All shares entitled to vote and represented by properly submitted proxies received before the polls are closed at the Annual Meeting, and not revoked or superseded, will be voted at the Annual Meeting in accordance with the instructions indicated on those proxies.YOUR VOTE IS VERY IMPORTANT.

If You Do Not Specify How You Want Your Shares Voted

As a stockholder of record, if you submit a signed proxy card or submit your proxy by telephone or Internet and do not specify how you want your shares voted, the proxy holder will vote your shares:

vote on the ratification of the selection of Ernst & Young LLP as our independent registered public accountants. Brokers, however, do not have discretionary authority to vote on the election of directors to serve on our Board, the advisory vote to approve our executive compensation or on any stockholder proposals.

In their discretion, the proxy holders named in the proxy are authorized to vote on any other matters that may properly come before the Annual Meeting and at any continuation, postponement or adjournment thereof. The Board knows of no other items of business that will be presented for consideration at the Annual Meeting other than those described in this proxy statement. In addition, other than the stockholder proposal described in this proxy statement, no other stockholder proposal or nomination was received on a timely basis or was subsequently withdrawn, so no such matters may be brought to a vote at the Annual Meeting.

Inspector of Election and Counting of Votes

All votes will be tabulated as required by Delaware law, the state of our incorporation, by the inspector of election appointed for the Annual Meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes. Shares held by persons attending the Annual Meeting but not voting, shares represented by proxies that reflect abstentions as to one or more proposals and broker non-votes will be counted as present for purposes of determining a quorum.

Election of Directors.We have a majority voting standard for the election of directors in an uncontested election, which is generally defined as an election in which the number of nominees does not exceed the number of directors to be elected at the meeting. In the election of directors, you may either vote “for,” “against” or “abstain” for each nominee. Cumulative voting is not permitted. Under our majority voting standard, in uncontested elections of directors, such as this election, each director must be elected by the affirmative vote of a majority of the votes cast by the shares present in person or represented by proxy. A “majority of the votes cast” means that the number of votes cast “for” a director nominee exceeds the number of votes cast “against” the nominee. For these purposes, abstentions will not count as a vote “for” or “against” a nominee’s election and thus will have no effect in determining whether a director nominee has received a majority of the votes cast. Brokers do not

have discretionary authority to vote on this proposal. Broker non-votes will have no effect on the election of directors as brokers are not entitled to vote for or against a nominee without instruction from the beneficial owner. If a director nominee is an incumbent director and does not receive a majority of the votes cast in an uncontested election, that director will continue to serve on the Board as a “holdover” director, but must tender his or her resignation to the Board promptly after certification of the election results of the stockholder vote. The Governance and Nominating Committee of the Board will then recommend to the Board whether to accept the resignation or whether other action should be taken. The Board will act on the tendered resignation, taking into account the recommendation of the Governance and Nominating Committee, and the Board’s decision will be publicly disclosed within 90 days after certification of the election results of the stockholder vote. A director who tenders his or her resignation after failing to receive a majority of the votes cast will not participate in the recommendation of the Governance and Nominating Committee or the decision of the Board with respect to his or her resignation.

Management Proposals (Ratification of Ernst & Young LLP and Advisory Vote on Executive Compensation) and Stockholder Proposal.The ratification of the selection of Ernst & Young LLP, the approval of the advisory vote on our executive compensation and the approval of the stockholder proposal, if properly presented at the Annual Meeting, each require the affirmative votes of the holders of a majority of the shares present or represented by proxy at the Annual Meeting and entitled to vote on the matter. Abstentions will have the same effect as votes “against” each proposal.

Because brokers have discretionary authority to vote on the ratification of the selection of Ernst & Young LLP, we do not expect any broker non-votes in connection with the ratification. Brokers do not have discretionary authority to vote on the advisory vote on our executive compensation or on the stockholder proposal. Broker non-votes, therefore, will have no effect on the advisory vote on our executive compensation or on the stockholder proposal as brokers are not entitled to vote on such proposals in the absence of voting instructions from the beneficial owner.

Solicitation of Proxies

We will bear the entire cost of solicitation of proxies, including preparation, assembly and mailing of this proxy

statement, the proxy, the Notice and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding shares of our Common Stock in their names that are beneficially owned by others to forward to those beneficial owners. We may reimburse persons representing beneficial owners for their costs of forwarding the solicitation materials to the beneficial owners. Original solicitation of proxies may be supplemented by telephone, facsimile, electronic mail or personal solicitation by our directors, officers or staff members. No additional compensation will be paid to our directors, officers or staff members for such services. In addition, we have retained D.F. King & Co. to assist in the solicitation of proxies for a fee of approximately $150,000 plus distribution costs and other costs and expenses. A list of stockholders entitled to vote at the Annual Meeting will be available for examination by any stockholder for any purpose germane to the Annual Meeting during ordinary business hours at our principal executive offices at One Amgen Center Drive, Thousand Oaks, California, 91320-1799 for the ten days prior to the Annual Meeting and also at the Annual Meeting.

the Annual Meeting to be admitted. The items that you must bring with you differ depending upon whether or not you were a record holder of our Common Stock as of the close of business on March 21, 2016. A “record holder” of stock is someone whose shares of stock are registered in his or her name in the records of the Company’s transfer agent. Many stockholders are not record holders because their shares of stock are registered in the name of their broker, bank, trust or other nominee, and the broker, bank, trust or other nominee is the record holder instead.All persons must bring a valid personal photo identification (such as a driver’s license or passport). If you are a record holder, at the Annual Meeting, we will check your name for verification purposes against our list of record holders as of the close of business on March 21, 2016.
