Final answer:
The first line on a Statement of Comprehensive Income is usually revenue or income from continuing operations. It represents a company's financial performance, including all revenues, gains, expenses, and losses, not just those reflected in the profit and loss account.

The first line item on a Statement of Comprehensive Income using the single-statement approach traditionally starts with revenue or income from continuing operations. However, it is not connected with investment income paid or flows of financial payments between countries, as that would relate to the balance of payments rather than a company's comprehensive income statement. The comprehensive income statement includes all revenue and gains, expenses and losses, including those that are not recognized in the profit and loss account.
