This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents commitments outstanding as of the balance sheet date which obligate or represent potential claims against the assets of the Company relating to, for example, the extension of credit. Further, commitments generally represent off balance sheet arrangements that obligate the entity to deliver assets or services or enter into another obligation in the future.
