NEW YORK, April 19 (Reuters) - The International Monetary Fund said it has not endorsed a recent bond issuance from El Salvador that involves a larger payout to investors if a program between the government and the fund is not reached in 18 months or the country fails to earn multiple credit rating upgrades.

"We were not consulted and we haven't endorsed that operation, that is an operation between the country and the private sector," the IMF's director for the Western Hemisphere, Rodrigo Valdes, said on Friday in a press conference.

Valdes did not respond whether the fund expects more issuances to include similar wording.

He said conversations with El Salvador continue with the goal of a fund-supported program.
