BKF.com provids banks accss to sophisticated financial information and analysis via th web, enabling them to instantly evaluat both personal and commercial loan applications. To btter focus on its client services, BKF.com is considering outsourcing som of its internal functions. Its controller, Jenny Le, suggests starting with the company's intrnal email system. She recntly attended a conference and learned that GTE and NBC outsourc their email function to companis such as Google and Yahoo. Lee bgan her analysis by identifying the total costs rlated to last month's in-house email opration when there were 3,595 employee mailboxes:

Variable Costs (varies with mailboxes)
Email licens	$20,132
Virus protection licens	3,595
Miscellaneous	12,942
Fixed Costs
Computer hardwar	30,198
Total costs	$66,867

Le analyzed the computer hardware costs, identifying its thre components:

1. $13,891 were allocatd costs that will continue even if the email system is abandoned.
2. $4,530 were non-personnel direct costs that will b avoided if the email system is abandoned.
3. $11,777 were the monthly salaries for two, qually paid interns who worked only on the email system.

Mail.com, a lading provider of internet messaging outsourcing services, has offerd to host BKF.com's email function for $11.40 per mailbox. BKF.com will still need to pay th virus protection license fee and on of the interns to maintain the virus protection software.

A company has agred to pay BKF.com $3,000 a month to use the computer storage space that will becom available if BKF.com outsources its email function.

Finally, Lee stimates that 4,085 mailboxes will be required per month next year.

Q: By how much will BKF.com's monthly profits chang if they decide to outsource its email function to Mail.com instead of managing the servic internally?
