The Company uses foreign currency forward contracts to mitigate the impact of foreign currency fluctuations of certain non-U.S. dollar denominated asset positions, to date primarily cash and accounts receivable (non-designated), as well as to manage foreign currency fluctuation risk related to forecasted transactions (designated). The Company accounts for these instruments as either non-designated or cash flow hedges, respectively. Open contracts are recorded within prepaid expenses and other current assets or accrued liabilities in the consolidated balance sheets. Gains and losses resulting from currency exchange rate movements on non-designated forward contracts are recognized in other income (expense). Any gains or losses from derivatives designated as cash flow hedges are first accumulated in other comprehensive income (AOCI) and then reclassified to revenue when the hedged item impacts the consolidated financial statements.</font></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">During the year ended December 31, 2018, the Company began a hedging strategy to reduce its exposure to foreign currency exchange rate fluctuations for forecasted subscription renewals and new orders in both GBP and Euro. </font><font style="font-family:Arial;font-size:10pt;color:#231f20;">We use sell-forward currency contracts accounted for as cash flow hedges against a designated portion of forecasted </font><font style="font-family:Arial;font-size:10pt;">subscription renewals and new orders</font><font style="font-family:Arial;font-size:10pt;color:#231f20;">. </font><font style="font-family:Arial;font-size:10pt;">Upon executing a hedging contract and quarterly thereafter, the Company assesses hedge effectiveness using regression analysis.

The unrealized gains or losses in AOCI will be reclassified into revenue when the respective hedged transactions affect earnings.
