4. 1. Introduction
In 2009, during the time of recession and financial sector was feeling the heat, a big consolidation took
place in the sector. One of the leading investment banks Citibank sold 51% share of its Global wealth
Management division, called Smith Barney, to Morgan Stanley. The remaining 49% would be with Citi
group and the joint venture would be known as Morgan Stanley Smith Barney (MSSB). As of now, Citi
has its own MIS and reporting system for variable loan products which Morgan Stanley does not have.
Since business processes are not the same in two groups, there is a need to develop a new system to
perform variable interest rate lending products reporting. The new system will be known as “Interest rate
Management System” or IRMS.
This document tries to define the overall software requirements for „Interest Rate Management System‟.
It aims to define the requirements exhaustively and accurately. The final product will be having only
features/functionalities mentioned in this document and assumptions for any additional
functionality/feature should not be made by any of the parties involved in
developing/testing/implementing/using this product. In this case it is required to have some additional
features, a formal change request will need to be raised and subsequently a new release of this document
and/or product will be produced as per the agreement.
1.1 Purpose
This specification document describes the capabilities that will be provided by the software application
„Interest Rate Management System‟. It also clearly mentions the various required constraints by which
the system will abide. The intended audiences for this document are the development team, testing team
and end-users (financial advisor in this case) of this product.
1.2 Scope
The software product „Interest Rate Management System‟ will be an MIS and reporting application. The
application will be used for managing the activities of library of Morgan Stanley Smith Barney. The
application will manage the information of various clients and investors that have relationships with the
investment bank, their wealth and assets, various lending product information, past association/track
record, assigned investment banker/financial advisor‟s details and the net revenue generated. Printable
reports regarding list of clients, investment bankers, historical data and other relevant details will be
generated. The system will serve as MIS and reporting tool where rates are variable in nature.

6. 2. Overall Description
2.1 Product Perspective
The software product will be a web based system which would run on an intranet. It will also be
connected to the outside world through a secured channel to gather real time data on interest rates.
Internally, it would interact with several other systems to receive and disseminate data.
2.1.1 System Interface
The Interest Rate Management System would need to interact with a variety of systems to facilitate the
function. It will talk to following systems:
The new system will interact, through the internet, to the external world. The base interest rates
(LIBOR rates) are determined on a daily basis and released by Reuters. Hence the IRMS will
fetch these daily feeds for its reporting purpose.
The new system will take inputs from another system for client details and stores the same. Since
IRMS is only a reporting tool, it does not have visibility to the new clients or changes in existing
data. Such details will be taken from other internal systems every day.
The job of IRMS is to serve as an MIS tool only. It does not process the loans or other
6|Page

7. computations. For this purpose it submits data to other sub-systems. Any loans will be saved in
IRMS first before any further processing.
2.1.2 User Interface
The Interest Rate Management System will have a user friendly and menu based interface. Following
screens will be provided:
A Login screen for entering the username, password and role (Administrator, Financial Advisor,
Management) will be provided. Access to different screens will be based upon the role of the
user.
There will be a screen which will list all borrower‟s data falling into a particular region,
associated with a particular FA or from the same branch. The screen would give details like
Loan No., Borrower Name, Address, Branch, FA, Loan Amount, Interest Rate, Interest Amount,
Loan Issue Date, Next Installment Due Date and Loan status (active, pending, approved,
rejected, cancelled or expired).
The above list will have the Borrower name as a hyperlink. By clicking on the same, a new
screen will appear with will list out the past record for the same recipient. The screen will have
details like Loan No., Borrower Name, Address, Branch, FA, Loan Amount, Interest Rate, Issue
Date and Loan Status.
There will be a standalone screen which would display all lending products offered by MSSB.
The screen will have details like Loan Product, Base rate, Spread (Premium) and Total Charged
Rate. This base rate gets updated daily, based on Reuters input.
There will be a search screen which will have the Loan No., Name, Branch, FA, Issue Date, Due
Date, Loan Product, Loan status and fields. The fields will alone or with combination of other
fields will be used to search a particular account or a set of accounts.
There will be a screen which will facilitate the addition of new records. This screen is supposed
to be used on the ad - face basis (actual updating will happen through a daily batch process).
Only administrators will be able to perform this function.
A separate screen would provide functionality to modify or delete an existing record. As
mentioned above, only administrators will have authority to perform this function.
One screen would be accessible to administrators only and contain audit information (changes
done in the database).
The following reports (only on demand basis) will be generated by this system:
A report containing a list of all borrowers falling into a particular region, associated with a
particular FA or from the same branch will be created. Reports can also be generated on other
fields such as Loan issued on a specific date, for a definite installment date, accounts pertaining
to same lending products and so on.
A report containing historical records of any particular beneficiary for limited or all time period,
7|Page

8. will be generated.
A report containing a list of accounts in a desired time period along with their loan amounts will
be created.
A list showing the trend of rates (as determined by Reuters) for any one or all products for the
past six months will be published.
A report showing new added loan accounts in a given time period will be published.
