Parts of an Income Statement, Part 3

 While some lines of an income statement depend on estimates or forecasts, the interest expense line is a basic equation. When accounting for income tax expense, however, a business can use different accounting methods for some of its expenses than it uses for calculating its taxable income. The hypothetical amount of taxable income, if the accounting methods used were used in the tax return is calculated. Then the income tax based on this hypothetical taxable income is fitured. This is the income tax expense reported in the income statement. This amount is reconciled with the actual amount of income tax owed based on the accounting methods used for income tax purposes. A reconciliation of the two different income tax amounts is then provided in a footnote on the income statement.

Net income is like earnings before interest and tax (EBIT) and can vary considerably depending on which accounting methods are used to report sales revenue and expenses. This is where profit smoothing can come into play to manipulate earnings. Profit smoothing crosses the line from choosing acceptable accounting methods from the list of GAAP and implementing these methods in a reasonable manner, into the gray area of earnings management that involves accounting manipulation.

It's incumbent on managers and business owners to be involved in the decisions about which accounting methods are used to measure profit and how those methods are actually implemented. A manager can be requires to answer questions about the company's financial reports on many occasions. It's therefore critical that any officer or manager in a company be thoroughly familiar with how the company's financial statements are prepared. Accounting methods and how they're implemented vary from business to business. A company's methods can fall anywhere on a continuum that's either left or right of center of GAAP.

It's obvious financial statement have a lot of numbers in them and at first glance it can seem unwieldy to read and understand. One way to interpret a financial report is to compute ratios, which means, divide a particular number in the financial report by another. Financial statement ratios are also useful because they enable the reader to compare a business's current performance with its past performance or with another business's performance, regardless of whether sales revenue or net income was bigger or smaller for the other years or the other business. In order words, using ratios can cancel out difference in company sizes.

There aren't many ratios in financial reports. Publicly owned businesses are required to report just one ratio (earnings per share, or EPS) and privately-owned businesses generally don't report any ratios. Generally accepted accounting principles (GAAP) don't require that any ratios be reported, except EPS for publicly owned companies. 

Ratios don't provide definitive answers, however. They're useful indicators, but aren't the only factor in gauging the profitability and effectiveness of a company. 

One ratio that's a useful indicator of a company's profitability is the gross margin ratio. This is the gross margin divided by the sales revenue. Businesses don't discose margin information in their external financial reports. This information is considered to be proprietary in nature and is kept confidential to shield it from competitors.

The profit ratio is very important in analyzing the bottom-line of a company. It indicates how much net income was earned on each $100 of sales revenue. A profit ratio of 5 to 10 percent is common in most industries, although some highly price-competitive industries, such as retailers or grocery stores will show profit ratios of only 1 to 2 percent.
