Mohammad Barkindo said to reach the proposed cut of 1.2 million barrels per day, the effective reduction for member countries was 3.02 percent. That is higher than the initially discussed 2.5 percent as OPEC seeks to accommodate Iran, Libya and Venezuela, which are exempt from any requirement to cut. Sources had initially said OPEC would not publish individual quotas.
