What is a 'Flotation Cost'
Flotation costs are incurred by a publicly traded company when it issues new securities, and includes expenses such as underwriting fees, legal fees and registration fees. Companies must consider the impact these fees will have on how much capital they can raise from a new issue. Flotation costs, expected return on equity, dividend payments and the percentage of earnings the business expects to retain are all part of the equation to calculate a company's cost of new equity.
BREAKING DOWN 'Flotation Cost'
Companies raise capital in two ways: debt via bonds and loans, or equity. Some companies prefer issuing bonds or obtaining a loan, especially when interest rates are low, and especially because the interest paid on many debts is taxdeductible, while equity returns are not. Other companies prefer equity because it does not need to be paid back; however, selling equity also entails giving up an ownership stake in the company. There are also flotation costs associated with issuing new equity, or newly issued common stock. These include costs such as investment banking and legal fees, accounting and audit fees, and fees paid to a stock exchange to list their shares. The difference between the cost of existing equity and the cost of new equity is the flotation cost. The flotation cost is expressed as a percentage of the issue price and is incorporated into the price of new shares as a reduction. A company will often use a weighted cost of capital (WACC) calculation to determine what share of its funding should be raised from new equity and what portion from debt.
Calculating the Cost of Float in New Equity
The equation for calculating the flotation cost of new equity using the dividend growth rate is:
(Dividend / (Price * (1Flotation Cost) ) + Growth Rate
where: the Dividend = the dividend in the next period;
Price = the issue price of one share of stock
Flotation Cost = the ratio of flotation cost to the price
Growth Rate = the dividend growth rate.
As an example, assume Company A needs capital and decides to raise $100 million in common stock at $10 per share to meet its capital requirements. Investment bankers receive 7% of the funds raised. Company A pays out $1 in dividends per share next year and is expected to increase dividends by 10% the following year.
Using these variables, the cost of new equity is calculated with the following equation: ($1 / ($10 * (17%)) + 10%. The answer is 20.7%.
If the analyst assumes no flotation cost, the answer is the cost of existing equity.
The cost of existing equity is calculated with the following formula: ($1 / ($10 * (10%)) + 10%. The answer is 20.0%.
The difference between the cost of new equity and the cost of existing equity is the flotation cost, which is (20.720.0%) = 0.7%. In other words, the flotation costs increased the cost of the new equity issuance by 0.7%.
