Lululemon has filed paperwork that will enable founder Chip Wilson to sell his remaining $1.3 billion stake in the Vancouver-based maker of yoga pants and other athletic apparel. The move follows last year's decision by the firm to allow Wilson to sell an equal number of shares amid a power struggle and Wilson's decision earlier this year to vacate his seat on the board following a squabble over governance reforms. Wilson is currently focusing on expanding a new clothing line, Kit & Ace — set to soon debut in Australia, Britain and Japan — and it is suspected that the money, were a sale to occur, would be used to fund his fledgling company.
