This website contains links to websites of third parties ("external links"). These websites are subject to the liability of the respective provider. When setting the external links for the first time, the provider checked the external website contents for any statutory violations. At the time of setting the link no statutory violations were evident. The provider has no influence whatsoever on the current and future design and contents of the linked pages. The setting of external links does not mean that the provider adopts the contents of the reference or link. Without any actual indications with regard to statutory violations, a regular check of the external links cannot be expected of the provider. If statutory violations become known, however, such external links will be deleted immediately.
