Cash flow hedging

Hi,
I have just come across a question in which I have tried to apply the logic behind the video I have just watched on cash flow hedging but I am struggling..

A company enters into a derivative contract in order to protect cash inflows.
The FV of the instrument was nil at inception.
At the reporting date – the FV of the loss in respect of future cash flows was $9,100.

Explain the accounting treatment if the fair value of the hedging instrument was :

a) $8,500
b) $10,000

Sorry – I am struggling here – what is the $9,100? is that the loss in OCI. I cannot work this out at all, because I am struggling to see where the hedging item is – it doesn’t give any details on this.

Thanks
