Western Manufacturing is involved with several potential contingent liabilities
Western Manufacturing is involved with several potential contingent liabilities. Your assignment is to draft the appropriate accounting treatment for each situation described below. Western’s fiscal year-end is December 31, 2021, and the financial statements will be issued in early February 2022.
a. During 2021, Western experienced labor disputes at three of its plants. Management hopes an agreement will soon be reached. However, negotiations between the company and the unions have not produced an acceptable settlement, and employee strikes are currently under way. It is virtually certain that material costs will be incurred, but the amount of possible costs cannot be reasonably estimated.
b. Western warrants most products it sells against defects in materials and workmanship for a period of a year. Based on its experience with previous product introductions, warranty costs are expected to approximate 2% of sales. A new product introduced in 2021 had sales of $2 million, and actual warranty expenditures incurred so far on the product are $25,000. The only entry made so far relating to warranties on this new product was to debit Warranty Expense $25,000 and credit Cash $25,000.
c. Western is involved in a suit filed in January 2022 by Crump Holdings seeking $88 million, as an adjustment to the purchase price in connection with the company’s sale of its textile business in 2021. The suit alleges that Western misstated the assets and liabilities used to calculate the purchase price for the textile division. Legal counsel advises that it is reasonably possible that Western could lose up to $88 million.
Required:
In a memo, describe the appropriate means of reporting each situation and explain your reasoning.

Shown below in T-account format are the changes affecting the retained
Shown below in T-account format are the changes affecting the retained earnings of Brenner-Jude Corporation during 2021. At January 1, 2021, the corporation had outstanding 105 million common shares, $1 par per share.
Required:
1. From the information provided by the account changes you should be able to re-create the transactions that affected Brenner-Jude’s retained earnings during 2021. Reconstruct the journal entries which can be used as spreadsheet entries in the preparation of a statement of cash flows. Also indicate any investing and financing activities you identify from this analysis that should be reported on the statement of cash flows.
2. Prepare a statement of retained earnings for Brenner-Jude for the year ended 2021.

The ink-jet printing division of Environmental Printing has grown tremendously in recent
The ink-jet printing division of Environmental Printing has grown tremendously in recent years. Assume the following transactions related to the ink-jet division occur during the year ended December 31, 2021.
Required:
Record any amounts as a result of each of these contingencies.
1. Environmental Printing is being sued for $11 million by Addamax. Plaintiff alleges that the defendants formed an unlawful joint venture and drove it out of business. The case is expected to go to trial later this year. The likelihood of payment is reasonably possible.
2. Environmental Printing is the plaintiff in an $9 million lawsuit filed against a competitor in the high-end color-printer market. Environmental Printing expects to win the case and be awarded between $6.5 and $9 million.
3. Environmental Printing recently became aware of a design flaw in one of its ink-jet printers. A product recall appears probable. Such an action would likely cost the company between $500,000 and $900,000.
