On 4 September 2014, the European Commission announced regulations 947/2014, 948/2014 and 949/2014 extending the annual intervention period for butter and skimmed milk powder from March-September to March-December.
The regulations also introduced private storage aid schemes for butter and skimmed milk powder. The aid shall be distributed in the following amounts for butter:

• 18.93EUR per tonne of storage for fixed storage costs
• 0.28EUR per tonne per day of contractual storage.

The following amounts will be made available for skimmed milk powder:

• 8.86EUR per tonne of storage for fixed storage costs
• 0.16EUR per tonne per day of contractual storage.
