Provision for Loan and Lease Losses [Abstract]

Allowance for Loan Losses

Allowance for Loan Losses

The Company’s ALLL covers estimated credit losses on individually evaluated loans that are determined to be impaired as well as estimated probable incurred losses inherent in the remainder of the loan portfolio. The ALLL is prepared using the information provided by the Company’s credit review process together with data from peer institutions and economic information gathered from published sources.

The loan portfolio is segmented into groups of loans with similar risk characteristics. Each segment possesses varying degrees of risk based on, among other things, the type of loan, the type of collateral and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. An estimated loss rate calculated using the Company’s historical loss rates adjusted for current portfolio trends, economic conditions, and other relevant internal and external factors, is applied to each group’s aggregate loan balances.

The Company’s base ALLL factors are determined by management using the Bank’s annualized actual trailing charge-off data over a full credit cycle with an approximate average loss emergence period of 1 year to 1.6 years. Potential adjustments to those base factors are made for relevant internal and external factors. Those factors may include:

• Changes in lending policies and procedures, including underwriting standards and collection, charge-offs and recovery practices;

• Changes in the nature and volume of the loan portfolio, including new types of lending;

• Changes in the experience, ability, and depth of lending management and other relevant staff that may have an impact on our loan portfolio;

• Changes in the volume and severity of adversely classified or graded loans;

• Changes in the quality of our loan review system and the management oversight;

• The existence and effect of any concentrations of credit and changes in the level of such concentrations;

• Changes in national, regional and local economic conditions, including trends in real estate values and the interest rate environment;

• Changes in the value of the underlying collateral for collateral-dependent loans; and

• The effect of external factors, such as competition, legal developments and regulatory requirements on the level of estimated credit losses in our current loan portfolio

For loans risk graded as watch or worse, progressively higher potential loss factors are applied based on migration analysis of risk grading and net charge-offs.

The following tables summarize the allocation of the ALLL as well as the activity in the ALLL attributed to various segments in the loan portfolio as of and for the periods indicated:
