NOTES TO THE AUDITED CONSOLIDATED FINANCIAL STATEMENTS 110 For 2007, 2006, and 2005, total share-based compensation expense (before tax) of approximately $26 million, $29 million, and $22 million, respectively, was recognized in selling, general and administrative expense in the consolidated statement of earnings for all share-based awards of which approximately $13 million, $17 million, and $5 million, respectively, related to stock options.
SFAS No.123(R) requires that compensation expense is recognized over the substantive vesting period, which may be a shorter time period than the stated vesting period for retirement-eligible employees.
For 2007 and 2006, approximately $3 million and $8 million, respectively, of stock option compensation expense were recognized due to retirement eligibility preceding the requisite vesting period.
Stock Option Awards Option awards are granted on an annual basis to non-employee directors and to employees who meet certain eligibility requirements.
Option awards have an exercise price equal to the closing price of the Company's stock on the date of grant.
The term life of options is ten years with vesting periods that vary up to three years.
Vesting usually occurs ratably over the vesting period or at the end of the vesting period.
The Company utilizes the Black Scholes Merton ("BSM") option valuation model which relies on certain assumptions to estimate an option's fair value.
The weighted average assumptions used in the determination of fair value for stock options awarded in 2007, 2006, and 2005 are provided in the table below:
## Table 0 ##
The volatility rate of grants is derived from historical Company common stock price volatility over the same time period as the expected term of each stock option award.
The volatility rate is derived by mathematical formula utilizing the weekly high closing stock price data over the expected term.
The expected dividend yield is calculated using the expected Company annual dividend amount over the expected term divided by the fair market value of the Company's common stock.
The average risk-free interest rate is derived from United States Department of Treasury published interest rates of daily yield curves for the same time period as the expected term.
SFAS No.123(R) specifies only share-based awards expected to vest be included in share-based compensation expense.
Estimated forfeiture rates are determined using historical forfeiture experience for each type of award and are excluded from the quantity of awards included in share-based compensation expense.
The weighted average expected term reflects the analysis of historical share-based award transactions and includes option swap and reload grants which may have much shorter remaining expected terms than new option grants.
Capital (This section should be read in conjunction with the Regulatory Matters section included in Part 1, Item 1 and Note 14 of the Notes to Consolidated Financial Statements. )
The following table presents risk-weighted assets and other financial data necessary to calculate certain financial ratios, including the Tier 1 common equity ratio, which we use to measure capital adequacy: Table 32 - Consolidated Capital Adequacy
## Table 1 ##
(1)Intangible assets are net of deferred tax liability and calculated assuming a 35% tax rate.
(2)Tangible equity, Tier 1 common equity, tangible common equity, and tangible assets are non-GAAP financial measures.
Additionally, any ratios utilizing these financial measures are also non-GAAP.
These financial measures have been included as they are considered to be critical metrics with which to analyze and evaluate financial condition and capital strength.
Other companies may calculate these financial measures differently.
Our Tier 1 common equity risk-based ratio improved 42 basis points to 10.90% at December 31, 2013, compared with 10.48% at December 31, 2012.
This increase primarily reflected the increase in retained earnings, partially offset by the repurchase of 16.7 million common shares and the impacts related to increased risk-weighted assets.
Net Income by Business Segment The segregation of net income by business segment for the past three years is presented in the following table: Table 34 - Net Income by Business Segment
## Table 2 ##
Treasury / Other The Treasury / Other function includes revenue and expense related to our insurance business, and assets, liabilities, and equity not directly assigned or allocated to one of the four business segments.
Other assets include investment securities and bank owned life insurance.
The financial impact associated with our FTP methodology, as described above, is also included.
Net interest income includes the impact of administering our investment securities portfolios and the net impact of derivatives used to hedge interest rate sensitivity.
Noninterest income includes insurance income, miscellaneous fee income not allocated to other business segments, such as bank owned life insurance income and any investment security and trading asset gains or losses.
Noninterest expense includes any insurance-related expenses, as well as certain corporate administrative, merger, and other miscellaneous expenses not allocated to other business segments.
The provision for income taxes for the business segments is calculated at a statutory 35% tax rate, though our overall effective tax rate is lower.
As a result, Treasury / Other reflects a credit for income taxes representing the difference between the lower actual effective tax rate and the statutory tax rate used to allocate income taxes to the business segments.
The $57.5 million, or 45%, year over year increase in net income for Treasury/Other was primarily the result of the FTP process described above.
The FTP process produced increased net income for Treasury/Other as the sustained low market interest rate environment, combined with a shift in funding mix to include additional wholesale sources, resulted in lower FTP credits paid to the business segments.
Optimal Customer Relationship (OCR) Our OCR initiative is a cross-business segment strategy designed to increase overall customer profitability and retention by deepening product and service penetration to consumer and commercial customers.
We believe this can be accomplished by taking our broad array of services and products and delivering them through a rigorous and disciplined sales management process that is consistent across all business segments and regions.
It is also supported by robust sales and cross-referral technology.
OCR was introduced in late 2009.
Through 2010, much of the effort was spent on defining processes, sales training, and systems development to fully capture and measure OCR performance metrics.
In 2011, we introduced OCR-related metrics for commercial relationships, which complements the previously disclosed consumer OCR-related metrics.
In 2013, we continue to experience strong consumer household and commercial relationship growth.
CONSUMER OCR PERFORMANCE For consumer OCR performance there are three key performance metrics: (1) the number of checking account households, (2) the number of product penetration per consumer checking household, and (3) the revenue generated from the consumer households of all business segments.
The growth in consumer checking account number of households is a result of both new sales of checking accounts and improved retention of existing checking account households.
The overall objective is to grow the number of households, along with an increase in product penetration.
