Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are exposed to the impact of changes in commodity prices, interest rates and foreign currency exchange rates.

Commodity Prices

Our net sales, cash flows and estimates of future cash flows related to nitrogen-based fertilizers are sensitive to changes in fertilizer prices as well as changes in the prices of natural gas and other raw materials unless these costs have been fixed or hedged. A $1.00 per MMBtu change in the price of natural gas would change the cost to produce a ton of ammonia, granular urea, UAN (32%) and AN by approximately $32, $22, $14 and $15, respectively.

Natural gas is the largest and most volatile component of the manufacturing cost for nitrogen-based fertilizers. We manage the risk of changes in natural gas prices primarily with the use of derivative financial instruments covering periods through December 2018. The derivative instruments that we use are primarily natural gas fixed price swaps and natural gas options. These derivatives settle using primarily NYMEX futures price indexes, which represent the basis for fair value at any given time. The contracts represent anticipated natural gas needs for future periods and settlements are scheduled to coincide with anticipated natural gas purchases during those future periods.

As of December 31, 2016 and 2015, we had open derivative contracts for 183.0 million MMBtus and 431.5 million MMBtus, respectively. A $1.00 per MMBtu increase in the forward curve prices of natural gas as of December 31, 2016 would result in a favorable change in the fair value of these derivative positions of $169 million, and a $1.00 per MMBtu decrease in the forward curve prices of natural gas would change their fair value unfavorably by $169 million.

From time to time we may purchase nitrogen products on the open market to augment or replace production at our facilities.

Interest Rates

As of December 31, 2016, we had eight series of senior notes totaling $5.85 billion of principal outstanding with maturity dates of May 1, 2018, May 1, 2020, December 1, 2021, June 1, 2023, December 1, 2026, March 15, 2034, June 1, 2043 and March 15, 2044. The senior notes have fixed interest rates. As of December 31, 2016, the carrying value and fair value of our senior notes was approximately $5.78 billion and $5.51 billion, respectively.

Borrowings under the Revolving Credit Agreement bear current market rates of interest and we are subject to interest rate risk on such borrowings. Maximum borrowings during 2016 and 2015 were $150 million and $367 million, respectively. There were no borrowings outstanding as of December 31, 2016 or December 31, 2015.

Upon the termination of the Combination Agreement on May 22, 2016, the lenders’ commitments under the Bridge Credit Agreement terminated automatically. There were no borrowings under the Bridge Credit Agreement.

Foreign Currency Exchange Rates

Since the fourth quarter of 2012, we have entered into euro/U.S. dollar derivative hedging transactions related to the euro-denominated construction costs associated with our capacity expansion projects at our Donaldsonville, Louisiana and Port Neal, Iowa facilities. As of December 31, 2015, the notional amount of our open foreign currency forward contracts was €89 million. All of these foreign currency derivatives settled in 2016.

We are directly exposed to changes in the value of the Canadian dollar, the British pound and the Euro. Outside of the transactions mentioned above, we do not maintain any exchange rate derivatives or hedges related to these currencies.
