(2) on what date the decision was made to change the system of fully operational serviceability targets for the Army tank fleet from readiness in 24 hours to immediate availability; for what operational reasons; and if he will make a statement. 
§ Mr. Spellar
[holding answer 26 February 2001]: The decision to change the system of reporting equipment availability was taken in May last year. The change was made following the adoption of the Formation Readiness Cycle which places different units in the Army at different readiness states. Some of these states require equipment to be available immediately (ie capable of undertaking the task to which it has been allocated), while for others a much longer lead time will be acceptable.
The serviceability targets for the equipment types listed by the right hon. and learned Member, which reflect this change in the reporting system, are shown in the table.
