financial markets, which may result in increased delinquencies on mortgage loans, the government-sponsored entities cost of capital, general economic conditions and the relative interest rates on fixed and adjustable rate loans, which could lead to an acceleration of the payment of the related principal. Additionally, changes in the government-sponsored entities' decisions as to when to repurchase delinquent loans can materially impact prepayment rates.
In addition, the introduction of new government programs could increase the availability of mortgage credit to a large number of homeowners in the United States, which could impact the prepayment rates for the entire mortgage securities market, and in particular for Fannie Mae and Freddie Mac agency securities. These new programs or changes to existing programs could cause substantial uncertainty around the magnitude of changes in prepayment speeds. To the extent that actual prepayment speeds differ from our expectations, it could adversely affect our operating results.
Market conditions may disrupt the historical relationship between interest rate changes and prepayment trends, which may make it more difficult for our Manager to analyze our investment portfolio.
Our success depends, in part, on our Manager's ability to analyze the relationship of changing interest rates on prepayments of the mortgage loans that underlie securities we may own. Changes in interest rates and prepayments affect the market price of the assets that we purchase and any assets that we may hold at a given time. As part of our overall portfolio risk management, our Manager analyzes interest rate changes and prepayment trends separately and collectively to assess their effects on our investment portfolio. In conducting its analysis, our Manager depends on certain assumptions based upon historical trends with respect to the relationship between interest rates and prepayments under normal market conditions. Dislocations in the residential mortgage market and other developments may disrupt the relationship between the way that prepayment trends have historically responded to interest rate changes and, consequently, may negatively impact our Manager's ability to (i) assess the market value of our investment portfolio, (ii) implement our hedging strategies and (iii) implement techniques to reduce our prepayment rate volatility, which could materially adversely affect our financial condition and results of operations.
Actions of the U.S. Government, including the U.S. Congress, U.S. Federal Reserve, U.S. Treasury and other governmental and regulatory bodies may adversely affect our business.
U.S. Government actions may not have a beneficial impact on the financial markets. To the extent the markets do not respond favorably to any such actions or such actions do not function as intended they could have broad adverse market implications and could negatively impact our financial condition and results of operations.
In July 2010, the U.S. Congress enacted the Dodd Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, in part to impose significant investment restrictions and capital requirements on banking entities and other organizations that are significant to U.S. financial markets. For instance, the Dodd-Frank Act imposes significant restrictions on the proprietary trading activities of certain banking entities and subjects other systemically significant organizations regulated by the U.S. Federal Reserve to increased capital requirements and quantitative limits for engaging in such activities. The Dodd-Frank Act also seeks to reform the asset-backed securitization market (including the mortgage-backed securities market) by requiring the retention of a portion of the credit risk inherent in the pool of securitized assets and by imposing additional registration and disclosure requirements. Certain of the new requirements and restrictions exempt agency securities, other government issued or guaranteed securities, or other securities. The Dodd-Frank Act also imposes significant regulatory restrictions on the origination of residential mortgage loans and will impact the formation of new issuances of mortgage-backed securities.
The Dodd-Frank Act has also created a new regulator, the Consumer Financial Protection Bureau, or the CFPB, which now oversees many of the core laws which regulate the mortgage industry, including among others, the Real Estate Settlement Procedures Act and the Truth in Lending Act. While the full impact of the Dodd-Frank Act and the role of the CFPB cannot be assessed until all implementing regulations are released, the Dodd-Frank Act's extensive requirements may have a significant effect on the financial markets. In addition, the Federal Reserve, the Federal Deposit Insurance Corporation and other regulatory entities are currently in the process of implementing new, and possibly more stringent, capital rules on large financial institutions. These new regulatory requirements, when implemented, could adversely affect the availability or terms of financing from our lender counterparties and the availability or terms of mortgage-backed securities, both of which may have an adverse effect on our financial condition and results of operations.
Pursuant to the terms of borrowings under master repurchase agreements, we are subject to margin calls that could result in defaults or force us to sell assets under adverse market conditions or through foreclosure.
We enter into master repurchase agreements with a number of financial institutions. We borrow under these master repurchase agreements to finance the assets for our investment portfolio. Pursuant to the terms of borrowings under our master repurchase agreements, a decline in the value of the collateral may result in our lenders initiating margin calls. A margin call means that the lender requires us to pledge additional collateral to re-establish the ratio of the value of the collateral to the amount of the borrowing. The specific collateral value to borrowing ratio that would trigger a margin call is not set in the master repurchase agreements and
