Basis of Presentation and Summary of Significant Accounting Policies | BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview El Pollo Loco Holdings, Inc. (“Holdings”) is a Delaware corporation headquartered in Costa Mesa, California. Holdings and its direct and indirect subsidiaries are collectively known as “we,” “us” or the “Company.” The Company’s activities are conducted principally through its indirect wholly-owned subsidiary, El Pollo Loco, Inc. (“EPL”), which develops, franchises, licenses, and operates quick-service restaurants under the name El Pollo Loco® and operates under one operating segment. At March 27, 2019 , the Company operated 211 and franchised 273 El Pollo Loco restaurants. On August 2, 2018, the Company announced the Board of Directors had authorized a stock repurchase program (the “Stock Repurchase Program”). The Company entered into a stock repurchase plan pursuant to Rule 10b5-1 of the Securities and Exchange Act of 1934, as amended on August 28, 2018 (the “Stock Repurchase Plan”), which allows for the repurchase of up to $20.0 million of the Company’s common stock. The Stock Repurchase Plan commenced purchases on November 6, 2018, and, if not terminated sooner by other provisions of the Stock Repurchase Plan, will terminate on June 26, 2019. The Stock Repurchase Plan may also be suspended or terminated at any time upon prior notice. Under the Stock Repurchase Program, the Company may repurchase its common stock from time to time, in amounts and at prices that the Company deems appropriate, subject to market conditions and other considerations. The Company’s repurchases may be executed using open market purchases and/or through privately negotiated transactions. For the quarter ended March 27, 2019 , the Company repurchased 255,554 shares of common stock under the Stock Repurchase Plan, using open market purchases, for total consideration of approximately $3.4 million . Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments necessary for a fair presentation of the Company’s consolidated financial position and results of operations and cash flows for the periods presented. Interim results of operations are not necessarily indicative of the results that may be achieved for the full year. The condensed consolidated financial statements and related notes do not include all information and footnotes required by GAAP for annual reports. This quarterly report should be read in conjunction with the condensed consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 26, 2018 . The Company uses a 52- or 53-week fiscal year ending on the last Wednesday of the calendar year. In a 52-week fiscal year, each quarter includes 13 weeks of operations; in a 53-week fiscal year, the first, second and third quarters each include 13 weeks of operations, and the fourth quarter includes 14 weeks of operations. Every six or seven years, a 53-week fiscal year occurs. Fiscal 2018 and 2019 are both 52-week years, ending on December 26, 2018 and December 25, 2019 , respectively. Revenues, expenses, and other financial and operational figures may be elevated in a 53-week year. Holdings has no material assets or operations. Holdings and Holdings’ direct subsidiary, EPL Intermediate, Inc. (“Intermediate”), guarantee EPL’s 2018 Revolver (as defined below) on a full and unconditional basis (see Note 4), and Intermediate has no subsidiaries other than EPL. EPL is a separate and distinct legal entity and has no obligation to make funds available to Intermediate. EPL and Intermediate may pay dividends to Intermediate and to Holdings, respectively. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Holdings and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of 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 disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and revenue and expenses during the periods reported. Actual results could materially differ from those estimates. The Company’s significant estimates include estimates for impairment of goodwill, intangible assets and property and equipment, insurance reserves, lease termination liabilities, closed-store reserves, stock-based compensation, income tax receivable agreement liability, contingent liabilities and income tax valuation allowances. Cash and Cash Equivalents The Company considers all highly-liquid instruments with an original maturity of three months or less at the date of purchase to be cash equivalents. Liquidity The Company’s principal liquidity requirements are to service its debt and to meet capital expenditure needs. At March 27, 2019 , the Company’s total debt was $71.2 million . The Company’s ability to make payments on its indebtedness and to fund planned capital expenditures depends on available cash and its ability to generate adequate cash flows in the future, which, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond the Company’s control. Based on current operations, the Company believes that its cash flow from operations, available cash of $6.7 million at March 27, 2019 , and available borrowings under the 2018 Revolver (see Note 4) will be adequate to meet the Company’s liquidity needs for the next twelve months from the filing of these condensed consolidated financial statements. Recovery of Securities Class Action Legal Expense During the thirteen weeks ended March 28, 2018 , the Company received insurance proceeds of $1.6 million related to the reimbursement of certain legal expenses paid in prior years for the defense of securities lawsuits. See Note 7, Commitments and Contingencies, Legal Matters. Assets Held For Sale During the thirteen weeks ended March 27, 2019 , the Company agreed in principle to sell four restaurants within the San Francisco area to an existing franchisee. Additionally, the Company agreed in principle to sell seven restaurants in the Phoenix area to another existing franchisee. Assets are classified as held for sale if they meet the criteria outlined in ASC 360, Property, Plant and Equipment . In accordance with applicable accounting guidance, the net assets were recorded at the lower of carrying value or fair value less costs to sell. The Company classified $4.5 million of assets as held for sale, consisting of leasehold improvements and other property