Fannie Mae issued approximately $28.5 billion in multifamily mortgage-backed securities in 2013, completing the year with multifamily MBS issuance of $7 billion in the fourth quarter, the government-sponsored enterprise said.

Last year, Fannie Mae issued $33.1 billion total in MBS issuance and resecuritized $2.3 billion of DUS MBS through the Fannie Mae Guaranteed Multifamily Structures program in the fourth quarter.

"It was a successful year for the DUS program with MBS issuance reaching $28.5 billion," said Manny Menendez, senior vice president of multifamily capital markets & pricing with Fannie Mae. 

"We continued to expand the investor base for DUS through the issuance of GeMS, which had a record year with $10.2 billion of total issuance. We are looking forward to another strong year in 2014."
