On June 30, 2011, Sergio Machinery bought the precision laser-guided steel punch which has the expected capacity of 300,000 units and no residual value. Cost of machine was $450,000 and is to be depreciated using units-of-production method. During 6 months of 2011, 24,000 units of product were made. At the starting of 2012, engineers evaluated that machine can realistically be utilized to produce only another 230,000 units. During 2012, 70,000 units were made.
