Introduction: Some background information
Financial Mathematics (FMT), often variously
named as financial engineering, mathematical
finance, computational finance, analytical finance,
or quantitative finance, is one of the fascinating
areas of business management studies.
It is a multidisciplinary field that draws tools not

other disciplines, such as statistics, computer
science, finance, and economic theory, to deliver
sustainable solutions in the financial services
industry.

Mathematics with focus on fixed-income instruments in the world of academia,
industry and government.
An Overview of the Course
This course focuses on real-world cases in finance, business, and economics, where
attempts are made to apply mathematical concepts of interest theory as an important
field of management studies. You will be introduced to key concepts that are applied in
calculating present and accumulated values for various streams of cash flows as a
basis for use in sound asset/liability management and capital budgeting in modern
financial systems.
We will also revisit in application terms some of the commonly used financial market

Linkage with mission statement objectives
Business leadership:
This course gives an overall perspective of applied
mathematical / statistical finance and deals with the
key dimensions of financial and investment analysis
needed for informed decision-making in a
competitive environment.
Efficient and effective financial management across
the whole spectrum of financial markets, money,
capital, and derivatives, can help modern
organisations to move into a leadership position in
their chosen businesses.
Organizational excellence:
While dealing with financial capital interest and
capital budgeting dynamics, course discusses how
organizations and investors can be guided to
ensure value-added decision making in project /
investment portfolio choices.
Continuously stressing on fundamental investment
parameters, namely, cash flows, risk, return, time
value, in turns leads to organizational excellence in
an environment of rapid changes and uncertainty.
Value creation: Course deals with increasing the utility to all the
stakeholders through continuous optimal wealth-
generation by learning and applying various
quantitative tools and techniques that have
significant impact in the emerging financial
services industry.
Higher utility level automatically leads to higher-
value creation for all the stakeholders in the
system.
Dealing with change: Course applies mathematics of change for
making informed investment decisions and thus
exposes and equips students with tools,
techniques and frameworks on how to effectively
and efficiently measure risk and return in a
dynamic financial system. By so doing we can
gain further insights into how we can help our
organisations to operate sustainably, adapting as
necessary, and remaining relevant in todays
fast-pace and increasingly unpredictable
business environment.

First Steps Financial Mathematics (FMT) is a field of management studies that
deals with mathematic methods that are mostly used in financial
markets, which greatly help to improve the quality of decision-
making in a random and uncertain environment.
FMT is also a professional activity focused on the formulation and
study of mathematical models to solve practical business
problems, especially in the financial services industry
FMT thus basically deals with modelling of financial markets and
instruments / products.

FINANCIAL ANALYSIS FINANCIAL ECONOMICS FINANCIAL MATHEMATICS
FAs assess the viability, stability and profitability of a business or project, usually based on information taken from financial statements.
FEs study the structural reasons why a company may have a certain share price.
FMTs are basically modellers they take the share price as a given and attempt to use stochastic calculus to obtain the corresponding value of derivatives of the stock market movements.
Quantitative finance applications:
- Market movements - Portfolio returns/risk - Optimization - Corporate / capital
structuring, etc.

Interest (rate of return on capital) measures the yield
on capital typically over the course of a year expressed as
a percentage of the value of capital invested.
Often denoted, r, interest remains a central concept in
many economic theories.

Financial Markets
Financial market is a market in which people and
entities can trade financial securities, commodities, and
other fungible items of value at low transaction costs and
at prices that reflect supply and demand.
Securities = stocks and bonds
Commodities = precious metals and agricultural goods
Fungible items = goods of such nature or kind as to be
freely exchangeable or replaceable wholly or partly.

Some key issues in Financial Mathematics
Understanding how prices are set in financial markets.
Determining prices, manage risk, and identify profitable opportunities.
Finding fair prices for options and numerous other derivative securities used by investors as risk-hedging devices.
Evaluating portfolio performance.
Valuation determining expensive and cheap stocks.
Portfolio risk modelling and validation.
Higher-speed solutions algorithmic trading / statistical arbitrage to achieve ultra low latency.

A word about Financial Modelling
Financial modelling involves building an abstract representation (a model) of a real world financial situation.
A financial model is anything (from simple formulae to complex software package) that is used to compute, forecast or estimate financial numbers, or to represent a financial asset / portfolio / project / or any other investment
Key contribution to management:
Basically, to assist decision-making, planning and control processes.
Limitations: Watch for unrealistic / unfounded
assumptions.
Models may not fully explain or predict behaviour of people.
Models complexity may yield error.
Experience, skills, judgment / common sense are often needed to complement mathematical sophistications.

money at various points of time.
Valuation of obligations to pay various sums
of money at various points of time.

Exercises / problems/ cases 5. The management of K. Equipment Leasing Company Ltd is getting concerned about cost of funding its operations. Currently, the company books an average of 200 financial leases to its customers across various sectors and geographies globally. Its standard lease is for $1500000 for a 5-year tenor at in-built interest rate of 22% per annum. As a cost-saving measure, the CFO advised in a recent management retreat that the companys annuity policy should be changed from regular mode to annuity due. His advice was based on her estimates of the financial implications if rentals continue to be paid at the end of each period compared to when mad payable at the beginning. Some of the business development managers in the company believe that, given the strategic relationship the company currently has with 25% of the lessees, the contemplated change cannot be implemented without resistance by its long-established customers. The board of the company is meeting soon to take a final stand on this, and the Chairman wants your advice.

cases 5. The management of K. Equipment Leasing Company Ltd is getting concerned about cost of funding its operations. Currently, the company books an average of 200
financial leases to its customers across various sectors and geographies globally. Its
standard lease is for $1500000 for a 5-year tenor at in-built interest rate of 22% per
annum. As a cost-saving measure, the CFO advised in a recent management retreat
that the companys annuity policy should be changed from regular mode to annuity
due. His advice was based on her estimates of the financial implications if rentals
continue to be paid at the end of each period compared to when mad payable at the
beginning. Some of the business development managers in the company believe
that, given the strategic relationship the company currently has with 25% of the
lessees, the contemplated change cannot be implemented without resistance by its
long-established customers. The board of the company is meeting soon to take a
final stand on this, and the Chairman wants your advice.
Required:
How much more revenue realistically do you think the company can make by
changing its annuity policy on leases?
