To pay for college, you have just taken out a $\$ 1,000$ government loan that makes you pay $\$ 126$ per year for 25 years. However, you dont have to start making these payments until you graduate from college two years from now. Why is the yield to maturity necessarily less than $12 \%$ (this is the yield to maturity on a normal $\$ 1,000$ fixed-payment loan in which you pay $\$ 126$ per year for $25 \text { years }) ?$
