Visa also has material operational risk as well as large unsecured exposures to financial institutions stemming from its promise to stand behind all transactions processed on its network. The stable outlook on Visa reflects S&P Global Ratings' expectation that the company will maintain solid earnings, high and stable profit margins, and low leverage--without any major disruption at least in the next two years from technological advancement, litigation, or regulation. More specifically, we expect Visa to operate with debt to EBITDA below 1x, as we measure it, and with EBITDA margins near 70%. We could lower our ratings on Visa if its leverage rises significantly, particularly if debt to EBITDA approaches or exceeds 1.5x without a plan to materially reduce it.
