MTM of forward contract - CFAI vs Schweser

Hi Guys

I am absolutely baffled as to the solution of finding the MTM of a forward contract in Schweser, vs how it is displayed in CFAI.

The Schweser formula just does not work on the CFAI text questions and I can’t understand why - I find the bid/offer rates correctly and derive every other component fine but just don’t get the right answer!

Schweser Formula - (FPT-FP) x Contract size/1+r(price currency)xdays/360

Can somebody please apply this to the following question?

You originally sell NZD 10MM at 0.79 USD/NZD. Now you want to mark this position to market.

Spot rate (USD/NZD) 0.7825/0.7830

The month points -12.1/-10.0

What is the mark to market?

I would really appreciate any help!!

Regards,
