A maona (Arabic: معونة ma‘ūnah; lit. 'help'; Arabic: معاونة mu‘āwanah; lit. 'mutual help') also as mahona (pl. mahone) or societas comperarum was a medieval Italian association of investors formed to manage the purchased shares (loca or partes) of the revenue due to the relevant city-state through tax farming. The shares were individually sold to wealthy merchants who would band together to make collection easier.
