In this Annual Report on Form 10-K ("Annual Report" and "this report"), the "Company," "we," "us" and "our" refer to United Parcel Service, Inc. ("UPS"). With regard to the Company’s segments, "we," "us" and "our" may also refer to the segment being discussed.

Cautionary Statement About Forward-Looking Statements

This report and our other filings with the Securities and Exchange Commission ("SEC") contain and in the future may contain "forward-looking statements." Statements other than those of current or historical fact, and all statements accompanied by terms such as "will," "believe," "project," "expect," "estimate," "assume," "intend," "anticipate," "target," "plan" and similar terms, are intended to be forward-looking statements.

From time to time, we also include written or oral forward-looking statements in other publicly disclosed materials. Such statements may relate to our intent, belief, forecasts of, or current expectations about our strategic direction, prospects, future results or future events; they do not relate strictly to historical or current facts. Management believes that these forward-looking statements are reasonable as and when made. However, caution should be taken not to place undue reliance on any forward-looking statements because such statements speak only as of the date when made and the future, by its very nature, cannot be predicted with certainty.

Forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations or anticipated results. These risks and uncertainties include, but are not limited to, those described in Part I, "Item 1A. Risk Factors" and elsewhere in this report and may also be described from time to time in our future reports filed with the SEC. You should consider the limitations on, and risks associated with, forward-looking statements and not unduly rely on the accuracy of predictions contained in such forward-looking statements. We do not undertake any obligation to update forward-looking statements to reflect events, circumstances, changes in expectations or the occurrence of unanticipated events after the date of those statements, except as required by law.

The Company routinely posts important information, including news releases, announcements, materials provided or displayed at analyst or investor conferences, and other statements about its business and results of operations, that may be deemed material to investors on the Company’s Investors Relations website at www.investors.ups.com. The Company uses its website as a means of disclosing material, nonpublic information and for complying with the Company’s disclosure obligations under Regulation FD. Investors should monitor the Company’s Investor Relations website in addition to following the Company’s press releases, filings with the SEC, public conference calls and webcasts. We do not incorporate the contents of any website into this or any other report we file with the SEC.
