What it means
When a company issues convertible bonds or preferred shares, it includes a conversion ratio to spell out the rules for swapping that investment into ordinary shares. For non-finance managers, understanding this metric is vital because it directly impacts company dilution.
When investors convert their debt into shares, the total number of shares increases, which can reduce existing owners' percentage stake in the business. This ratio is fixed at the start, though companies sometimes include adjustment clauses for events like stock splits.
A higher ratio means you get more shares per bond, making the conversion feature more attractive to investors if the share price rises. It acts as a bridge between fixed income and equity financing, offering lenders a sweetener in exchange for a lower interest rate on their loan.
Businesses use convertible securities to raise capital at a cheaper rate upfront, betting that the business will grow and make the equity option valuable. Managers must monitor these ratios carefully when planning capital structures.
If the share price skyrockets, many investors will convert, changing the ownership landscape and capital base of the organisation overnight.
In practice
Real-world examples.
Example
TechStart issued a bond with a conversion ratio of 20. This means every one thousand pound bond can be swapped for 20 ordinary shares in the company once the target share price is reached.
Example
BrightRetail issued preferred shares with a conversion ratio of 5. An investor holding 1,000 preferred shares can trade them in for 5,000 ordinary shares during the designated conversion window.
Example
GreenEnergy Corp set a conversion ratio of 50 for its convertible debentures. For each 500 pound note held, the investor has the right to claim 50 ordinary shares as the business expands.
Think of it
“Think of a conversion ratio like a fixed exchange rate at an airport kiosk, but instead of trading pounds for euros, you are trading a loan voucher for slices of company ownership.
Formula
Calculation
Conversion Ratio = Par Value of Bond / Conversion Price
For example, if a corporate bond has a par value of 1,000 pounds and the agreed conversion price is 50 pounds per share, the calculation is 1,000 divided by 50. This gives a conversion ratio of 20 shares per bond.Case study
Seen in the real world.
Oakwood Manufacturing needed capital to build a new factory but wanted to avoid high interest payments. To attract lenders, Oakwood issued 2 million pounds in convertible bonds carrying a 4 percent interest rate and a conversion ratio of 40 shares per 1,000 pound bond. Over the next three years, Oakwood launched a successful product line, and its share price jumped from 20 pounds to 35 pounds.
Sensing a great return, investors holding all 2 million pounds worth of bonds decided to convert their debt into equity. Using the conversion ratio of 40, Oakwood issued 80,000 new ordinary shares to these bondholders. The company successfully wiped 2 million pounds of debt from its balance sheet, saving on future interest payments. However, the existing founders noticed their ownership percentages diluted as those 80,000 new shares entered the market.
Watch out
Common mistakes.
- Confusing the conversion ratio with the conversion price, which are two different figures.
- Ignoring the dilution effect on existing shareholders when calculating future earnings per share.
- Assuming the ratio changes automatically with market price fluctuations when it is usually fixed.
Questions
People also ask.
Can a company change the conversion ratio after issuing the bond?
Usually no, the ratio is fixed at issuance to protect the investor, though anti-dilution clauses can adjust it during stock splits.
Is a higher conversion ratio always better for the investor?
Yes, a higher ratio means you get more shares for your investment, which is more profitable if the share price rises.
How does conversion affect the company's debt?
When investors convert their bonds into shares, the company's liability decreases because the debt is wiped out and replaced with equity.
