	1. Business and Basis of Presentation
	Mattress Firm Holding Corp., through its direct and indirect subsidiaries, is engaged in the retail sale of mattresses and bedding-related products in various metropolitan markets in the United States through company-operated and franchisee-owned mattress specialty stores that operate primarily under the name Mattress Firm. Mattress Firm Holding Corp. and its subsidiaries are referred to collectively as the “Company” or “Mattress Firm.”
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”), and they reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly the Company’s financial position as of July 29, 2014, and the results of operations and cash flows for the periods presented. The Company’s historical and quarterly results of operations may not be indicative of the results that may be achieved for the full year or any future period.
	Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the Company’s most recent audited consolidated financial statements and related notes for the fiscal year ended January 28, 2014, which are included in the Company’s Annual Report on Form 10-K filed with the SEC on March 27, 2014 (the “Fiscal 2013 Annual Report”).
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of (i) assets and liabilities, (ii) disclosure of contingent assets and liabilities at the date of the financial statements and (iii) the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Estimates that are more susceptible to change in the near term are the accruals for sales returns and exchanges, product warranty costs, asset impairments, vendor incentives, self-insured liabilities, store closing costs and acquisition accounting fair values.
	The Company is in the process of implementing a new computer system that provides sales tracking, inventory management, financial reporting and warehouse management capabilities (“new ERP system”) to enhance functionality and to support the Company’s growth strategy. The new ERP system utilizes the weighted average cost flow method for determining inventory cost (“Weighted Average”) and, as the new ERP system is rolled out across the Company’s markets, will replace the First-In, First-Out cost flow method (“FIFO”) utilized by our legacy system. The Weighted Average and FIFO methods are both allowable under U.S. GAAP. The Financial Accounting Standards Board (“FASB”) has issued guidance that when there are two allowable alternative accounting principles, a company must determine which one is preferable. The adoption of the Weighted Average method is considered preferable by the Company due to the fact that it aligns with the functionality of the new ERP system. The Company also considered other factors that support preferability of the Weighted Average method, including closer alignment with the physical flow of the Company’s inventories and prevalence among industry peers. Consistent with FASB requirements, if a change in accounting principle is determined to be preferable, the change shall be reported through retrospective application to the financial statements of all prior periods, unless the effects are not material. The Company determined that the effects of adopting the Weighted Average method are not material to its financial statements. This determination is supported by certain inherent characteristics of the Company’s business, including the ability to hold low inventories relative to sales levels, continuous product replenishment, the relatively short life cycles of most mattress product lines and the infrequency of vendor price changes during the life cycle of the majority of products that are carried. Therefore, the change in accounting principle has not been retrospectively applied to prior periods.
	Certain reclassifications have been made to the prior year condensed consolidated statements of cash flows to segregate the cash proceeds related to construction allowances from landlords from the previously reported cash activity that was included as components of the changes in accounts receivable and noncurrent liabilities to conform to the current period financial statement presentation with no effect on the Company’s previously reported net cash provided by operating activities.
	The Company’s fiscal year consists of 52 or 53 weeks ending on the Tuesday closest to January 31. The fiscal year ended January 28, 2014 (“Fiscal 2013”) consisted of 52 weeks. The fiscal year ending February 3, 2015 (“Fiscal 2014”) consists of 53 weeks.

