Explanation : All else held constant, in a period of declining costs the ending
inventory would be higher under weighted average and cost of goods
sold (COGS) will be lower (compared to FIFO) resulting in higher net
income and retained earnings. There will be no impact on the debt
level, current or long-term. Therefore the debt-to-equity ratio (Total
debt ÷ Total shareholder’s equity) will decrease due to the increase in
retained earnings (and higher shareholders’ equity).
