Sherritt International Corp. reported Wednesday a second-quarter profit of $15.7-million, reduced from year-earlier earnings of $24.4-million after the diversified resource company booked a number of large one-time charges.

Toronto-based Sherritt - a miner, oil and gas producer and power company - said the profit amounted to 5 cents a share, compared with 8 cents in the second-quarter of 2009.

Adjusted earnings, however, came in at a much higher $52.9-million or 18 cents per share. Those excluded $37.2-million worth of one-time items, including a foreign exchange loss of $18.1-million and a $15.3-million provision for income taxes.
