The gentleman above is Michael D Higgins, the Irish president – of course he is well known to me and other Irish people, but just for the benefit for others you might read my blog.
In October, there will be a presidential election and Michael D is up for a second term of office most likely. In recent months there has been a lot of media attention as of how much the presidential office costs to run. The office does not have much power, but is a great representation of Ireland as a country. According to the presidential website, the cost is about €3.6 million per annum. The vast majority of this consists of staff and travel costs. However, in various media outlets I have heard numbers being mentioned about the costs of the police officers and army associated with the presidential office. At the link above, these count for about €250,000 in 2017.
So what you say! Well, are these costs relevant to the cost of the presidential office? Would they be avoided if the office ceased to be? I doubt it, as the army and police would be put back to their normal duties. So this is a simple example of costs not bring relevant, and thus they probably should be excluded from any comments or analysis. I would guess too that the kind of simple analysis I have done here might be applied to many other political figures. What is probably most important though is that the costs of the office of the Irish president are now being discussed and new controls and checks may result – which is a good thing.
Okay, from my previous posts now you know a little about cryptography. And, you also know that bitcoin (and other cryptocurrencies) is managed decentrally. In the bitcoin system, transactions are verified as genuine (among other things) by cryptography – you can imagine how useless the system might be otherwise. This is achieved through a blockchain, which I will now explain briefly.
A block is essentially a transaction or group of transactions – in bitcoin, each block contains a megabyte of data (presently). When a block is full, a new block is added – hence the term blockchain. As blocks are added, the cryptography used links a block to the previous block. This means that the transactions can be verified all the way back to the original block, and it cannot be tampered with.
Also, I already wrote a little about bitcoin mining, and from that post, you can see that the blockchain for bitcoin is public – in effect a public distributed ledger of every bitcoin transaction that has ever happened.
What does blockchain mean or accountants then? Well to start, blockchain is a technology which is separable from things like bitcoin. It is the verifiable ledger that may be most appealing to business and the world of accounting. Businesses may soon be using blockchain in a less public way than bitcoin, using some form of private blockchain. Let me try to give an example of how accounting is done today, versus how it could be done with a blockchain.
I formerly worked in the paper business, in the cardboard packing part. Back then and still I would imagine, pharmaceutical companies would not allows recycled paper, due to the risk of contamination. The company I worked for had to maintain records to show the sources of all materials in an order for a pharmaceutical company. Just focusing on the accounting, there are four ledgers at play – the paper supplier, the cardboard manufacturer, the pharmaceutical company and the end vendor. All while four may have quite integrated systems within their own company, all four are likely not linked. And if they were linked, how can the truth and verifiability of the transactions be maintained. Here is where blockchain can help. Using a blockchain and its encrypted data, one single transaction can in theory flow through all four ledgers – and remain unchanged and verifiable. Also, the pharmaceutical company in this example can be sure that records are intact and full traceability of materials used maintained. This is just one example, and anything that involves traceability could benefit – I am sure auditors would have many uses for blockchain technology.
So where is the catch? If blockchain is used privately within a firm, then we can trust the hardware involved – no bitcoin miners needed. The catch at present is the energy usage. To solve the cryptography used in blockchain takes a lot of computing power and thus energy. At present, the energy used for bitcoin processing alone in a year is similar to the power consumption of a small country like Ireland. Less energy guzzling ideas are being worked on.
Following from the previous two posts, today I will explain cryptography in the simplest way I can – in reality, it is more complicated. However, a basic understanding is useful to appreciate blockchain – which will be the final post on this topic.
Cryptography is the art/task of creating and solving codes. Messages have been sent in code from centuries, and you can read a good summary of some methods here. The basic idea of cryptography is to render communications unreadable to the human eye by mixing up inputs (e.g. letters) to give a different output. One of the more famous uses of cryptography was the Enigma machine used by the German armed forces during WWII. The Enigma worked by scrambling letters into other letters and relied on the sending and receiving machines being set up the same. The set up was from three initial letters, resulting in over 17,576 (26^3) combinations. As you may know, it took a computer and some captured settings to break the Enigma code.
