## Detailed Description

Forward contract on a fixed-rate bond

1. valueDate refers to the settlement date of the bond forward contract. maturityDate is the delivery (or repurchase) date for the underlying bond (not the bond's maturity date).

2. Relevant formulas used in the calculations ( refers to a price):

a. where refers to the accrued interest on the underlying bond.

b.

c. where represents the ith bond cash flow (coupon payment) associated with the underlying bond falling between the settlementDate and the deliveryDate. (Note the two different discount curves used in b. and c.)

Example: valuation of a repo on a fixed-rate bond

Possible enhancements:
  Add preconditions and tests

Possible enhancements:
  Create switch- if coupon goes to seller is toggled on, don't consider income in the calculation.

Possible enhancements:
  Verify this works when the underlying is paper (in which case ignore all AI.)

Warning:
  This class still needs to be rigorously tested

Examples:
  Repo.cpp.

## Constructor & Destructor Documentation

FixedRateBondForward | ( | const Date & | valueDate,
|  | const Date & | maturityDate,
|  | Position::Type | type,
|  | Real | strike,
|  | Natural | settlementDays,
|  | const DayCounter & | dayCounter,
|  | const Calendar & | calendar,
|  | BusinessDayConvention | businessDayConvention,
|  | const boost::shared_ptr< FixedRateBond > & | fixedCouponBond,
|  | const Handle< YieldTermStructure > & | discountCurve = `Handle< YieldTermStructure >()`,
|  | const Handle< YieldTermStructure > & | incomeDiscountCurve = `Handle< YieldTermStructure >()`
| ) |  |

If strike is given in the constructor, can calculate the NPV of the contract via NPV().

If strike/forward price is desired, it can be obtained via forwardPrice(). In this case, the strike variable in the constructor is irrelevant and will be ignored.

## Member Function Documentation

Real spotIncome | ( | const Handle< YieldTermStructure > & | incomeDiscountCurve | ) | const`[virtual]`

NPV of bond coupons discounted using incomeDiscountCurve.

Here only coupons between max(evaluation date,settlement date) and maturity date of bond forward contract are considered income.

Implements Forward.

void performCalculations | ( |  | ) | const`[protected, virtual]`

In case a pricing engine is not used, this method must be overridden to perform the actual calculations and set any needed results. In case a pricing engine is used, the default implementation can be used.

Reimplemented from Forward.
