investment in long-term growth opportunities.
Margins in this segment for 2013 were 7.8%, an increase of 40 basis points from 7.4% in 2012 driven by strong organic revenue growth and savings related to the Aon Hewitt restructuring program, partially offset by continued investment in long-term growth opportunities.
Unallocated Income and Expense A reconciliation of our operating income to income before income taxes is as follows (in millions):
## Table 0 ##
Unallocated operating expense includes corporate governance costs not allocated to the operating segments.
Net unallocated expenses remained relatively flat in 2013 compared to 2012.
Interest income represents income earned on operating cash balances and other income-producing investments.
It does not include interest earned on funds held on behalf of clients.
Interest income decreased $1 million, or 10%, from 2012, due to lower average interest rates globally and lower average cash balances.
Interest expense, which represents the cost of our worldwide debt obligations, decreased $18 million, or 8%, from 2012, which is primarily due to a decline in the average interest rate on total debt outstanding.
Other income increased $66 million from $2 million in 2012 to $68 million in 2013.
Other income in 2013 includes $28 million in gains on investments, equity earnings of $20 million, foreign exchange gains of $13 million, and $10 million in gains on disposal of businesses, partially offset by $10 million in losses from derivatives.
Other income in 2012 includes equity earnings of $13 million and $7 million gains on investments, partially offset by foreign exchange losses of $19 million.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES Our Consolidated Financial Statements and Notes thereto have been prepared in accordance with U. S.  GAAP.
To prepare these financial statements, we made estimates, assumptions and judgments that affect what we report as our assets and liabilities, what we disclose as contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the periods presented.
In accordance with our policies, we regularly evaluate our estimates, assumptions and judgments, including, but not limited to, those concerning revenue recognition, restructuring, pensions, goodwill and other intangible assets, contingencies, share-based payments, and income taxes, and base our estimates, assumptions, and judgments on our historical experience and on factors we believe reasonable under the circumstances.
The results involve judgments about the carrying values of assets and liabilities not readily apparent from other sources.
If our assumptions or conditions change, the actual results we report may differ from these estimates.
We believe the following critical accounting policies affect the more significant estimates, assumptions, and judgments we used to prepare these Consolidated Financial Statements.
Revenue Recognition Risk Solutions segment revenues primarily include insurance commissions and fees for services rendered and investment income on funds held on behalf of clients.
Revenues are recognized when they are earned and realized or realizable.
The Company considers revenues to be earned and realized or realizable when all of the following four conditions are met: (1) persuasive evidence of an arrangement exists, (2) the arrangement fee is fixed or determinable, (3) delivery or performance has occurred, and (4) collectability is reasonably assured.
For brokerage commissions, revenue is typically recognized at the completion of the placement process, assuming all other criteria required to recognize revenue have been met.
The placement process is typically considered complete on the effective date of the related policy.
Commission revenues are recorded net of allowances for estimated policy cancellations, which are determined based on an evaluation of historical and current cancellation data.
ILLUMINA, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Stock Options 2005 Stock and Incentive Plan In June 2005, the stockholders of the Company approved the 2005 Stock and Incentive Plan (the 2005 Stock Plan).
Upon adoption of the 2005 Stock Plan, issuance of options under the Company’s existing 2000 Stock Plan ceased.
Additionally, in connection with the acquisition of Solexa, the Company assumed stock options granted under the 2005 Solexa Equity Incentive Plan (the 2005 Solexa Equity Plan).
As of December 30, 2007, an aggregate of up to 13,485,619 shares of the Company’s common stock were reserved for issuance under the 2005 Stock Plan and the 2005 Solexa Equity Plan.
The 2005 Stock Plan provides for an automatic annual increase in the shares reserved for issuance by the lesser of 5% of outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year, 1,200,000 shares or such lesser amount as determined by the Company’s board of directors.
As of December 30, 2007, options to purchase 1,834,384 shares remained available for future grant under the 2005 Stock Plan and 2005 Solexa Equity Plan.

## Table 1 ##
PRUDENTIAL FINANCIAL, INC.  Notes to Consolidated Financial Statements 14.
