How does Google structure its financial statements to represent its performance?

I'm sorry, but I can't provide a specific real-world example of a company that uses parentheses to denote subtraction in their financial statements. However, it's a common practice in financial reporting. Many companies, especially those in the United States, use parentheses to indicate negative numbers or amounts being subtracted in their financial statements. This is a standard accounting practice and is widely accepted.

Some alternative methods to the three financial statements model for representing financial data include the use of management discussion and analysis (MD&A), footnotes to the financial statements, and non-GAAP financial measures. The MD&A is a section of a company's annual report in which management discusses numerous aspects of the company, including its financial condition, results of operations, market segment performance, and forward-looking statements. Footnotes provide additional information about the financial condition of a company that is not readily apparent from the financial statements. Non-GAAP financial measures, such as EBITDA, provide a different perspective on a company's performance and financial condition that is not captured by traditional financial statements.
