ISEQ® Bond Indices (Total Return) Overview.
Like the ISEQ® Price BIS, the ISEQ® Return BIS is comprised of ISEQ® All Bond Index (Return), ISEQ® Under 3 Bond Index (Return), ISEQ® Under 5 Bond Index (Return), ISEQ® Under 10 Bond Index (Return), ISEQ® 5 Plus Bond Index (Return), ISEQ® 10 Plus Bond Index (Return). The components of the ISEQ® Return BIS and the rules for inclusion are the same as for the ISEQ® Price BIS.
The difference between the ISEQ® Price BIS and ISEQ® Return BIS is that the ISEQ® Price BIS uses the clean prices while the ISEQ® Return BIS uses the dirty prices in the calculation of the indices. The dirty price is the clean price plus accrued interest. In this way investors can see the "total" return from the market.
The ISEQ® Return BIS has the same base dates, values and Historical performance as the ISEQ® Price BIS.
