Additionally, in February 2011, the Company opened its first international franchise in the Middle East. In July 2015, the Company opened its first franchise shop398 company-owned shops in the United ~~Kingdom and~~States. Additionally, Potbelly franchisees operate 45 shops in ~~October 2016,~~ the ~~Company opened its first franchise shop in Canada.~~ Additionally, during April 2016, the Company transitioned a franchise shop to a company-operated shop for a purchase price of $1.1 million.

The unaudited condensed consolidated financial statements included herein have been prepared by ~~the Company~~us 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 financial position~~our balance sheet as of ~~September 24, 2017~~June 27, 2021 and December ~~25, 2016, its~~27, 2020, our statement of operations for the 13 and 3926 weeks ended ~~September 24, 2017~~June 27, 2021 and ~~September 25, 2016~~June 28, 2020, the statement of equity for the 13 and ~~its~~26 weeks ended June 27, 2021 and June 28, 2020, and our statement of cash flows for the 3926 weeks ended ~~September 24, 2017~~June 27, 2021 and ~~September 25, 2016~~June 28, 2020 have been included. The condensed 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~~Beginning with the third quarter of 2020, shop closure and lease termination expenses are being presented within impairment, loss on disposal of property and equipment and shop closures in our condensed consolidated statements of operations. Prior to the third quarter of 2020, shop closure and lease termination expenses were presented within general and administrative expenses. Prior period amounts have been reclassified to conform to the current presentation. This reclassification and certain other reclassifications had no impact on the loss from operations, balance sheets or statements of cash flows.

We do not have any components of other comprehensive income recorded within ~~its~~our consolidated financial statements and therefore, does not separately present a statement of comprehensive income in ~~its~~our condensed consolidated financial statements.

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 issued stay-at-home orders and other measures aimed at slowing the spread of the coronavirus, resulting in significant changes to our operations and a sudden and drastic decrease in revenues. While the pandemic continues to have an impact on our business, the distribution of COVID-19 vaccines and a decline in positive cases and hospitalizations has resulted in a gradual improvement in our sales during the first half of 2021. Nearly all of our shops have reopened their dining rooms and are no longer subject to the operating restrictions and capacity limits related to COVID-19. We continue to follow guidance from local authorities in determining the appropriate restrictions to put in place for each shop, including the suspension or reduction of in-shop dining if required due to changes in the pandemic response in each jurisdiction.

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, we cannot determine the ultimate impact that the COVID-19 pandemic will have on our consolidated financial condition, liquidity, and future results of operations, and therefore any prediction as to the ultimate impact on our consolidated financial condition, liquidity, and future results of operations is uncertain.

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”~~PSW”); ~~eight~~7 of ~~LLC’s~~PSW’s wholly owned subsidiaries and ~~LLC’s five~~PSW’s 7 joint ventures, collectively, the “Company.” All ~~significant~~ 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 ~~five~~seven joint venture investments. ~~The Company~~Potbelly has ownership interests ranging from 51-80% in these consolidated joint ventures.

~~The Company uses~~We use 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 ~~2017 consists of 53 weeks~~2021 and ~~2016 consisted~~2020 both consist of 52 weeks. The fiscal quarters ended ~~September 24, 2017~~June 27, 2021 and ~~September 25, 2016~~June 28, 2020 each consisted of 13 weeks.

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.

On December 28, 2020, we adopted Accounting Standard Update No. 2020-06, Debt—Debt with Conversion and ~~Revised Financial Accounting Standards~~

~~In May 2014,~~Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40). This pronouncement simplifies the ~~Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts~~accounting for certain financial instruments with ~~Customers.” The pronouncement was issued~~liability and equity characteristics, including convertible instruments and contracts on an entity’s own equity. It removes certain criteria that previously had to ~~clarify~~be satisfied in order to classify a contract as equity and revises the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and International Financial Reporting Standards (IFRS). The FASB approved a one-year deferralguidance on calculating earnings per share, requiring use of the ~~effective date~~if-converted method for all convertible instruments and rescinding a company’s ability to rebut the presumption of ~~ASU 2014-09, such~~share settlement for instruments that ~~it will become effective~~may be settled in cash or other. There was no impact to our financial statements or loss per share presentation in the period of adoption due to the impact of adopting this pronouncement.

We primarily earn revenue at a point in time for the annual period beginning after December 15, 2017. In addition, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12 in March 2016, April 2016 and May 2016, respectively, to help provide interpretive clarifications on the new guidance in Accounting Standards Codification (ASC) Topic 606. Potbelly will adopt the standard effective the first quarter of 2018 and apply the amendments using the modified retrospective method. The Company has determined that the adoption will not have a material impact on sandwich shop sales, ~~but will impact franchise~~which can occur in person at the shop, over our online or app platforms, or through a third-party platform. Sales taxes collected from customers are excluded from revenues and the obligation is included in accrued liabilities until the taxes are remitted to the appropriate taxing authorities. We have other revenue ~~and gift card breakage. Potbelly licenses intellectual property and trademarks to franchisees through franchise arrangements. As part of these agreements, Potbelly receives~~generating activities outlined below.