Business Acquisition	'
	2. Acquisitions
	The Company completed a number of acquisitions of the equity interests or operating assets of specialty mattress retailers during the first six months of fiscal 2014. These acquisitions: (i) increase the Company’s store locations and market share in markets in which the Company currently operates, which generally results in expense synergies and improved leverage over market-level costs, such as advertising and warehousing, or (ii) provide an efficient way to enter new markets in which the Company did not previously operate and which provide a platform for further growth. Results of operations of the acquired businesses are included in the Company’s results of operations from the respective effective dates of the acquisitions.
	Effective March 3, 2014, the Company acquired certain leasehold interests, store assets, distribution center assets and related inventories, and assumed certain liabilities of Yotes, Inc. (“Yotes”), a franchisee of the Company, relating to the operation of 34 mattress specialty retail stores located in Colorado and Kansas for a total purchase price of approximately $14.3 million, including working capital adjustments, subject to customary post-closing adjustments.
	Effective March 3, 2014, the Company acquired the leasehold interests and store assets, and assumed certain liabilities, of Southern Max LLC (“Southern Max”), a franchisee of the Company, relating to the operations of three mattress specialty retail stores located in Virginia for a total purchase price of approximately $0.5 million, including working capital adjustments, subject to customary post-closing adjustments.
	Effective April 3, 2014, the Company acquired one hundred percent of the outstanding partnership interests in Sleep Experts Partners, L.P. (“Sleep Experts”), related to the operation of 55 mattress specialty retail stores in Texas under the brand Sleep Experts, for a total purchase price of approximately $67.8 million, including working capital adjustments. The initial purchase price consisted of cash of $62.8 million (net of $1.6 million of cash acquired), and $3.4 million delivered in the form of 71,619 shares of common stock, par value $0.01 per share, of Mattress Firm Holding Corp. common stock as calculated in accordance with the terms of the purchase agreement.
	The Company funded the cash requirements of the Yotes and Southern Max acquisitions using cash reserves and revolver borrowings. The Company raised $100 million of incremental term borrowings under the 2012 Senior Credit Facility (defined in Note 4 below) to fund the cash requirements of the Sleep Experts acquisition and to pay down outstanding revolver borrowings. The new incremental term borrowings mature in January 2016 and are subject to the same interest rate as the existing outstanding incremental borrowings under the 2012 Senior Credit Facility.
	Effective June 4, 2014, the Company acquired substantially all of the mattress specialty retail assets and operations of Mattress Liquidators, Inc. (“Mattress Liquidators”), which operated Mattress King retail stores in Colorado and BedMart retail stores in Arizona, related to the operation of 67 mattress specialty retail stores, for a total purchase price of approximately $32.9 million, giving effect to certain preliminary adjustments, and is subject to further customary adjustments. The purchase price consisted of cash of $29.4 million funded by cash reserves and revolver borrowings, as well as a $3.5 million seller note, payable in quarterly installments over two years.
	The allocation of the purchase price to the acquired assets and liabilities, based on management’s estimate of their fair values on the acquisition date, is as follows (in thousands):

	Cash used in acquisitions, net of cash acquired	$	14,282	$	452	$	62,762	$	29,412	$	106,908
	The acquisitions resulted in $101.3 million of goodwill based on management’s estimate on the acquisition closing dates, of which $100.3 million will be deductible for income tax purposes over 15 years.
	The net sales included in the Company’s condensed consolidated statement of operations derived from the Yotes, Southern Max, Sleep Experts and Mattress Liquidators acquisitions from the respective acquisition dates to July 29, 2014 were $12.8 million, $0.4 million, $24.2 million and $6.1 million, respectively.
	Acquisition-related costs for U.S. GAAP purposes are costs the acquirer incurs to effect a business combination, including advisory, legal, accounting, valuation, and other professional or consulting fees. The Company incurred a total of approximately $2.8 million and $4.4 million of acquisition-related costs charged to general and administrative expenses during the thirteen and twenty-six weeks ended July 29, 2014. See “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for an additional discussion of acquisition-related costs.
	The following table presents the selected consolidated financial information of the Company on a pro forma basis, assuming the acquisitions described above had occurred as of January 28, 2014.  The historical financial information has been adjusted to give effect to the pro forma items that are directly attributable to the acquisition and are expected to have a continuing impact on the consolidated results.
	The unaudited financial information set forth below has been compiled from the historical financial statements and other information, but is not necessarily indicative of the results that actually would have been achieved had the transactions occurred on the dates indicated or that may be achieved in the future (amounts in thousands, except per share amounts):
		Thirteen Weeks Ended July 29, 2014						Twenty-Six Weeks Ended July 29, 2014
		As Reported		Pro Forma Adjustments		Pro Forma		As Reported		Pro Forma Adjustments		Pro Forma
	Net sales	$	409,951	$	5,628	$	415,579	$	743,453	$	38,882	$	782,335

