Company Description
Investment process
This fund seeks investments that contribute to a more sustainable world. To achieve this, it adopts a highly active investment approach, investing globally in a sustainable portfolio with at least 60% in government bonds, corporate bonds and investment grade credit (each with a credit rating of AAA to BBB-). Up to 40% of the fund may be invested in government, corporate and high yield bonds, directly in emerging markets and sovereign debt (each with a credit rating below BBB- or with no rating at all).
Its investment strategy combines a ‘top-down’ perspective - assessing value at the country, industry, and sector level - with rigorous ‘bottom-up’ analysis, evaluating individual issuers and bonds. Ideas come from numerous areas including macroeconomic factors, sectoral and regional trends, supply and demand dynamics, new issuances, regulatory issues, interest rate policies, and the firm’s sustainable development themes.
Corporate bonds are the core of the fund, with credit selection based on a ‘four Cs plus’ approach. This framework assesses the integrity and competence of management teams (character); the availability of cash flows and assets to meet obligations (capacity); the quality of assets offered as security (collateral); and the details of bond agreements and lending restrictions (covenants). The ‘plus’ is conviction, which is based upon being patient and contrarian. Environmental, social, and governance (ESG) risks are also assessed for their potential impact on company performance.
Once they’ve developed themes and carried out in-depth credit analysis, the team assesses bond valuations. The fund also seeks to identify technically undervalued bonds, even if they score lower on credit analysis. The final portfolio consists of around 180-200 holdings.
Risk
Before an investment is added to the portfolio, it must pass through a comprehensive risk framework. This process examines how the new position aligns with the fund’s economic outlook, asset allocation, duration, yield, issuer exposure and liquidity. While risk monitoring is a key component, it does not dictate investment decisions but rather ensures that portfolio adjustments are well calculated and in line with the fund’s strategy.
ESG
ESG - Explicit
Every investment is screened against sustainability criteria by Greenbank’s Ethical, Sustainable, and Impact research team. This screening process excludes entities with activities that hinder sustainable development, while prioritising those that generate positive social and environmental outcomes. Greenbank holds the authority to veto any investment that does not meet its sustainability standards.