equipment, as of March 27, 2019 , and recognized a loss on held for sale assets of $4.1 million for the thirteen weeks ended March 27, 2019 . Recently Adopted Accounting Pronouncements In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, “Disclosure Update and Simplification ” , amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. The Company adopted SEC Release No. 33-10532 as of March 27, 2019. See “Consolidated Statements of Changes in Stockholders’ Equity” above. In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-07, “Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting”, (“ASU 2018-07”) which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. ASU 2018-07 is effective for financial statements issued for annual periods beginning after December 15, 2018, and for the interim periods therein. The Company adopted ASU 2018-07 as of March 27, 2019 and it did not have a significant impact on the Company’s consolidated financial position or results of operations. In February 2016, the FASB issued ASU No. 2016-02, “Leases”, (“Topic 842”). Topic 842 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU Asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods therein. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11 which provides an alternative transition method that allows entities to apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted Topic 842, and all related ASU’s in the first quarter of 2019. See “Changes in Accounting Policies,” below for further details. Subsequent Events Subsequent to March 27, 2019 , the Company completed the sale of four restaurants in the San Francisco area to an existing franchisee. See "Assets Held For Sale" above for further details related to the accounting impact as of and for the thirteen weeks ended March 27, 2019 . Furthermore, the Company made a $4.0 million borrowing on the 2018 Revolver. Additionally, the Company’s Board of Directors, on April 30, 2019, as part of the Company’s focus on shareholder returns, approved a new share repurchase program under which it authorized the Company, at its discretion, to repurchase up to $30.0 million of its outstanding common stock. The new share repurchase program will commence on June 27, 2019, subsequent to the expiration of the current share repurchase program. The share repurchase program will terminate on March 25, 2020 , if not terminated sooner by other provisions of the share repurchase program, and may also be suspended or terminated at anytime upon prior notice. Repurchases of the Company’s outstanding common stock will be made in accordance with applicable securities laws and may be made at management’s discretion from time to time in the open market, through privately negotiated transactions or otherwise, including pursuant to Rule 10b5-1 trading plans. There is no guarantee as to the exact number of shares to be repurchased by the Company. The timing and extent of repurchases will depend upon several factors, including market and business conditions, regulatory requirements and other corporate considerations, and repurchases may be discontinued at any time. The Company evaluated subsequent events that have occurred after March 27, 2019 , and determined that there were no other events or transactions occurring during this reporting period that require recognition or disclosure in the condensed consolidated financial statements. Concentration of Risk Cash and cash equivalents are maintained at financial institutions and, at times these balances may exceed federally-insured limits. The Company has never experienced any losses related to these balances. The Company had no supplier for which amounts due totaled more than 10.0% of the Company’s accounts payable at March 27, 2019 . As of December 26, 2018 , the Company had one supplier for which amounts due totaled 36.0% of the Company’s accounts payable. Purchases from the Company’s largest supplier totaled 26.6% of total expenses for the thirteen weeks ended March 27, 2019 and 28.0% of total expenses for the thirteen weeks ended March 28, 2018 . Company-operated and franchised restaurants in the greater Los Angeles area generated, in the aggregate, approximately 69.2% of total revenue for both the thirteen weeks ended March 27, 2019 and the thirteen weeks ended March 28, 2018 . Revenue Recognition In the first quarter of 2018 the Company implemented Topic 606. Revenue is measured based on a consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Topic 606 defines a five-step process to achieve this core principle. Refer to Note 10, “Revenue From Contracts With Customers” for further details on the Company’s revenue recognition policy. Goodwill and Indefinite Lived Intangible Assets The Company’s indefinite-lived intangible assets consist of trademarks. Goodwill represents the excess of cost over fair value of net identified assets acquired in business combinations accounted for under the purchase method. The Company does not amortize its goodwill and indefinite-lived intangible assets. Goodwill resulted from the acquisition of certain franchise locations. Upon the sale or closure of a restaurant, the Company evaluates whether there is a decrement of goodwill. The amount of goodwill included in the cost basis of the asset sold is determined based on the relative fair value of the portion of the reporting unit disposed of compared to the fair value of the reporting unit retained. The Company performs annual impairment tests for goodwill during the fourth fiscal quarter of each year, or more frequently if impairment indicators arise. The Company reviews goodwill for impairment utilizing either a qualitative assessment or a fair value test by comparing the fair value of a reporting unit with its carrying amount. If the Company decides that it is appropriate to perform a qualitative assessment and concludes that the fair value of a reporting unit more likely than not exceeds its carrying value, no further evaluation is necessary. If the Company performs the fair value test, the Company will compare the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its fair value, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit. The Company performs annual impairment tests for indefinite-lived intangible assets during the