Significant Accounting Policies

Basis of consolidation and form of presentation

The Consolidated Financial Statements, prepared in conformity with GAAP, include the accounts of the Company and its subsidiaries. All significant intercompany transactions and balances have been eliminated.

Change in accounting principle

As discussed in Footnote 11 "Investments", as a result of the merger of BATS and Direct Edge Holdings LLC ("Direct Edge") in the first quarter of 2014, the Company changed its method of accounting for its investment in BATS from the cost method to the equity method.

Cash and cash equivalents

Cash and cash equivalents include money market accounts, which are payable on demand, and short-term investments with an original maturity of less than 90 days. The carrying amount of such cash equivalents approximates their fair value due to the short-term nature of these instruments. These assets would be categorized as Level 1 in the fair value hierarchy if they were required to be recorded at fair value.

Cash and cash equivalents segregated under federal and other regulations

The Company maintains custody of customer funds and is obligated by rules and regulations mandated by the U.S. Securities and Exchange Commission (“SEC”) and the Commodity Futures Trading Commission (“CFTC”) to segregate or set aside cash and/or qualified securities to satisfy these regulations, which have been promulgated to protect customer assets. The amounts recognized as Cash and cash equivalents segregated under federal and other regulations approximate fair value. These assets would be categorized as Level 1 in the fair value hierarchy if they were required to be recorded at fair value.

Market making, sales, trading and execution activities

Financial instruments owned and Financial instruments sold, not yet purchased relate to market making and trading activities, and include listed and other equity securities, listed equity options and fixed income securities that are recorded on a trade date basis and are reported at fair value. Trading revenues, net, which comprises trading gains, net of trading losses on such financial instruments, are also recorded on a trade date basis.

Commissions, which primarily comprise commission equivalents earned on institutional client orders and volume based fees earned from providing liquidity to other trading venues, as well as related expenses, are also recorded on a trade date basis. Prior to its sale in November 2014, commissions earned by the Company’s former FCM were recorded net of any commissions paid to independent brokers and were recognized on a half-turn basis.

The Company’s third party clearing agreements call for payment or receipt of interest income, net of transaction-related interest charged by such clearing brokers, for facilitating the settlement and financing of securities transactions. Interest income and interest expense which have been netted within Interest, net on the Consolidated Statements of Operations are as follows (in thousands):



	For the year ended December 31,
	2015			2014			2013
Interest Income	$	12,666		$	14,363		$	10,187
Interest Expense	(14,794		)	(13,742		)	(10,724		)
Interest, net	$	(2,128	)	$	621		$	(537	)

Dividend income relating to financial instruments owned and dividend expense relating to financial instruments sold, not yet purchased, are derived primarily from the Company’s market making activities and are included as a component of Trading revenues, net on the Consolidated Statements of Operations. Trading revenues, net includes dividend income and expense as follows (in thousands):



	For the year ended December 31,
	2015			2014			2013
Dividend Income	$	63,971		$	45,910		$	26,237
Dividend Expense	$	(42,398	)	$	(38,444	)	$	(21,630	)

Payments for order flow represent payments to broker dealer clients, in the normal course of business, for directing their order flow in U.S. equities and options to the Company.

Fair value of financial instruments

The Company values its financial instruments using a hierarchy of fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value.

The fair value hierarchy can be summarized as follows:


•	Level 1—Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.


•	Level 2—Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.


•	Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

Changes in fair value are recognized in earnings each period for financial instruments that are carried at fair value. See Footnote 6 “Fair Value” for a description of valuation methodologies applied to the classes of financial instruments at fair value.

Collateralized agreements and financings

Collateralized agreements consist of securities borrowed. Collateralized financings include securities loaned and financial instruments sold under agreements to repurchase.

•

Securities borrowed and securities loaned transactions are recorded at the amount of cash collateral advanced or received. Securities borrowed transactions facilitate the securities settlement process and require the Company to deposit cash or other collateral with the lender. Securities loaned transactions help finance the Company’s securities inventory whereby the Company lends stock to counterparties in exchange for the receipt of cash or other collateral from the borrower. In these transactions, the Company receives or posts cash or other collateral in an amount generally in excess of the market value of the applicable securities borrowed or loaned. The Company monitors the market value of securities borrowed or loaned on a daily basis, and obtains additional collateral or refunds excess collateral as necessary.

