Note 8 Fair Value Measurements

Assets and liabilities measured at fair value on a recurring basis

The following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which those measurements are typically classified.

Investment securities available for sale and marketable equity securities—Fair value measurements are based on quoted prices in active markets when available; these measurements are classified within level 1 of the fair value hierarchy. These securities typically include U.S. Treasury securities and certain preferred stocks. If quoted prices in active markets are not available, fair values are estimated using quoted prices of securities with similar characteristics, quoted prices of identical securities in less active markets, discounted cash flow techniques, or matrix pricing models. These securities are generally classified within level 2 of the fair value hierarchy and include U.S. Government agency securities, U.S. Government agency and sponsored enterprise MBS, preferred stock investments for which level 1 valuations are not available, non-mortgage asset-backed securities, single family real estate-backed securities, private label residential MBS and CMOs, private label commercial MBS, collateralized loan obligations and state and municipal obligations. Pricing of these securities is generally primarily spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities.

The Company uses third-party pricing services in determining fair value measurements for investment securities. To obtain an understanding of the methodologies and assumptions used, management reviews written documentation provided by the pricing services, conducts interviews with valuation desk personnel and reviews model results and detailed assumptions used to value selected securities as considered necessary. Management has established a robust price challenge process that includes a review by the treasury front office of all prices provided on a quarterly basis. Any price evidencing significant unexpected quarter over quarter fluctuations or deviations from expectations is challenged. The Company has also established a quarterly process whereby prices provided by its primary pricing service are validated by obtaining a price from a second external source for most securities in the portfolio. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation source. The Company does not typically adjust the prices provided, other than through this established challenge process. The results of price challenges are subject to review by executive management. Any price discrepancies are resolved based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Derivative financial instruments—Fair values of interest rate derivatives are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include benchmark swap rates and benchmark forward yield curves. These fair value measurements are generally classified within level 2 of the fair value hierarchy.

Assets and liabilities measured at fair value on a non-recurring basis

Following is a description of the methodologies used to estimate the fair values of assets and liabilities that may be measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified:

Collateral dependent loans and OREO—The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral, which may be real estate, enterprise value or other business assets, less estimated costs to sell when repayment is expected to come from the sale of the collateral. The carrying value of OREO is initially measured based on the fair value of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral and OREO are typically based on third-party real estate appraisals which utilize market and income approaches to valuation incorporating both observable and unobservable inputs.

Fair value measurements related to collateral dependent loans and OREO are generally classified within level 3 of the fair value hierarchy.

The following table presents the net carrying value of assets classified within level 3 of the fair value hierarchy at the dates indicated, for which non-recurring changes in fair value were recorded during the period then ended (in thousands):

Income Tax Disclosure [Abstract]
Income Taxes	Note 5 Income Taxes The Company’s effective income tax rate was 26.1% and 26.9% for the three and nine months ended September 30, 2024 and 24.7% and 25.9% for the three and nine months ended September 30, 2023, respectively. The effective income tax rates differed from the statutory federal income tax rate of 21% for the three and nine months ended September 30, 2024 and 2023 primarily due to the impact of state income taxes and interest on certain unrecognized tax benefits, partially offset by the benefit of income not subject to federal tax.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Accounting Estimates	Accounting Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates. The most significant estimate impacting the Company's consolidated financial statements is the ACL.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2024 ASU No. 2023-02—Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures using the Proportional Amortization Method (A Consensus of the Emerging Issues Task Force). This ASU was issued to expand the use of the proportional amortization method of accounting for equity investments in tax credit programs beyond those in LIHTC programs. The ASU allows entities to elect the proportional amortization method, on a tax credit program by tax credit program basis, for all equity investments in tax credit programs meeting the eligibility criteria. The Company adopted this ASU in the first quarter of 2024. There was no impact upon adoption. Currently, all of the Company's equity investments in tax credit programs are in LIHTC programs already accounted for using the proportional amortization method. Accounting Pronouncements Not Yet Adopted ASU No. 2023-07—Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU augments reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment and contain other disclosure requirements. This ASU is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. This ASU is not expected to have an impact on the Company's consolidated financial position, results of operations and cash flows. Adoption will result in additional disclosures beginning with the Company's Annual Report on Form 10-K for the year ended December 31, 2024. ASU No. 2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires entities to provide additional disclosures, primarily related to the income tax rate reconciliation and income taxes paid. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions among others. This ASU is effective for the Company for fiscal years beginning after December 15, 2024. The adoption of this ASU is not expected to have an impact on the Company's consolidated financial position, results of operations and cash flows. Adoption will lead to revised disclosures about income taxes in the Company's financial statements.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 9 Commitments and Contingencies

The Company issues off-balance sheet financial instruments to meet the financing needs of its customers. These financial instruments include commitments to fund loans, unfunded commitments under existing lines of credit, and commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers, and are subject to the same credit policies used in underwriting loans. Collateral may be obtained based on the Company’s credit evaluation of the counterparty. The Company’s maximum exposure to credit loss is represented by the contractual amount of these commitments.

Commitments to fund loans

These are agreements to lend funds to customers as long as there is no violation of any condition established in the contract. Commitments to fund loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of these commitments are expected to expire without being funded and, therefore, the total commitment amounts do not necessarily represent future liquidity requirements.

Unfunded commitments under lines of credit

Unfunded commitments under lines of credit include commercial and commercial real estate lines of credit to existing customers, for many of which additional extensions of credit are subject to borrowing base requirements. Some of these commitments may mature without being fully funded, so may not necessarily represent future liquidity requirements.

Commercial and standby letters of credit

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Total lending related commitments outstanding at September 30, 2024 were as follows (in thousands):


Commitments to fund loans	$	100,769

Unfunded commitments under lines of credit	4,705,518
Commercial and standby letters of credit	150,351
	$	4,956,638

Legal Proceedings

The Company is involved in various legal actions arising in the normal course of business. In the opinion of management, based upon advice of legal counsel, the likelihood is remote that the adverse impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.

Financing Receivable Credit Quality Indicators

Credit quality information

Credit quality of loans held for investment is continuously monitored by dedicated residential credit risk management and commercial portfolio management functions. The Company also has a workout and recovery department that monitors the credit quality of criticized and classified loans and an independent internal credit review function.

Credit quality indicators for commercial loans

Factors that impact risk inherent in commercial portfolio segments include but are not limited to levels of economic activity or potential disruptions in economic activity, health of the national, regional and to a lesser extent global economy, interest rates, industry trends, demographic trends, inflationary trends, including particularly for commercial real estate loans the cost of insurance, patterns of and trends in customer behavior that influence demand for our borrowers' products and services, and commercial real estate values and related market dynamics. Particularly for the office sector, the evolving impact of hybrid and remote work on vacancies and valuations is a factor. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are one indicator of the likelihood that a borrower will default, are a key factor influencing the level and nature of ongoing monitoring of loans and may impact the estimation of the ACL. Internal risk ratings are updated on a continuous basis. Generally, relationships with balances in excess of defined thresholds, ranging from $2 million to $3 million, are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. The special mention rating is considered a transitional rating for loans exhibiting potential credit weaknesses that could result in deterioration of repayment prospects at some future date if not checked or corrected and that deserve management’s close attention. These borrowers may exhibit declining cash flows or revenues or increasing leverage. Loans with well-defined credit weaknesses that may result in a loss if the deficiencies are not corrected are assigned a risk rating of substandard. These borrowers may exhibit payment defaults, inadequate cash flows from current operations, operating losses, increasing balance sheet leverage, project cost overruns, unreasonable construction delays, exhausted interest reserves, declining collateral values, frequent overdrafts or past due real estate taxes. Loans with weaknesses so severe that collection in full is highly questionable or improbable, but because of certain reasonably specific pending factors have not been charged off, are assigned an internal risk rating of doubtful.

