premise: Sept 4 (Reuters) - J.P. Morgan Asset Management, a unit of JPMorgan Chase & Co, said it appointed Pietro Grassano the new country head for France. Based in Paris, Grassano started in his new role on Sept. 1, J.P. Morgan Asset Management said in a statement. Grassano, who has been with the company since 2002, was previously the head of sales for Italy, covering wholesale and retail distribution. He has earlier worked at BNP Paribas Asset Management.
hypothesis: Pietro Grassano was once the country head for France.
reason: "J.P. Morgan Asset Management, a unit of JPMorgan Chase & Co, said it appointed Pietro Grassano the new country head for France." I think it was difficult because I worded it past tense, "He was ONCE the country head", but I believe that statement is true because it is past Sept 1 when he was appointed.
