the exact numbers are still in the processing, but the digest of the cash flow so far is that ID generated about 1750 BTC in its lifetime. 480 BTC are in the multi-sig address and about 120 BTC are floating around as additional reward reserve and not yet consolidated mining revenues. This is consistent with the fact that between February and May, ID accumulated about 650 BTC in surplus, and operated at break even thereafter. This means that ID upkeep consumed about 1150 BTC, the nature of it will be disclosed as soon as all transactions have been inspected.
