Derivative Instruments and Hedging Activities Derivative Instruments and Hedging Activities
 

Exchange rate fluctuations affect a portion of revenues and operating costs that are denominated in foreign currencies, and we use forward currency and currency option contracts to reduce our exposure to certain of these currency price fluctuations. Contracts to sell euros have not been designated as cash flow hedges for accounting purposes, and gains or losses are reported in earnings immediately in other (income) expense. Contracts to purchase Canadian dollars are designated as cash flow hedges for accounting purposes, and we record the gains and losses for the derivatives and premiums paid for option contracts in accumulated other comprehensive income (loss) until we reclassify them into cost of products sold when we recognize the associated underlying operating costs.

We are exposed to fluctuations in market prices of raw materials and energy sources. We may use cash-settled commodity price swaps and options to hedge the market risk associated with the purchase of certain of our raw materials and energy requirements. For input commodities, these derivatives are typically used for a portion of our electricity, iron ore, natural gas, nickel and zinc requirements. Our hedging strategy is to reduce the effect on earnings from the price volatility of these various commodity exposures, including timing differences between when we incur raw material commodity costs and when we receive sales surcharges from our customers based on those raw materials. Independent of any hedging activities, price changes in any of these commodity markets could negatively affect operating costs.

All commodity derivatives are recognized as an asset or liability at fair value. We record the gains and losses and premiums paid for option contracts for commodity derivatives designated as cash flow hedges of forecasted purchases of raw materials and energy sources in accumulated other comprehensive income (loss) and reclassify them into cost of products sold when we recognize earnings for the associated underlying transaction. We record all gains or losses from commodity derivatives for
which hedge accounting treatment has not been elected to earnings immediately in cost of products sold. We have provided no collateral to counterparties under collateral funding arrangements as of June 30, 2018.

Outstanding derivative contracts and the period over which we are hedging our exposure to the volatility in future cash flows are presented below:

We routinely use iron ore derivatives to reduce the volatility of the cost of our iron ore purchases. These derivatives do not qualify for hedge accounting treatment. Therefore, adjustments to mark these derivatives to fair value each period are recognized immediately in our financial results versus being recognized in the period that iron ore purchases affect earnings. For the three and six months ended June 30, 2018, gains (losses) recognized in cost of products sold shown in the table above include $2.1 and $(5.6), for unrealized mark-to-market gains (losses) on iron ore derivatives. Gains (losses) recognized in cost of products sold shown in the table above for unrealized mark-to-market gains (losses) on iron ore derivatives for the corresponding periods in 2017 include (8.4) and $7.9. Not included in the financial results for the three and six months ended June 30, 2018, were realized gains of $9.2 and $11.5 for iron ore derivatives contracts that settled during the period for which we had recognized mark-to-market gains in our financial results in prior quarters, compared to $8.9 and $20.3 for the same periods in 2017.

Gains (losses) before tax expected to be reclassified into cost of products sold within the next twelve months for our existing derivatives that qualify as cash flow hedges for hedge accounting are presented below:
