Standard&Poor's Ratings Services affirmed its 'AA+' long-term rating on Wyoming Community Development Authority's (WCDA) single-family mortgage bonds issued under its 1978 indenture. The outlook is stable. The rating reflects our view of: Very strong asset-to-liability parity that stood at 145% as of Sept. 30, 2012; The strong credit quality of the single-family mortgage loans, which consist primarily of federally insured or guaranteed mortgage loans; High-quality investments; Reserves sufficient to cover potential liquidity and credit losses; and Good management oversight. The 'A-1+' rating on the 2001 series A, 2002 series A, and 2003 series B bonds reflects liquidity support for tenders provided by a standby bond purchase agreement from Bank of America N.A. (A/Negative/A-1), which expires on Oct. 20,
