(a) Treasury will establish the Federal Terrorism Policy Surcharge based on the following factors and considerations:

1. (1) In the case of a mandatory recoupment amount, the requirement to collect 133 percent of that amount;
2. (2) The total dollar amount to be recouped as a percentage of the latest available annual aggregate industry direct written premium information;
3. (3) The adjustment factors for terrorism loss risk-spreading premiums described in section 103(e)(8)(D) of the Act;
4. (4) The annual 3 percent limitation on terrorism loss risk-spreading premiums collected on a discretionary basis as provided in section 103(e)(8)(C) of the Act;
5. (5) A preferred minimum initial assessment period of one full year and subsequent extension periods in full year increments;
6. (6) The collection timing requirements of section 103(e)(7)(E) of the Act;
7. (7) The likelihood that the amount of the Federal Terrorism Policy Surcharge may result in the collection of an aggregate recoupment amount in excess of the planned recoupment amount; and
8. (8) Such other factors as the Secretary considers important.
