An asset management firm manages pooled funds and individual segregated portfolios. One of the managers proposes that the firm start evaluating the ESG composition of client portfolios by uploading the portfolios onto a third-party ESG platform. Which of the following is least likely an advantage of the proposal?

选项：

A.It is suitable for all the firm’s clients.

B.It can produce a picture of each client’s carbon exposure.

C.It can approximate an overall controversy or risk score for the portfolio.

解释：

A is correct. The proposal is not suitable for all clients. Uploading portfolios to a third-party platform can have many advantages, including illustrating a portfolio’s mean exposure and weighting toward low-, mid-, or high-scoring companies on ESG metrics; producing a picture of the portfolio’s environmental and carbon exposure on an absolute-value basis, for instance, expressed as weighted-average carbon intensity; and approximating an overall controversy or risk score for the portfolio. However, third-party platforms are not suitable if there are concerns around privacy issues. A client may also not be concerned about ESG integration in their portfolio and hence not interested in the potential information that can be gained from such a platform.
