Let us understand the concept of accounting for convertible preferred stock through an example.

An investor bought 100 shares of convertible preferred stock in ABC Company @ 500 per share on June 1, 2007. So, the initial investment made by an investor is $50000 (100 shares * $500). It offers a fixed dividend yieldDividend YieldDividend yield ratio is the ratio of a company's current dividend to its current share price.  It represents the potential return on investment for a given stock.read more of 5%, i.e. $25 per share along with a special conversion right wherein 1 share of preferred stock can be converted into 50 shares of common stock (known as conversion ratio), i.e., if an investor opts for conversion, he will be entitled to 5000 common shares (100 preferred stock * 50 common shares). This right can only be applied after June 1, 2008 (the conversion date).

Applying the below formulae can give the total cost per common share after conversion is applied:

Par Value of Convertible Preferred Stock/No. of Common Stock Entitled as a Part of the Conversion.

In this case, it’s $10 (500/50) which is termed as the conversion price.

Case #1

Now let’s assume on June 1, 2008, the stock price was trading at @7 per share in the market. If the investor decides to convert his holding into common stock, the total value of his investment will be $35000 (5000 common shares * $7) on that day. It will fetch him a total loss of $15000 after considering his initial investment of $50000.

Case #2

Now let’s assume that the stock price increased to $30. He would exercise his conversion right as he can get the same stock at ten compared to the market price of $30. The difference between $30 and $10 is called the conversion premium. Post conversion, the total value of his investment will increase to $150000 from $50000, giving him a net realizable gain of $100000.

  • Convertible preferred stock bear higher risks in the event of default as they will be paid only after repayment of principal and interest to bondholders, i.e., they will be par to other equity shareholders.
  • When the conversion feature is exercised, the preference shareholder will be treated as another equity shareholder who enjoys no priority in either dividend or asset distribution.
  • The exercise and valuation of convertible preferred stock ofrconvertible options increases the number of outstanding shares and creates dilution of control from the perspective of equity shareholders. Therefore, each shareholder is entitled to a smaller proportion of firm assets and profits. This problem never arises with traded options. If an investor buys an exchange-traded option and subsequently exercises it, there is no effect on the number of shares outstanding.

Thus, it is necessary to have a clear idea about the pros and cons of these type of irredeemable or redeemable convertible preferred stock to that investors can take informed decisions and invest their money in financial securities that best suits their own risk appetite and return expectations.

  • Another key difference is that the former has the option to convert their preference holdings to common stock as per ther own discretion of as per the policy of the company. This does not apply for the latter because they already exist in the form of common stock.
  • The former typically does not get any right to vote or has very limited right to do so, in relation to corporate matters like management decisions, election of directors, etc. The latter has a right to vote on all important matters relate to the company.
  • Even in case of liquidation, or bankruptcy of the business, the former has the preferencial right to claim their part from the liquidated assets of the business, whereas the latter can get their claims only after the former has been paid completely.
  • The risk in case of the former is lesser than the latter because the former gets a fixed payment as return, which is not applicable in case of the latter.
