As a result of the adoption of the current expected credit loss (“CECL”) accounting standard, the Company adjusted the January 1, 2020 ACL balances within each loan segment to reflect the changes from the incurred loss model to the current expected credit loss model which resulted in increases and decreases in each loan segment based on, among other factors, quantitative and qualitative assumptions and the economic forecast to estimate the provision for credit losses over the expected life of the loans. During the year ended December 31, 2021, the ACL increased primarily as a result of the $18,056,000 provision for credit losses recorded as a result of the Alta acquisition. During the year ended December 31, 2020, primarily as a result of the COVID-19 pandemic, there was a significant increase in the overall ACL and increases and decreases within certain loan segments. In addition, during 2020 the acquisition of SBAZ resulted in a $4,794,000 increase in the ACL due to the provision for credit losses recorded subsequent to the acquisition date. The COVID-19 pandemic significantly adjusted the economic forecast used in the ACL model including a significant increase in national and regional unemployment rates and a significant decrease in the gross domestic product (“GDP”).

The sizeable charge-offs in the other consumer loan segment is driven by deposit overdraft charge-offs which typically experience high charge-off rates and the amounts were comparable to historical trends. The other segments experience routine charge-offs and recoveries, with occasional large credit relationships charge-offs and recoveries that cause fluctuations from prior periods. During the year ended December 31, 2021, there have been no significant changes to the types of collateral securing collateral-dependent loans.

During the year ended December 31, 2021, the Company acquired loans through the Alta acquisition. Such loans were evaluated at acquisition date and it was determined there were PCD loans totaling $58,576,000 with an ACL of $371,000. There was also a premium associated with such loans of $840,000, which was attributable to changes in interest rates and other factors such as liquidity as of acquisition date.

During the year ended December 31, 2020, the Company acquired loans through the SBAZ acquisition. Such loans were evaluated at acquisition date and it was determined there were PCD loans totaling $3,401,000 with an ACL of $49,000. There was also a discount associated with such loans of $13,000, which was attributable to changes in interest rates and other factors such as liquidity as of acquisition date.

A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. The collateral on the loans is a significant portion of what secures the collateral-dependent loans and significant changes to the fair value of the collateral can impact the ACL. During 2021, there were no significant changes to collateral which secures the collateral-dependent loans, whether due to general deterioration or other reasons. The following table presents the amortized cost basis of collateral-dependent loans by collateral type:
