The company has an order from a customer to produce an alloy that contains four metals according to the following specifications: at least 21% of metal A, no more than 12% of metal B, no more than 7% of metal C and between 30% and 65% of metal D. The proportion of the four metals in each of the six ores and the level of impurities in each ore are provided in the following table: Ore Metal (%) Impurities (%) Cost/Ton A B C D 1 19 15 12 14 40 27 2 43 10 25 7 15 25 3 17 0 0 53 30 32 4 20 12 0 18 50 22 5 0 24 10 31 35 20 6 12 18 16 25 29 24 When the metals are processed and refined, the impurities are removed.

It is up to the congressman to decide how to distribute the money. The congressman has decided to allocate the money to four ongoing programs because of their importance to his district – a job training program, a parks project, a sanitation project, and a mobile library. However, the congressman wants to distribute the money in a manner that will please the most voters, or, in other words, gain him the most votes in the upcoming election. His staff’s estimates of the number of votes gained per dollar spent for the various programs are as follows.

Peary and his wife, Josie J. Peary. The corporation manufactures a cordless handheld heated blower that melts snow and ice from car windshields. The device uses a 21 volt rechargeable battery (business activity code number 339900). The corporation has reported positive financial and taxable incomes since inception. The company is located at 200 Snowcap Way, Denali, Alaska 99502. The company’s employer identification number is 98-7654321, and the calendar year is used for tax purposes. The date of incorporation was March 14, 2007. Rupert M. Peary (social security number 111-11-1111) is an 80 percent shareholder and president of the company. Josie J. Peary (social security number 123-45-6789) is a 20 percent shareholder and vice president of the company. Both persons devote 100 percent of their time to the corporation. Rupert’s compensation is $138,326 per year, and Josie’s compensation is $76,848 per year. The corporation is not a personal holding company. While the corporation is a ‘closely-held C corporation,’ it does not engage in activities to which the at-risk or passive activity loss limitations apply. The corporation files its tax return on the accrual method. Inventory has been consistently valued at cost under the FIFO method using the full absorption procedure. Inventory capitalization rules of Internal Revenue Code Section 263A do not apply due to the ‘small business exception’ (average annual gross receipts for the three preceding taxable years do not exceed $10 million). The accounting records are computerized. The corporation’s audited income statement and balance sheet for the current year, prepared by the accounting firm of Bering & Beaufort, CPAs, follow: NO MORE ICE, INC.
