This fund lands in the 10% of strategies with the highest ESG risk in the US Fixed Income category, earning it the lowest Morningstar Sustainability Rating of 1 globe. Funds with 4 or 5 globes tend to hold securities that are less exposed to ESG risk. Unlike impact, which focuses on generating positive environmental and societal outcomes, ESG risk measures the degree to which investments could be affected by material ESG issues, including climate change, biodiversity, product safety, community relations, data privacy and security, bribery and corruption, and corporate governance.
One potential issue for a sustainability-focused investor is that Buffalo High Yield Fund doesn’t have an ESG-focused mandate. Funds with an ESG-focused mandate are more likely to align with the expectations of an investor who cares about sustainability issues. One area to watch is the fund’s carbon risk exposure. Its Carbon Risk Score of 23.17 is situated at the higher end of the medium carbon risk band, indicating the fund's investee companies are in a vulnerable position in the transition to a low-carbon economy. The score represented the asset-weighted Carbon Risk Score of the portfolio's equity or corporate bond holdings, averaged over the trailing 12 months.Funds with a lower carbon risk classification may be more favored by investors concerned about transition risks, as such funds often tilt toward companies that operate in sectors less exposed to the transition (for example, healthcare and IT) or companies in more carbon-intensive sectors (for example, materials and utilities) that consider climate change in their business strategy, and therefore are positively aligned with the transition. Currently, the fund has 39.8% involvement in fossil fuels, which is high in both absolute and relative terms. The average peer in the same High Yield Bond category has 12.8% exposure to fossil fuel-related businesses. Companies are considered involved in fossil fuels if they derive at least 5% of their revenue from thermal coal, oil, and gas. The fund has significant exposure (12.69%) to companies with high or severe controversies. Companies with controversies may be involved in incidents such as corruption, employee abuses, environmental incidents, and corporate scandals that pose some degree of business risks to the company. Severe and high controversies can have significant financial repercussions, ranging from legal penalties to consumer boycotts. Such controversies can also damage the reputation of both companies themselves and their shareholders.
