The term “stated redemption price at maturity” means the amount fixed by the last modification of the purchase agreement and includes interest and other amounts payable at that time (other than any interest based on a fixed rate, and payable unconditionally at fixed periodic intervals of 1 year or less during the entire term of the debt instrument).
In the case of any issue of debt instruments not issued for property and not publicly offered, the issue price of each such instrument is the price paid by the first buyer of such debt instrument.
The terms “initial offering price” and “price paid by the first buyer” include the aggregate payments made by the purchaser under the purchase agreement, including modifications thereof.
