People Able Computer, Inc., with headquarters in San Francisco, manufactures and sells a desktop computer. People Able has three divisions, each of which is located in a different country:
a. China division—manufactures memory devices and keyboards
b. South Korea division—assembles desktop computers using locally manufactured parts, along with memory devices and keyboards from the China division
c. U.S. division—packages and distributes desktop computers Each division is run as a profit center. The costs for the work done in each division for a single desktop computer are as follows:

■ Chinese income tax rate on the China division’s operating income: 40%
■ South Korean income tax rate on the South Korea division’s operating income: 20%
■ U.S. income tax rate on the U.S. division’s operating income: 28%
Each desktop computer is sold to retail outlets in the United States for $3,200. Assume that the current foreign exchange rates are as follows:

8 yuan = $1 U.S.
1,200 won = $ 1 U.S.

Both the China and the South Korea divisions sell part of their production under a private label. The China division sells the comparable memory/keyboard package used in each People Able desktop computer to a Chinese manufacturer for 3,600 yuan. The South Korea division sells the comparable desktop computer to a South Korean distributor for 1,560,000 won.
