that any such regulatory authority may, among other things, require the writing down of assets or increases in the allowance for loan losses; the ability to manage loan delinquency rates; competitive pressures among financial services companies;

System, the Federal Deposit Insurance Corporation, the Washington State Department of Financial Institutions, Division of Banks, or other regulatory authorities, including the possibility that any such regulatory authority may, among other things,
require restitution or institute an informal or formal enforcement action which could require an increase in reserves for loan losses, write-downs of assets or changes in regulatory capital position, or affect the ability to borrow funds, or
maintain or increase deposits, or impose additional requirements and restrictions, any of which could adversely affect liquidity and earnings; the availability of resources to address changes in laws, rules, or regulations or to respond to
regulatory actions; adverse changes in the securities markets; the inability of key third-party providers to perform their obligations; changes in accounting principles, policies or guidelines, including additional guidance and interpretation on
