BlackRock ESG Capital Allocation Trust's (ECAT) (the 'Trust') investment objectives are to provide total return and income through a combination of current income, current gains and long-term capital appreciation. The Trust invests in a portfolio of equity and debt securities. Generally, the Trust's portfolio will include both equity and debt securities. At any given time, however, the Trust may emphasize either debt securities or equity securities. The Trust will invest at least 80% of its total assets in securities that, in the Advisor?s assessment, meet the environmental, social and governance ("ESG") criteria as described in the Trust's prospectus and shareholder reports. The Trust utilizes an option writing (selling) strategy in an effort to generate current gains from options premiums and to enhance the Trust's risk-adjusted returns.