We earn an initial franchise fee, ~~payment which is~~ a franchise development agreement fee and ongoing royalty fees under our franchise agreements. Initial franchise fees are considered highly dependent upon and interrelated with the franchise right granted in the franchise agreement. As such, these franchise fees are recognized ~~as revenue~~ ~~when~~over the ~~shop opens. Effective~~contractual term of the franchise agreement. We record a contract liability for the ~~annual period beginning January 1, 2018,~~ unearned portion of the initial franchise fees. Franchise development agreement fees represent the exclusivity rights for a geographical area paid by a third party to develop Potbelly shops for a certain period of time. Franchise development agreement fee~~s will generally be recognized~~ payments received by us are recorded as deferred revenue in the consolidated balance sheet and amortized over the life of the ~~contract. Potbelly sells~~franchise development agreement. Royalty fees are based on a percentage of sales and are recorded as revenue as the fees are earned and become receivable from the franchisee.

We sell gift cards to customers, ~~and records~~record the sale as a ~~liability. The~~contract liability ~~is released once~~and recognize the associated revenue as the gift card is redeemed. ~~Historically a~~A portion of these gift ~~card sales~~cards are not redeemed by the customer, ~~(“breakage”).~~which is recognized by us as revenue as a percentage of customers gift card redemptions. The expected breakage amount recognized is determined by a historical data analysis on gift card redemption patterns.

We recognized gift card breakage income of $0.1 million and $0.1 million for the 26 weeks ended June 27, 2021, and June 28, 2020, respectively, which is recorded within net sandwich shop sales in our condensed consolidated statements of operations.

During the second quarter of 2020, we implemented a new customer loyalty program for customers using the Potbelly ~~recognizes breakage two years after~~Perks application at the ~~period~~point of sale. ~~Effective~~The customer will typically earn 10 points for every dollar spent in addition to any active promotions, and the ~~annual period beginning January 1, 2018, expected breakage~~customer will earn a free entrée after earning 1,000 points. We defer revenue associated with the estimated selling price of points earned by Potbelly Perks members towards free entrées as each point is anticipated to be recognized as customers redeem the gift cards. The Company is continuing its assessment, which may identify additional impacts this standard will have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, “Leases,” which will replace the existing guidance in ASC 840, “Leases.” The pronouncement requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use assetearned, and a corresponding ~~lease liability. For finance leases,~~liability is established in deferred revenue. The deferral is based on the ~~lessee would recognize interest expense and amortization~~estimated value of the ~~right-of-use asset and~~product for ~~operating leases,~~which the ~~lessee would recognize~~reward is expected to be redeemed, net of estimated unredeemed points. Once a ~~straight-line total lease expense. The pronouncement is effective for fiscal years beginning~~customer earns a free entrée, that entrée reward will expire after December 15, 2018, including annual and interim periods thereafter. In addition, the pronouncement requires the use of the modified retrospective method, which will require adjustment to all comparative periods presented in the consolidated financial statements. The Company is currently evaluating the impact ASU 2016-02 will have on its financial position, results of operations and cash flows but expects that it will result30 days. Any point in a ~~material increase in its long-term assets and liabilities given~~customer’s account that does not go toward earning a full entrée will expire a year after the ~~Company has a significant number of leases.~~

~~In March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718).” The pronouncement simplifies the accounting~~point is earned. When points are redeemed, we recognize revenue for the ~~taxes~~redeemed product and reduces deferred revenue.

For the 26 weeks ended June 27, 2021 revenue recognized from all revenue sources on point in time sales was $175.3 million, and revenue recognized from sales over time was $0.3 million. For the 26 weeks ended June 28, 2020, revenue recognized from all revenue sources on point in time sales was $143.5 million, and revenue recognized from sales over time was $0.3 million.

As described above, we record current and noncurrent contract liabilities for upfront franchise fees, gift cards and the loyalty program. There are no other contract liabilities or contract assets recorded by us.

The opening and closing balances of our current and noncurrent contract liabilities from contracts with customers were as follows:

The aggregate value of remaining performance obligations on outstanding contracts was $5.0 million as of June 27, 2021. We expect to recognize revenue related to ~~stock-based compensation, including the accounting for income taxes, forfeitures and statutory tax withholding requirements,~~contract liabilities as follows (in thousands), which may vary based upon franchise activity as well as ~~classification within~~gift card redemption patterns:

For the ~~statement~~13 and 26 weeks ended June 27, 2021, the amount of ~~cash flows. The pronouncement is effective for annual periods beginning after~~revenue recognized related to the December ~~15, 2016, including annual~~27, 2020 liability ending balance was $0.3 million and interim periods thereafter. Potbelly adopted ASU 2016-09 in the first quarter of 2017. The primary impact of adoption was the recognition of excess tax benefits and deficiencies that arise upon vesting or exercise of share-based payments in the Income Statement as income tax expense instead of a component of equity recorded to paid-in capital. ~~This aspect of the new guidance, which was required to be adopted prospectively, resulted in~~ ~~an additional income tax expense of $45 thousand and $292 thousand for~~$0.9 million, respectively. For the 13 weeks and 3926 weeks ended ~~September 24, 2017, respectively. Potbelly has elected to continue to estimate forfeitures expected to occur to determine~~June 28, 2020, the amount of ~~compensation cost~~revenue recognized related to ~~be recognized~~the December 31, 2019 liability ending balance was $0.4 million and $0.9 million, respectively. This revenue related to the recognition of gift card redemptions and upfront franchise fees. For the 13 and 26 weeks ended June 27, 2021 and June 28, 2020, we did 0t recognize any revenue from obligations satisfied (or partially satisfied) in each period. Excess income tax benefits and deficiencies from stock-based compensation arrangements are now classified as cash flow from operations, instead of as cash flow used in financing activities. The Company elected to apply this change in presentation prospectively and as such prior periods have not been adjusted. Additionally, in accordance with the new standard, the Company now excludes excess tax benefits and deficiencies from the assumed proceeds available to repurchase shares in the computation of the Company’s diluted earnings per share.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350).” The new standard eliminates step 2 from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess. Under current U.S. GAAP, to perform step 2 an entity must determine its implied fair value, which is determined in the same manner as the amount of goodwill recognized in a business combination. In addition to eliminating step 2, the new standard eliminates the requirement for a reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step 2 of the goodwill impairment test. Instead, all reporting units, even those with a zero or negative amount will apply the same impairment test. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The standard will be effective for Potbelly in the fiscal year beginning after December 15, 2019. Early adoption for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017 is permitted. This amendment is required to be applied on a prospective basis. Potbelly is currently assessing the impact and timing of adopting this guidance on its consolidated financial statements.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and all other current liabilities approximate fair values due to the short maturities of these balances.

