T-Shirts R Us Inc T-Shirts R Us Inc $\text { Liquidation Value }$

T-shirts R Us Inc. operates two divisions that each manufactures t-shirts for universities. Each division has its own manufacturing facility. The historical-cost accounting system reports the following financial data for 2019. $$\begin{array} { | l | r | r | } \hline { \text { Atlantic Coast Division } } \\\text { Income Statement (000s) } \\\hline \text { Revenues } & & \$ 600 \\\hline \text { Operating Costs } & & 470 \\\hline \text { Operating Income } & & \$ 130 \\\hline { \text { Big-10 Division } } \\{ \text { Income Statement (000s) } } \\\hline \text { Revenues } & & \$ 600 \\\hline \text { Operating Costs } & & \underline { 400 } \\\hline \text { Operating Income } & & \$ 200 \\\hline\end{array}$$ T-shirts R Us Inc. estimates the useful life of each manufacturing facility to be 15 years. The company uses straight line depreciation, with a depreciation charge of $70,000 per year for each division and no salvage value at the end of 15 years. The manufacturing facility is the only long-lived asset of either division. Current assets are $300,000 in each division. At the end of 2019 the Atlantic Coast Division is 4 years old and the Big-10 Division is 6 years old. An index of construction costs, replacement cost, and liquidation values for manufacturing facilities used in the production of t-shirts for the 7-year period that T-shirts R Us Inc. has been operating, are as follows: $\text { Liquidation Value }$
$\begin{array}{cccccc}\hline&&\text { Replacement }\\\text { Year } & \text { Cost Index } & \text { Cost } & \text { Atlantic Coast } & \text { Big 10 } \\2013 & 80 & \$ 1,000,000 & \$ 800,000 & \$ 800,000\\2014 & 82 & 1,000,000 & 800,000 & 800,000 \\2015 & 84 & 1,100,000 & 700,000 & 700,000 \\2016 & 89 & 1,150,000 & 700,000 & 600,000\\2017 & 94 & 1,200,000 & 800,000 & 600,000 \\2018 & 96 & 1,250,000 & 900,000 & 600,000 \\2019 & 100 & 1,300,000 & 1,000,000 & 500,000\end{array}$ Required:
