The Quota Law for the five-year period 2007-2011 establishes two Additional Provisions which fix the complementary financial flows which have an effect on the net payable quota.
In particular, the First Additional Provision states that the First Additional Provision laid down in the 37/97 Law, August 4, which approves the methodology for determining the Quota of the Basque Country for the five-year period 1997-2001, remains in force. In the latter, certain "financial compensations" were established to meet the neutrality principle which inspired the negotiation to agree on the Excise Duties in 1997. The compensation amount is calculated by applying to the expected revenue (in the provisional quota) or actual revenue (in the final quota) for each product taxed in the Excise Duty, the difference between the attribution rate (6.24%) and the estimated percentage of consumption for the Basque Country (7.13% for Alcohol and on Alcohol and Alcoholic Beverages, on Intermediate Products and Beer, 6.56% on Mineral Oils and 4.4% on Manufactured Tobacco)
The Eighth Additional Provision establishes that, exclusively for the period 2017 to 2021, the result of the liability of the five-year period 2007 to 2011, the five-year period 2012 to 2016, and of the remaining agreements reached at the Economic Agreement Joint Committee meeting on 17 May 2017, which, as is known, marked the end of the discrepancies in the quota liabilities pursuant to Act 29/2007, shall be applied to offset the quota payable.
Finally, it should be noted that the meeting of the Economic Agreement Joint Committee on 19 July 2017 recognised the end of the agreement of the Economic Agreement Joint Committee reached on 16 January 2014, which established that, provisionally and given that the levying of the three new electricity sector taxes were assigned to the funding of the electricity tariff deficit, the amounts that the Provincial Councils collected from those taxes would be adjusted with the Spanish State.
