Final Examination: 
Orale

According to University regulations and up to different indications, in the academic year 2020/21 the exam will be carried out remotely. The remote exam will be carried out on a specific University platform (e-learning). A student can decide to carry out the exam in two different methods.
METHOD 1 – Total exam:
At the end of the course, during the exam sessions, tests that cover the entire program of the course will be organized. During the total exam (at a distance), the use of calculators, manuals and notes will be allowed.
The test will be divided into two parts and will be designed to evaluate the calculation skills, the knowledge of terminology, the main statements presented during the course and the analytical skills developed by the student.
Part 1: The first part of the exam will be composed by Quiz (multiple choice) delivered through the e-learning platform. The student will have to answer 6 multiple choice or numerical answer questions in 20 minutes. By correctly answering at least 4 questions, students will be admitted to the second part of the exam. Otherwise the exam will be terminated, and the test will be evaluated as insufficient. There is no penalty for incorrect answers. Each correct answer is worth 2 points.
Part 2: The second part will consist of two exercises, composed by several questions. Each exercise is worth up to a maximum of 10 points.
The student will have 40 minutes to solve the exercises on a sheet of paper with black pen and upload a legible image of the paper to the e-learning platform. Further details on how to create and upload the solutions of the exercises will be made available on the e-learning page of the course.
The exam is passed if the sum of the scores obtained in the two parts is not less than 18 (eighteen), with a minimum of 8 (eight) points in the first part. Scores higher than 30 will be registered as 30 with honors.

MODE 2 - Partial exams:
At the end of the first cycle of lessons, in the week of teaching interruption, and at the end of the course in December, two partial exams will be organized mainly concerning the topics of the part of the course just ended.
The first partial exam will last 40 minutes, will be worth 16 points and consists of 12 short questions in the form of quiz (multiple choice question) concerning calculation skills and knowledge of the main definitions and theoretical concepts addressed in class. Students will be admitted to the second partial exam if the score obtained in the quizzes is greater than or equal to 6.
The second partial exam is divided into two parts. The first part of the exam, worth 6 points, is composed of short questions in the form of quiz (multiple choice question). The student must achieve at least 4 points to be able to access the second. The second part of the exam, evaluated 10 points, is composed of more complex exercises, in which the student is required to use the calculation skills and theoretical results presented in the course in an appropriate way to provide the solution to the proposed questions. There is no minimum score for this part.
The second partial exam is also passed with at least 6 points.
The exam is passed if both partial tests are passed and the sum of the points obtained is no less than 18 (eighteen). Honors are awarded to a sum greater than 30.
Students with DSA: Students with DSA are required to contact the disabled service (servizio.disabili@uninsubria.it) to define the individualized Training Project that must be sent to the course holder within 10 days before the exam session that the student intends to sustain.

Assessment: 
Voto Finale

At the end of the course students should be able to:
a) Construct common financial contracts, such as leasing contracts, consumer credit and loans;
b) Compute some legal indicators linked to financial contracts, such as TAN, APR, ISC;
c) Evaluate the convenience of some financial transactions according to the most accredited criteria that allow the maximization of profit in a given time horizon;
d) Critically comment on criteria inconsistent with the goal of maximizing profit as set time horizon;
e) Compute prices and yields of main fixed income securities, as well as the Duration and the underlying term structure;

Convenzionale

The course includes 30 hours of lectures in which the theoretical topics and the methods of solution of the exercises will be discussed. During the lessons exercises can be assigned both for individual study and to solve in the classroom.
An additional 30 hours will be fulfilled through an individual guided study through the University e-learning platform.
Exercises in preparation for the exams will be provided.

Starting from the summer session of the academic year 2019/2020 the examination procedures and the program will be those described. Students who have attended the course in previous years will have to take the exam with the new methods.
