	Organization
	Green Dot Corporation (“we,” “us” and “our” refer to Green Dot Corporation and its wholly-owned subsidiaries) is a bank holding company with a mission to reinvent personal banking for the masses. Our prepaid products and services are available in more than 90,000 retail stores nationwide and online at Greendot.com. Our products include: Green Dot MasterCard and Visa-branded prepaid debit cards and several co-branded reloadable prepaid card programs, collectively referred to as our GPR cards; Visa-branded gift cards; our MoneyPak and swipe reload proprietary products, collectively referred to as our cash transfer products, which enable cash loading and transfer services through our Green Dot Network; and GoBank, an innovative checking account developed for use via mobile phones. GoBank is available online at GoBank.com and via the Apple App Store and Google Play. The Green Dot Network enables consumers to use cash to reload our prepaid debit cards or to transfer cash to any of our Green Dot Network acceptance members, including competing prepaid card programs and other online accounts.
	We market our products and services to banked, underbanked and unbanked consumers in the United States using distribution channels other than traditional bank branches, such as third-party retailer locations nationwide and the Internet. Our prepaid debit cards are issued by our wholly-owned subsidiary, Green Dot Bank and third-party issuing banks including The Bancorp Bank, Sunrise Banks, N.A., and prior to February 2014, GE Capital Retail Bank. We also have multi-year distribution arrangements with many large and medium-sized retailers, such as Walmart, Walgreens, CVS, Rite Aid, 7-Eleven, Kroger, Kmart, and Dollar Tree, and with various industry resellers, such as Blackhawk Network and Incomm. We refer to participating retailers collectively as our “retail distributors.”
	We completed a business acquisition during the six months ended June 30, 2014 which was not material to our consolidated financial statements. The aggregate cash consideration paid, net of cash acquired, was $14.9 million. Of the total consideration transferred, we allocated $3.3 million to goodwill and $17.4 million to acquired intangible assets. The intangible assets acquired will be amortized over their estimated useful lives of approximately 10 years.

	Summary of Significant Accounting Policies
	Basis of Presentation
	We have prepared the accompanying unaudited consolidated financial statements in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions.
	We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2013 for additional disclosures, including a summary of our significant accounting policies. There have been no changes to our significant accounting policies during the six months ended June 30, 2014. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for the six months ended June 30, 2014 are not necessarily indicative of future results.
	Recent Accounting Pronouncements
	In January 2014, the FASB issued ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (ASU 2014-04), which intends to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. ASU 2014-04 is effective for annual periods, and interim periods within those annual periods beginning after December 15, 2014. We will adopt this standard effective January 1, 2015. Our adoption of ASU 2014-14 is not expected to have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP.
	Note 2—Summary of Significant Accounting Policies (continued)
	The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard in 2017.

We do not intend to sell these investments and we have determined that it is more likely than not that we will not be required to sell these investments before recovery of their amortized cost bases, which may be at maturity.
	As of June 30, 2014, the contractual maturities of our available-for-sale investment securities were as follows:

	The expected payments on mortgage-backed and asset-backed securities may not coincide with their contractual maturities because the issuers have the right to call or prepay certain obligations.

	Credit Quality Indicators
	We closely monitor and assess the credit quality and credit risk of our loan portfolio on an ongoing basis. We continuously review and update loan risk classifications. We evaluate our loans using non-classified or classified as the primary credit quality indicator. Classified loans are those loans that have demonstrated credit weakness where we believe there is a heightened risk of principal loss, including all impaired loans. Classified loans are generally internally categorized as substandard, doubtful or loss, consistent with regulatory guidelines.
	The table below presents the carrying value, gross of the related allowance for loan losses, of our loans within the primary credit quality indicators related to our loan portfolio:

	Credit Quality Indicators
	We closely monitor and assess the credit quality and credit risk of our loan portfolio on an ongoing basis. We continuously review and update loan risk classifications. We evaluate our loans using non-classified or classified as the primary credit quality indicator. Classified loans are those loans that have demonstrated credit weakness where we believe there is a heightened risk of principal loss, including all impaired loans. Classified loans are generally internally categorized as substandard, doubtful or loss, consistent with regulatory guidelines.

