Standard&Poor's Ratings Services raised the short-term component of its rating on the Colorado Housing And Finance Authority's multifamily bonds series 2005A-2 and single-family bonds series 2003C-2 (AAA/A-1+) to 'A-1+' from 'A-2', reflecting the substitution of standby bond purchase agreements (SBPA) on both series on Nov. 23, 2011. The authority will substitute an SBPA from Barclays Bank PLC (AA-/A-1+) for an SBPA from Dexia Credit Local (A-/A-2) on the 2005A-2 multifamily bonds and an SBPA from the Royal Bank of Canada (AA-/A-1+) for an SBPA from Dexia Credit Local on the 2003C-2 single-family bonds. Both ratings remain on CreditWatch with negative implications. The new SBPA for the series 2005A-2 bonds will expire Sept. 6, 2012, unless terminated earlier in