Move forward 70 years and a lot of information sent today over the internet uses some form of cryptography. There are two basic forms 1) encryption and 2) hashing. Encryption is what the Enigma did, an original message was scrambled on one end, sent via morse code, and de-scrambled on the other end. Hashing only involves scrambling. It uses an algorithm to derive a fixed length string which is different from the original text. A good example is a password. Passwords are usually not stored on servers in their original form, but as a hash value. If you enter a password, it is run through the algorithm and if it matches the stored hash value, you’re in. A commonly used hash is SHA256, which has 2^256 possible combinations – let’s just say that is a big number.
Encryption, as mentioned above, is a two-way thing. While I could write a lot more, let me try to keep it simple and explain the most common form, which is asymmetric encryption. First though, let us remind ourselves that encryption means some form of setup or code is needed, which is usually referred to as a key. In asymmetric encryption, there are two keys, a public key and a private key. Here is a simple example of how this works. Let’s say I want to send you an encrypted message. Your public key is sent out to anyone who may want to send messages to you. To send the message, I use your public key to encrypt it, so the message is secure when sent across any networks. When you receive the message, your private key unscrambles it. Only the combination of these pair of keys can do this, making the system quite secure. An example of an asymmetric encryption protocol (or set of rules) is TLS (Transport Layer Security) which is embedded within most operating systems and web browsers. It also offers 256 bit security, which is 2^256 – see more about TLS here. The current agreed TLS version is 1.2, and below you can see it is embedded within my version of Windows.
So, to sum up, encryption is complicated, but it is commonplace in our daily lives and apps. So can it be broken/cracked? Yes, but it would take a long long long time. See a great infographic below which details how long it would take to crack the code/cipher used in AES 256 – which is used by the TLS protocol mentioned above.
So now you know a little about cryptography, the next post in this series will cover blockchain.
In Part 1 two weeks ago, I wrote about currency. Here, I’ll explain how “miners” help a cryptocurrency like bitcoin be useable.
To be honest, I had no idea until recently what bitcoin mining actually means – and remember bitcoin is just one cryptocurrency, but I will use it here as an example.
Some weeks ago, I visited a friend of mine who owns and runs a technology maintenance firm. His office is always full of various parts of computers, but on this visit I noticed the office was quite warm and there was a hum of computer fans. So, I stuck my head around a corner and I seen something like what is in the picture above. So, joking I said, “what are you at now, mining bitcoin?”. “Yep” was the reply. So I took the opportunity to lean on my friend for some explanations.
The bottom line for me as an accountant, is that a “bit-coin mining rig” like that in the photo costs about €3,000 and can earn about €500 per month before energy costs – I will come back to these costs in a later post. So what the hell is it and what does it do I hear you ask? In my previous post, I established that bitcoin is not really a currency (yet) in the sense of dollars, euro or pounds. It also does not have a central bank behind it, or commercial banks taking it on board as a major currency. So this creates a problem, which in essence is if I want to pay you one bitcoin, how is this to be done – and remember bitcoin is an electronic medium, there are no paper notes.
Well, if I were to pay for a coffee with my credit/debit card, there is an extensive payments processing system behind the payment – think of the credit card machine, Visa/Mastercard/Amex systems and ultimately the retailer’s bank. Also, you may know that for every card transaction, the retailer is charged by the bank so they never get the full value of a card sale. For a bitcoin payment, where is the system? This is where the “miners” come in. A miner is someone who essentially processes bitcoin payments. My friend mentioned above told me the steps roughly are as follows:
- you get a rig (like the picture above). The faster the better, so rigs tend to use the fastest available memory cards – think about the graphics in a gaming console – these use really fast memory.
- Join a mining community
- Start solving hashes (encryption puzzles)- that is, process and verify bitcoin transactions. This includes working with blockchain, which will be explained in an upcoming post.
- Get a commission for each transaction
- Transfer the commission to a bitcoin wallet – for example, the Coinbase app
- Transfer to your bank account as you see fit.
So, in essence, a bitcoin miner like my friend is taking the place of the commercial banks and/or credit companies and processing payments. It is basically a form of distributed computing.
So from an accounting perspective what does this mean? Well, not very much actually. But, and this is a big but, would/could we trust people like my friend to effectively become a banking system. Personally, I am not sure. We have decades of regulation around our banking systems, and even with all the oversight, it still fails from time to time. The counter-argument could be something like the redundancy of systems or devolvement of the now rather central power of the banking and finance systems. But I’m not so sure just yet.
