DUBAI, Nov 9 (Reuters) - Jarir Marketing , one of Saudi Arabia's largest retailers by market value, said on Wednesday it was too early to judge the impact on its financials of Egypt's decision to float its currency.

* Impact will depend on exchange rate between Saudi Riyal and Egyptian Pound as on Dec. 31, which is "difficult to predict reliably at present", Jarir said in a bourse filing.

* If exchange rate is 1 riyal/4.5 pounds, impact estimated at 64 million riyals ($17.1 million).

* Jarir operates in Egypt through wholly-owned subsidiary Jarir Egypt Financial Leasing Co.

* Egypt's central bank abandoned the pound's peg of 8.8 to the dollar last Thursday, allowing the currency to float freely, in an effort to attract inflows of capital and crush a booming black market in dollars. ($1 = 3.7490 riyals)
