First, all future dates are built until the latest maturity date, using for that purpose the [Time series resampling recipe](recipe:compute_extrapolate_dates) from the Time Series Preparation plugin. It is joined with the selected snapshot of the portfolio in the [join recipe](recipe:compute_extrapolate_dates_portfolios). Finally, in the next two recipes, the balances are estimated assuming that capital repayment are done uniformally until maturity.
