Most of the change in “Personnel expense” is due to the appreciation of the US dollar against the Euro.

“Indirect taxes” consist mostly of sales tax in North America.

The change in “Withholding taxes” reflects withholding on the dividends paid by the subsidiary HMSHost Corporation ($ 5m).

The heading “Other” includes amounts due to directors and statutory auditors (€ 1,000k), as well as deferred promotional contributions from suppliers and accrued liabilities for insurance, utilities, and maintenance pertaining to 2015. Most of the change concerns the reversal of promotional contributions from suppliers pertaining to 2015.
