Thanks to strong cash flow generation, Cboe has improved its financial risk profile, and we project S&P Global Ratings adjusted debt to EBITDA of 1.4x and funds from operations to debt of 54% at the end of 2018. Profitability also improved, thanks notably to the successful integration of Bats Global Markets (Bats), but the company remains reliant on its two flagship products--VIX futures and options and SPX options--in our view. We raised the long-term rating on Cboe to 'A-'. Our stable outlook reflects our expectation that Cboe will keep debt to EBITDA lower than 1.5x and funds from operations to debt higher than 50% over the next two years.
