our ability to operate our business efficiently, to operate and maintain our information technology, technical, accounting and generation monitoring systems, to manage capital expenditures and costs tightly, to manage risks related to international operations, and to generate earnings and cash flows from our asset-based businesses in relation to our debt and other obligations, including in light of the SunEdison Bankruptcy and the ongoing process to establish separate information technology systems; and

The Company disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions, factors, or expectations, new information, data, or methods, future events, or other changes, except as required by law. The foregoing list of factors that might cause results to differ materially from those contemplated in the forward-looking statements should be considered in connection with information regarding risks and uncertainties, which are described in this Quarterly Report on Form 10-Q and the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, as well as additional factors we may describe from time to time in other filings with the SEC.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
We are exposed to several market risks in our normal business activities. Market risk is the potential loss that may result from market changes associated with our business or with an existing or forecasted financial or commodity transaction. The types of market risks we are exposed to include interest rate risk, foreign currency risk, liquidity risk and credit risk. We do not use derivative financial instruments for speculative or trading purposes.
Interest Rate Risk
As of June 30, 2017, our corporate level debt consisted of the Senior Notes (fixed rate). The estimated fair value of our corporate level debt was approximately $855.3 million and the outstanding amount of our corporate level debt was $753.5 million. We estimate that a 100 bps, or 1.0%, increase or decrease in market interest rates for this debt would have decreased or increased the fair value of our long-term debt by $34.0 million.
As of June 30, 2017, our project level debt was at both fixed and variable rates. The estimated fair value of our project level debt was $395.9 million and the outstanding amount of our project level debt was $352.7 million. We have entered into interest rate derivatives to swap certain of our variable rate project level debt to a fixed rate. Although we intend to use hedging strategies to mitigate our exposure to interest rate fluctuations, we may not hedge all of our interest rate risk and, to the extent we enter into interest rate hedges, our hedges may not necessarily have the same duration as the associated indebtedness. Our exposure to interest rate fluctuations will depend on the amount of indebtedness that bears interest at variable rates, the time at which the interest rate is adjusted, the amount of the adjustment, our ability to prepay or refinance variable rate indebtedness when fixed rate debt matures and needs to be refinanced and hedging strategies we may use to reduce the impact of any increases in rates. We estimate that a hypothetical 100 bps, or 1.0%, increase or decrease in our variable interest rates pertaining to interest rate swaps would have decreased or increased the fair value of the swaps respectively by $13.5 million and $12.5 million for the three months ended June 30, 2017.
Foreign Currency Risk
During the six months ended June 30, 2017 and the year ended December 31, 2016, all of our revenues were generated outside of the United States in Brazilian real, Chinese yuan renminbi, Indian rupee, Malaysian ringgit, South African rand, Thai baht, and U.S. dollars, and were translated into the U.S. dollar, which is our reporting currency. The PPAs, O&M agreements, financing agreements and other contractual arrangements in our current portfolio are denominated in Brazilian real, Chinese yuan renminbi, Indian rupee, Malaysian ringgit, South African rand, Thai baht, U.S. dollars and Uruguayan pesos.
We use currency forward contracts in certain instances to mitigate the financial market risks of fluctuations in foreign currency exchange rates. We manage our foreign currency exposures through the use of these currency forward contracts to reduce risks arising from the change in fair value of certain assets and liabilities denominated in foreign currencies. The objective of these practices is to minimize the impact of foreign currency fluctuations on our operating results. We estimate that a hypothetical 100 bps, or 1.0%, increase and decrease in foreign currency exchange rates against the U.S. dollar would have the following impacts on our earnings for the six months ended June 30, 2017:
