MGM International operates casinos and resorts across the U.S. and in China. The company reported the following in its SEC filings.
We maintain an allowance for doubtful casino accounts at all of our operating casino resorts. The provision for doubtful accounts, an operating expense, increases the allowance for doubtful accounts. We regularly evaluate the allowance for doubtful casino accounts. At domestic resorts where marker play is not signify- cant, the allowance is generally established by applying standard reserve percentages to aged account balances. At domestic resorts where marker play is significant, we apply standard reserve percentages to aged account balances under a specified dollar amount and specifically analyze the collectability of each account with a balance over the specified dollar amount, based on the age of the account, the customer’s financial condition, collection history and any other known information. MGM China specifically analyzes the collectability of casino receivables on an individual basis taking into account the age of the account, the financial condition and the collection history of the gaming promoter or casino customer.

Accounts receivable, net	$612,717	$657,206	$540,545	$542,924

a). Analyze the allowance account for each of the four years by computing the ratio of the allowance to gross accounts receivable.
Note: Round the percentage to two decimal places (for example, enter 14.56% for 14.55555%).

	2016	2017	2018	2019
Allowance / Accounts receivable, gross	15.28%	14.62%	12.14%	13.37%

b). Reformulate the income statement and balance sheet accounts listed below for all four years to reflect the four‑year average of the allowance to gross accounts receivable. Assume that the tax rate is 22% for all four years. Follow the process in Analyst Adjustments 5.2; income statement first, followed by balance sheet.
Note: Do not round until your final answers; round your final answers to the nearest whole dollar.

c). Ignoring the analysis in part b, assume that we anticipate that the coronavirus pandemic of 2020 will shrink gambling activities worldwide. This will impair existing (2019) accounts receivable. For each of the 2019 balance sheet and income statement accounts listed below indicate what adjustments would be required under the assumption that the allowance to gross receivables ratio will increase to 25% of total gross receivables.
Note: Do not round until your final answers; round your final answers to the nearest whole dollar.
