Arne M. Sorenson, president and chief executive officer of Marriott International, said, "2017 was a terrific year. We made great progress on the integration of Starwood, capturing significant property and corporate overhead cost synergies while also increasing our worldwide RevPAR index. We entered into a joint venture with Alibaba to better engage with Chinese customers and invested in PlacePass to provide our guests with even more experiential travel opportunities. We also signed strategic new credit card agreements that will allow us to strengthen our customer offerings, generate significant benefits for our owners and franchisees, and provide higher branding fees for Marriott".
"In the first full year after acquiring Starwood, solid RevPAR gains, strong rooms growth, and property-level margin improvement combined to deliver record fee revenue. With our owners and franchisees, we opened over 76,000 rooms during the year to reach over 1.25 million rooms. Significant new signings drove our development pipeline to a record 460,000 rooms, over 80 percent of which are in the upscale, upper upscale or luxury tiers. Compared to combined full year 2016 results, worldwide systemwide RevPAR rose 3 percent during the year; adjusted operating income increased 13 percent; and adjusted earnings per share increased 32 percent. We returned $3.5 billion to shareholders in share repurchases and dividends during the year.
"In 2018, we anticipate our number of rooms will increase roughly 7 percent gross, while rooms deletions should total 1 to 1.5 percent during the year. We also continue to expect global RevPAR will increase by 1 to 3 percent. As a result of U.S. tax reform, we expect our effective tax rate in 2018 will decline meaningfully to approximately 22 percent. Not including incremental asset sales, we expect to return roughly $2.5 billion to shareholders in share repurchases and dividends in 2018.
"Our company was founded on the principle of taking care of our associates, so they take care of our guests, who then keep coming back. For 2018, we plan to invest in our workforce by offering an additional one-time contribution to the Marriott International retirement savings plans. Structured as a $5-to-$1 company match of up to $1,000, the vast majority of participating associates should receive this incremental company contribution. This contribution will be available to eligible associates at company-operated hotels, as well as those in corporate and regional offices, in the U.S. We also expect to invest in global associate support programs."
