Island Capital has the following capitl structure:

Bonds... $20, 000, 000

Perpetuals (preferred shares)... 4, 000, 000

Common shares... 20, 000, 000

Retained earnings... 19,500,000

$63, 500,000

The existing bonds have a coupon rate of 8 percent with 18 years left to maturity, but current yields on these bonds are 11 percent. Flotation costs of $25.00 per $1,000 bond would be expected on a new issue.

The existing perpetuals have a $25.00 par vlaue and an annual dividend rate of 9 percent. New perpetuals could be issued at a $50.00 par value with 8 percent yield. Floatation costs would be 3 percent.

There are four million common shares outstanding that currently trade at $18.00 per share and expect to pay a dividend next year of $175 that will continue to grow at 7 percent per annum for the foreseeable future. New shares could be issued at $17.50 and would require flotation expenses of 5 percent of proceeds.

Island's tax rate is 39 percent, and it is expected that internally generated funds will be sufficient to fund capital projects in the near future.
