Inventory is usually the largest current asset of a business that sells products. If the inventory account is greater at the end of the period than at the start of the reporting period, the amount the business actually paid in cash for that inventory is more than what the business recorded as its cost of good sold expense. When that occurs, the accountant deducts the inventory increase from net income for determining cash flow from profit.

the prepaid expenses asset account works in much the same way as the change in inventory and accounts receivable accounts. However, changes in prepaid expenses are usually much smaller than changes in those other two asset accounts.

The beginning balance of prepaid expenses is charged to expense in the current year, but the cash was actually paid out last year. this period, the business pays cash for next period’s prepaid expenses, which affects this period’s cash flow, but doesn’t affect net income until the next period. Simple, right?

As a business grows, it needs to increase its prepaid expenses for such things as fire insurance premiums, which have to be paid in advance of the insurance coverage, and its stocks of office supplies. Increases in accounts receivable, inventory and prepaid expenses are the cash flow price a business has to pay for growth. Rarely do you find a business that can increase its sales revenue without increasing these assets.

The lagging behind effect of cash flow is the price of business growth. Managers and investors need to understand that increasing sales without increasing accounts receivable isn’t a realistic scenario for growth. In the real business world, you generally can’t enjoy growth in revenue without incurring additional expenses.

Investors calculate the acid test ratio, also known as the quick ratio or the pounce ratio. This ratio excludes inventory and prepaid expenses, which the current ratio includes, and it limits assets to cash and items that the business can quickly convert to cash. This limited category of assets is known as quick or liquid assets. The acid-text ratio is calculated by dividing the liquid assets by the total current liabilities.

This ratio is also known as the pounce ratio to emphasize that you’re calculating for a worst-case scenario, where the business’s creditors could pounce on the business and demand quick payment of the business’s liabilities. Short term creditors do not have the right to demand immediate payment, except in unusual circumstances. This ratio is a conservative way to look at a business’s capability to pay its short-term liabilities.

One factor that affects the bottom-line profitability of a business is whether it uses debt to its advantage. A business may realize a financial leverage gain, meaning it earns more profit on the money it has borrowed than the interest paid for the use of the borrowed money. A good part of a business’s net income for the year may be due to financial leverage. The ROA ratio is determined by dividing the earnings before interest and income tax (EBIT) by the net operating assets.

An investor compares the ROA with the interest rate at which the corporation borrowed money. If a business’s ROA is 14 percent and the interest rate on its debt is 8 percent, the business’s net gain on its capital is 6 percent more than what it’s paying in interest.

ROA is a useful ratio for interpreting profit performance, aside from determining financial gain or loss. ROA is called a capital utilization test that measures how profit before interest and income tax was earned on the total capital employed by the business.

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.
