The light line is your bond's pre-tax value. The three Net lines are what you'd actually pocket cashing out at each point - after federal tax, and after the early-redemption penalty while the bond is under 5 years old (which is why Net (Hold) sits lower through year 5 and steps up the moment it turns 5, and why all three meet at today's redeem value). Net (Hold) keeps this bond; Net (Rebuy I‑Bond) and Net (Switch to TIPS) redeem today and reinvest. Projection endpoints match the strategy table below.