fourth fiscal quarter of each year, or more frequently if impairment indicators arise. An impairment test consists of either a qualitative assessment or a comparison of the fair value of an intangible asset with its carrying amount. The excess of the carrying amount of an intangible asset over its fair value is recognized as an impairment loss. The assumptions used in the estimate of fair value are generally consistent with the past performance of the Company’s reporting segment and are also consistent with the projections and assumptions that are used in current operating plans. These assumptions are subject to change as a result of changing economic and competitive conditions. The Company did not identify any indicators of potential impairment of its goodwill or indefinite-lived intangible assets during the thirteen weeks ended March 27, 2019 or March 28, 2018 , and therefore did not record any impairment during the respective periods. Fair Value Measurements Fair value is 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. Financial assets and liabilities carried at fair value are classified and disclosed in one of the following three categories: • 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 whose inputs or significant value drivers are observable. • Level 3: Unobservable inputs used when little or no market data is available. As of March 27, 2019 and December 26, 2018 , the Company had no assets or liabilities measured at fair value on a recurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. In other words, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). The following non-financial instruments were measured at fair value, on a nonrecurring basis, as of and for the thirteen weeks ended March 27, 2019 . This reflects certain property and equipment assets, which were classified as held for sale as of March 27, 2019 . The fair value of the assets was determined using Level 3 unobservable inputs not corroborated by market data, consisting of third-party offers for the building and equipment (in thousands): Fair Value Measurements at March 27, 2019 Using Thirteen Weeks Ended March 27, 2019 Total Level 1 Level 2 Level 3 Loss on assets held for sale Property and equipment owned, net $ 4,494 $ — $ — $ 4,494 $ 4,124 The Company had no assets or liabilities measured at fair value on a nonrecurring basis for the thirteen weeks ended March 28, 2018 . Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment on a restaurant-by-restaurant basis whenever events or changes in circumstances indicate that the carrying value of certain assets may not be recoverable. 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 undiscounted cash flows for the remaining lease period are less than the carrying value of the restaurant’s assets. If the Company concludes that the carrying value of certain assets will not be recovered based on expected undiscounted future cash flows, an impairment loss is recorded to reduce the assets to their estimated fair value. The fair value is measured on a nonrecurring basis using unobservable (Level 3) inputs. There is uncertainty in the projected undiscounted future cash flows used in the Company’s impairment review analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods, and such charges could be material. Based on the results of the analysis, the Company did not recognize any impairment charges during the thirteen weeks ended March 27, 2019 and March 28, 2018 . Given the difficulty in projecting results for newer restaurants in newer markets, we are monitoring the recoverability of the carrying value of the assets of several restaurants on an ongoing basis. For these restaurants, if expected performance improvements are not realized, an impairment charge may be recognized in future periods, and such charge could be material. Closed-Store Reserves Prior to the adoption of Topic 842 “Leases” when the Company closed a restaurant, it reviewed 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 recorded a lease charge for the lease liabilities to be incurred, net of any estimated sublease recoveries. The estimates of future closed-store reserves were re-evaluated and adjusted each period based on information available as of the period. In addition, an impairment charge was recognized for any remaining carrying value of certain restaurant assets. During the thirteen weeks ended March 28, 2018 , the Company closed two restaurants in Texas, both of which were previously impaired during the third quarter of 2017, and decided not to move forward with the development of a third location in Texas resulting in a closed store reserve expense of $2.8 million . Subsequent to the adoption of Topic 842, the Company no longer recognizes a closed-store reserve when the Company closes a restaurant, as a lease liability related to the future lease payments is already recognized. Rather, when a restaurant is closed, the Company will evaluate the ROU Asset for impairment, based on anticipated sublease recoveries. The remaining value of the ROU Asset is amortized on a straight-line basis, with the expense recognized in closed-store reserve expense. During the thirteen weeks ended March 27, 2019 , the Company closed one restaurant in California and one in Texas and recognized $0.3 million of closed-store reserve expense, primarily related to the amortization of ROU Assets for closed stores. Income Taxes The provision for income taxes, income taxes payable and deferred income taxes is determined using the asset and liability method. Deferred tax assets and liabilities are determined based on temporary differences between the financial carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect in the years in which the temporary differences are expected to reverse. On a periodic basis, the Company assesses the probability that its net deferred tax assets, if any, will be recovered. If, after evaluating all of the positive and negative evidence, a conclusion is made that it is more likely than not that some portion or all of the net deferred tax assets will not be recovered, a valuation allowance is provided by charging to tax expense to reserve the portion of deferred tax assets which are not expected to be realized. The Company reviews its filing positions