In 60 days, a bank plans to lend $10 million for 180 days. The lending rate is LIBOR plus 200 basis points. The current LIBOR is 4.5%. The bank buys an interest-rate put that matures in 60 days with a notional principal of $10 million, days in underlying of 180 days, and a strike rate of 4.3%. The put premium is $4,000. What is the effective annual rate of the loan if at expiration LIBOR = 4.1%? A) 0.0648. B) 0.0619. C) 0.0640.
This one is tricky 
thanks for the reality check
It is, but if you can nail these quantitative ?'s come exam day, it gives you a huge step up on the rest of the L3 herd.
It’s C,…I hope I am right…
I get something close to B. I’m probably wrong, but I’m still completely stoked that I retained enough from my first read of this SS last month to get an answer even close to to these!!
C
could you guys show your math? Edit: I’m an idiot, we’re lending not borrowing.
I also got C $4000* ((1+(.045+.02)*(60/360))= $4,043.33 Total loan was $10,004,043.33 Then 10,000,000*((0.041+.02)*(180/360))=$305,000 Put pay off = $10,000,000*((.043-.041)(180/360))= $10,000 So, $10,000,000+$305,000+$10,0000 = $10,315,000 $10,315,000/ $10,004,043.33= 1.0311 1.0311^(365/180)= 1.064-1=6.4% Hope that is the right answer.
Thanks Jeremy!
Your answer: C was correct! The effective amount the bank parts with or “lends” at time of the loan is: $10,004,043 = $10,000,000 + $4,000 × (1 + (0.045 + 0.02) × (60/360)) If LIBOR at maturity equals 4.1%, the payoff of the put would be: payoff = ($10,000,000) × [max(0, 0.043 – 0.041) × (180/360) payoff = $10,000 The dollar interest earned is: $305,000=$10,000,000 × (0.041 + 0.02) × (180/360), and EAR = ($10,000,000 + $10,000 +$305,000) / ($10,004,043) - 1 EAR = 0.0640 or 6.40% Good Job
Fear of EAR? Not shortcut but 100+ keystrokes(key-jokes) just to get a simple number close (LIBOR+Spread)?
I got C
bpdulog, without calculator? Difficult to guess answer on this one – the numbers given are so close.

Isn’t there a shortcut to estimate this?
thanks for posting the Q…reality check
Doesn’t save much, but it can give a very close number. (using put premium without interest) (1+EAR)^(180/365) = (1.0315/1.0004) EAR=6.4% --------------------------------------------------------------- Notes: 0.0315=(4.3%+2%)/2
