@jpowell you have one more test to go, so i don't want to hear it! What helps me at work is going for a 15 min walk outside (kinda impossible since it's so hot now). Or i will sneak go in a break room, lay my head down and simply close my eyes. When your brain can truly check out for 10-15, it works wonders.
@Lstevens cumulative effect depends on how many prior years are presented with current year financial statements (for comparative purposes). If you're doing a retroactive change in principle for an entity switching from LIFO to FIFO, if they only present that year's statement, you adjust Retained Earning for the current year only. The entry would be to correct RE as if FIFO was used in all previous years.
If you have 2 previous years presented along with current year statements, you will need to adjust each year for it's cumulative effect. So Year 1, Year 2, and Current Year will need adjustments.
The entry would include a debit or credit to Retained Earnings. I don't know of a good example, but i do know you never touch any of the Income statement accounts because they're cleared out every year, your debit or credit to RE will already include them. You should only adjust Balance sheet accounts on the other side of the entry
