Ok, then, so it's just the reverse. I don't multiply it by the number listed. I multiply it by the exchange. Ok, that's really close to 10k, but not over, so I should be good then.

And I know I've seen this written before, but just in case:
Say I had 4,800 pounds in a savings acount. On the same date, I got deposits into my checking account that brought it to a high of £2,800. So, a total of £7,600 is what I could have gotten if I had gone in and liquidated both accounts on that date. £7,600 x $1.28 = $9,728. No FBAR required.
I moved £1,200 from the checking to the savings account on that date. I still only have a total of £7,600 in both accounts, total, but if you look at the highest amount on that day in each account it looks like I have £6,000 in savings and a high of £2,800 in checking, for a total of £8,600 for that day.
I keep thinking I remember seeing conversations go by that say I have to use the higher amount in figuring the FBAR. Is that correct, or is the actual amount available to me if I cashed out both accounts on that day the correct number to use?
