breaks in unadjusted, calendar adjusted and/or seasonally adjusted time
series as well as revisions covering longer time intervals than usually in
the unadjusted data should also trigger the system.
5. If the restructuring effects on official statistics take place over a longer
time, the total size of the effects should be taken into account – not just
the effects on single data releases.
6. The granularity of the data published as European statistics should be
taken into account (e.g. the breakdown of the data published according
to the NACE Rev. 2 classification).
7. The focus of the EWS should be on the restructuring within MNEs
especially since these are more difficult to detect and information on
them is more difficult to obtain.
8. Restructuring between MNEs (e.g. mergers and acquisitions) might also
be dealt with in the EWS.
9. Triggering the EWS by a national EWS correspondent is also possible for
cases that come to the correspondent's attention but do not directly
affect his/her own country.
10. Generally, the EWS network may be consulted whenever national data
compilers are in doubt regarding the correct treatment of specific
restructuring cases.

4. Information to be exchanged in the EWS
EWS correspondents should trigger the EWS as soon as they learn about
the restructuring of an MNE with possible sizeable effects on national and
European statistics. National data compilers should not wait until all facts
about such cases are available. The EWS could also be triggered by
information available at European level, for example by Eurostat or the ECB.
When triggering the EWS, national data compilers should attempt to
provide the following information:
1. A detailed description of the restructuring case (the description could
be drafted in an anonymised, stylized form "Company A opens a new
branch in country X ...").
2. The statistical domains/indicators affected (e.g. Short-term business
statistics, Structural business statistics, Balance of Payments, National
Accounts, ...).
3. The industries (NACE) affected (if possible for confidentiality reasons)
4. The estimated effects on the data (by statistical domain, if known).
5. Other countries that might be affected (if known).
6. Timing of the restructuring (when it took/ will take place).
7. The level of sensitivity (e.g. is the information based on a newspaper
article, has the concerned MNE agreed to the sharing of information,
...).