My next post will explain the basics of encryption.
I have been meaning to write something on blockchain for quite a while now. So, in this post and the next few, I will write what I hope are some simple lessons which will give you an appreciation of blockchain. To do this, I want to go back to some basics first and here I will remind you what a currency is. For these posts, I will use the example of a blockchain being used in cryptocurrencies, but there may be many other uses as time goes on.
So what is a currency? We probably all think we know what it is, it is the money in our pockets. That is a fair starting point, but we need to big a little deeper. In accounting – see for example the IASB’s Conceptual framework – there are several measurement bases: current cost, historic cost, present value, realisable value. The conceptual framework of the IASB defines measurement “as the process of determining the monetary amounts at which the elements of the financial statements are to be recognised and carried in the balance sheet and income statement”. Monetary means in money, and money can be defined as a current medium of exchange – hence the word currency. So, for accounting, this means we measure assets, liabilities, incomes and expenses in currency – a dollar, a euro, a pound. So why not in bitcoin, or litecoin or ethereum? Are these not currencies?
To answer these questions, let me divulge for a moment. When I was in secondary school, I studied “Business Studies”. From this, I remember something which used to be printed on all the Irish pound notes before we had the Euro, the term legal tender. I also recalled that all pound notes were legal tender, and a certain amount of coinage. Legal tender means that the currency is acceptable as a means of settling a debt. In Irish law, before the introduction of the Euro, a 1969 law set out that all notes and some coinage were legal tender e.g. a debt of £20 could be paid in coins of 10 pence or greater. The concept still applies to the Euro notes, and in other currencies too. However, being legal tender only means something is an acceptable means of payment, it does not have to be accepted in general. Thus, cheques, credit cards, PayPal, ApplePay, and guess what you got it, cryptocurrencies, do not have to be accepted as a form of payment. Having said that, typically banknotes are issued by a country’s central bank and are nearly always accepted.
So, if something is not legal tender, then there is a chance they may not be accepted as a method of payment (i.e. settlement of a debt). At this stage you are thinking, but if credit cards etc are not legal tender why are they so widely accepted? The answer lies in the fact that the banks who issue the cards and process payments are doing so typically in a currency recognised as legal tender.
Let me pose a question now. If you went to a typical shop in a town or city, and you had some cryptocurrency, maybe bitcoin, in an electronic wallet would you be able to pay for a coffee? The answer is generally no, but there are some online and other retailers who will accept payment in bitcoin. So it is probably fair to say that as bitcoin is not generally accepted (yet), it is not a currency. And, as far as I am aware, no cryptocurrency is yet legal tender. For accountants, this means that we are not yet measuring in cryptocurrency, and no accounting reports will be prepared in bitcoin for example. Thus in accounting terms, any cryptocurrency a business may have is treated as an asset in the financial statements – typically a current asset, like a normal bank or cash account. Of course, cryptocurrency values seem to be rather unstable, but this is not something I cover here.
Now that you know what a currency is, Part 2 of this series of posts will explore how bitcoin payments are processed.
I hope to write a few posts on this topic in the coming weeks, as we hear so much about blockchain and bitcoin and how it affects accounting/accountants. Before I do, this article in a great primer. For example, it relays the fact that bitcoin (for now) is an asset not a currency in accounting terms. Have a read, more to come soon.
Or a profit and loss account if you like the older term. Below is simple income statement (which has been published in the public domain), or more precisely an income and expense account, which is a term often used in clubs and charities. So, this example if not IFRS based, but the basic principles are the same. To be fair to the preparer of the statement below, it is quite detailed and transparent. But there is one problem – can you spot it? (“Einahment und Ausgaben” could translate as income and expenses or receipts and payments, but I will come back to this below).
Just to remind you, accounts are generally prepared using the accruals concept, but in smaller organisations like churches and charities, using a cash basis is common. Have you spotted what is seemingly incorrect? It is under the “expenditure heading”. Got it? It is the “repayment of loan”. This is a repayment of a capital item, or capital expenditure. Remember that only revenue expenditures appear as expenses in an income statement, so in the case of a loan only the interest on the loan would be included. So is the above statement incorrect? The answer is probably not, but now back to the nuances of language. The statement above is probably best described as a “receipts and payments” account, as it seems to be more representative of cash coming in and going out. We would need to have a chat with the preparer to be sure. However, including the loan repayment is a pointer that the above is not an income statement/profit and loss. This fits too with the nature of the organisation (a church).
