This chapter on the Singaporean leniency programme holds that various elements point to its effectiveness. The leniency programme guarantees immunity for a leniency applicant prior to an investigation, immunity could be obtained by the first leniency applicant once an investigation has started, and granting leniency to subsequent leniency applicants is at the discretion of the Singaporean enforcement agency, the Competition and Consumer Commission of Singapore (CCCS). Furthermore, leniency plus, whereby extra reduction can be obtained for revealing participation in another cartel, and the fast-track procedure, whereby extra reduction can be obtained for admitting to the fact, have been introduced as well. It is now also possible for a cartel to be exposed through a reward or whistle-blowing scheme, though this scheme is not available for persons active in the infringement. Because of these elements, the leniency programme has contributed to eight of the fifteen cartel infringement decisions. Some of these cases have led to record high fines. Another element worth mentioning is that some of the leniency applications were only submitted after active solicitation by the CCCS.

The concluding chapter argues that the Asian leniency programmes only converge on the core elements of a leniency programme. The core elements are the building blocks of a leniency programme. However, the composition of these blocks is often different. Some of the differences are subtle. Other differences make the respective leniency programme distinct from the others. Some of the distinctive elements are not necessarily part of the building blocks any more and thus give a unique character to the respective leniency programme. This chapter further claims that these differences can be explained by either the political economy of a country, experimentation due to prior negative enforcement results and a desire to achieve better enforcement results, or foreign influence. Since the result of experimentation cannot always be predicted, the authors estimate that further amendments will be made to the Asian leniency programmes.
