Business Continuity Planof JASDEC
Our Approach
JASDEC has regularly structured itself so that, in the eventof a disaster or other emergency, it would be able to continue
operations to the extent possible or promptly resume business
operations according to its Basic BCP policy. This is to minimize
the effect of such an emergency on JASDEC participants
and related entities as a settlement infrastructure.
The specific measures taken by JASDEC include formulatingconcrete action plans in advance. JASDEC has defined
actions to be taken in the event of a disaster or otheremergency, such as establishing the BCP Countermeasure
Office, delegated authority, organized emergency contact
networks, and so on. Our IT systems are installed in a robust
main center equipped with a private electrical generator, andour core systems are based on a redundant configuration.
Furthermore, we have built a backup center in a remotelocation to be prepared in case the main center becomes
unusable.

IT Backup System
Operations data of the main center is reflected at thebackup center almost in real time. In cases where the maincenter becomes unusable due to a disaster, infrastructure
failure ( excluding software failure ) or other such event, andthe restoration task is deemed to be time-consuming, thesystems will be switched over to the backup center.

Switchover to backup systems will take about 90 minutes.
Furthermore, to prepare for the prospect of the head officebuilding becoming unusable, we have established analternative office where we can execute operations asnecessary.

Main Initiatives in FY 2015
In FY 2015, we took the following steps to reinforce our business continuity plan ( BCP ).

BCP Exercises

Establishment of Osaka Office

We carried out several company-wide exercises, including
an employee safety confirmation exercise, and an exercise
involving the set-up of a BCP Countermeasure Office, as wellas an employee contact exercise based on a scenario in
which phone lines were congested. There were also activities
aimed at mitigating the damaging effects of disasters, including
in-house rescue training seminars by invited outside experts.
We also carried out training exercises with market participants,
such as data center switching drills with system users, andparticipated in a joint BCP exercise among three markets( securities market, money market, and forex market ), which
was conducted industry-wide.

In order to prevent the entire JASDEC organization frombeing affected at the same time by a wide-area disaster,
we established the Osaka Office as an alternative office inFebruary 2016. We constructed an operating structure
based on a dual site by assigning staff to the Osaka Officeeven in normal times.

Social Contribution Activities
As well as contributing to the economy
through our daily business activities, weengage in social contribution activities
based on direct employee participation,with the aim of improving people’s lives