	Diluted net income per common share	$	0.41	$	0.01	$	0.42	$	0.64	$	0.01	$	0.65
	Goodwill represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The Company’s goodwill is primarily related to the increase in the Company’s store locations and market share with expectations of expense synergies and leverage over costs, such as advertising and warehousing.  The measurement periods for purchase price allocations end as soon as information on the facts and circumstances become available, but do not exceed 12 months.  Adjustments in purchase price allocations may require a recasting of the amounts allocated to goodwill.
	The Company is continuing to evaluate the fair values of the assets and liabilities acquired, and as a result, adjustments to the values presented above may be modified over the next several quarters. In the thirteen weeks ended April 29, 2014, the Company adjusted the deferred tax balance related to the fiscal 2013 acquisition of the assets and operations of Perfect Mattress of Wisconsin, LLC (“Perfect Mattress”) resulting in $0.6 million of additional goodwill. The Company is continuing to evaluate working capital adjustments, related to the Mattress Liquidators acquisition, which may impact the values presented above.
	A summary of the changes in the carrying amounts of goodwill for the twenty-six weeks ended July 29, 2014 is as follows (in thousands):
	Balance at January 28, 2014	$	366,647
	Prior year business acquisition adjustment		568

3. Fair Value of Financial Instruments

The amounts reported in the condensed consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their respective fair values due to the short-term maturity of these instruments.

The FASB has issued guidance on the definition of fair value, the framework for using fair value to measure assets and liabilities, and disclosure regarding fair value measurements. The guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value. These tiers include:

·

Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

·

Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market and contractual prices for the underlying instruments, as well as other relevant economic measures.

·

Level 3: Defined as pricing inputs that are unobservable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

The Company measures the fair value of its nonqualified deferred compensation plan on a recurring basis. The plan’s assets are valued based on the marketable securities tied to the plan. Additionally, the Company measures the fair values of goodwill, intangible assets, and property and equipment on a nonrecurring basis if required by impairment tests applicable to these assets. Assets requiring recurring or non-recurring fair value measurements consisted of the following (in thousands):

The significant Level 3 unobservable input used in the fair value measurement of the Company’s property and equipment was the weighted average cost of capital (“WACC”). Increases (decreases) in WACC inputs in isolation would result in a lower (higher) fair value measurement.

The following tables are not intended to be all-inclusive, but rather provide a summary of the significant unobservable inputs used in the fair value measurement of the Company’s Level 3 assets in which impairment testing was performed.

