Role description
The Portfolio Management team within DGG is responsible for leading the due diligence on new transactions as we build GGC’s guarantee portfolio, ensuring alignment with GGC’s risk appetite and impact objectives. GGC aims to mobilise institutional capital from global capital and credit markets to finance climate adaptation and mitigation projects in EMDEs at scale.
The Assistant Portfolio Manager will support the Chief Underwriting Officer and Portfolio Manager in the credit analysis and due diligence of transactions, and ongoing monitoring of the portfolio. The role will also work closely with colleagues in the Structuring & Execution Team to support the early stage review of potential opportunities as required, and with the DGG Climate and E&S Specialists to ensure that the best guarantee opportunities in the pipeline are being selected to build and maintain a well performing guarantee portfolio that achieves GGC’s goals.
Responsibilities
Transaction Due Diligence — 60% of time (estimated)
Responsible for credit due diligence workstreams on transactions. Prepare new business and final credit approval memos for committee with guidance from the Chief Underwriting Officer, and present clearly at Credit Committee. Ensure that transaction deadlines are met, any red flags are raised early with the relevant colleagues, and a clear credit thesis is articulated.
Conduct quantitative and qualitative credit analysis of transactions, applying a systematic approach (rating methodology). For example: assess financial structure and key documentation, company track record and business plan, legal and regulatory environment, industry analysis, market and technical due diligence, develop internal financial base cases using various techniques and scenario analysis, justifying assumptions and highlighting key financial sensitivities.
Collaborate with DGG’s Climate and E&S Specialists to identify and assess relevant risks.
Work closely with DGG’s Senior Advisor, Structuring & Execution and colleagues to identify key information gaps and drivers of creditworthiness up front.
Collaborate with and support DGG business development and impact colleagues to successfully convert guarantee opportunities into closed transactions that maximise climate impact.
Portfolio management — 35% of time (estimated)
Build and maintain strong relationships with GGC portfolio clients ensuring information flow, proactive monitoring and risk management to achieve intended financial and impact results.
Proactively refresh internal credit view of assigned transactions as part of regular monitoring of borrower reports, covenant compliance and management meetings. Maintain watch lists and escalate material credit deterioration and potential borrower defaults to the Chief Underwriting Officer.
Collaborate with and support DGG operations and impact colleagues to collate and analyse client performance data to prepare portfolio, sectoral and thematic reports per the GGC’s monitoring, reporting and verification framework (where applicable) and for any stakeholders as required.
Identify opportunities to improve the portfolio management process, efficiency and controls.
Support with the restructuring of guarantees (if required) in a manner that contributes to the wider agenda of GGC to build confidence with global capital and credit markets and enhances the reputation and capability positioning of DGG as its manager.
Market advocacy — 5% of time (estimated)
Represent GGC’s mission and the role of guarantees as an effective ambassador in external interactions. Support colleagues in researching and preparing speaking notes for relevant industry conferences and events, and seek to build presence and experience as a presenter at such events over time.
Disseminate insights from portfolio data to other DGG colleagues that contribute to the wider learning agenda of DGG, to further the reputation and capability positioning of the team, and to inform strategic decisions and align GGC’s guarantee solutions with market expectations.
