First Trust Files 13G/A: 13.28% Stake in IGI Disclosed

On 28 Jul 2025 First Trust Portfolios L.P., First Trust Advisors L.P. and their general partner, The Charger Corporation, filed Amendment 22 to Schedule 13G on Western Asset Investment Grade Opportunity Trust Inc. (IGI).

Rhea-AI Filing Summary

On 28 Jul 2025 First Trust Portfolios L.P., First Trust Advisors L.P. and their general partner, The Charger Corporation, filed Amendment 22 to Schedule 13G on Western Asset Investment Grade Opportunity Trust Inc. (IGI). The group reports beneficial ownership of 795,809 common shares, equal to 13.28 % of the outstanding class as of the event date 30 Jun 2025.

The stake is held primarily through unit investment trusts (UITs) sponsored by First Trust Portfolios; First Trust Advisors acts as portfolio supervisor. No individual UIT holds more than 3 % of IGI. The reporting persons disclaim beneficial ownership and retain shared dispositive power over all 795,809 shares but zero voting power; voting rights rest with the UIT trustees to mirror external shareholders. Entity classifications: First Trust Portfolios = broker-dealer (BD), First Trust Advisors = investment adviser (IA), The Charger Corporation = holding company (HC).

The certification states the securities were acquired in the ordinary course and not for the purpose of influencing control of IGI. No other material transactions, financial results or strategic intentions are disclosed.

Positive

• Significant institutional interest: First Trust group controls 13.28 % of IGI’s shares, potentially supporting liquidity and market visibility.

Negative

• No voting power disclosed: The 13 % stake lacks voting authority, limiting support in shareholder matters and providing no insight into governance stance.
• Potential redemption overhang: Unit investment trusts have finite lives; future UIT liquidations could add selling pressure on IGI shares.

Insights

Portfolio Manager

TL;DR: First Trust passive filing shows 13.28 % ownership; no voting power, limited governance impact.

The Schedule 13G is a passive filing, signalling that First Trust’s UIT complex has aggregated a sizeable position in IGI. At >13 %, the stake is material, raising float concentration and potentially improving secondary-market liquidity. Because voting rights are delegated to trustees and the group disclaims control intent, near-term governance influence is minimal. Investors should note that UIT holdings can unwind as trusts mature, introducing periodic supply risk. Overall, information content is moderate and does not alter IGI’s fundamental outlook.

This Schedule 13G filing is jointly filed by The Charger Corporation, First Trust Portfolios L.P. and First Trust Advisors L.P. pursuant to Rule 13d-1(k)(1). The Charger Corporation is the General Partner of both First Trust Portfolios L.P. and First Trust Advisors L.P. First Trust Portfolios L.P. acts as sponsor of certain unit investment trusts which hold shares of the issuer. The total number of shares of the issuer held by these unit investment trusts is set forth in Row (8) above with respect to First Trust Portfolios L.P. No individual unit investment trust sponsored by First Trust Portfolios L.P. holds more than 3% of any registered investment company issuer's shares. First Trust Advisors L.P., an affiliate of First Trust Portfolios L.P., acts as portfolio supervisor of the unit investment trusts sponsored by First Trust Portfolios L.P., certain of which hold shares of the issuer. Neither First Trust Portfolios L.P., First Trust Advisors L.P. nor The Charger Corporation have the power to vote the shares of the issuer held by these unit investment trusts sponsored by First Trust Portfolios L.P. These shares are voted by the trustee of such unit investment trusts so as to insure that the shares are ordinarily voted as closely as possible in the same manner and in the same general proportion as are the shares held by owners other than such unit investment trusts. Subject to the requirements of Rule 12d1-4 under the Investment Company Act of 1940 and as further explained in the Standard Terms and Conditions of Trust and related Trust Agreements of the unit investment trusts, First Trust Portfolios L.P., on behalf of the unit investment trusts, may enter into an agreement with a deposited fund which may permit the shares of such fund to be voted in the best interest of unit holders at the discretion of First Trust Portfolios L.P. The difference, if any, between the aggregate amount of shares beneficially owned by each reporting person, as set forth in Row (9) above, and the number of shares of the issuer held by the unit investment trusts sponsored by First Trust Portfolios L.P. represents shares of the issuer which are either held in other registered investment companies, pooled investment vehicles and/or separately managed accounts for which First Trust Advisors L.P. serves as investment advisor and/or investment sub-advisor. Each of First Trust Portfolios L.P., First Trust Advisors L.P. and The Charger Corporation disclaims beneficial ownership of the shares of the issuer identified in this filing.
