⁽¹⁾ Gains (losses) on deferred compensation plan investments, net: The gain (loss) on deferred compensation plan investments, which increases (decreases) deferred compensation expense included in operating income, is removed from operating income in the calculation because it is offset by an equal amount in investment income (loss) below net operating income on the income statement, and thus has no impact on net income attributable to the Company.

⁽²⁾ Net operating income, as adjusted: This non-GAAP measure was calculated by taking the Company's net operating income adjusted to exclude the impact on compensation expense of gains and losses on investments in the deferred compensation plan.

⁽³⁾ Tax provision on net operating income, as adjusted: This non-GAAP measure represents the tax provision excluding the impact of investment related activity and is calculated by applying the tax rate from the actual tax provision to net operating income, as adjusted.

⁽⁴⁾ Net operating income, as adjusted, after tax: This non-GAAP measure was calculated by taking the net operating income, as adjusted, less the tax provision on net operating income, as adjusted.

⁽⁵⁾ Net operating income, as adjusted after tax per diluted share: This non-GAAP measure was calculated by dividing the net operating income, as adjusted after tax, by diluted weighted average shares outstanding.

⁽⁶⁾ Operating profit margin, as adjusted: This non-GAAP measure was calculated by dividing the net operating income, as adjusted, by total revenue.
