Section 560. Investigations and examinations

1. The superintendent shall
  have the power to make such investigations as he shall deem necessary to
  determine whether any licensee or any other person has violated  any  of
  the  provisions  of  this article, or whether any licensee has conducted
  himself in such manner as would justify the revocation of  his  license,
  and  to  the extent necessary therefor, he may require the attendance of
  and examine any person under oath, and shall have the  power  to  compel
  the production of all relevant books, records, accounts, and documents.
    2.  The  superintendent shall have the power to make such examinations
  of the books, records, accounts and documents used in  the  business  of
  any  licensee  as  he shall deem necessary to determine whether any such
  licensee has violated any of the provisions of this article.
    3. The  expenses  incurred  in  making  any  examination  pursuant  to
  subdivision  two  of  this  section five hundred sixty 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.
    4.   All   reports   of   examinations  and  investigations,  and  all
  correspondence  and  memoranda  concerning  or  arising  out   of   such
  examinations or investigations, including any duly authenticated copy or
  copies  thereof  in  the  possession  of  any  licensee  or  the banking
  department, shall be confidential communications, shall not  be  subject
  to  subpoena and shall not be made public unless, in the judgment of the
  superintendent, the ends of justice and the  public  advantage  will  be
  subserved  by  the publication thereof, in which event he may publish or
  authorize the publication of a copy of any such report or other material
  referred to in this subdivision four,  or  any  part  thereof,  in  such
  manner as he may deem proper.