The ~~Company assesses~~book value of the long-term debt under the Credit Agreement, subsequently amended most recently as of February 26, 2021 and further discussed in Note 7, is considered to approximate its fair value as of June 27, 2021 as the interest rates are considered in line with current market rates.

Assets recognized or disclosed at fair value on the consolidated financial statements on a nonrecurring basis include items such as leasehold improvements, property and equipment, operating lease assets, goodwill, and other intangible assets. These assets are measured at fair value if determined to be impaired.

We assess potential impairments to ~~its~~our long-lived assets, which includes property and equipment and lease right-of-use assets, on a quarterly basis or whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. Shop-level assets and right-of-use assets are grouped at the individual shop-level for the purpose of the impairment assessment. Recoverability of an asset group is measured by a comparison of the carrying amount of an asset group to its estimated undiscounted future cash flows expected to be generated by the ~~asset.~~asset group. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset group exceeds the fair value of the ~~asset.~~asset group. The fair value of the shop assets ~~was~~is determined using the discounted future cash flow method of anticipated cash flows through the shop’s lease-end date using fair value measurement inputs classified as Level 3. The fair value of right-of-use assets is estimated using market comparative information for similar properties. Level 3 inputs are derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. After performing a periodic review of ~~the Company’s~~our shops during the 13 weeks and 3926 weeks ended ~~September 24, 2017,~~June 27, 2021, it was determined that indicators of impairment were present for certain shops as a result of continued ~~underperformance. The Company~~underperformance, primarily related to the impacts of COVID-19. We performed an impairment analysis related to these shops and recorded an impairment charge of ~~$1.5 million~~$281 thousand and ~~$5.8 million~~$429 thousand for the 13 and 3926 weeks ended ~~September 24, 2017, respectively.~~ ~~Included within~~June 27, 2021. The ultimate severity and longevity of the ~~impairment charge~~COVID-19 pandemic is unknown, and therefore, it is possible that impairments could be identified in future periods, and such amounts could be material.

During the first quarter of 2021, we amended the lease for ~~the 13 and 39 weeks ended September 24, 2017, impairment charges of $0.7 million were recorded~~our corporate Support Center office in ~~relation~~Chicago to ~~Hurricane Harvey, with insurance recoveries of $0.7 million also recorded~~relocate to a different office space within the same ~~caption.~~ ~~The company recorded an impairment charge~~building. As a result of ~~$1.9~~this relocation, the leasehold improvements of the original office space were disposed, resulting in a loss on disposal of $2.5 million ~~and $2.9 million for~~based on the ~~13 and 39 weeks ended September 25, 2016, respectively.~~remaining net book value of those assets.

Basic and diluted income per common share attributable to common stockholders ~~was~~are calculated using the weighted average number of common shares outstanding for the period. Diluted income per common share attributable to common stockholders is computed by dividing the income allocated to common stockholders by the weighted average number of fully diluted common shares outstanding. In periods of a net loss, no0 potential common shares are included in diluted shares outstanding as the effect is anti-dilutive. For the 13 and 26 weeks ended ~~September 24, 2017, the Company~~June 27, 2021 and June 28, 2020, we had a loss per share, and therefore potentially dilutive shares were excluded ~~for potential stock option exercises and warrant exercises.~~

The following table summarizes the ~~earnings (loss)~~loss per share calculation:

The ~~Company recognized income~~interim tax ~~benefit of $0.5 million on a pre-tax loss of $0.6 million, or~~provision is determined using an estimated annual effective tax rate ~~benefit~~and is adjusted for discrete taxable events that occur during the quarter. We regularly assess the need for a valuation allowance related to our deferred tax assets, which includes consideration of ~~80.4%, for~~both positive and negative evidence related to the ~~13 weeks ended September 24, 2017, compared~~likelihood of realization of such deferred tax assets to determine, based on the weight of the available evidence, whether it is more-likely-than-not that some or all of our deferred tax assets will not be realized. In our assessment, we consider recent financial operating results, projected future taxable income, the reversal of existing taxable differences, and tax planning strategies. We recorded a full valuation allowance against our net deferred tax assets during the first quarter of 2019, resulting in a non-cash charge to income tax expense of ~~$1.0~~$13.6 million. We continue to maintain a valuation allowance against all of our deferred tax assets as of June 27, 2021. We did not provide for an income tax benefit on our pre-tax loss for the 13 and 26 weeks ended June 27, 2021 and June 28, 2020. We assess the likelihood of the realization of our deferred tax assets each quarter and the valuation allowance is adjusted accordingly.

