Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Business Description. Fiesta Restaurant Group, Inc. ("Fiesta Restaurant Group" or "Fiesta") owns, operates and franchises two restaurant brands through its wholly-owned subsidiaries Pollo Operations, Inc. and its subsidiaries, Pollo Franchise, Inc. (collectively “Pollo Tropical”) and Taco Cabana, Inc. and its subsidiaries (collectively “Taco Cabana”). Unless the context otherwise requires, Fiesta and its subsidiaries, Pollo Tropical and Taco Cabana, are collectively referred to as the “Company”. At July 1, 2018 , the Company owned and operated 150 Pollo Tropical ® restaurants and 170 Taco Cabana ® restaurants. The Pollo Tropical restaurants included 141 located in Florida and 9 located in Georgia. All of the Taco Cabana restaurants are located in Texas. At July 1, 2018 , the Company franchised a total of 30 Pollo Tropical restaurants and eight Taco Cabana restaurants. The franchised Pollo Tropical restaurants included 17 in Puerto Rico, four in Panama, two in Guyana, one in the Bahamas, and six on college campuses and at a hospital in Florida. The franchised Taco Cabana restaurants included six in New Mexico and two on college campuses in Texas. Basis of Consolidation. The unaudited condensed consolidated financial statements presented herein reflect the consolidated financial position, results of operations and cash flows of Fiesta and its wholly-owned subsidiaries. All intercompany transactions have been eliminated in consolidation. Fiscal Year . The Company uses a 52 - 53 week fiscal year ending on the Sunday closest to December 31. The fiscal year ended December 31, 2017 contained 52 weeks. The three and six months ended July 1, 2018 and July 2, 2017 each contained thirteen and twenty-six weeks, respectively. The fiscal year ending December 30, 2018 will contain 52 weeks. Basis of Presentation. The accompanying unaudited condensed consolidated financial statements for the three and six months ended July 1, 2018 and July 2, 2017 have been prepared without an audit pursuant to the rules and regulations of the Securities and Exchange Commission and do not include certain information and footnotes required by U.S. Generally Accepted Accounting Principles ("GAAP") for complete financial statements. In the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation of such financial statements have been included. The results of operations for the three and six months ended July 1, 2018 and July 2, 2017 are not necessarily indicative of the results to be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2017 included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . The December 31, 2017 balance sheet data is derived from those audited financial statements. Reclassification. Write-offs of site development costs were reclassified from general and administrative expense to other expense (income), net in the condensed consolidated statement of operations to conform with the current year presentation. Guidance Adopted in 2018. In May 2014, and in subsequent updates, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the guidance in former Topic 605, Revenue Recognition, and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company adopted this new accounting standard and all the related amendments as of January 1, 2018 using the modified retrospective method, and recognized a total cumulative effect adjustment to increase retained earnings by less than $0.1 million , which consisted of a $0.3 million increase related to gift card breakage and a $0.3 million decrease related to initial franchise and area development fees, as a result of adopting the standard. The new standard did not impact the Company’s recognition of revenue from Company-owned and operated restaurants or its recognition of sale-based royalties from restaurants operated by franchisees. The comparative period information has not been restated and continues to be reported under the accounting standard in effect for those periods. When compared to the previous accounting policies, the impact of adopting the new standard was immaterial to current and long-term other liabilities and retained earnings at January 1, 2018 and to net income for the three and six months ended July 1, 2018 . The adoption of the new standard had no impact on the Company's consolidated statements of cash flows. Revenue Recognition. Revenue is recognized upon transfer of promised products or services to customers in an amount that reflects the consideration the Company received in exchange for those products or services. Revenues from the Company's owned and operated restaurants are recognized when payment is tendered at the time of sale. Franchise royalty revenues are based on a percent of gross sales and are recorded as income when earned. Initial franchise fees and area development fees associated with new franchise agreements are not distinct from the continuing rights and services offered by the Company during the term of the related franchise agreements and are recognized as income over the term of the related franchise agreements. A portion of the initial franchise fee is allocated to training services and is recognized as revenue when the Company completes the training services. Prior to adopting Topic 606, the Company recognized initial franchise fees as revenue in the period that a franchised location opened for business. See Note 6 - Business Segment Information. Gift cards . The Company sells gift cards to its customers in its restaurants and through select third parties. The Company recognizes revenue from gift cards upon redemption by the customer. For unredeemed gift cards that the Company expects to be entitled to breakage, the Company recognizes expected breakage as revenue in proportion to the pattern of redemption by the customers. The gift cards have no stated expiration dates. Revenues from unredeemed gift cards and gift card liabilities, which are recorded in other current liabilities, are not material to the Company's financial statements. Prior to adopting Topic 606, the Company did not recognize breakage on its gift cards. Fair Value of Financial Instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. In determining fair value, the accounting standards establish a three level hierarchy for inputs used in measuring fair value as follows: Level 1 inputs are quoted prices in active markets for identical assets or liabilities; Level 2 inputs are observable for the asset or liability, either directly or indirectly, including quoted prices in active markets for similar assets or liabilities; and Level 3 inputs are unobservable and reflect our own assumptions. The following methods were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate the fair value: • Current Assets and Liabilities. The carrying values reported on the balance sheet of cash, accounts receivable and accounts payable approximate fair value because of the short maturity of those financial instruments. • Revolving Credit Borrowings. The fair value of outstanding revolving credit borrowings under the Company's senior credit facility, which is considered Level 2, is based on current LIBOR rates. The fair value of the Company's senior credit facility was approximately $72.8 million at July 1, 2018 , and $75.0 million at December 31, 2017 . The carrying value of the Company's senior credit facility was $73.0 million at July 1, 2018 and $ 75.0 million at December 31, 2017 . Long-Lived Assets . The Company assesses the recoverability of property and equipment and definite-lived intangible assets by determining whether the carrying value of these assets can be recovered over their respective remaining lives through undiscounted future operating cash flows. Impairment is reviewed when events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. See Note 3 - Impairment of Long-Lived Assets.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets and Other Lease Charges	6 Months Ended
	Jul. 01, 2018
Property, Plant and Equipment [Abstract]
Impairment of Long-Lived Assets and Other Lease Charges	Impairment of Long-Lived Assets and Other Lease Charges The Company reviews its long-lived assets, principally property and equipment, for impairment at the restaurant level. In addition to considering management’s plans, known regulatory or governmental actions and damage due to acts of God (hurricanes, tornadoes, etc.), the Company considers a triggering event to have occurred related to a specific restaurant if the restaurant’s cash flows for the last twelve months are less than a minimum threshold or if consistent levels of cash flows for the remaining lease period are less than the carrying value of the restaurant’s assets. If an indicator of impairment exists for any of its assets, an estimate of undiscounted future cash flows over the life of the primary asset for each restaurant is compared to that long-lived asset’s carrying value. If the carrying value is greater than the undiscounted cash flow, the Company then determines the fair value of the asset and if an asset is determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value. There is uncertainty in the projected undiscounted future cash flows used in the Company's impairment review analysis. If actual performance does not achieve the projections, the Company may recognize impairment charges in future periods, and such charges could be material. For closed restaurant locations, the Company reviews the future minimum lease payments and related ancillary costs from the date of the restaurant closure to the end of the remaining lease term and records a lease charge for the lease liabilities to be incurred, net of any estimated sublease recoveries. There is uncertainty in the estimates of future lease costs and sublease recoveries. Actual costs and sublease recoveries could vary significantly from the estimated amounts and result in additional lease charges or recoveries, and such amounts could be material. A summary of impairment on long-lived assets and other lease charges (recoveries) recorded by segment is as follows: Three Months Ended Six Months Ended July 1, 2018 July 2, 2017 July 1, 2018 July 2, 2017 Pollo Tropical $ 686 $ 10,536 $ 144 $ 42,607 Taco Cabana 98 226 (22 ) 569 $ 784 $ 10,762 $ 122 $ 43,176 Impairment and other lease charges for the three and six months ended July 1, 2018 primarily include lease charges, net of recoveries, of $0.5 million related to certain previously closed restaurants due to adjustments to estimates of future lease costs and impairment charges of $0.3 million related to previously closed restaurants as well as one underperforming Taco Cabana restaurant with a short remaining lease term. Impairment and other lease charges for the six months ended July 1, 2018 also include a net benefit of $(0.7) million