Credit quality indicators for residential loans

Management considers delinquency status to be the most meaningful indicator of the credit quality of residential loans, other than government insured residential loans. Delinquency status is updated at least monthly. LTV and FICO scores are also important indicators of credit quality for 1-4 single family residential loans other than government insured loans. FICO scores are generally updated semi-annually, and were most recently updated in the third quarter of 2024. LTVs are typically at origination since we do not routinely update residential appraisals. Substantially all of the government insured residential loans are government insured buyout loans, which the Company buys out of GNMA securitizations upon default. For these loans, traditional measures of credit quality are not particularly relevant considering the guaranteed nature of the loans and the underlying business model. Factors that impact risk inherent in the residential portfolio segment include national and regional economic conditions such as levels of unemployment, wages and interest rates, as well as residential property values.

Derivatives and Hedging Activities

Derivative Financial Instruments

Derivatives designated as hedging instruments

The Company has entered into interest rate derivatives designated as (i) cash flow hedges with the objective of limiting the variability of interest payment cash flows and (ii) fair value hedges designed to hedge changes in the fair value of outstanding fixed rate instruments caused by fluctuations in the benchmark interest rate. Changes in fair value of derivative instruments designated as cash flow hedges are reported in accumulated other comprehensive income. Changes in the fair value of derivative instruments designated as fair value hedges are recognized in earnings, as is the offsetting gain or loss on the hedged item.

The following table summarizes the Company's derivatives designated as hedging instruments as of the dates indicated (in thousands):


	September 30, 2024						December 31, 2023

During the three and nine months ended September 30, 2024 and 2023, no derivative positions designated as cash flow hedges were discontinued and none of the gains and losses reported in AOCI were reclassified into earnings as a result of the discontinuance of cash flow hedges or because of the early extinguishment of debt.

As of September 30, 2024, the amount of net gain expected to be reclassified from AOCI into earnings during the next twelve months was $8.8 million, based on the forward curve. See Note 7 to the consolidated financial statements for additional information about the reclassification adjustments from AOCI into earnings.

The Company enters into interest rate derivative contracts with certain of its commercial borrowers to enable those borrowers to manage their exposure to interest rate fluctuations. To mitigate interest rate risk associated with these derivative contracts, the Company enters into offsetting derivative contract positions with primary dealers. The Company purchases and sells credit protection under RPAs with the objective of sharing with financial institution counterparties some of the credit exposure related to interest rate derivative contracts entered into with commercial borrowers related to participations purchased or sold. The Company will make or receive payments under these agreements if a customer defaults on an obligation to perform under certain interest rate derivative contracts. The Company also enters into foreign currency forward derivative contracts with commercial borrowers to enable borrowers to manage their exposure to foreign currency fluctuations. The Company enters into offsetting forward contracts with primary dealers to mitigate the foreign currency risk associated with these contracts. These derivative contracts are not designated as hedging instruments; therefore, changes in the fair value of these derivatives are recognized immediately in earnings. The impact on earnings related to changes in fair value of these derivatives was not material for the three and nine months ended September 30, 2024 and 2023.

The Company may be exposed to credit risk in the event of non-performance by the counterparties to its commercial customer derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements, central clearing mechanisms and counterparty limits. The agreements contain bilateral collateral arrangements with the amount of collateral to be posted generally governed by the settlement value of outstanding swaps. The Company manages the risk of default by its commercial borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any significant losses from failure of interest rate derivative counterparties to honor their obligations.

The following table summarizes the Company's derivatives not designated as hedging instruments as of the dates indicated (in thousands):

(1)Fair values of these derivatives are included in other assets and other liabilities in the consolidated balance sheets.

