Jackson Property Ltd. is a leading builder of luxury houses in New Zealand. It operates its business in a building in downtown Auckland City. The building was built in 1949 at a cost of $500,000 and is fully depreciated so that it is shown on the company's balance sheet at a nominal value of $1.00. The land on which the building was built in 1949 was purchased in 1948 for $1,000,000. The company does not charge depreciation or appreciation on the value of the land for balance sheet purposes. The franchise, which is the company's only other major investment, cost $100,000 in 1949. The franchise cost has now been fully amortized. The current assessed value of the building is $100,000. The assessed value of the land, which is located in a prime urban area, is $20,000,000 and reflects the net value of the property if the current building is demolished and replaced with an office and shopping complex. The company adopts a traditional performance evaluation system.
