Residential mortgages are generally divided into two primary subdivisions: Mortgages insured by federal agencies and those without agency backing. Hybrid mortgage REITs hold both types of RMBS. Non-agency RMBSs are generally higher yielding than agency RMBSs, but also present the risk of borrower default. Both have their place in income portfolios. A good deal of non-agency paper is rated as junk, while agency-backed paper is gets a rating commensurate with the nation's implied guarantee.
Within the world of non-agency mortgages, there are four main categories: Prime, Alternative-A (Alt-A), Option Adjustable Rate Mortgages (Option ARMs) and Subprime. The subprime RMBSs imploded in 2007 and 2008, with scattered defaults across all other types subsequently occurring. Many initially estimated that the last significant wave of defaults would hit the Alt-A and Option ARM categories when interest rates begin to rise.
Most hybrid mREITs now hold large and growing positions in agency RMBSs. Many diversified into agency-backed paper in order to reduce income-stream and portfolio value volatility. Additionally, since the Subprime crisis, few non-agency mortgages have been issued, and the lack of non-agency paper has forced many hybrid mREITs to accumulate larger positions of agency paper out of necessity. Adding agency paper also often includes increasing leverage.
Below are recent performance rates and current annual dividend rates for five mortgage REITs that are largely invested in non-agency RMBS paper: Chimera Investment (CIM), Invesco Mortgage Capital (IVR), MFA Financial (MFA), Redwood Trust (RWT) and Two Harbors Investment TIWO).
Non-agency RMBS paper valuations declined significantly during 2011, bringing down most of these hybrid mREITs. So far in 2012, after several months of declining prices, these REITs averaged 13.26% equity appreciation. Several of these mREITs just went ex-dividend or are going ex-dividend in the coming days.
Under the current tax laws, mREIT dividends are taxed as ordinary income, and not at the lower corporate dividend rate. Since mREIT dividends are taxed as income, they are considered substantially better performing investments when held within tax deferred or exempt accounts.
Mortgage REITs continue to be one of the highest-yielding options available to income-oriented investors. Nonetheless, due to their significant risk profile, exposure to non-agency RBMS should be limited to a reasonable percentage of a high-risk portfolio, based upon an investor's total risk profile, time horizon, income requirements and total portfolio of investments.
