It is the society's money where is the question of returning to some other or pocketing that amount if there is surplus amount conduct Independence day or Vinayaka Chaturthi etc., and use the surplus money for common benefit and enjoyment. Reduce maintenance so that everyone can enjoy it. It is not great management but exploitation if excess maintenance is being collected. The corpus fund is mainly for unforeseen events like an additional bore, getting water tanker during scarcity, building maintenance with periodical color wash etc. Because there are excess funds, by taxing too much from residents or because owners are obedient, trusted President, and obliging society, that should never be taken as lenience. Stand as an example for straightforwardness and good maintenance of society with honesty.
