Thus, the full years of 2015 and 2014 and the period from December 9, 2013 to December 31, 2013 are comprised of the consolidated financial data of American and US Airways.
For the periods prior to December 9, 2013, the financial data reflects the results of American only.
For financial reporting purposes, the transaction constituted a transfer of assets between entities under common control and was accounted for in a manner similar to the pooling of interests method of accounting.
Under this method, the carrying amount of net assets recognized in the balance sheets of each combining entity are carried forward to the balance sheet of the combined entity and no other assets or liabilities are recognized.
The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements.

## Table 1 ##
(1) Yields are based on quarterly average carrying values except for fixed maturities, equity securities and securities lending activity.
Yields for fixed maturities are based on amortized cost.
Yields for equity securities are based on cost.
Yields for fixed maturities and short-term investments and cash equivalents are calculated net of liabilities and rebate expenses corresponding to securities lending activity.
Yields exclude investment income on assets other than those included in invested assets.
Prior periods yields are presented on a basis consistent with the current period presentation.
The decrease in yield on the Japanese insurance portfolio for 2009 compared to 2008 is primarily attributable to lower fixed maturity reinvestment rates, including the reinvestment of proceeds realized from certain capital actions and a lower short-term interest rate environment both in the U. S.  and Japan.
The U. S.  dollar denominated fixed maturities that are not hedged to yen through third party derivative contracts provide a yield that is substantially higher than the yield on comparable Japanese fixed maturities.
The average value of U. S.  dollar denominated fixed maturities that are not hedged to yen through third party derivative contracts for 2009 and 2008 was approximately $10.1 billion and $9.9 billion, respectively, based on amortized cost.
For additional information regarding U. S.  dollar investments held in our Japanese insurance operations see, “—Results of Operations for Financial Services Businesses by Segment— International Insurance and Investments Division.
” Fixed Maturity Securities Investment Mix Our fixed maturity securities portfolio consists of publicly-traded and privately-placed debt securities across an array of industry categories.
The fixed maturity securities relating to our international insurance operations are primarily comprised of foreign government securities.
We manage our public portfolio to a risk profile directed or overseen by the Asset Liability Management and Risk Management groups and, in the case of our international insurance portfolios, to a profile that also reflects the local market environment.
The investment objectives for fixed maturity securities are consistent with those described above.
The total return that we earn on the portfolio will be reflected both as investment income and also as realized gains or losses on investments.
We use our private placement and asset-backed portfolios to enhance the diversification and yield of our overall fixed maturity portfolio.
Within our domestic portfolios, we maintain a private fixed income portfolio that is larger than the industry average as a percentage of total fixed income holdings.
Over the last several years, our investment staff has directly originated more than half of our annual private placement originations.
Our origination capability offers the opportunity to lead transactions and gives us the opportunity for better terms, including covenants and call protection, and to take advantage of innovative deal structures.