in lease charge recoveries due primarily to a lease termination, a lease assignment, subleases and other adjustments to estimates of future lease costs in the first quarter of 2018. In conjunction with the Strategic Renewal Plan to drive long-term shareholder value creation, Pollo Tropical recognized impairment charges of $3.8 million and $35.7 million , and other lease charges, net of recoveries, of $6.7 million and $6.9 million for the three and six months ended July 2, 2017 , respectively. These charges were due primarily to impairment and closures of underperforming Pollo Tropical restaurants in the first and second quarters of 2017. Impairment and other lease charges for the three and six months ended July 2, 2017 for Taco Cabana consist of impairment charges of $0.2 million and $0.6 million , respectively. The Company determined the fair value of restaurant equipment, for those restaurants reviewed for impairment, based on current economic conditions, the Company’s history of using these assets in the operation of its business and the Company's expectation of how a market participant would value the assets. In addition, for those restaurants reviewed for impairment where the Company owns the land and building, the Company utilized third-party information such as a broker quoted value to determine the fair value of the property. These fair value asset measurements rely on significant unobservable inputs and are considered Level 3 in the fair value hierarchy. The Level 3 assets measured at fair value associated with impairment charges recorded during the six months ended July 2, 2017 totaled $9.5 million

If the specified target stock price condition for any tranche is not met for the year, the cumulative unearned units will be rolled over to subsequent tranches on a pro rata basis. For the restricted stock units granted to executives in the six months ended July 1, 2018 and July 2, 2017 , the number of shares into which these restricted stock units convert ranges from no shares, if the service and market performance conditions are not met, to 112,169 and 92,171 shares, respectively, if the service and market performance conditions are met in the last vesting period. The weighted average fair value at grant date for the restricted stock units granted to executives in the six months ended July 1, 2018 and July 2, 2017 was $6.96 and $12.13 per share, respectively. During the six months ended July 2, 2017 , the Company granted certain employees a total of 11,745 restricted stock units under the Fiesta Plan. The restricted stock units granted during the six months ended July 2, 2017 vest and become non-forfeitable at the end of a four year vesting period. The weighted average fair value at grant date for these restricted stock units issued to employees during the six months ended July 2, 2017 was $20.75 per share. Stock-based compensation expense for the three and six months ended July 1, 2018 was $1.0 million and $1.9 million , respectively, and for the three and six months ended July 2, 2017 was $1.2 million and $1.8 million , respectively. At July 1, 2018 , the total unrecognized stock-based compensation expense related to non-vested restricted shares and restricted stock units was approximately $ 6.8 million . At July 1, 2018 , the remaining weighted average vesting period for non-vested restricted shares was 2.9 years and restricted stock units was 1.6 years. A summary of all non-vested restricted shares and restricted stock units activity for the six months ended July 1, 2018 is as follows: Non-Vested Shares Restricted Stock Units Shares Weighted Units Weighted Outstanding at December 31, 2017 239,500 $ 24.81 143,946 $ 23.11 Granted 187,747 19.02 112,169 6.96 Vested/Released (104,842 ) 25.63 (10,218 ) 45.67 Forfeited (17,037 ) 24.53 (12,243 ) 55.60 Outstanding at July 1, 2018 305,368 $ 20.61 233,654 $ 12.67

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information The Company owns, operates and franchises two restaurant brands, Pollo Tropical ® and Taco Cabana ® , each of which is an operating segment. Pollo Tropical restaurants feature 24-hour citrus marinated chicken and other freshly prepared tropical inspired menu items, while Taco Cabana restaurants specialize in Mexican inspired food. Each segment's accounting policies are described in the summary of significant accounting policies in Note 1 to the Company's audited financial statements contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . The primary measure of segment profit or loss used by the chief operating decision maker to assess performance and allocate resources is Adjusted EBITDA, which is defined as earnings attributable to the applicable operating segments before interest expense, income taxes, depreciation and amortization, impairment and other lease charges, stock-compensation expense, other expense (income), net, and certain significant items for each segment that management believes are related to strategic changes and/or are not related to the ongoing operation of the Company's restaurants as set forth in the reconciliation table below. The “Other” column includes corporate-related items not allocated to reportable segments and consists primarily of corporate-owned property and equipment, miscellaneous prepaid costs, capitalized costs associated with the issuance of indebtedness, corporate cash accounts and a current income tax receivable.

Earnings Per Share [Abstract]
Net Income (Loss) per Share	Net Income (Loss) per Share The Company computes basic net income (loss) per share by dividing net income (loss) applicable to common shares by the weighted average number of common shares outstanding during each period. Our non-vested restricted shares contain a non-forfeitable right to receive dividends on a one-to-one per share ratio to common shares and are thus considered participating securities. The impact of the participating securities is included in the computation of basic net income per share pursuant to the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings attributable to common shares and participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Net income per common share is computed by dividing undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and non-vested restricted shares based on the weighted average shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if our restricted stock units were to be converted into common shares. Restricted stock units with performance conditions are only included in the diluted earnings per share calculation to the extent that performance conditions have been met at the measurement date. We compute diluted earnings per share by adjusting the basic weighted average number of common shares by the dilutive effect of the restricted stock units, determined using the treasury stock method. Weighted average outstanding restricted stock units totaling 611 and 836 shares were not included in the computation of diluted earnings per share for the three and six months ended July 1, 2018 because including them would have been antidilutive. For the three and six months ended July 2, 2017 , all restricted stock units outstanding were excluded from the computation of diluted earnings per share because including them would have been antidilutive as a result of the net loss in these periods. The computation of basic and diluted net income (loss) per share is as follows: Three Months Ended Six Months Ended July 1, 2018 July 2, 2017 July 1, 2018 July 2, 2017 Basic and diluted net income (loss) per share: Net income (loss) $ 9,493 $ (2,160 ) $ 13,677 $ (17,220 ) Less: income allocated to participating securities 113 — 148 — Net income (loss) available to common shareholders $ 9,380 $ (2,160 ) $ 13,529 $ (17,220 ) Weighted average common shares, basic 26,916,295 26,815,015 26,895,302 26,794,560 Restricted stock units 3,619 — 6,527 — Weighted average common shares, diluted 26,919,914 26,815,015 26,901,829 26,794,560 Basic net income (loss) per share $ 0.35 $ (0.08 ) $ 0.50 $ (0.64 ) Diluted net income (loss) per share $ 0.35 $ (0.08 ) $ 0.50 $ (0.64 )

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Lease Assignments . Taco Cabana has assigned three leases to various parties on properties where it no longer operates restaurants with lease terms expiring on various dates through 2029. The assignees are responsible for making the payments required by the leases. The Company is a guarantor under one of the leases, and it remains secondarily liable as a surety with respect to two of the leases. Pollo Tropical assigned one lease to a third party on a property where it no longer operates with a lease term expiring in 2033. The assignee is responsible for making the payments required by the lease. The Company is a guarantor under the lease. The maximum potential liability for future rental payments that the Company could be required to make under these leases at July 1, 2018 was $3.8 million . The Company could also be obligated to pay property taxes and other lease related costs. The obligations under these leases will generally continue to decrease over time as the operating leases expire. The Company does not believe it is probable that it will be ultimately responsible for the obligations under these leases. Legal Matters . On November 24, 2015, Pollo Tropical received a legal demand letter alleging that assistant managers were misclassified as exempt from overtime wages under the Fair Labor Standards Act. On September 30, 2016, prior to any suit being filed, Pollo Tropical reached a settlement with seven named individuals and a proposed collective action class that allowed current and former assistant managers to receive notice and opt-in to the settlement. Pollo Tropical denies any liability or unlawful conduct. The settlement was approved by a Florida state judge on December 27, 2017 which resulted in dismissal with prejudice for the named individuals and all individuals that opted-in to the settlement. The Company reserved $0.8 million in 2016 to cover the estimated costs related to the settlement. During the second quarter of 2018, the Company paid all settlement claims costs and recognized a reduction in legal settlement costs of $0.2 million . The Company is also a party to various other litigation matters incidental to the conduct of business. The Company does not believe that the outcome of any of these matters will have a material effect on its consolidated financial statements. Contingency Related to Insurance Recoveries. During the third quarter of 2017, Texas and Florida were struck by Hurricanes Harvey and Irma (the "Hurricanes"). Over 40 Taco Cabana restaurants in the Houston metropolitan area and all Pollo Tropical restaurants in Florida and the Atlanta metropolitan area were temporarily closed and affected by the Hurricanes to varying degrees (e.g. property preparation and damages, inventory losses, payments to hourly employees while restaurants were closed and lost business related to temporary closures). In 2017, the Company recorded certain expected insurance proceeds in accounts receivable of $0.7 million and $0.4 million for Pollo Tropical and Taco Cabana, respectively. During the second quarter of 2018, the Company received property damage insurance proceeds of $0.4 million related to a Taco Cabana restaurant that suffered flood damages due to Hurricane Harvey. In late June 2018, the Company reached written settlement agreements with an insurance carrier for $2.5 million and $1.0 million for Pollo Tropical and Taco Cabana, respectively, for partial settlement related primarily to business interruption coverage. As a result, the Company recorded the additional expected insurance proceeds in accounts receivable with corresponding increases to other income of $1.8 million and $1.0 million

