Detailed Description

Base bond class.

Derived classes must fill the uninitialized data members.

Warning

Most methods assume that the cash flows are stored sorted by date, the redemption(s) being after any cash flow at the same date. In particular, if there's one single redemption, it must be the last cash flow,

Tests

*
price/yield calculations are cross-checked for consistency.
*
price/yield calculations are checked against known good values.

Constructor & Destructor Documentation

Bond (Natural settlementDays, const Calendar & calendar, const Date & issueDate = Date(), const Leg & coupons = Leg())

constructor for amortizing or non-amortizing bonds.

Redemptions and maturity are calculated from the coupon data, if available. Therefore, redemptions must not be included in the passed cash flows.

Bond (Natural settlementDays, const Calendar & calendar, Real faceAmount, const Date & maturityDate, const Date & issueDate = Date(), const Leg & cashflows = Leg())

old constructor for non amortizing bonds.

Warning

The last passed cash flow must be the bond redemption. No other cash flow can have a date later than the redemption date.

Member Function Documentation

const Leg & cashflows () const

Note:

returns all the cashflows, including the redemptions.

const Leg & redemptions () const

returns just the redemption flows (not interest payments)

const boost::shared_ptr<CashFlow>& redemption () const

returns the redemption, if only one is defined

Real cleanPrice () const

theoretical clean price

The default bond settlement is used for calculation.

Warning

the theoretical price calculated from a flat term structure might differ slightly from the price calculated from the corresponding yield by means of the other overload of this function. If the price from a constant yield is desired, it is advisable to use such other overload.

Real dirtyPrice () const

theoretical dirty price

The default bond settlement is used for calculation.

Warning

the theoretical price calculated from a flat term structure might differ slightly from the price calculated from the corresponding yield by means of the other overload of this function. If the price from a constant yield is desired, it is advisable to use such other overload.

Real settlementValue () const

theoretical settlement value

The default bond settlement date is used for calculation.

Rate yield (const DayCounter & dc, Compounding comp, Frequency freq, Real accuracy = 1.0e-8, Size maxEvaluations = 100) const

theoretical bond yield

The default bond settlement and theoretical price are used for calculation.

Real cleanPrice (Rate yield, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date()) const

clean price given a yield and settlement date

The default bond settlement is used if no date is given.

Real dirtyPrice (Rate yield, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date()) const

dirty price given a yield and settlement date

The default bond settlement is used if no date is given.

Real settlementValue (Real cleanPrice) const

settlement value as a function of the clean price

The default bond settlement date is used for calculation.

Rate yield (Real cleanPrice, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date(), Real accuracy = 1.0e-8, Size maxEvaluations = 100) const

yield given a (clean) price and settlement date

The default bond settlement is used if no date is given.

Real cleanPriceFromZSpread (Spread zSpread, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date()) const

clean price given Z-spread

Z-spread compounding, frequency, daycount are taken into account The default bond settlement is used if no date is given. For details on Z-spread refer to: 'Credit Spreads Explained', Lehman Brothers European Fixed Income Research - March 2004, D. O'Kane

Real dirtyPriceFromZSpread (Spread zSpread, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date()) const

dirty price given Z-spread

Z-spread compounding, frequency, daycount are taken into account The default bond settlement is used if no date is given. For details on Z-spread refer to: 'Credit Spreads Explained', Lehman Brothers European Fixed Income Research - March 2004, D. O'Kane

virtual Real accruedAmount (Date d = Date()) const [virtual]

accrued amount at a given date

The default bond settlement is used if no date is given.

virtual Rate nextCoupon (Date d = Date()) const [virtual]

Expected next coupon: depending on (the bond and) the given date the coupon can be historic, deterministic or expected in a stochastic sense. When the bond settlement date is used the coupon is the already-fixed not-yet-paid one.

The current bond settlement is used if no date is given.

Rate previousCoupon (Date d = Date()) const

Previous coupon already paid at a given date.

Expected previous coupon: depending on (the bond and) the given date the coupon can be historic, deterministic or expected in a stochastic sense. When the bond settlement date is used the coupon is the last paid one.

The current bond settlement is used if no date is given.

void setupExpired () const [protected, virtual]

This method must leave the instrument in a consistent state when the expiration condition is met.

Reimplemented from Instrument.

void setupArguments (PricingEngine::arguments *) const [protected, virtual]

When a derived argument structure is defined for an instrument, this method should be overridden to fill it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

Reimplemented in CallableBond, and CallableFixedRateBond.

void fetchResults (const PricingEngine::results * r) const [protected, virtual]

When a derived result structure is defined for an instrument, this method should be overridden to read from it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

void addRedemptionsToCashflows (const std::vector< Real > & redemptions = std::vector< Real >()) [protected]

This method can be called by derived classes in order to build redemption payments from the existing cash flows. It must be called after setting up the cashflows_ vector and will fill the notionalSchedule_, notionals_, and redemptions_ data members.

If given, the elements of the redemptions vector will multiply the amount of the redemption cash flow. The elements will be taken in base 100, i.e., a redemption equal to 100 does not modify the amount.

Precondition:

The cashflows_ vector must contain at least one coupon and must be sorted by date.

void setSingleRedemption (Real notional, Real redemption, const Date & date) [protected]

This method can be called by derived classes in order to build a bond with a single redemption payment. It will fill the notionalSchedule_, notionals_, and redemptions_ data members.
