Partners Group builds on the substantial research base provided by the Sustainability Accounting Standards Board (SASB). SASB has provided industry briefs that justify the short list of 15-25 ESG factors and metrics deemed most material for a given industry. The industry briefs also provide the basis for claiming materiality by identifying which specific aspects of a company's financial performance are affected by a given ESG factor. Partners Group uses these industry briefs to sharpen its ESG analysis and ensure full integration with the evaluation of the overall business case. In particular, for debt investments, we focus on risk factors, rather than on opportunities to create value, given our limited influence. In addition, SASB's materiality map informs our internal ESG due diligence assessment, which investment teams must complete for every potential debt investment and submit in their memo to our investment committee. This assessment systematically identifies the most material ESG factors for a given industry.
On an annual basis, we review and update our internal database of material ESG factors included in our ESG DD assessment tool to ensure that it is current. We also introduce non-industry-based factors such as geography-based considerations to help sharpen our analysis. For example, in 2019, we added an ESG factor to our assessment tool which analyzes fraud risk based on Transparency International's Corruption Perceptions Index, a geography-based framework.
For ESG monitoring engagement, our Primera Insight tool scans the internet for ESG-related news for our entire portfolio, including debt investments. ESG-related news on our investments are tracked in our internal database. Based on the circumstances, we engage with the sponsor to understand the reported ESG issues and push for improvements.
