Equity Components in Limited Companies Steps:

• Identify equity as shareholders' funds including share capital, reserves, and retained earnings.
• Review typical balance sheet items: 1 likely non-equity (e.g., liability like loans), 2-4 as equity (e.g., capital, reserves).
• Eliminate options listing multiple non-equity items if only one is invalid.
• Select option isolating the single non-equity item.

Why B is correct:

• Equity excludes liabilities; B identifies only item 1 (e.g., long-term debt) as non-equity per IFRS/GAAP definitions.

Why the others are wrong:

• A overstates by including 3 and 4, which are equity reserves.
• C wrongly excludes 2 (share premium, an equity component).
• D misidentifies 2 as the sole non-equity when it's actually part of share capital.
