  • Installment Sales

    The Regulation About Installment Sales ( "The Regulation" ) entered into force by being published in the Official Gazette on 14 th  January 2015. Although the title is 'installment sales'; the main subject of the Regulation is financial leasing agreements. It is important to be careful not to confuse the installment sales with the prepaid sales. In prepaid sales the buyer have the possession of the sold movable property after completing the payment. However in installment sales the buyer gets the property immediately and then makes the payment. Moreover the sales made by credit cards are not the subject of this Regulation.
  • Protection of Creditors and Employees and Personal Liabilities of Shareholders in Mergers

    Synergies and increase in the assets of the merging companies are aimed at mergers. However, a merger may at the same time result in the increase of the liabilities of the merging companies. Further, in some cases the financial standing of the absorbed company in a merger may not even show positive figures thus such a merger may present a potential risk on the creditors of especially the surviving company. Due to the fact that creditors of the merging entities do not have a veto right against a merger, there arises the need for a specific protection tool for the creditors. A merger may also negatively affect the employees of the merging entities, again especially the ones of the absorbed company. On the other hand, "over-protection" may defeat the purpose of the merger concept so a fairly balanced protection mechanics is essential. This article focuses on the means of protection of creditors and employees, and personal liabilities of shareholders in mergers, as regulated by the Turkish Commercial Code ("TCC").
