In this regard, use bullets for the first two paragraphs and include the shares to be purchased in the offering, the percentage of those to be sold and the percentage of those to be outstanding. For example, the bullet on page 7 indicates a benefit plan that will issue options representing 10% of the shares sold in the offering. Page 9 is unclear if the 4.90% represents the same amount, i.e., is 10.0% of the shares sold the same as 4.9% of outstanding shares. In addition, clarify on page 9 if these shares will be purchased in the offering or purchased in open market transactions after the offering. 4. Revise to add a footnote to the "Percent of Shares Sold" column in the table appearing on page 10 and clarify why the bullets on page 7 have different percentages.

Footnote 4 states that the "Additional paid-in-capital" line item includes the value of shares issued to the charitable foundation; however, it appears that this value is included in a separate line item entitled "Contribution to charitable foundation" line item. Please revise or advise. Business Strategy, page 55 11. Revise the third bullet to indicate whether or not there are any plans, arrangements, and/or understandings to add branches and/or dispose of branches or make any acquisitions.
