McDonald's Corporation announced today that global comparable sales increased 7.7 percent in May and 7.0 percent year-to-date. Systemwide sales for McDonald's worldwide restaurants increased 16.0 percent in May, or 9.1 percent in constant currencies.

    U.S. comparable sales rose 4.3 percent in May, on top of a strong increase last year. McDonald's robust breakfast line-up, new menu items, including the recently launched Southern Style Chicken biscuit and sandwich, and emphasis on everyday affordability continue to bring more customers to McDonald's.

    Momentum continued in Europe as comparable sales increased 9.6 percent for the month led by the U.K., France, and Russia. The ongoing appeal of locally relevant premium products, classic menu favorites, and value options available across Europe contributed to this month's results.

    Comparable sales for Asia/Pacific, Middle East, and Africa were up 9.7 percent in May, driven primarily by strong performance in Australia and many other markets. Throughout the segment, branded value offerings, breakfast, and extended operating hours are giving customers more reasons to visit McDonald's.

    McDonald's expects the effective tax rate for the second quarter and full year to be approximately 29 percent to 31 percent.
