 than such amount. If your debt security has de minimisoriginal issue discount, you must include the de minimisamount in income as stated principal payments are made on the debt security, unless you make the election described below under “— Election to Treat All Interest as Original Issue Discount.” You can determine the includible amount with respect to each such payment by multiplying the total amount of your debt security’s de minimisoriginal issue discount by a fraction equal to:

| · |     | the amount of the principal payment made, divided by: |

| · |     | the stated principal amount of the debt security. |

Generally, if your discount debt security matures more than one year from its date of issue, you must include original issue discount, or OID, in income before you receive cash attributable to that income. The amount of OID that you must include in income is calculated using a constant-yield method, and generally you will include increasingly greater amounts of OID in income over the life of your debt security. More specifically, you can calculate the amount of OID that you must include in income by adding together the daily portions of OID with respect to your discount debt security for each day during the taxable year or portion of the taxable year that you hold your discount debt security. You can determine the daily portion by allocating to each day in any accrual period a pro rataportion of the OID allocable to that accrual period. You may select an accrual period of any length with respect to your discount debt security and you may vary the length of each accrual period over the term of your discount debt security. However, no accrual period may be longer than one year and each scheduled payment of interest or principal on the discount debt security must occur on either the first or final day of an accrual period. You can determine the amount of OID allocable to an accrual period by:

| · |     | multiplying your discount debt security’s adjusted issue price at the beginning of the accrual period by your debt security’s yield to maturity; and 
 then                                                                                                                                                 |

-103-

| · |     | subtracting from this figure the sum of the payments of qualified stated interest on your debt security allocable to the accrual period. |

You must determine the discount debt security’s yield to maturity on the basis of compounding at the close of each accrual period and adjusting for the length of each accrual period. Further, you determine your discount debt security’s adjusted issue price at the beginning of any accrual period by:
