AI AI Oh, F#@%!

By Brent Pritchard

Twenty-two years is a long time to do anything. That was my tenure in Corporate America, where as a friend says I was able to “find a niche and crawl into it.”

As a commercial real estate finance professional, I remember when Amazon started the big move to develop its last mile delivery infrastructure. Let’s just say that more than one request for financing for a fulfillment center they would occupy crossed by desk.

As a lending platform, we could like Amazon’s credit at the same time as seeking out deals with Amazon-proof tenants. Think retail centers occupied with service companies in the business of nails and the like or with outparcels where people served up McDonald’s.

Here’s an excerpt from my book Would Your Boomerang Return? What Birds, Hurdlers, and Boomerangs Can Teach Us About the Time Value of Money (2023):

Rounding out this new take on the Time Value of Money is a simple and definitive 3-Step Systematic Approach for applying the Mathematics of Finance, which has benefits as it relates to analyzing and evaluating real-world Time Value of Money situations from the classroom to the boardroom and in between.

Brent, you’re saying that finance professionals can also benefit from this content?! That’s right! Before I traded in my office in Corporate America for a classroom, I remember one day when the cat had the tongue of not only a very seasoned finance professional but also everyone else in the room. None could find the words to describe Net Present Value!

I’m not the first, nor will I be the last, to draw a comparison to the world that is arguably better post-internet and what the future of business with AI might hold. I, for one, think the result will be net positive.

What will the “finance professional” who can’t analyze or interpret NPV do for a job? (At some time in the future, somewhere there will be an old MacDonald who has a farm…and on that farm they will have a cat, AI AI Oh….)

The Time Value of Money Trifecta.

By Brent Pritchard

Simplicity. Consistency. Connectivity. Before these words were inked, they were the unspoken rules of engagement for the mental project that later became a physical book.

I’ve written about the TVM Rules before. If you were thinking about writing them off, take a look at them with a fresh set of eyes. If you’re new to this blog or haven’t read my book Would Your Boomerang Return?, maybe this is the first time you’ve heard about these original TVM Rules.

Here’s an excerpt from my book Would Your Boomerang Return? What Birds, Hurdlers, and Boomerangs Can Teach Us About the Time Value of Money (2023):

Doing any of these is a Time Value of Money no-no:

1. Add or subtract or compare money in different points in time.

2. Fail to correspond the time span in between periods or payments (on the timeline) and the time span of the true investment yield.

3. Neglect to consider different payment types and signs.

The order is on purpose and by design, because it gives us the mnemonic indifferent that helps us easily remember the three TVM Rules. Below, instead of finding the “no-no” language, you’ll find a few minor and inert changes, including the words Time and Value and Money, to get you thinking about how the TVM Rules can also be remembered by recalling “Time,” “Value,” and “Money,” in that order:

1. Time: Consider money in different points in time.

2. Value: Correspond the time span in between periods or payments (on the timeline) and the time span of the true investment yield.

3. Money: Consider different payment types and signs.

Let’s once again reframe the TVM Rules, this time to include the five primary TVM financial calculator keys and the variables in the building block Time Value of Money equations:

1. N: money in different points in time.

2. i: correspond the time span in between periods or payments (on the timeline) (n) and the time span of the true investment yield; and

3. PV, PMT, and FV: consider different payment types and signs.

This is what I call the Time Value of Money trifecta!

How’s that for simplicity?

I’ll Take the Payment.

By Brent Pritchard

When you eat out, do you ask for your check or a bill? As far as I can tell, either appears to be correct. But for me, the word check has a positive vibe. There can be a negative connotation associated with the word bill. (Our oldest daughter is a waitress. I should ask her which is more common.) As it relates to the Mathematics of Finance, the word payment can, but need not, carry a negative connotation.

Some people, maybe those who ask for a bill in a restaurant, seem to think that there is only one way—think direction—to a payment. Like a two-way street, there are two ways to think about a payment when analyzing and evaluating real-world Time Value of Money situations.

Positive and negative. The different signs matter and inform which way the different payment types are flowing. For example, money received or withdrawn carries a positive (no sign) value, which denotes money coming into your hand. A negative sign denotes money leaving your hand, which is the case when money is invested or deposited.

Here’s an excerpt from my book Would Your Boomerang Return? What Birds, Hurdlers, and Boomerangs Can Teach Us About the Time Value of Money (2023):

There are two different payment types or classifications, and four different payment subclassifications. The acronym FAT, which stands for “Frequency, Amount, and Timing,” will help you tell what kind of payment you are dealing with. A payment with no frequency is called a single or lump-sum payment, which is represented by the variable PV or FV. When there’s frequency in the payment, you’re dealing with an even annuity, even perpetuity, uneven annuity, or uneven perpetuity. Amount and timing of the recurring payments tell you whether you’re dealing with an even annuity, even perpetuity, uneven annuity, or uneven perpetuity. A series of finite, even payments—even in terms of amount and timing—is considered an even annuity and represented with the variable PMT. An even perpetuity is a kind of even annuity with perpetual timing. When the number of the payments in the series is not even (equal) then you’re dealing with an uneven annuity. An uneven perpetuity has perpetual timing but payments that increase based on the growth rate (of inflation).

Negative signs only relate to certain TVM financial calculator inputs. Regardless of which way the money is flowing, you will always be working with positive (no sign) values for the variables PV, PMT, and FV in the building block Time Value of Money equations.

When did you first realize that three of the five primary TVM financial calculator keys are payment inputs, and that (positive and negative) signs matter?
