Interest shall be credited to the Cash Account balance (including both principal and interest) of each participating Director based on the balance at the end of each calendar quarter. The rate of interest to be applied at the end of each calendar quarter is set forth below in this Paragraph 4. The interest credit shall continue to be applied to the Cash Account of a Director, even if ceasing to serve as a Director, until all amounts credited to his or her Cash Account have been paid. Said interest shall be calculated quarterly, based upon the average daily balance of the Director’s Cash Account since the preceding calendar quarter, after giving effect to any reduction in the Cash Account as a result of any payments. The remaining annual payments will be recomputed to reflect the additional interest credits.