	Income Taxes
	Income tax expense for the six months ended June 30, 2014 and 2013 differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. The sources and tax effects of the differences are as follows:
		Six Months Ended June 30,
		2014		2013
	U.S. federal statutory tax rate	35	%	35	%
	State income taxes, net of federal tax benefit	1.8		1.9
	General business credits	(1.1	)	(2.6	)
	Employee stock-based compensation	1.1		2
	Other	0.6		0.2
	Effective tax rate	37.4	%	36.5	%
	The effective tax rate for the
	six months ended June 30, 2014 and 2013 differs from the expected statutory federal income tax rate of 35% primarily due to state income taxes, net of federal tax benefit, general business credits and non-deductible employee stock based compensation. The increase in the effective tax rates for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 is primarily attributable to the expiration of general business credits on December 31, 2013. Additionally, we recognized a discrete benefit in the six months ended June 30, 2013 related to the reinstatement of 2012 general business credits.
	We establish a valuation allowance when we consider it more-likely-than-not that some portion or all of the deferred tax assets will not be realized. As of June 30, 2014, we did not have a valuation allowance on any of our deferred tax assets as we believed it was more-likely-than-not that we would realize the benefits of our deferred tax assets.
	Note 8—Income Taxes (continued)
	We are subject to examination by the Internal Revenue Service, or IRS, and various state tax authorities. Our consolidated federal income tax returns for the five-months ended December 31, 2009 and the years ended December 31, 2010 and 2011 are currently under examination by the IRS. We remain subject to examination of our federal income tax return for the year ended December 31, 2012. We generally remain subject to examination of our various state income tax returns for a period of four to five years from the respective dates the returns were filed.
	As of June 30, 2014, we have net operating loss carryforwards of approximately $29.7 million and $28.4 million for federal and state tax purposes, respectively, which will be available to offset future income. If not used, these carryforwards will expire between 2025 and 2031. In addition, we have state business tax credits of approximately $1.2 million that will expire between 2028 and 2033 and other state business tax credits of approximately $1.1 million that can be carried forward indefinitely. Certain limitations may be placed on net operating loss carryforwards as a result of changes in control as defined in Section 382 of the Internal Revenue Code. In the event a change in control occurs, it will have the effect of limiting the annual usage of the operating loss carryforwards.
	As of June 30, 2014 and 2013, we had a liability of $4.4 million and $2.7 million, respectively, for unrecognized tax benefits related to various federal and state income tax matters excluding interest, penalties and related tax benefits. The reconciliation of the beginning unrecognized tax benefits balance to the ending balance is as follows:
		Six Months Ended June 30,

	We recognized accrued interest and penalties related to unrecognized tax benefits as of June 30, 2014 of approximately $0.3 million. We did not have accrued interest or penalties related to unrecognized tax benefits as of June 30, 2013.

	In August 2013, the issued and outstanding shares of our Class B Common Stock declined to less than 10% of the aggregate number of issued and outstanding shares of our Class A Common Stock and Class B Common Stock. Pursuant to the terms of Article V of our Certificate of Incorporation, the issued and outstanding shares of our Class B common stock automatically converted into shares of our Class A common stock. Following this automatic conversion, there is now only a single class of our common stock outstanding. For the three and six months ended June 30, 2013, we grouped the components of Class B common stock basic earnings per common share, or EPS, and diluted EPS with Class A common stock, as if they were one class, to conform to the current period presentation. This regrouping did not impact EPS previously reported in this period.

	As of June 30, 2014, 368,052 shares of Class A common stock issued to Walmart were subject to our repurchase right. Basic and diluted EPS for these shares were the same as basic and diluted EPS for our Class A common stock for the three and six months ended June 30, 2014 and June 30, 2013.
	For the three and six months ended June 30, 2013, we excluded from the computation of basic EPS all shares issuable under an unvested warrant to purchase 4,283,456 shares of our Class A common stock, as the related performance conditions had not been satisfied.
	For the periods presented, we excluded all shares of convertible preferred stock and certain stock options outstanding, which could potentially dilute basic EPS in the future, from the computation of diluted EPS as their effect was anti-dilutive. The following table shows the weighted-average number of anti-dilutive shares excluded from the diluted EPS calculation:

	Fair Value Measurements
	Under applicable accounting guidance, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
	We determine the fair values of our financial instruments based on the fair value hierarchy established under applicable accounting guidance which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs used to measure fair value.
	For more information regarding the fair value hierarchy and how we measure fair value, see Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2013.
	As of June 30, 2014 and December 31, 2013, our assets carried at fair value on a recurring basis were as follows:

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The following describes the valuation technique for determining the fair value of financial instruments, whether or not such instruments are carried at fair value on our consolidated balance sheets.
	Short-term Financial Instruments
	Our short-term financial instruments consist principally of unrestricted and restricted cash and cash equivalents, federal funds sold, settlement assets and obligations, and obligations to customers. These financial instruments are short-term in nature, and, accordingly, we believe their carrying amounts approximate their fair values. Under the fair value hierarchy, these instruments are classified as Level 1.
	Investment Securities
	The fair values of investment securities have been derived using methodologies referenced in Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2013. Under the fair value hierarchy, our investment securities are classified as Level 2.
	Note 12—Fair Value of Financial Instruments (continued)
	Loans
	We determined the fair values of loans by discounting both principal and interest cash flows expected to be collected using a discount rate commensurate with the risk that we believe a market participant would consider in determining fair value. Under the fair value hierarchy, our loans are classified as Level 3.
	Deposits
	The fair value of demand and interest checking deposits and savings deposits is the amount payable on demand at the reporting date. We determined the fair value of time deposits by discounting expected future cash flows using market-derived rates based on our market yields on certificates of deposit, by maturity, at the measurement date.

