The purchases were made from Marinsa, CSAV's primary stockholder, through Quinenco, the company through which Luksik controls its investments.
Luksic said it will ask shareholders to raise an additional $500 million in capital. CSAV warned last month of "negative results" for the first quarter and said the company would seek a $500 million capital increase and to sell up to 49 percent of the company's ports and shipping services subsidiary.
CSAV has expanded rapidly since receiving a cash bailout of $770 million in 2009 from German shipowners, including Peter Dohle, which took a minority stake in the company in exchange for lower charter rates.
The company has jumped from 16th to seventh in vessel capacity measured in 20-foot-equivalent units.
CSAV swung to a full-year profit of $170.8 million in 2010 from a loss of $656.4 million in 2009 as operating revenue rose 79.7 percent to $5.45 million.
