(a) Deferred delivery. Use the clause at 252.227-7026 , Deferred Delivery of Technical Data or Computer Software, when it is in the Government's interests to defer the delivery of technical data. The clause permits the contracting officer to require the delivery of technical data identified as “deferred delivery” data at any time until two years after acceptance by the Government of all items (other than technical data or computer software) under the contract or contract termination, whichever is later. The obligation of subcontractors or suppliers to deliver such technical data expires two years after the date the prime contractor accepts the last item from the subcontractor or supplier for use in the performance of the contract. The contract must specify which technical data is subject to deferred delivery. The contracting officer shall notify the contractor sufficiently in advance of the desired delivery date for such data to permit timely delivery.
(b) Deferred ordering. Use the clause at 252.227-7027 , Deferred Ordering of Technical Data or Computer Software, when a firm requirement for a particular data item(s) has not been established prior to contract award but there is a potential need for the data. Under this clause, the contracting officer may order any data that has been generated in the performance of the contract or any subcontract thereunder at any time until three years after acceptance of all items (other than technical data or computer software) under the contract or contract termination, whichever is later. The obligation of subcontractors to deliver such data expires three years after the date the contractor accepts the last item under the subcontract. When the data are ordered, the delivery dates shall be negotiated and the contractor compensated only for converting the data into the prescribed form, reproduction costs, and delivery costs.
