fair value measurement financial

"error was found in the fair value measurement"

A fair value measurement is an estimate of what an asset or liability could be sold for or transferred at in an orderly market, similar to getting a current market appraisal rather than the original purchase price. Investors care because it affects reported profits and a company’s balance sheet—changes in these estimates can move stock prices and signal shifts in the business, much like a real-time reappraisal of a home affects a homeowner’s net worth.

Monetary claims bought financial

"fair value measurement of Monetary claims bought"

Deferred tax liabilities financial

"Deferred tax liabilities decreased by ¥31,397 million"

An accounting entry that records taxes a company will likely have to pay in the future because the way profit is reported for investors (financial accounts) differs from how taxable income is calculated today. It matters to investors because it signals real future cash outflows that will reduce funds available for dividends, debt repayment or investment—think of it as a bill put on layaway that the company still must settle later, affecting valuation and financial strength.
