Use Segment Information to Refine Sales Forecast To forecast sales growth for FY2018 for a publicly traded company in the retail sector, we begin with the following historical sales information. $ millions 2017 2016 2015 2014 2013 Net sales. ................ $46,021 $39,865 $37,536 $36,012 $34,553 Require a. Determine the sales-growth rate (in percentage) for 2014 to 2017. What trend do we observe? b. If we were to use the four-year average sales growth to forecast 2018 sales, what rate would we use? c. The annual report reveals that 2016 included a 53rd week (as is common for retailers, every four years) and that the company acquired a smaller company during that year. Sales for the newly ac- quired company were included in the consolidated income statement from the date of acquisition, which amounted to $5,235 million. Use this information to refine the sales-growth rate. (Hint: Consider multiplying sales for a 53-week year by 52/53 to get an apples-to-apples comparison with numbers from 52-week years.)