•

Financial instruments sold under agreements to repurchase are used to finance inventories of securities and other financial instruments and are recorded at their contractual amount. The Company has entered into bilateral and tri-party term and overnight repurchase agreements which bear interest at negotiated rates. The Company receives cash and makes delivery of financial instruments to a custodian who monitors the market value of these instruments on a daily basis. The market value of the instruments delivered must be equal to or in excess of the principal amount loaned under the repurchase agreements plus the agreed upon margin requirement. The custodian may request additional collateral, if appropriate.

The Company’s securities borrowed, securities loaned and financial instruments sold under agreements to repurchase are recorded at amounts that approximate fair value. These items are recorded based upon their contractual terms and are not materially sensitive to shifts in interest rates because they are short-term in nature and are substantially collateralized pursuant to the terms of the underlying agreements. These items would be categorized as Level 2 in the fair value hierarchy if they were required to be recorded at fair value.

Investments

Investments primarily comprise noncontrolling equity ownership interests in financial services-related businesses and are held by the Company's non-broker dealer subsidiaries. These investments are accounted for under the equity method, at cost or at fair value. The equity method of accounting is used when the Company has significant influence over the operating and financial policies of the investee. Investments are held at cost, less impairment if any, when the investment does not have a readily determined fair value, and the Company is not considered to exert significant influence over operating and financial policies of the investee. Investments that are publicly traded are held at fair value and accounted for as available for sale securities on the Consolidated Statements of Financial Condition.

Prior to the Mergers, GETCO had a strategic investment in Knight which was classified as available for sale and held at fair value with any unrealized gains or losses recorded in Other comprehensive income or loss. As a result of the Mergers, the Company recognized a non-cash gain of $128.0 million on its investment in Knight Common Stock, which it recorded within Investment income and other, net on the Consolidated Statement of Operations for the year ended December 31, 2013 and reversed any previous unrealized gains out of Other comprehensive income.

Investments are reviewed on an ongoing basis to ensure that the carrying values of the investments have not been impaired. If the Company determines that an impairment loss on an investment has occurred due to a decline in fair value or other market conditions, the investment is written down to its estimated fair value.

Included in the Company's investments are assets supporting a non-qualified deferred compensation plan for certain employees. This plan provides a return to the participants based upon the performance of various investments. In order to hedge its liability under this plan, the Company generally acquires the underlying investments and holds such investments until the deferred compensation liabilities are satisfied. Changes in value of such investments are recorded in Investment income and other, net, with a corresponding charge or credit to Employee compensation and benefits on the Consolidated Statements of Operations. Deferred compensation investments primarily consist of mutual funds, which are accounted for at fair value.

Goodwill and intangible assets

The Company tests goodwill and intangible assets with an indefinite useful life for impairment annually or when an event occurs or circumstances change that signifies that the carrying amounts may not be recoverable. The Company amortizes intangible assets with a finite life on a straight line basis over their estimated useful lives and tests for recoverability whenever events indicate that the carrying amounts may not be recoverable. The Company capitalizes certain costs associated with the acquisition or development of internal-use software and amortizes the software over its estimated useful life of three years, commencing at the time the software is placed in service.

Payable to customers

Payable to customers primarily relate to amounts due on cash and margin transactions. Due to their short-term nature, such amounts approximate fair value.

Repurchases of common stock

The Company may repurchase shares of KCG Class A Common Stock in the open market or through privately negotiated transactions. The Company may structure such repurchases as either a purchase of treasury stock or a retirement of shares. The Company records its purchases of treasury stock, which include shares repurchased in satisfaction of tax withholding obligations upon vesting of restricted awards, at cost as a separate component of stockholders’ equity. The Company may re-issue treasury stock, at average cost, for the acquisition of new businesses and in certain other circumstances. For shares that are retired, the Company records its repurchases at cost, as a reduction in Class A Common Stock for the par value of such retired shares and a reduction in Retained earnings for the balance.

