Disclosure Variable Interest Entities Schedule Of Equity Method Investments [Abstract] |
Variable Interest Entities | Regions is involved in various entities that are considered to be VIEs, as defined by authoritative accounting literature. Generally, a VIE is a corporation, partnership, trust or other legal structure that either does not have equity investors with substantive voting rights or has equity investors that do not provide sufficient financial resources for the entity to support its activities. The following discusses the VIEs in which Regions has a significant interest. AFFORDABLE HOUSING TAX CREDIT INVESTMENTS Regions periodically invests in various limited partnerships that sponsor affordable housing projects, which are funded through a combination of debt and equity. These partnerships meet the definition of a VIE. Regions uses the proportional amortization method to account for these investments. Due to the nature of the management activities of the general partner, Regions is not the primary beneficiary of these partnerships. See Note 1 for additional details. Additionally, Regions has loans or letters of credit commitments with certain limited partnerships. The funded portion of the loans and letters of credit are classified as commercial and industrial loans or investor real estate loans as applicable in Note 4. A summary of Regions’ affordable housing tax credit investments and related loans and letters of credit, representing Regions’ maximum exposure to loss as of December 31 is as follows:
| 2022 |  | 2021
| (In millions)
Affordable housing tax credit investments included in other assets | $ | 1,238 |  |  | $ | 1,045 |
Unfunded affordable housing tax credit commitments included in other liabilities | 511 |  |  | 348 |
Loans and letters of credit commitments | 598 |  |  | 410 |
Funded portion of loans and letters of credit commitments | 282 |  |  | 148 |
| 2022 |  | 2021 |  | 2020
| (In millions)
Tax credits and other tax benefits recognized | $ | 180 |  |  | $ | 165 |  |  | $ | 164 |
Tax credit amortization expense included in provision for income taxes | 149 |  |  | 139 |  |  | 133 |
In addition to the investments discussed above, Regions also syndicates affordable housing investments. In these syndication transactions, Regions creates affordable housing funds in which a subsidiary is the general partner or managing member and sells limited partnership interests to third parties. Regions' general partner or managing member interest represents an insignificant interest in the affordable housing fund. The affordable housing funds meet the definition of a VIE. As Regions is not the primary beneficiary and does not have a significant interest, these investments are not consolidated. At December 31, 2022 and 2021, the value of Regions’ general partnership interest in affordable housing investments was immaterial.
