Calculation ( The results should be rounded off to two decimals. 20% )36.（1）CIF= ( FOB+F) / (1 - premium rate×110％）＝(1000+200)/(1-1%×110％)=1200/(1-0.011)＝1200/0.989≈1213.35 USD per metric tonI.e. this exporting Company should offer CIF Yokohama USD1213.35 per Metric Ton to its customer with the same profit.( 2 )CIFC5%＝CIF/（1－5％）＝1213.35/0.95≈1277.21 USD per metric tonSo, the exporting Company should offer CIFC5% Yokohama USD 1277.21 per metric ton to its customer with the same profit.( 3 )The domestic purchasing price plus domestic total charges minus the export tax rebate is domestic cost of export.I.e. the total domestic cost = 6000×100 + 13000 －3000= 610000 RMBThe revenue in RMB = foreign exchange earning × exchange rate= FOB ×100×exchange rate=1000×100× exchange rate=100000 × 6.8= 680000 RMBSo, the rate of profit = (revenue－domestic cost) ÷ domestic cost × 100%= (680000－610000) ÷ 610000 × 100%≈11.48%Ⅳ. Case Study ( 10% )37. ( 1 )According to CISG, the two companies have not conculded a contract.( 2 ) CISG Article 19, “1）A reply to an offer which purports to be an acceptance but contains additions, limitations or other modificationsis a rejection of the offer and constitutes a counter-offer.2）However, a reply to an offer which purports to be an acceptance but contains additional or different terms which do notmaterially alter the terms of the offer constitutes an acceptance,unless the offeror, without undue delay, objects orally to thediscrepancy or dispatches a notice to that effect. If he does not soobject, the terms of the contract are the terms of the offer with themodifications contained in the acceptance.3) Additional or different terms relating, among other things, tothe price, payment, quality and quantity of the goods, place and timeof delivery, extent of one party's liability to the other or the settlementof disputes are considered to alter the terms of the offer materially. ”( 3 ) On 17th May, 2010, the french company replied by FAX, “ we accept your offer dated 15th May, 2010, but at the price of FOB ShanghaiUSD 80 per set, shipment during October, 2010.”That is to say, the french company altered the price and the time of shipment in the chinese company’s offer dated 15th May, 2010.So the reply made by the french company dated 17th May 2010 wasa counter-offer and a new offer.Then, the offer made by the chinese company dated 15th May 2010 became invalid.The chinese company hasn’t accepted the new offer made by the french company dated 17th May 2010.The reply made by the french company dated 19th May 2010 was a new offer too. And the chinese company hasn’t accepted thenew offer made by the french company dated 19th May 2010 too.So the two companies have not conculded a contract.V.
