The share of mortgages backed by Fannie Mae and Freddie Mac that are originated or serviced by non-bank companies has risen sharply in the last five years.

Non-depository firms that are unaffiliated with commercial banks originated less than 10 percent of single-family loans purchased by Fannie and Freddie in 2010.

But there has been a dramatic shift in loan originations for the government-sponsored enterprises, with non-banks generating nearly half of GSE business in 2015.
