Option pricing with transaction costs (Excel)

Today we are investigating an extension of Black-Scholes option pricing model that relaxes the assumption of no transaction costs which has been developed by Leland (1985). We are going to discuss the mathematical and financial concepts behind the Leland (1985) model, its Excel implementation as well as its implications for option trading.

if a bank grants a loan with 2 % margin + variable euribor12M, repricing once in a year, and bank makes additional condition on if euribor below zero, variable part automatically set as zero, would you consider this as an market option keeping in mind that the bank will have the loan till it is fully covered (some consider this as an market option, I consider that the loan with such condition creates additional interest then euribor is below zero in comparison to the loan which does not have zero limit for euribor - therefore loan of such type has more economic value, but in times of positive euribor the difference would be zero), what would be your view in this case?
