Mike's Bikes uses a perpetual inventory system At December 31, the perpetual inventory records indicate the following quantities of a particular bike: Unit Total Quantity Cost Cost First purchase (oldest) 100 $130 $13,000 Second purchase.. 130 140 18,200 Third purchase.. 70 150 10,500 Total . 300 $41,700 A year-end physical inventory, however, shows only 290 of these bikes on hand. In its financial statements, Mike's values its inventories at the lower-of-cost-or-market. At year-end, the per-unit replacement cost of this tree is $155. Instructions Prepare the journal entries required to adjust the inventory records at year-end assuming that: a. Mike's uses 1. Average cost 2 Last-in, first-out b. Mike's uses the first-in, first-out method. However, the replacement cost of the bikes at year-end is $120 apiece, rather than $155 stated originally. (Make separate journal entries to record (1) the shrinkage losses and (2) the restatement of the inventory at a market value lower than cost. Record the shrinkage losses fist.) C. Assume that the company had been experiencing monthly inventory shrinkage of 20 to 30 bikes for several months In response, management placed several hidden security cameras throughout the premises Within days an employee was caught on film loading bikes into his pickup truck. The employee's attorney asked that the case be dropped because the company had " unethically used a hidden camera to entrap his client." Do you agree with the attorney? Defend your