On March 27, 2020, the CARES Act was enacted into law. The CARES Act is a tax and spending package intended to provide economic relief to address the impact of the COVID-19 pandemic. The CARES Act includes several significant business tax provisions that, among other things, would eliminate the taxable income limit for certain NOLs and allow businesses to carry back NOLs arising in 2018, 2019, and 2020 to the five prior tax years, accelerate refunds of previously generated corporate AMT credits, loosen the business interest limitation under section 163(j), and fix the qualified improvement property regulations in the 2017 Tax Cuts and Jobs Act. As a result of the CARES Act, we estimated that we would be able to obtain a tax refund of $6.7 million from the carryback of NOLs and a refund of prior AMT credits. We received the entire amount of the refund during fiscal year 2020. We recognized $3.7 million of this income tax benefit during the first quarter of 2020.

We determine if a contract contains a lease at inception. We lease retail shops, warehouse and office space under operating leases. For leases with renewal periods at our option, we determine the expected lease period based on ~~pre-tax income~~whether the renewal of ~~$2.8~~any options are reasonably assured at the inception of the lease.

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we estimate incremental secured borrowing rates corresponding to the maturities of the leases. We estimate this rate based on prevailing financial market conditions, comparable company and credit analysis, and management judgment.

We recognize expense for these leases on a straight-line basis over the lease term. Additionally, tenant incentives used to fund leasehold improvements are recognized when earned and reduce our right-of-use asset related to the lease. These are amortized through the right-of-use asset as reductions of expense over the lease term.

In fiscal year 2020, as a result of COVID-19, we held discussions with landlords regarding restructuring of our leases in light of various contractual and legal defenses, and we subsequently entered into a total of 342 amendments with our respective landlords through June 27, 2021. The vast majority of these lease amendments were completed during fiscal year 2020, and we are substantially complete with COVID-19-related lease amendments as of June 27, 2021.

During the 13 and 26 weeks ended June 27, 2021, we terminated 1 lease and 3 leases, respectively. We incurred $0 million ~~or an effective tax rate~~and $0.2 million in lease termination fees related to these leases for the 13 and 26 weeks ended June 27, 2021. Upon termination of ~~34.2%, for~~leases during the 13 weeks ended ~~September 25, 2016. The Company recognized income tax expense of $0.3 million on pre-tax income~~June 27, 2021, we derecognized ROU assets of $0.8 million and lease liabilities of $0.9 million that resulted in a net gain of $0.1 million that is recorded in impairment, loss on disposal of property and equipment and shop closures. Upon termination of the leases during the 26 weeks ended June 27, 2021, we derecognized ROU assets of $1.4 million and lease liabilities of $1.6 million that resulted in a net gain of $0.1 million that is recorded in impairment, loss on disposal of property and equipment and shop closures.

Certain of our operating lease agreements include variable payments that are passed through by the landlord, such as common area maintenance and real estate taxes, as well as variable payments based on percentage rent for certain of our shops. Pass-through charges and payments based on percentage rent are included within variable lease cost.

Supplemental disclosures of cash flow information related to leases were as follows:

As of June 27, 2021, we had 0 real estate leases entered into that had not yet commenced.

the "Prior Credit Agreement") with JPMorgan. The Credit Agreement provided, among other things, for a revolving credit facility in a maximum principal amount $40 million, with possible future increases of up to $20 million under an expansion feature. Borrowings under the credit facility generally bear interest at our option at either (i) a eurocurrency rate determined by reference to the applicable LIBOR rate plus a specified margin or ~~an effective tax~~(ii) a prime rate as announced by JP Morgan plus a specified margin. The applicable margin was determined based upon our consolidated total leverage ratio. On the last day of ~~33.5%,~~each calendar quarter, we were required to pay a commitment fee of 0.20% per annum in respect of any unused commitments under the credit facility. So long as certain total leverage ratios, EBITDA thresholds and minimum liquidity requirements are met and no default or event of default has occurred or would result, there was no limit on the “restricted payments” (primarily distributions and equity repurchases) that we may make, provided that proceeds of the loans under the Credit Agreement may not be used for purposes of making restricted payments.

As disclosed in our Annual Report on Form 10-K for the ~~39 weeks~~fiscal year ended ~~September 24, 2017, compared~~December 27, 2020, during 2020, we drew on the credit facility to ~~income tax expense~~increase our cash position and preserve financial flexibility in light of ~~$3.7 million on pre-tax income of $10.1 million, or an effective tax rate of 36.8%, for~~ the ~~39 weeks ended September 25, 2016. The effective tax rate differed~~uncertainty resulting from the ~~federal statutory~~COVID-19 pandemic, and we amended the Credit Agreement throughout fiscal year 2020.

