Insights
Aberdeen agrees to take over £1.5bn of MFS closed-end fund mandates via mergers.
Aberdeen Investments has agreed to acquire the management of closed-end fund assets totalling £1.5bn from MFS. The structure involves mergers and reorganisations of nine MFS funds with one existing Aberdeen fund, consolidating them into two larger closed-end vehicles. The manager of the resulting funds will be Aberdeen’s Global Head of Fixed Income, with one fund positioned as a multi-sector bond strategy including private credit.
The transaction is described as income accretive from year one, indicating that Aberdeen expects fee income to exceed any associated costs on a near-term basis. The deal is subject to approval by shareholders of the affected funds, so completion depends on those votes. Aberdeen notes this will be its 10th US closed-end fund acquisition since 2000 and that it currently manages about £21.4bn in closed-end funds out of approximately £382bn in total assets as of 30 September 2025, reinforcing its role as a large global player in this niche.
For investors in the involved funds, the change primarily affects who manages the portfolios and the eventual fund line-up, moving to two larger funds with a focus on fixed income and private credit. Actual outcomes for fees, discounts and performance will depend on how the merged funds are structured and managed after shareholder approvals and implementation.

Aberdeen enters into agreement with MFS to acquire management of Closed End Funds with assets totalling £1.5bn
Aberdeen Investments (‘Aberdeen’) has reached agreement with MFS to acquire the management of closed end fund (CEF) assets totalling £1.5bn, further cementing Aberdeen’s position as the fifth largest asset manager of CEFs globally.
Through a series of mergers and reorganisations, nine MFS funds, in addition to one existing Aberdeen closed end fund, will be consolidated resulting in two active closed end funds. Both combined funds will benefit from significant scale, creating a springboard for potential future growth:
| - | four MFS municipal bond CEFs and one Aberdeen Municipal bond CEF will be consolidated to create a c.$1bn AUM municipal bond fund |
| - | five MFS taxable fixed income funds will be merged to create a c.$1.4bn AUM multi-sector fixed income CEF (including private credit) |
As one of the largest managers of CEFs in the world, Aberdeen is well placed to support consolidation in the sector, helping to deliver larger funds that benefit from economies of scale and offer greater liquidity for investors. No staff or corporate entities will transfer as part of the transaction, and the acquisition is income accretive from year one. The deal remains subject to approval by the shareholders of the respective funds.