for all open tax years in all U.S. federal and state jurisdictions where the Company is required to file. When there are uncertainties related to potential income tax benefits, in order to qualify for recognition, the position the Company takes has to have at least a “more likely than not” chance of being sustained (based on the position’s technical merits) upon challenge by the respective authorities. The term “more likely than not” means a likelihood of more than 50 percent. Otherwise, the Company may not recognize any of the potential tax benefit associated with the position. The Company recognizes a benefit for a tax position that meets the “more likely than not” criterion at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon its effective resolution. Unrecognized tax benefits involve management’s judgment regarding the likelihood of the benefit being sustained. The final resolution of uncertain tax positions could result in adjustments to recorded amounts and may affect the Company’s consolidated financial position, results of operations, and cash flows. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties at March 27, 2019 or at December 26, 2018 , and did not recognize interest or penalties during the thirteen weeks ended March 27, 2019 or March 28, 2018 , since there were no material unrecognized tax benefits. Management believes no material changes to the amount of unrecognized tax benefits will occur within the next twelve months. In fiscal 2017, President Trump signed into law “the Tax Cuts and Jobs Act”. The Tax Cuts and Jobs Act provides for significant changes in the U.S. Internal Revenue Code of 1986, as amended (the “Code”). The Tax Cuts and Jobs Act contains provisions with separate effective dates but is generally effective for tax years beginning after December 31, 2017. Among other changes, the Tax Cuts and Jobs Act lowers the federal corporate income tax rate from 35% to 21% , repeals the corporate alternative minimum tax (“AMT”), limits the deductibility of interest expense and performance based incentive compensation, allows for 100% bonus depreciation on qualified fixed asset additions placed in service on or after September 27, 2017 and implements a modified territorial tax system. For tax years beginning in 2018, 2019 and 2020, to the extent AMT credit carryovers exceed regular tax liability, 50% of the excess of AMT credit carryovers would be refundable. Any remaining AMT credits would be fully refundable in 2021. The Tax Cuts and Jobs Act impacted the Company’s consolidated results of operations in the current period, and is expected to continue to impact its consolidated results of operations in future periods. Impacts from the Tax Cuts and Jobs Act include the reduction in the federal corporate income tax rate from 35% to 21% and additional meals subject to the 50% disallowance that were previously 100% deductible. The Company may also be subject to future disallowance of deductions for certain executive compensation as a result of the changes to the Code section 162(m). We may make further refinements to our deferred tax assets related to executive compensation based upon technical guidance that may be published and changes to current interpretations of certain provisions of the Tax Cuts and Jobs Act. Any impact to our provision for income taxes as the result of additional guidance will be recorded in the period in which the guidance is issued. On July 30, 2014, the Company entered into the TRA, which calls for the Company to pay to its pre-IPO stockholders 85% of the savings in cash that the Company realizes in its income taxes as a result of utilizing its net operating losses and other tax attributes attributable to preceding periods. For the thirteen weeks ended March 27, 2019 , we recorded income tax receivable agreement expense of $0.2 million and for the thirteen weeks ended March 28, 2018 , we recorded income tax receivable agreement income of $0.9 million related to the amortization of interest expense related to our total expected TRA payments and changes in estimates for actual tax returns filed and future forecasted taxable income. Changes in Accounting Policies Except for the changes below, the Company has consistently applied the accounting policies to all periods presented in these condensed consolidated financial statements. The Company adopted Topic 842, with a date of initial application of December 27, 2018. As a result, the Company has changed its accounting policy for leases as detailed below. The Company’s operations utilize property, facilities, equipment and vehicles owned by the Company or leased from others, the majority of which are operating leases. Additionally, the Company has various contracts with vendors that have been determined to contain an embedded lease in accordance with Topic 842. As of the date of adoption, the Company recognized a ROU Asset and lease liability equal to the present value of these leases within its consolidated balance sheet for any leases with terms longer than 12 months. The Company also has three finance leases, subleases facilities to certain franchises and is the lessor for certain property, facilities and equipment owned by the Company. The adoption of this ASU did not have an impact on our current accounting policies for these items. Furthermore, the adoption of this standard did not have any impact on the Company’s consolidated statement of operations or the consolidated statement of cash flows. The Company applied Topic 842 using the effective date method, which allowed the Company to apply the standard as of the adoption date, and to recognize the cumulative effect of initially applying Topic 842 as an adjustment to retained earnings at December 27, 2018, if applicable. Therefore, the comparative information has not been adjusted and continues to be reported under Topic 840. However, the Company did not have any impact to its retained earnings. Additionally, the Company elected to apply the package of practical expedients, which allows for carryforwards of 1) historical lease classifications, 2) determination of whether a contract contains a lease under the new definition of a lease and 3) whether previously capitalized initial direct costs qualify for capitalization. |