Most recently, we entered into Amendment No. 5 (the “Fifth Amendment”) to the Credit Agreement on February 26, 2021. As a result of the Amendment (i) the maturity date was extended from March 31, 2022 to January 31, 2023, (ii) the revolving credit commitment decreased from $40 million to $25 million, (iii) the interest rate ~~primarily due~~margin with respect to ~~a change~~any Commercial Bank Floating Rate Loan increased to 2.75%, (iv) the interest rate margin with respect to any Eurodollar Loan increased to 5.00%, (v) the definition of EBITDA was amended to exclude non-cash charges/gains in ~~earnings and~~connection with certain equity interests of the ~~adoption of ASU 2016-09, which had an unfavorable impact~~Company, (vi) certain borrowing conditions relating to the Company’s ~~tax~~Consolidated Cash Balance were instituted, (vii) the Company is permitted to repurchase/redeem its equity interests under certain conditions and (viii) the minimum monthly EBITDA and Liquidity thresholds the Company must maintain were revised.

As of June 27, 2021, we had $786 thousand outstanding under the Credit Agreement. As of December 27, 2020, we had $6.3 million outstanding under the Credit Agreement. We are currently in compliance with all financial debt covenants.

On August 10, 2020, PSW, an indirect subsidiary of the Company, entered into a loan agreement with Harvest Small Business Finance, LLC in the aggregate amount of $10.0 million (the “Loan”), pursuant to the PPP under the CARES Act. The Loan was necessary to support our ongoing operations due to the economic uncertainty resulting from the COVID-19 pandemic and lack of access to alternative sources of liquidity.

The Loan is scheduled to mature five years from the date on which PSW applies for loan forgiveness under the CARES Act, bears interest at a rate ~~benefit~~ of ~~7.5%~~1% per annum and is subject to the terms and conditions applicable to loans administered by the U.S. Small Business Administration under the CARES Act. The PPP provides that the use of the Loan amount shall be limited to certain qualifying expenses and may be partially or wholly forgiven in accordance with the requirements set forth in the CARES Act. We have used all of the PPP proceeds toward qualifying expenses and are pursuing forgiveness of the full Loan amount, but we are not able to determine the likelihood or the amount of forgiveness that will be obtained.

We have recorded the amount of the Loan as long-term debt in our condensed consolidated balance sheet as of June 27, 2021, net of the current portion of the Loan which represents the payments that would be due in the next twelve months if we are not able to obtain forgiveness. The related interest has been recorded to interest expense in our condensed consolidated statement of operations for the 13 and 26 weeks ended ~~September 24, 2017 and an unfavorable impact of 38.9% for the 39 weeks ended September 24, 2017.~~ ~~See Note 1 for additional information regarding the adoption of ASU 2016-09.~~

On November 3, 2020, as part of our COVID-related cost reduction efforts and to better align our general and administrative expenses with future strategy, we made the determination to reorganize and restructure our corporate team. We expect that this restructuring plan will result in annual general and administrative expense savings of $3.5 to $4.0 million. This was accomplished through corporate expense optimization, consolidating our shop support services, and through other expense and staff reductions. As a result, we reduced corporate employment levels by approximately 35 employees in the fourth quarter of 2020. We substantially completed our planned restructuring actions during 2020, but we will continue to evaluate our cost structure and seek opportunities for further efficiencies and cost savings as part of our ongoing strategy. As such, we may incur additional restructuring related charges or adjustments to previously recorded charges in the future, however, we are unable to estimate the amount of charges at this time.

The accrued restructuring balances as of June 27, 2021 represent expected future cash payments required to satisfy our remaining obligations, which are expected to be paid throughout 2021.

On February 9, 2021, we closed on a Securities Purchase Agreement (the “SPA”) for ~~approximately $8.9 million, including cost and commission, in open market transactions. As~~the sale by us of ~~September 24, 2017, the remaining dollar~~3,249,668 shares of our common stock at a par value of ~~authorization under the~~$0.01 per share ~~repurchase program was $18.8 million, which does not include commission.

The warrants are initially exercisable commencing August 13, 2021 through their expiration date of August 12, 2026. The proceeds received from the SPA were allocated between shares and warrants based on their relative fair values at closing. The warrants were valued utilizing the Black-Scholes method.

Participants are entitled to receive a specified number of shares of our common stock contingent on achievement of a stock return on our common stock.

On January 30, 2020, the WHO announced a global health emergency because of 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. The COVID-19 pandemic has significantly impacted economic conditions in the United States where all our shops are located. In response to the pandemic, many states and jurisdictions in which we operate issued stay-at-home orders and other measures aimed at slowing the spread of the coronavirus, resulting in significant changes to our operations and a sudden and drastic decrease in revenues. While the pandemic continues to have an impact on our business, the distribution of COVID-19 vaccines and a decline in positive cases and hospitalizations has resulted in a gradual improvement in our sales during the first half of 2021. Nearly all of our shops have reopened their dining rooms and are no longer subject to operating restrictions and capacity limits related to COVID-19. We continue to follow guidance from local authorities in determining the appropriate restrictions to put in place for each shop, including the suspension or reduction of in-shop dining if required due to changes in the pandemic response in each jurisdiction.

The COVID-19 pandemic has adversely affected, and will continue to adversely affect, our operations and financial results for the foreseeable future. There are many uncertainties regarding the current COVID-19 pandemic, and we are closely monitoring the impact of the pandemic on all aspects of our business, including how it will impact our customers, employees, suppliers, vendors, business partners, and distribution channels. We are unable to predict the impact that COVID-19 will have on our financial position and operating results due to numerous uncertainties, however, we are continually assessing the evolving impact of the COVID-19 pandemic and intend to make adjustments to our responses accordingly.

