the first half of the fiscal year. Produce, which contributed 26% of the Company’s net sales for the thirty-nine weeks ended September 29, 2013, is generally more available in the first six months of the fiscal year due to the timing of peak growing seasons.
	All dollar amounts are in thousands, unless otherwise noted.
			2010		2011		2012
		Perishables		47.50%		49.20%		49.10%
		Non-Perishables		52.50%		50.80%		50.90%
		Certain prior year amounts have been revised. In 2012, the Company determined that general liability insurance should be presented as direct store expense rather than as cost of sales, buying and occupancy. The Company correctly classified $3.5 million and $1.0 million of general liability expense from cost of sales, buying and occupancy to direct store expenses in its 2011 and 2010 statements of operations, respectively.
		All dollar amounts are in thousands, unless otherwise noted.

	3. Significant Accounting Policies
	Fiscal Years
	The Company reports its results of operations on a 52- or 53-week fiscal calendar ending on the Sunday closest to December 31. Fiscal years 2010, 2011, and 2012 ended on January 2, 2011, January 1, 2012 and December 30, 2012, respectively, and included 52-weeks. Fiscal years 2010, 2011, and 2012 are referred to as 2010, 2011, and 2012.
	Significant Accounting Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities and the 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. The Company’s critical estimates included, but are not limited to: inventory valuations, lease assumptions, sublease assumptions for closed stores, self-insurance reserves, goodwill and intangible assets, impairment of long-lived assets, fair values of equity-based awards and income taxes. Actual results could differ from those estimates.
	Cash and Cash Equivalents
	The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. The Company’s cash and cash equivalents are maintained at financial institutions in the United States of America. Deposits in these financial institutions may, from time to time, exceed the Federal Deposit Insurance Corporation’s (“FDIC”) federally insured limits. All credit and debit card transactions are also classified as cash and cash equivalents. The amounts due from banks for these transactions at each reporting date were as follows:
		As Of
		January 1,			December 30,
		2012			2012
	Due from banks for debit and credit card transactions	$	13,699		$	18,092
	Accounts Receivable
	Accounts receivable generally represent billings to vendors for earned rebates and allowances and other items. When a specific account is determined uncollectible, the net recognized receivable is written off. As of December 30, 2012, the Company had recorded an allowance of $0.3 million for certain receivables. As of January 1, 2012, no allowance was recorded.
	Inventories
	Inventories consist of merchandise purchased for resale, which are stated at the lower of cost or market. The cost method is used for warehouse perishable and store perishable department inventories by assigning costs to each of these items based on a first-in, first-out (FIFO) basis (net of vendor discounts).
	Effective January 3, 2011, the Company changed its accounting policy for non-perishable inventories from the lower of cost or market using the retail inventory method (“RIM”) to the lower of cost or market using weighted average costs. The Company’s valuation of its non-perishable inventory using weighted average costs includes statistical and other estimation methods which the Company believes provide a reasonable basis to estimate its inventory values at the end of the respective periods.
	The Company believes that this new method for valuing its non-perishable products is preferable as weighted average costs results in a more accurate measure of actual inventory costs than RIM, which involves estimates of inventory costs based on an accumulation of inventory at retail price and purchase costs. The weighted average costs method of valuing inventory will also improve the comparability of the Company’s financial results with those of its competitors.
	Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 250, “Accounting Changes and Error Corrections,” requires that a change in accounting principle be reported through retrospective application of the new accounting principle to all prior periods, unless impracticable. The Company concluded retrospective application was impracticable for periods prior to 2011 because the information is not available without undue cost and effort. The Company believes the effect of the change in accounting principle as of January 3, 2011 was not material.
	The Company believes that all inventories are saleable and no allowances or reserves for shrinkage or obsolescence were recorded as of January 1, 2012 and December 30, 2012.
	Property and Equipment
	Property and equipment are stated at cost, net of accumulated depreciation and amortization. Expenditures for major additions and improvements to facilities are capitalized, while maintenance and repairs are charged to expense as incurred. When property is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations. Depreciation expense, which includes the amortization of assets recorded under capital and financing leases, is computed using the straight-line method over the estimated useful lives of the individual assets. Leasehold improvements and assets under capital and financing leases are amortized over the shorter of the lease term to which they relate, or the estimated useful life of the asset. Terms of leases used in the determination of estimated useful lives may include renewal options if the exercise of the renewal option is determined to be reasonably assured.
	The following table includes the estimated useful lives of asset classes:
	Software and used equipment		3 years
	Computer hardware		5 years
	Furniture, fixtures and equipment		7 years
	Leasehold improvements		up to 15 years
	Buildings		40 years
	Store development costs, which include costs associated with the selection and procurement of real estate sites, are also included in property and equipment. These costs are included in leasehold improvements and are amortized over the remaining lease term of the successful sites with which they are associated. Certain project costs, including general site selection costs that cannot be identified with a specific store location, are charged to direct store expenses in the accompanying consolidated statements of operations.
	Asset Retirement Obligations
	The Company’s asset retirement obligations (“ARO”) are related to the Company’s commitment to return leased facilities to the landlord in an agreed upon condition. This may require actions ranging from cleaning to removal of leasehold improvements. The obligation is recorded as a liability with an offsetting capital asset at the inception of the lease term based upon the estimated fair market value of costs to meet the commitment. The liability, included in other long-term liabilities in the consolidated balance sheets, is accreted over time to the projected future value of the obligation. The ARO asset, included in property and equipment in the consolidated balance sheets, is depreciated using the same useful life as the related property.
	A reconciliation of the ARO liability is as follows:
		As Of
		January 1,			December 30,
		2012			2012
	Beginning balance	$	580		$	1,236
	Additions for new facilities		110			132
	ARO liability from business combination		531			784
	Accretion expense		36			237
	Reduction due to lease exits		—			(11	)
	Adjustments		(21	)		(16	)
	Ending balance	$	1,236		$	2,362
	Closed Store Reserve
	The Company recognizes a reserve for future operating lease payments associated with facilities that are no longer being utilized in its current operations. The reserve is recorded based on the present value of the remaining noncancelable lease payments after the cease use date less an estimate of subtenant income. If subtenant income is expected to be higher than the lease payments, no accrual is recorded. Lease payments included in the closed store reserve are expected to be paid over the remaining terms of the respective leases. The Company’s assumptions about subtenant income are based on the Company’s experience and knowledge of the area in which the closed property is located, guidance received from local brokers and agents and existing economic conditions. Adjustments to the closed store reserve relate primarily to changes in actual or estimated subtenant income and actual lease payments from original estimates. Adjustments are made for changes in estimate in the period in which the change becomes known considering timing of new information regarding the market, subleases or other lease updates. Adjustments in the closed store reserves are recorded in “store closure and exit costs” in the consolidated statements of operations.
	Self-Insurance Reserves
	The Company uses a combination of insurance and self-insurance programs to provide reserves for potential liabilities associated with general liability, workers’ compensation and employee health benefits. Liabilities for self insurance reserves are estimated through consideration of various factors, which include historical claims experience, demographic factors, severity factors and other actuarial assumptions.
	Goodwill and Intangible Assets
	Goodwill represents the cost of acquired businesses in excess of the fair value of assets and liabilities acquired. The Company’s indefinite-lived intangible assets consist of trade names related to “Sprouts Farmers Market” and liquor licenses. The Company also holds intangible assets with finite useful lives, consisting of favorable and unfavorable leasehold interests and the “Sunflower Farmers Market” trade name.
	Goodwill is evaluated for impairment on an annual basis during the fourth fiscal quarter or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company’s impairment evaluation of goodwill consists of a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company’s qualitative assessment indicates it is more likely than not that the estimated fair value of a reporting unit exceeds its carrying value, no further analysis is required and goodwill is not impaired. Otherwise, the Company follows a two-step quantitative goodwill impairment test to determine if goodwill is impaired. The first step of the quantitative goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of the Company’s reporting unit exceeds its carrying value, no further analysis or impairment of goodwill is required. If the carrying value of the Company’s reporting unit exceeds its fair value, the fair value of the reporting unit would be allocated to the reporting unit’s assets and liabilities based on the relative fair value, with goodwill written down to its implied fair value, if necessary.
	Indefinite-lived assets are evaluated for impairment on an annual basis during the fourth fiscal quarter or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company’s impairment evaluation for its indefinite-lived intangible assets consists of a qualitative assessment similar to that for goodwill. If the Company’s qualitative assessment indicates it is more likely than not that the estimated fair value of an indefinite-lived intangible asset exceeds its carrying value, no further analysis is required and the asset is not impaired. Otherwise, the Company compares the estimated fair value of the asset to its carrying amount with an impairment loss recognized for the amount, if any, by which carrying value exceeds estimated fair value.
	The Company can elect to bypass the qualitative assessments approach for goodwill and indefinite-lived intangible assets and proceed directly to the quantitative assessments for goodwill or any indefinite-lived intangible assets in any period. The Company can resume the qualitative assessment approach in future periods.
	The Company has determined its business consists of a single reporting unit. When applying the quantitative test, the Company determines the fair value of its reporting unit using the income approach methodology of valuation that includes the discounted cash flow method as well as other generally accepted valuation methodologies.
	The Company completed its goodwill and indefinite-lived intangible asset impairment evaluations as of the first day of the fourth quarter and concluded during 2010, 2011 and 2012 that there was no impairment. The Company also concluded that events and circumstances continued to support classifying its indefinite-lived intangible assets as such. See Note 8, “Intangible Assets” and Note 9, “Goodwill” for further discussion.
	Prior to the Henry’s Transaction, the trade names related to “Henry’s Farmers Markets” were accounted for as finite-lived intangible assets and amortized on a straight-line basis over an estimated useful life of 20 years. As a result of the rebranding of the “Henry’s Farmers Markets” locations as “Sprouts Farmers Market” locations following the Henry’s Transaction, the estimated remaining useful lives of these trade names were re-evaluated and amortization was accelerated through the end of their respective useful life in fiscal 2011, when it was subsequently written-off. See Note 8, “Intangible Assets” for further discussion. The trade name related to “Sunflower Farmers Market” meets the definition of a defensive intangible asset and is amortized on a straight line basis over an estimated useful life of 10 years from the date of its acquisition by the Company. Favorable and unfavorable leasehold interests are amortized on a straight-line basis over the lease term.
	Impairment of Long-Lived Assets
	The Company assesses its long-lived assets, including property and equipment and finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. The Company groups and evaluates long-lived assets for impairment at the individual store level, which is the lowest level at which independent identifiable cash flows are available. Factors which may indicate potential impairment include a significant underperformance relative to the historical or projected future operating results of the store or a significant negative industry or economic trend. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by that asset. If impairment is indicated, a loss is recognized for any excess of the carrying value over the estimated fair value of the asset group. The fair value is estimated based on the discounted future cash flows or comparable market values, if available. The Company did not record any impairment loss during 2010, 2011 or 2012.
	Deferred Financing Costs
	The Company capitalizes certain fees and costs incurred in connection with the issuance of debt. Deferred financing costs are amortized to interest expense over the term of the debt using the effective interest method. For the Revolving Credit Facility, deferred financing costs are amortized on a straight line basis over the term of the facility. Upon prepayment, redemption or conversion of debt, the Company accelerates the recognition of an appropriate amount of financing costs as additional interest expense. The current and noncurrent portions of deferred financing costs are included in prepaid expenses and other current assets and other assets, respectively, in the consolidated balance sheets.
	Operating Leases
	The Company leases stores, warehouse facilities and administrative offices under operating leases.
