Western Asset Investment Grade Income Fund Inc. is a closed-end fund established in 1972, primarily focused on delivering a high level of current income while maintaining prudent investment risk through a diversified portfolio of mainly investment-grade debt securities. These include government securities, bank debt, commercial paper, and cash equivalents, with secondary investments in privately placed debt and select equity securities for potential capital appreciation. The fund employs team-based management and robust credit research to pinpoint attractively priced fixed-income opportunities, featuring an effective duration of approximately 6.77 years, weighted average life of 11.19 years, and sector allocations led by banking (24.46%), energy (8.76%), and insurance (7.68%). It distributes income monthly, typically around $0.0525 per share, and maintains total net assets near $126 million. As a closed-end structure, its shares often trade at a discount to net asset value, reflecting market dynamics in the taxable investment-grade fixed-income space.
