In 1992 a study (RP/92/10) was performed to examine VCA
occurrences. The report found that VCAs had increased sharply
following the introduction of the AMATS system in late 1991.
The aim of this report is to provide updated information on the
VCA situation. As an update on the 1992 VCA report, the most recent
six-month period, January to June 1994, will be examined.
