The summary analyzes patient data from NCLEX Memorial Hospital's Infectious Diseases Unit. Over 65 patients ranging from 41-84 years old were admitted with an infectious disease. A PowerPoint presentation was created to examine the mean, median, mode, range, standard deviation, variance, 95% confidence interval, and conduct a hypothesis test on the average patient age. The analysis aimed to determine if patient age plays a critical role in treatment method. The presentation concluded that the average patient age was 63 years old and the hypothesis test found no evidence that the average age was less than 64 years old.

CORPORATE FINANCE
Corporate finance is an area of finance that deals with sources
of funding, the capital structure of corporations, the actions that
managers take to increase the value of the firm to the
shareholders, and the tools and analysis used to
allocate financial resources.
What is Corporate Finance?
Three main questions need to be answered.
1. What long-term investments should you make? That is, what
lines of business will you be in, and what sorts of building,
machinery and equipment will you need?
2.Where will you get the long-term financing to pay for your
investment? Will you bring in other owners, or will you borrow
the money?
3.How will you manage your everyday financial activities, such
as collecting from customers and paying suppliers?
The Financial Manager
The financial management function is usually associated with a
top officer of the firm, such as a finance director (FD) or chief
financial officer (CFO).
Coordinates the activities of the treasurer and the controller.
Controller: handles cost and financial accounting, tax payments,
and management information systems.
Treasurer: responsible for managing the firm’s cash and credit,
its financial planning and its capital expenditures.

6. Finance function: is related to the three general questions above
Accounting function: takes all the financial information and
data that arises as a result of ongoing business activities, and
presents this in ways that allow management to assess the
performance and risk of their firms (financial accounting) and
make informed decisions on further corporate activity
(management accounting).
Financial Management Decisions
Capital budgeting: the process of planning and managing a
firm’s long term investments (so related to question 1). The
financial manager tries to identify investment opportunities that
are worth more to the firm that they cost to acquire (value of the
cash flow generated by an asset exceeds the cost of the asset).
They types of investment opportunity that would typically be
considered depend in part on the nature of the firm’s business.
Financial management must always not only be concerned with
how much cash they expect to receive, but also with when they
expect to receive it, and how likely they are to receive it.Size,
timing, risk of future cash flows evaluation is the essence of
capital budgeting.
Capital Structure:the mixture of long-term debt and equity
maintained by a firm (second question: ways in which the firm
obtains and manages the long-term financing it need to support
its long-term investments).
Equity: the amount of money raised by the firm that comes from
the owners’ investment.
Long-term debt:
long-term borrowing by the firm (longer than one year) to
finance its long-term investments.
Two concerns in this area: 1. How much should the firm

7. borrow, so which mixture of debt and equity is best? This
choice will affect both risk and the value of the firm. 2.What
are the least expensive sources of funds for the firm?
-Pie and shareholders and creditors from percentage of the cash
flow.
-Firms have great flexibility in choosing a financial structure.
Working Capital Management
Working Capital: A firm’s short term assets and
liabilities.Concerned with the third question. Managing working
capital is a day-to-day activity which ensures that the firm has
sufficient resources to continue its operations and avoid costly
interruptions. This involves a number of activities related to the
firm’s receipt and disbursement of cash.
The goal of financial management
The financial manager in a corporation makes decisions for the
shareholders of the firm. We thus need to answer a more
fundamental question than listing possible goals: from the
shareholder’s point of view, what is a good financial
management decision?
-Good decisions increase the value of the equity and vice versa
-So, acting in the shareholder’s best interest. Goal:
Shareholders are the last ones in getting money, so when they
are winning, everybody is winning. maximize the current value
per share of the existing equity.
-Avoids the problems stated earlier because there is no
ambiguity or difference between long-term and short-term
issues.
-Corporate finance: the study of the relationship between
business decisions and the value of the equity in the business.
Primary versus secondary markets
Primary market: The original sale of securities by governments

8. and corporations.
Secondary markets: Those markets in which these securities are
bought and sold after the original sale.
-Equities are issued solely by corporations. Debt securities are
issued by both government and corporations.
Corporation
Is a business created as a distinct legal entity composed of one
or more individuals or entities. It is in size the most important
form of business organization.
-It is a legal person, and so distinct from its owners, and has its
own rights, duties and privileges.
-A corporation can even be a general or limited partner in a
partnership, and can own equity in another corporation.
-Starting a corporation is more complicated than starting the
previous two. It involves preparing articles of incorporation (or
a charter), and amemorandum of association
The articles of incorporation must cotain a number of things,
including the corporation’s name, its intended life (which can
be forever), its business purpose, and the number of shares that
can be issued. This normally has to be supplied to the country
of origin. For most legal purposes the corporation is a ‘resident’
of that country.
The memorandum consists of rules describing how the
corporation regulates its existence, e.g. the election of directors.
The memorandum may be amended or extended from time to
time by the shareholders.
Several advantages due to the separation of ownership and
management:
1.Ownership (represented by shares of equity can be readily

9. transferred
2.Life of the corporation is not limited
3.The company borrows money in its own name so, limited
liability (own investment).
4.The three points above make this form the best form for
raising cash.
Disadvantages:
1.It must pay taxes because it is a legal person, and money paid
to shareholders in the form of dividend is taxed again as income
to the shareholders. This is double taxation. Thus, taxation at
the corporate and personal level.
-Corporations are also called joint stock companies, public
limited companies or limited liability company.
Control of the firm: Control of the firm ultimately rests with
shareholders. They elect the board of directors, who in turn hire
and fire managers.
Shareholder rights: The conceptual structure of the corporation
assumes that shareholders elect directors, who in turn hire
managers to carry out their directives. Shareholders therefore
control the corporation through the right to elect the directors.
Introduction to valuation: the time value of Money
Time value of Money refers in the most general sense to the fact
that the euro today is worth more than an euro promised at some
time in the future. E.g. because of missed interest (‘growing
money’). It thus depends on the rate you can earn by investing.
Future value (FV): The amount of money an investment will
grow to over some period of time at some given interest rate.
Future value and compounding
Investing for a single period
If you invest for one period at an interest rate of r, your

10. investment will grow to (x+(x*r)).
Investing in more than one period
Compounding is the process of accumulating interest on an
investment over time to earn more interest.
Interest on interest: interest earned on the reinvestment of
previous interest payments.
Compound interest: interest earned on both the initial principal
and the interest reinvested from prior periods.
Simple interest: Interest earned only on the original principal
amount invested. The four terms above show that by investing
in more periods, the amount of money after interest consists of
four compounds
Bond valuation:When a corporation or government wishes to
borrow money from the public on a long term basis, it usually
does so by issuing or selling debt securities that are generically
calledBonds.
Interest rate risk:The risk that arises for bond owner from
fluctuating interest rates is called interest rate risk
The indenture : The indenture is the written agreement between
the corporation and the lender detailing the terms of the debt
issue. It is sometimes referred to as deed of trust
