The right of inspection is limited to a stockholder, or member, or group of stockholders or members, who hold of record voting shares having a cost of not less than one hundred thousand dollars ($100,000), or who hold of record voting shares constituting not less than 1 percent of the outstanding voting shares, provided in either case, the stockholder, member, or group of stockholders or members, have been holders of record of the voting shares for at least six months before making the written demand. The right of inspection created by this subdivision shall extend to the records of each subsidiary of an association subject to this subdivision and includes the right to make extracts.
(b) Notwithstanding the right of inspection granted in subdivision (a), no stockholder, member, or group of stockholders or members, shall have the right to inspect or make extracts of any portion of any register, book, or minutes of an association containing any of the following:
1. (1) A list of depositors in or borrowers from the association.
2. (2) The addresses of depositors or borrowers from the association.
3. (3) Individual deposit or loan balances or records. “Records” for the purposes of this paragraph means confidential facts pertaining to personal financial information about an individual, including, but not limited to, an individual’s credit file and any loan application.
4. (4) Any data from which any of the information described in paragraphs (1) to (3), inclusive, could be reasonably constructed.
(c) Each association director shall have the right at any reasonable time to inspect all books, records, documents of every kind, and the physical properties of that association. The inspection may be made in person or by agent or attorney, and the right of inspection includes the right to make extracts. In the case of foreign associations the right of inspection extends only to books, records, documents, and property located in this state.
(d) Savings accountholders who are not stockholders, members, or directors of an association shall have no right of inspection under this section.
