Subprime mortgages “Subprime" refers to loans that do not meet Fannie Mae or Freddie Mac guidelines. This is generally due to one or a combination of factors, including credit status of the borrower, income and job history, and income to mortgage payment ratio.Fannie MaeFreddie Mac Types: ARMs An interest-only loan A stated income loan is a mortgage where the lender does not verify the borrower's income (sometimes called "liar loans“)

An Example of Subprime Mortgage Would you like a mortgage that lends you more than the value of your house? Would you like it structured so that your first payments are extra low? If the mortgage weren't structured that way, would you be unable to afford the payments? Are you convinced that real estate prices will continue to rise? Do you have a poor credit history? Congratulations if you answered "Yes" to most or all of those questions! You're an ideal target for a subprime mortgage lender. Adapted from cbc.ca

Asset Quality 17 June Satyajit Das Under US accounting rules, asset must be classified into: Level 1 (Mark-To-Market) - liquid assets or instruments that are actively traded. Level 2 (Mark-To-Model) - instruments that cannot be priced based on trade prices but are valued using observable inputs. Level 3 (Mark-To-Make Believe or Mark-to-Myself) - the asset or liability cannot be priced using observable inputs and requires the use of modeling techniques and substantially subjective assumptions. Asset quality uncertainty can be gauged by looking at bank’s Level 3 assets
