[2] During 2012, $2.0 billion and $350 million of assets and liabilities were transferred from Level 1 to Level 2, and $785 million and $40 million of assets and liabilities were transferred from Level 2 to Level 1. Of the asset transfers from Level 1 to Level 2, $940 million was due to a restriction that became effective for a private equity investment during 2012, while $535 million of the transfers from Level 2 to Level 1 was due to the lapse of this restriction during 2012. The remaining transfers were the result of additional information associated with certain equities, derivative contracts and private equity investments.
[3] Gross transfers between Level 1 and Level 2 during 2011 were not significant.
[4] Amounts represent the impact of legally enforceable master netting agreements and also cash collateral held or placed with the same counterparties.
