Standard & Poor's changed equity content of TenneT's hybrid capital, A- credit rating re-confirmed

Downloads & Contact

In a statement published yesterday, Standard & Poor’s Ratings Services (“S&Ps”) announced that it has revised the equity content from ‘Intermediate’ (50%) to ‘Minimal’ (0%) for a number of corporate hybrid capital transactions. This is also applicable to TenneT's outstanding hybrid capital instrument (ISIN XS0484213268). Despite the revised equity content assigned, S&P has also affirmed TenneT's long-term corporate credit rating at A-.

Knowing that the current terms and conditions of the Hybrid have been acceptable for S&Ps since issuance in February 2010 and no prior indication of a review had been given, TenneT sees no fundamental reason for this unexpected step by S&P.

TenneT considers hybrid capital to be an important element of TenneT's capital structure and therefore TenneT is considering alternatives to address S&Ps concerns, which could potentially result in the restoration of the ‘Intermediate’ equity content for the Hybrid. TenneT will update the market in due course.
