(15)Article 69, point (a)(i), of Delegated Regulation (EU) 2015/35 provides that paid-in ordinary shares capital and the related share premium account are eligible as tier 1 basic own-fund items where their repayment or redemption is subject to prior supervisory approval. Such a requirement may create undue administrative and regulatory burden where an insurance or reinsurance undertaking executes a share buy-back programme with the objective of immediately using the bought shares for the exercise stock options. It should therefore be specified that where the repayment or redemption of basic own fund items aims at exercising stock option rights within no more than one month from the date of the share buyback, such repayment or redemption should not be subject to prior supervisory approval.
