Disclaimer of Warranties. THE SERVICES AND ALL INFORMATION, PRODUCTS, AND OTHER CONTENT INCLUDED IN OR ACCESSIBLE FROM THE SERVICES ARE PROVIDED “AS IS” AND WITHOUT WARRANTIES OF ANY KIND (EXPRESS, IMPLIED, AND STATUTORY, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE), ALL OF WHICH BRITANNICA EXPRESSLY DISCLAIMS TO THE FULLEST EXTENT PERMITTED BY LAW.
Limitation of Liability. IN NO EVENT SHALL BRITANNICA, ITS DIRECTORS, OFFICERS, SHAREHOLDERS, PARENTS, SUBSIDIARIES, AFFILIATES, AGENTS AND LICENSORS, OR CONTENT PROVIDERS BE LIABLE: (i) FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATED TO THE USE, INABILITY TO USE, PERFORMANCE OR NONPERFORMANCE OF THE SERVICES, EVEN IF BRITANNICA WAS PREVIOUSLY ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND REGARDLESS OF WHETHER SUCH DAMAGES ARISE IN CONTRACT, TORT, UNDER STATUTE, IN EQUITY, AT LAW, OR OTHERWISE; AND (ii) FOR ANY DAMAGES, LOSSES AND/OR CAUSES OF ACTION EXCEEDING ONE THOUSAND U.S. DOLLARS (US $1,000) IN THE AGGREGATE.
SOME JURISDICTIONS DO NOT ALLOW LIMITATIONS ON IMPLIED WARRANTIES OR THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE LIMITATIONS AND EXCLUSIONS MAY NOT APPLY TO YOU.
This section applies to any dispute EXCEPT DISPUTES RELATING TO THE ENFORCEMENT OR VALIDITY OF BRITANNICA’S INTELLECTUAL PROPERTY RIGHTS. The term “dispute” means any dispute, action, or other controversy between you and Britannica or its directors, officers, shareholders, parents, subsidiaries, affiliates, agents, licensors or content providers concerning the Services or this Agreement, whether in contract, warranty, tort, statute, regulation, ordinance, or any other legal or equitable basis. “Dispute” will be given the broadest possible meaning allowable under law.
Binding arbitration. Any dispute will be conducted exclusively by binding arbitration governed by the U.S. Federal Arbitration Act. You are giving up the right to litigate (or participate in as a party or class member) all disputes in court before a judge or jury. Instead, all disputes will be resolved before a neutral arbitrator, whose decision will be final and binding. Any court with jurisdiction over the parties may enforce the arbitrator’s award.
Class action waiver. Any proceedings to resolve or litigate any dispute in any forum will be conducted solely on an individual basis. Neither you nor Britannica will seek to have any dispute heard as a class action, private attorney general action, or in any other proceeding in which either party acts or proposes to act in a representative capacity. No arbitration or proceeding will be combined with another without the prior written consent of all parties to all affected arbitrations or proceedings.
Claims or disputes must be filed within one year. To the extent permitted by law, any claim or dispute must be filed within one year. The one-year period begins when the arbitration notice first could be filed. If such a claim or dispute is not filed within one year, it shall be permanently barred.

Not Advice. Information contained in the Services is not intended to be medical, legal, tax, financial or other advice and should not be considered medical, legal, tax, financial or other advice, nor is it intended to replace consultation with a qualified physician, attorney or other professional.
Definitions. As used in these additional terms, “you” or “yours” refers to each person who establishes a subscriber account (“Account”) or who is authorized to access and use any of the Subscription Services.
Account. You are responsible for all use of your Account under any user ID (username or email address) or password by any person and for ensuring that all use of your Account complies fully with the provisions of this Usage Agreement.
Subscription Fees and Changes. Subscription charges begin on the date your Services subscription is activated or, if applicable, on the date your free trial period ends, and will be billed to your credit or charge card each month (for monthly subscriptions) or year (for annual subscriptions) thereafter. You acknowledge and agree that you will not receive a bill in the mail for your subscription. Britannica reserves the right to increase subscription rates at any time. Changes to standard subscription rates will be posted at http://corporate.britannica.com/standard_rates.html or in a Britannica communication to you. Increases in subscription rates will apply to existing accounts at the time of their renewal and will not exceed the standard subscription rate that has been in effect and posted for at least 30 days. Reductions in the standard subscription rate will not necessarily be reflected in your renewal subscription rate. Customers subscribing at specially discounted promotional rates may be subject to varying rate increases, none of which shall exceed the standard posted subscription rate.
