Banking and finance

Within: Banking and finance

The consensus among Marval, O'Farrell & Mairal’s clients is that its banking team is ‘the most reliable in Argentina’, due its ‘deep and experienced bench’ and ‘reassuringly well-informed partners’. The group packs a punch across the full spread of syndicated loans, structured finance, debt capital markets and project finance, and it also has formidable supplementary expertise in banking M&A and regulatory matters. Among the names to note, department head Santiago Carregal is an ‘instantly recognisable name for banking deals’; he recently advised the international purchasers (UBS and Itaú Securities) and the local purchasers (Balanz, Industrial Valores and Puente H’nos) on the local aspects of Raghsa’s $100m notes offering. Other senior members of the team include the ‘very experienced and creative’ Roberto Silva Jr and department coordinator Gabriel Matarasso; the latter acted as local counsel to International Finance Corporation (IFC), Inter-American Investment Corporation (IIC) and Inter-American Development Bank (IDB) on a $410m project financing provided to Renova. Matarasso also teamed up with Juan Diehl Moreno and Diego Chighizola to act for the banks on a $750m acquisition financing granted to Cablevisión Holding to support its purchase of a stake in Telecom Argentina. Among the banking group’s company-side work, Fernando Hernández, Hernán Slemenson and M&A specialist Pablo Viñals Blake assisted Adecoagro on its $500m international bond offering. The practice also draws on the experience of ‘banking expertCecilia Mairal and senior associate Francisco Abeal, who is a ‘lawyer to watch’.
