My accounting firm's biggest client, which pays my firm many millions of dollars each year, has presented the following information in its income statement:

Revenues 10,000,000,000

Cost of goods sold 7,000,000,000

Gross profit 3,000,000,000

SG&A 2,500,000,000

Pre-tax profit 500,000,000

Extraordinary (loss) (1,700,000,000)

(Loss) before taxes (1,200,000,000)

The income statement then goes on and gives the provision for income taxes and the net income.

The notes to the financial statements explain the extraordinary item. "Management has evaluated the carrying value of accounts receivable and has determined that it should be written down by $200,000,000. The research and development project by which the company was attempting to improve the standard widget never produced any results, so management has decided to write off the entire $500,000,000 balance of deferred R&D which had previously appeared as an asset on the balance sheet, together with $100,000,000 of this year's expenditures. Inventory in the amount of $400,000,000 was declared to be obsolete. These amounts total $1,200,000,000 of the extraordinary loss. The remainder of the extraordinary loss consists of the forgiveness of loans to company executives and members of the company's board of directors."

Assume that I can tie out every amount in every general ledger account and that I have found sufficient competent evidential matter to make you believe that the account balances are correct. Those account balances carry forward to the financial statements.

I want to know what is the proper audit opinion to render?
