Paragraphs:
Selling and Administrative Expenses. Selling and administrative expenses increased $124.2 million in 2019 compared to 2018. Our selling and administrative expenses by major expense type for 2019 and 2018 were as follows (dollars in thousands):
Selling and administrative expenses increased approximately 70 basis points as a percentage of net sales in 2019 compared to 2018. The increase in expenses reflects the addition of PCM to our North America and EMEA segments, effective August 30, 2019.
The addition of PCM and increased variable compensation resulting from increased sales and gross profit in 2019 compared to 2018 were the primary drivers for the $90.9 million increase in personnel costs. PCM was also the primary driver for year over year increases in facilities, travel and entertainment, and marketing expenses.
Depreciation and amortization expense increased approximately $8.8 million year over year, primarily due to additional amortization expense on newly acquired intangible assets.
