The former CFO of Fannie Mae is not a fan of the GSE’s popular Connecticut Avenue Securities risk-sharing transactions, noting that the terms and pricing on recent CAS deals have worsened since the program began in 2013. Tim Howard, who left Fannie in 2004 and was involved in litigation regarding his tenure there, said the costs incurred don’t match the potential benefit, especially in the company’s latest transactions. Over the past three years, Fannie has issued $13.4 billion in CAS notes covering $467 billion in newly originated single-family mortgages. Howard said this leaves the company to pay about $7 billion over the next 10 years in premiums and hedging costs.