As the COVID-19 pandemic emerged, our first priority was and continues to be ensuring the health and safety of our employees as we serve our customers and communities. We continue to adhere to our stringent food safety and quality assurance programs. We have implemented strict sanitation protocols for our shops including disinfecting high-touch areas and providing tamper-evident stickers on all pickup and delivery orders. We are monitoring recommendations from the Centers for Disease Control and will make necessary adjustments to align with emerging best practices. We have been in regular contact with our supply chain partners and we have not experienced, nor do we foresee, material disruptions in our supply chain. As of June 27, 2021, 6 of our shops remain temporarily closed.

Revenue – Many of our shops, specifically those in suburban and urban residential locations are now operating near or above pre-COVID-19 levels, but other shops, especially those in central business districts, are still operating materially below those levels. While the majority of our shops have reopened their dining rooms and are operating without mandated restrictions, we continue to offer convenient off-premise options for customers. Customers can place off-premise orders through Potbelly.com and the Potbelly app, or through DoorDash, Grubhub, Postmates, Uber Eats and other marketplaces nationwide. We continue to evaluate our product offerings and service methods to ensure we are aligned with the preferences of our customers as the pandemic evolves.

Operating Costs – We implemented measures to reduce operating costs and general and administrative expenses in response to the negative impact the pandemic has had on our business. We continually adjust shop-level labor and purchases of inventory to align with current levels of demand. At the onset of the pandemic, we implemented a strategy to reduce costs and preserve cash, and we continue to be thoughtful and judicious regarding our operating expenses during the uncertainty of the pandemic. Additionally, we announced a corporate restructuring plan that was executed during the fourth quarter of 2020 that is expected to reduce annual general and administrative expenses by $3.5 million to $4.0 million. The Plan consisted of corporate expense optimization, consolidation of shop support services, and other expense and staff reductions.

In fiscal year 2020, we suspended the payment of rent on the majority of our leases and entered into discussions with our landlords regarding the restructuring of those leases in light of various contractual and legal defenses. As of June 27, 2021, we have

amended approximately 342 of the lease agreements for our shops, which include rent abatements, rent deferrals, and/or modified lease terms to reduce ongoing rent, and we have completed early terminations of leases for 30 of our shops. The vast majority of these lease amendments were completed during fiscal year 2020, and we are substantially complete with COVID-19-related lease amendments as of June 27, 2021.

Shop Development – We halted capital investment in new company-owned shops, except for shops that were substantially complete, as well as all non-essential capital expenditures. We do not have plans to begin construction on any company-owned shops until the impact of the pandemic is behind us.

We will continue to actively monitor the evolving situation and may take further actions that alter our business operations as may be required by federal, state or local authorities or that we determine are in the best interests of our employees, customers, franchisees, stakeholders and communities.

In the third quarter of 2017 Potbelly experienced temporary shop closures in Texas due to Hurricane Harvey. In total, 22 shops were affected, with one shop being significantly damaged. Included within Potbelly’s Condensed Consolidated Statements of Operations within impairment and loss on disposal of property and equipment, impairment charges of $0.7 were million recorded in relation to this shop, with insurance recoveries of $0.7 million also recorded within the same caption.

The revenue growth~~June 28, 2020. This increase was primarily driven by the easing of the government restrictions previously imposed by federal, state and local governments, as a result of the COVID-19 pandemic. This resulted in an increase ~~in sales~~for the quarter of ~~$9.5~~$38.1 million, ~~from shops not yet~~or 70.0%, in ~~our~~ company-operated comparable store ~~sales base and an increase~~sales. The increases in sales during the second quarter of ~~$0.2~~2021 also included sales of $3.9 million due to shops that were temporarily closed in the prior year and have since reopened, partially offset by shops that have permanently closed in the last year. Additionally, revenue from franchise royalties and ~~fees.

The ultimate severity and longevity of the ~~carrying amount~~COVID-19 pandemic is unknown, and therefore, it is possible that impairments could be identified in future periods, and such amounts could be material.

During the 13 weeks ended June 27, 2021, we terminated 1 lease. We incurred $0 million in lease termination fees related to the lease for the 13 weeks ended June 27, 2021. Upon termination of the lease during the 13 weeks ended June 27, 2021, we derecognized ROU assets of $0.8 million and lease liabilities of $0.9 million that resulted in a net gain of $0.1 million that is recorded in impairment, loss on ~~our balance sheet over the shops’ estimated fair value. We perform impairment analyses on a quarterly basis which involve significant judgment by management including estimates~~disposal of ~~future cash flows~~property and future growth rates, among other assumptions.

We recognized income tax expense of $41 thousand for the 13thirteen weeks ended September 25, 2016, primarily attributable to lower pre-tax book income and certain tax benefits. The decrease was partially offset by the adoption of Accounting Standards Update (ASU) 2016-09, which resulted in the tax effects of equity-based compensation being recorded through the income statement rather than equity. For the 13 weeks ended September 24, 2017, the effective tax rate was 80.4%, compared to 34.2% for the 13 weeks ended September 25, 2016. The increase in the effective tax rate was driven by lower pre-tax book income and certain tax benefits ~~partially offset by~~ ~~the net effect of the adoption of ASU 2016-09 for stock-based compensation, which impacted our tax rate by 7.5%.~~ ~~See Note 1 to the Condensed Consolidated Financial Statements for additional information regarding the adoption of ASU 2016-09.~~June 28, 2020.

