Operating EBITDA decreased $91 million to $44 million due to lower revenue, higher agent commission splits and the absence of $22 million of net earnings related to the sale of our former mortgage joint venture, partially offset by lower employee costs. If you look at NRT, including the royalties it pays to RFG, NRT contributed $350 million of the company's $658 million of operating EBITDA for 2018. Cartus revenue decreased $4 million in 2018, primarily due to a decrease in international revenue.
