If the salary rate paid under the grant appointment is greater than the annual House Officer base salary (per Table 1, Paragraph 10), but less than the sum of House Officer base salary plus annual lump sum amount, then a further lump sum payment shall be made. The amount of the lump sum payment will be enough to match the total compensation that is paid to a full time House Officer, at the same House Officer level, who is not on a grant-funded appointment (base salary, plus "lump sum payment" per the salary schedule).
