With a total of 215.8 million euros in 2018, the net revenue from traffic increased by 3.4% compared with the previous year. Prices have not been raised, but ticket sales have increased in volume. Subscriptions at preferential tariffs have increased the most (28%). Rental income increased by 10% thanks to the new occupancy agreements with shops in stations. Miscellaneous revenue (revenue from surcharges, recoveries on claims, etc.) increased by 31%. Advertising revenue dropped slightly (by 1%) following the revision of the ethical charter, which has become more restrictive.
In 2018, the business's operating expenses were €587.8 million. Salary costs (€458.2 million) were slightly up on 2017 following the increase in the workforce and the indexing of salaries. 2018 was characterised by a major reversal of provision following the conclusion of agreements on various disputes on ongoing projects, and a decrease in pre-retirement provisions.
STIB monitors the development of its "ESA" coverage ratio, calculated using the method recommended by the Institute of National Accounts. This ratio does not take into account expense and income items. In 2018, the coverage ratio of the company's expenses from its own income, excluding subsidies, reached 40.2%. Since 2014, the annual allocation that enables STIB to improve its transport offer has been considered a subsidy, not a transport service remuneration. It is therefore excluded from the calculation. Consequently, this has a downward impact on the coverage ratio as spending has increased at a faster rate than the traffic revenues, which do not cover all the transport costs.
