2. The information in the cost report shows two relevant items of
information regarding planning for the coming month’s work. First,
note there has been an increase in WIP during November, a month in
which there were fewer units in process (1,350 units) . December’s
work will require 1,500 + 300 = 1,800 units in process, somewhat
larger than November’s requirement. GWI should be concerned
about its capacity and ability to meet the December orders on a

4. The request is a violation of the controller’s responsibility to prepare
accurate production cost reports. The ethical principles of integrity and
objectivity require the controller to use the best available estimate of
percentage completion.
Since there is a high level of ending WIP, the change from 40% to 60%
would have a significant effect on equivalent units and cost per equivalent
unit, as shown below
The weighted-average conversion cost per equivalent unit decreases from

2. On March 9, 2012 the exchange rate was $1 US = 1,116 South Korean
Won (KRW). The dollar had fallen about 15% from a rate of $1 US =
1,253 KRW three years earlier. These economic cycles that affect
currency exchange rates are important in product costing and business
management, as they affect trade between the countries. With the dollar
falling U.S. exports to South Korean are cheaper in Korea, while imports of
Korean goods are more expensive to the U.S. consumer.