	2012 Senior Credit Facility—On January 18, 2007, Mattress Holding Corp., an indirect consolidated subsidiary of the Company, entered into a credit agreement with UBS Securities LLC and certain of its affiliates and other lenders for a senior secured term loan and revolving credit facility, which was amended and restated on November 5, 2012 and further amended on February 27, 2014 (as amended, the “2012 Senior Credit Facility”). The November 2012 amendment and restatement, among other things, (i) increased the revolving loan commitment from $35 million to $100 million, (ii) extended the maturity date of the revolving credit facility by two years to January 2015, (iii) extended the maturity date of outstanding term loans having an aggregate principal amount of $200 million by two years to January 2016 (“extended term loans”), (iv) increased the interest rate applicable to amounts outstanding under the extended term loans and revolving loans by 1.25%, (v) increased the amount of permitted capital expenditures to $80 million on an annual basis, beginning with capital expenditures incurred during fiscal 2012, and (vi) increased the maximum cumulative amount that Mattress Holding Corp. and its subsidiary guarantors may incur for permitted acquisitions through the extended maturity date.
	On February 27, 2014, the Company entered into an amendment of the 2012 Senior Credit Facility. The amendment, among other things, (a) extended the maturity date of the revolving loan by one year to January 2016, (b) increased the incremental term loan facility by $150 million to $200 million, which allowed for a total term loan facility of $400 million, (c) increased the maximum amount the borrower and its subsidiary guarantors may spend in respect of acquisitions, on a per acquisition basis, from $50 million to $75 million, and (d) increased the maximum amount the borrower and its subsidiary guarantors may spend in respect of acquisitions, on an aggregate basis, from $200 million to $350 million. The Company incurred fees in connection with the amendment of approximately $0.6 million, of which $0.2 million was expensed in the thirteen weeks ended April 29, 2014 and $0.4 million was capitalized and will be amortized over the term of the loan facility.
	Borrowings under the 2012 Senior Credit Facility bear interest at a rate equal to an applicable margin plus, at the Company’s operation, either (i) a base rate determined by reference to the highest of (a) the corporate base rate of interest established by the administrative agent and (b) the federal funds effective rate from time to time plus 0.50%, or (ii) the period relevant to such borrowing adjusted for certain additional costs. The applicable margin percentages for extended term loans are 2.50% for base rate loans and 3.50% for LIBOR loans. The applicable margin percentages for revolving loans are 2.50% for base rate loans and 3.50% for LIBOR loans. The weighted average interest rate applicable to outstanding borrowings under the 2012 Senior Credit Facility was 3.8% for both the twenty-six weeks ended July 30, 2013 and July 29, 2014.
	Outstanding term borrowings under the 2012 Senior Credit Facility are payable in quarterly principal installments of $0.8 million in fiscal 2014 and fiscal 2015. Accrued interest on outstanding borrowings is payable from time to time and no less frequently than quarterly.
	The revolving credit facility portion of the 2012 Senior Credit Facility provides Mattress Holding Corp. with up to $100.0 million in outstanding revolving borrowings, with up to $15.0 million of that amount available for the issuance of letters of credit. Outstanding revolving borrowings were $21.0 million and none at January 28, 2014 and July 29, 2014, respectively. Outstanding letters of credit on the revolving facility were $1.6 million at July 29, 2014, resulting in $98.4 million of availability for revolving borrowings and up to $13.4 million of that amount available for the issuance of letters of credit.
	The 2012 Senior Credit Facility, subject to certain exceptions, is guaranteed by Mattress Holding Corp.’s immediate parent entity, Mattress Holdco, Inc., and by each of the existing and future subsidiaries of Mattress Holding Corp. All obligations under the 2012 Senior Credit Facility, and the guarantees of those obligations, are secured by substantially all of the existing and future property and assets of Mattress Holding Corp. and the subsidiary guarantors under the 2012 Senior Credit Facility, and by a pledge of Mattress Holding Corp.’s capital stock and the capital stock of each of its subsidiary guarantors. Mattress Holding Corp. is subject to certain financial covenants under the agreement principally consisting of maximum debt leverage and minimum interest coverage ratios. Subject to certain restrictions, Mattress Holding Corp. has the ability to exercise equity cure rights, which allow the inclusion of capital contributions received from the Company in the results of operations for the purpose of measuring the maximum debt leverage and minimum interest coverage ratios. In addition, the 2012 Senior Credit Facility places limits on the amounts of annual capital expenditures and contains restrictions on certain transactions with affiliates; prepaying subordinated debt; incurring indebtedness and liens; declaring dividends or redeeming or repurchasing capital stock; making loans and investments; and engaging in mergers, acquisitions, consolidations and asset sales. Mattress Holding Corp. was in compliance with all financial covenants at July 29, 2014.
	Equipment Financing and Other Short-Term Notes Payable—A subsidiary of the Company has an outstanding note payable related to the purchase of mattress specialty retail stores formerly operated by our franchisee, Perfect Mattress, in the aggregate principal amount of $1.0 million that bears interest at 7.75% with quarterly principal and interest payments through fiscal 2014. A subsidiary of the Company has an outstanding note payable related to the purchase of mattress specialty retail stores formerly operated by Mattress Liquidators, in the aggregate principal amount of $3.4 million that bears interest at 6.00% with quarterly principal and interest payments through fiscal 2016.
	A subsidiary of the Company has financed property and casualty insurance premiums payable in the amount of $0.7 million payable in fiscal 2014.

