Publicly owned companies must report earnings per share (EPS) below the net income line in their income statements. This is mandated by generally accepted accounting practices (GAAP). The EPS gives investors a means of determining the amount the business earned on its stock share investments. In other words, EPS tells investors how much net income the business earned for each stock share they own. It’s calculated by dividing net income by the total number of capital stock share. It’s important to the stockholders who want the net income of the business to be communicated to them on a per share basis so they can compare it with the market price of their shares.

Private businesses don’t have to report EPS because stockholders focus more on the business’s total net income.

Publicly-held companies actually report two EPS figures, unless they have what’s known as a simple capital structure. Most publicly-held companies though, have complex capital structures and have to report two EPS figures. One is called the basic EPS; the other is called the diluted EPS. Basic EPS is based on the number of stock shares that are outstanding. Diluted earnings are based on shares that are outstanding and shares that may be issued in the future in the form of stock options.

Obviously this is a complicated process. An accountant has to adjust the EPS formula for any number of occurrences or changes in the business. A business might issue additional stock shares during the year and buy back some of its own shares. Or it might issue several classes of stock, which will cause net income to be divided into two or more pools – one pool for each class of stock. A merger, acquisition or divestiture will also impact the formula for EPS.

Depreciation is a term we hear about frequently, but don’t really understand. It’s an essential component of accounting however. Depreciation is an expense that’s recorded at the same time and in the same period as other accounts. Long-term operating assets that are not held for sale in the course of business are called fixed assets. Fixed assets include buildings, machinery, office equipment, vehicles, computers and other equipment. It can also include items such as shelves and cabinets. Depreciation refers to spreading out the cost of a fixed asset over the years of its useful life to a business, instead of charging the entire cost to expense in the year the asset was purchased. That way, each year that the equipment or asset is used bears a share of the total cost. As an example, cars and trucks are typically depreciated over five years. The idea is to charge a fraction of the total cost to depreciation expense during each of the five years, rather than just the first year.

Depreciation applies only to fixed assets that you actually buy, not those you rent or lease. Depreciation is a real expense, but not necessarily a cash outlay expense in the year it’s recorded. The cash outlay does actually occur when the fixed asset is acquired, but is recorded over a period of time.

Depreciation is different from other expenses. It is deducted from sales revenue to determine profit, but the depreciation expense recorded in a reporting period doesn’t require any true cash outlay during that period. Depreciation expense is that portion of the total cost of a business’s fixed assets that is allocated to the period to record the cost of using the assets during period. The higher the total cost of a business’s fixed assets, then the higher its depreciation expense.
