Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? The Funds performance for the fiscal year was driven by the outcomes of the idiosyncratic corporate catalysts in which the Fund invested. Returns were sourced predominantly from the Funds equity special situations investments, though the merger arbitrage and credit opportunities sleeves also contributed to performance. Most of the Funds performance was generated by investments in US-based catalysts. Information technology and energy were the top performing sectors, while health care and materials detracted the most from returns. Top contributors included the acquisition of VMware by Broadcom, Microsofts acquisition of Activision Blizzard, and the Funds investment in Kaleyra bonds. Top detractors included the Funds investments in Pacific Biosciences of California, the merger of Capri Holdings and Tapestry, and Bayer. | ||

Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? The Funds performance for the fiscal year was driven by the outcomes of the idiosyncratic mergers and acquisitions transactions in which the Fund invested, notably including deals that experienced favorable outcomes despite regulatory challenges and a competitive bidding scenario. Returns were sourced predominantly from US-target transactions, though UK-targeted deals also contributed to performance. Health care and industrials were the top performing sectors, while materials and consumer discretionary detracted the most from returns. Top contributors included the acquisition of Seagen by Pfizer, the acquisition of Horizon Therapeutics by Amgen, and the acquisition of Everbridge by Thoma Bravo. Top detractors included the merger of Capri Holdings and Tapestry, the acquisition of United States Steel by Nippon Steel, and the acquisition of ANSYS by Synopsys. | ||
