"Farm Bureau is an independent, non-governmental, voluntary organization of farm and ranch families united for the purpose of analyzing their problems, and formulating action to achieve educational improvement, economic opportunity, and social advancement and thereby, to promote the national well-being. Farm Bureau is local, county, state, national, and international in its scope and influence, and is non-partisan, non-sectarian, and non-secret in character. Farm Bureau is the voice of agricultural producers at all levels. Farm Bureau in Oklahoma was originally organized in 1942 as an independent farm organization. It was chartered under the laws of the state of Oklahoma on February 3, 1942, under the Cooperative Marketing Association Act. The Articles of Incorporation of the Oklahoma Farm Bureau were amended on March 4, 1962, and again on September 2, 1970, to reflect changes in the Oklahoma Statutes (which went into effect in February of 1968) relating to non-profit corporations, under Title 18, Section 858, pertaining to a provision in the IRS code for businesses operating as "501" (C)(5) corporations. OFB affiliated with the American Farm Bureau Federation (AFBF) on March 1, 1942, when the first cooperative agreement was signed between the two organizations."
