[Transaction fees] Rate lock [Fee exemptions apply.] 
Rate lock protects you against interest rate movements by locking the current fixed interest rate before drawdown for up to 90 days. Rate lock will also allow for the 'best of rate' option. If the current rate is lower at drawdown than the rate locked, the lower interest rate will apply. Rate Lock is available on new funds for new Fixed Rate sub accounts and new Interest in Advance Fixed Rate sub accounts.
