Notes to Consolidated Financial Statements 1.
Basis of Presentation The accompanying Consolidated Financial Statements and Notes thereto have been prepared in accordance with U. S.  generally accepted accounting principles ("U. S.  GAAP").
The Consolidated Financial Statements include the accounts of Aon plc and all of its controlled subsidiaries ("Aon" or the "Company").
All intercompany accounts and transactions have been eliminated.
The Consolidated Financial Statements include, in the opinion of management, all adjustments necessary to present fairly the Company's consolidated financial position, results of operations and cash flows for all periods presented.
Reclassification Certain amounts in prior years' Consolidated Financial Statements and related notes have been reclassified to conform to the 2015 presentation.
In prior periods, long-term investments were included in Investments in the Consolidated Statement of Financial Position.
These amounts are now included in Other non-current assets in the Consolidated Statement of Financial Position, as shown in Note 3 to these Consolidated Financial Statements.
Long-term investments were $135 million at December 31, 2015 and $143 million at December 31, 2014.
In prior periods, prepaid pensions were included in Other non-current assets in the Consolidated Statement of Financial Position.
These amounts are now separately disclosed in the Consolidated Statement of Financial Position.
Prepaid pensions were $1,033 million at December 31, 2015 and $933 million at December 31, 2014.
Upon vesting of certain share-based payment arrangements, employees may elect to use a portion of the shares to satisfy tax withholding requirements, in which case Aon makes a payment to the taxing authority on the employee’s behalf and remits the remaining shares to the employee.
The Company has historically presented amounts due to taxing authorities within Cash Flows From Operating Activities in the Consolidated Statements of Cash Flows.
The amounts are now included in “Issuance of shares for employee benefit plans” within Cash Flows From Financing Activities.
The Company believes this presentation provides greater clarity into the operating and financing activities of the Company as the substance and accounting for these transactions is that of a share repurchase.
It also aligns the Company’s presentation to be consistent with industry practice.
Amounts reported in Issuance of shares for employee benefit plans were $227 million, $170 million, and $120 million, respectively, for the years ended December 31, 2015, 2014 and 2013.
These amounts, which were reclassified from Accounts payable and accrued liabilities and Other assets and liabilities, were $85 million and $85 million in 2014, and $62 million and $58 million in 2013, respectively.
Changes to the presentation in the Consolidated Statements of Cash Flows for 2014 and 2013 were made related to certain line items within financing activities.
The following line items and respective amounts have been aggregated in a new line item titled “Noncontrolling interests and other financing activities” within financing activities.
## Table 0 ##
Use of Estimates The preparation of the accompanying Consolidated Financial Statements in conformity with U. S.  GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of reserves and expenses.
These estimates and assumptions are based on management's best estimates and judgments.
Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment.
Management believes its estimates to be reasonable given the current facts available.
Aon adjusts such estimates and assumptions when facts and circumstances dictate.
Illiquid credit markets, volatile equity markets, and foreign currency exchange rate movements increase the uncertainty inherent in such estimates and assumptions.
As future events and their effects cannot be determined, among other factors, with precision, actual results could differ significantly from these estimates.
Changes in estimates resulting from continuing changes in the economic environment would, if applicable, be reflected in the financial statements in future periods.
increase was partially offset by a 1.3% comparable store sales decline and the unfavorable effect of fluctuations in foreign currency exchange rates.
The components of the net revenue increase in fiscal 2009 were as follows:
## Table 1 ##
The 0.5% of revenue gross profit rate increase for fiscal 2009 was due to increases in both our Domestic and International segments’ gross profit rates.
The acquisition of Best Buy Europe increased our gross profit rate by 0.4% of revenue for fiscal 2009.
For further discussion of each segment’s gross profit rate changes, see Segment Performance Summary, below.
The 1.5% of revenue SG&A rate increase for fiscal 2009 was due to increases in both our Domestic and International segments’ SG&A rates.
The acquisition of Best Buy Europe increased our SG&A rate by 0.7% of revenue for fiscal 2009.
