N.Y. Banking Law § 585
For the purpose of discovering violations of this article or securing information lawfully required by him or her hereunder, the superintendent may at any time, and as often as he or she may determine, either personally or by a person duly designated by him or her, investigate the business and examine the books, accounts, records, and files used therein of every licensee hereunder. For that purpose the superintendent and his or her duly designated representative shall have free access to the offices and place of business, books, accounts, papers, records, files, safes and vaults of all such licensees. The superintendent and any person duly designated by him or her shall have authority to require the attendance of and to examine under oath all persons whose testimony he or she may require relative to such business. The expenses incurred in making any examination pursuant to this section shall be assessed against and paid by the licensee so examined, except that traveling and subsistence expenses so incurred shall be charged against and paid by licensees in such proportions as the superintendent shall deem just and reasonable, and such proportionate charges shall be added to the assessment of the other expenses incurred upon each examination. Upon written notice by the superintendent of the total amount of such assessment, the licensee shall become liable for and shall pay such assessment to the superintendent. If, upon review, the superintendent shall determine that the fees or service charges set by the licensee are unreasonable, he or she shall direct the licensee to make adjustments in said fees and service charges in accordance with his or her findings, which shall set forth a detailed factual basis and reasoning supporting such finding.
