Total Shareholder Return Vs Peer Group [Text Block] | The executive compensation actually paid differs from the compensation provided in the Summary Compensation Table due solely to changes in the value of RPSs and NQSOs between the grant date and the end of each fiscal year or vesting date. The change in the value of the NQSOs and RPSs is based on TSR excluding dividends as dividends are not paid on NQSOs or RPSs prior to vesting. | |||
Tabular List [Table Text Block] | As described in the Compensation Discussion and Analysis, the financial performance measures used to determine executive compensation levels include return on average equity, return on average assets, diluted earnings per share, levels of non-performing assets, and the efficiency ratio (operating expenses as a percentage of total revenues). The banking industry’s financial results and performance measures are heavily influenced by economic cycles and changing interest rates. Westamerica Bancorporation management applies long-term strategies and business practices to consistently maintain a conservative credit risk position and control operating expenses with the objective of generating financial results with less volatility relative to peers.
