Revenue
Our revenue is comprised primarily of interest income, service charges and fees, gains on the sale of loans and AFS securities, earnings on corporate owned life insurance policies, and other noninterest income. Other noninterest income is typically service and performance driven in nature and comprised primarily of investment and trust advisory fees. We recognize revenue, excluding interest income, in accordance with ASC 606, Revenue From Contracts with Customers. Revenue is recognized when our performance obligation has been satisfied according to our contractual obligation.
We record receivables when revenue is unpaid and collectability is reasonably assured. Accounts receivable balances primarily represent amounts due from customers for which revenue has been recognized. Accounts receivable balances are recorded in the consolidated balance sheets in accrued interest receivable and other assets. For the years ended December 31, 2024, 2023 and 2022, we satisfied our performance obligations pursuant to contracts with customers. As a result, we have not recorded any contract assets or liabilities. We estimate no returns or allowances for the years ended December 31, 2024, 2023 and 2022.
Our contracts with customers define our performance obligations with clearly established pricing which did not require us to allocate or disaggregate revenue by performance obligation. A summary of revenue recognized for each major category of contracts with customers, subject to ASC 606, is as follows for the years ended December 31: | | | | | | | | | | | | | | | | | |
| 2024 | | 2023 | | 2022 |
| Debit card income | $ | 4,151 | | | $ | 4,063 | | | $ | 3,783 | |
| Trust service fees | 3,438 | | | 3,110 | | | 2,622 | |
| Investment advisory fees | 603 | | | 447 | | | 383 | |
| Service charges and fees related to deposit accounts | 450 | | | 362 | | | 345 | |
A significant portion of our revenue consists of interest income which is not subject to the requirements set forth in ASC 606.
About Revenue Disclosures
Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.
Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
