Bank of America Merrill Lynch Commercial Mortgage Trust 2017-BNK3: Your Annual Performance Snapshot for 2023

This report provides a comprehensive overview of the Bank of America Merrill Lynch Commercial Mortgage Trust 2017-BNK3's performance for the fiscal year ending December 31, 2023. Bank of America Merrill Lynch created this trust in 2017 to hold a diverse portfolio of commercial mortgage loans. By year-end 2023, the trust's outstanding loan balance stood at approximately $875 million, down from its original $1.05 billion, spread across 78 individual loans.

1. Business Overview

The trust invests in various commercial property types, primarily concentrated in:

• Office properties: 35% (Current Debt Service Coverage Ratio (DSCR): 1.25x, Loan-to-Value (LTV): 70%)
• Retail (non-mall): 25% (Current DSCR: 1.40x, LTV: 65%)
• Multifamily: 20% (Current DSCR: 1.55x, LTV: 60%)
• Industrial: 10% (Current DSCR: 1.60x, LTV: 55%)
• Other property types account for the remaining 10%.

The portfolio also shows geographic diversity, with its largest exposures in California (15%), Texas (12%), and Florida (10%). For performing loans, the weighted average Debt Service Coverage Ratio (DSCR) is a healthy 1.38x, and the weighted average Loan-to-Value (LTV) stands at 67% based on original appraisals.

Many loans in the portfolio represent "vertical slices" of larger loans, meaning the trust owns a portion alongside other investors. For instance, 'The Summit Birmingham' loan ($35 million, 4.0% of the portfolio) and the 'FedEx Ground Portfolio' loan ($28 million, 3.2% of the portfolio) are significant examples of these shared investments within the trust.

2. Financial Performance

While most loans performed as expected, the trust's credit performance shifted during 2023:

• Delinquency Rate: As of December 31, 2023, the 30-day delinquency rate stood at 1.5% ($13.1 million), and the 60-day delinquency rate was 0.8% ($7.0 million).
• Special Servicing: Loans totaling $75 million (8.6% of the portfolio) moved to special servicing during the year. These transfers primarily resulted from maturity defaults or declining occupancy in office properties. While 'The Summit Birmingham' loan remains current, the trust closely monitors it due to co-lender issues in other trusts. The 'FedEx Ground Portfolio' loan continues to perform well.
• Losses: The trust recorded $5.2 million in realized losses in 2023. These losses mainly stemmed from liquidating two smaller retail loans previously in special servicing.
• Trust Income and Distributions: The trust primarily generates income from interest payments on its commercial mortgage loans. After covering administrative expenses and servicer fees, the trust distributes these funds to certificate holders following its waterfall structure. The outstanding loan balance decreased from $1.05 billion to $875 million, reflecting both principal payments applied to the trust's certificates and realized losses.

3. Risk Factors

Investing in the trust's certificates involves various risks, including:

• Commercial Real Estate Market Risks: Underlying loan performance highly depends on general economic conditions and the specific dynamics of the commercial real estate market. Downturns, rising interest rates, or oversupply in certain property types can adversely affect property values, occupancy rates, and borrowers' ability to repay their loans.
• Property Type Concentration Risk: The portfolio significantly concentrates in office and retail properties. The office sector, in particular, faces ongoing challenges from remote work trends and declining occupancy, which could lead to further defaults and losses. Retail properties also remain susceptible to e-commerce competition and evolving consumer habits.
• Borrower Default Risk: Individual borrowers may experience financial difficulties, leading to payment defaults, foreclosures, and potential losses for the trust.
• Special Servicing Risk: Loans in special servicing may incur additional costs, experience delays in resolution, and result in greater losses compared to performing loans. The special servicers' effectiveness in maximizing recoveries is crucial.
• Interest Rate Risk: While many CMBS loans are fixed-rate, changes in market interest rates can impact property valuations and borrowers' ability to refinance maturing loans, potentially increasing default risk.
• Servicer Transition Risk: Recent changes in Master, Primary, Trustee, and Certificate Administrator roles introduce operational risks during the transition period. While intended to streamline operations, any disruption could temporarily affect cash flow or reporting.
• Concentration in Larger Loans: The performance of larger loans, such as 'The Summit Birmingham,' can disproportionately impact the trust's overall performance, especially if they experience distress.
• Liquidity Risk for Certificate Holders: Although not directly applicable to the trust's operations, certificate holders may face liquidity risk if no active secondary market exists for the trust's certificates.

