Passage: The Nauruan economy peaked in the mid-1970s to early-1980s, when the phosphate deposits that originate from the droppings of sea birds began to be depleted. At its peak, Nauru's GDP per capita was estimated to be US$50,000, second only to Saudi Arabia. There are few other resources, and most necessities are imported. Small-scale mining is still conducted by RONPhos, formerly known as the Nauru Phosphate Corporation. The government places a percentage of RONPhos's earnings into the Nauru Phosphate Royalties Trust. The trust manages long-term investments, which were intended to support the citizens once the phosphate reserves were exhausted.Because of mismanagement, the trust's fixed and current assets were reduced considerably and may never fully recover. The failed investments included financing Leonardo the Musical in 1993. The Mercure Hotel in Sydney and Nauru House in Melbourne were sold in 2004 to finance debts and Air Nauru's only Boeing 737 was repossessed in December 2005. Normal air service resumed after the aircraft was replaced with a Boeing 737–300 airliner in June 2006. In 2005, the corporation sold its remaining real estate in Melbourne, the vacant Savoy Tavern site, for $7.5 million.The value of the trust is estimated to have shrunk from A$1.3 billion in 1991 to A$138 million in 2002. Nauru currently lacks money to perform many of the basic functions of government; for example, the National Bank of Nauru is insolvent. The CIA World Factbook estimated a GDP per capita of US$5,000 in 2005. The Asian Development Bank 2007 economic report on Nauru estimated GDP per capita at US$2,400 to US$2,715. The United Nations (2013) estimates the GDP per capita to 15,211 and ranks it 51 on its GDP per capita country list.
