You're a nice guy MKW but you are also very condescending at times. I don't know if you do it deliberately or not. Im here asking genuine questions Im not trying to troll. And you basically insult me as being thick when Im far far from that.
Now your answer is simply 'its GAAP'. So you haven't explained why its done this way then, as I said. You haven't looked at the logic of the situation, the similarity between the two examples. You just do what you're told. Which is fine, but don't come at me implying Im stupid for questioning how things are done when its illogical.
Sorry but if you want a full understanding of accounting I suggest you go and take a course.
If you want to understand asset valuation and why its done that way your going to need to.
Its a choice in life you either listen when people explain how something works or not, but arguing with them will typically see you branded an idiot.
"I told you not to touch those two wires" is very different to "Now I am going to say do not touch those two wires whilst I explain electricity from scratch"
Your examples are dog **** examples frankly, a semi absurd position on a cash account that makes no sense to accepted principles of how bonds work and are valued.
One point of GAAP is to stop dreamers making up asset values
The simple most basic valuation of any asset, no need to pull bonds out specifically, is they are worth what someone is willing to pay. Which generally for most asset classes is simple market value as it is widely available to all.
There is absolutely no reason why you would use a different valuation model for bonds when market value is available.
If you had some that were not widely traded then you would use a valuation model as I linked.
The point of a valuation is that it gives you something meaningful. A future value, unless performed on a whole portfolio is meaningless.
If I said you had a pension pot worth £1M and you went great I am liquidating it, and I sent you £200k you would go hang on you said its worth £1M.
If I said yeah it would be, it was all bonds dated 30+ years out that we valued at face value, you would be a little ****** wouldn't you?
Its why the term paper value, or paper profit/loss are what they are.
On paper your assets are worth £x if you paid more for them you have a paper loss.
On liquidation you have an actual or crystalised loss.
Until you actually liquidate something your profit/losses can go up or down.
You will say but my bind guarantees £x so I cannot lose money. In £ terms yes, but you are ignoring inflation and lost opportunity value of that being invested elsewhere.
Is your house worth £10k less because you may have to pay an estate agent to sell it?