	Incentives received from lessors are deferred and recorded as a reduction of rental expense over the lease term using the straight-line method. The current portion of unamortized lease incentives is included in other accrued liabilities and the noncurrent portion is included in other long-term liabilities in the accompanying consolidated balance sheets.
	Store lease agreements generally include rent abatements and rent escalation provisions and may include contingent rent provisions based on a percentage of sales in excess of specified levels. The Company recognizes escalations of minimum rents and/or abatements as deferred rent and amortizes these balances on a straight-line basis over the term of the lease.
	For lease agreements that require the payment of contingent rents based on a percentage of sales above stipulated minimums, the Company begins accruing an estimate for contingent rent when it is determined that it is probable the specified levels of sales in excess of the stipulated minimums will be reached during the year.
	Financing Lease Obligations
The Company has recorded financing lease obligations for 22 and 31 store building leases as of January 1, 2012 and December 30, 2012, respectively. In each case, the Company was deemed to be the owner during the construction period under lease accounting guidance. Further, each lease contains provisions indicating continuing involvement with the property at the end of the construction period which include either an affiliate guaranty or contingent collateral. As a result, in accordance with applicable accounting guidance, buildings and related assets subject to the leases are reflected on the Company’s balance sheets and depreciated over their remaining useful lives. The present value of the lease payments associated with these buildings is recorded as financing lease obligations.
Monthly lease payments are allocated between the land element of the lease (which is accounted for as an operating lease) and the financing obligation. The financing obligation is amortized using the effective interest method and the interest rate is determined in accordance with the requirements of sale-leaseback accounting. Lease payments less the portion allocated to the land element of the lease and that portion considered to be interest expense decrease the financing liability. At the end of the initial lease term, should the Company decide not to renew the lease, the net book value of the asset and the corresponding financing obligation would be reversed.
The outflows from the construction of the buildings are classified as investing activities, and the outflows associated with the financing obligations principal payments and inflows from the associated financing proceeds are classified as financing activities in the accompanying consolidated statements of cash flows.
Fair Value Measurements
The Company records its financial assets and liabilities in accordance with the framework for measuring fair value in accordance with GAAP. This framework establishes a fair value hierarchy that prioritizes the inputs used to measure fair value:
Level 1: Quoted prices for identical instruments in active markets.
Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
Fair value measurements of nonfinancial assets and nonfinancial liabilities are primarily used in the impairment analysis of goodwill, intangible assets, long-lived assets and in the valuation of store closure and exit costs.
The determination of fair values of certain tangible and intangible assets for purposes of our goodwill impairment evaluation as described above was based upon level 3 inputs. Closed store reserves are recorded at net present value to approximate fair value which is classified as Level 3 in the hierarchy. The estimated fair value of the closed store reserve is calculated based on the present value of the remaining lease payments and other charges using a weighted average cost of capital, reduced by estimated sublease rentals. The weighted average cost of capital was estimated using information from comparable companies and management’s judgment related to the risk associated with the operations of the stores.
Cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued salaries and benefits and other accrued liabilities approximate fair value because of the short maturity of those instruments. Based on comparable open market transactions of the Term Loan (as defined in Note 13, “Long-Term Debt”), the fair value of the long-term debt, including current maturities, approximates carrying value as of January 1, 2012 and December 30, 2012. The carrying amount of the Senior Subordinated Promissory Notes (as defined in Note 13, “Long-Term Debt”) approximates fair value as its terms are consistent with current market rates as of December 30, 2012. The Company’s estimates of the fair value of long-term debt (including current maturities) and the Senior Subordinated Promissory Notes were classified as Level 2 in the fair value hierarchy.
Business Combinations
Business combinations are accounted for using the acquisition method of accounting, which requires that the purchase price paid for an acquisition be allocated to the assets and liabilities acquired based on their estimated fair values as of the effective date of the acquisition, with the excess of the purchase price over the net assets being recorded as goodwill. Acquisition-related costs are considered separate transactions and are expensed as incurred. Acquisition-related costs are classified as selling, general and administrative expenses and consist of costs associated with the Henry’s Transaction in 2011 and costs associated with the Sunflower Transaction in 2012, as follows:
	Year Ended
	January 1,			December 30,
	2012			2012
Acquisition-related costs	$	5,900		$	3,229
See Note 4, “Business Combinations” for further discussion.
Equity-Based Compensation
The Company measures equity-based compensation cost at the grant date based on the fair value of the award and recognizes equity-based compensation cost as expense over the vesting period. As equity-based compensation expense recognized in the consolidated statements of operations is based on awards ultimately expected to vest, the amount of expense has been reduced for estimated forfeitures and trued up for actual forfeitures. The Company’s forfeiture rate is estimated primarily based on historical data. The actual forfeiture rate could differ from these estimates. The Company uses the Black-Scholes option-pricing model to determine the grant date fair value for each option grant. The Black-Scholes option-pricing model requires extensive use of subjective assumptions. See Note 24, “Equity-Based Compensation” for a discussion of assumptions used in the calculation of fair values. Application of alternative assumptions could produce different estimates of the fair value of equity-based compensation and, consequently, the related amounts recognized in the accompanying consolidated statements of operations. The Company recognizes compensation cost for time-based awards on a straight-line basis and for performance-based awards on the graded-vesting method over the vesting period of the awards.
Revenue Recognition
Revenue is recognized at the point of sale. Discounts provided to customers at the time of sale are recognized as a reduction in sales as the discounted products are sold. Sales taxes are not included in revenue. Proceeds from the sale of gift cards are recorded as a liability at the time of sale, and recognized as sales when they are redeemed by the customer. The Company has not applied a gift card breakage rate.
Licensing fees are generated from license agreements related to two former Henry’s stores.
Cost of Sales, Buying and Occupancy
Cost of sales includes the cost of inventory sold during the period, including the direct costs of purchased merchandise (net of discounts and allowances), distribution and supply chain costs, buying costs and supplies. Occupancy costs include store rental, property taxes, utilities, common area maintenance, amortization of favorable or unfavorable leasehold interests and property insurance. The Company recognizes vendor allowances and merchandise volume related rebate allowances as a reduction of inventories during the period when earned and reflects the allowances as a component of cost of sales, buying and occupancy as the inventory is sold.
Our largest supplier accounted for approximately 17% of total purchases, expressed as a percentage of our cost of sales, buying and occupancy goods, during 2012.
Direct Store Expenses
Direct store expenses consist of store-level expenses such as salaries and benefits, related equity-based compensation, supplies, depreciation and amortization for buildings and store leasehold improvements, equipment and other store specific costs.
Selling, General and Administrative Expenses
Selling, general and administrative expenses primarily consist of salaries and benefits costs, related equity-based compensation, advertising, acquisition-related costs and corporate overhead.
The Company charges third-parties to place advertisements in the Company’s in-store guide and newspaper circulars. The Company records consideration received from vendors in connection with cooperative advertising programs as a reduction to advertising costs when the allowance represents a reimbursement of a specific incremental and identifiable cost. Advertising costs are expensed as incurred. Advertising expense was as follows:
	Year Ended
	January 2,			January 1,			December 30,
	2011			2012			2012
Advertising expense	$	9,342		$	22,344		$	29,238
Vendor rebates		(1,650	)		(5,745	)		(9,905	)
Advertising expense, net of rebates	$	7,692		$	16,599		$	19,333
Store Pre-Opening Costs
Store pre-opening costs include rent expense during construction of new stores and costs related to new store openings, including costs associated with hiring and training personnel and other miscellaneous costs. Store pre-opening costs are expensed as incurred.
Loss on Extinguishment of Debt
The Company recorded a $1.0 million loss on extinguishment of debt in 2012 as a result of the renegotiation of a store lease that was classified as a financing lease obligation.
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 the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. 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. The Company’s deferred tax assets are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. Realization of the deferred tax assets is principally dependent upon achievement of projected future taxable income offset by deferred tax liabilities. Changes in recognition or measurement are reflected in the period in which the judgment occurs. Since becoming a taxable corporation in April 2011, the Company has not recorded any valuation allowances to date on the Company’s deferred income tax assets.
The Company recognizes the effect of uncertain 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 records interest and penalties related to unrecognized tax benefits as part of income tax expense.
From a tax perspective, in April 2011, the Company acquired Henry’s. Until April 18, 2011, Henry’s was not a separate tax-paying entity. Henry’s was included in the S&F consolidated federal and certain state income tax groups for income tax reporting purposes. For the period through April 17, 2011, the consolidated financial statements have been prepared on the basis as if Henry’s prepared its tax returns and accounted for income taxes on a separate-company basis. As a result of the Henry’s Transaction, for tax purposes, Henry’s was acquired in a taxable asset acquisition. The purchase price was allocated to all identifiable assets with the residual assigned to tax deductible goodwill. The resulting basis differences between the new tax values and historical amounts resulted in a deferred tax asset of $47.6 million being recorded through membership equity. See Note 18, “Income Taxes” for a discussion of the tax deductibility of goodwill.
In May 2012, the Company completed the acquisition of a 100% ownership interest in Sunflower. The acquisition was structured to be a tax-free reorganization. The tax basis of the property acquired in reorganization is equal to the basis in the property recorded by Sunflower just prior to the acquisition. The resulting basis difference between the historical tax amounts and the fair values resulted in net deferred tax assets of $1.9 million being recorded through goodwill.
Net Income (Loss) per Share
Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the fiscal period.
Diluted net income (loss) per share is based on the weighted average number of shares outstanding, plus, where applicable, shares that would have been outstanding related to dilutive options.
Comprehensive Income (Loss)
Comprehensive income (loss) equals net income (loss) for all periods presented.
Recently Issued Accounting Pronouncements
In June 2011, the FASB issued ASU 2011-05 “Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, the FASB issued ASU 2011-12 “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”). ASU 2011-12 deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company adopted this guidance on January 2, 2012 and such adoption did not have a significant effect on the Company’s consolidated financial statements as it has no components of other comprehensive income and is therefore not required to present a statement of comprehensive income.
In May 2011, the FASB issued Accounting Standards Update (“ASU”) No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends ASC 820, “Fair Value Measurement.” The amended guidance changes the wording used to describe many requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. Additionally, the amendments clarify the FASB’s intent about the application of existing fair value measurement requirements. The guidance provided in ASU No. 2011-04 is effective for interim and annual periods beginning after December 15, 2011 and is applied prospectively. The Company adopted this guidance on January 2, 2012. The adoption of the guidance did not have a significant effect on the Company’s consolidated financial statements.
In September 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment” (“ASU 2011-08”), which amends ASC 350, “Intangibles-Goodwill and Other”. The objective of the amended guidance is to simplify how entities test goodwill for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC 350. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The guidance provided in ASU 2011-08 is effective for fiscal years beginning after December 15, 2011. The Company adopted this guidance on January 2, 2012. The adoption of this guidance resulted in a change in how the Company performed its goodwill impairment assessment; however, it did not have a significant effect on the Company’s consolidated financial statements.
In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which amends ASC 350, “Intangibles-Goodwill and Other”. The amendment guidance simplifies how entities test for impairment of indefinite-lived intangible assets. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount as a basis for determining if performing a quantitative test is necessary. The amendments do not change the measurement of impairment losses. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted and the Company has adopted the guidance as of the first day of the fourth quarter of 2012. The adoption of this guidance resulted in a change in how the Company performed its indefinite-lived intangible asset impairment assessment; however, it did not have a significant effect on its consolidated financial statements.