Termination of Subscription and Free Trial. Either party shall have the right to terminate your subscription at any time by providing notice of termination to the other. In the event of termination of your subscription by either party, you shall have no claims against Britannica or its affiliates. Termination of your subscriptions or free trial automatically terminates your license to use the Subscription Services and any content or other material contained therein. If you acquired an annual subscription to one of the Subscription Services and you terminate your subscription within 30 days of the date of activation of your Account, you are eligible to receive a refund of the subscription fee paid to Britannica; you must contact Britannica Customer Support to receive this refund. If you are a resident of the Netherlands, you can terminate at any time during your annual subscription, on 30 days notice, and receive a pro-rated refund. If you acquired a monthly subscription to the Subscription Services or if your subscription is acquired with a Promotion Certificate and you terminate your subscription, you will not receive any refund of the subscription fee paid to Britannica. If your subscription to the Subscription Services was acquired with a Gift Certificate and you terminate your subscription within 30 days of the date your Gift Certificate was acquired from Britannica, you are eligible to receive either: (a) a refund of the subscription fee paid to Britannica (available only to the party acquiring your Gift Certificate from Britannica); (b) a credit towards the price of acquiring other Britannica products or services; or (c) a credit towards the future subscription fee for an existing Subscription Services subscription. You must contact Britannica Customer Support to receive these remedies. If Britannica terminates your subscription, other than as a result of your breach of this Agreement, Britannica will refund to you a pro rata portion of the subscription fee paid to Britannica, if any, for the unexpired portion of your subscription.
Subscription Changes. If you acquired an annual subscription to the Subscription Services and you wish to change to another Subscription Service offering you may do so without penalty within 30 days of the activation of your Account. You must contact Customer Service to request this or other changes from one Subscription Service to another. If you acquired a monthly subscription to the Subscription Services and you wish to change to another Subscription Service offering, contact Customer Service, the change will be made effective when your current monthly term ends.
Renewals and Cancellations. Your subscription will renew automatically unless we terminate it or you notify us by telephone or email (receipt of which must be confirmed by email reply from us) of your decision to cancel your subscription. You must cancel your subscription before it renews in order to avoid billing of subscription fees for the renewal term to your credit card. Instructions on how to cancel your subscription are available at http://account.britannica.com. In the event that you cancel your subscription, unless otherwise required by law, subscription fees will not be refunded, applied to another subscription, or transferred to anyone else and are not convertible to cash or other form of credit. Payments made as part of a monthly subscription cannot be used as credit toward annual subscription charges and are non-transferable.
Credit Cards or Charge Cards. You agree that you will provide a major credit or charge card (e.g., MasterCard, Visa, American Express, or Discover) that Britannica may charge for all subscription fees or other amounts payable to Britannica. With respect to such charges, you give the following authorization:
I authorize automatic credit or charge card billing by Britannica. I agree that the charges described above will be billed by Britannica to the credit or charge card that I have provided to Britannica in my Account information, or otherwise when I applied for the Subscription Services. I understand that all fees and charges are nonrefundable. I agree that Britannica will not be responsible for any expenses that I may incur resulting from overdrawing my bank account or exceeding my credit limit as a result of an automatic charge made under this Agreement.
Account Information. You agree to provide current, complete, and accurate information for your Account in order to receive access to the Subscription Services. You agree to promptly update all Account information to keep your account current, complete, and accurate (such as a change in billing address, credit or charge card number, or credit or charge card expiration date) and you must promptly notify Britannica if your credit or charge card is cancelled (for example, for loss or theft) or if you become aware of a potential breach of security, such as the unauthorized disclosure or use of your log-in and password. Changes to such information can be made by going to the Account Maintenance area at http://account.britannica.com. If you fail to provide Britannica any of the foregoing information, you agree that Britannica may assume that your credit or charge card is either still valid or that it has been renewed and may continue charging you for the Subscription Services to which you have subscribed, unless you have cancelled your subscription.
