The company forecast total revenues in Q1 to be around $250M, assuming year-over-year royalty growth based on similar trends and given the positive outlook for license revenues.

However, assuming the macroeconomic situation does not deteriorate significantly, we expect group dollar revenues for the full-year to be at least in line with current market expectations."
