Register substantial holdings and gross short positions

This overview shows all substantial holdings and gross short positions in issuing institutions and shares with special controlling rights.

An issuing institution is: a public limited company (naamloze vennootschap) incorporated under Dutch law whose (depositary receipts for) shares are admitted to trading on a regulated market in the Netherlands or in another Member State of the European Union or an EEA State, or a legal entity incorporated under the law of a state that is not an EU Member State and whose (depositary receipts for) shares are admitted to trading on a regulated market in the Netherlands.

As soon as the substantial holding or short position equals or exceeds 3% of the issued capital, the holder should report this. Subsequently, he should notify the AFM again when his substantial holding or short position consequently reaches, exceeds or falls below a threshold. This can be caused by the acquisition or disposal of shares by the shareholder or because the issued capital of the issuing institution is increased or decreased. Thresholds are: 3%, 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 75% en 95%.

The duty to notify applies to legal entities as well as natural persons.
