Frequently Asked Questions

First Interstate BancSystem, Inc. is a financial holding company headquartered in Billings, Montana. It is the parent company of First Interstate Bank, a community bank offering a full range of online, mobile, and other banking and financial services. When CMYF and IIB convert to First Interstate Bank in early June, you will have access to nearly 150 banking offices across Idaho, Montana, Oregon, South Dakota, Washington, and Wyoming.

First Interstate’s course was set by its founder, Homer Scott, Sr., who believed that people and organizations are not known by what they say, but by what they do. From the time Mr. Scott purchased his first bank in 1968, through their growth over five decades, the First Interstate family has always adhered to a strong set of guiding principles and values.

Established in 1968, what is now First Interstate Bank was originally a family of community banks operating under separate names. We started using the First Interstate Bank name in 1984 as part of a franchise agreement with First Interstate Bancorp, headquartered in California. In 1996, Wells Fargo acquired First Interstate Bancorp, but not this bank. Instead, we obtained an exclusive license to use the “First Interstate” name and logo and created the First Interstate BancSystem, Inc. holding company.

For now, it is business as usual at CMYF and IIB. You may continue your normal banking activities with the same bank staff you’ve come to know and trust in the same communities where you live and work.

No, not at this time. CMYF and IIB clients will be able to conduct business at First Interstate branches beginning Monday, June 10, 2019.

There will be no immediate changes to your accounts, and no action on your part is necessary at this time. Over the coming weeks, you will receive mailings from First Interstate regarding the transition. You’ll also learn more about the benefits of being a First Interstate client.

The majority of CMYF and IIB account numbers will remain the same. A small number of account numbers have been identified as duplicate account numbers with another First Interstate Bank account; as such, we will need to change the account numbers on those few accounts. If your account is impacted in any way, we will contact you individually. If you do not hear from us about your account number it will remain the same.

Your transferred deposits are separately insured from any accounts you may already have at First Interstate for at least six months after the date of the merger (through October 8, 2019). This grace period gives you a chance to restructure your accounts, if necessary, to make sure you have 100% FDIC coverage. Time Deposits (CDs) transferred to First Interstate Bank are separately insured until the earliest maturity date after the end of the six-month grace period. Time Deposits (CDs) that mature during the six-month grace period and are renewed for the same term in the same dollar amount (either with or without accrued interest) continue to be separately insured until the first maturity date after the six-month grace period. If a Time Deposit (CD) matures during the six-month grace period and is renewed on any other basis, it is separately insured only until the end of the six-month grace period.

There will be no changes to your debit card at this time; please continue to use your CMYF or IIB debit card. You will receive a new First Interstate debit card prior to the conversion in early June, at which time you may begin using it.

The deposits and withdrawals that post automatically to your checking or savings account will continue to be processed in the same way after conversion. In rare cases of duplicate account numbers requiring an account number change, Social Security or other entities that process automatic deposits or withdrawals from an account may need to be notified. If needed, First Interstate will make the initial contact with these entities on your behalf.

The terms and conditions of your loan contract at CMYF or IIB will remain as stated after it transfers to First Interstate. First Interstate Bank may report ‘negative information’ to a nationwide consumer reporting agency. Examples of this type of information are: late payments, missed payments, or other defaults. There is no need for you to do anything with your loan; however, if you have questions about your loan, please contact your banker.