Some of the Company’s ISDA master agreements with financial institution counterparties contain provisions that permit either counterparty to terminate the agreements and require settlement in the event that regulatory capital ratios fall below certain designated thresholds, upon the initiation of other defined regulatory actions or upon suspension or withdrawal of the Bank’s credit rating. Currently, there are no circumstances that would trigger these provisions of the agreements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 1 Basis of Presentation and Summary of Significant Accounting Policies BankUnited, Inc. is a national bank holding company with one wholly-owned subsidiary, BankUnited, collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking services to individual and corporate customers through banking centers in Florida, the New York metropolitan area and Dallas, Texas. The Bank also offers certain commercial lending and deposit products through national platforms and regional wholesale banking offices. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, these financial statements do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with GAAP and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2024, are not necessarily indicative of the results that may be expected in future periods. The Company has a single operating segment and thus a single reportable segment. While management monitors the revenue streams of its various business units, the business units serve a similar base of primarily commercial clients, providing a similar range of products and services, managed through similar processes and platforms. The Company’s chief operating decision maker makes company-wide resource allocation decisions and assessments of performance based on a collective assessment of the Company’s operations. Accounting Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates. The most significant estimate impacting the Company's consolidated financial statements is the ACL. New Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2024 ASU No. 2023-02—Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures using the Proportional Amortization Method (A Consensus of the Emerging Issues Task Force). This ASU was issued to expand the use of the proportional amortization method of accounting for equity investments in tax credit programs beyond those in LIHTC programs. The ASU allows entities to elect the proportional amortization method, on a tax credit program by tax credit program basis, for all equity investments in tax credit programs meeting the eligibility criteria. The Company adopted this ASU in the first quarter of 2024. There was no impact upon adoption. Currently, all of the Company's equity investments in tax credit programs are in LIHTC programs already accounted for using the proportional amortization method. Accounting Pronouncements Not Yet Adopted ASU No. 2023-07—Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU augments reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment and contain other disclosure requirements. This ASU is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. This ASU is not expected to have an impact on the Company's consolidated financial position, results of operations and cash flows. Adoption will result in additional disclosures beginning with the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

The Company monitors its investment securities available for sale for credit loss impairment on an individual security basis. No securities were determined to be credit loss impaired during the three and nine months ended September 30, 2024 and 2023. At September 30, 2024, the Company did not have an intent to sell securities that were in significant unrealized loss positions, and it was not more likely than not that the Company would be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position including its ability to pledge securities to generate liquidity, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors. We have not sold, and do not anticipate the need to sell, securities in unrealized loss positions to generate liquidity.

At September 30, 2024, 421 securities available for sale were in unrealized loss positions. The amount of impairment related to 109 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.9 million and no further analysis with respect to these securities was considered necessary.

The basis for concluding that AFS securities were not credit loss impaired and no ACL was considered necessary at September 30, 2024, is further discussed below.

Unrealized losses were primarily attributable to a sustained higher interest rate environment and in some cases, wider spreads compared to levels at which securities were purchased. The investment securities AFS portfolio was in a net unrealized loss position of $338.0 million at September 30, 2024, compared to $534.8 million at December 31, 2023, improving by $196.8 million during the nine months ended September 30, 2024. While the majority of securities in the portfolio were floating rate at September 30, 2024, fixed rate securities accounted for the majority of unrealized losses.

U.S. Government, U.S. Government Agency and Government Sponsored Enterprise Securities

At September 30, 2024, four U.S. treasury, 58 U.S. Government agency and sponsored enterprise residential MBS, 22 U.S. Government agency and sponsored enterprise commercial MBS, and 20 SBA securities were in unrealized loss positions. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government. As such, there is an assumption of zero credit loss and the Company expects to recover the amortized cost basis of these securities.

Private Label Securities:

None of the impaired private label securities had missed principal or interest payments or had been downgraded by a NRSRO at September 30, 2024. The Company performed an analysis comparing the present value of cash flows expected to be collected to the amortized cost basis of impaired securities. This analysis was based on a scenario that we believe to be generally more conservative than our reasonable and supportable economic forecast at September 30, 2024, and incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity and other relevant factors as described further below. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.

Private label residential MBS and CMOs

At September 30, 2024, 112 private label residential MBS and CMOs were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality measures such as FICO, LTV, documentation, loan type, property type, agency availability criteria and performing status. We also regularly monitor sector data including home price appreciation, forbearance, delinquency, special servicing and prepay trends as well as other economic data that could be indicative of stress in the sector. Underlying delinquencies in this sector remain low. Our September 30, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 2% compared to weighted average credit support of 18%. As of September 30, 2024, 96% of impaired securities in this category, based on carrying value, were externally rated AAA and 4% were rated AA.

