Invesco has updated the investment policy and implemented index methodology changes of a set of corporate bond and emerging markets ETFs in an effort to strengthen their ESG criteria.

Effective from 30 November, the firm will update the investment policy of the Invesco GBP Corporate Bond ESG UCITS ETF, Invesco USD High Yield Corporate Bond ESG UCITS ETF and the Invesco MSCI Emerging Markets ESG Universal Screened UCITS ETF to include ESG as an underlying strategy.

Under the new investment policy, the firm said the funds may now hold some securities "which are not component securities of the reference index, but are similar to them and whose risk, return and ESG characteristics that closely resemble the risk, return and ESG characteristics of constituents of the reference index or the reference index as a whole".

In a letter to investors, the firm said that the Invesco USD IG Corporate Bond ESG UCITS ETF, Invesco EUR IG Corporate Bond ESG UCITS ETF and Invesco GBP Corporate Bond ESG UCITS ETF will now include additional metrics such as excluding companies that do not have an MSCI ESG rating or controversy score.

Each reference index will also include an issuer cap of 5% and have their names changed to include social responsible investment (SRI).