Upon termination of leases during the 26 weeks ended June 27, 2021, we derecognized ROU assets of $1.4 million and lease liabilities of $1.6 million that resulted in a net gain of $0.1 million that is recorded in impairment, loss on disposal of property and equipment and shop closures.

During the first quarter of 2021, we amended the lease for our ~~balance sheet over~~corporate Support Center office in Chicago to relocate to a different office space. As a result of this relocation, the ~~shops’ estimated fair value. We perform impairment analyses~~leasehold improvements of the original office space were disposed, resulting in a loss on ~~a quarterly basis which involve significant judgment by management including estimates~~disposal of future cash flows and future growth rates, among other assumptions. Based on our current projections, no impairment, beyond what has already been recorded, has been identified. However, given the current challenges facing the industry and our business, future evaluations could result in additional impairment charges.$2.5 million.

~~Interest~~Net interest expense was ~~$101~~$472 thousand during the 3926 weeks ended ~~September 24, 2017~~June 27, 2021 and ~~$102~~$462 thousand during the 3926 weeks ended ~~September 25, 2016.~~June 28, 2020.

We recognized an income tax benefit of $3.7 million for the 3926 weeks ended ~~September 25, 2016,~~June 28, 2020 primarily ~~attributable~~due to ~~lower pre-tax book income and certain~~a discrete tax ~~benefits.

The decrease in~~carryback of NOLs and a refund of prior AMT credits allowed under the ~~effective tax rate was primarily driven by lower pre-tax book income and certain tax benefits~~ ~~partially offset by~~ ~~the net effect of the adoption of ASU 2016-09 for stock-based compensation, which increased our tax rate by approximately 38.9%.~~ ~~See Note 1 to the Condensed Consolidated Financial Statements for additional information regarding the adoption of ASU 2016-09.~~CARES Act.

~~Our~~Potbelly’s ongoing primary sources of liquidity and capital resources are cash provided from operating activities, existing cash and cash equivalents, and our credit facility. ~~Our~~Potbelly’s primary requirements for liquidity and capital are new shop openings, existing shop capital investments, ~~(maintenance and improvements), repurchases of our common stock,~~maintenance, lease obligations, ~~purchases of existing franchise-operated shops~~working capital and general corporate needs. ~~Our~~Potbelly’s requirement for working capital is not significant since our customers pay for their food and beverage purchases in cash or payment cards (credit or debit) at the time of sale. ~~Therefore, we are~~Thus, Potbelly is able to sell certain inventory items before we ~~have~~need to pay our ~~suppliers. Our~~suppliers for such items. Company shops do not require significant inventories or receivables.

The COVID-19 pandemic’s impact on our operations and revenues had significantly affected our ability to generate cash from operations in 2020. To preserve financial flexibility, we have utilized our revolving credit facility to fund operations.

We ended the second quarter of 2021 with a cash balance of $11.8 million and total liquidity (cash plus amounts available on our Revolving Credit Facility) of $35.3 million compared to a balance of $11.5 million and total liquidity of $33.5 million at the end of the previous quarter. We believe that ~~these sources of liquidity~~cash from our operations and ~~capital~~borrowings under our revolving credit facility will be able to provide sufficient ~~to finance our continued operations and expansion plans~~liquidity for at least the next twelve months.

On February 9, 2021, we closed on a Securities Purchase Agreement (the “SPA”) for the sale of 3,249,668 shares of our common stock at a par value of $0.01 per share and the issuance of warrants to purchase 1,299,861 shares of common stock at an exercise price of $5.45 per warrant for gross proceeds of $16.0 million, before deducting placement agent fees and offering expenses of approximately $1.0 million. The warrants are initially exercisable commencing August 13, 2021 through their expiration date of August 12, 2026.

The following table presents summary cash flow information for the periods indicated (in thousands):

Net cash ~~provided by~~used in operating activities ~~decreased~~increased to ~~$28.4~~$5.5 million for the 3926 weeks ended ~~September 24, 2017,~~June 27, 2021, from ~~$33.6~~cash used in operating activities of $4.9 million for the 3926 weeks ended ~~September 25, 2016.~~June 28, 2020. The ~~$5.2~~$0.6 million ~~decrease~~change in operating cash was primarily driven by ~~changes~~the timing of payment for certain liabilities, including the deferral of rent for many of our shops in ~~certain working capital accounts mainly due to timing. The remainder~~the prior year. Approximately $3.7 million of deferred rent from 2020 was repaid in the ~~difference~~26 weeks ended June 27, 2021.

The ~~decrease~~$13.0 million change in ~~net~~financing cash ~~used~~ was primarily driven by ~~$8.9 million of treasury stock repurchased during~~net borrowings under the ~~39 weeks ended September 24, 2017, compared to $20.4 million during~~Credit Facility, partially offset by the ~~39 weeks ended September 25, 2016. Additionally, Potbelly received $3.2 million in~~net proceeds from the ~~exercise~~SPA.