	Income tax expense during interim periods is based on the estimated annual effective income tax rate plus any discrete items which are recorded in the period in which they occur. Discrete items include such events as changes in estimates due to the finalization of tax returns, tax audit settlements, tax law changes, and increases or decreases in valuation allowances related to prior year estimates. The determination of the consolidated provision for income taxes, deferred tax assets and liabilities and related valuation allowance requires management to make judgments and estimates. Although management believes that its tax estimates are reasonable, the ultimate tax determination involves significant judgments that could become subject to audit by tax authorities in the ordinary course of business, as well as the generation of sufficient future taxable income.
	The Company recognized $14.1 million of income tax expense for the twenty-six weeks ended July 29, 2014, compared to $16.6 million of income tax expense for the twenty-six weeks ended July 30, 2013. The effective tax rate was 39.0% for the twenty-six weeks ended July 29, 2014, compared to 38.9% for the twenty-six weeks ended July 30, 2013. The effective tax rate of 39.0% for the current period differs from the federal statutory rate of 35.0% primarily due to state income taxes.
	The Company and its subsidiaries are included in a consolidated income tax return in the U.S. federal jurisdiction and file separate income tax returns in several states. As of July 29, 2014, open tax years in federal and some state jurisdictions date back to October 2002 due to the taxing authorities’ ability to adjust operating loss carryforwards.
	As of January 28, 2014, the Company had approximately $9.1 million of net operating loss carryforwards that begin expiring in fiscal 2029, if not utilized to offset future taxable income. These net operating loss carryforwards arose from the acquisition of MGHC Holding Corporation (“Mattress Giant”) during fiscal 2012, and after application of Section 382 of the Internal Revenue Code of 1986, as amended, are limited to an average use of $2.8 million per year over the next four years.
	The Company has established a cumulative liability for unrecognized tax benefits of $0.4 million as of July 29, 2014 and January 28, 2014. Management does not anticipate there will be a material change in the total amount of unrecognized tax benefits within the next twelve months. Management accrued less than $0.1 million of interest on these unrecognized tax benefits as of July 29, 2014.

	6. Earnings Per Share
	Basic net income per common share is computed by dividing the net income applicable to common shares by the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period, adjusted to reflect potentially dilutive securities using the treasury stock method for stock option awards. Diluted net income per common share adjusts basic net income per common share for the effects of stock options and other potentially dilutive financial instruments only in the periods in which such effect is dilutive.
	The following table presents a reconciliation of the weighted average shares outstanding used in the earnings per share calculations:
		Thirteen Weeks Ended				Twenty-Six Weeks Ended
		July 30,		July 29,			July 30,	July 29,
		2013		2014			2013	2014
	Basic weighted average shares outstanding		33,853,733		34,135,060		33,832,928		34,081,500
	Effect of dilutive securities:
	Stock options		248,451		321,740		206,826		321,054
	Restricted shares		47,456		66,820		36,813		61,484
	Diluted weighted average shares outstanding		34,149,640		34,523,620		34,076,567		34,464,038
	Diluted net income per common share for the thirteen and twenty-six weeks ended July 29, 2014, excludes stock options for the purchase of 117,337 and 120,837 shares of common stock, respectively, as their inclusion would be anti-dilutive. Diluted net income per common share for the thirteen and twenty-six weeks ended July 30, 2013, excludes stock options for the purchase of 232,004 shares of common stock as their inclusion would be anti-dilutive.
	Certain stock option and restricted stock awards contain vesting conditions based on specified stock price targets for the Company’s common stock as measured at each of the annual vesting dates (“market-based awards”). The Company includes such market-based awards in the determination of dilutive weighted average shares outstanding under the treasury stock method when, as of the date of determination, the specified stock price targets are met and the common stock shares pursuant to those awards become contingently issuable. Accordingly, the determination of diluted weighted average shares outstanding excludes, as of the date of determination, stock options for the purchase of 13,276 and 141,687 shares of common stock for the thirteen and twenty-six weeks ended July 29, 2014 and July 30, 2013, respectively, and excludes 48,990 shares of non-vested restricted stock for the thirteen and twenty-six weeks ended July 29, 2014.

