We have interests in various entities that are considered to be VIEs. The primary types of entities are securitization trusts guaranteed by us via lender swap and portfolio securitization transactions, mortgage and asset-backed trusts that were not created by us, as well as housing partnerships that are established to finance the acquisition, construction, development or rehabilitation of affordable multifamily and single-family housing. These interests include investments in securities issued by VIEs, such as Fannie Mae MBS created pursuant to our securitization transactions and our guaranty to the entity. We consolidate the substantial majority of our single-class securitization trusts.

As of June 30, 2011, we consolidated certain Fannie Mae securities that were not consolidated as of December 31, 2010 because we now hold in our portfolio a substantial portion of the certificates. As a result of consolidating these securities, which had combined total assets of $2.3 billion in unpaid principal balance as of June 30, 2011, we derecognized our investment in these trusts and recognized the assets and liabilities of the consolidated trusts at their fair value.

As of December 31, 2010, we consolidated VIEs that were no longer consolidated as of June 30, 2011. These VIEs were Fannie Mae securitization trusts and were deconsolidated because we no longer hold in our portfolio a substantial portion of the certificates. As a result of deconsolidating these trusts, which had combined total assets of $31 million in unpaid principal balance as of December 31, 2010, we derecognized the assets and liabilities of the trusts and recognized at fair value our retained interests as securities in our condensed consolidated balance sheet.

We also have interests in VIEs that we do not consolidate because we are not deemed to be the primary beneficiary. These unconsolidated VIEs include securitization trusts, as well as other investment entities. The following table displays the carrying amount and classification of our assets and liabilities that relate to our involvement with unconsolidated VIEs as of June 30, 2011 and December 31, 2010, as well as our maximum exposure to loss and the total assets of those unconsolidated VIEs.

__________

⁽¹⁾	Contains securities exposed through consolidation which may also represent an interest in other unconsolidated VIEs.

⁽²⁾	Certain prior period amounts have been reclassified to conform to the current period presentation.

Our maximum exposure to loss generally represents the greater of our recorded investment in the entity or the unpaid principal balance of the assets covered by our guaranty. However, our securities issued by Fannie Mae multi-class resecuritization trusts that are not consolidated do not give rise to any additional exposure to loss as we already consolidate the underlying collateral.

We issue Fannie Mae MBS through portfolio securitization transactions by transferring pools of mortgage loans or mortgage-related securities to one or more trusts or special purpose entities. We are considered to be the transferor when we transfer assets from our own portfolio in a portfolio securitization transaction. For the three months ended June 30, 2011 and 2010, the unpaid principal balance of portfolio securitizations was $27.3 billion and $15.1 billion, respectively. For the six months ended June 30, 2011 and 2010, the unpaid principal balance of portfolio securitizations was $56.6 billion and $32.9 billion, respectively.

The majority of our portfolio securitization transactions do not qualify for sale treatment. As a result, our continuing involvement in the form of guaranty assets and guaranty liabilities with assets that were transferred into unconsolidated trusts is not material. We report the assets and liabilities of consolidated trusts created via portfolio securitization transactions that do not qualify as sales in our condensed consolidated balance sheets.

The following table displays some key characteristics of the securities retained in unconsolidated portfolio securitization trusts.

We define “managed loans” as on-balance sheet mortgage loans as well as mortgage loans that we have securitized in unconsolidated portfolio securitization trusts. The following table displays the unpaid principal balances of managed loans, including those managed loans that are delinquent as of June 30, 2011 and December 31, 2010.

⁽¹⁾	Represents the unpaid principal balance of loans held for investment and loans held for sale for which we are no longer accruing interest and loans 90 days or more delinquent which are continuing to accrue interest.

We recognize assets obtained and liabilities incurred in a portfolio securitization at fair value. Proceeds from the initial sale of securities from portfolio securitizations were $513 million and $126 million for the three months ended June 30, 2011 and 2010, respectively. Proceeds from the initial sale of securities from portfolio securitizations were $621 million and $375 million for the six months ended June 30, 2011 and 2010, respectively. For the three and six months ended June 30, 2010, proceeds from the initial sale of securities were reduced by $338 million and $1.6 billion, respectively, from the amount previously disclosed, primarily related to deconsolidated REMICs that should have been presented as proceeds from issuance of long-term debt of consolidated trusts.