Income Taxes	Income Taxes Tax Law Changes. On December 22, 2017, the Tax Cuts and Jobs Act (the "Act"), which includes a provision that reduces the federal corporate income tax rate from 35.0% to 21.0% effective January 1, 2018, was signed into law. In accordance with generally accepted accounting principles, the enactment of this new tax legislation required the Company to revalue its net deferred income tax assets at the new corporate statutory rate of 21.0% as of the enactment date, which resulted in a one-time adjustment to its deferred income taxes of $9.0 million with a corresponding increase to the provision for income taxes as a discrete item during the fourth quarter of 2017. On December 22, 2017, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (SAB 118), which provides guidance on accounting for the impact of the Act, that, in effect, allows entities to use a methodology similar to the measurement period in a business combination. Pursuant to the disclosure provisions of SAB 118, the Company continues to evaluate the impact of the Act on various matters. The actual impact of the Act on the Company may differ from the provisional amounts recognized based on its reasonable estimates due to, among other things, changes in assumptions made in the Company's interpretation of the Act, guidance related to application of the Act that may be issued in the future, and actions that the Company may take as a result of the expected impact of the Act. The Company will adjust the amounts recognized related to the Act if more information becomes available. The Company did not make any measurement period adjustments related to the Act in the six months ended July 1, 2018

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessee recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. For the Company, the new standard is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. A modified retrospective approach is required with an option to use certain practical expedients. The Company is currently evaluating the impact on its financial statements. Although the impact is not currently estimable, the Company expects to recognize right-of-use lease assets and lease liabilities for most of the leases it currently accounts for as operating leases. The right-of-use lease assets to be recognized will be adjusted by certain closed-restaurant lease reserves, accrued rent including accruals to expense operating lease payments on a straight-line basis, and unamortized lease incentives upon the adoption of Topic 842. The Company intends to elect the transition practical expedient package as well as the practical expedient to combine lease and non-lease components of the contracts, which may result in reclassification of certain occupancy related expenses to restaurant rent expenses in the consolidated statement of operations. In addition, the Company will be required to record an initial adjustment to retained earnings associated with previously deferred gains on sale-leaseback transactions, and for any future sale-leaseback transactions, the gain, adjusted for any off-market terms, will be recorded immediately. Currently the Company amortizes sale-leaseback gains over the lease term. The Company has not assessed the potential impact of Topic 842 on its covenant financial ratios as the Company's senior credit facility does not give effect to any change in GAAP arising out of Topic 842. The Company is continuing its assessment of the impact of Topic 842 and may identify other impacts.

Reclassification	Reclassification. Write-offs of site development costs were reclassified from general and administrative expense to other expense (income), net in the condensed consolidated statement of operations to conform with the current year presentation.
Revenue Recognition	Revenue Recognition. Revenue is recognized upon transfer of promised products or services to customers in an amount that reflects the consideration the Company received in exchange for those products or services. Revenues from the Company's owned and operated restaurants are recognized when payment is tendered at the time of sale. Franchise royalty revenues are based on a percent of gross sales and are recorded as income when earned. Initial franchise fees and area development fees associated with new franchise agreements are not distinct from the continuing rights and services offered by the Company during the term of the related franchise agreements and are recognized as income over the term of the related franchise agreements. A portion of the initial franchise fee is allocated to training services and is recognized as revenue when the Company completes the training services. Prior to adopting Topic 606, the Company recognized initial franchise fees as revenue in the period that a franchised location opened for business. See Note 6 - Business Segment Information. Gift cards
Fair Value of Financial Instruments	Fair Value of Financial Instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. In determining fair value, the accounting standards establish a three level hierarchy for inputs used in measuring fair value as follows: Level 1 inputs are quoted prices in active markets for identical assets or liabilities; Level 2 inputs are observable for the asset or liability, either directly or indirectly, including quoted prices in active markets for similar assets or liabilities; and Level 3 inputs are unobservable and reflect our own assumptions. The following methods were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate the fair value: • Current Assets and Liabilities. The carrying values reported on the balance sheet of cash, accounts receivable and accounts payable approximate fair value because of the short maturity of those financial instruments. • Revolving Credit Borrowings.
Long-Lived Assets	Long-Lived Assets . The Company assesses the recoverability of property and equipment and definite-lived intangible assets by determining whether the carrying value of these assets can be recovered over their respective remaining lives through undiscounted future operating cash flows. Impairment is reviewed when events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. See Note 3 - Impairment of Long-Lived Assets.
