ITEM 2.02 Results of Operations and Financial Condition

The information contained in this Form 8‑K shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

On October 26, 2017, VASCO Data Security International, Inc. (VASCO) issued a press release providing a financial update for the third quarter and nine months ended September 30, 2017.  The full text of the press release is attached as Exhibit 99.1 to this Current Report on Form 8‑K.

The press release contained non-GAAP financial measures within the meaning of the Securities and Exchange Commission’s Regulation G.  For purposes of Regulation G, a non-GAAP financial measure is a numerical measure of a registrant’s historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the issuer; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented.

The press release contained a reference to EBITDA and provided a reconciliation of net income to EBITDA.  EBITDA, which is earnings before interest, taxes, depreciation and amortization, is computed by adding back net interest expense, income tax expense, depreciation expense, and amortization expense to net income as reported.

The press release contained a reference to Non-GAAP Net Income and provided a reconciliation of net income to Non-GAAP Net Income. Non-GAAP Net Income is computed by adding back long term compensation expense, amortization of purchased intangible assets, and the corresponding tax impact of the two adjustments to net income.

The press release also contained a reference to Non-GAAP Diluted Earnings Per Share and provided a reconciliation of diluted earnings per share to Non-GAAP Diluted Earnings Per Share.  Non-GAAP Diluted Earnings Per Share is the same as Non-GAAP Net Income described above on a fully diluted per share basis.
