The preliminary holdings of the fund are those taken prior to the start of each business day and are used to generate a daily static cash flow profile. This is determined by using a number of consistent assumptions which BlackRock believe to be appropriate in illustrating the cash flow profile of the fund for that day. The cash flow data is projected using the aggregated expected coupon and maturities of the individual bond holdings of the fund. Holdings and cashflows are subject to change and this information is not to be relied upon.