You might also notice “reserves” on the income side of the statement above. Again, this is likely a capital item, and maybe should not be included as income. We would need more detail to be sure.
As you may know, there are public and private companies. Public companies can sell shares to members of the public, normally through a broker or exchange, private companies cannot. Both must prepare accounts though, and must also file certain accounting information which in turn becomes available to the public. So what accounting data can Joe Blogs get? The answer is it depends, but I will give you a good idea on this post.
In most European countries there is a central register of all companies – as far as I am aware the US does not have such a register, and the SEC focuses on public companies only. In Ireland and the UK, a small fee via an online portal gets me at least a balance sheet of a company – an abridged version for small companies – and an annual return which shows the directors and shareholders and their details (such as address). To give another example, in Germany I can download a free app called the Bundesanzeiger and search for details of any company – again for smaller companies I can get a summarised balance sheet.
For larger companies, including public a lot more information is available of course. But even with a balance sheet, or more of the company is medium or large, I can obtain quite a good picture of the financial position of a private company, and quite detailed information of directors and shareholders. Such information can be very useful to prospective investors, suppliers, customers and even employees. Why not search for a private company you know and see what you can find.
When I teach Activity-based costing (ABC), one of the example sectors often given to students is healthcare. Just in case you don’t know, ABC is a costing technique which allocates cost to products or services based on resources used by the product or service. If you think about healthcare, even in a standard medical procedure, no two patients are the same and use more or less drugs, time, hospital resources etc. Thus ABC appears useful – one patient may use more resources than the other and so cost more.
Of course, healthcare systems around the world vary. Some are fully funded by taxation, some are fully private. In Ireland, the system is mainly a public one, but unfortunately, it is not great in terms of access to treatment. So, if you can afford it, you can have private medical insurance (US style, but less costly) and this gives you more options. With this in mind, here is my recent experience which made me think about ABC and write this post.
Last year, I spent 11 days in a hospital for some heart surgery. Thankfully all is well. I am lucky enough to have health insurance. About three months post-surgery, I received an advice from my insurer stating how much the hospital had been paid – about €25,000. Phew, thankfully I did not have to find the cash for that! The advice was interesting in that showed little sign of ABC techniques – and as my hospital was one of the more advanced and modern I would have expected it to use ABC, to be honest. What the advice showed was a charge per day, with this charge being higher for two days in intensive care. Otherwise, there is little else. Unfortunately for me, I had some complications which required more drugs and attention from staff, so I took up more time and resources than some of my hospital mates (trust me, you make some good friends in hospitals). But this is not reflected in the cost. I suppose on balance things work out for the hospital and it may not matter, but to me, this simple example is a prime case where ABC could be used easily. If it were, then maybe health insurance costs would be a lot less in some cases – but that’s a whole other debate.
Having said all of the above, research on ABC use shows it is often less than 20% in practice. So maybe I should not be expecting its use in my hospital at all.
Ok, so I guess I will start with a caveat – I am not a fan of Elon Musk. He may be a great guy, I have never met him, but as an accountant, I see him as one of those entrepreneurs who may have good business ideas and models but they fail to turn them into profit. Tesla is a good example, and of course, I may eat my words in the future, but the company has yet to make any profitable product in a consistent manner – and they are on the third model of their car!
Looking at the Tesla 10K (which includes the financial statements) at the end of 2017, the accumulated losses are just under $5 billion. Okay, if we look at the balance sheet, the assets exceed liabilities, but some of the assets probably could lose value, or be over-valued, which would wipe any net assets. And okay, I get it that Tesla is breaking a mould, but they are not the only ones trying to make better cars. But, the company is 15 years old this year and still has accumulated losses; and the media reports production problems with the latest model still. And, it’s most recent quarter losses are about $700 million. So, let me ask this, would you invest in a company that cannot make a profit after 15 years? As an accountant, my verdict is no way!
If you have been in business, or work as an accountant, you’ll know cash is king. Of course, cash does not necessarily mean notes and coins, but cash in the bank. In my experience, getting cash from customers is not as easy and automated as one might think. There are always reasons why customers won’t pay – be it a quality issue, problems with services received or just being stubborn. But regardless of the reason, a business needs to get the cash in, otherwise, it WILL fail.
