Final answer:
Under GAAP, only the amount actually refinanced can be excluded from current liabilities and reclassified as long-term debt.
Step-by-step explanation:
According to Generally Accepted Accounting Principles (GAAP), the maximum amount that can be excluded from current liabilities through refinancing is the amount that is actually refinanced. In other words, if a company has a current liability that it is able to refinance, the company can reclassify that liability as a long-term debt or non-current liability up to the amount of the new financing obtained as long as it meets certain criteria before the balance sheet date, such as an actual financing agreement.
