Detailed Description

Callable bond base class.

Base callable bond class for fixed and zero coupon bonds. Defines commonalities between fixed and zero coupon callable bonds. At present, only European and Bermudan put/call schedules supported (no American optionality), as defined by the Callability class.

Definition at line 53 of file callablebond.hpp.

Constructor & Destructor Documentation

◆ CallableBond()

CallableBond	(	Natural	settlementDays,
		const Date &	maturityDate,
		const Calendar &	calendar,
		DayCounter	paymentDayCounter,
		Real	faceAmount,
		const Date &	issueDate = `Date()`,
		CallabilitySchedule	putCallSchedule = `CallabilitySchedule()`
	)

Definition at line 30 of file callablebond.cpp.

Here is the call graph for this function:

Member Function Documentation

◆ callability()

const CallabilitySchedule & callability ( ) const

return the bond's put/call schedule

Definition at line 62 of file callablebond.hpp.

◆ impliedVolatility()

Volatility impliedVolatility	(	const Bond::Price &	targetPrice,
		const Handle< YieldTermStructure > &	discountCurve,
		Real	accuracy,
		Size	maxEvaluations,
		Volatility	minVol,
		Volatility	maxVol
	)		const

returns the Black implied forward yield volatility

the forward yield volatility, see Hull, Fourth Edition, Chapter 20, pg 536). Relevant only to European put/call schedules

Definition at line 112 of file callablebond.cpp.

Here is the call graph for this function:

◆ OAS()

Spread OAS	(	Real	cleanPrice,
		const Handle< YieldTermStructure > &	engineTS,
		const DayCounter &	dayCounter,
		Compounding	compounding,
		Frequency	frequency,
		Date	settlementDate = `Date()`,
		Real	accuracy = `1.0e-10`,
		Size	maxIterations = `100`,
		Rate	guess = `0.0`
	)

Calculate the Option Adjusted Spread (OAS)

Calculates the spread that needs to be added to the reference curve so that the theoretical model value matches the marketPrice.

Definition at line 279 of file callablebond.cpp.

Here is the call graph for this function:

◆ cleanPriceOAS()

Real cleanPriceOAS	(	Real	oas,
		const Handle< YieldTermStructure > &	engineTS,
		const DayCounter &	dayCounter,
		Compounding	compounding,
		Frequency	frequency,
		Date	settlementDate = `Date()`
	)

Calculate the clean price based on the given option-adjust-spread (oas) over the given yield term structure (engineTS)

Definition at line 313 of file callablebond.cpp.

◆ effectiveDuration()

Real effectiveDuration	(	Real	oas,
		const Handle< YieldTermStructure > &	engineTS,
		const DayCounter &	dayCounter,
		Compounding	compounding,
		Frequency	frequency,
		Real	bump = `2e-4`
	)

Calculate the effective duration, i.e., the first differential of the dirty price w.r.t. a parallel shift of the yield term structure divided by current dirty price

Definition at line 337 of file callablebond.cpp.

◆ effectiveConvexity()

Real effectiveConvexity	(	Real	oas,
		const Handle< YieldTermStructure > &	engineTS,
		const DayCounter &	dayCounter,
		Compounding	compounding,
		Frequency	frequency,
		Real	bump = `2e-4`
	)

Calculate the effective convexity, i.e., the second differential of the dirty price w.r.t. a parallel shift of the yield term structure divided by current dirty price

Definition at line 369 of file callablebond.cpp.

◆ setupArguments()

void setupArguments ( PricingEngine::arguments * ) const

overridevirtual

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.

Definition at line 403 of file callablebond.cpp.

◆ accrued()
