@robbinsforster7752, I do not think the "Investment Advisor" company is available in Eikon data API / Eikon Excel. I only see Fund Company and Custodian in Eikon API.

That data field is available in the newer RDP Funds API. Below is the data I obtained from the sample fund: LP68405497. Notes, your screenshot shows that fund in the chart, but the advisor screen you showed is not for that fund.

Sample data from RDP Funds API:

       {
          "code": "INVESTMENT_ADVISOR",
          "type": {
            "id": "392",
            "name": "Investment Advisor"
          },
          "values": [
            {
              "name": "Ninety One UK",
              "code": "0008",
              "addressLine1": "55 Gresham Street",
              "city": "LONDON",
              "postalCode": "EC2V 7EL",
              "country": "United Kingdom",
              "telephone": "442039382000",
              "webSite": "https://ninetyone.com/en/international/",
              "date": "1800-01-01"
            }
          ]
