DBRS Morningstar Confirms Ratings on the Class A-1 Notes Issued by Portman Ridge Funding 2018-2 Ltd.

DBRS, Inc. (DBRS Morningstar) confirmed its AAA (sf) ratings on the Class A-1R-R Senior-Secured Revolving Floating-Rate Notes (the Class A-1R-R Notes) and the Class A-1T-R Senior-Secured Floating-Rate Notes (the Class A-1T-R Notes; together with the Class A-1R-R Notes, the Class A-1 Notes) issued by Portman Ridge Funding 2018-2 Ltd. (the Issuer or Portman Ridge CLO) pursuant to the Indenture dated as of October 18, 2018, as amended from time to time, among the Issuer; Portman Ridge Funding 2018-2 LLC as Co-Issuer; and Deutsche Bank Trust Company Americas as Trustee. DBRS Morningstar notes that the Issuer’s name was changed to Portman Ridge Funding 2018-2 Ltd. from Garrison Funding 2018-2 Ltd. pursuant to the Fourth Supplemental Indenture dated as of September 17, 2021.

The rating on the Class A-1R-R Notes addresses the timely payment of interest up to the Interest Rate Cap (as defined in the Indenture) and the ultimate payment of principal on or before the Stated Maturity (as defined in the Indenture). The rating on the Class A-1R-R Notes does not address the payment of any Class A-1R Note Additional Amount (as defined in the Indenture). The rating on the Class A-1T-R Notes addresses the timely payment of interest and the ultimate payment of principal on or before the Stated Maturity (as defined in the Indenture).

RATING RATIONALE
The rating confirmations are a result of DBRS Morningstar’s surveillance review following the transaction exiting its Reinvestment Period on November 20, 2022, and the underlying collateral pool becoming static. Given the static pool, DBRS Morningstar analyzed the actual obligations in the pool as opposed to a hypothetical pool, governed by the covenanted test limitations. DBRS Morningstar confirmed its ratings on the Class A-1 Notes as the transaction is performing within expectations.

The Class A-1 Notes issued by Portman Ridge CLO are collateralized primarily by a portfolio of U.S. senior-secured middle-market corporate loans (the Assets) and are managed by Portman Ridge Finance Corporation as Collateral Manager and Sierra Crest Investment Management LLC as Sub-Collateral Manager.

In its analysis, DBRS Morningstar considered the following aspects of the transaction:
(1) The transaction’s capital structure and the form and sufficiency of available credit enhancement.
(2) Relevant credit enhancement in the form of subordination and excess spread.
(3) The ability of the Class A-1 Notes to withstand projected collateral loss rates under various cash flow stress scenarios.
(4) The credit quality of the underlying collateral.
(5) DBRS Morningstar’s assessment of the origination, servicing, and collateralized loan obligation (CLO) management capabilities of Portman Ridge Finance Corporation, Sierra Crest Investment Management LLC, and BC Partners as Affiliate. DBRS Morningstar considers BC Partners an acceptable CLO manager.
(6) The legal structure as well as legal opinions addressing certain matters of the Issuer and the consistency with the DBRS Morningstar “Legal Criteria for U.S. Structured Finance” methodology.

Some particular strengths of the transaction are (1) significant overcollateralization (OC) cushion levels above the trigger levels, showing substantial subordination for the Class A-1 Notes, and (2) the collateral quality, which consists entirely of senior-secured middle-market loans. Some challenges are (1) failures in some of the Collateral Quality Tests and (2) some Collateral Loans in the portfolio have experienced a default.
The transaction entered its amortization period on November 20, 2022, which assumes limited reinvestment abilities. To account for the static pool, DBRS Morningstar analyzed the actual obligations in the pool as reported in the trustee report on April 3, 2023. The Coverage Tests that DBRS Morningstar modeled in its analysis are presented below:

Coverage Tests:
OC Ratio: 128.00%
Interest Coverage Ratio: 125.00%

DBRS Morningstar modeled the transaction using the DBRS CLO Asset Model and its proprietary cash flow engine, which incorporated assumptions regarding principal amortization, amount of interest generated, default timings, and recovery rates, among other credit considerations referenced in the DBRS Morningstar rating methodology “Cash Flow Assumptions for Corporate Credit Securitizations” (February 7, 2023; www.dbrsmorningstar.com/research/409499).

DBRS Morningstar analyzed each loan in the pool separately by inputting its tenor, DBRS Morningstar rating, country of origin, and industry into the DBRS CLO Asset Model. The model-based analysis, along with the cash flow engine output, produced satisfactory results, which supported the rating confirmations on the Class A-1 Notes.

The Events of Default (EODs) contain an EOD OC Ratio trigger; however, the Assets securing the Class A-1 Notes may not be sold unless the Trustee determines that the liquidation proceeds would be sufficient to repay all interest and principal on the Class A-1 Notes, or Holders of at least a majority of each Class of Class A-1 Notes (voting separately by Class) consent to and direct the sale and liquidation of the Assets (all capitalized terms as defined in the Indenture).

To assess portfolio credit quality, DBRS Morningstar provides a credit estimate or internal assessment for each nonfinancial corporate obligor in the portfolio not rated by DBRS Morningstar. Credit estimates are not ratings; rather, they represent a model-driven default probability for each obligor that is used in assigning ratings to a facility.

The transaction assumptions consider DBRS Morningstar’s baseline macroeconomic scenarios for rated sovereign economies, available in its commentary “Baseline Macroeconomic Scenarios for Rated Sovereigns: April 2023 Update” (https://www.dbrsmorningstar.com/research/413218). These baseline macroeconomic scenarios replace DBRS Morningstar’s moderate and adverse Coronavirus Disease (COVID-19) pandemic scenarios, which were first published in April 2020.
