Whenever, in the judgment of the supervisor, the condition of any association renders it necessary or expedient to make an additional examination, or to devote any extraordinary attention to its affairs, the supervisor shall cause the work to be done at the expense of the association. A complete copy of the report of all examinations shall be furnished to the association examined. Every report of examination shall be presented to the board of directors at its next regular meeting, or at a special meeting called for the purpose, and noted in the minutes.
