10.3 Permanent Differences Resulting From Share-Based Payment Awards
As indicated in ASC 718-740-25-3, recognition of compensation cost
                for share-based payments that “ordinarily do not result in tax deductions” do not
                give rise to deferred taxes for financial accounting purposes. In addition, excess
                tax benefits and tax deficiencies result in permanent differences between the amount
                of cumulative compensation cost recorded for equity-classified share-based payments
                and the amount of the corresponding tax deduction taken for tax purposes as
                discussed in Section
                    10.2.4.1. Other circumstances that result in permanent differences
                are discussed in the next sections.
        10.3.1 Equity- and Liability-Classified Awards That Do Not Ordinarily Result in a Tax Deduction
ASC 718-740-25-3 indicates that the cumulative amount of
                    compensation cost for awards that would not ordinarily result in a future tax
                    deduction under existing tax law does not represent a deductible temporary
                    difference. No deferred taxes would be recorded for these awards unless a change
                    in circumstances occurs. A common example of this type of an award is an ISO
                    (see Section 10.1).
                    When an entity issues an ISO, it will record compensation cost as the award is
                    earned but will not receive a tax deduction upon the holder’s exercise of the
                    award (i.e., a tax deduction will result only if the holder subsequently
                    disposes of the shares in a disqualifying disposition). Thus, the resulting book
                    expense is considered a permanent book-to-tax difference and will have the
                    effect of increasing the issuing entity’s ETR.
            10.3.2 Tax Benefits of Dividends on Share-Based Payment Awards
ASC 718-740
                                    Tax Benefits of
                                                Dividends on Share-Based Payment Awards to
                                                Employees
                                        45-8 An income tax benefit from
                                            dividends or dividend equivalents that are charged to
                                            retained earnings and are paid to grantees for any of
                                            the following equity classified awards shall be
                                            recognized as income tax expense or benefit in the
                                            income statement:
                                    - 
                                                  Nonvested equity shares
- 
                                                  Nonvested equity share units
- 
                                                  Outstanding equity share options.
As discussed further in Section 3.10 of Deloitte’s Roadmap
                        Share-Based Payment
                            Awards, the terms of some share-based payment awards
                    permit holders to receive a dividend during the vesting period and, in some
                    instances, to retain the dividend even if the award fails to vest. Such awards
                    are commonly referred to as “dividend-protected awards.” Dividend payments made
                    to grantees for dividend-protected awards should be charged to retained earnings
                    to the extent that the awards are expected to vest. If an employee is entitled
                    to retain dividends paid on shares that fail to vest, the dividend payment for
                    dividend-protected awards that are not expected to vest should be charged to
                    compensation cost.
                For income tax purposes, dividends paid on such awards may
                    result in a tax deduction and corresponding income tax benefit. The income tax
                    benefit resulting from payment of dividends on (1) nonvested equity shares, (2)
                    nonvested equity share units, and (3) outstanding equity share options should be
                    recorded as an income tax benefit in the income statement. If the dividend is
                    charged against retained earnings for pretax accounting purposes, a permanent
                    difference will result.
