Regulatory Capital
 
Under current capital regulations, the Bank is required to comply with
four
separate capital adequacy standards. As of
December 31, 2018,
the Bank continued to be categorized as “well-capitalized” under the prompt corrective action regulations and continued to exceed all regulatory capital requirements. In
2016,
a Capital Conservation Buffer (“CCB”) requirement became effective for banks. The CCB is designed to establish a capital range above minimum capital requirements and impose constraints on dividends, share buybacks and discretionary bonus payments when capital levels fall below prescribed levels. The minimum CCB in
2018
was
1.875%
and increases
0.625%
annually through
2019
to
2.5%.
The CCB for the Bank at
December 31, 2018
and
2017
was
5.70%
and
6.31%,
respectively.
