item 7a .
quantitative and qualitative disclosure about market risks market risk we are exposed to market risks primarily from changes in interest rates and foreign currency exchange rates .
we use certain derivative financial instruments , including interest rate swaps and foreign currency forward exchange contracts , to manage interest rate and foreign currency risk .
we do not use derivatives for trading purposes , to generate income or to engage in speculative activity .
interest rate risk in addition to existing cash balances and cash provided by operating activities , we use fixed rate and variable rate debt to finance our operations .
we are exposed to interest rate risk on these debt obligations and related interest rate swaps .
the notes ( as defined in note 13 to the consolidated financial statements ) represent substantially all of our fixed-rate long-term debt obligations .
the carrying value of the notes was $ 1950.0 million as of december 31 , 2012 .
the fair value of the notes was approximately $ 2138.2 million as of december 31 , 2012 .
the potential reduction in fair value of the notes from a hypothetical 10 percent increase in market interest rates would not be material to the overall fair value of the debt .
our floating rate long-term debt obligations principally relate to borrowings under the fis credit agreement ( as also defined in note 13 to the consolidated financial statements ) .
an increase of 100 basis points in the libor rate would increase our annual debt service under the fis credit agreement , after we include the impact of our interest rate swaps , by $ 9.3 million ( based on principal amounts outstanding as of december 31 , 2012 ) .
we performed the foregoing sensitivity analysis based on the principal amount of our floating rate debt as of december 31 , 2012 , less the principal amount of such debt that was then subject to an interest rate swap converting such debt into fixed rate debt .
this sensitivity analysis is based solely on .
