Acting with or showing care and thought for the future.
"Those with responsibility to invest money for others should act with prudence, discretion, intelligence, and regard for the safety of capital as well as income." Judge Samuel Putnum 1830 
The prudent man rule, directs trustees "to observe how men of prudence, discretion and intelligence manage their own affairs, not in regard to speculation, but in regard to the permanent disposition of their funds, considering the probable income, as well as the probable safety of the capital to be invested.”
