Zasinthiranso kuchokera pamizu yake pamagetsi ndi chitetezo chamoto kuti athane ndi chitetezo chachikulu, monga zinthu zowopsa, madzi, chitetezo cha chakudya, kuyesa magwiridwe antchito, chitetezo ndi kutsatira malamulo komanso kusamalira zachilengedwe.

Mu 2012, UL idasintha kuchokera ku kampani yopanda phindu kukhala kampani yopanga phindu.