Repurchases of warrants

The Company may repurchase KCG Warrants through privately negotiated transactions. The Company records its purchases as a reduction in Additional paid-in capital for the total cost.

Foreign currency translation and foreign currency forward contracts

The Company's foreign subsidiaries generally use the U.S. dollar as their functional currency. The Company has a subsidiary in India that utilizes the Indian Rupee as its functional currency.

Assets and liabilities of the Indian subsidiary are translated at exchange rates at the end of a period. Revenues and expenses are translated at average exchange rates during the period. Gains and losses resulting from translating foreign currency financial statements into U.S. dollars are included in Accumulated other comprehensive income on the Consolidated Statements of Financial Condition and Cumulative translation adjustment, net of tax on the Consolidated Statements of Comprehensive Income.

Gains or losses resulting from foreign currency transactions are included in Investment income and other, net on the Company’s Consolidated Statements of Operations. For the years ended December 31, 2015, 2014 and 2013, the Company recorded losses of $0.7 million, $2.0 million and $4.1 million, respectively on foreign currency transactions.

The Company seeks to reduce the impact of fluctuations in foreign exchange rates on its net investment in certain non-U.S. operations through the use of foreign currency forward contracts. For foreign currency forward contracts designated as hedges, the Company assesses its risk management objectives and strategy, including identification of the hedging instrument, the hedged item and the risk exposure and how effectiveness is to be assessed prospectively and retrospectively. The effectiveness of the hedge is assessed based on the overall changes in the fair value of the forward contracts. For qualifying net investment hedges, any gains or losses, to the extent effective, are included in Accumulated other comprehensive income on the Consolidated Statements of Financial Condition and Cumulative translation adjustment, net of tax, on the Consolidated Statements of Comprehensive Income. The ineffective portion, if any, is recorded in Investment income and other, net on the Consolidated Statements of Operations.

Stock and unit based compensation

Stock and unit based compensation is primarily measured based on the grant date fair value of the awards. These costs are amortized over the requisite service period, if any. Expected forfeitures are considered in determining stock-based employee compensation expense. See Footnote 15 "Stock-Based Compensation" for further discussion.

Soft dollar expense

Under a commission management program, the Company allows institutional clients to allocate a portion of their gross commissions to pay for research and other services provided by third parties. As the Company acts as an agent in these transactions, it records such expenses on a net basis within Commissions and fees on the Consolidated Statements of Operations.

Depreciation, amortization and occupancy

Fixed assets are depreciated on a straight-line basis over their estimated useful lives of three to seven years. Leasehold improvements are being amortized on a straight-line basis over the shorter of the term of the related office lease or the expected useful life of the assets. The Company reviews fixed assets and leasehold improvements for impairment and their remaining useful lives whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable.

The Company recognizes rent expense under operating leases with fixed rent escalations, lease incentives and free rent periods on a straight-line basis over the lease term beginning on the date the Company takes possession of or controls the use of the space, including during free rent periods.

Lease loss accrual

The Company’s policy is to identify excess real estate capacity and where applicable, accrue for related future costs, net of projected sub-lease income upon the date the Company ceases to use the excess real estate. Such accrual is adjusted to the extent the actual terms of sub-leased property differ from the assumptions used in the calculation of the accrual.

Income taxes

The Company is a corporation subject to U.S. corporate income tax as well as non-U.S. income taxes in the jurisdictions in which it operates. The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and measures them using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The Company evaluates the recoverability of future tax deductions by assessing the adequacy of future expected taxable income from all sources, including reversal of temporary differences and forecasted operating earnings.

Variable interest entities

A variable interest entity (“VIE”) is an entity that lacks one or more of the following characteristics (i) the total equity investment at risk is sufficient to enable the entity to finance its activities independently and (ii) the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity.

The Company will be considered to have a controlling financial interest and will consolidate a VIE if it has both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE.

Since January 2015, the Company has owned 50% of the voting shares and 50% of the equity of a joint venture, (“JV”) which maintains microwave communication networks in the U.S. and Europe, and is considered to be a VIE. The Company and its JV partner each use the microwave communication networks in connection with their respective trading activities, and the JV sells excess bandwidth that is not utilized by the JV members to third parties. The Company pays the JV for the communication services that it uses, and such amounts are recorded within Communications and data processing on the Consolidated Statements of Operations.

