Set forth below is a summary of such transactions. Controlling Shareholder S&T International Distribution Limited (“S&T”), which is a wholly owned subsidiary of Grande N.A.K.S. Ltd., which is a wholly owned subsidiary of Grande, collectively have the shared power to vote and direct the disposition of 15,243,283 shares, or approximately 56.2%, of the Company’s outstanding common stock. Accordingly, the Company is a “controlled company” as defined in Section 801(a) of the NYSE MKT Company Guide. Related Party Transactions Return of Pledged Collateral to S&T In April 2016, the Company, upon a request made by S&T, considered and agreed to return to S&T the $500,000 of collateral which S&T had paid to the Company in September 2014 as a part of the indemnification agreement between S&T, Grande and the Company pertaining to an Internal Revenue Service challenge of the Company’s March 31, 2010 earnings and profits calculations underlying the taxability of a dividend paid during March 2010 to all of its stockholders, net of the $79,000 in expenses incurred by the Company in defending the IRS challenge. Thusly, on April 29, 2016, the Company paid $421,000 to S&T to effectuate the release of the collateral net of the aforementioned expenses incurred by the Company. From September 30, 2014 through March 31, 2016, this pledged collateral had been recorded by the Company as restricted cash on its balance sheet. Consulting Services Provided to Emerson by one of its Former Directors who is a Current Director of Grande Until such agreement was cancelled by the Company effective November 7, 2013, Mr. Eduard Will, a former director of Emerson and a current director of Grande, was paid consulting fees by the Company for work performed by Mr. Will related to a lawsuit that the Company settled in December 2013 and merger and acquisition research. Mr. Will was not re-elected to serve as a director of the Company at the Company’s 2013 Annual Meeting of Stockholders held on November 7, 2013. Accordingly, Mr. Will was no longer a director of the Company or a related party to the Company from November 7, 2013 until his appointment as a director of Grande on February 19, 2016, at which time Mr. Will is once again a related party to the Company. During March 2016, Emerson accrued $12,000 in consulting fees and expense reimbursements for consulting work invoiced to the Company and expenses incurred by Mr. Will as a director of the Company during the period September 2013 through November 2013, and which the Company paid to Mr. Will in April 2016.
