PPPs are usually structured so that the Authority makes no payment to the PPP Company when the PPP contract expires at the end of its scheduled term. Termination payments are, however, envisaged upon contract expiry in certain circumstances. A typical case is that of new assets constructed at some stage during the life of the PPP contract as a result of an extraordinary event (this may involve a lump-sum termination payment from the Authority). Similarly, where PPP assets have a particularly long life compared to the term of the PPP contract, the payment of a residual asset value upon expiry may be contemplated.
