In the wake of several executive-level changes at Kobo over the past few months, the Toronto-based e-reading company has cut more than 60 positions at its headquarters. The company employs 500 people worldwide.

While it is unclear which particular departments or positions have been affected, Kobo public relations manager René d’Entremont released a statement to media saying, “As part of this change, teams have been restructured and optimized; redeploying employees to best use their skills to support the company’s core goal of providing the best global eReading experience. All our offices will continue to operate as usual, with a mandate to grow the business in each of our territories.”

D’Entremont notes that the changes come “as part of an ongoing review that began with shifts in executive leadership this past March.” In early February, Kobo announced that Takahito “Taka” Aiki, an executive from Rakuten, the Japanese e-commerce company that acquired Kobo in early 2012, would replace founding CEO Michael Serbinis. Longtime executive Michael Tamblyn was promoted to president in early April.

D’Entremont adds, “While these decisions are never easy, we believe that we have the structure that puts us in the best position possible to aggressively compete in an ever-challenging global marketplace. By ensuring the Kobo team is lean and agile, we will be able to strengthen our business position and continue our trajectory of global growth.”
