From what I gather - it's 2010 to Q1 2013 for SKTO, and for Medical Greens from Q1 to Q2 2013. "Current periods to date" would only encompass March 31, 2013 ending as the PR was on June 27, 2013 which is before Q2 would have closed and thus not filed = not current.

SK3 Group, Inc. (OTC Pink: SKTO) announces that it has engaged the firm of L.L. Bradford Company, LLC to audit the financial statements of SKTO for the years ended 2010 through and 2012 and the current periods to date, and of its subsidiary, Medical Greens, Inc. through June 30, 2013.
