+# Periodic_payment
+
+## Periodic Payment allows some account to execute periodic release of funds after a period and number of rounds
+
+This allows TMPL_RCV to withdraw TMPL_AMT every
+
+TMPL_PERIOD rounds for TMPL_DUR after every multiple
+of TMPL_PERIOD.
+
+After TMPL_TIMEOUT, all remaining funds in the escrow
+are available to TMPL_RCV.
+
