The Big Four banks have reported their fourth quarter and full year earnings, and here’s a look at what happened in their mortgage space.

Bank of America

Noninterest expense, excluding litigation, declined to $1.1 billion in the fourth quarter of 2014, compared to $1.3 billion in the prior quarter and $1.8 billion in the year-ago quarter as the number of 60+ days delinquent loans was reduced to 189,000 from 221,000 in the prior quarter and 325,000 in the year-ago quarter.

The company originated $11.6 billion in first-lien residential mortgage loans and $3.4 billion in home equity lines during the fourth quarter of 2014, compared to $11.7 billion and $3.2 billion in the prior quarter.

The number of 60+ days delinquent first mortgage loans serviced by Legacy Assets and Servicing declined by 136,000 loans, or 42%, from the fourth quarter of 2013 to 189,000 loans.

Noninterest expense in LAS, excluding litigation, declined to $1.1 billion in the fourth quarter of 2014 from $1.8 billion in the year-ago quarter.

Consumer Real Estate Services reported a net loss of $397 million for the fourth quarter of 2014, compared to a net loss of $1.0 billion for the same period in 2013, driven primarily by lower litigation expense.

Wells Fargo

Wells Fargo & Company (WFC) reported diluted earnings per common share of $4.10 for 2014, up 5% from $3.89 in 2013.

Full year net income was $23.1 billion, compared with $21.9 billion in 2013. For fourth quarter 2014, net income was $5.7 billion, or $1.02 per share, compared with $5.6 billion, or $1.00 per share, for fourth quarter 2013.

Mortgage banking in the fourth quarter saw originations of $44 billion, down from $48 billion in the third quarter, and applications of $66 billion, up from $64 billion in the third quarter.

The banking giant had a residential mortgage servicing portfolio of $1.8 trillion; ratio of MSRs to related loans serviced for others was 75 basis points, compared with 82 basis points in prior quarter.

Citi

Citigroup (C) reported a net income of $350 million, or $0.06 per diluted share, on revenues of $17.8 billion for the fourth quarter 2014.

This is significantly down from a net income of $2.5 billion, or $0.77 per diluted share, on revenues of $17.8 billion for the fourth quarter 2013.

Legal and related expenses and repositioning charges totaled $3.5 billion in the current quarter, compared to $1 billion in the prior year period, which severely dented earnings.

In addition, Citigroup's loans were $645 billion as of quarter end, down 3% from the prior year period. On a constant dollar basis, Citigroup's loans declined by 1%, as continued declines in Citi Holdings, driven primarily by reductions in the North America mortgage portfolio, offset by 3% growth in Citicorp.

JPMorgan Chase & Co.

Mortgage activity for JPMorgan Chase & Co (JPM) improved in the fourth quarter, but quarterly and annual revenues were down, while net revenue for the year hit a record $21.8 billion.

JPMorgan reported net income for the fourth quarter of 2014 of $4.9 billion, compared with net income of $5.3 billion in the fourth quarter of 2013. Earnings per share were $1.19, compared with $1.3 in the fourth quarter of 2013. The firm had legal fees of $990 million in the quarter.

Revenue for the quarter was $23.6 billion, down 2% compared with the prior year. The firm’s return on tangible common equity for the fourth quarter of 2014 was 11%, compared with 14% in the prior year. Core loans increased by 8% compared with the prior year.

Mortgage activity in the fourth quarter was mixed.

Mortgage originations were $23 billion, down 1% from the prior year and up 8% from the prior quarter.

Mortgage banking net income was $338 million, a decrease of $255 million from the prior year, driven by higher provision for credit losses and lower net revenue, largely offset by lower noninterest expense.
