Net asset value (NAV) is the value of an entity's assets minus the value of its liabilities, often in relation to open-end or mutual funds, since shares of such funds registered with the U.S. Securities and Exchange Commission are redeemed at their net asset value. This may also be the same as the book value or the equity value of a business. Net asset value may represent the value of the total equity, or it may be divided by the number of shares outstanding held by investors, thereby representing the net asset value ''per share''. Net asset value and other accounting and recordkeeping activities are the result of the process of fund accounting (also known as securities accounting, investment accounting, and portfolio accounting). Fund accounting systems are sophisticated computerized systems used to account for investor capital flows in and out of a fund, purchases and sales of investments and related investment income, gains, losses and operating expenses of the fund. The fund's investments and other assets are valued regularly; daily, weekly, or monthly, depending on the fund and associated regulatory or sponsor requirements. There is no universal method or basis of valuing assets and liabilities for the purposes of calculating the net asset value used throughout the world, and the criteria used for the valuation will depend upon the circumstances, the purposes of the valuation and any regulatory and/or accounting principles that may apply. For example, for U.S.-registered open-ended funds, investments are commonly valued each day the New York Stock Exchange is open, using closing prices (meant to represent fair value),〔AICPA Audit and Accounting Guide - Investment Companies May 1, 2007.〕 typically 4:00 p.m. Eastern Time. For U.S.-registered money market funds, investments are often carried or valued at "amortized cost" as opposed to market value for expedience and other purposes, provided various requirements are continually met.〔(【引用サイトリンク】publisher= Investment Company Institute )〕 At the completion of the valuation process and once all other appropriate accounting entries are posted, the accounting books are "closed" enabling a variety of information to be calculated and produced including the net asset value per share. ==Open-ended funds== Net asset value is most commonly used in the context of open-end funds. Shares and interests in such funds are not traded between investors, but are issued by the fund to each new investor and redeemed by the fund when an investor withdraws. A fund will issue and redeem shares and interests at a price calculated by reference to the NAV of the fund, with the intention that new investors receive a fair proportion of the fund and redeeming investors receive a fair proportion of the fund's value in cash. For example, if a fund has a NAV of $200 million and 1 million shares in issue on a certain day, the "NAV per share"—the price at which shares are issued—is $200. A person investing $40 million on that day will therefore be given 200,000 shares. Immediately following his investment the total NAV of the fund will be $240 million, as the new investor's cash becomes part of the fund and is available for investment by the fund. The investor will then be entitled to 1/6 of whatever the fund's value is when he withdraws his investment, if in the meantime his 1/6 ownership is not altered by any further withdrawals or investments to the fund. The valuation of the assets and liabilities of an open-ended fund is therefore very important to investors. If the NAV in the above example had, with the same assets, been calculated as $160 million (and the NAV per share as $160), the investor would have been given 250,000 shares and would become entitled to 1/5 of the fund's value. In contrast, closed-end funds are traded in the open market between investors and so the price of shares or interests in a closed-end fund will be whatever the parties agree it to be, which may not correspond to the fund's NAV. Publicly traded shares in such funds generally trade at a price below NAV. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「net asset value」の詳細全文を読む スポンサード リンク
