Subway Sandwiches operates a fast-casual sandwich chain in California. The company's first location, SFO, was opened in 2018. The Sanjose and LA locations followed suit in 2019. Operations are heavily decentralized and store managers are evaluated on their return on investment (ROI) with corporate expecting them to achieve at least a 20% ROI. (As explained below, Subway calculates ROI as the controllable margin of the store in a period divided by the total assets at the end of the period.) The company is considering changing its performance evaluation system to an EVA approach. Data for 2021 is provided below:

The company currently borrows at 6% per year on its long-term debt and pays a 20% tax rate on income.

a)For each of the stores, calculate 2021 ROI using controllable margin as the numerator measure of income and total assets at year-end as the denominator measure of investment.

b)During a metro-wide managers meeting, Michael Scott, the company's financial controller suggests using "current cost" accounting to calculate the ROI saying "Inflation is here, lease costs in California have gone up almost 15% from last year. We should revalue the long-term assets on the balance sheet, which mainly consists of the capitalized lease assets, to reflect what it would take in investment to operate this business if we started today". Suppose Subway Sandwiches adjusts the long-term assets (assumed to be all capitalized leases) on the balance sheet upwards by 15% as he suggests:

i) What is the new ROI for all three locations and what effect would this accounting change have on the 2021 ROI for the three stores

ii) If store manager bonuses are conditional on achieving the 20% ROI earmarked by corporate, which manager would be most strongly opposed to this change? Briefly explain
