Dunedin Ltd acquired two new machines for cash on 1 January 2023. The cost of machine A was \($400\) 000, and of machine B, \($600\) 000. Each machine was expected to have a useful life of 10 years, and residual values were estimated at \($20\) 000 for machine A and \($50\) 000 for machine B.

Because of technological advances, Dunedin Ltd decided to replace machine A. It traded in machine A on 31 March 2027 for a new machine, C, which cost \($420\) 000. A \($200\) 000 trade-in was allowed for machine A, and the balance of machine C’s cost was paid in cash. Machine C was expected to have a useful life of 8 years and a residual value of \($20\) 000.

On 2 July 2027, extensive repairs were carried out on machine B for \($66\) 000 cash. Dunedin Ltd expected these repairs to extend machine B’s useful life by 4 years and it revised machine B’s estimated residual value to \($19\) 500. Machine B was eventually sold on 1 April 2026 for \($300\) 000 cash.
