TPG Mortgage Investment Trust is a residential mortgage REIT that acquires and securitizes newly-originated residential mortgage loans in the non-agency U.S. mortgage market, including non-conforming qualified and non-qualified mortgages, agency-eligible loans, and home equity loans, as well as agency mortgage-backed securities guaranteed by government-sponsored enterprises. The Company generates revenue primarily through net interest income from its investment portfolio, fair value changes in investments and hedges, and mortgage banking income from its majority-owned mortgage originator and servicer. The Company finances its assets through short-term repurchase agreements and its parent TPG's proprietary securitization platform, employs leverage to enhance returns, and uses derivatives to manage interest rate risk, while operating as a REIT that distributes at least 90% of taxable income to shareholders.
