Input:  Person1:     Did you see the information on sales for last year ? The sales review was made at our last board meeting . There's a great news for our shareholders . 
 Person2:  Yeah , I went over the figures this morning . We're finally started making money again ! 
 Person1:      We've never sold this much before , our growth this year has been phenomenal . We have captured 8 % of the market , up from last year by 120 % . Our strategy is working ! 
 Person2:  not only our annual sales brake a record , but our month by month earnings exceeded our forecast as well . After a two-year slump , we finally back in the black . 
 Person1:      The company's performance has improved since Wallace became president . He's made our little business into a real lucrative operation . Products are selling like hotcakes . 
 Person2:  I think our success is partly because of Wallace's contribution , and partly because of our new marketing strategy . Because of the new advertising campaign , we have become the top sellers in the field . 
 Person1:      Let's hope this stroke of good luck lasts . I hope we are over our financial difficulties for good . 
 Person2:  Let's hope it is !
