BRAD SMITH: Also, we're tracking Citigroup this morning. Citigroup shutting down its municipal bonds business. The bank told employees, in a memo that the business was no longer viable, according to several reports, aiming to complete the closure by the end of the first quarter. Yahoo Finance's David Hollerith has more on this. David, good to see you.

DAVID HOLLERITH: Hey, Brad. Yesterday, the bank's head of markets and interim head of banking said in this memo shared with us that the economics of the municipals business, the activities are no longer viable given their commitment to increase the firm's overall returns. So at a high level, this is right in line with or maybe just a piece of what Citi has been trying to do for years now since CEO Jane Fraser took over, which is a sweeping restructuring of the bank in order to return it to profitability.

Again, the municipals business is effective the business of banks helping local and state governments finance infrastructure projects like roads, bridges, and schools. And so in the Citi memo, the bank's had said that it will continue working with current municipals clients and it will also continue investment banking activities in private and public partnerships in sectors like transportation, and health care, and clean energy.

This decision comes after months review, the memo had said. And the municipals business in general is said to be ultra competitive and very dependent on timing with public policy. Generally, a tough place to make money from what I gather from other commercial bankers at a couple other big banks. So the wind down will be completed by the end of the quarter with employees in the municipal sales, trading, and banking unit set to leave in the coming months.

As Bloomberg initially reported, there has already been an exodus of bankers from the team to investment bank Jefferies. The move is reported to affect in the ballpark of 100 employees.
