If the forecasted transaction is deemed probable to not occur, the derivative gain or loss reported in AOCI shall be reclassified into earnings immediately. During the first quarter of 2017, we terminated two interest rate swap contracts designated as cash flow hedges of forecasted transactions. At the time of termination, we determined that the underlying hedged forecasted transactions were still probable of occurring. These transactions are reevaluated on a monthly basis thereafter, to determine if the hedged forecasted transactions are still probable of occurring. If at a subsequent evaluation, it is determined that the transactions will not occur, any related gains or losses recorded in AOCI are immediately recognized in earnings.</font></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The existing gain in AOCI related to the terminated interest rate swap contracts will be reclassified into earnings through straight-line accretion in the same periods the hedged forecasted transaction affects earnings. </font></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Further information on our derivative instruments and hedging activities is included in “Note 10 - Derivative Financial Instruments and Hedging Activities.”</font></div></div>
