For the management of foreign securities and related cross-border settlement KELER concludes an account agreement with selected foreign custodians. Securities held by clients and securities in the portfolio of their clients are registered in a non-segregated manner at the foreign custodian of KELER. 
In addition to prevailing regulations the rules defined by the foreign custodian set the scope of foreign securities that KELER can accept. If foreign securities are issued in Hungary KELER undertakes the registration of the foreign securities based on the individual agreement concluded with the foreign custodian or clearing house. If the issuer lists foreign securities on the BSE that can be accepted by KELER, at the written request of the issuer KELER issues the statement of acceptance on stock exchange settlement based on the data held by the foreign custodian. Securities credited through the foreign custodian are shown as account receivables only on the account of the client, such securities cannot be physically delivered in or out.
