That evening, she went back to the GitHub repo. The fin_hermit_99 account had no real name, no email, just a single bio line: "I failed corporate finance in 2003. Took me ten years to really understand it. Leaving these notes so you don't have to."
But there didn't need to be. The solutions weren't the point. The understanding was.
She had tried. She really had. But the difference between Proposition I (with taxes) and Proposition II (the cost of equity) had dissolved into a blur of algebraic spaghetti. Her problem set was due in six hours. The "Solutions" section in the back of the book only gave final answers, not the path to get there. Principles Of Corporate Finance 14th Edition Solutions
Then she found it.
Problem 17.6a: VL = VU + Tc*D Wait — did you forget that debt is perpetual here? If interest is tax-deductible at 21%, the tax shield is 0.21 * $10M debt = $2.1M. So VL = $50M + $2.1M = $52.1M. (Book answer says 52.1 — good. But only if no growth. See p. 462.) She blinked. The voice in the note was patient, almost like a tutor sitting next to her. It didn't just give the answer—it caught the mistake she would have made .
She worked through the next three problems using the notes, and for the first time all night, the logic clicked. Debt didn't just "matter" or "not matter"—it was a balancing act of tax codes, bankruptcy costs, and investor behavior. The numbers weren't magic; they were consequences. Priya clicked
By 5:00 AM, her problem set was done. She didn't copy the answers—she re-did each one, checking her work against the hermit's commentary. She even found a small typo in Problem 17.12b (the hermit had used 34% instead of 21% for the old tax rate) and left a polite correction in a GitHub issue.
The page loaded in raw markdown. It wasn't official. It was better. Each problem was annotated with not just the numeric solution, but a short, handwritten-style note in ASCII:
There was no official "Principles Of Corporate Finance 14th Edition Solutions" PDF that ever explained things that way. Took me ten years to really understand it
A plain, gray GitHub repository. No stars, no forks, just a single file: brealey_myers_allen_solutions_ch17_20.md . The owner's name was fin_hermit_99 . Last commit: three years ago.
She typed anyway: "Principles Of Corporate Finance 14th Edition Solutions" into a search engine.
