In order to boost the financing structure still further, in December 2007, ABAP Beteiligungs Holding GmbH (after a change of issuer in 2019 today PORR AG) issued profit-participation rights for an unspecified length. Currently the total nominal value lies by EUR 40m and the interest amounted to 6,66% per annum until 31st December 2020. From 1st January 2021 until 31st December 2025 the interest will be 6.0% p.a..This is known as so-called hybrid capital, which is classified in the IFRS consolidated accounts as equity. This step resulted in the further diversification of financing sources.
