Hello there!
Your question asks which of the statements does not occur when making a capital structure decision.
Answer: Deciding what assets to purchase
The reason why "Deciding what assets to purchase" is the correct answer because this is something that someone can't make an decision on when making capital structure decisions.
Capital structure is a way a business/company/corporation finances their assets with debt, equity, or securities that they have.
The capital structure would be depended on their liabilities.
All in all Capital structure is the financial calculations of a business/company's debt, equity, and securities. They can't make a decision on what assets to purchase, due to the fact that they're financing what they already have, without any decision on what assets they should get.
I hope this helps!
