Gradually, over time I am fixing errors in my old accounts. I want to have a reasonably accurate record of investment performance and spending over time, I find solving the mysterious errors challenging, and I get to revisit different times in my life and remember what I was doing. I focus on the months with the biggest known errors. Today, it was the turn of September 2007, the month we moved to Australia. The accounts were pretty messed up. Finally, I worked out that either I was not paid back my security deposit in the US, or I received cash. I can't find any deposit in my bank accounts from the time. It was quite a crazy time, so maybe I just forgot? Intriguingly, in some handwritten accounts from then I recorded the deposit until the end of October and then just dropped it. I didn't mention it in the monthly report on this blog. I've now recorded it as an additional USD 600 of spending in September 2007.
The biggest remaining error in AUD terms is AUD 500 in October 2005 and in USD terms $684 in September 2020:
The error is defined as the difference between two different ways of computing the foreign currency component of the monthly change in net worth, which should be equal. This esoteric sounding error translates one to one into income or spending incorrectly recorded or transfers out of some accounts or investments not being matched by transfers into corresponding accounts. Once there were much more significant errors than these as there usually are now at the end of the month before I fix things.
