These variable interests arise from contractual, ownership or other monetary interests in the entities. The Company consolidates a VIE if it is the primary beneficiary, defined as the entity that has both the power to direct the activities that most significantly impact the VIE's economic performance and a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest the Company holds could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size and form of the Company's involvement with the VIE. The Company assesses whether or not it is the primary beneficiary of a VIE on an on-going basis. Investments in variable interest entities for which the Company is not considered the primary beneficiary are not consolidated and are accounted for as equity method or cost method investments. See Note 16 (Consolidation of Variable Interest Entity) for further discussion. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Non-controlling interest represents the equity interest not owned by the Company and is recorded for consolidated entities in which the Company owns less than 100% of the interests. Non-controlling interests are reported as a component of equity. In addition, changes in a parent's ownership interest while the parent retains its controlling interest are accounted for as equity transactions, and upon a gain or loss of control, retained ownership interests are remeasured at fair value, with any gain or loss recognized in earnings. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">The Company accounts for investments in common stock or in-substance common stock under the equity method of accounting when it has the ability to exercise significant influence over the investee, generally when it holds 20% or more of the common stock in the entity. MasterCard's share of net earnings or losses of entities accounted for under the equity method of accounting is included in other income (expense) on the consolidated statement of operations. The Company accounts for investments under the historical cost method of accounting when it does not exercise significant influence, generally when it holds less than 20% ownership in the common stock of the entity.

An entity shall disclose its policy for determining which items are treated as cash equivalents. Other information that may be disclosed includes (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value. Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and also effectively may withdraw fund s at any time without prior notice or penalty. In addition, cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. For a bank, may include explanation and amount of requirement to maintain reserves against deposits.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Financial Reporting Release (FRR) -Number 203 -Paragraph 02-03 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7, 8, 9, 10 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Technical Practice Aid (TPA) -Number 2110 -Paragraph 6 falsefalse9false0ma_RestrictedCashPolicyTextBlockmafalsenadurationRestricted Cash Policyfalsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1falsefalsefalse00<div> <div> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Restricted Cash</i>&#8212;The Company classifies cash as restricted when the cash is unavailable for withdrawal or usage.

Current accounting standards require companies to allocate revenue based on the fair value of each deliverable, even though such deliverables may not be sold separately either by the company itself or other vendors. The new accounting standard eliminates (i)&nbsp;the residual method of revenue allocation and (ii)&nbsp;the requirement that all undelivered elements must have objective and reliable evidence of fair value before a company can recognize the portion of the overall arrangement fee that is attributable to items that already have been delivered. The Company will adopt the revised accounting standard effective January&nbsp;1, 2011 via prospec tive adoption. The Company does not expect the adoption to have a material impact on the Company's financial position or results of operations. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Fair value disclosures</i>&#8212;In January 2010, fair value disclosure requirements were amended to require detailed disclosures about transfers to and from Level 1 and 2 of the Valuation Hierarchy effective January&nbsp;1, 2010 and disclosures regarding purchases, sales, issuances, and settlements on a "gross" basis within the Level 3 (of the Valuation Hierarchy) reconciliation effective January&nbsp;1, 2011.
