PTGC Ltd has been awarded the contract to carry out a residential subdivision installation and need an additional compressor for an estimated nine months. The purchase price of the compressor is $56,000 and it is estimated that it can be sold at the end of the period for $40,000.

Should the company decide to buy the compressor, it would be required to pay an annual insurance premium of $3,000; one quarter will be recoverable at the end of the nine months. In addition, maintenance costing $300 will have to be carried out at the end of each month, except for the ninth month when a major overhaul costing $1,000 is needed to prepare it for sale.

The company has been offered an operating lease of the same compressor by Hedley Leasing Ltd at monthly rentals of $3,300 payable in advance.

The company tax rate is 30% and PTGC Ltd can borrow at an after tax rate of 12% per annum.

Assume that tax savings are obtained immediately except for depreciation, in which case savings are obtained at the end of the ninth month.
