Convertible Senior Note

A debt security issued by a company that takes priority over other debt and can be converted into a predefined amount of equity.

A convertible senior note is a hybrid debt security issued by corporations to raise capital. It is classified as "senior" because, in the event of bankruptcy or liquidation, holders of these notes have priority claim over common stockholders and junior debt holders. The "convertible" feature allows investors to convert the debt into a specified number of shares of the issuing company's common stock under predetermined conditions. For investors, these notes offer a safer way to invest in high-growth or volatile companies. They provide regular interest payments (coupons) and principal protection like a traditional bond, while offering upside potential through equity conversion if the stock price rises significantly. For the issuing company, convertible senior notes typically carry a lower interest rate than traditional bonds because the conversion option acts as a sweetener for investors. However, if the notes are converted, they dilute existing shareholders by increasing the outstanding share count.

A company issues a convertible senior note with a face value of $1,000, a coupon rate of 2%, and a conversion price of $50 per share. The conversion ratio is calculated as $1,000 / $50 = 20 shares. If the company's stock price rises to $70, the noteholder can convert their $1,000 note into 20 shares of stock, which are now worth 20 $70 = $1,400, capturing a 40% gain on their principal.
