1. Undertakings designated as having significant market power may offer to the national regulatory authority commitments regarding conditions for access, co-investment, or both, applicable to their networks in relation, inter alia, to:

(a) cooperative arrangements relevant to the assessment of appropriate and proportionate obligations pursuant to Article 68;

(b) co-investment in very high capacity networks pursuant to Article 76; or

(c) effective and non-discriminatory access by third parties pursuant to Article 78, both during an implementation period of voluntary separation by a vertically integrated undertaking and after the proposed form of separation is implemented.

The offer for commitments shall be sufficiently detailed including as to the timing and scope of their implementation and their duration, to allow the national regulatory authority to undertake its assessment pursuant to paragraph 2 of this Article. Such commitments may extend beyond the periods for carrying out market analysis provided in Article 67(5).
