7. PHC Certificates

The Partnership owned 100% of the Residual Participation Receipts (“LIFERs”) in three tender option bond trusts (“PHC TOB Trusts”) that contain the PHC Certificates. The assets held by the PHC Trusts consist of custodial receipts evidencing loans made to a number of local public housing authorities. Principal and interest on these loans are payable by the respective public housing authorities out of annual appropriations to be made to the public housing authorities by HUD under HUD’s Capital Fund Program established under the Quality Housing and Work Responsibility Act of 1998 (the “Capital Fund Program”). The PHC Trusts have a first lien on these annual Capital Fund Program payments to secure the public housing authorities’ respective obligations to pay principal and interest on their loans. The loans payable by the public housing authorities are not debts of, or guaranteed by, the United States of America or HUD. Interest payable on the public housing authority debt held by the PHC Trusts is exempt from federal income taxes. The PHC Certificates issued by each of the PHC Trusts have been rated investment grade by Standard & Poor’s.

See Note 22 for a description of the methodology and significant assumptions for determining the fair value of the PHC Certificates. Unrealized gains or losses on the PHC Certificates are recorded in the condensed consolidated statements of comprehensive income (loss) to reflect changes in their estimated fair values resulting from market conditions and fluctuations in the present value of the expected cash flows from the PHC Certificates.
