Good afternoon . Can I be of service ?   I don't know . Can I purchase Treasury Certificates here at this counter ?   Yes , of course . We have Treasury Notes with two , three and five-year terms available .   Two years is fine , with a value of 1,000 RIB .   OK , could I take a look at some ID please , like a passport ?   Here you go . By the way , is it possible to cash them before the maturity comes up ?   No , I'm afraid that isn't possible . You must wait until maturity before you cash them .
