Continuous supply of services defined as recurrent contracted services with periodic payments; natural resource grants treated similarly. The concept of continuous supply of services denotes services provided or agreed to be provided continuously or recurrently under a contract for a period exceeding three months with periodic payment obligations, and may include additional categories by government notification. Government allocation of natural resources to a successful bidder for right-to-use over time is treated as continuous supply where payments are structured either as an upfront amount or deferred periodic instalments, bringing such grants within the continuous-supply framework and any conditions set by notification.
