Options on Three-Month Canadian Bankers' Acceptance Futures (OBW, OBX, OBY, OBZ)

Underlying

For regular options (OBX), the underlying BAX contract is the futures contract that expires during the month in which the option expires.

For serial mid-curve options (OBW), the underlying is the BAX contract that expires one year from the next quarterly month that is nearest to the expiration of the option. For example, the underlying for the one-year mid-curve option that expires in January or February is the March BAX contract of the next calendar year.

For one-year and two-year quarterly mid-curve options (OBY and OBZ), the underlying is the corresponding BAX contract that expires one year (for OBY) or two years (for OBZ) after the option expires. For example, the underlying for the one-year quarterly mid-curve option that expires in June is the June BAX contract of the next calendar year.
