195 The composition of Aegon Americas, Aegon the Netherlands and Aegon UK’s bond impairment losses and recoveries by issuer for  the periods ended December 31, 2013 and December 31, 2012 is presented in the table below. Those issuers with impairments or  recoveries above EUR 25 million are specifically noted.  Net impairments during 2013 totaled EUR 71 million, including EUR 66 million (2012: EUR 120 million) of gross impairments related  to residential mortgage backed securities in the Americas. During 2013, Aegon recognized EUR 60 million (2012: EUR 54 million) in recoveries on previously impaired securities. In each case  where a recovery was taken on structured securities, improvements in underlying cash flows for the security were documented  and modeling results improved significantly. Recoveries on non-structured securities were supported by documented credit events  combined with significant market value improvements. The tables that follow provide information on past due and individually impaired financial assets for the whole Aegon Group. An asset  is past due when a counterparty has failed to make a payment when contractually due. Assets are impaired when an impairment loss  has been charged to the income statement relating to this asset. After the impairment loss is reversed in subsequent periods, the asset  is no longer considered to be impaired. When the terms and conditions of financial assets have been renegotiated, the terms and  conditions of the new agreement apply in determining whether the financial assets are past due. Aegon's policy is to pursue realization of the collateral in an orderly manner as and when liquidity permits. Aegon generally does not  use the non-cash collateral for its own operations.
