Short Answer

(Depletion Computations—Oil) Diderot Drilling Company has leased property on which oil has been discovered. Wells on this property produced 18,000 barrels of oil during the past year that sold at an average sales price of $55 per barrel. Total oil resources of this property are estimated to be 250,000 barrels.

The lease provided for an outright payment of $500,000 to the lessor (owner) before drilling could be commenced and an annual rental of $31,500. A premium of 5% of the sales price of every barrel of oil removed is to be paid annually to the lessor. In addition, Diderot (lessee) is to clean up all the waste and debris from drilling and to bear the costs of reconditioning the land for farming when the wells are abandoned. The estimated fair value, at the time of the lease, of this clean-up and reconditioning is $30,000.


From the provisions of the lease agreement, you are to compute the cost per barrel for the past year, exclusive of operating costs, to Diderot Drilling Company. (Round to the nearest cent.)

The total cost per barrel is $6.62.

(Depreciation—Strike, Units-of-Production, Obsolescence) The following are three different and unrelated situations involving depreciation accounting. Answer the question(s) at the end of each situation.

Situation I: Recently, Broderick Company experienced a strike that affected a number of its operating plants. The controller of this company indicated that it was not appropriate to report depreciation expense during this period because the equipment did not depreciate and an improper matching of costs and revenues would result. She based her position on the following points.

1. It is inappropriate to charge the period with costs for which there are no related revenues arising from production.

2. The basic factor of depreciation in this instance is wear and tear. Because equipment was idle, no wear and tear occurred.


Comment on the appropriateness of the controller’s comments.

Situation II: Etheridge Company manufactures electrical appliances, most of which are used in homes. Company engineers have designed a new type of blender which, through the use of a few attachments, will perform more functions than any blender currently on the market. Demand for the new blender can be projected with reasonable probability. In order to make the blenders, Etheridge needs a specialized machine that is not available from outside sources. It has been decided to make such a machine in Etheridge’s own plant.


  1. Discuss the effect of projected demand in units for the new blenders (which may be steady, decreasing, or increasing) on the determination of a depreciation method for the machine.
  2. What other matters should be considered in determining the depreciation method? (Ignore income tax considerations.)

Situation III: Haley Paper Company operates a 300-ton-per-day kraft pulp mill and four sawmills in Wisconsin. The company is in the process of expanding its pulp mill facilities to a capacity of 1,000 tons per day and plans to replace three of its older, less efficient sawmills with an expanded facility. One of the mills to be replaced did not operate for most of 2017 (current year), and there are no plans to reopen it before the new sawmill facility becomes operational.

In reviewing the depreciation rates and discussing the salvage values of the sawmills that were to be replaced, it was noted that if present depreciation rates were not adjusted, substantial amounts of plant costs on these three mills would not be depreciated by the time the new mill came on stream.


What is the proper accounting for the four sawmills at the end of 2017?
