Ann: Security Class Reinstatement to Quotation- OPTOB, page-11

also time value I referred to earlier is options time value not time value of money.

given OPTB is far out of the money - the current options price would be all time value (10c).

for example - If magically OPT SP is $2 today then OPTB should be worth $2.10

therefore - i think you analysis does not factor in the time value of the option therefore a bit more upside maybe needs to be factored into your model
