The Comptroller's examiners, on October 31, 1919, consisted of a field force of 128 national bank examiners and as many assistants, who were under the immediate supervision of twelve chief examiners located in the twelve federal reserve districts, the number in each district varying with the number and size of the banks. Each district is subdivided, and an examiner is assigned to each subdivision and operates under the chief examiner. The chief examiner, whose headquarters are at the federal reserve city, acts under the general supervision of the Comptroller. Each examiner is assigned about seventy banks for examination at least twice a year, and is furnished an assistant in connection with the examinations of the larger banks. The assistant examiners are attached to the office of the chief examiner of the respective districts and are subject to his instructions.
The examiners send their original reports, together with data concerning credit, reconcilement, and other matters taken up during the examination, to the office of the chief examiner, where the typewritten reports are prepared, forwarded to the examiner for his signature, and then transmitted to the Comptroller's office. The credit data are tabulated in the chief examiner's office. The chief examiner also makes the necessary reconcilements of accounts with other banks. A copy of each report of examination is furnished to the federal reserve bank and to the bank examined. Wherever state and national banks are operated in the same building, or are closely affiliated, the state and national bank examiners arrange, if possible, for simultaneous examinations, and if conditions warrant, they discuss together loans and other matters.
