Abstract: A method for allocating dairy end product pricing risk in a dairy production system is described. The method includes providing a fixed price for a future period for a dairy end product to a retailer of the dairy end product, determining a cost of production for the dairy end product, the cost of production including costs associated with each dairy production entity in the dairy production process, and allocating the difference between the fixed price and the cost of production among each dairy production entity based on the sale of the dairy end product at the fixed price.

Abstract: An ability to hold a record of amount of funds prepaid for at the point of the sale is incorporated within a subscriber identity module (or "SIM") of a mobile radio terminal. This payment record will progressively decrease as services of the network are used according to tarif rate which is either preprogrammed in to the SIM or sent by the network. The SIM monitors the remaining value of the payment and, when the value of the payment reaches a predetermined minimum value, prevents further calls. This blocking of the mobile station may be effected by a specific blocking command outputted to a mobile equipment part of the mobile station, or by disabling network operation functions, such as authentication algorithms, in the SIM, or by not sendind a specific acknowledgement to the network.
