(a) Information received from third-party valuation service providers. The ranges of the unobservable inputs for constant prepayment rate, loss severity and constant default rate relate to each of the individual underlying mortgage loans that comprise the entire portfolio of securities in the RMBS and CDO securitization vehicles and not necessarily to the securitization vehicle bonds (tranches) purchased by us. The ranges of these inputs do not directly correlate to changes in the fair values of the tranches purchased by us, because there are other factors relevant to the fair values of specific tranches owned by us including, but not limited to, purchase price, position in the waterfall, senior versus subordinated position and attachment points.

(b) Represents discount rates, estimates and assumptions that we believe would be used by market participants when valuing these assets and liabilities.

(c) Mortality inputs are shown as multipliers of the 2012 Individual Annuity Mortality Basic table for GMWB, and the 1975-1980 Modified Basic Table for index annuities.
