Understandability in financial statements means that the notes to the financial statement are simple and easily understandable, requiring users to be knowledgeable of technical terms and jargons.
Verifiability in financial statements means that the transactions are supported with documents, or if based on fair value, appraisers estimate the cost as verification.
Accounting Constraints are hindrances or impediments to achieving relevance and reliability of financial statements.
There are 3 Accounting Constraints:
Balance between Benefit & Cost
Balancing Qualitative Characteristics
True and Fair Presentation
In Balance between Benefit and Cost, Benefit of the information must exceed the cost of providing it. If it is the otherwise, the information may be excluded.
In BalancingQualitativeCharacteristics, relevance and reliability are affected. Relevant Information are reported on time while reliable information requires ample time. There should be balance between these two.
In True and Fair Presentation, true presentation requires inclusion of all economic transactions. While, fair presentation suggest that some data may be ommitted (those that don't have relevance in the decision of the users). In order to address tis constraint, the professional judgement of accountants are necessary, considering the materiality of each items and the nature of the transaction.