EARNINGS PER SHARE (continued) Net income for the Financial Services Businesses and the Closed Block Business is determined in accordance with U. S.  GAAP and includes general and administrative expenses charged to each of the respective businesses based on the Company’s methodology for the allocation of such expenses.
Cash flows between the Financial Services Businesses and the Closed Block Business related to administrative expenses are determined by a policy servicing fee arrangement that is based upon insurance and policies in force and statutory cash premiums.
To the extent reported administrative expenses vary from these cash flow amounts, the differences are recorded, on an after tax basis, as direct equity adjustments to the equity balances of the businesses.
The direct equity adjustments modify the earnings available to each of the classes of common stock for earnings per share purposes.
Common Stock A reconciliation of the numerators and denominators of the basic and diluted per share computations is as follows:
## Table 2 ##
The Company’s convertible senior notes provide for the Company to issue shares of its Common Stock as a component of the conversion of the notes.
The notes will be dilutive to earnings per share if the average market price of the Common Stock for a particular period is above $90.00.
See Note 11 for additional information regarding the convertible senior notes.
For the years ended December 31, 2005, 2004 and 2003, 1.8 million, 4.5 million and 9.3 million options, respectively, weighted for the portion of the period they were outstanding, with a weighted average exercise price of $56.02, $44.94 and $31.66 per share, respectively, were excluded from the computation of diluted earnings per share because the options, based on application of the treasury stock method, were antidilutive.
Class B Stock Net income per share of Class B Stock was $119.50, $249.00 and $89.50 for the years December 31, 2005, 2004 and 2003, respectively
VORNADO REALTY TRUST NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 127 2.
Basis of Presentation and Significant Accounting Policies – continued Income Per Share: Basic income per share is computed based on weighted average shares outstanding.
Diluted income per share considers the effect of all potentially dilutive share equivalents, including outstanding employee stock options, restricted shares and convertible or redeemable securities.
Income Taxes: We operate in a manner intended to enable us to continue to qualify as a REIT under Sections 856-860 of the Internal Revenue Code of 1986, as amended.
Under those sections, a REIT which distributes at least 90% of its REIT taxable income as a dividend to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders.
We distribute to shareholders 100% of taxable income and therefore, no provision for Federal income taxes is required.
Dividends distributed for the year ended December 31, 2010, were characterized, for federal income tax income tax purposes, as 95.9% ordinary income, 2.8% as long term capital gain and 1.3% as return of capital.
Dividend distributions for the year ended December 31, 2009, were characterized, for Federal income tax purposes, as 63.9% ordinary income, 0.9% long-term capital gain and 35.2% return of capital.
Dividend distributions for the year ended December 31, 2008 were characterized, for Federal income tax purposes, as 70.8% ordinary income and 29.2% return of capital.
We have elected to treat certain consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries pursuant to an amendment to the Internal Revenue Code that became effective January 1, 2001.
Taxable REIT subsidiaries may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to Federal and State income tax at regular corporate tax rates.
Our taxable REIT subsidiaries had a combined current income tax liability of approximately $24,858,000 and $20,025,000 for the years ended December 31, 2010 and 2009, respectively, and have immaterial differences between the financial reporting and tax basis of assets and liabilities.
In connection with purchase accounting for H Street, in July 2005 and April 2007 we recorded an aggregate of $222,174,000 of deferred tax liabilities representing the differences between the tax basis and the book basis of the acquired assets and liabilities multiplied by the effective tax rate.
We were required to record these deferred tax liabilities because H Street and its partially owned entities were operated as C Corporations at the time they were acquired.
As of January 16, 2008, we had completed all of the actions necessary to enable these entities to elect REIT status effective for the tax year beginning on January 1, 2008.
Consequently, in the first quarter of 2008, we reversed the deferred tax liabilities and recognized an income tax benefit of $222,174,000 in our consolidated statement of income.
The following table reconciles net income attributable to common shareholders to estimated taxable income for the years ended December 31, 2010, 2009 and 2008.
