The central government accomplished this reorganization by promising the former "daimyōs" a generous stipend, absorbing the domain's debts, and promising to convert the domain currency ("hansatsu") to the new national currency at face value. The central treasury proved unable to support such generosity, so in 1874, the ex-daimyo stipend was transformed into government bonds with a face value equivalent to five years' worth of stipends, and paying five percent interest per year. Samurai serving former "daimyōs" also received tradable government bonds of former salary dependent value. The owners of the bonds received interest until the bonds were reimbursed, which was decided by annual lottery. In 30 years, all bonds for samurais were reimbursed.
