Schedule of Compliance with Regulatory Capital Requirements under Banking Regulations

The following table presents Summit's, as well as Summit Community's, actual and required minimum capital amounts and ratios as of September 30, 2018 and December 31, 2017 under the Basel III Capital Rules.  The minimum required capital levels presented below reflect the minimum required capital levels (inclusive of the full capital conservation buffers) that will be effective as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in.  Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules.
