"Servicing: Expansion of Servicing and Subservicing Our Servicing segment expanded its servicing portfolio by 15% in the first quarter of 2019 largely due to the acquisition of Pacific Union and execution of a subservicing contract for $42 billion UPB in mortgages. As of March 31, 2019, we serviced 3.8 million customers with an outstanding UPB of $632 billion."
