MR. HENDON SERVED AS A DIRECTOR OF STANDARD LIFE AND CAC, AND AS A MEMBER OF CAC'S ASSET/LIABILITY MANAGEMENT COMMITTEE (THE "ALM
COMMITTEE") FOR THE BENEFIT OF CERTAIN OF THE FUNDS MANAGED BY REGISTRANT. IN THE THIRD QUARTER OF 2008, AS A RESULT OF LOSSES
SUFFERED IN STANDARD LIFE'S FIXED INCOME PORTFOLIO, STANDARD LIFE'S CAPITAL BASE WAS REDUCED TO A LEVEL THAT UNDER INDIANA
DEPARTMENT OF INSURANCE REGULATIONS REQUIRED THE COMMISSIONER TO TAKE ACTION. ON DECEMBER 17, 2008, AFTER FAILING IN EFFORTS TO
RAISE ADDITIONAL CAPITAL, STANDARD LIFE ENTERED INTO A CONSENSUAL ORDER OF REHABILITATION - EFFECTIVELY TURNING CONTROL OF THE
COMPANY OVER TO THE STATE. IN NOVEMBER 2010, ONE WEEK PRIOR TO THE EXPIRATION OF THE INSURANCE POLICY THAT PROVIDED DIRECTORS
AND OFFICERS COVERAGE, THE COMMISSIONER OF THE DEPARTMENT OF INSURANCE SERVED THE DIRECTORS WITH THE LAWSUIT DESCRIBED
HEREIN. MR. HENDON AND THE SUPERINTENDENT OF THE DEPARTMENT OF INSURANCE HAVE EXECUTED A SETTLEMENT TERMINATING THE LITIGATION.
THE SETTLEMENT AGREEMENT PROVIDES FOR THE DISMISSAL OF THE ACTION, WITH PREJUDICE, AND WITHOUT ANY ADMISSION OF LIABILITY ON THE
PART OF MR. HENDON OR ANY OF THE DIRECTORS AND OFFICERS OF STANDARD LIFE AND CAC. THE SETTLEMENT AGREEMENT WAS REACHED ON
BEHALF OF ALL DIRECTORS AND OFFICERS OF STANDARD LIFE AND CAC AND PROVIDES FOR A ONE-TIME SETTLEMENT PAYMENT BY THE INSURANCE
COMPANY, MADE ON BEHALF OF ALL SUCH DIRECTORS AND OFFICERS, INCLUDING MR. HENDON. THE COURT ACCEPTED THE SETTLEMENT AND
DISMISSED THE LITIGATION, WITH PREJUDICE, ON APRIL 5, 2017.
