Within: Tax

Baker McKenzie Abogados, S.C.’s ‘excellent’ tax practice is particularly known for transfer pricing and tax disputes, both areas in which the team is ‘very strong’, say peers. For one client, the team is the ‘first choice, because the lawyers never put the company at risk. They offer a great service; they are very capable and knowledgeable of the industry. Their response times are good, and they are very professional’. The practice also stands out since, with 70 lawyers (including 15 partners) operating from five offices, it arguably offers unrivalled national coverage. Headline work saw practice head Luis Carbajo assist KBR with the design and implementation of a legal strategy to reach an out-of-court settlement regarding a tax inspection representing tax liabilities of approximately $209m. In another ongoing highlight case, Jorge Narváez and Roberto Cardona advised Adidas de México on a negotiation with the tax authorities regarding a transfer pricing adjustment following a disallowed deduction for income tax purposes of royalty and advertising expenses amounting to $20m. Narváez heads the firm’s Global Tax Dispute Resolution Group and handles tax litigation, transfer pricing and corporate reorganisation; Cardona has a ‘strong litigation background’ which he combines with tax planning. The two lawyers were supported by Carlos Linares who has ‘excellent transfer pricing skills and great experience’; he heads the firm’s regional transfer-pricing practice (and can draw on the expertise of the firm’s principal economist and TP specialist Moisés Curiel). Key figure Héctor Reyes (acting in conjunction with Cardona) assisted Walt Disney Studios Sony Pictures Releasing de México with the implementation of a legal strategy to recover a significant proportion of the single rate business tax ("IETU") paid during the fiscal years 2008 to 2013. Reyes also has extensive experience in international tax planning, M&A and cross-border transactions and inter-company pricing. Further support comes from Ulises Castilla, who assisted Carbajo with the KBR mandate; a former head of contentious matters at the SAT’s department for major contributors, he handles tax strategy and litigation. Victor Morales-Chavez was made partner in early 2018; his practice focuses on corporate taxes, non-resident taxation, international tax treaties and general tax planning; and José P Barnola Jr, a partner at the firm’s Caracas office, is currently working out of Mexico City and will do so for two years as part of the firm’s mobility programme.

  • The New Turkish Code of Obligations: Important Changes for Leases of Residential & Business Premises

    For decades, the primary Turkish laws governing leases of residential and business premises have been the Law on Leasing Real Property dated May 27, 1955 (the “Lease Law”) and the Turkish Code of Obligations No. 818 dated April 22, 1926 (the “Obligations Code”). Both of these laws, however, will be repealed and replaced with the new Turkish Code of Obligations No. 6098 dated January 11, 2011 (the “New Obligations Code”), which will enter into force on July 7, 2012.

  • Notorious Marks

    Notorious marks or the declaration thereof, has always been an issue widely discussed in Mexico by the IP legal community. This is so because provisions of the Paris Convention dealing with this topic have for a long time been uses as an effort to cancel or nullify trademarks registered by Mexican authorities without really making an extensive evaluation of proposed denominations and without examining in depth if such marks may be potentially affecting rights acquired by third parties elsewhere. So, a specific regulation and legal frame that at least tries to resolve this issue is always a good start in the right direction.

    By Ignacio Dominguez Torrado Uhthoff, Gomez Vega & Uhthoff, S.C. Why a new value? Is Mexico avoiding the economic fallout that the world may be facing? In Mexico franchises are worth more? Is Mexico not a country that the global economic standstill is or will affect? The answer is, not really. Are Franchises in Mexico currently experiencing a boom? Perhaps. Are Franchises becoming an important aspect in Mexican economy? Certainly.

    Advertising in Mexico is governed by multiple bodies of law including for at least seven Federal Laws, five Regulations also of Federal application, a number of the so-called Mexican Official Standards (NOM's) and certain other laws and regulations applicable into specific States within the Republic of Mexico. All of them are focusing to establish the form and manners for producing and communicating advertising of products and services in Mexico.

    It has been well publicized in the Mexican media over the last few months that the General Customs Administration (AGA) and the Mexican Institute of Industrial Property (IMPI) are planning to launch a customs trademark registry, as a short-term solution to increase protection for trademark owners against the import of infringing and counterfeit products.

    The evolution in the protection and enforcement of IP rights has also reached the Mexican practice. The traditional ways of defending a registered trademark on a non use contentious procedure have developed.
