Policy (Text Block) [Abstract]
Basis of Presentation	The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ.
Investments	Investment securities principally include debt securities the Company classifies as available-for-sale and carries at fair value on the Consolidated Balance Sheets, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) (AOCI), net of income taxes. Realized gains and losses are recognized upon disposition of the securities using the specific identification method.
Contingencies	The Company has recorded reserves for certain of its outstanding legal proceedings. A reserve is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the recorded reserve. The Company evaluates, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the reserve that has been previously recorded, or a revision to the disclosed estimated range of possible losses, as applicable.
Derivatives	The Company uses derivative financial instruments (derivatives) to manage exposures to various market risks. These instruments derive their value from an underlying variable or multiple variables, including interest rates, foreign exchange rates, and equity index or price, and are carried at fair value on the Consolidated Balance Sheets. The changes in the fair value of derivatives that are not designated as hedges are intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures.
Guarantees	The Company’s recognition of these instruments is at fair value. In addition, the Company establishes reserves when a loss is probable and the amount can be reasonably estimated.

The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ.

Investments

Investment securities principally include debt securities the Company classifies as available-for-sale and carries at fair value on the Consolidated Balance Sheets, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) (AOCI), net of income taxes. Realized gains and losses are recognized upon disposition of the securities using the specific identification method.

Contingencies

The Company has recorded reserves for certain of its outstanding legal proceedings. A reserve is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the recorded reserve. The Company evaluates, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the reserve that has been previously recorded, or a revision to the disclosed estimated range of possible losses, as applicable.

Derivatives

The Company uses derivative financial instruments (derivatives) to manage exposures to various market risks. These instruments derive their value from an underlying variable or multiple variables, including interest rates, foreign exchange rates, and equity index or price, and are carried at fair value on the Consolidated Balance Sheets.

The changes in the fair value of derivatives that are not designated as hedges are intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures.

Guarantees

The Company’s recognition of these instruments is at fair value. In addition, the Company establishes reserves when a loss is probable and the amount can be reasonably estimated.