On August 7, 2019, we entered into a second amended and restated revolving credit facility agreement (the "Credit Agreement") with JPMorgan Chase Bank, N.A. (“JPMorgan”) that expires in July 2022. The Credit Agreement amends and restates that certain amended and restated revolving credit facility agreement, dated as of ~~stock options~~December 9, 2015, and ~~warrants during~~amended on May 3, 2019 (collectively, the 39"Prior Credit Agreement") with JPMorgan. The Credit Agreement provided, among other things, for a revolving credit facility in a maximum principal amount $40 million, with possible future increases of up to $20 million under an expansion feature. Borrowings under the credit facility generally bear interest at our option at either (i) a eurocurrency rate determined by reference to the applicable LIBOR rate plus a specified margin or (ii) a prime rate as announced by JP Morgan plus a specified margin. The applicable margin was determined based upon our consolidated total leverage ratio. On the last day of each calendar quarter, we were required to pay a commitment fee of 0.20% per annum in respect of any unused commitments under the credit facility. So long as certain total leverage ratios, EBITDA thresholds and minimum liquidity requirements are met and no default or event of default has occurred or would result, there was no limit on the “restricted payments” (primarily distributions and equity repurchases) that we may make, provided that proceeds of the loans under the Credit Agreement may not be used for purposes of making restricted payments.

As disclosed in our Annual Report on Form 10-K for the fiscal year ended December 27, 2020, we drew on the credit facility to increase our cash position and preserve financial flexibility in light of the uncertainty resulting from the COVID-19 pandemic, and we amended the Credit Agreement throughout fiscal year 2020.

Most recently, we entered into Amendment No. 5 (the “Fifth Amendment”) to the Credit Agreement on February 26, 2021. As a result of the Amendment (i) the maturity date was extended from March 31, 2022 to January 31, 2023, (ii) the revolving credit commitment decreased from $40 million to $25 million, (iii) the interest rate margin with respect to any Commercial Bank Floating Rate Loan increased to 2.75%, (iv) the interest rate margin with respect to any Eurodollar Loan increased to 5.00%, (v) the definition of EBITDA was amended to exclude non-cash charges/gains in connection with certain equity interests of the Company, (vi) certain borrowing conditions relating to the Company’s Consolidated Cash Balance were instituted, (vii) the Company is permitted to repurchase/redeem its equity interests under certain conditions and (viii) the minimum monthly EBITDA and Liquidity thresholds the Company must maintain were revised.

As of June 27, 2021, we had $786 thousand outstanding under the Credit Agreement. As of June 27, 2020, we had $23.1 million outstanding under the Credit Agreement. We are currently in compliance with all financial debt covenants.

The Loan is scheduled to mature five years from the date on which PSW applies for loan forgiveness under the CARES Act, bears interest at a rate of 1% per annum and is subject to the terms and conditions applicable to loans administered by the U.S. Small Business Administration under the CARES Act. The PPP provides that the use of the Loan amount shall be limited to certain qualifying expenses and may be partially or wholly forgiven in accordance with the requirements set forth in the CARES Act. We have used all of the PPP proceeds toward qualifying expenses and are pursuing forgiveness of the full Loan amount, but we are not able to determine the likelihood or the amount of forgiveness that will be obtained.

We have recorded the amount of the Loan as long-term debt in our condensed consolidated balance sheet as of June 27, 2021, net of the current portion of the Loan which represents the payments that would be due in the next twelve months if we are not able to obtain forgiveness. The related interest has been recorded to interest expense in our condensed consolidated statement of operations for the 13 and 26 weeks ended ~~September 24, 2017, compared to $5.7 million during the 39 weeks ended September 25, 2016.~~June 27, 2021.

On ~~September~~May 8, ~~2016, the Company~~2018, we announced that ~~its~~our Board of Directors authorized a ~~share~~stock repurchase program offor up to ~~$30.0~~$65.0 million of ~~the Company’s~~our outstanding common stock.

Purchases may be started or stopped at any time without prior notice depending on market conditions and other factors. Repurchased shares are included as treasury stock in the condensed consolidated balance sheets and the condensed consolidated statements of equity.

~~On December 9, 2015,~~For the 26 ended June 27, 2021, we entered into an amended and restated five-year revolving credit facility agreement that expires in November 2020.

Borrowings under the credit facility generally bear interest~~our stock repurchase program at our option at either (i) a eurocurrency rate determined by reference to the applicable London Interbank Offered Rate (LIBOR) plus a margin ranging from 1.00% to 1.75% or (ii) a prime rate as announced by JP Morgan Chase plus a margin ranging from 0.00% to 0.50%. The applicable margin is determined based upon our consolidated total leverage ratio. On the last day of each calendar quarter, we are required to pay a commitment fee ranging from 0.125% to 0.20% per annum in respect of any unused commitments under the credit facility, with the specific rate determined based upon our consolidated total leverage ratio. So long as the leverage ratios are met, there is no limit on the “restricted payments” (primarily distributions and equity repurchases) that we may make. As of September 24, 2017, we had no amounts outstanding under the credit facility.this time.

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. 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. Critical accounting policies are those that management believes are both most important to the portrayal of our financial condition and operating results and require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. We base ~~our~~ estimates on historical experience and other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Judgments and uncertainties affecting the application of those policies may result in materially different amounts being reported under different conditions or using different assumptions. WePotbelly had no significant changes in our critical accounting estimates since ~~our~~the last annual report. Our critical accounting estimates are identified and described in our annual consolidated financial statements and related notes.

As of ~~September 24, 2017,~~June 27, 2021, we do not have any off-balance sheet arrangements, synthetic leases, investments in special purpose entities or undisclosed borrowings or debt that would be required to be disclosed pursuant to Item 303 of Regulation S-K under the Exchange Act.

See Note 1 to the Consolidated Financial Statements for a description of recently issued Financial Accounting Standards.