	In May 2012, the Company acquired Sunflower Farmers Markets, Inc., a Delaware corporation (the “Sunflower Transaction”), that operated 37 Sunflower Farmers Market stores (“Sunflower”), which increased the Company’s total store count to 143 and extended the Company’s footprint into New Mexico, Nevada, Oklahoma and Utah. The Company’s consolidated financial statements include the financial position, results of operations and cash flows of Sunflower commencing on May 29, 2012.			As discussed in Note 1, “Organization and Description of Business” the Company completed the Henry’s and Sunflower Transactions in April 2011 and May 2012, respectively. Each of these transactions were accounted for as a business combination. The primary reasons for these transactions were to build a larger portfolio of stores under the Sprouts Farmers Market banner and to derive synergies from the combined operations of the companies.
	Unaudited supplemental pro forma information			In a business combination, the purchase price is allocated to assets acquired and liabilities assumed based on their fair values, with any excess of purchase price over fair value recognized as goodwill. In addition to reviews of acquired company balance sheets, the Company reviews supply contracts, leases, financial instruments, employment agreements and other significant agreements to identify potential assets or liabilities that require recognition in connection with the application of acquisition accounting under ASC 805. Intangible assets are recognized apart from goodwill when the asset arises from contractual or other legal rights, or is separable from the acquired entity such that it may be sold, transferred, licensed, rented or exchanged either on a standalone basis or in combination with a related contract, asset or liability.
	The following table presents unaudited supplemental pro forma consolidated results of operations information for the thirty-nine weeks ended September 30, 2012. The unaudited supplemental pro forma consolidated results of operations information gives effect to certain adjustments, including depreciation and amortization of the assets acquired and liabilities assumed based on their estimated fair values and changes in interest expense resulting from changes in consolidated debt, as if the Sunflower Transaction occurred at the beginning of 2011:			Henry’s Transaction
				Pursuant to the terms of the agreements governing the Henry’s Transaction, on the April 18, 2011:
		Thirty-Nine  Weeks			Ÿ		The Company (through its wholly-owned subsidiary, Intermediate Holdings) purchased all of the outstanding membership interests of Henry’s for a cash payment of $274.6 million;
		Ended
		September 30,			Ÿ		Sprouts Arizona contributed substantially all of its assets and liabilities to SFM, LLC and the former owners of Sprouts Arizona received 45,650,000 shares (representing a 41.5% ownership interest in the Company), which were subsequently transferred to the Liquidating Trust;
		2012
	Net sales	$	1,512,022		Ÿ		Cash distribution of $199.1 million was paid to the Liquidating Trust; and
	Net income	$	16,969
	The unaudited supplemental pro forma consolidated results of operations information is provided for illustrative purposes only and does not purport to present what the actual results of operations would have been had the Sunflower Transaction actually occurred on the date indicated, nor does it purport to represent results of operations for any future period. The unaudited supplemental pro forma information includes certain non-recurring costs incurred as a result of the Sunflower Transaction, such as acquisition-related costs and expenses due to change in control. The information does not reflect any cost savings or other benefits that may be obtained through synergies among the operations of the Company, except to the extent realized in 2012.				Ÿ		Sprouts Arizona pre-combination debt was extinguished and preferred equity was redeemed.
				The $274.6 million payment was accounted for as a distribution to S&F in the Company’s consolidated statements of stockholders’ equity.
				Collectively, the consummation of the Henry’s Transaction was financed through issuance of debt by Intermediate Holdings (see Note 13, “Long-Term Debt”), and the issuance of 64,350,000 shares (representing a 58.5% ownership in the Company) to the Apollo Funds for a combined contribution of $214.0 million.
				Consideration transferred was determined as follows:
						Fair Value of
						Consideration
						Transferred
				Cash paid to Liquidating Trust		$	199,146
				Fair value of Company’s shares issued			146,137
				Cash paid to extinguish Sprouts Arizona debt (net of cash acquired)			32,085
				Cash paid to redeem Sprouts Arizona preferred membership units			1,680
				Total purchase price		$	379,048
				The fair value of our shares issued in connection with the Henry’s Transaction was determined to be $3.33 per share, the fair value as determined as of the acquisition measurement date, which is the date the Henry’s Transaction closed.
				The Company’s allocation of purchase price in the Henry’s Transaction was as follows:
				Net assets acquired:
				Inventory		$	35,105
				Other current assets			4,092
				Property and equipment			130,219
				Intangible assets			188,613
				Other assets			1,412
				Liabilities assumed:
				Current liabilities			(36,519	)
				Capital lease obligations			(3,990	)
				Financing lease obligations			(63,162	)
				Other long-term liabilities			(13,570	)
				Deferred taxes			(7,756	)
				Goodwill			144,604
				Total purchase price		$	379,048
				Goodwill was attributed to the assembled workforce of Sprouts Arizona and synergies expected to be achieved from the combined operations of Henry’s and Sprouts Arizona, primarily related to buying and distribution costs, economies of scale for certain direct store expenses and savings on marketing-related selling costs and corporate overhead. Goodwill recorded in the Henry’s Transaction is expected to be deductible for tax purposes.
				Identifiable intangible assets acquired consist of the following (in thousands):
				Trade names (indefinite-lived)		$	182,937
				Liquor licenses (indefinite-lived)			247
				Favorable leasehold interests (13.5 years weighted average useful life)			5,429
				Total intangible assets		$	188,613
				Sales and net loss of SFM totaling $556.0 million and $44.5 million, respectively, are included in the consolidated results of operations for the year ended January 1, 2012.
				Sunflower Transaction
				As described in Note 1, “Organization and Description of Business,” effective May 29, 2012 the Company acquired all of the outstanding common and preferred stock of Sunflower in a transaction financed through issuance of debt by Intermediate Holdings (see Note 13, “Long-Term Debt), and the issuance of 14,898,136 shares. Consideration transferred was determined as follows:
						Fair Value of
						Consideration
						Transferred
				Cash paid to Sunflower		$	108,517
				Fair value of Company’s shares issued			89,605
				Cash paid to extinguish Sunflower’s debt, net of cash acquired			21,358
				Total purchase price		$	219,480
				The fair value of our shares issued in connection with the Sunflower Transaction was determined to be $6.01 per share, the fair value as determined as of the acquisition measurement date, which is the date the Sunflower Transaction closed.
				The Company’s allocation of purchase price in the Sunflower Transaction is as follows:
				Net assets acquired:
				Inventory		$	33,321
				Deferred tax asset			2,308
				Other current assets			3,859
				Property and equipment			67,347
				Intangible assets			7,416
			Other assets			1,246
			Liabilities assumed:
			Current liabilities			(36,534	)
			Financing lease obligations			(22,616	)
			Deferred tax liability			(412	)
			Other long-term liabilities			(6,103	)
			Goodwill			169,648
			Total purchase price		$	219,480
			Goodwill was attributed to the assembled workforce of Sunflower and synergies expected to be achieved from the combined operations of the Company and Sunflower, primarily related to buying and distribution costs, economies of scale for certain direct store expenses and savings on marketing-related selling costs and corporate overhead. Goodwill recorded in the Sunflower Transaction is not expected to be deductible for tax purposes.
			Identifiable intangible assets consist of the following:
			Trade name (10 year useful life)		$	1,800
			Liquor licenses (indefinite-lived)			1,070
			Favorable leasehold interests (12.3 years weighted average useful life)			4,546
			Total intangible assets		$	7,416
			Sales and net income of Sunflower totaling $297.8 million and $8.6 million respectively are included in the consolidated results of operations for the year ended December 30, 2012.
			Valuations
			The Company engaged an independent valuation firm to assist management with the valuations of acquired inventory, personal property, real estate, favorable and unfavorable leasehold interests and intangible assets for the Henry’s and Sunflower Transactions. Acquired inventory was recorded at net realizable value, with significant estimates relating to the time expected to dispose of inventory, disposal costs and commensurate profit. Personal property, consisting primarily of leasehold improvements and furniture, fixtures and equipment, were valued using the cost method, which requires significant estimates related to replacement costs of acquired personal property, as well as estimates of physical deterioration. Real estate was valued through a combination of income and market approaches and significant estimates underlying these valuations include market comparable pricing and capitalization rates, which the independent valuation firm assisted management in determining.
			The value of the Sprouts trade name and trademarks was determined using an income approach, utilizing a relief from royalty method in conjunction with a profit split methodology. The relief from royalty method estimates the theoretical royalty savings resulting from ownership of the Sprouts trade name and trademarks. Significant estimates used in this valuation method include discount rate, royalty rates, growth rates and sales projections. The discount rate used was the Company’s weighted average cost of capital, the royalty rate was a base rate determined by reference to comparable market royalty rate agreements and growth rates and projected sales were determined using forecasts prepared by management.
			The Sunflower trade name was accounted for as a “defensive intangible asset” with an estimated useful life of 10 years from the date of the Sunflower Transaction. Acquired liquor licenses were valued using a cost approach.
			Unaudited supplemental pro forma information
			The following table presents unaudited supplemental pro forma consolidated results of operations information for 2010, 2011 and 2012. The unaudited supplemental pro forma consolidated results of operations information gives effect to certain adjustments, including depreciation and amortization of the assets acquired and liabilities assumed based on their estimated fair values and changes in interest expense resulting from changes in consolidated debt, as if the Henry’s Transaction occurred at the beginning of 2010 and the Sunflower Transaction occurred at the beginning of 2011:

			The unaudited supplemental pro forma consolidated results of operations information is provided for illustrative purposes only and does not purport to present what the actual results of operations would have been had the Henry’s Transaction and Sunflower Transaction actually occurred on the dates indicated, nor does it purport to represent results of operations for any future period. The unaudited supplemental pro forma information includes certain non-recurring costs incurred as a result of the Transactions, such as acquisition-related costs and expenses due to change in control and Sprouts Arizona manager termination fees. The information does not reflect any cost savings or other benefits that may be obtained through synergies among the operations of the Company, except to the extent realized in 2011 and 2012.

	a)	In connection with the Henry’s Transaction, the Henry’s stores were rebranded as Sprouts Farmers Market. The estimated useful lives related to the Henry’s trade names and capitalized software were reevaluated and it was determined that amortization of these assets should be accelerated over their estimated remaining useful lives through January 1, 2012. The accelerated amortization was recorded in the statements of operations as Amortization of Henry’s trade names and capitalized software and reflected in the additions column of this table. The net book values of these assets were zero as of January 1, 2012 which were written off and are reflected in the adjustment column in this table.
	b)	Certain assets and liabilities were distributed to S&F through equity, see Note 4, “Business Combinations” for more detail.
	c)	The Company sold two liquor licenses obtained in the Sunflower Transaction.
	Amortization expense was $3.9 million, $32.7 million and $1.1 million for 2010, 2011 and 2012, respectively.
	Amortization expense for 2011 includes $32.2 million of amortization expense for the amortization of the Henry’s trade name and capitalized software including acceleration.
	Future amortization associated with the net carrying amount of finite-lived intangible assets is estimated to be as follows:

Debt Maturities

Senior Secured Credit Facilities

Aggregate annual maturities on long-term debt as of December 30, 2012 for each of the years are as follows:

April 2013 Refinancing

On April 23, 2013, the Company’s subsidiary, Sprouts Farmers Markets Holdings, LLC (“Intermediate Holdings”), as borrower, refinanced (the “April 2013 Refinancing”) the Former Revolving Credit Facility and the Former Term Loan (each, as defined below), by entering into a new credit facility (the “Credit Facility”). The Credit Facility provides for a $700.0 million term loan (the “Term Loan”) and a $60.0 million senior secured revolving credit facility (the “Revolving Credit Facility”).

The proceeds of the Term Loan were used to repay in full the outstanding Former Term Loan balance of $403.1 million. Such repayment resulted in an $8.2 million loss on extinguishment of debt due to the write-off of deferred financing costs and original issue discount. No amounts were outstanding under the Former Revolving Credit Facility. The remaining proceeds from the Term Loan, together with cash on hand, were used to make a $282.0 million distribution to the Company’s equity holders, to make payments of $13.9 million to vested option holders and to pay transaction fees and expenses related to the refinancing.

2013

$

4,100

The terms of the Credit Facility allow the Company, subject to certain conditions, to increase the amount of the term loans and revolving commitments thereunder by an aggregate incremental amount of up to $160.0 million, plus an additional amount, so long as after giving effect to such increase, (i) in the case of incremental loans that rank pari passu with the initial term loans, the net first lien leverage ratio does not exceed 4.00 to 1.00, and (ii) in the case of incremental loans that rank junior to the initial Term Loan, the total leverage ratio does not exceed 5.25 to 1.00.