Use of Estimates	Use of Estimates. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements. Estimates also affect the reported amounts of expenses during the reporting periods. Significant items subject to such estimates and assumptions include: accrued occupancy costs, insurance liabilities, evaluation for impairment of goodwill and long-lived assets and lease accounting matters. Actual results could differ from those estimates.
Impairment of Long-Lived Assets	The Company reviews its long-lived assets, principally property and equipment, for impairment at the restaurant level. In addition to considering management’s plans, known regulatory or governmental actions and damage due to acts of God (hurricanes, tornadoes, etc.), the Company considers a triggering event to have occurred related to a specific restaurant if the restaurant’s cash flows for the last twelve months are less than a minimum threshold or if consistent levels of cash flows for the remaining lease period are less than the carrying value of the restaurant’s assets. If an indicator of impairment exists for any of its assets, an estimate of undiscounted future cash flows over the life of the primary asset for each restaurant is compared to that long-lived asset’s carrying value. If the carrying value is greater than the undiscounted cash flow, the Company then determines the fair value of the asset and if an asset is determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value. There is uncertainty in the projected undiscounted future cash flows used in the Company's impairment review analysis. If actual performance does not achieve the projections, the Company may recognize impairment charges in future periods, and such charges could be material. For closed restaurant locations, the Company reviews the future minimum lease payments and related ancillary costs from the date of the restaurant closure to the end of the remaining lease term and records a lease charge for the lease liabilities to be incurred, net of any estimated sublease recoveries. There is uncertainty in the estimates of future lease costs and sublease recoveries. Actual costs and sublease recoveries could vary significantly from the estimated amounts and result in additional lease charges or recoveries, and such amounts could be material.
Purchase of Treasury Stock	Purchase of treasury stock On February 26, 2018, the Company announced that its board of directors approved a share repurchase program for up to 1.5 million shares of the Company's common stock. Under the share repurchase program, shares may be repurchased from time to time in open market transactions at prevailing market prices, in privately negotiated transactions or by other means in accordance with federal securities laws, including Rule 10b-18 under the Securities Exchange Act of 1934, as amended. The share repurchase program has no time limit and may be modified, suspended, superseded or terminated at any time by the Company's board of directors.

Net Income per Share	The Company computes basic net income (loss) per share by dividing net income (loss) applicable to common shares by the weighted average number of common shares outstanding during each period. Our non-vested restricted shares contain a non-forfeitable right to receive dividends on a one-to-one per share ratio to common shares and are thus considered participating securities. The impact of the participating securities is included in the computation of basic net income per share pursuant to the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings attributable to common shares and participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Net income per common share is computed by dividing undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and non-vested restricted shares based on the weighted average shares outstanding during the period.Diluted earnings per share reflects the potential dilution that could occur if our restricted stock units were to be converted into common shares. Restricted stock units with performance conditions are only included in the diluted earnings per share calculation to the extent that performance conditions have been met at the measurement date. We compute diluted earnings per share by adjusting the basic weighted average number of common shares by the dilutive effect of the restricted stock units, determined using the treasury stock method.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessee recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. For the Company, the new standard is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. A modified retrospective approach is required with an option to use certain practical expedients. The Company is currently evaluating the impact on its financial statements. Although the impact is not currently estimable, the Company expects to recognize right-of-use lease assets and lease liabilities for most of the leases it currently accounts for as operating leases. The right-of-use lease assets to be recognized will be adjusted by certain closed-restaurant lease reserves, accrued rent including accruals to expense operating lease payments on a straight-line basis, and unamortized lease incentives upon the adoption of Topic 842. The Company intends to elect the transition practical expedient package as well as the practical expedient to combine lease and non-lease components of the contracts, which may result in reclassification of certain occupancy related expenses to restaurant rent expenses in the consolidated statement of operations. In addition, the Company will be required to record an initial adjustment to retained earnings associated with previously deferred gains on sale-leaseback transactions, and for any future sale-leaseback transactions, the gain, adjusted for any off-market terms, will be recorded immediately. Currently the Company amortizes sale-leaseback gains over the lease term. The Company has not assessed the potential impact of Topic 842 on its covenant financial ratios as the Company's senior credit facility does not give effect to any change in GAAP arising out of Topic 842. The Company is continuing its assessment of the impact of Topic 842 and may identify other impacts.