For further discussion of each segment’s SG&A rate changes, see Segment Performance Summary, below.
Our operating income in fiscal 2009 also included restructuring and goodwill and tradename impairment charges recorded in the fiscal fourth quarter.
The $78 million restructuring charge related primarily to employee termination benefits offered pursuant to voluntary and involuntary separation programs at our corporate headquarters and certain other locations.
The restructuring charges were recorded as a result of measures we took to create a more effective and efficient operating cost structure and to support our fiscal 2010 strategic priorities.
The $66 million goodwill and tradename impairment charges related to our Speakeasy business and were recorded as a result our annual goodwill impairment test.
Segment Performance Summary Domestic The following table presents selected financial data for our Domestic segment for each of the past three fiscal years ($ in millions):
## Table 2 ##
(1) Included within our Domestic segment’s operating income for fiscal 2010 is $25 million of restructuring charges recorded in the fiscal first quarter related to measures we took to update our U. S.  Best Buy store operating model.
These charges resulted in a decrease in our Domestic segment’s operating income of less than 0.1% of revenue for the fiscal year.
(2) Included within our Domestic segment’s operating income for fiscal 2009 is $72 million of restructuring charges recorded in the fiscal fourth quarter related to measures we took to restructure our businesses.
In addition, operating income is inclusive of goodwill and tradename impairment charges of $66 million related to our Speakeasy business.
Collectively, these charges resulted in a decrease in our Domestic segment’s operating income of 0.4% of revenue for the fiscal year.
Fiscal 2010 Results Compared With Fiscal 2009 The increase in our Domestic segment’s operating income for fiscal 2010 was due to higher gross profit dollars from net new store openings and comparable store sales growth, while SG&A dollars grew only 3.1% despite revenue growth of 6.4%, as shown by the decrease in the SG&A rate of 0.6% of revenue.
A decrease in restructuring and no goodwill and tradename impairment charges further contributed to the additional operating income.
The 6.4% revenue increase in fiscal 2010 resulted primarily from the net addition of 85 new stores during fiscal 2010 and a comparable store sales gain of 1.7%.
The components of the net revenue increase in the Domestic segment in fiscal 2010 were as follows:

(1) This exposure is all related to sub-prime mortgage loans.
Of the $825.7 million in gross unrealized losses as of December 31, 2012, there were $2.3 million in losses attributed to securities scheduled to mature in one year or less, $20.3 million attributed to securities scheduled to mature between one to five years, $4.1 million attributed to securities scheduled to mature between five to ten years, $251.7 million attributed to securities scheduled to mature after ten years and $547.3 million related to mortgage-backed and other ABS that are not classified by maturity year.
As of December 31, 2012, we were in a $2,966.9 million net unrealized gain position as compared to a $1,437.3 million net unrealized gain position as of December 31, 2011.
Of the $1,529.6 million increase in net unrealized gains for the year ended December 31, 2012, an approximate $0.2 billion increase can be attributed to an approximate 7 basis points decrease in interest rates in addition to other market factors that increased unrealized gains.
Fixed Maturities Available-for-Sale Unrealized Losses.
We believe that our long-term fixed maturities portfolio is well diversified among industry types and between publicly traded and privately placed securities.
Each year, we direct the majority of our net cash inflows into investment grade fixed maturities.
Our current policy is to limit the percentage of cash flow invested in below investment grade assets to 10% of cash flow.
During 2012, we did not actively increase our investment in available-for-sale below investment grade assets.
While Principal Life’s general account investment returns can improve due to the below investment grade asset class, we manage its growth strategically by limiting it to no more than 10% of the total fixed maturities portfolios.
We invest in privately placed fixed maturities to enhance the overall value of the portfolio, increase diversification and obtain higher yields than are possible with comparable quality public market securities.
Generally, private placements provide broader access to management information, strengthened negotiated protective covenants, call protection features and, where applicable, a higher level of collateral.
They are, however, generally not freely tradable because of restrictions imposed by federal and state securities laws and illiquid trading markets.
