(a) This category includes counterparties with minimum credit ratings of Baa3 assigned by Moodys Investors Service (Moody’s) and BBB- assigned by Standard & Poors Rating
Group, a division of McGraw-Hill Companies, Inc. (Standard & Poors). The five largest counterparty exposures, combined, for this category represented approximately 14% of
the total gross credit exposure.
(b) This category includes counterparties with credit ratings that are below investment grade. The five largest counterparty exposures, combined, for this category represented less
than 1% of the total gross credit exposure.
(c) This category includes counterparties that have not been rated by Moodys or Standard & Poor’s, but are considered investment grade based on DTE Energys evaluation of the
counterpartys creditworthiness. The five largest counterparty exposures, combined, for this category represented approximately 14% of the total gross credit exposure.
(d) This category includes counterparties that have not been rated by Moodys or Standard & Poor’s, and are considered non-investment grade based on DTE Energys evaluation of

We are subject to interest rate risk in connection with the issuance of debt. In order to manage interest costs, we may use treasury locks and interest rate
swap agreements. Our exposure to interest rate risk arises primarily from changes in U.S. Treasury rates, commercial paper rates and London Inter-Bank
Offered Rates (LIBOR). As of December 31, 2014, we had a floating rate debt-to-total debt ratio of approximately 4.6% (excluding securitized debt).

We have foreign currency exchange risk arising from market price fluctuations associated with fixed priced contracts. These contracts are denominated
in Canadian dollars and are primarily for the purchase and sale of natural gas and power as well as for long-term transportation capacity. To limit our
exposure to foreign currency exchange fluctuations, we have entered into a series of foreign currency exchange forward contracts through April 2019.

We performed a sensitivity analysis on the fair values of our commodity contracts, long-term debt obligations and foreign currency exchange forward
contracts. The commodity contracts and foreign currency exchange risk listed below principally relate to our energy marketing and trading activities. The
sensitivity analysis involved increasing and decreasing forward rates at December 31, 2014 and 2013 by a hypothetical 10% and calculating the resulting
change in the fair values.
