In the Fixed Capital Method, partner capital accounts solely record fixed contributions. Adjustments such as profit/loss shares, interest on capital, drawings, and interest on drawings are managed within the partners' current accounts, not their capital accounts. Consequently, Assertion (A) is valid because current accounts can show either a debit or credit balance depending on transactions. Reason (R) is invalid, however, as it incorrectly assigns all these adjustments to the capital accounts.
