Shah Taylor Company (STC) designs and manufactures T-shirts. The company is a small business that Mr. Shazrul, the founder, developed while in college He began producing t-shirt for friends, hand-printed with college colors and logos. As demand grew, he hired some workers and began to manage the operation Currently, STC sells its T-shirt to brand-name clothes retailers in Melaka The company uses two direct cost categories: direct material and direct labour. For labours, STC has some employees who have been with the company for a very long time and others who are newly joined and inexperienced. The company uses standard costing for the t-shirt cost per unit. A typical standard hour per t-shirt is expected to take 125 hours of labour at the standard wage rate is RM12.00 per hour. The standard material of a t-shirt requires 3 meters of fabric X. The standard price of fabric X used to produce a t-shirt is RM2.30 per meter. The production manager, Mr. John, is responsible for the purchasing of materials and any issues relating to production However, he is not responsible for the setting of standards costs At the end of May 2021, 122,000 units of t-shirt were produced. Direct materials used were 2.8 meters per unit. The actual direct material cost was RM2.46 per meter. The actual direct labor-hours used was 13 hours per unit, at an actual wage of RM12.60 per hour. After the end of May 2021 period, STC decided to revise the standard costs retrospectively to take account of the following: 1. A 3 percent increase in the direct material price per kilogram. 2 A labour rate increase of 4 percent 3. The standard for labour efficiency had anticipated buying a new machine leading to a 10 percent decrease in labour hours; instead of buying a new machine, existing machines had been improved, giving an expected 5 percent saving in material usage.
