(Reuters) - Italian car maker Fiat said on Tuesday the merger with its U.S. unit Chrysler will be effective as of Oct. 12 after all conditions for the tie-up to go through were met.

Fiat said no creditors had opposed the merger and the amount of money to be paid to shareholders that chose to sell their shares had not exceeded a 500-million euro cap set by the company.

Shares in the new holding Fiat Chrysler Automobiles will start trading on the New York Stock Exchange on Oct. 13, Fiat said in a statement.
