On January 1, 2001, United Corporation issued $10 million (10,000 units of $1,000 bond) of 8% convertible bonds at 105. The bonds mature in 20 years. Each $1,000 convertible bond can be converted to 20 shares of common stock at the bondholder's option.

On January 1, 2001, the market value of each warrant was $6. On January 1, 2007, 20% of the warrants were exercised and 40% of convertible bonds were converted to stocks.
