UPDATE 1-IMF says completes 403.3 tonnes gold sales program

(Adds details on gold sales)

WASHINGTON Dec 21 (Reuters) - The International Monetary Fund said on Tuesday it had concluded the sale of 403.3 tonnes of gold under a program approved in September 2009 to help boost its lending resources.

All gold sales were at market prices, including direct sales to official holders, the IMF said in a statement.

The gold sales amounted to one-eighth of the IMF's total gold reserves. The fund sold 200 tonnes to India's central bank last year.

Other buyers have included Bangladesh, Sri Lanka and Mauritius.

The IMF said on Nov. 29 it told 19.5 tonnes of gold in October, but it has not yet provided details of sales in November or December.
