- Definition
Amounts due from owners or affiliates of the reporting entity related to issuance of the entity's capital stock before cash payment is received (does not include amounts due from officers or directors). This element would also include the receivable for proceeds from the issuance of shares under employee stock option exercises which proceeds have not been received as of the reporting date due to the timing of the transaction date versus the settlement date.
