 The company was listed in January 2013 and is a closed end mutual fund with a lifespan of approximately 20 years.The energy sector of Trinidad and Tobago, which is the main driver of the economy and the major source of revenue for the country, is poorly represented on the TTSE, with only the minor oil company, Moraven Holdings (MOV) and National Enterprises (NEL) offering any access to the local energy market.The listing of TTNGL provided some opportunity to buy into the local energy market but significant companies such as Petroleum Company of Trinidad and Tobago (Petrotrin) and National Petroleum Marketing Company (NP) still remain entirely owned by the state.
