Pricing Convertible Bonds: Ultimate Convertible Bond Pricing Model

The Ultimate Convertible Bond Pricing Model is an off-the-shelf solution that employs a partial differential equation (PDE) methodology for valuing a full range of convertible bonds. The Ultimate Convertible Bond Pricing Model accurately captures dividends and provides much smoother and faster convergence than tree-based approaches. The model provides comprehensive support for CBs with the standard range of features including:

pricing convertible bonds

  • Fixed, proportional, or mixed fixed/proportional dividend models. Explicit dividend schedules or internally built.

  • Hazard rates calibrated from CDS spreads (or exogenous user input).  

  • Fixed, floating or mixed fixed/floating coupon models. Explicit coupon date schedules or internally built.  

  • Separate treasury and benchmark curves.   

  • Convertibles written on foreign stocks.  

  • Hard call and discrete put schedules.  

  • M of N soft calls with arbitrary number of days for the soft call trigger and soft call window including time variable call price/protection price schedules.  

  • Contingent conversion (COCOs), conversion ratio resets, with pertinent parameters time variable according to user defined schedules.  

  • Many types of make whole provisions including make whole conversion ratio adjustment matrices and change of control provisions.  

  • Funding spread, borrow rate, choice of day count basis and holiday calendar support, switches for inclusion of accrued interest upon call, conversion, put, or default.  

  • Outputs include theoretical price, all standard Greeks, interest, hazard, credit spread curve sensitivities, and many market implied quantities.

Test drive the Ultimate Convertible Bond Pricing Model

Output Data


  • Clean, dirty prices, accrued interest
  • Parity, premium
  • Straight bond price

Sensitivities (computation controlled by switches):

  • Delta, gamma, theta
  • Change in implied vol (vega, volga, vanna)
  • Parallel shift of yield curve
  • Change in borrow rate
  • Change in hazard rate

Implieds (computation controlled by switches):

  • Implied vol given hazard rate and market price
  • Implied hazard rate given vol and market price
