Japanese private equity firm Advantage Partners has hired Citigroup to find a buyer for its controlling stake in GTA, a provider of fixed and mobile telephony, internet access and digital television services in Guam, reports Reuters, citing people with direct knowledge of the matter. The sale of GTA could raise over USD300 million, according to the unnamed sources. TeleGeography’s GlobalComms Database states that GTA was privatised in January 2005 when the government sold its shareholding to TeleGuam Holdings, a subsidiary of California-based Shamrock Capital Advisors. In a deal first announced in November 2010, the Guam Public Utilities Commission (PUC) approved the sale of GTA TeleGuam to funds served by Advantage Partners in February 2011. The transaction was finalised the following June after receiving approval from the US telecom regulator, the Federal Communications Commission (FCC). Terms of the deal were not disclosed.
