Western Asset Mortgage Opportunity Fund Inc.

Western Asset Mortgage Opportunity Fund Inc. is a closed-end fixed income mutual fund that invests primarily in mortgage-backed securities in the U.S. fixed income markets. The fund employs proprietary research methodology to construct and manage its portfolio, benchmarking performance against the BofA Merrill Lynch U.S. Floating Rate Home Equity Loan Asset Backed Securities Index. Established in December 2009, the fund is domiciled in New York.

The fund is launched and managed by Legg Mason Partners Fund Advisor, LLC, with co-management provided by Western Asset Management Company and Western Asset Management Company Limited. As a closed-end fund structure, it operates as a publicly traded investment vehicle on the New York Stock Exchange, generating revenue through management fees applied to assets under management and investment returns on its portfolio holdings.

The fund focuses specifically on mortgage-backed securities within the broader fixed income asset class, concentrating its investment activity in this specialized segment rather than diversifying across multiple fixed income categories. As a financial services entity operating in asset management, the fund's scale is measured by assets under management rather than traditional corporate metrics like employee count or revenue figures.
