By the end of this lesson you understand the structure of the income statement -- from revenue to the different levels of income -- and why it shows a period, not an instant.
\nThe income statement is one of the three financial statements, already covered in the previous module: the one that answers whether a company made or lost money during a specific period -- a quarter, a year. Unlike the balance sheet, which is a snapshot at an instant, the income statement is a movie: it shows what happened over the entire period, not a situation at a given moment.
\nIts structure follows a cascading logic: it starts from revenue -- everything billed through the company's activity -- and subtracts different categories of costs, arriving at a different level of income at each step. Operating income shows what the business earns or loses before accounting for how it's financed or taxes. Net income, at the end of the cascade, is what actually remains for shareholders, after all costs, interest, and taxes.
\nEach level of income answers a slightly different question. Operating income isolates the performance of the business itself, without the effect of how it's financed. Net income adds that financial and tax effect, and it's the figure everyone ultimately compares -- although it isn't always the most useful one for judging the quality of the underlying business.
\nThis lesson gives the general structure; the next one details what revenue is, the margins calculated between these levels, and the non-recurring items that sometimes distort the reading.
\nTwo companies can have the same operating income -- they earn the same from their activity -- and still show a very different net income if one of them has much more debt than the other: the interest on that debt reduces net income without the business itself having changed.
\nThe income statement shows whether a company made or lost money during a period, following a cascading structure from revenue down to net income, passing through operating income.
\nWhy is the income statement "a movie" and the balance sheet "a snapshot"?
\nWhy can two companies with the same operating income have very different net income?
