The extent of the impact of the COVID-19 pandemic on our business is highly uncertain and difficult to predict, as the response to the pandemic varies by state and municipalities within states. In the last five weeks of the quarter we experienced a significant reduction in guest traffic at our restaurants due to changes in consumer behavior as social distancing practices, dining room closures and other restrictions as have been mandated or encouraged by federal, state and local governments. During the COVID-19 impacted weeks, substantially all of our restaurants remained open, with dining rooms closed and all locations operating in an off-premise capacity, which represents close to 90% of the Company’s business historically, including drive-thru, third-party delivery, and carry-out. </span></div><div style="text-align:justify;margin-top:6pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">Our operating results substantially depend upon our franchisees’ sales volumes, restaurant profitability, and financial stability. The financial impact of COVID-19 has had, and is expected to continue to have, an adverse effect on our franchisees’ liquidity and we are working closely with our franchisees to monitor and assist them with access to appropriate sources of liquidity in order to sustain their businesses throughout this crisis. </span></div>We cannot currently estimate the duration or future negative financial impact of the COVID-19 pandemic on our business. Ongoing material adverse effects of the COVID-19 pandemic on company-owned and franchised restaurants for an extended period could negatively affect our operating results, including reductions in revenue and cash flow and could impact our impairment assessments of accounts receivable, long-lived assets, operating lease assets, and/or goodwill.