	Commitments and Contingencies
	We monitor the laws of all 50 states to identify state laws or regulations that apply (or may apply) to prepaid debit cards. We have obtained money transmitter licenses (or similar such licenses) where applicable, based on advice of counsel or when we have been requested to do so. If we were found to be in violation of any laws and regulations governing banking, money transmitters, electronic fund transfers, or money laundering in the United States or abroad, we could be subject to penalties or could be forced to change our business practices.
	In the ordinary course of business, we are a party to various legal proceedings. We review these actions on an ongoing basis to determine whether it is probable that a loss has occurred and use that information when making accrual and disclosure decisions. We have not established reserves or possible ranges of losses related to these proceedings because, at this time in the proceedings, the matters do not relate to a probable loss and/or the amounts are not reasonably estimable.
	From time to time we enter into contracts containing provisions that contingently require us to indemnify various parties against claims from third parties. These contracts primarily relate to: (i) contracts with our card issuing banks, under which we are responsible to them for any unrecovered overdrafts on cardholders’ accounts; (ii) certain real estate leases, under which we may be required to indemnify property owners for environmental and other liabilities, and other claims arising from our use of the premises; (iii) certain agreements with our officers, directors, and employees, under which we may be required to indemnify these persons for liabilities arising out of their relationship with us; and (iv) contracts under which we may be required to indemnify our retail distributors, suppliers, vendors and other parties with whom we have contracts against claims arising from certain of our actions, omissions, violations of law and/or infringement of patents, trademarks, copyrights and/or other intellectual property rights.
	Generally, a maximum obligation under these contracts is not explicitly stated. Because the obligated amounts associated with these types of agreements are not explicitly stated, the overall maximum amount of the obligation cannot be reasonably estimated. With the exception of overdrafts on cardholders’ accounts, historically, we have not been required to make payments under these and similar contingent obligations, and no liabilities have been recorded for these obligations in our consolidated balance sheets.
	For additional information regarding overdrafts on cardholders’ accounts, refer to Note 4 — Accounts Receivable.

	Significant Customer Concentration
	A credit concentration may exist if customers are involved in similar industries, economic sectors, and geographic regions. Our retail distributors operate in similar economic sectors but diverse domestic geographic regions. The loss of a significant retail distributor could have a material adverse effect upon our card sales, profitability, and revenue growth.
	Revenues derived from our products sold at our four largest retail distributors represented the following percentages of our total operating revenues:
		Three Months Ended June 30,		Six Months Ended June 30,
		2014	2013	2014	2013
	Walmart	54%	65%	58%	66%
	Three other largest retail distributors, as a group	24%	22%	22%	22%
	Excluding stock-based retailer incentive compensation of $2.0 million for the three months ended June 30, 2014 and 2013, and $4.4 million and $3.6 million for the six months ended June 30, 2014 and 2013, respectively, revenues derived from our products sold at our four largest retail distributors represented the following percentages of our total operating revenues:
		Three Months Ended June 30,		Six Months Ended June 30,

	Walmart	55%	65%	58%	66%
	Three other largest retail distributors, as a group	22%	21%	22%	21%
	The concentration of GPR cards activated (in units) and the concentration of sales of cash transfer products (in units) derived from our products sold at our four largest retail distributors was as follows:
		Three Months Ended June 30,		Six Months Ended June 30,
		2014	2013	2014	2013
	Concentration of GPR cards activated (in units)	71%	85%	72%	84%
	Concentration of sales of cash transfer products (in units)	80%	87%	81%	88%
	Settlement assets derived from our products sold at our four largest retail distributors comprised the following percentages of the settlement assets recorded on our consolidated balance sheet:
		June 30, 2014	December 31, 2013
	Walmart	37%	34%
	Three other largest retail distributors, as a group	35%	39%
	Other concentrations
	At December 31, 2013, the customer funds underlying the Walmart co-branded GPR cards were held by GE Capital Retail Bank. These funds were held in trust for the benefit of the customers, and we had no legal rights to the customer funds. Additionally, we had receivables due from GE Capital Retail Bank that were included in accounts receivable, net, on our consolidated balance sheets.

	We have prepared the accompanying unaudited consolidated financial statements in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions.
	We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2013 for additional disclosures, including a summary of our significant accounting policies. There have been no changes to our significant accounting policies during the six months ended June 30, 2014. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for the six months ended June 30, 2014 are not necessarily indicative of future results.

	Recent Accounting Pronouncements
	In January 2014, the FASB issued ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors (ASU 2014-04), which intends to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. ASU 2014-04 is effective for annual periods, and interim periods within those annual periods beginning after December 15, 2014. We will adopt this standard effective January 1, 2015. Our adoption of ASU 2014-14 is not expected to have a material impact on our consolidated financial statements.