The Company does not have the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; therefore it does not have a controlling financial interest in the JV and does not consolidate the JV. The Company records its interest in the JV under the equity method of accounting and records its investment in the JV within Investments and its amounts payable for communication services provided by the JV within Accrued expenses and other liabilities on the Consolidated Statements of Financial Condition. The Company records its pro-rata share of the JV’s earnings or losses within Investment income and other, net and communication services provided by the JV within Communications and data processing on the Consolidated Statements of Operations.

The Company’s exposure to the obligations of this VIE is generally limited to its interests in the JV, which is the carrying value of the equity investment in the JV.

The following table presents the Company’s nonconsolidated VIE at December 31, 2015 (in thousands):



	Carrying Amount				Maximum Exposure to loss
	Asset		Liability		Maximum Exposure to loss		VIE's assets
Equity investment	$	10,632	$	5	$	10,632	$	22,197

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

Recently adopted accounting guidance

In April 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standard Update (“ASU”) that amends the requirements for reporting discontinued operations. Under the new guidance, discontinued operations reporting are limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. The updated guidance is effective prospectively to all disposals occurring for interim and annual reporting periods beginning after December 15, 2014, with early adoption permitted. The Company early adopted this ASU in 2014, which resulted in additional disclosures within the Company's Consolidated Financial Statements.

In June 2014, the FASB issued an ASU that amends the accounting and disclosure guidance on repurchase agreements. The amended guidance requires entities to account for repurchase-to-maturity transactions as secured borrowings. Additional disclosures will be required for the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The accounting changes and additional disclosures about certain transferred financial assets accounted for as sales were effective for reporting periods beginning after December 15, 2014. The additional disclosures for securities financing transactions are required for annual reporting periods beginning after December 15, 2014 and for interim reporting periods beginning after March 15, 2015. Other than additional disclosure requirements, the adoption of this ASU did not have an impact on the Company’s Consolidated Financial Statements.

Recent accounting guidance to be adopted in future periods

In May 2014, the FASB issued an ASU that updates the principles for recognizing revenue. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted for reporting periods beginning after December 15, 2016. The Company is evaluating the impact of this ASU on its Consolidated Financial Statements.

In June 2014, the FASB issued an ASU to resolve diverse accounting treatment for share based awards in which the terms of the award are related to a performance target that affects vesting. The ASU requires an entity to treat a performance target that could be achieved after the requisite service period as a performance condition. Additionally, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved, and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered; if the performance target becomes probable of being achieved before the end of the requisite service period, then the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The guidance is effective for reporting periods beginning after December 15, 2015 and may be applied prospectively or retrospectively. The Company does not expect adoption of this ASU to have an impact on its Consolidated Financial Statements.

In August 2014, the FASB issued an ASU that requires an entity’s management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The guidance is effective for reporting periods beginning after December 15, 2016. Other than additional disclosure requirements, the Company does not expect the adoption of this ASU to have an impact on its Consolidated Financial Statements.

In February 2015, the FASB issued an ASU which requires entities to evaluate whether they should consolidate certain legal entities. The ASU simplifies consolidation accounting by reducing the number of consolidation models that an entity may apply. The guidance is effective for reporting periods beginning after December 15, 2015 and early adoption is permitted. The Company does not expect the adoption of this ASU to have an impact on its Consolidated Financial Statements.

In April 2015, the FASB issued an ASU regarding simplification of the presentation of debt issuance costs. The ASU requires that debt issuance costs related to a recognized debt liability be presented in the Consolidated Statements of Financial Condition as a direct deduction from the carrying amount of that debt liability. The guidance is effective retrospectively for reporting periods beginning after December 15, 2015 and early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company's Consolidated Financial Statements.

In January 2016, the FASB issued an ASU that provides entities guidance for the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. The guidance is effective for reporting periods beginning after December 15, 2018 and early adoption is permitted under a modified retrospective approach for certain financial liabilities as specified in this ASU. The Company is evaluating the impact of this ASU on its Consolidated Financial Statements.
