Ad contract terms and conditions Liability Advertisers and advertising agencies assume all liability for advertisements printed (including text, representation and content) and also assume responsibility for any claims arising therefrom made against the Publisher. Publisher assumes no liability for errors in key numbers. Right to refuse Publisher reserves the right to refuse any advertising which is not in keeping with the publication's standards. "Advertorials" Advertisements that simulate the publication's format are not accepted and the Publisher reserves the right to place the word "Advertisement" with the copy that represents editorial material. Publisher reserves the right to repeat previous copy if no changes are received by closing date for any insertions ordered. Rate changes Rate changes will be announced at least 90 days prior to publication of the first issue affected by new rates. Contract may be cancelled at the time a rate change becomes effective without incurring a short rate, provided the contract has been fulfilled up to the time of cancellation. Billing Advertisers will be short-rate billed within the contract year (or the calendar year, should no contract have been drawn up), if they do not use the amount of space upon which their billings have been based. Advertisers will be rebated within the contract year (or the calendar year, should no contract have been drawn up), if they have earned a higher frequency. Recognized advertising agencies are allowed 15% of gross billing, provided account is paid in full within 30 days of date of invoice. No agency commission or discount applies to classified rates of mechanical charges. If Agency defaults on payment, Publisher will hold Advertiser responsible for payment. Publisher shall bill Agency monthly and such bills shall be due and payable by Agency 30 days from the date thereof.
