Noncontrolling interest, description |  |  |  |  | We agreed to dilute our ownership percentage in FreshRealm, as an injection of significant working capital would reduce the immediate need of Calavo to provide operating funds to FreshRealm and would also serve to preserve the value of our investment. As a result of the admission of Impermanence, Calavo's ownership was reduced from 71.1% to 50.8%. Even though Calavo controlled greater than 50% of the outstanding units of FreshRealm, the minority/non-Calavo unit-holders held substantive participating rights. These rights existed primarily in two forms: (1) two out of a total of four board of director seats and (2) a provision in the Agreement that states that for situations for which the approval of the Members, as defined, is required by the Agreement, the Members shall act by Super-Majority Vote. As such, Calavo cannot control FreshRealm through its two board of director seats, nor its 50.8% ownership. Based on the foregoing, we deconsolidated FreshRealm in May 2014. |  |  |  |
