Our investments in the common stock of other publicly traded mortgage REITs expose us to incremental risks and costs and may adversely affect our financial condition and results of operations.
The mortgage REITs in which we invest primarily invest in agency MBS on a leveraged basis and utilize short-term repurchase agreements as their primary source of funding and, therefore, are exposed to similar risk factors as those described herein. In addition, our investments in other mortgage REITs expose us to incremental risks and costs due to our lack of control, lack of transparency into their underlying investment portfolios and business operations, stock market volatility and additional management fees, which could adversely affect our financial condition and results of operations.
Our investments are recorded at fair value, and quoted prices or observable inputs may not be available to determine such value, resulting in the use of significant unobservable inputs to determine value.
The values of our investments may not be readily determinable or ultimately realizable. We measure the fair value of our investments quarterly, in accordance with guidance set forth in FASB Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures. Ultimate realization of the value of an asset depends to a great extent on economic and other conditions that are beyond the control of our Manager, our Company or our Board of Directors. Further, fair value is only an estimate based on good faith judgment of the price at which an investment can be sold since market prices of investments can only be determined by negotiation between a willing buyer and seller. If we were to liquidate a particular asset, the realized value may be more than or less than the amount at which such asset is valued. Accordingly, the value of our common stock could be adversely affected by our determinations regarding the fair value of our investments, whether in the applicable period or in the future. Additionally, such valuations may fluctuate over short periods of time.
Our Manager's determination of the fair value of our investments includes inputs provided by third-party dealers and pricing services. Valuations of certain investments in which we invest may be difficult to obtain or unreliable. In general, dealers and pricing services heavily disclaim their valuations. Dealers may claim to furnish valuations only as an accommodation and without special compensation, and so they may disclaim any and all liability for any direct, incidental, or consequential damages arising out of any inaccuracy or incompleteness in valuations, including any act of negligence or breach of any warranty. Depending on the complexity and illiquidity of a security, valuations of the same security can vary substantially from one dealer or pricing service to another. Therefore, our results of operations for a given period could be adversely affected if our determinations regarding the fair market value of these investments are materially different than the values that we ultimately realize upon their disposal.
The federal conservatorship of Fannie Mae and Freddie Mac and related efforts, along with any changes in laws and regulations affecting the relationship between these agencies and the U.S. Government, may adversely affect our business.
The payments of principal and interest we receive on the agency securities in which we may invest are guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae. Fannie Mae and Freddie Mac are GSEs, but their guarantees are not backed by the full faith and credit of the United States. Ginnie Mae is part of a U.S. Government agency and its guarantees are backed by the full faith and credit of the United States.
In response to general market instability and, more specifically, the financial conditions of Fannie Mae and Freddie Mac, in July 2008, the Housing and Economic Recovery Act of 2008, or HERA, established FHFA as the new regulator for Fannie Mae and Freddie Mac. In September 2008, the U.S. Treasury, the FHFA and the U.S. Federal Reserve announced a comprehensive action plan to help stabilize the financial markets, support the availability of mortgage financing and protect taxpayers. Under this plan, among other things, the FHFA was appointed as conservator of both Fannie Mae and Freddie Mac, allowing the FHFA to control the actions of the two GSEs, without forcing them to liquidate, which would be the case under receivership. Importantly, the primary focus of the plan was to increase the availability of mortgage financing by allowing these GSEs to continue to grow their guarantee business without limit, while limiting the size of their retained mortgage and agency security portfolios and requiring that these portfolios be reduced over time.
Although the U.S. Government has committed to support the positive net worth of Fannie Mae and Freddie Mac, the two GSEs could default on their guarantee obligations, which would materially and adversely affect the value of our agency securities. Accordingly, if these government actions are inadequate and the GSEs continue to suffer losses or cease to exist, our business, operations and financial condition could be materially and adversely affected.
In addition, the future roles of Fannie Mae and Freddie Mac could be significantly reduced and the nature of their guarantee obligations could be considerably limited relative to historical measurements. Any such changes to the nature of their guarantee obligations could re-define what constitutes an agency security and could have broad adverse implications for the market and our business, operations and financial condition.
We could be negatively affected in a number of ways depending on the manner in which related events unfold for Fannie Mae and Freddie Mac. We rely on our agency securities as collateral for our financings. Any decline in the value of agency
