Banking syndicate credit facility
Pursuant to the terms of the credit facility with the banking syndicate, the Group has agreed to financial covenants relating to the leverage ratio (interest bearing debt / EBITDA) and interest coverage (EBITDA / interest costs). In accordance with these covenants, the leverage ratio should remain below 3.0, which can under certain circumstances be temporarily increased to a maximum of 3.5. The interest coverage should always exceed 4.0. Both covenants are tested quarterly on a 12-month rolling basis. The actual leverage ratio at year-end was 1.0 (2016: 1.1) and the actual interest coverage at year-end was 34.0 (2016: 24.5).
The Group has provided a mortgage on its premises in Malente, Germany for a EUR 3.7 million loan. No security is provided in relation to the EUR 150 million revolving Credit Facility.
Interest on the EUR 4.4 million other loans is based on fixed-term interest rates. Interest amounts payable on the EUR 150 million revolving Credit Facility are based on short-term interest rate (mainly three months). See note 15 and accounting policy r for further details.
