Londonderry Lumber Inc. $($Londonderry$)$ purchases logs from independent timber contractors and processes the logs into three types of lumber products. These products are the result of a joint sawmill

process that involves removal of bark from the logs$,$ cutting the logs into a workable size, and then cutting the individual products from the logs$.$

View the per$-$unit information.

The studs are sold as rough$-$cut lumber after emerging from the sawmill operation without further processing by Londonderry. Also, the posts require no further processing beyond the splitoff point. The

decorative pieces must be planed and further sized after emerging from the sawmill. This additional processing costs $$125,000$ per month and normally results in a loss of $10\%$ of the units entering the

process. Without this planing and sizing process, there is still an active intermediate market for the unfinished decorative pieces in which the selling price averages $$70$ per unit.

Required

Based on the information provided for Londonderry Lumber, allocate the joint processing

costs of $$1,010,000$ to the three products using:

a$.$ Sales value at splitoff method

b$.$ Physical$-$measure method $($volume in units$)$

c$.$ NRV method

Prepare an analysis that compares processing the decorative pieces further, as is

current practice, with selling them as a rough$-$cut product immediately at splitoff.

Assume the company announced that in six months it will sell the unfinished decorative

pieces at splitoff due to increasing competitive pressure. Identify at least three types of likely

behaviour that will be demonstrated by the skilled labour in the planing$-$and$-$sizing process as

a result of this announcement. Include in your discussion how this behaviour could be

influenced by management.

Joint Cost Information

The joint process results in the following costs of products for a

typical month:

Direct materials $($rough timber logs$)$

Debarking $($labour and overhead$)$

Sizing $($labour and overhead$)$

Product cutting $($labour and overhead$)$
