Set Call Exercise Policy for Option Embedded Fixed Bond Instrument

This example shows how to use setCallExercisePolicy to maintain consistency between the exercise schedule and exercise style when using a OptionEmbeddedFixedBond instrument object.

Create OptionEmbeddedFixedBond Instrument Object

Use fininstrument to create an OptionEmbeddedFixedBond instrument object with different exercise styles.

Maturity = datetime(2024,1,1);
Strike = [100;100];
ExerciseDates = [datetime(2020,1,1); datetime(2024,1,1)];
Period = 1;
CallSchedule =  timetable(ExerciseDates,Strike,'VariableNames',{'Strike Schedule'}); 

CallableBond = fininstrument("OptionEmbeddedFixedBond",'Maturity',Maturity,...
                              'CouponRate',0.025,'Period',Period, ...
                              'CallSchedule',CallSchedule)

CallableBond = 
  OptionEmbeddedFixedBond with properties:

                  CouponRate: 0.0250
                      Period: 1

            PutExerciseStyle: [0x0 string]
                        Name: ""

Set the Exercise Style to Bermudan

Use setCallExercisePolicy to define the CallExerciseStyle as Bermudan.

CallableBond = setCallExercisePolicy(CallableBond, CallSchedule, "Bermudan") 

CallableBond = 
  OptionEmbeddedFixedBond with properties:

                  CouponRate: 0.0250
                      Period: 1
                       Basis: 0

              LastCouponDate: NaT
                   StartDate: NaT
                    Maturity: 01-Jan-2024

            PutExerciseStyle: [0x0 string]
                        Name: ""

Use setCallExercisePolicy to modify CallSchedule and continue using a Bermudan exercise style.

Strike = [100; 101;102;103];
ExerciseDates = [datetime(2018,1,1);datetime(2020,1,1);datetime(2022,1,1);datetime(2024,1,1)];

CallSchedule =  timetable(ExerciseDates,Strike,'VariableNames',{'Strike Schedule'}); 

CallableBond = setCallExercisePolicy(CallableBond, CallSchedule)   

CallableBond = 
  OptionEmbeddedFixedBond with properties:

                  CouponRate: 0.0250
                      Period: 1

Set Call Exercise Policy for Specific Option Embedded Fixed Bond Instrument

This example shows how to use setCallExercisePolicy to maintain consistency between the exercise schedule and exercise style when using a OptionEmbeddedFixedBond instrument object with three OptionEmbeddedFixedBond instruments.

Create OptionEmbeddedFixedBond Instrument Object

Use fininstrument to create an OptionEmbeddedFixedBond instrument object for three Option Embedded Fixed Bond instruments with American exercise styles.

Maturity = datetime([2024,1,1 ; 2024,4,1 ; 2024,8,1]);
Strike = [100;100];
ExerciseDates = [datetime(2020,1,1); datetime(2024,1,1)];
Period = 1;
CallSchedule =  timetable(ExerciseDates,Strike,'VariableNames',{'Strike Schedule'}); 

CallableBond = fininstrument("OptionEmbeddedFixedBond",'Maturity',Maturity,...
                              'CouponRate',0.025,'Period',Period, ...
                              'CallSchedule',CallSchedule)

CallableBond=3×1 OptionEmbeddedFixedBond array with properties:
    CouponRate
    Period
    Basis
    EndMonthRule
    Principal
    DaycountAdjustedCashFlow
    BusinessDayConvention
    Holidays
    IssueDate
    FirstCouponDate
    LastCouponDate
    StartDate
    Maturity
    CallDates
    PutDates
    CallSchedule
    PutSchedule
    CallExerciseStyle
    PutExerciseStyle
    Name

CallableBond.CallExerciseStyle

ans = 
"american"

ans = 
"american"

ans = 
"american"

The CallExerciseStyle is "American" because the fininstrument syntax does not contain a CallExercideStyle specification and there are two exercise dates defined in the CallSchedule.

Set the Exercise Style to Bermudan

Use setCallExercisePolicy to define the CallExerciseStyle as Bermudan for the second (CallableBond(2)) instrument.

CallableBond(2) = setCallExercisePolicy(CallableBond(2), CallSchedule, "Bermudan") 

CallableBond=3×1 OptionEmbeddedFixedBond array with properties:
    CouponRate
    Period
    Basis
    EndMonthRule
    Principal
    DaycountAdjustedCashFlow
    BusinessDayConvention
    Holidays
    IssueDate
    FirstCouponDate
    LastCouponDate
    StartDate
    Maturity
    CallDates
    PutDates
    CallSchedule
    PutSchedule
    CallExerciseStyle
    PutExerciseStyle
    Name

CallableBond.CallExerciseStyle

ans = 
"american"

ans = 
"bermudan"

ans = 
"american"

Use setCallExercisePolicy to modify CallSchedule and continue using a Bermudan exercise style.

Strike = [100; 101;102;103];
ExerciseDates = [datetime(2018,1,1);datetime(2020,1,1);datetime(2022,1,1);datetime(2024,1,1)];

CallSchedule =  timetable(ExerciseDates,Strike,'VariableNames',{'Strike Schedule'}); 

CallableBond(2) = setCallExercisePolicy(CallableBond(2), CallSchedule)

CallableBond=3×1 OptionEmbeddedFixedBond array with properties:
    CouponRate
    Period
    Basis
    EndMonthRule
    Principal
    DaycountAdjustedCashFlow
    BusinessDayConvention
    Holidays
    IssueDate
    FirstCouponDate
    LastCouponDate

ans = 
"american"
