while in the U.S. we are working our way through the impact of certain account-specific headwinds. Our overall performance continues to reflect our strong offerings and differentiated strategy, as well as the power of the ideas created by our talented people. Acxiom continues to perform consistent with our plan and we are seeing the benefit of our leadership position in data management capabilities,” said Michael I. Roth, Interpublic’s Chairman and CEO.

“As we enter our important fourth quarter, we are confident that our performance to date, and the current tone of business, have us on track to deliver growth at the high end of the 2019 target of 2%-to-3% organic net revenue growth. In addition, we continue to be comfortable with our target for adjusted EBITA margin expansion of 40-50 basis points over last year’s 13.5%.

66.8% in the first nine months of 2019 compared to 69.0% in the same period in 2018. Base salaries, benefits and tax, temporary help expenses and incentive expense all increased at rates less than net revenue growth. The improved ratio was primarily due to the inclusion of Acxiom, which has a lower ratio of salaries and related expenses as a percentage of its net revenue.

During the third quarter of 2019, office and other direct expenses were $367.9 million, an increase of 16.1% compared to the same period in 2018. During the first nine months of 2019, office and other direct expenses were $1.14 billion, an increase of 17.5% compared to the same period in 2018.

Office and other direct expenses were 17.8% of net revenue in the third quarter of 2019 compared to 16.7% a year ago, and were 18.5% in the first nine months of 2019 compared to 17.3% in the same period in 2018. The higher expense ratios are primarily due to the inclusion of Acxiom which has a higher ratio of office and other direct expenses as a percentage of its net revenue, mainly driven by client service costs.

During the third quarter of 2019, selling, general and administrative expenses of $9.8 million decreased 54.6% compared with the same period in 2018 and during the first nine months of 2019, selling, general and administrative expenses of $69.3 million decreased 18.9% compared to the same period in 2018. The decrease was primarily attributable to lower professional fees, mainly driven by transaction costs related to the acquisition of Acxiom in 2018.

Selling, general and administrative expenses were 0.5% of net revenue in the third quarter of 2019 compared to 1.1% a year ago, and were 1.1% in the first nine months of 2019 compared to 1.5% in the same period in 2018.

Depreciation and amortization increased 56.8% to $69.0 million during the third quarter of 2019 compared to a year ago, and increased 59.0% to $213.1 million in the first nine months of 2019 compared to a year ago, primarily due to the inclusion of Acxiom.

Depreciation and amortization as a percentage of net revenue was 3.3% in the third quarter of 2019 compared to 2.3% the same period in 2018, and was 3.4% in the first nine months of 2019 compared to 2.4% in the same period in 2018.

During the first nine months of 2019, restructuring charges were $33.9 million due to the implementation of a cost initiative to better align our cost structure with our revenue, primarily related to client losses occurring in 2018.

The income tax provision in the third quarter of 2019 was $64.6 million on income before income taxes of $232.7 million, compared to a provision of $60.7 million on income before income taxes of $224.1 million in the same period in 2018.
