  • EU and Malta Securitisation Market

    Following the US subprime crisis that began in 2007, the notion of securitisation has suffered from bad press that tainted its reputation. However, securitisation is still considered as an essential component to continued economic recovery and for well-functioning financial markets.

  • DOJ Makes the Pilot Program Permanent and Announces FCPA Corporate Enforcement Policy

    The US Department of Justice ("DOJ") had announced a pilot program [1] ("Pilot Program") on April 5, 2016, which created new mitigation opportunities for companies that (i) voluntarily self-disclosed, (ii) cooperated fully, and (iii) took timely and appropriate remedial actions in FCPA matters that fell within the Fraud Section's mandate. The Pilot Program was to remain in effect for 1 year, starting from the day of its announcement. On March 10, 2017, the Acting Assistant Attorney General, Kenneth A. Blanco, announced in a speech that the Pilot Program would continue in full force until the DOJ reached a final decision on whether to extend it, and what revisions, if any, should be made to it. [2] The evaluation period of the Pilot Program ended on November 29, 2017, when Deputy Attorney General Rod Rosenstein announced the new FCPA Enforcement Policy ("Policy"), which effectively makes the Pilot Program permanent with some revisions. According to Deputy Attorney General Rosenstein, the FCPA Unit received 30 voluntary disclosures during the time period that the Pilot Program was in force, as opposed to 18 voluntary disclosures that were received during the previous 18-month period. The Policy has been incorporated into the United States Attorneys' Manual in order to "be readily understood and easily applied by busy prosecutors" as opposed to being promulgated in memorandum format.

  • Crowdfunding - The Path towards a regulatory Framework

      The importance and feasibility of crowdfunding platforms is increasing in stature and importance for current and future the entrepreneurs. Malta has recently acceded to the rising trend by creating its first crowdfunding platform, ZAAR, a reward-based crowdfunding platform who has recently been awarded with the first prize in its section at the National Enterprise Support Awards 2016 also as well as being one of the local projects that have represented Malta at the European Enterprise Promotion Awards 2016, held in Slovakia. Nonetheless start-ups based in Malta with global aspirations often rely on international platforms. An increase in interest has emerged amongst the art and culture community as well in social entrepreneurship projects. Crowdfunding in Malta is still at the early stages of development. Despite this, there are endless opportunities for local entrepreneurs and the local business community. Research has shown that through international crowdfunding platforms, monies have been raised for projects in the field of gaming consoles, apps and software as well as for artistic projects.  Testimony to this is a new game design studio in Malta, that launched its first game, Politicks, raised financing through the crowdfunding platform Indiegogo.
