A group of Papa Murphy’s take-and-bake pizza franchise owners this month filed a lawsuit against the Vancouver-based parent company in Clark County Superior Court.

In the 11-count complaint, more than 20 franchisees accuse Papa Murphy’s International of failing to disclose accurate information about the financial performance of stores located in Southern and Southeastern states and of collecting more than the contracted amount for advertising. The franchise owners, who together represent more than 60 of the company’s 1,400 stores, also said they were not told that they would need to spend more on advertising in order to achieve sales comparable to stores located in the Pacific Northwest and other parts of the country, said Howard Bundy, a Kirkland attorney representing the franchisees.

When contacted via e-mail on Tuesday, a spokeswoman for Papa Murphy’s International, said the company has not seen the lawsuit.

“At this point, the company has not received or seen a copy of the lawsuit filing and, therefore, cannot comment on its contents at this time,” said the written statement issued by Jessica Liddell, a senior vice president with the Norwalk, Conn.-based public relations firm, ICR.

Papa Murphy’s International, which is headquartered near Westfield Vancouver mall, last month filed an initial public stock offering with the U.S. Securities and Exchange Commission to raise up to $70 million. The company is still in its “quiet period”and is limited as to the amount of information it or related parties can release to the public.