	The Company conducts the majority of its operations from leased store and warehouse facilities pursuant to non-cancellable operating lease agreements with initial terms general ranging from 1 to 15 years. Certain leases include renewal options generally ranging from one to five years and contain certain rent escalation clauses. Most leases require the Company to pay its proportionate share of the property tax, insurance and maintenance expenses of the property. Certain leases provide for contingent rentals based on sales volume: however, incremental rent expense resulting from such arrangements are accrued for those stores expected to surpass the sales threshold subject to their respective lease agreements.
	The Company is subject to legal proceedings and claims that arise in the ordinary course of business. Management does not believe that the outcome of any of those matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows.

	2011 Omnibus Incentive Plan—On November 3, 2011, the Company’s board of directors and shareholders adopted the Mattress Firm Holding Corp. 2011 Omnibus Incentive Plan to provide for the grant of equity-based awards to Company employees, directors and other service providers. A total of 4,206,000 shares of the Company’s common stock were reserved for grants under the 2011 Omnibus Incentive Plan. There were 2,568,039 shares available for future grants under the stock incentive plan as of July 29, 2014.
	Stock Options—A portion of the stock options granted to the Company’s employees are subject to time-based vesting schedules, while the remaining portion of the stock options are subject to market-based vesting schedules, with such vesting based on specified stock price targets. The exercise price of the options is based upon the closing market price per share of the Company’s common stock on the date of grant, and the options have a term of 10 years.
	The following table summarizes the stock option grants, exercises, and forfeitures for the twenty-six weeks ended July 29, 2014 (in thousands, except per share amounts):
					Weighted
					Average
			Stock		Exercise Price

	Exercisable, as of July 29, 2014 (d)		298		$	20.14
		(a)		The weighted average grant date fair value of stock options granted during the twenty-six weeks ended July 29, 2014 was $26.13.
		(b)		The aggregate intrinsic value of stock options exercised during the twenty-six weeks ended July 29, 2014 was $2.3 million. The weighted average market price of shares exercised during the twenty-six weeks ended July 29, 2014 was $46.97.
		(c)		Stock options outstanding as of July 29, 2014 have a weighted average remaining contractual term of 7.42 years and an aggregate intrinsic value of $27.3 million based on the market value of the Company’s common stock on July 29, 2014.
		(d)		Stock options exercisable as of July 29, 2014 have a weighted average remaining contractual term of 7.17 years and an aggregate intrinsic value of $8.2 million based on the market value of the Company’s common stock on July 29, 2014.
	Future vesting dates on the stock options range from August 13, 2014 to April 29, 2018, and expiration dates range from November 17, 2021 to April 29, 2024 at exercise prices and average contractual lives as follows:
	Range of Exercise Prices		Outstanding as of July 29, 2014 (in thousands)			Weighted Average Remaining Contractual Life (in years)	Weighted Average Exercise Price		Exercisable as of July 29, 2014 (in thousands)	Weighted Average Remaining Contractual Life (in years)	Weighted Average Exercise Price

