The last row of sensitivity has a value 60.4644 because when wacc=0.1283 and growth=0.1183, growth < wacc so it's valid (though the growth rate is very close to wacc, making the terminal value very large).\n\nLet me double-check the logic for the sensitivity grid - the last entry in sens_growth is 0.1183, and when paired with wacc=0.1283, 0.1183 < 0.1283 so it's valid. But when paired with lower wacc values like 0.0883, 0.0983, 0.1083, 0.1183, the growth >= wacc so those are null.\n\nThis looks correct.

Let me check if there's a rounding issue...\n\nActually, I think the issue is that I'm computing with full precision in the code. Let me trace through more carefully.\n\nWait, I see the issue. The code rounds the money values to 2 decimals for the main output, but for sensitivity it uses the raw per_share value and rounds to 4 decimals. But the sensitivity calculation uses the full precision values.\n\nLet me verify the sensitivity calculation in the code more carefully. The `compute_dcf` function returns full precision values, and then we round per_share to 4 decimals.\n\nLet me recalculate:\n- PV FCF = 100/1.08 + 110/1.08^2 = 92.5925925925926 + 94.30727023319616 = 186.89986282578876\n- TV = 110 * 1.01 / 0.07 = 1587.142857142857\n- PV TV = 1587.142857142857 / 1.1664 = 1360.722787661059\n- EV = 186.89986282578876 + 1360.722787661059 = 1547.6226504868478\n- Equity = 1547.6226504868478 - 50 = 1497.6226504868478\n- Per share = 149.76226504868478 \u2192 149.7623 when rounded to 4 decimals\n\nBut the output shows 149.7619. That's a difference of 0.0004. Let me check if there's something wrong with my understanding...\n\nActually wait, I need to check the terminal value calculation again. The formula is fcf_N * (1 + g) / (wacc - g).\n\nfcf_N = 110\ng = 0.01\nwacc = 0.08\n\nTV = 110 * 1.01 / (0.08 - 0.01) = 111.1 / 0.07 = 1587.142857142857\n\nThat's correct.\n\nLet me check if the code is doing something different...\n\nActually, I think I need to trace through the actual code execution.
