A company's capital consists of 100 000 ordinary shares issued at $3 and paid to $2 per share.

On 1 September, a call of $1 was made on the ordinary shares. By 30 September, the call money received amounted to $90 000. No further payments were received, and on 31 October, the shares on which calls were outstanding were forfeited. On 15 November, the forfeited shares were reissued as paid to $3.00 for a payment of $2.50 per share. The appropriate cash amount from the reissue was received on 19 November. Costs of reissue amounted to $700. The company's constitution provided for any surplus on resale, after satisfaction of unpaid calls, accrued interest and costs, to be returned to the shareholders whose shares were forfeited.

What is the remaining balance of the forfeited share account that is refundable to shareholders? $4 500 $4 300 $4 200 $10 000
