Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Other Matters	(1) Organization and Other Matters Business Potbelly Corporation (the “Company” or “Potbelly”), through its wholly owned subsidiaries, owns or operates more than 400 company-owned shops in the United States. Additionally, Potbelly franchisees operate over 40 shops in the United States. Basis of Presentation The unaudited condensed consolidated financial statements and notes herein should be read in conjunction with the audited consolidated financial statements of Potbelly Corporation and its subsidiaries and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 29, 2019. The unaudited condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to the SEC rules and regulations. In the opinion of management, all adjustments, which are of a normal and recurring nature (except as otherwise noted), that are necessary to present fairly the Company’s balance sheet as of March 29, 2020 and December 29, 2019, its statement of operations for the 13 weeks ended March 29, 2020 and March 31, 2019, the statement of equity for the 13 weeks ended March 29, 2020 and March 31, 2019, and its statement of cash flows for the 13 weeks ended March 29, 2020 and March 31, 2019 have been included. The consolidated statements of operations for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year. The Company does not have any components of other comprehensive income recorded within its consolidated financial statements and therefore, does not separately present a statement of comprehensive income in its condensed consolidated financial statements. COVID-19 On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus ("COVID-19") and the risks to the international community as the virus spreads globally. On March 11, 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. In response to the pandemic, many states and jurisdictions in which we operate have issued stay-at-home orders and other measures aimed at slowing the spread of the coronavirus. While most of our company-owned shops remain open in accordance with guidance from local authorities, these measures resulted in us closing the vast majority our dining rooms and shifting to off-premise operations only, and we experienced a sudden and drastic decrease in revenues. The disruption in operations and reduction in revenues have led the Company to consider the impact of the COVID-19 pandemic on the recoverability of its assets, including property and equipment, right-of-use assets for operating leases, goodwill and intangible assets, and others. Due to the impact of the COVID-19 pandemic, the Company performed impairment analyses of its goodwill, intangible assets, and long-lived assets, which includes property and equipment and right-of-use assets for operating leases, as of March 29, 2020. The impairment assessments for both goodwill and indefinite lived intangible assets resulted in the conclusion that the fair value of these assets exceeded their carrying values. Accordingly, the Company did not record any impairment to its goodwill or indefinite-lived intangible assets during the thirteen weeks ended March 29, 2020. The Company recorded an impairment charge for its long-lived assets of $5.9 million for the 13 weeks ended March 29, 2020, primarily driven by the expected impact of the COVID-19 pandemic on future cash flows. The ultimate severity and longevity of the COVID-19 pandemic is unknown, and therefore, it is possible that impairments could be identified in future periods, and such amounts could be material. See Note 3 for further details. The Company recognized an income tax benefit of $3.7 million for the thirteen weeks ended March 29, 2020 primarily due to the impact of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”). The Company estimates that it will be able to obtain a tax refund of $3.7 million from the carryback of NOLs and a refund of prior AMT credits. See Note 5 for further details. To preserve financial flexibility, the Company drew the $40.0 million of available capacity under its revolving credit facility. Due to the pandemic’s impact on revenues, the Company is in discussions with its lender regarding modifications to financial covenants related to the revolving credit facility. See Note 7 for further details. The full impact of the COVID-19 outbreak continues to evolve as of the date of this report. Due to the rapid development and fluidity of this situation, the Company cannot determine the ultimate impact that the COVID-19 pandemic will have on its consolidated financial condition, liquidity, and future results of operations, and therefore any prediction as to the ultimate material adverse impact on the Company’s consolidated financial condition, liquidity, and future results of operations is uncertain. Going Concern Under ASC 205, Presentation of Financial Statements, the Company is required to consider and has evaluated whether there is substantial doubt that it has the ability to meet its obligations within one year from the financial statement issuance date. This assessment also includes the Company’s consideration of any management plans to alleviate such doubts. The conditions described above related to the COVID-19 pandemic have had a material adverse impact on the Company’s revenues, profitability, and cash flows. Because of these conditions, the Company has concluded that it is probable that it will not be in compliance with certain financial covenants of the Credit Agreement Amendment, which are further described in Note 7, for a period of one year from the financial statement issuance date. The probable inability of the Company to meet its current covenant requirements raises substantial doubt on the Company’s ability to meet its obligations within one year from the financial statement issuance date and to continue as a going concern. If the Company is unable to maintain compliance with the covenants contained in the current Credit Agreement, it may be unable to make additional borrowings on any undrawn amounts and may be required to repay its then outstanding borrowings. The Company is in continued negotiations with its current lender and expects further amendments to the Credit Agreement as needed to maintain compliance with future financial covenants, but we cannot make any assurances regarding the likelihood, certainty or exact timing of further amendments to the Credit Agreement. The Company is also evaluating various alternatives to improve its liquidity, including but not limited to, lease concessions and deferrals, further reductions of operating and capital expenditures, and raising additional capital. The condensed consolidated financial statements included in this interim report on Form 10-Q do not include any adjustments that might result from the outcome of this uncertainty. Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Potbelly Corporation; its wholly owned subsidiary, Potbelly Illinois, Inc. (“PII”); PII’s wholly owned subsidiaries, Potbelly Franchising, LLC and Potbelly Sandwich Works, LLC (“LLC”); seven of LLC’s wholly owned subsidiaries and LLC’s seven joint ventures, collectively, the “Company.” All intercompany balances and transactions have been eliminated in consolidation. For consolidated joint ventures, non-controlling interest represents a non-controlling partner’s share of the assets, liabilities and operations related to the seven joint venture investments. The Company has ownership interests ranging from 51-80% in these consolidated joint ventures. Fiscal Year The Company uses a 52/53-week fiscal year that ends on the last Sunday of the calendar period. Approximately every five or six years a 53rd week is added. Fiscal year 2020 and 2019 both consist of 52 weeks. The fiscal quarters ended March 29, 2020 and March 31, 2019 each consisted of 13 weeks. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Significant estimates include amounts for long-lived assets and income taxes. Actual results could differ from those estimates. Recent Accounting Pronouncements On December 30, 2019, the Company adopted Accounting Standard Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326). This pronouncement requires the measurement and recognition of expected credit losses on financial instruments. ASU 2016-13 replaces the existing incurred loss model with a forward-looking expected credit loss model that requires consideration of a broader range of information to estimate credit losses. The Company recorded a net reduction of $5 thousand to opening accumulated deficit as of December 30, 2019, due to the cumulative impact of adopting Topic 326.
