Alphabet Inc. (GOOG)

Cash, Cash Equivalents, and Marketable Securities

Alphabet invests all excess cash primarily in debt securities including those of the U.S. government and its agencies, corporate debt securities, mortgage-backed securities, money market and other funds, municipal securities, time deposits, asset backed securities, and debt instruments issued by foreign governments.

Alphabet classifies all investments that are readily convertible to known amounts of cash and have stated maturities of three months or less from the date of purchase as cash equivalents and those with stated maturities of greater than three months as marketable securities.

Alphabet determines the appropriate classification of the investments in marketable securities at the time of purchase and reevaluate such designation at each balance sheet date. Alphabet has classified and accounted for the marketable securities as available-for-sale. After consideration of the risk versus reward objectives, as well as the liquidity requirements, Alphabet may sell these securities prior to their stated maturities. As Alphabet views these securities as available to support current operations, Alphabet classifies highly liquid securities with maturities beyond 12 months as current assets under the caption marketable securities in the Consolidated Balance Sheets. Alphabet carries these securities at fair value, and reports the unrealized gains and losses, net of taxes, as a component of stockholders' equity, except for unrealized losses determined to be other-than-temporary, which Alphabet records within other income (expense), net. Alphabet determines any realized gains or losses on the sale of marketable securities on a specific identification method, and Alphabet records such gains and losses as a component of other income (expense), net.

Non-Marketable Investments

Alphabet accounts for non-marketable equity investments either under the equity or cost method. Investments through which Alphabet exercises significant influence but do not have control over the investee are accounted for under the equity method. Investments through which Alphabet is not able to exercise significant influence over the investee are accounted for under the cost method. Alphabet classifies non-marketable investments as non-current assets on the Consolidated Balance Sheet as those investments do not have stated contractual maturity dates.

Alphabet accounts for the non-marketable investments that meet the definition of a debt security as available-for-sale securities.
