Nigeria's acting President Goodluck Jonathan has sworn in members of his new cabinet.
A senior executive at the investment bank Goldman Sachs, Olusegun Aganga, has been appointed finance minister.
Thirteen members of the new cabinet are from the dissolved government, Reuters reports.
Mr Jonathan has placed former Mines Minister Deziani Allison-Madueke in charge of the country's oil ministry, a key post in the oil-rich state.
Mr Jonathan has outlined his main priorities as electoral reforms, security in the oil-producing Niger Delta, providing a more reliable power supply and fighting corruption.
In March, Mr Jonathan dissolved the entire cabinet and made new nominations, most of which were accepted by Nigeria's senate last week.
The new cabinet is expected to remain in place until elections due next year.
These are due in April but could be held in January.
President Umaru Yar'Adua has not been seen in public since he fell ill in November 2009.
