The amount of revenue obligation securities issued to refund |
securities previously issued may not be taken into account in |
determining the principal amount of securities outstanding, |
provided that proceeds of the refunding securities are applied as |
promptly as possible to the refunding of the previously issued |
securities. In computing the total amount of revenue obligation |
securities of the authority that may at any time be outstanding |
for any purpose, the amounts of the outstanding revenue |
obligation securities that have been issued as capital |
appreciation bonds or as similar instruments are valued as of any |
date of calculation at their then current accreted value rather |
than their face value. |
