The Monthly Availability Payment

2.5.  Subject to paragraphs 2.6 to 2.7 of Part II of this Schedule 21 (Payment Mechanism), the Monthly Availability Payment payable by the Authority to the Service Provider shall be the Availability Payment applicable during each Payment Year divided by twelve (12).

2.6.  Where the issuance of the Core Investment Works Certificate or Expiry Date or any alteration to the Availability Payment (whether occurring at the end of any Payment Year or otherwise) falls part way through a Month, the Monthly Availability Payment will be calculated on a pro rata basis to reflect the number of Days in the Contract Month prior to the issuance of the Core Investment Works Certificate or Expiry Date or after alteration to the Availability Payment, as the case may be.
