Highland/iBoxx Senior Loan ETF (SNLN) is an exchange-traded fund that seeks to provide investment results corresponding generally to the price and yield performance, before fees and expenses, of the Markit iBoxx USD Liquid Leveraged Loan Index. The fund invests primarily in a portfolio of approximately 100 of the most liquid senior loans issued in U.S. dollars with at least one year remaining to maturity; these loans are selected based on liquidity measures such as the number of active trading participants, trade size, and frequency of pricing data, and are market-value weighted. Top holdings include Dreyfus Treasury Obligations Cash Management (37.24%), Grifols Worldwide Term Loan (7.94%), Prime Security Services Borrower (7.92%), Charter Communications Operating Term Loan (7.88%), and American Airlines (7.84%), among others in sectors such as technology services, information, and transportation.
SNLN was launched on November 6, 2012, and trades on the NASDAQ exchange under the ticker SNLN; it is managed by NexPoint Asset Management, L.P. (formerly associated with Highland Capital Management), with Matt Pearson as the fund manager. The fund targets investors seeking high-yield fixed income exposure through senior secured loans in developed North American markets; it features a net expense ratio of 0.56% (after fee waivers), assets under management of approximately $30.7 million, and a dividend yield of around 7.87%.
In recent years, the fund has undergone operational enhancements, including index methodology updates in 2018 implemented by Highland Capital Management following a review by index provider IHS Markit, which introduced a loans substitution process for restructured obligations to better reflect current loan market dynamics. The sponsor announced portfolio manager updates for SNLN, ensuring continuity in its passively managed strategy focused on liquid leveraged loans. As of late 2025, no major acquisitions, funding rounds, or new product launches specific to SNLN have been reported, with the ETF maintaining its core focus amid a stable operational profile.
