	BASIS OF PRESENTATION
	Chuy’s Holdings, Inc. (the “Company” or “Chuy’s”) is in the business of developing and operating Chuy’s restaurants throughout the United States. Chuy’s is a fast-growing, full-service restaurant concept offering a distinct menu of authentic, freshly-prepared Mexican and Tex Mex inspired food. As of September 29, 2013, the Company operated 46 restaurants in thirteen states.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements and the related notes reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods presented. The financial statements have been prepared in accordance with Generally Accepted Accounting Principles (“GAAP”), except that certain information and notes have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (the “SEC”). Results for interim periods are not necessarily indicative of the results that may be expected for the full fiscal year. The unaudited condensed consolidated financial statements should be read in conjunction with consolidated financial statements and notes included in the Company’s annual report on Form 10-K for the fiscal year ended December 30, 2012.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ from those estimates.
	Certain prior period amounts were reclassified to conform to the 2013 presentation. These reclassifications had no impact on net income or total equity.
	The Company operates on a 52- or 53- week fiscal year that ends on the last Sunday of the calendar year. Each quarterly period has 13 weeks, except for a 53-week year when the fourth quarter has 14 weeks. Our 2012 fiscal year consisted of 53 weeks and our 2013 fiscal year will consist of 52 weeks.
	On January 30, 2013, a secondary offering of the Company’s common stock was completed by certain of the Company’s existing stockholders. The selling stockholders sold 5,175,000 previously outstanding shares, including 675,000 shares sold pursuant to the full exercise of the underwriters’ option to purchase additional shares.
	On April 17, 2013, a secondary offering of the Company's common stock was completed by certain of the Company's existing stockholders. The selling stockholders sold 3,000,000 previously outstanding shares. In addition, the underwriters exercised their option to purchase an additional 257,113 shares of common stock from the selling stockholders.
	The Company did not receive any proceeds from these two offerings. The selling stockholders paid all of the underwriting discounts and commissions associated with the sale of the shares; however, the Company incurred approximately $1.2 million in costs and registration expenses related to the offerings, of which $925,000 was incurred during the thirty-nine weeks ended September 29, 2013.

	In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") number 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists — a consensus of the FASB Emerging Issues Task Force. ASU 2013-11 generally requires, with some exceptions, an entity to present its unrecognized tax benefits as it relates to its net operating loss carryforwards, similar tax losses, or tax credit carryforwards, as a reduction of deferred tax assets when settlement is available under the tax law of the applicable taxing jurisdiction as of the balance sheet reporting date. It is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Retrospective application is permitted. The Company does not anticipate a material impact on its financial position, results of operations or cash flows as a result of this change.

Earnings Per Share	'
	EARNINGS PER SHARE
	The number of shares and earnings per share (“EPS”) data for all periods presented are based on the historical weighted-average shares of common stock outstanding. EPS for the thirteen weeks and thirty-nine weeks ended September 23, 2012 is computed using the two-class method. The two-class method determines EPS for common stock and participating securities according to dividends and dividend equivalents and their respective participation rights in undistributed earnings. The Company’s convertible preferred stockholders were entitled to receive dividends in the event dividends on the Company’s common stock were declared. As a result, the shares of the Company’s convertible preferred stock were deemed to be participating securities.
	In connection with the Company's initial public offering (“IPO”), in July of 2012, all shares of series A preferred stock, series B preferred stock and series X preferred stock were converted into common stock.
	Basic EPS of the Company's common stock is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period.
	Diluted EPS of the Company's common stock is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential shares of common stock equivalents outstanding during the period using the treasury stock method for dilutive options and the if converted method for convertible preferred stock.
	The computation of basic and diluted earnings per share is as follows:

	STOCK-BASED COMPENSATION
	The Company has outstanding awards under the 2006 Plan. The outstanding options vest 20% on each of the first five anniversaries of the date of grant and have a maximum term of 10 years. In connection with the IPO, the Company terminated the 2006 Plan, and no further awards will be granted under the 2006 Plan. The termination of the 2006 Plan did not affect awards outstanding under the 2006 Plan at the time of its termination and the terms of the 2006 Plan continue to govern those outstanding awards.
	In connection with the IPO, the Company adopted the 2012 Omnibus Equity Incentive Plan (the “2012 Plan”) which allows the Company’s Board of Directors to grant stock options, restricted stock, and other equity-based awards to directors, officers, and key employees of the Company. The 2012 Plan provides for granting of options to purchase shares of common stock at an exercise price not less than the fair value of the stock on the date of grant. The outstanding options vest 20% on each of the first five anniversaries of the date of grant and have a maximum term of 10 years. As of September 29, 2013, a total of 1,080,120 shares of common stock are reserved and remain available for issuance under the 2012 Plan.
	Stock-based compensation cost recognized in the accompanying consolidated income statements was $147,000 and $77,000 for the thirteen weeks ended September 29, 2013 and September 23, 2012, respectively, and $383,000 and $252,000 for the thirty-nine weeks ended September 29, 2013 and September 23, 2012, respectively.
	A summary of stock-based compensation activity and changes for the thirty-nine weeks ended September 29, 2013 are as follows:
		Shares		Weighted		Weighted	Aggregate
				Average		Average	Intrinsic
				Exercise		Remaining	Value
				Price		Contractual
						Term
						(Year)
	Outstanding and expected to vest at December 30, 2012	1,052,861		$	5.28
	Granted	145,907		28.97
	Exercised	(463,613	)	3.07
	Forfeited	(2,702	)	12.18
	Outstanding and expected to vest at September 29, 2013	732,453		$	11.37	5.73	$	16,757
	Exercisable at September 29, 2013	467,978		$	5.6	4.47	$	13,406
	The aggregate intrinsic value in the table above is obtained by subtracting the weighted average exercise price from the estimated fair value of the underlying common stock as of September 29, 2013 and multiplying this result by the related number of options outstanding and exercisable at September 29, 2013. The estimated fair value of the common stock as of September 29, 2013 used in the above calculation was $34.25 per share, the closing price of the Company’s common stock on September 27, 2013, the last trading day of the third quarter.
	The weighted-average grant date fair value of options granted during the thirty-nine weeks ended September 29, 2013 was $11.02 per share, as estimated at the date of grant using the Black-Scholes pricing model with the following weighted-average assumptions:
	Dividend yield	0	%
	Expected volatility	43	%
	Risk-free rate of return	0.79	%
	Expected life (in years)	5
	The assumptions above represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management’s judgment. The expected term of options granted is based on a representative peer group with similar employee groups and expected behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury constant maturities rate in effect at the time of grant. The Company utilized a weighted rate for expected volatility based on a representative peer group within the industry.
	There was approximately $2.0 million of total unrecognized compensation costs related to options granted under the 2006 Plan and the 2012 Plan as of September 29, 2013. These costs will be recognized ratably through the year 2018. In the event of a change of control, approximately $428,000 of the Company’s unrecognized compensation costs would be immediately recognized.

	LONG-TERM DEBT
	Revolving Credit Facility
	On November 30, 2012, the Company entered into a secured $25 million revolving credit facility (the “Revolving Credit Facility”) with Wells Fargo Bank, National Association, which replaced the Company's previous credit facility. The Revolving Credit Facility (a) will mature on November 30, 2017, unless the Company exercises its option to voluntarily reduce all of the commitment before the maturity date, (b) accrues commitment fees on the daily unused balance of the facility at an applicable margin, which varies based on the Company’s consolidated total lease adjusted leverage ratio and (c) provides for letters of credit in amounts totaling the lesser of $5 million or the available borrowings under our Revolving Credit Facility. All borrowings under the Revolving Credit Facility bear interest at a variable rate based upon the Company’s election, of (i) the base rate (which is the highest of the prime rate, federal funds rate plus 0.50% or one month LIBOR) plus 1%, or (ii) LIBOR, plus, in either case, an applicable margin based on the Company’s consolidated total lease adjusted leverage ratio. Interest is due at the end of each quarter if the Company selects to pay interest based on the base rate and at the end of each LIBOR period if it selects to pay interest based on LIBOR. The Company has elected a variable rate of interest based on LIBOR. As of September 29, 2013, this interest rate was 1.94%.
	As a result of entering into the Revolving Credit Facility, the Company paid loan origination costs of approximately $216,000 related to the Revolving Credit Facility, and will amortize these loan origination costs over the term of the credit agreement.
	The obligations under the Company’s long-term debt are secured by a first priority lien on substantially all of the Company’s assets.
	The Revolving Credit Facility requires the Company to comply with certain financial covenants including leverage ratios, fixed charge ratios, capital expenditures as well as other customary affirmative and negative covenants. As of September 29, 2013, the Company was in compliance with all covenants under the Revolving Credit Facility.

	INCOME TAXES
	The effective income tax rate for the thirty-nine weeks ended September 29, 2013 was 28.2% compared to an effective income tax rate of 30.0% for the thirty-nine weeks ended September 23, 2012. The decrease in the effective income tax rate from the prior year was primarily attributable to the favorable impact of a one time adjustment made for incremental employment tax credits for the current year as well as the previous open tax years, which resulted in a $556,000 net favorable impact in net income during the thirty-nine weeks ended September 29, 2013. The decrease in the effective income tax rate was partially offset by the unfavorable impact of the non-tax deductible secondary offering costs incurred during the current thirty-nine weeks ended September 29, 2013. The impact on the effective income tax rate for these items will be treated discretely in this thirty-nine week period as required by the FASB's Accounting Standards Codification. The effective income tax rate for 2013 excluding these discrete items is estimated to be approximately 30%.
	Since the Company has net operating loss carry forwards, the net favorable tax benefit mentioned above will primarily increase the general business credits deferred tax asset.
