[1] New Residential generally obtains pricing service quotations or broker quotations from two sources, one of which is generally the seller (the party that sold New Residential the security) for Non-Agency RMBS. New Residential evaluates quotes received and determines one as being most representative of fair value, and does not use an average of the quotes. Even if New Residential receives two or more quotes on a particular security that come from non-selling brokers or pricing services, it does not use an average because it believes using an actual quote more closely represents a transactable price for the security than an average level. Furthermore, in some cases there is a wide disparity between the quotes New Residential receives. New Residential believes using an average of the quotes in these cases would not represent the fair value of the asset. Based on New Residential’s own fair value analysis, it selects one of the quotes which is believed to more accurately reflect fair value. New Residential has not adjusted any of the quotes received in the periods presented. These quotations are generally received via email and contain disclaimers which state that they are “indicative” and not “actionable” — meaning that the party giving the quotation is not bound to actually purchase the security at the quoted price. New Residential’s investments in Agency RMBS are classified within Level 2 of the fair value hierarchy because the market for these securities is very active and market prices are readily observable.The third-party pricing services and brokers engaged by New Residential (collectively, “valuation providers”) use either the income approach or the market approach, or a combination of the two, in arriving at their estimated valuations of RMBS. Valuation providers using the market approach generally look at prices and other relevant information generated by market transactions involving identical or comparable assets. Valuation providers using the income approach create pricing models that generally incorporate such assumptions as discount rates, expected prepayment rates, expected default rates and expected loss severities. New Residential has reviewed the methodologies utilized by its valuation providers and has found them to be consistent with GAAP requirements. In addition to obtaining multiple quotations, when available, and reviewing the valuation methodologies of its valuation providers, New Residential creates its own internal pricing models for Level 3 securities and uses the outputs of these models as part of its process of evaluating the fair value estimates it receives from its valuation providers. These models incorporate the same types of assumptions as the models used by the valuation providers, but the assumptions are developed independently. These assumptions are regularly refined and updated at least quarterly by New Residential, and reviewed by its valuation group, which is separate from its investment acquisition and management group, to reflect market developments and actual performance.For 67.6% of our Non-Agency RMBS, the ranges of assumptions used by New Residential’s valuation providers are summarized in the table below. The assumptions used by New Residential’s valuation providers with respect to the remainder of New Residential’s Non-Agency RMBS were not readily available.
