Pakistan Steel Mills. Panama Panama Canal Philippines In the Philippines, state-owned enterprises are known as government-owned and controlled corporations (GOCCs). They can range from the Social Security System (SSS) and the Philippine Coconut Authority with no counterparts in the private sector, to Land Bank of the Philippines, a wholly government-owned bank that competes with private banks. A number of GOCCs, especially those that were nationalized by president Ferdinand Marcos during his time as the leader of the Fourth Republic of the Philippines, were returned to the private sector by the end of the 20th and the beginning of the 21st century, as with Philippine Airlines (PAL), Philippine Long Distance Telephone Company (PLDT), Philippine National Bank (PNB), and ABS-CBN Corporation (where the frequencies and facilities used by Banahaw Broadcasting Corporation (BBC) were returned to ABS-CBN in 1986 and the ABS-CBN Broadcasting Center were fully recovered by ABS-CBN from People's Television Network (PTV) in 1992), or fully or partially privatized as with National Power Corporation (NPC/NAPOCOR), National Transmission Corporation (TransCo), and Philippine National Construction Corporation (PNCC).