4. Management Discussion

The trust's 2023 performance mirrors the broader commercial real estate market, especially the challenges confronting the office sector. A weighted average DSCR of 1.38x and LTV of 67% for performing loans generally indicate a healthy underlying collateral base for most of the portfolio. However, the increase in specially serviced loans to 8.6% of the portfolio, primarily due to maturity defaults and declining office occupancy, highlights areas of concern. The $5.2 million in realized losses from liquidated retail loans underscores ongoing credit challenges within specific segments. The trust proactively monitors loans like 'The Summit Birmingham' due to co-lender issues, managing potential future risks.

The trust's administrative and servicing structure underwent several significant changes:

• Trustee & Certificate Administrator: Computershare Trust Company N.A. now serves as the Trustee and Certificate Administrator. It assumed these responsibilities from Wells Fargo Bank, N.A. effective April 1, 2024, following Wells Fargo's divestiture of its corporate trust business.
• Master & Primary Servicer: Effective March 1, 2024, Trimont LLC assumed the role of Master Servicer and Primary Servicer for a substantial portion of the loans, replacing Wells Fargo Bank, N.A. This change aims to streamline servicing operations.
• Special Servicers: Rialto Capital Advisors, LLC and Situs Holdings, LLC continue to act as Special Servicers. They step in to manage loans encountering payment difficulties or other material defaults. As of year-end, they actively managed the $75 million in specially serviced loans.

The trust implemented these strategic adjustments to ensure efficient management and oversight of its assets. We expect these transitions to streamline operations and enhance the trust's ability to manage its portfolio effectively going forward.

5. Financial Health

The trust's financial health directly depends on the performance of its underlying commercial mortgage loans. As of December 31, 2023, the $875 million outstanding loan balance represents its primary asset base. For most of the portfolio, the healthy weighted average DSCR of 1.38x for performing loans suggests that property cash flows sufficiently cover debt service. The weighted average LTV of 67% (based on original appraisals) indicates a reasonable equity cushion, though current valuations for certain property types, particularly office, may have declined.

The trust primarily derives its liquidity from scheduled principal and interest payments on its mortgage loans. The trust uses these cash flows to make distributions to certificate holders and cover trust expenses. The rise in delinquencies and specially serviced loans indicates a strain on the trust's cash flow generation from those specific assets. This could potentially impact future distributions if losses are higher than anticipated or if resolutions are prolonged. The trust does not incur debt in the traditional sense; its liabilities are the outstanding certificates issued to investors.

6. Future Outlook

The outlook for the Bank of America Merrill Lynch Commercial Mortgage Trust 2017-BNK3 remains subject to the evolving conditions of the commercial real estate market. Investors should continue to monitor the resolution of specially serviced loans, as their successful workout or liquidation will directly impact future realized losses and cash flow available for distribution. The trust expects the recent servicer transitions by Computershare and Trimont LLC to provide efficient management, and their long-term impact on loan resolutions and overall trust efficiency will be a key area for observation.

The trust anticipates continued challenges in the office sector, which constitutes a significant portion of its portfolio. Therefore, it will focus on proactive asset management for these loans. While the portfolio's diversification across property types and geographies provides some resilience, potential headwinds such as sustained higher interest rates, economic slowdowns, or further shifts in property demand could impact borrower performance and property valuations. Servicers will continue to diligently oversee the trust's strategy to maximize recoveries on distressed assets and maintain the performance of the remaining portfolio.

7. Competitive Position

Not applicable for a Commercial Mortgage Trust. A CMBS trust is a passive investment vehicle that holds a pool of mortgage loans and issues securities backed by the cash flows from these loans. It does not operate as a commercial enterprise with a competitive position in the market.
