margin transaction, IRR

Hi everyone,

I have two questions on the below problem which is taken from an example in Schweser

shs purchased: 1000

purchase prise per shs: 100 usd

annual dividend per shs: 2usd

inital margin requirement: 40%

call money rate: 4%

commmission per share: 0.05usd

stock price after one year: 110usd

I am used to make these calulcations thanks to the CF function:

Cfo: -40’000 (inital margini) -50 (comission)

Cf1: -60’000-2400(call money interest that the client has to pay)+110’000 (stock value at the end)+2000(dividends)-50(comission)

note: that’s the solution presented in Schweser

What I don’t understand is why there is 2 times the - 50 USD. I thought that “one 50” at the beginning (in the Cfo) would be sufficient. When it’s presented like this, I have the impression that the clients pays the comission twice.

Thanks

The client does pay commission twice. CF0 is them purchasing the security. CF1 is them selling the security. They are paying commission for both transactions

Seems legit. Thank you and have a nice WE.
