### Steps to reproduce

```
$V_0 = \underbrace{\frac{D_0(1 + g_1)}{r-g_1}\left[1-\left(\frac{1+g_1}{1+r}\right)^{a}\right]}_\text{Stage 1} + \underbrace{\frac{D_0(1+g_1)^a(1+g_2)}{(r-g_2)(1+r)^a}\left[1-\left(\frac{1+g_2}{1+r}\right)^{n}\right]}_\text{Stage_2} + \underbrace{\frac{D_0(1+g_1)^a(1+g_2)^{n-a}(1+g_3)}{(r-g_3)(1+r)^n}}_\text{Stage 3}$
