EX-99.D 6 gmoaddendum.txt ADDENDUM TO GMO IA AGREEMENT VANGUARD VARIABLE INSURANCE FUND INVESTMENT ADVISORY AGREEMENT ADDENDUM Effective April 30, 2003 This Addendum amends Section 4 of the Investment Advisory Agreement dated September 29, 2000 between Vanguard VARIABLE INSURANCE FUND - SMALL COMPANY GROWTH PORTFOLIO (the "Fund") and GRANTHAM, MAYO, VAN OTTERLOO & CO. LLC ("GMO") as follows. 4. COMPENSATION OF GMO. For the services to be rendered by GMO as provided in this Agreement, the Fund will pay to GMO at the end of each of the Fund's fiscal quarters, a Basic Fee calculated by applying a quarterly rate, based on the annual percentage rate of 0.225%, to the average month-end net assets of the GMO Portfolio for the quarter. The Basic Fee, as provided above, will be increased or decreased by applying a Performance Fee Adjustment (the "Adjustment"). The Adjustment will be calculated as a percentage of the average net assets of the GMO Portfolio for the 36-month period ending with the then-ended quarter, and the Adjustment will change proportionately with the investment performance of the GMO Portfolio relative to the investment performance of the Russell 2500 Growth Index for the same period. The Adjustment applies as follows: CUMULATIVE 36-MONTH PERFORMANCE OF THE ADJUSTMENT AS A PERCENTAGE OF GMO PORTFOLIO VS. INDEX AVERAGE NET ASSETS(A) ----------------------- --------------------- Trails index -0.15% Exceeds Index by 0% baseline to 3% Linear increase from -0.15% to 0% Exceeds Index by 3% baseline to 6% Linear increase from 0% to +0.15% Exceeds Index by more than 6% +0.15% ------------------ (a) For purposes of this calculation, the average net assets will be calculated as average month-end net assets over the same time period for which performance is measured. Linear application of the Adjustment provides for an infinite number of results within the stated range. Example: If the cumulative 36-month performance of the GMO Portfolio versus the Index is +3.6%, and Adjustment of +0.03%* or [(0.6% divided by 3%)0.15%] would apply. This would be calculated as [(a divided by b)0.15%], where a equals the percentage amount by which the performance of the GMO Portfolio has exceeded the applicable baseline percentage for the linear adjustment, and b equals the size of the range over which the linear adjustment applies. ----------------------------- *As rounded for purposes of this example. In practice, the calculation will be extended to the eighth decimal point. 4.1. TRANSITION RULE FOR CALCULATING GMO'S COMPENSATION. The fee structure described in Section 4 will not be fully operable until the quarter ending June 30, 2006.
