In order for an investor to invest in a riskier project, he/she will expect to receive higher returns to compensate for the extra risk.

AAA bonds are less risky than BBB bonds, which in turn are less risky than CCC bonds. That is why AAA bonds yield a lower return than BBB bonds, and BBB bonds yield a lower return than CCC bonds.
