36
Q

For most of the operations that involve an annuity, the payments are due at the end of each period.

A

True

37
Q

Annuities paid at the end of each period are called

A

an ordinary annuity/immediate annuity/ post-payable annuity.

38
Q

Some examples of ordinary annuities are

A
  1. Wages paid to the workers
  2. Mortgage payments
  3. Coupons of a bond
39
Q

an ordinary annuity is also called

A

an immediate annuity or a post-payable annuity.

40
Q

An annuity due/ pre-payable annuity is one where

A

the payments are due at the beginning of each period.

41
Q

Some examples of annuities due are

A

house rents or leasing payments

42
Q

We can verify that an annuity due is the same as an immediate annuity anticipated in one period.

A

True

43
Q

The relation between an annuity due and an immediate annuity is

DV Annuity due = DV immediate annuity*(1+i)

A

True

44
Q

When all the payments of the annuity are equal, we are dealing with a __________

A

constant annuity

45
Q

The initial value of a constant annuity would be the result of discounting all the capitals to t=0.

A

True

46
Q

The discounted value (DV) of a constant annuity is equal to the sum of the elements of a geometric progression.

A

True

C*∑ 1/(1+i)^t, where t begins at 1

47
Q

To calculate the discounted value in excel, the formula is

A

DV = C*PV, where PV = an)i = (1-(1+i)^-n)/i

48
Q

PV = an)i = (1-(1+i)^-n)/i

A

True

49
Q

In Excel, PV = (rate;nper;-C) or C*PV(rate;nper;-1)

A

FALSE

DV = (rate;nper;-C) or C*PV(rate;nper;-1)

50
Q

The compounded value (CV) of a temporary constant annuity would be the result of accumulating
the discounted value until the end.

A

True

51
Q

In a temporary constant annuity, CV =

A

CV = DV(1+i)^n

52
Q

Perpetual constant annuities are …

A

when the term of the annuity is constant and not known

when we assume that the payments of the annuity will continue forever

When the term of the annuity is infinity (t=∞).

53
Q

Perpetual constant annuities are when the term of the annuity is constant and not known

A

True

54
Q

The discounted value of a perpetual annuity is DV = a∞)i or DV = C/i

A

True

DV = a∞)i

55
Q

The value of 𝑎n)i for infinitive terms is 1/i

A

True

56
Q

There is no “end of annuity”, it does not make sense to talk about the compounded value/ final value of perpetual annuities.

A

True

57
Q

When the annuities are different for each period, we are dealing with a __________

A

varying annuity.

58
Q

If the capitals of a varying annuity do not have any known relationship between them, we can not apply any rule that provides us with the calculation of the value of the annuity.

A

True

59
Q

In a varying annuity, because no rule can be applied for capitals without a known relationship, the capital value will have to be calculated by taking all the capitals of the annuity up to the time of the valuation and adding them at that moment.

A

True

60
Q

If the capitals of a varying annuity have some kind of mathematical relationship between them, it may be possible to find abbreviated calculation formulas.

A

True

61
Q

Two types of relationships between capitals of varying annuities are:

A
  1. Those that evolve following an arithmetic progression

2. Those that evolve following a geometric progression.

62
Q

In annuities with payments varying in arithmetic progression, the difference between two consecutive payments is a constant (d).

A

True

d = Ct+1 - Ct

63
Q

We can compute the value of any payment of an annuity with payments varying in arithmetic progression if we know the value of any other payment and the value of the difference.

A

True because the difference b/w annuities with arithmetic progression is constant.

Ct = C1 + (t-1)*d

64
Q

The discounted value of an annuity whose payments vary in arithmetic progression is equal to (without demonstration): DV = (C1 * n * d + d/i)PV - (nd)/i

A

True

Where 𝐶1 is the first payment of the annuity;
𝑛 is the term of the annuity;
d is the difference between two consecutive payments;
i is the rate of interest, compounding on the payment interval

65
Q

In the case of a perpetuity whose payments vary in arithmetic progression (without demonstration), the discounted value would be: DV = (C1 + d/i) * i/1

A

True

66
Q

In annuities with payments that vary in geometric progression, whose payments grow (or decrease) in a constant growth (decreasing) rate g, the ratio between any given payment and the preceding payment will be equal to 1+g.

A

True

67
Q

In annuities with payments that vary in geometric progression, whose payments grow (or decrease) in a constant growth (decreasing) rate g, Ct+1 = Ct(1+g)

A

True

68
Q

In annuities with payments that vary in geometric progression, whose payments grow (or decrease) in a constant growth (decreasing) rate g, we can calculate the value of any payment if we know the value of the first payment and the value of g.

A

True

Ct = C1*(1+g)^(n-1)

69
Q

A fractional variable annuity would be an annuity …

A
  1. in which its terms are kept constant for a certain number of K periods
  2. after that number of periods, the capital, K + 1, would be obtained by applying a law of progression (arithmetic or geometric) with respect to the previous capital
  3. and that capital, K + 1, would remain constant during other K periods
  4. this pattern would be maintained until the end of the rent.
70
Q

An annuity which the terms are kept constant for a certain number of K periods, after which, the
capital, K + 1, would be obtained by applying a law of progression (arithmetic or geometric) with respect to the previous capital, and that capital, K + 1, would remain constant during other K periods (with this pattern would be maintained until the end of the rent) is called _________________.

A

Fractional varying annuity

71
Q

Typical examples of fractional varying annuities are …

A
  1. salaries: normally, the monthly salary is
    constant during the year; Once it is finished, a revision of it (usually geometric) is produced, which is kept constant again for one year until the next revision.
  2. rents
72
Q

Normally, this is constant during the year, and once the year is finished, a revision of it (usually geometric) is produced, which is kept constant again for another year until the next revision.
