Fannie Mae Chief Financial Officer David Johnson plans to leave the company by yearend, according to a regulatory filing Tuesday.
Johnson informed the government-sponsored enterprise of his intentions on Friday, Fannie said.
David Hisey, deputy chief financial officer, will serve as interim CFO until a successor is named.
Johnson joined Fannie in November 2008 — two months after the GSE was placed into federal conservatorship — from the insurer Hartford Financial Services Group, where he also served as CFO.
He was Fannie's third CFO that year.
Earlier this month, Fannie reported a $3.46 billion loss for the third quarter, due in part to a $2.12 billion dividend it paid to the government.
Due to a deficit at the end of the quarter, it requested an additional $2.5 billion from the Treasury Department.
Still, the loss was considerably smaller than the nearly $20 billion loss posted in the third quarter of 2009, but it was slightly more than the $3.13 billion loss in the second quarter of this year.
The serious delinquency rate on single-family loans in its portfolio also improved, falling to 4.56% from 4.72% a year earlier.
The Obama administration is due to unveil its plans for the GSEs in January.
