##### Coverage Bond

Bond is a child type of Tradable that represents a financial contract that pays its holder a stream of cash flows - called coupons - in regular time intervals plus a possible final payment - called redemption - at maturity.
The coupons may be fixed or floating.
In the latter case, the coupon amount depends on the value that some predefined index assumes at either the beginning or the end of the respective accrual period.
If there is only one date in the defined
Key Bond::Accrual Schedule, then it represents a zero bond.
Look up the information in the above link for details on how to set up such a date schedule.

CashFlows
All cash flows displayed in chronological order as a table with a maximum of 18 columns.
The column titles indicate the meaning of the respective data.
In particular:
The column titled #Notional shows the notional that is relevant for determining the respective cash flow, which is the notional at the beginning of the accrual period.
In the special case of fx reset, this will be the converted domestic notional that arises after the fixed foreign notional is multiplied with the spot fx rate observed at the beginning of the accrual period.
The column titled #AdjIndex shows the adjusted index fixing, which equals the sum of the forecasted (forward) index plus a potential convexity adjustment that arises if the index is either non-ibor or sets in arrears.
The column titled #Rate shows the final rate that leads to the accrued amount after it is multiplied with the accrual period.
The column titled #Leg contains the index of the leg that contains the respective cash flow, where 1 stands for the first leg.
The column titled #InLegCF contains the index of the respective cash flow within the containing leg, where 1 stands for the first cash flow in that leg.
