4-52 Spoilage, Rework and Scrap (30 Min)
1. Normal spoilage is the occurrence of unacceptable units arising under
efficient operating conditions. Normal spoilage is an inherent result of
the particular process or operation and is uncontrollable in the short run.
The costs associated with normal spoilage are typically viewed as part of
the cost of the good units produced.
Abnormal spoilage is spoilage that is not expected to arise under
efficient operating conditions and is not an inherent part of the
2. a. Spoiled units are unacceptable units of production that are either
discarded or sold for disposal value.
b. Rework units are unacceptable units or production that are
subsequently reconditioned into good units which can be sold as
acceptable finished goods.
c. Scrap represents inputs that do not become part of the output and
have minor economic value when compared to the sales value of the
completed product.
3. a. An analysis of the 5,000 units rejected by Richport Company for Job
No. N1192-122 yields the following breakdown between normal and
abnormal spoilage.
Units
Normal spoilage (see below)* 3,000
production = production before any spoilage)
Good Production for 117,000 units = 117,000 / (1-.025)= 120,000 units; if we produced 120,000 units, we would expect a normal
spoilage of 2.5% for a net of 117,000 units; so Normal spoilage = 120,000 x .025 = 3,000 units, or 120,000 – 117,000 = 3,000
