intrinsic value - for equity only???

The CFAI materials discuss equity valuation along with instrinsic value. However, when the materials discuss fixed income valuation, they don’t mention intrinsic value. However when you value a fixed income security you are determining its intrinsic value. Plenty of other materials use the phrase intrinsic value with fixed income valuation. Anyone know why intrinsic value is limited to equity valuation in the CFAI materials?