2014

4,100

Guarantees

2015

5,125

Obligations under the Credit Facility are guaranteed by the Company and all of its current and future wholly owned material domestic subsidiaries. Borrowings under the Credit Facility are secured by (i) a pledge by Sprouts of its equity interests in Intermediate Holdings and (ii) first-priority liens on substantially all assets of Intermediate Holdings and the subsidiary guarantors, in each case, subject to permitted liens and certain exceptions.

2016

Term Loan and Partial Repayment in IPO

2017

4,100

On August 6, 2013, the Company used $340.0 million of the net proceeds from its IPO to make a partial repayment of the Term Loan. Such repayment resulted in a $9.0 million loss on extinguishment of debt due to the write-off of deferred financing costs and original issue discount for the portion of the debt repaid. This loss on extinguishment of debt is reflected in the Company’s statement of operations for the thirty-nine weeks ended September 29, 2013. As of September 29, 2013, the outstanding balance of the Term Loan was $351.8 million, net of issue discount of $8.2 million. Financing fees and issue discount are being amortized to interest expense over the term of the Term Loan.

Thereafter

418,575

Interest and Applicable Margin

All amounts outstanding under the Credit Facility will bear interest, at the Company’s option, at a rate per annum equal to LIBOR (with a 1.00% floor with respect to Eurodollar borrowings under the Term Loan), adjusted for statutory reserves, plus a margin equal to 3.00%, or an alternate base rate, plus a margin equal to 2.00%, as set forth in the Credit Facility. These interest margins were reduced to their current levels (from 3.50% and 2.50%, respectively) effective August 2, 2013 as a result of (i) the consummation of the Company’s IPO, and (ii) the Company achieving a reduction in the net first lien leverage ratio to less than or equal to 2.75 to 1.00.

Gross principal

440,100

Payments and Prepayments

Less: discount

(13,556

)

The Term Loan will mature in April 2020 and will amortize at a rate per annum, in four equal quarterly installments, in an aggregate amount equal to 1.00% of the original principal balance, with the balance due on the maturity date.

Subject to exceptions set forth therein, the Credit Facility requires mandatory prepayments in amounts equal to (i) 50% (reduced to 25% if net first lien leverage is less than 3.00 to 1.00 but greater than 2.50 to 1.00 and 0% if net first lien leverage is less than 2.50 to 1.00) of excess cash flow (as defined in the Credit Facility) at the end of each fiscal year, (ii) 100% of the net cash proceeds from certain non-ordinary course asset sales by the Company or any subsidiary guarantor (subject to certain exceptions and reinvestment provisions) and (iii) 100% of the net cash proceeds from the issuance or incurrence of debt by the Company or any of its subsidiaries not permitted under the Credit Facility.

Total debt at December 30, 2012

$

426,544

Voluntary prepayments of borrowings under the Credit Facility are permitted at any time, in agreed-upon minimum principal amounts. There is a prepayment fee equal to 1.00% of the principal amount of the Term Loan under the Credit Facility optionally prepaid in connection with any “repricing transaction” on or prior to April 23, 2014, the first anniversary of the closing date. Prepayments made thereafter will not be subject to premium or penalty (except LIBOR breakage costs, if applicable).

Revolving Credit Facility

Senior Secured Credit Facilities

The Credit Facility includes a $60.0 million Revolving Credit Facility which matures in April 2018. The Revolving Credit Facility includes letter of credit and $5.0 million swingline loan subfacilities. Letters of credit issued under the facility reduce the borrowing capacity on the total facility. There are no amounts outstanding on the Revolving Credit Facility at September 29, 2013. Letters of credit totaling $8.0 million have been issued as of September 29, 2013 primarily to support the Company’s insurance programs. Amounts available under the Revolving Credit Facility at September 29, 2013 totaled $52.0 million.

On April 18, 2011, the Company entered into senior secured credit facilities (“Senior Secured Credit Facilities”) with Jefferies Finance LLC, as administrative agent and collateral agent, JPMorgan Chase Bank, N.A., as letter of credit issuer, and various lenders. The borrower under such senior secured credit facilities is the Company’s wholly-owned subsidiary, Intermediate Holdings (the “borrower”). During April 2012, the Company amended the senior secured credit facilities as described below.

Interest terms on the Revolving Credit Facility are the same as the Term Loan.

The Senior Secured Credit Facilities provide for a $50.0 million revolving credit facility (“Revolving Credit Facility”), which includes a letter of credit subfacility (up to the unused amount of the Revolving Credit Facility) and a $5.0 million swingline loan subfacility. The Revolving Credit Facility maturity date is April 18, 2016.

The Company capitalized debt issuance costs of $1.1 million related to the Revolving Credit Facility, which are being amortized to interest expense over the term of the Revolving Credit Facility.

The Company uses its Revolving Credit Facility for general corporate purposes, including permitted business acquisitions and, in the case of letters of credit, for the back-up or replacement of existing letters of credit.

Under the terms of the Credit Facility, the Company is obligated to pay a commitment fee on the available unused amount of the Revolving Credit Facility commitments equal to 0.50% per annum.

The Senior Secured Credit Facilities also provide for a $310.0 million term loan (“Term Loan”) facility which currently matures on April 18, 2018. The Company has used the Term Loan to effect certain acquisitions.

Covenants

The Company’s Senior Secured Credit Facilities also (i) contain incremental facility provisions that permit the Company, without the consent of the existing lenders, to incur up to $100.0 million of incremental term and/or revolving commitments with pricing, amortization and final maturity dates which are the same or different from those in existence for the existing Revolving Credit Facility or Term Loan, (ii) permit the Company, without the consent of the existing lenders, to incur additional tranches of Term Loan and/or additional revolving facilities to refinance the existing Revolving Credit Facility and/or Term Loan and (iii) permit the Company, to solicit, without the consent of the existing lenders, consent of term lenders under any term facilities to extend the scheduled maturity of such facilities, subject to certain requirements.

The Credit Facility contains financial, affirmative and negative covenants. The negative covenants include, among other things, limitations on the Company’s ability to:

Ÿ

merge, consolidate or enter into acquisitions;

Interest is payable at the end of each quarter in the case of the adjusted dollar base rate option. In the case of the LIBOR option, whereby the contract period may be equal to one, two, three or six months from the date of initial borrowing, interest is payable on the last day of each contract period.

	General Liability and Workers’ Compensation
	The Company carries insurance policies for general liability and workers’ compensation to minimize the risk of loss due to accident, injury and commercial liability claims resulting from its operations, and to comply with certain legal and contractual requirements.
	The Company retains certain levels of exposure in its self-insurance programs and purchases coverage from third-party insurers for exposures in excess of those levels. In addition to expensing premiums and other costs relating to excess coverage, the Company establishes reserves for claims, both reported and incurred but not reported (“IBNR”). IBNR claims are estimated using historical claim information, demographic factors, severity factors and other actuarial assumptions. See Note 12, “Other Accrued Liabilities,” and Note 14, “Other Long-Term Liabilities” for amounts recorded for general liability and workers’ compensation liabilities.
	Prior to the Henry’s transaction, S&F purchased third-party insurance for general liability under which Henry’s was covered.
	Medical
	The Company is self-insured for medical claims up to certain stop-loss limits. Such costs are accrued based on known claims and an estimate of IBNR claims. IBNR claims are estimated using historical claim information, demographic factors, severity factors and other actuarial assumptions. As of December 30, 2012, the Company had recorded a receivable for stop-loss payments from its medical insurance carriers of $1.3 million relating to the portion of the recorded liability that is expected to be recovered through those payments.
	The estimated accruals for the self-insurance liabilities could be significantly affected if future occurrences and claims differ from historical trends.

	16. Defined Contribution Plan
	The Company maintains the Sprouts Farmers Markets, LLC Employee 401(k) Savings Plan (the “Plan”), which is a defined contribution plan covering all eligible employees. Under the provisions of the Plan, participants may direct the Company to defer a portion of their compensation to the Plan, subject to the Internal Revenue Code limitations. The Company provides for an employer matching contribution equal to 50% of each dollar contributed by the participants up to 6% of their eligible compensation.
	During 2011, prior to the Henry’s Transaction, Henry’s employees participated in the Markets Retirement 401(k) Savings Plan (“Henry’s 401(k) Plan”), which allowed participants to contribute up to 95% of their eligible compensation, subject to certain maximums. In 2011 the Company matched 50% of each dollar contributed up to the first 4% of the participant’s eligible compensation and then matched 25% of each dollar contributed up to an additional 2% of the participant’s eligible compensation.
	In conjunction with the Henry’s Transaction, the Company acquired the Henry’s 401(k) Plan, which was merged into the plan effective January 1, 2012. Participants in the Henry’s 401(k) Plan are eligible for the same employer matching contribution as those under the Plan effective January 1, 2012.
	Total expense recorded for the matching under all defined contribution plans:

	The Company’s effective tax rate for the thirty-nine weeks ended September 30, 2012 and September 29, 2013 was 44.2% and 39.3%, respectively. The decrease in the effective tax rate was primarily the result of nondeductible transaction costs for the Sunflower Transaction for the thirty-nine weeks ended September 30, 2012.	Through the April 17, 2011, the Company’s consolidated financial statements reflect a charge for federal and state income taxes as if Henry’s had been subject to tax on a separate company basis during the periods presented. Subsequent to April 17, 2011, the Company’s (provision) benefit for income taxes is based on the new tax return filing group.
	In September 2013 the Internal Revenue Service issued final regulations related to tangible property, which govern when a taxpayer must capitalize or deduct expenses for acquiring, maintaining, repairing and replacing tangible property. The regulations are effective for tax years beginning January 1, 2014, however early adoption is permitted. The Company has analyzed the impacts of the tangible property regulations, and has determined it is in compliance with the regulations. The adoption of the regulations will not have a significant effect on the Company’s consolidated financial statements.	During the period from April 17, 2011 until the corporate conversion, the Company had elected to be taxed as a corporation for income tax purposes.
		Income Tax (Provision) Benefit
		Income tax (provision) benefit consists of the following:
			Year Ended
			January 2,			January 1,			December 30,
			2011			2012			2012
		U.S. Federal—current	$	(153	)	$	(1,433	)	$	(309	)

		Total (provision) benefit	$	(3,320	)	$	17,731		$	(15,267	)
		Tax Rate Reconciliation
		Income tax (provision) benefit differed from the amounts computed by applying the U.S. federal income tax rate to pretax income as a result of the following:
			Year Ended
			January 2,			January 1,			December 30,
			2011			2012			2012
		Federal statutory rate		34	%		35	%		35	%

