The Millennium Challenge Corp.’s board on Tuesday selected Lesotho to begin developing a proposal for the country’s second compact, and decided not to move forward on proposals with Sierra Leone and Benin after they failed to meet the benchmark indicator for “control of corruption.

Although Sierra Leone and Benin both cleared that hurdle last year — and MCC found no evidence to suggest their regression in 2013 was the result of any changes to their policy environments — the performance was likely the result of “statistical noise” or variation in measuring the various indicators of corruption that MCC considers.
