When you hold shares that are registered directly with Air Liquide, you can place your stock market orders via your personal online Account (subject to have signed an account agreement), and thus benefit from a reduced brokerage rate of 0.10% before tax instead of 0.18% before tax for purchases paid in full by SEPA automatic debit (if the account is domiciled in the SEPA zone) or by bank card (for purchases below €3,000), as well as for sales.