Private label commercial MBS

At September 30, 2024, 75 private label commercial MBS were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, voluntary prepayment rates, loss severity, delinquencies and recovery lag. In developing those assumptions, we took into account collateral quality and type, loan size, loan purpose and other qualitative factors. We also regularly monitor collateral concentrations, collateral watch lists, bankruptcy data, defeasance data, special servicing trends, delinquency and other economic data that could be indicative of stress in the sector. We consider collateral, deal, sector and tranche level performance as well as maturity and refinance risk. While we have observed some deterioration in collateral performance in this segment, particularly in the office sector, the high credit quality of these securities and adequacy of subordination to cover projected collateral losses supports the conclusion that there is no credit loss impairment. Our September 30, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 7% compared to weighted average credit support of 46%. As of September 30, 2024, 82% of impaired securities in this category, based on carrying value, were externally rated AAA, 14% were rated AA and 4% were rated A. There is no single-asset, single-borrower exposure.

Single family real estate-backed securities

At September 30, 2024, nine single family rental real estate-backed securities were in unrealized loss positions. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies and recovery lag. We regularly monitor sector data including home price appreciation, forbearance, delinquency and prepay trends as well as other economic data that could be indicative of stress in the sector. We consider collateral, deal, sector and tranche level performance as well as maturity and refinance risk. Our September 30, 2024 analysis projected weighted average collateral losses for this category of 7% compared to weighted average credit support of 53%. As of September 30, 2024, 53% of impaired securities in this category, based on carrying value, were externally rated AAA, 20% were rated AA and one security was not externally rated.

Collateralized loan obligations

At September 30, 2024, two collateralized loan obligations were in unrealized loss positions. Unrealized losses totaled less than 1% of total amortized cost of this segment at September 30, 2024. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, and delinquencies, calibrated to take into account idiosyncratic risks associated with the underlying collateral. In developing those assumptions, we took into account each sector’s performance pre-, during and post the 2008 financial crisis. We regularly engage with bond managers to monitor trends in underlying collateral including potential downgrades and subsequent cash flow diversions, liquidity, ratings migration, and any other relevant developments. While we have observed some deterioration in underlying collateral performance due in large part to rising costs, the high credit quality of these securities and adequacy of subordination to cover projected collateral losses supports the conclusion that there is no credit loss impairment. Our September 30, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 22% compared to weighted average credit support of 42%. As of September 30, 2024, 100% of the impaired securities in this category, based on carrying value, were externally rated AAA.

Non-mortgage asset-backed securities

At September 30, 2024, five non-mortgage asset-backed securities were in unrealized loss positions. These securities are backed by student loan collateral. Our analysis of cash flows expected to be collected on these securities incorporated assumptions about collateral default rates, loss severity, delinquencies, voluntary prepayment rates and recovery lag. In developing assumptions, we took into account collateral type, delineated by whether collateral consisted of loans to borrowers in school, refinancing, or a mixture. Our September 30, 2024 analysis projected weighted average collateral losses for impaired securities in this category of 4% compared to weighted average credit support of 26%. As of September 30, 2024, 30% of the impaired securities in this category, based on carrying value, were externally rated AAA, and 70% were rated AA.

State and Municipal Obligations

At September 30, 2024, five state and municipal obligations were in unrealized loss positions. Our analysis of potential credit loss impairment for these securities incorporates a quantitative measure of the underlying obligor's credit worthiness provided by a third-party vendor as well as other relevant qualitative considerations. As of September 30, 2024, 93% of the impaired securities in this category, based on carrying value, were externally rated AAA and 7% were rated AA

The ACL was determined utilizing a 2-year reasonable and supportable forecast period. The quantitative portion of the ACL was determined using three weighted third-party provided economic scenarios.

The ACL increased by $25.6 million, to 0.94% of total loans at September 30, 2024 from 0.82% of total loans at December 31, 2023. The more significant factors increasing the ACL for the nine months ended September 30, 2024 were an increase in specific reserves and risk rating migration, an increase in qualitative reserves, and changes in portfolio composition and characteristics. These factors increasing the ACL were partially offset by an improved economic forecast and net charge-offs.
