CD 2017-CD4 Mortgage Trust Annual Review: Understanding Your Investment

This annual review examines the CD 2017-CD4 Mortgage Trust for the fiscal year ended December 31, 2023. It clarifies the trust's structure and highlights key operational aspects.

1. Business Overview

The CD 2017-CD4 Mortgage Trust is not a traditional operating company with publicly traded stock. Instead, it functions as a commercial mortgage-backed securities (CMBS) trust. This means it is a special investment vehicle that holds a pool of commercial mortgage loans. The trust issues various classes of certificates to investors, passing through income generated from borrowers' loan payments (minus expenses) to these certificate holders. Investors in this trust hold these certificates, not common stock.

The trust's assets primarily consist of specific commercial mortgage loans. Many of these loans are "loan combinations," meaning the trust owns an "equal-footing" (pari passu) portion of a larger loan.

Key Loans (Initial Percentage of Trust Assets):

• Moffett Place Google Mortgage Loan: Approximately 8.3%
• Hilton Hawaiian Village Mortgage Loan: Approximately 6.3%
• Uovo Art Storage Mortgage Loan: Approximately 5.5%
• Key Center Cleveland Mortgage Loan: Approximately 3.3%
• 111 Livingston Street Mortgage Loan: Approximately 2.7%
• Hamilton Crossing Mortgage Loan: Approximately 2.2%

Management of Trust Assets: A network of specialized companies administers and services the trust's loans:

• Midland Loan Services: Serves as the Master Servicer. For fiscal year 2023, Midland Loan Services confirmed it met all its obligations under the servicing agreement, demonstrating proper operational compliance and administration of the loan pool.
• K-Star Asset Management LLC and Rialto Capital Advisors, LLC: These firms act as Special Servicers. Their role is to step in and manage loans that become delinquent or default, working to maximize recovery for the trust.
• Wells Fargo Bank, National Association: Previously served as a primary servicer for some loans and continues as a certificate administrator. They also act as a custodian for many loan documents.
• Trimont LLC: Took over as primary servicer for specific loans (e.g., Hilton Hawaiian Village, Key Center Cleveland, Hamilton Crossing) from March 2023 onwards, following a transition from Wells Fargo.
• Computershare Trust Company, National Association (CTCNA): Also assumed some servicing tasks from Wells Fargo.
• Other Key Roles: Park Bridge Lender Services LLC (Operating Advisor), Deutsche Bank Trust Company Americas (Custodian for some loans), and CoreLogic Solutions, LLC (Tax services).

2. Risk Factors

Investing in CMBS trusts like CD 2017-CD4 Mortgage Trust involves various risks that could materially affect the value of the certificates and the distributions to investors. Typical risks include:

• Credit Risk: The risk that borrowers on the underlying commercial mortgages will default on their payments, leading to potential losses for the trust.
• Interest Rate Risk: Changes in prevailing interest rates can affect the market value of the trust's certificates and the likelihood of prepayments on the underlying loans.
• Prepayment Risk: Loans paying off earlier than expected can reduce future interest income and may require reinvestment of proceeds at potentially lower rates.
• Extension Risk: Loans paying off later than expected can tie up capital for longer periods than anticipated, affecting the timing of cash flows.
• Servicer Performance Risk: The risk that the master or special servicers may not effectively manage the loans, especially troubled assets, which could negatively impact recovery rates.
• Concentration Risk: If a significant portion of the trust's assets are concentrated in a few large loans, specific property types, or particular geographic regions, adverse events affecting those areas could have a disproportionate impact on the trust's performance.
• Market Value Risk: The market value of the trust's certificates can fluctuate based on prevailing interest rates, credit spreads, and the performance and perceived risk of the underlying loans.
• Liquidity Risk: The market for CMBS certificates may not always be liquid, making it difficult to sell certificates at desired prices or at all.

3. Competitive Position

For a CMBS trust, the concept of "competitive position" is not typically discussed in the same manner as for an operating company that competes for market share or customers. A trust is a passive investment vehicle. Its "position" might implicitly relate to the quality, diversity, and performance of its underlying loan collateral compared to other CMBS deals in the market, or the reputation of its originators and servicers. However, it does not engage in competitive activities.

Conclusion for Investors

The CD 2017-CD4 Mortgage Trust functions as a pass-through vehicle for commercial mortgage loan income, holding a pool of commercial mortgage loans. Key loans include Moffett Place Google, Hilton Hawaiian Village, and Uovo Art Storage, among others. Midland Loan Services, the Master Servicer, confirmed it met all its obligations for 2023. Investors should be aware that CMBS investments inherently carry risks such as credit, interest rate, and prepayment risks.
