Please note that over the forthcoming holiday period, all EPO sites
will be closed from 24 December 2021 to 2 January 2022 inclusive.
This will affect fee processing as follows:

Replenishments will continue to be
automatically credited to your deposit account, provided that the deposit account number is correctly quoted
in the reference field of the bank transfer (e.g. “replenishment 28XXXXXX”, “repl28XXXXXX”
or “deposit 28XXXXXX”). If this important information is missing, you
may receive an (automatic)
notification of insufficient funds. In this case a manual processing of the replenishment will be performed retroactively
at the earliest on 3 January 2022.

Replenishments, pending orders and the payment
plan will continue to be visible in the Online Fee Payment tool and debit orders will be effectively booked during
the EPO closure period, provided sufficient funds are available.

Pending refunds can continue to be
claimed online. Refunds to EPO deposit
accounts will be visible online the next day, whereas refunds
to bank accounts will only be effectively executed with the next planned
payment run after the closure
period, i.e. as from 3 January 2022.

Year-end closing is expected to be completed by 14 January 2022.
In accordance with point 4.2 of the Arrangements for
deposit accounts
, once the financial
year is closed, a balance confirmation stating
the year-end balance of the deposit account will be sent to all deposit
account holders by post.