	$36.84 - $45.37		22			7.00	$	36.84	9	4.39	$	36.84
	The Company accounts for employee stock options under the fair value method of accounting using a Black Scholes methodology to measure time based option fair value at the date of grant and a Monte Carlo Simulation approach to measure market-based option fair value at the date of grant. The fair value of the stock options at the date of grant is recognized as expense over the vesting term, which represents the requisite service period.
	The following assumptions were used to calculate the fair value of the Company’s time-based stock options on the date of grant utilizing the Black- Scholes option pricing model:
			Twenty‑Six Weeks
			Ended
			July 29, 2014
	Weighted average expected life (in years)		6.25
	Volatility factor		60	%
	Dividend yield		0	%
	Risk-free interest rate		2.08	%
	The Company bases its expected option life on the expected exercise and termination behavior of the option holders and an appropriate model of the Company’s future stock price. The expected volatility assumption is derived from the historical volatility of similar companies’ common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options, combined with other relevant factors. The dividend yield is the annual rate of dividends per share over the exercise price of the option as of the grant date.
	For the thirteen and twenty-six weeks ended July 29, 2014, the Company recognized $0.4 million and $1.2 million, respectively, of compensation expense associated with stock option awards in general and administrative expenses in the consolidated statement of operations compared to $0.7 million and $1.2 million for the thirteen and twenty-six weeks ended July 30, 2013, respectively. The Company did not capitalize any equity-based compensation costs related to stock options during the thirteen and twenty-six weeks ended July 29, 2014 and July 30, 2013.
	As of July 29, 2014, the Company estimates that a total of approximately $5.7 million of currently unrecognized forfeiture adjusted compensation expense will be recognized over a weighted average period of 2.33 years for unvested stock option awards issued and outstanding.
	Restricted Stock—The Company grants restricted stock to certain employees and to non-employee independent directors. A portion of the restricted stock granted to the Company’s employees is subject to time-based vesting schedules, while the remaining portion of the restricted stock is subject to market-based vesting schedules, with such vesting based on specified stock price targets.
	The following table summarizes the restricted stock grants, vesting, and forfeitures for the twenty-six weeks ended July 29, 2014 (in thousands, except per share amounts):
					Weighted
					Average
			Restricted		Fair
			Shares		Value
	Outstanding, as of January 28, 2014		249		$	29.93
	Granted (a)		10		$	37.83
	Vested (b)		-14		$	32.65
	Forfeited		-14		$	24.68
	Unvested, as of July 29, 2014		231		$	30.44
		(a)		The total grant-date fair value of restricted stock awards granted during the period was $0.4 million.
		(b)		The total fair value of awards vested during the twenty-six weeks ended July 29, 2014 was $0.6 million.
	The Company accounts for restricted stock under the fair value method of accounting using the closing market price per share of the Company’s stock to measure time based restricted stock fair value at the date of grant and a Monte Carlo Simulation approach to measure market-based restricted stock fair value at the date of grant. The fair value of the restricted stock at the date of grant is recognized as expense over the vesting term, which represents the requisite service period.
	The following assumptions were used to calculate the fair value of the Company’s market-based restricted stock on the grant date utilizing a Monte Carlo Simulation approach:
			Twenty‑Six Weeks
			Ended
			July 29, 2014
	Weighted average expected life (in years)		4
	Volatility factor		40	%
	Dividend yield		0	%
	Risk-free interest rate		1.33	%
	For the thirteen and twenty-six weeks ended July 29, 2014, the Company recognized $0.8 million and $1.4 million, respectively, of compensation expense associated with restricted stock awards in general and administrative expenses in the condensed consolidated statement of operations compared to $0.3 million and $0.7 million for the thirteen and twenty-six weeks ended July 30, 2013, respectively. The Company did not capitalize any equity-based compensation costs related to restricted stock awards during the thirteen and twenty-six weeks ended July 29, 2014 and July 30, 2013.
	As of July 29, 2014, the Company estimates that a total of approximately $5.2 million of currently unrecognized forfeiture adjusted compensation expense will be recognized over a weighted average period of 2.07 years for unvested restricted stock awards.
