Following the attack, Ethereum community, miners and exchanges leading the vote, decided to go hard-fork. After some code change and the upgrade of Ether clients, the hard-fork was completed on July 20th. Nearly 12 million ETH have been from the “Dark DAO” and “Whitehat DAO” contracts into the WithdrawDAO recovery contract.

DAO token sales
The DAO token sales start on . In the first 14 days, The DAO tokens were created at a rate of 1 ether = 100 tokens
In the subsequent days before the end of the creation period, the number of ethers for each 100 tokens created increases until the final rate of creation is 1.5 ethers = 100 tokens. The ETH amount in excess of 1 ETH per 100 DAOs was stored in The DAO's extraBalance account.
At the hard-fork block #1,920,000 , the ETH balance from The DAO and it's child DAOs (which includes the balance from the extraBalance account) were transferred into the Withdrawal contract. Immediately after the hard-fork, at block #1,920,090, the Withdrawal contact's trusteeWithdraw() function was called in this transaction to transfer 463,798.08818109 ETH into TheDAOCurator multisig wallet.