In my career, I have had the (dis)pleasure of sitting down once a month or so with a list of customers owing money. It’s great fun sometimes, and you get the “dog ate my homework type excuse”. One of the great excuses was ” we never got your invoice”, and today this would be retorted with “well it’s in your inbox now, so please pay”. And there may be some genuine excuses, like a family bereavement or lack of action on something like taking back returned goods or issuing a credit note. Or it may be as simple as your credit checks were not up to scratch. Regardless, whatever the reason or excuse, the best attitude is to be friendly but firm – or maybe professional is a good word. A guide from CPA Ireland equates getting paid by customers to getting your salary paid. This is a great analogy. The guide also emphasises the importance of communication, and this means not just with customers, but also with internal staff like sales people to try to determine why customer and not paying – unfortunately, the accounts receivable functions on most software I have ever seen never have the full story on why customers won’t pay.
I recently published a paper in Accounting History Review about a company called Bennett’s and their accounting in the early 1900s. This company provided malt, mainly to Guinness in Dublin. In the research for the article, it became apparent that producers of malt did not do very much management accounting. Bennett’s, for example, seemed not to cost their production process very often and seemed to accept the market price offered by breweries like Guinness.
One would thus think Guinness may have been in a strong position to dictate the price of malt, but this seemed not to be so. In an official corporate history of Guinness, a note is made of the fact that the malt providers should make a “living profit”. What this means is not defined, but when I read this I could only think of the contemporary idea of a “living wage”. This latter concept is to pay staff more than the minimum legal rates of pay (if there is one) and give them enough income to live – but not too much. I did a Google search for the term “living profit” and surprisingly – at least to me – there are no explanations or mentions. I cannot help but think that today the idea of a living profit could be applied in many supply chains, and indeed companies (and their shareholders) could ask themselves do they really need to make so much profit – think Apple, for example. I firmly believe history can teach us a lot, and this is one good example where some altered thinking might benefit society as a whole.
As you may know, many businesses incorporate – which means they are formed as a limited company. The are various types of company, but by far the most common is a private company. One of the key advantages of a company is that it is a separate legal entity, meaning it can sue and be sued in its own right. This means that individual shareholders and managers are protected in some ways and need not always bear the risks associated with the business.
However, you may also have heard the phrase “lifting the veil of incorporation”. Let me give you a recent example from personal experience. Where I live, a new residential development is proposed, and like all developments, it must go through a planning process with the local council. While looking at the development files, I noticed that the builder was a company and the designing architect another company. By coincidence, I noticed that the two companies were owned by the same person. This, as you can imagine, creates a bit of a problem in my mind. Then the owner of these two companies as a person submitted a document favourable to the proposed development. So, in eyes of the law, this is three people/bodies, but if we lift the veil of incorporation, we can see it is all the same people behind the entities.
Have a look at a new book I joint edited – here is the link
The book is a collection of 22 chapters on many aspects of Accounting Information Systems. It gives an excellent summary of current research and thought on AIS. Enjoy
Okay, it’s been a while, as I have been ill. But normal service is resumed 🙂
From previous posts, you’ll know I am a fan of cloud products and technology in general. I also study and write on change, so a recent experience with QuickBooks software (UK version) is great material for me.
I have been a QuickBooks (QB) customer since 2006 – before the cloud was widespread. I have had four desktop versions which in total earned about €1100 for Intuit. So at the end of December, I decide, let’s put this online. I signed up as an Irish customer (as I am based in Ireland, obvious one would think), created my company, and then went back to the desktop product (QB 2015 on my laptop) and ran an export to online company menu option. The end result was not as expected, I had two companies. As I signed on as an Irish customer, my data cannot be transferred from QB 2015 UK desktop version. So, I would have to subscribe in £ for a UK online account if I wish to have my data transferred.
So, what’s my point other than bad service – as I had no indication of what to do correctly online. Well:
- I am a very small business – what if I had a few thousand transactions a year I do not want to lose
- The change to online cloud accounting, while I like it, results in fewer features that accountants or clever managers like to use – for example, more detailed reporting. So would I want to then have a double sacrifice – lose my data and less reporting
Don’t get me wrong, the cloud is the way to go, but surely Intuit (and others) can do better!