		State income taxes, net of federal benefit		6.22			4.03			5.17
		Nondeductible transaction costs		—			—			3.38
		Other, net		0.36			0.22			0.36
		Effective tax rate		40.58	%		39.25	%		43.91	%
		Deferred Taxes
		Significant components of the Company’s deferred tax assets and deferred tax liabilities are as follows:
			As Of
			January 1,			December 30,
			2012			2012
		Deferred tax assets
		Employee benefits	$	6,911		$	13,731
		Net operating loss carryforwards and tax credits		13,386			10,945
		Lease related		41,192			54,798
		Other accrued liabilities		5,809			5,048
		Intangible assets		26,331			17,917
		Inventories and other		151			1,401
		Total gross deferred tax assets		93,780			103,840
		Deferred tax liabilities
		Depreciation and amortization		(34,653	)		(56,670	)
		Total gross deferred tax liabilities		(34,653	)		(56,670	)
		Net deferred tax asset	$	59,127		$	47,170
		A valuation allowance is established for deferred tax assets if it is more likely than not that these items will either expire before the Company is able to realize their benefits, or that the realization of future deductions is uncertain.
		Management performs an assessment over future taxable income to analyze whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company has evaluated all available positive and negative evidence and believes it is probable that the deferred tax assets will be realized and has not recorded a valuation allowance against the Company’s deferred tax assets as of January 1, 2012 and December 30, 2012.
		At January 1, 2012 and December 30, 2012, the Company has approximately $36.1 million and $28.4 million of federal net operating loss carryforwards, respectively, which are available to offset future federal taxable income 2028 through 2031. The Company has net operating loss carryforwards for state income tax purposes of $11.2 million and $7.8 million as of January 1, 2012 and December 30, 2012, respectively, which are available to offset future state taxable income 2013 through 2031. The utilization of certain of the Company’s net operating loss carryforwards may be limited in a given year. The Company has alternative minimum tax credits of $0.5 million which are available to offset future income taxes. These credits have no expiration date.
		Federal tax laws impose restrictions on the utilization of net operating loss carryforwards and tax credit carryforwards in the event of an “ownership change,” as defined by federal income tax code. Such an ownership change occurred on May 29, 2012, concurrent with the acquisition of Sunflower. The Company’s ability to utilize net operating loss carryforwards and tax credit carryforwards is subject to restrictions pursuant to these provisions. Utilization of the federal net operating loss and tax credits will be limited annually and any unused limitation in a given year may be carried forward to the next year.
		The Company applies the authoritative accounting guidance under ASC 740 for the recognition, measurement, classification and disclosure of uncertain tax positions taken or expected to be taken in a tax return.
		A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:
			As Of
			January 2,			January 1,			December 30,
			2011			2012			2012
		Beginning balance	$	204		$	307		$	—
		Additions based on tax positions related to the current year		307			—			150
		Reductions for tax positions of prior years		(204	)		(307	)		—
		Net deferred tax asset (liability)	$	307		$	—		$	150
		At January 2, 2011 and December 30, 2012 the Company had unrecognized tax benefits of $0.3 million and $0.2 million (tax effected) that would impact the effective tax rate if recognized.
		The Company’s policy is to recognize accrued interest and penalties as a component of income tax expense.
		The Company anticipates an increase in the total amount of unrecognized tax benefits during the next twelve months related to depreciation for transaction cost allocation in the amount of $0.2 million.
		The Company files income tax returns with federal and state tax authorities within the United States. The statute of limitations remains open for federal and state income tax examinations for the tax year 2011. The statute of limitations remains open for Sunflower’s pre-merger federal tax returns for 2010 through 2012 and state tax returns for 2007 through 2012.

	During 2012, the Company incurred costs related to its use of a private aircraft owned by an entity controlled by a member of the Company’s board of directors. Fees paid in connection with the use of the aircraft were $0.3 million during the thirty-nine weeks ended September 30, 2012. During the third quarter of 2012, the Company purchased the aircraft for $3.2 million.	Transactions with S&F
	Two stockholders, including a member of the Company’s board of directors, are investors in a company that is a supplier of coffee to the Company. During the thirty-nine weeks ended September 30, 2012 and September 29, 2013, purchases from this company were $3.7 million and $5.6 million, respectively. As of December 30, 2012 and September 29, 2013, the accounts receivable amount the Company had recorded from this vendor related to vendor rebates was $0.4 million and not material, respectively. As of December 30, 2012 and September 29, 2013, the Company had recorded accounts payable due to this vendor of $0.7 million and $0.6 million, respectively.	Prior to the April 18, 2011, transactions between Henry’s and S&F and its wholly owned subsidiaries commonly occurred in the normal course of business. These transactions included allocation of corporate costs, Henry’s participation in S&F’s centralized cash management system, self-insurance and share-based compensation plans as described further below.
	On August 30, 2007, Sprouts Arizona entered into a services agreement (the “Services Agreement”) with an outsourced service provider who is a stockholder of the Company, to perform substantially all of the Company’s bookkeeping services including among other matters, general ledger maintenance, payroll processing, accounts payable processing, accounts receivable processing, and management reporting. The initial term of the Services Agreement was September 1, 2007 through September 1, 2009 with automatic renewal for successive one-year terms unless either party provides six months’ termination notice. During the thirty-nine weeks ended September 30, 2012 and September 29, 2013, fees and other expenses paid to the service provider under the terms of the Services Agreement were $2.2 million and $1.8 million, respectively. The Company has an option to terminate the Services Agreement early for a termination fee of $100,000. If this arrangement were to be terminated, the inability of a third-party service provider to resume these services on a timely basis would impact the Company’s business and operating results.	Corporate Allocations
	As of December 30, 2012, $1.0 million of the Senior Subordinated Promissory Notes were held by certain members of senior management of the Company. The Company repaid these amounts as part of full repayment of the Senior Subordinated Promissory Notes on May 31, 2013. See Note 7, “Long-Term Debt” for more information.	S&F and its wholly owned subsidiaries provided corporate and other services to Henry’s in the normal course of business. The financial statements for 2010 and for 2011 through the April 17, 2011 include charges from S&F to Henry’s for corporate expenses relating to these transactions and services, using the following methodologies:
		Direct Costs—costs incurred by S&F and its wholly owned subsidiaries on behalf of Henry’s were charged directly to the Company. Direct costs relate to store lease payments, common area maintenance charges, utilities, store design and construction costs, distribution service charges and other specifically identifiable costs. These specific costs are included within individual line items in the accompanying consolidated statements of operations.
		Allocated Corporate Expenses—corporate overhead costs not specifically charged to Henry’s were generally allocated based on Henry’s sales, number of stores, case volume shipped or number of employees in relation to totals for S&F. Allocated corporate costs relate to real estate management, store design and construction, distribution services and general corporate services. Costs amounting to $7.2 million and $2.6 million allocated to Henry’s for the years ended January 2, 2011 and January 1, 2012, respectively, are included in the accompanying consolidated statements of operations. Those costs were previously presented as “allocated corporate costs”, but have been reclassified to costs of sales, buying and occupancy, direct store expenses and selling, general and administrative expenses as appropriate for the character of each cost item.
		Management believes the allocation methodology described above is a fair and reasonable reflection of the utilization of the services provided to, or the benefit received by, Henry’s during the periods presented. The allocations may not, however, reflect the expense Henry’s would have incurred as an independent company for the periods presented. Actual costs that may have been incurred if Henry’s had been a stand-alone company would depend on a number of factors, including the chosen organization structure, what functions were outsourced or performed by employees, and strategic decisions made in the areas such as information technology and infrastructure.
		Henry’s operated a 241,000 square-foot leased facility primarily dedicated to produce fulfillment which served both Henry’s and S&F. The operations of the facility have been included in the accompanying consolidated financial statements of the Company through April 17, 2011 and costs of the facility have been allocated to Smart & Final Stores based on case volume shipped. On April 18, 2011, S&F kept the operations and assets and liabilities of the warehouse facility and the distribution of these assets and liabilities to S&F is netted with other assets and liabilities contributed to Henry’s and reflected as a contribution by S&F in equity, discussed in Note 2, “Basis of Presentation.”
		S&F also operated under a Management Services Agreement with an Apollo affiliate, Apollo Management VI, L.P. whereby the Apollo affiliate provided certain investment banking, management, consulting and financial planning services to S&F. The Management Services Agreement was for a ten-year term starting in 2007 and S&F was obligated to pay the Apollo affiliate an annual fee of $1.5 million, payable on a quarterly basis. The management fees allocated to Henry’s as part of the allocated corporate expenses by S&F were $0.3 million and $0.1 million during 2010 and 2011, respectively.
		S&F Centralized Cash Management
		Henry’s participated in S&F’s centralized cash management system through the April 17, 2011. The majority of cash received from the Henry’s operations was transferred to S&F’s centralized cash accounts and cash disbursements of Henry’s were funded from the centralized cash accounts on a daily basis as needed. The cash and cash equivalents held by S&F at the corporate level were not allocated to Henry’s for any of the periods presented. Transfers of cash to and from S&F’s cash management system were reflected as S&F equity on the accompanying consolidated statements of stockholders’ equity. No interest was charged or earned on the cash management account. Under this system, Henry’s had no external sources of financing, such as available lines of credit, as may be necessary to operate as a stand-alone entity.
		Up to April 17, 2011, all significant intercompany transactions between Henry’s and S&F and its other subsidiaries have been included in the accompanying consolidated financial statements and were considered to be effectively settled for cash at the time the transaction was recorded. The total net effect of the settlement of these intercompany transactions is reflected in the accompanying consolidated statements of cash flows as a financing activity and in the accompanying consolidated balance sheets as stockholders’ equity. After April 17, 2011, all transactions between the Company and S&F were settled in cash.
		S&F Share-Based Compensation
		S&F granted stock options to employees under the S&F Stock Incentive Plan in which some of the Henry’s employees participated. Accounting guidance requires all share-based payments to be recognized in the statement of operations as compensation expense based on their fair values over the requisite service period of the award, taking into consideration estimated forfeiture rates.
		The fair value of the options was estimated on the date of the grant using the Black-Scholes-Merton option-pricing model. S&F recognized the related compensation expense (the estimated fair value of the stock options) over the vesting period using the accelerated recognition method.
		Compensation expense allocated to Henry’s for employees participating in the S&F Stock Incentive Plan amounted to $0.2 million and $0.0 million for 2010 and 2011, respectively.
		S&F Equity
		Prior to April 18, 2011, equity refers to the consolidated net assets of Henry’s which reflects S&F’s consolidated investment in Henry’s. Equity was impacted by capital contributions, cumulative net earnings of Henry’s, certain operational billings and payments/receipts between Henry’s and S&F, centralized cash management by S&F and general corporate and tax allocations from S&F.

		Total	$	(179,182	)	$	(54,057	)
		Pursuant to the Transaction, S&F entered into a Transition Services Agreement (“TSA”), under which S&F received compensation for providing certain post-transaction support services to the Company for a period up to 180 days after the Close Date. These services include warehousing and distribution, information technology support, human resources and payroll support as well as various other administrative support services. Total expenses incurred in connection with the TSA during 2011 amounted to $4.7 million.
		Transactions with Other Related Parties
		The Company incurred costs related to its use of a private aircraft owned by a member of senior management, which was purchased by the Company during 2012. During 2011 and 2012, fees paid in connection with the use of the aircraft were $0.4 million and $0.6 million, respectively. During 2012, the Company purchased the aircraft for $3.2 million.
		Two stockholders are investors in a company that is a supplier of coffee to the Company. During 2011 and 2012, purchases from this company were $3.4 million and $5.6 million, respectively. As of December 30, 2012, the Company had recorded $0.4 million of accounts receivable due from this vendor related to vendor rebates. As of January 1, 2012 and December 30, 2012, the Company had recorded accounts payable due to this vendor of $0.4 million and $0.7 million, respectively.
		On August 30, 2007, Sprouts Arizona entered into a services agreement with an outsourced service provider who is a stockholder of the Company, to perform substantially all of the Company’s bookkeeping services including among other matters, general ledger maintenance, payroll processing, accounts payable processing, accounts receivable processing, and management reporting.

During 2010, 2011 and 2012, fees and other expenses paid to the service under the terms of the Services Agreement were $2.2 million, $2.2 million and $2.7 million, respectively. The Company has an option to terminate the agreement early for a termination fee of $100,000. If this arrangement were to be terminated, the inability of a third-party service provider to resume these services on a timely basis would impact the Company’s business and operating results.
		As of December 30, 2012, $1.0 million of the Senior Subordinated Promissory Notes were held by certain members of senior management of the Company.

