ARGs operations could be influenced by weather conditions.
Weather, which is unpredictable, can impact Arbys restaurant sales. Harsh weather conditions that keep customers from dining out result in lost opportunities for Arbys restaurants. A heavy snowstorm in the Northeast or Midwest or a hurricane in the Southeast can shut down an entire metropolitan area, resulting in a reduction in sales in that area. Our first quarter includes winter months and historically has a lower level of sales at company-owned restaurants. Because a significant portion of ARGs restaurant operating costs is fixed or semi-fixed in nature, the loss of sales during these periods hurts ARGs operating margins, and can result in restaurant operating losses. For these reasons, a quarter-to-quarter comparison may not be a good indication of ARGs performance or how it may perform in the future.
