Operating expenses in the first quarter of 2019 decreased 5.2% period-over-period, primarily as a result of our disposition activity in the third quarter of 2018 and the weakening of substantially all foreign currencies against the U.S. Dollar. Salary and service costs, which tend to fluctuate with changes in revenue, decreased $145.2 million, or 5.4%, in the first quarter of 2019 compared to the first quarter of 2018. Occupancy and other costs, which are less directly linked to changes in revenue than salary and service costs, decreased $11.1 million, or 3.5%, in the first quarter of 2019 compared to the first quarter of 2018. Operating margin for the first quarter of 2019 was 12.4% compared to 11.6% for the first quarter of 2018. The period-over-period increase primarily reflects a change in the mix of our business during the current period, including the positive effects following the disposition of underperforming businesses in the current and prior year and our repositioning activity in the third quarter of 2018, as well as our ongoing efforts to manage our cost structure and increase the efficiency of the operations of our agencies. In addition, a net gain on the sale of certain businesses during the quarter, partially offset by the negative impact of foreign exchange rates, marginally improved earnings before interest, taxes and amortization of intangible assets, or EBITA, margin and operating profit in the current period. EBITA margin for the first quarter of 2019 was 13.0% compared to 12.4% for the first quarter of 2018.