The Company received gross proceeds from the IPO of approximately $368.6 million, or $344.1 million after deducting underwriting discounts and offering expenses of $24.5 million. The Company did not receive any proceeds from the sale of shares by the selling stockholders. On August 6, 2013, the Company used $340.0 million of the net proceeds from its IPO to make a partial repayment of the Term Loan. See Note 7, “Long-Term Debt” for more information.	As of December 30, 2012, 125,956,721 shares of common stock have been issued by the Company, the majority of which, 51.2% and 36.3%, are held by the Apollo Funds and the Liquidating Trust, respectively. As of December 30, 2012, 12,100,000 shares of common stock are reserved for issuance under the Sprouts Farmers Markets, LLC Option Plan (see Note 24, “Equity-Based Compensation”). During 2012, options were exercised in exchange for the issuance of 189,585 shares of common stock and subsequently, the Company repurchased 24,585 of the shares of common stock.
	Distribution to Stockholders
	On April 24, 2013, the Company paid a total distribution of $282.0 million to stockholders. Additionally, pursuant to the anti-dilution provisions of the 2011 Option Plan (as defined in Note 14 “Equity-Based Compensation” below), the Company paid $13.9 million to certain vested option holders and reduced the exercise price on unvested and certain vested options.	Equity prior to April 18, 2011 represents the consolidated net assets of Henry’s, which reflected S&F’s consolidated investment in Henry’s. Activity in the consolidated statement of stockholders’ equity prior to April 18, 2011 is summarized in Note 19, “Related-Party Transactions.”
	The payment was made first from retained earnings to date as of the payment date, and payment in excess of retained earnings was made from additional paid-in capital.	Weighted average shares outstanding for periods prior to the Henry’s Transaction assume the same shares outstanding as immediately after the transaction per accounting guidance.
		During the year, 62,271 of the Company’s shares that were previously held in escrow pursuant to indemnification arrangements set forth in agreements entered into in connection with the Sunflower Transaction were forfeited pursuant to the terms of such agreements and redistributed to certain Company equity holders in accordance with the terms of such agreements and the Company’s LLC Agreement.
		Preferred Stock
		The Company’s board of directors is authorized, subject to limitations prescribed by Delaware law, to issue up to 10,000,000 shares of the Company’s preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, to fix the designation, powers, preferences, and rights of the shares of each series and any of its qualifications, limitations, or restrictions, in each case without further action by the Company’s stockholders. The Company’s board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding. The Company’s board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring, or preventing a change in control of the Company and might adversely affect the market price of the Company’s common stock and the voting and other rights of the holders of the Company’s common stock. The Company has no current plan to issue any shares of preferred stock.

	15. Equity-Based Compensation							24. Equity-Based Compensation
	2013 Incentive Plan							In May 2011, the Company adopted the Sprouts Farmers Markets, LLC Option Plan (the “Option Plan”) to provide employees or directors of the Company with options to acquire shares of the Company (“options”). The Company had authorized 12,100,000 shares for issuance under the Option Plan of which 11,572,990 such options have been granted as of December 30, 2012.
	The Company’s board of directors adopted, and its equity holders approved, the Sprouts Farmers Market, Inc. 2013 Incentive Plan (the “2013 Incentive Plan”). The 2013 Incentive Plan became effective July 31, 2013 in connection with the Company’s IPO and replaced the 2011 Option Plan (except with respect to outstanding options under the 2011 Option Plan). The 2013 Incentive Plan serves as the umbrella plan for the Company’s stock-based and cash-based incentive compensation programs for its directors, officers and other team members.							Options are granted to certain employees at a price determined by the Board in its sole discretion. The maximum contractual term for such options is seven years. The options vest in accordance with the terms set forth in the grant letter and vary depending on if they are time-based or performance-based. Time-based options generally vest ratably over a period of 12 quarters (three years) and performance-based options vest over a period of three years based on financial performance targets set for each year. In the event of a change in control as defined in the Option Plan, all options become immediately vested and exercisable.
	Under the 2013 Incentive Plan, effective July 31, 2013 upon the pricing of the Company’s IPO, the Company granted to certain officers and team members options to purchase 396,000 shares of common stock at an exercise price of $18.00 per share, with grant date fair values $4.65 to $5.92. The Company also granted to independent directors options to purchase 11,112 shares of common stock at an exercise price of $18.00 per share, with a grant date fair value of $4.65.							The estimated fair values of options granted during 2011 and 2012 range from $1.07 to $3.09, and were calculated using the following assumptions:
	The aggregate number of shares of common stock that may be issued to team members and directors under the 2013 Incentive Plan may not exceed 10,089,072. Shares subject to awards granted under the 2013 Incentive Plan which are subsequently forfeited, expire unexercised or are otherwise not issued will not be treated as having been issued for purposes of the share limitation.								2011			2012
	2011 Option Plan							Dividend yield		0.00%			0.00%
	In May 2011, the Company adopted the Sprouts Farmers Markets, LLC Option Plan (the “2011 Option Plan”) to provide employees or directors of the Company with options to acquire shares of the Company (“options”). The Company had authorized 12,100,000 shares for issuance under the 2011 Option Plan. Options may no longer be issued under the 2011 Option Plan.							Expected volatility		38.58% to 41.18%			32.36% to 38.59%
	During the thirty-nine weeks ended September 29, 2013, the Company awarded 209,000 options to employees under the 2011 Option Plan at exercise prices of $9.15 and grant date fair values of $2.33 to $3.10.							Risk free interest rate		0.57% to 1.88%			0.40% to 0.77%
	The Company uses the Black-Scholes option pricing model to estimate the fair value of options at grant date. Options vest in accordance with the terms set forth in the grant letter and vary depending on if they are time-based or performance-based. Time-based options generally vest ratably over a period of 12 quarters (three years) and performance-based options vest over a period of three years based on financial performance targets set for each year. In the event of a change in control as defined in the 2011 Option Plan, all options under such plan become immediately vested and exercisable.							Expected life, in years		3.63 to 4.83			3.75 to 5.00
	Equity-based compensation expense was reflected in the consolidated statements of operations as follows:							The grant date weighted average fair value of options granted was $1.12 and $1.99 for 2011 and 2012, respectively. The grant date weighted average fair value of options forfeited during 2012 was $1.17. The total grant date fair value of the options vested during 2011 and 2012 was $2.6 million and $4.5 million, respectively, including the value of vested options exercised during those same periods. The grant date weighted average fair value of the 6,906,229 options issued but not vested as of January 1, 2012 was $1.14. The grant date weighted average fair value of the 5,824,170 options issued but not vested as of December 30, 2012 was $1.45.
								Expected volatility is calculated based upon historical volatility data from a group of comparable companies and expectations of future volatility over a timeframe consistent with the expected life of the awards. The expected life is estimated based on the expected period that the options are anticipated to be outstanding after initial grant until exercise or expiration based upon various factors including expectations concerning a potential liquidity event, the contractual terms of the awards and vesting schedules. The expected risk-free rate is based on the U.S. Treasury yield curve rates in effect at the time of the grant using the term most consistent with the expected life of the award. Dividend yield was estimated at zero as the Company does not anticipate making regular future distributions to stockholders.

	2. Recently Issued Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-04, “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (a consensus of the FASB Emerging Issues Task Force),” which amends Accounting Standards Codification (“ASC”) 405, “Liabilities.” The amendments provide guidance on the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements, including debt arrangements, other contractual obligations, and settled litigation and judicial rulings, for which the total amount of the obligation is fixed at the reporting date. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied retrospectively. The provisions are effective for the Company’s first quarter of 2014. The Company does not expect adoption of this guidance to have a material effect on its consolidated financial statements.
	During the second fiscal quarter of 2013, the Company adopted ASU 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which clarifies how to report the effect of significant reclassifications out of accumulated other comprehensive income. The adoption concerns presentation and disclosure only, and as the Company does not have items of other comprehensive income, it did not have an impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists,” which amends ASC 740, “Income Taxes.” ASU No. 2013-11 requires that unrecognized tax benefits be classified as an offset to deferred tax assets to the extent of any net operating loss carryforwards, similar tax loss carryforwards, or tax credit carryforwards available at the reporting date in the applicable tax jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position. An exception would apply if the tax law of the tax jurisdiction does not require the Company to use, and it does not intend to use, the deferred tax asset for such purpose. This guidance is effective for reporting periods beginning after December 15, 2013. The Company does not expect the adoption of these provisions to have a material effect on the consolidated financial statements.

Fair Value Measurements	'
	3. Fair Value Measurements
	The Company records its financial assets and liabilities in accordance with the framework for measuring fair value in accordance with GAAP. This framework establishes a fair value hierarchy that prioritizes the inputs used to measure fair value:
	Level 1: Quoted prices for identical instruments in active markets.
	Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
	Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
	Fair value measurements of nonfinancial assets and nonfinancial liabilities are primarily used in the impairment analysis of goodwill, intangible assets, long-lived assets and in the valuation of store closure and exit costs.
	SPROUTS FARMERS MARKET, INC. AND SUBSIDIARIES
	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(UNAUDITED)
	The determination of fair values of certain tangible and intangible assets for purposes of the Company’s goodwill impairment evaluation as described above was based upon Level 3 inputs. Closed store reserves are recorded at net present value to approximate fair value which is classified as Level 3 in the hierarchy. The estimated fair value of the closed store reserve is calculated based on the present value of the remaining lease payments and other charges using a weighted average cost of capital, reduced by estimated sublease rentals. The weighted average cost of capital was estimated using information from comparable companies and management’s judgment related to the risk associated with the operations of the stores.
	Cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued salaries and benefits and other accrued liabilities approximate fair value because of the short maturity of those instruments. Based on open market transactions comparable to the Term Loan and Former Term Loan (as defined in Note 7, “Long-Term Debt”), the fair value of the long-term debt, including current maturities, approximates carrying value as of December 30, 2012 and September 29, 2013. The carrying amount of the Senior Subordinated Promissory Notes (as defined in Note 7, “Long-Term Debt”) approximates fair value as its terms are consistent with current market rates as of December 30, 2012. The Company’s estimates of the fair value of long-term debt (including current maturities) and the Senior Subordinated Promissory Notes were classified as Level 2 in the fair value hierarchy.

Significant Accounting Estimates	'	'
		Significant Accounting Estimates
		The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities and the 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. The Company’s critical estimates included, but are not limited to: inventory valuations, lease assumptions, sublease assumptions for closed stores, self-insurance reserves, goodwill and intangible assets, impairment of long-lived assets, fair values of equity-based awards and income taxes. Actual results could differ from those estimates.
Cash and Cash Equivalents	'	'
		Cash and Cash Equivalents
		The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. The Company’s cash and cash equivalents are maintained at financial institutions in the United States of America. Deposits in these financial institutions may, from time to time, exceed the Federal Deposit Insurance Corporation’s (“FDIC”) federally insured limits. All credit and debit card transactions are also classified as cash and cash equivalents. The amounts due from banks for these transactions at each reporting date were as follows:

Accounts Receivable	'	'
		Accounts Receivable
		Accounts receivable generally represent billings to vendors for earned rebates and allowances and other items. When a specific account is determined uncollectible, the net recognized receivable is written off. As of December 30, 2012, the Company had recorded an allowance of $0.3 million for certain receivables. As of January 1, 2012, no allowance was recorded.
Inventories	'	'
		Inventories
		Inventories consist of merchandise purchased for resale, which are stated at the lower of cost or market. The cost method is used for warehouse perishable and store perishable department inventories by assigning costs to each of these items based on a first-in, first-out (FIFO) basis (net of vendor discounts).
		Effective January 3, 2011, the Company changed its accounting policy for non-perishable inventories from the lower of cost or market using the retail inventory method (“RIM”) to the lower of cost or market using weighted average costs. The Company’s valuation of its non-perishable inventory using weighted average costs includes statistical and other estimation methods which the Company believes provide a reasonable basis to estimate its inventory values at the end of the respective periods.
		The Company believes that this new method for valuing its non-perishable products is preferable as weighted average costs results in a more accurate measure of actual inventory costs than RIM, which involves estimates of inventory costs based on an accumulation of inventory at retail price and purchase costs. The weighted average costs method of valuing inventory will also improve the comparability of the Company’s financial results with those of its competitors.
		Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 250, “Accounting Changes and Error Corrections,” requires that a change in accounting principle be reported through retrospective application of the new accounting principle to all prior periods, unless impracticable. The Company concluded retrospective application was impracticable for periods prior to 2011 because the information is not available without undue cost and effort. The Company believes the effect of the change in accounting principle as of January 3, 2011 was not material.
		The Company believes that all inventories are saleable and no allowances or reserves for shrinkage or obsolescence were recorded as of January 1, 2012 and December 30, 2012.
Property and Equipment	'	'
		Property and Equipment
		Property and equipment are stated at cost, net of accumulated depreciation and amortization. Expenditures for major additions and improvements to facilities are capitalized, while maintenance and repairs are charged to expense as incurred. When property is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations. Depreciation expense, which includes the amortization of assets recorded under capital and financing leases, is computed using the straight-line method over the estimated useful lives of the individual assets. Leasehold improvements and assets under capital and financing leases are amortized over the shorter of the lease term to which they relate, or the estimated useful life of the asset. Terms of leases used in the determination of estimated useful lives may include renewal options if the exercise of the renewal option is determined to be reasonably assured.
		The following table includes the estimated useful lives of asset classes:
		Software and used equipment		3 years
		Computer hardware		5 years
		Furniture, fixtures and equipment		7 years
		Leasehold improvements		up to 15 years
		Buildings		40 years
		Store development costs, which include costs associated with the selection and procurement of real estate sites, are also included in property and equipment. These costs are included in leasehold improvements and are amortized over the remaining lease term of the successful sites with which they are associated. Certain project costs, including general site selection costs that cannot be identified with a specific store location, are charged to direct store expenses in the accompanying consolidated statements of operations.
Asset Retirement Obligations	'	'
		Asset Retirement Obligations
		The Company’s asset retirement obligations (“ARO”) are related to the Company’s commitment to return leased facilities to the landlord in an agreed upon condition. This may require actions ranging from cleaning to removal of leasehold improvements. The obligation is recorded as a liability with an offsetting capital asset at the inception of the lease term based upon the estimated fair market value of costs to meet the commitment. The liability, included in other long-term liabilities in the consolidated balance sheets, is accreted over time to the projected future value of the obligation. The ARO asset, included in property and equipment in the consolidated balance sheets, is depreciated using the same useful life as the related property.
		A reconciliation of the ARO liability is as follows:
			As Of
			January 1,			December 30,
			2012			2012
		Beginning balance	$	580		$	1,236
		Additions for new facilities		110			132
		ARO liability from business combination		531			784
		Accretion expense		36			237
		Reduction due to lease exits		—			(11	)
		Adjustments		(21	)		(16	)
		Ending balance	$	1,236		$	2,362
Closed Store Reserve	'	'
		Closed Store Reserve
		The Company recognizes a reserve for future operating lease payments associated with facilities that are no longer being utilized in its current operations. The reserve is recorded based on the present value of the remaining noncancelable lease payments after the cease use date less an estimate of subtenant income. If subtenant income is expected to be higher than the lease payments, no accrual is recorded. Lease payments included in the closed store reserve are expected to be paid over the remaining terms of the respective leases. The Company’s assumptions about subtenant income are based on the Company’s experience and knowledge of the area in which the closed property is located, guidance received from local brokers and agents and existing economic conditions. Adjustments to the closed store reserve relate primarily to changes in actual or estimated subtenant income and actual lease payments from original estimates. Adjustments are made for changes in estimate in the period in which the change becomes known considering timing of new information regarding the market, subleases or other lease updates. Adjustments in the closed store reserves are recorded in “store closure and exit costs” in the consolidated statements of operations.
Self-Insurance Reserves	'	'
		Self-Insurance Reserves
		The Company uses a combination of insurance and self-insurance programs to provide reserves for potential liabilities associated with general liability, workers’ compensation and employee health benefits. Liabilities for self insurance reserves are estimated through consideration of various factors, which include historical claims experience, demographic factors, severity factors and other actuarial assumptions.
Goodwill and Intangible Assets	'	'
		Goodwill and Intangible Assets
		Goodwill represents the cost of acquired businesses in excess of the fair value of assets and liabilities acquired. The Company’s indefinite-lived intangible assets consist of trade names related to “Sprouts Farmers Market” and liquor licenses. The Company also holds intangible assets with finite useful lives, consisting of favorable and unfavorable leasehold interests and the “Sunflower Farmers Market” trade name.
		Goodwill is evaluated for impairment on an annual basis during the fourth fiscal quarter or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company’s impairment evaluation of goodwill consists of a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company’s qualitative assessment indicates it is more likely than not that the estimated fair value of a reporting unit exceeds its carrying value, no further analysis is required and goodwill is not impaired. Otherwise, the Company follows a two-step quantitative goodwill impairment test to determine if goodwill is impaired. The first step of the quantitative goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of the Company’s reporting unit exceeds its carrying value, no further analysis or impairment of goodwill is required. If the carrying value of the Company’s reporting unit exceeds its fair value, the fair value of the reporting unit would be allocated to the reporting unit’s assets and liabilities based on the relative fair value, with goodwill written down to its implied fair value, if necessary.
		Indefinite-lived assets are evaluated for impairment on an annual basis during the fourth fiscal quarter or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company’s impairment evaluation for its indefinite-lived intangible assets consists of a qualitative assessment similar to that for goodwill. If the Company’s qualitative assessment indicates it is more likely than not that the estimated fair value of an indefinite-lived intangible asset exceeds its carrying value, no further analysis is required and the asset is not impaired. Otherwise, the Company compares the estimated fair value of the asset to its carrying amount with an impairment loss recognized for the amount, if any, by which carrying value exceeds estimated fair value.
		The Company can elect to bypass the qualitative assessments approach for goodwill and indefinite-lived intangible assets and proceed directly to the quantitative assessments for goodwill or any indefinite-lived intangible assets in any period. The Company can resume the qualitative assessment approach in future periods.
		The Company has determined its business consists of a single reporting unit. When applying the quantitative test, the Company determines the fair value of its reporting unit using the income approach methodology of valuation that includes the discounted cash flow method as well as other generally accepted valuation methodologies.
		The Company completed its goodwill and indefinite-lived intangible asset impairment evaluations as of the first day of the fourth quarter and concluded during 2010, 2011 and 2012 that there was no impairment. The Company also concluded that events and circumstances continued to support classifying its indefinite-lived intangible assets as such. See Note 8, “Intangible Assets” and Note 9, “Goodwill” for further discussion.
		Prior to the Henry’s Transaction, the trade names related to “Henry’s Farmers Markets” were accounted for as finite-lived intangible assets and amortized on a straight-line basis over an estimated useful life of 20 years. As a result of the rebranding of the “Henry’s Farmers Markets” locations as “Sprouts Farmers Market” locations following the Henry’s Transaction, the estimated remaining useful lives of these trade names were re-evaluated and amortization was accelerated through the end of their respective useful life in fiscal 2011, when it was subsequently written-off. See Note 8, “Intangible Assets” for further discussion. The trade name related to “Sunflower Farmers Market” meets the definition of a defensive intangible asset and is amortized on a straight line basis over an estimated useful life of 10 years from the date of its acquisition by the Company. Favorable and unfavorable leasehold interests are amortized on a straight-line basis over the lease term.
Impairment of Long-Lived Assets	'	'
		Impairment of Long-Lived Assets
		The Company assesses its long-lived assets, including property and equipment and finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. The Company groups and evaluates long-lived assets for impairment at the individual store level, which is the lowest level at which independent identifiable cash flows are available. Factors which may indicate potential impairment include a significant underperformance relative to the historical or projected future operating results of the store or a significant negative industry or economic trend. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by that asset. If impairment is indicated, a loss is recognized for any excess of the carrying value over the estimated fair value of the asset group. The fair value is estimated based on the discounted future cash flows or comparable market values, if available. The Company did not record any impairment loss during 2010, 2011 or 2012.
Deferred Financing Costs	'	'
		Deferred Financing Costs
		The Company capitalizes certain fees and costs incurred in connection with the issuance of debt. Deferred financing costs are amortized to interest expense over the term of the debt using the effective interest method. For the Revolving Credit Facility, deferred financing costs are amortized on a straight line basis over the term of the facility. Upon prepayment, redemption or conversion of debt, the Company accelerates the recognition of an appropriate amount of financing costs as additional interest expense. The current and noncurrent portions of deferred financing costs are included in prepaid expenses and other current assets and other assets, respectively, in the consolidated balance sheets.
Operating Leases	'	'
		Operating Leases
		The Company leases stores, warehouse facilities and administrative offices under operating leases.
		Incentives received from lessors are deferred and recorded as a reduction of rental expense over the lease term using the straight-line method. The current portion of unamortized lease incentives is included in other accrued liabilities and the noncurrent portion is included in other long-term liabilities in the accompanying consolidated balance sheets.
		Store lease agreements generally include rent abatements and rent escalation provisions and may include contingent rent provisions based on a percentage of sales in excess of specified levels. The Company recognizes escalations of minimum rents and/or abatements as deferred rent and amortizes these balances on a straight-line basis over the term of the lease.
		For lease agreements that require the payment of contingent rents based on a percentage of sales above stipulated minimums, the Company begins accruing an estimate for contingent rent when it is determined that it is probable the specified levels of sales in excess of the stipulated minimums will be reached during the year.
Financing Lease Obligations	'	'
		Financing Lease Obligations
		The Company has recorded financing lease obligations for 22 and 31 store building leases as of January 1, 2012 and December 30, 2012, respectively. In each case, the Company was deemed to be the owner during the construction period under lease accounting guidance. Further, each lease contains provisions indicating continuing involvement with the property at the end of the construction period which include either an affiliate guaranty or contingent collateral. As a result, in accordance with applicable accounting guidance, buildings and related assets subject to the leases are reflected on the Company’s balance sheets and depreciated over their remaining useful lives. The present value of the lease payments associated with these buildings is recorded as financing lease obligations.
		Monthly lease payments are allocated between the land element of the lease (which is accounted for as an operating lease) and the financing obligation. The financing obligation is amortized using the effective interest method and the interest rate is determined in accordance with the requirements of sale-leaseback accounting. Lease payments less the portion allocated to the land element of the lease and that portion considered to be interest expense decrease the financing liability. At the end of the initial lease term, should the Company decide not to renew the lease, the net book value of the asset and the corresponding financing obligation would be reversed.
		The outflows from the construction of the buildings are classified as investing activities, and the outflows associated with the financing obligations principal payments and inflows from the associated financing proceeds are classified as financing activities in the accompanying consolidated statements of cash flows.
Fair Value Measurements	'	'
		Fair Value Measurements
		The Company records its financial assets and liabilities in accordance with the framework for measuring fair value in accordance with GAAP. This framework establishes a fair value hierarchy that prioritizes the inputs used to measure fair value:
		Level 1: Quoted prices for identical instruments in active markets.
		Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
		Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
