The Income Estimator is a tool provided to help you anticipate the potential dividends, capital gains, principal and interest income you may expect to receive based on your current account holdings. For dividends, the column entitled "Upcoming Payments" reflects either an "Estimated" amount, which is based solely on the last payment made by the issuer, or an "Announced" amount, which reflects the actual amount announced by the issuer. For capital gains, only those amounts that have been announced by the issuer will be provided. Interest payments and return of principal are calculated based on simple arithmetic formulae derived from the rates and payment schedules set by the issuer and assume the issuer is not in default. As with any investment, there is no guarantee you will receive these payments. Past performance is not an indication of future results.
So from what I can tell its based on the divy from last year but it also says or an ANNOUNCED amount. This is all the info they could give me so take it for what it is GLTA in it for the long haul