		Fair value measurements of nonfinancial assets and nonfinancial liabilities are primarily used in the impairment analysis of goodwill, intangible assets, long-lived assets and in the valuation of store closure and exit costs.
		The determination of fair values of certain tangible and intangible assets for purposes of our goodwill impairment evaluation as described above was based upon level 3 inputs. Closed store reserves are recorded at net present value to approximate fair value which is classified as Level 3 in the hierarchy. The estimated fair value of the closed store reserve is calculated based on the present value of the remaining lease payments and other charges using a weighted average cost of capital, reduced by estimated sublease rentals. The weighted average cost of capital was estimated using information from comparable companies and management’s judgment related to the risk associated with the operations of the stores.
		Cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued salaries and benefits and other accrued liabilities approximate fair value because of the short maturity of those instruments. Based on comparable open market transactions of the Term Loan (as defined in Note 13, “Long-Term Debt”), the fair value of the long-term debt, including current maturities, approximates carrying value as of January 1, 2012 and December 30, 2012. The carrying amount of the Senior Subordinated Promissory Notes (as defined in Note 13, “Long-Term Debt”) approximates fair value as its terms are consistent with current market rates as of December 30, 2012. The Company’s estimates of the fair value of long-term debt (including current maturities) and the Senior Subordinated Promissory Notes were classified as Level 2 in the fair value hierarchy.
Business Combinations	'	'
		Business Combinations
		Business combinations are accounted for using the acquisition method of accounting, which requires that the purchase price paid for an acquisition be allocated to the assets and liabilities acquired based on their estimated fair values as of the effective date of the acquisition, with the excess of the purchase price over the net assets being recorded as goodwill. Acquisition-related costs are considered separate transactions and are expensed as incurred. Acquisition-related costs are classified as selling, general and administrative expenses and consist of costs associated with the Henry’s Transaction in 2011 and costs associated with the Sunflower Transaction in 2012, as follows:
			Year Ended
			January 1,			December 30,
			2012			2012
		Acquisition-related costs	$	5,900		$	3,229
		See Note 4, “Business Combinations” for further discussion.
Equity-Based Compensation	'	'
		Equity-Based Compensation
		The Company measures equity-based compensation cost at the grant date based on the fair value of the award and recognizes equity-based compensation cost as expense over the vesting period. As equity-based compensation expense recognized in the consolidated statements of operations is based on awards ultimately expected to vest, the amount of expense has been reduced for estimated forfeitures and trued up for actual forfeitures. The Company’s forfeiture rate is estimated primarily based on historical data. The actual forfeiture rate could differ from these estimates. The Company uses the Black-Scholes option-pricing model to determine the grant date fair value for each option grant. The Black-Scholes option-pricing model requires extensive use of subjective assumptions. See Note 24, “Equity-Based Compensation” for a discussion of assumptions used in the calculation of fair values. Application of alternative assumptions could produce different estimates of the fair value of equity-based compensation and, consequently, the related amounts recognized in the accompanying consolidated statements of operations. The Company recognizes compensation cost for time-based awards on a straight-line basis and for performance-based awards on the graded-vesting method over the vesting period of the awards.
Revenue Recognition	'	'
		Revenue Recognition
		Revenue is recognized at the point of sale. Discounts provided to customers at the time of sale are recognized as a reduction in sales as the discounted products are sold. Sales taxes are not included in revenue. Proceeds from the sale of gift cards are recorded as a liability at the time of sale, and recognized as sales when they are redeemed by the customer. The Company has not applied a gift card breakage rate.
		Licensing fees are generated from license agreements related to two former Henry’s stores.
Cost of Sales, Buying and Occupancy	'	'
		Cost of Sales, Buying and Occupancy
		Cost of sales includes the cost of inventory sold during the period, including the direct costs of purchased merchandise (net of discounts and allowances), distribution and supply chain costs, buying costs and supplies. Occupancy costs include store rental, property taxes, utilities, common area maintenance, amortization of favorable or unfavorable leasehold interests and property insurance. The Company recognizes vendor allowances and merchandise volume related rebate allowances as a reduction of inventories during the period when earned and reflects the allowances as a component of cost of sales, buying and occupancy as the inventory is sold.
		Our largest supplier accounted for approximately 17% of total purchases, expressed as a percentage of our cost of sales, buying and occupancy goods, during 2012.
Direct Store Expenses	'	'
		Direct Store Expenses
		Direct store expenses consist of store-level expenses such as salaries and benefits, related equity-based compensation, supplies, depreciation and amortization for buildings and store leasehold improvements, equipment and other store specific costs.
Selling, General and Administrative Expenses	'	'
		Selling, General and Administrative Expenses
		Selling, general and administrative expenses primarily consist of salaries and benefits costs, related equity-based compensation, advertising, acquisition-related costs and corporate overhead.
		The Company charges third-parties to place advertisements in the Company’s in-store guide and newspaper circulars. The Company records consideration received from vendors in connection with cooperative advertising programs as a reduction to advertising costs when the allowance represents a reimbursement of a specific incremental and identifiable cost. Advertising costs are expensed as incurred. Advertising expense was as follows:
			Year Ended
			January 2,			January 1,			December 30,
			2011			2012			2012
		Advertising expense	$	9,342		$	22,344		$	29,238
		Vendor rebates		(1,650	)		(5,745	)		(9,905	)
		Advertising expense, net of rebates	$	7,692		$	16,599		$	19,333
Store Pre-Opening Costs	'	'
		Store Pre-Opening Costs
		Store pre-opening costs include rent expense during construction of new stores and costs related to new store openings, including costs associated with hiring and training personnel and other miscellaneous costs. Store pre-opening costs are expensed as incurred.
Loss on Extinguishment of Debt	'	'
		Loss on Extinguishment of Debt
		The Company recorded a $1.0 million loss on extinguishment of debt in 2012 as a result of the renegotiation of a store lease that was classified as a financing lease obligation.
Income Taxes	'	'
		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 the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. 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. The Company’s deferred tax assets are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. Realization of the deferred tax assets is principally dependent upon achievement of projected future taxable income offset by deferred tax liabilities. Changes in recognition or measurement are reflected in the period in which the judgment occurs. Since becoming a taxable corporation in April 2011, the Company has not recorded any valuation allowances to date on the Company’s deferred income tax assets.
		The Company recognizes the effect of uncertain 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 records interest and penalties related to unrecognized tax benefits as part of income tax expense.
		From a tax perspective, in April 2011, the Company acquired Henry’s. Until April 18, 2011, Henry’s was not a separate tax-paying entity. Henry’s was included in the S&F consolidated federal and certain state income tax groups for income tax reporting purposes. For the period through April 17, 2011, the consolidated financial statements have been prepared on the basis as if Henry’s prepared its tax returns and accounted for income taxes on a separate-company basis. As a result of the Henry’s Transaction, for tax purposes, Henry’s was acquired in a taxable asset acquisition. The purchase price was allocated to all identifiable assets with the residual assigned to tax deductible goodwill. The resulting basis differences between the new tax values and historical amounts resulted in a deferred tax asset of $47.6 million being recorded through membership equity. See Note 18, “Income Taxes” for a discussion of the tax deductibility of goodwill.
		In May 2012, the Company completed the acquisition of a 100% ownership interest in Sunflower. The acquisition was structured to be a tax-free reorganization. The tax basis of the property acquired in reorganization is equal to the basis in the property recorded by Sunflower just prior to the acquisition. The resulting basis difference between the historical tax amounts and the fair values resulted in net deferred tax assets of $1.9 million being recorded through goodwill.
Net Income (Loss) per Share	'	'
	The computation of net income per share is based on the number of weighted average shares outstanding during the period. The computation of diluted net income per share includes the dilutive effect of share equivalents consisting of incremental shares deemed outstanding from the assumed exercise of options.	Net Income (Loss) per Share
		Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the fiscal period.
		Diluted net income (loss) per share is based on the weighted average number of shares outstanding, plus, where applicable, shares that would have been outstanding related to dilutive options.
Comprehensive Income (Loss)	'	'
		Comprehensive Income (Loss)
		Comprehensive income (loss) equals net income (loss) for all periods presented.
Recently Issued Accounting Pronouncements	'	'
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-04, “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date (a consensus of the FASB Emerging Issues Task Force),” which amends Accounting Standards Codification (“ASC”) 405, “Liabilities.” The amendments provide guidance on the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements, including debt arrangements, other contractual obligations, and settled litigation and judicial rulings, for which the total amount of the obligation is fixed at the reporting date. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied retrospectively.	Recently Issued Accounting Pronouncements
		In June 2011, the FASB issued ASU 2011-05 “Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, the FASB issued ASU 2011-12 “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”). ASU 2011-12 deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company adopted this guidance on January 2, 2012 and such adoption did not have a significant effect on the Company’s consolidated financial statements as it has no components of other comprehensive income and is therefore not required to present a statement of comprehensive income.
		In May 2011, the FASB issued Accounting Standards Update (“ASU”) No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends ASC 820, “Fair Value Measurement.” The amended guidance changes the wording used to describe many requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. Additionally, the amendments clarify the FASB’s intent about the application of existing fair value measurement requirements. The guidance provided in ASU No. 2011-04 is effective for interim and annual periods beginning after December 15, 2011 and is applied prospectively. The Company adopted this guidance on January 2, 2012. The adoption of the guidance did not have a significant effect on the Company’s consolidated financial statements.
		In September 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment” (“ASU 2011-08”), which amends ASC 350, “Intangibles-Goodwill and Other”. The objective of the amended guidance is to simplify how entities test goodwill for impairment. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC 350. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The guidance provided in ASU 2011-08 is effective for fiscal years beginning after December 15, 2011. The Company adopted this guidance on January 2, 2012. The adoption of this guidance resulted in a change in how the Company performed its goodwill impairment assessment; however, it did not have a significant effect on the Company’s consolidated financial statements.
		In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which amends ASC 350, “Intangibles-Goodwill and Other”. The amendment guidance simplifies how entities test for impairment of indefinite-lived intangible assets. The amendments permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount as a basis for determining if performing a quantitative test is necessary. The amendments do not change the measurement of impairment losses. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted and the Company has adopted the guidance as of the first day of the fourth quarter of 2012. The adoption of this guidance resulted in a change in how the Company performed its indefinite-lived intangible asset impairment assessment; however, it did not have a significant effect on its consolidated financial statements.
Basis of Accounting	'	'
	The accompanying unaudited consolidated financial statements include the accounts of the Company and its subsidiaries in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. Interim results are not necessarily indicative of results for any other interim period or for a full fiscal year. The information included in these consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto for the fiscal year ended December 30, 2012 included elsewhere in this prospectus.
	On August 6, 2013, the Company completed its initial public offering (“IPO”) of 21,275,000 shares of common stock at a price of $18.00 per share. The Company sold 20,477,215 shares of common stock, and certain stockholders sold the remaining 797,785 shares. The Company received net proceeds from the IPO of $344.1 million, after deducting underwriting discounts and offering expenses. See Note 12, “Stockholders’ Equity” for more information.
	The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.
Segment Reporting	'	'
	The Company has one reportable and one operating segment.
Sales	'	'
	The Company’s business is subject to modest seasonality. Average weekly sales fluctuate throughout the year and are typically highest in the first half of the fiscal year. Produce, which contributed 26% of the Company’s net sales for the thirty-nine weeks ended September 29, 2013, is generally more available in the first six months of the fiscal year due to the timing of peak growing seasons.
Commitments and Contingencies	'	'
	The Company is exposed to claims and litigation matters arising in the ordinary course of business and uses various methods to resolve these matters that are believed to best serve the interests of the Company’s stakeholders. The Company’s primary contingencies are associated with insurance and self-insurance obligations. Estimation of insurance and self-insurance liabilities requires significant judgment and actual claim settlements and associated expenses may differ from the Company’s current provisions for loss.

[1]	In connection with the Henry's Transaction, the Henry's stores were rebranded as Sprouts Farmers Market. The estimated useful lives related to the Henry's trade names and capitalized software were reevaluated and it was determined that amortization of these assets should be accelerated over their estimated remaining useful lives through January 1, 2012. The accelerated amortization was recorded in the statements of operations as Amortization of Henry's trade names and capitalized software and reflected in the additions column of this table. The net book values of these assets were zero as of January 1, 2012 which were written off and are reflected in the adjustment column in this table.
[2]	The Company sold two liquor licenses obtained in the Sunflower Transaction.
[3]	Certain assets and liabilities were distributed to S&F through equity, see Note 4, "Business Combinations" for more detail.
