Special Purpose Acquisition Companies

A Fund may invest in stock, rights, warrants, and other securities of special purpose acquisition companies (“SPACs”) or similar special purpose entities. A SPAC is a publicly traded company that raises investment capital in the form of a blind pool via an IPO for the purpose of acquiring an existing company. The shares of a SPAC are typically issued in “units” that include one share of common stock and one right or warrant (or partial right or warrant) conveying the right to purchase additional shares or partial shares. At a specified time following the SPAC’s IPO (generally 1-2 months), the rights and warrants may be separated from the common stock at the election of the holder, after which the common stock, rights and warrants become freely tradeable. After going public and until an acquisition is completed, a SPAC generally invests the proceeds of its IPO (less a portion retained to cover expenses), which are held in trust, in U.S. government securities, money market securities and cash. To the extent the SPAC is invested in cash or similar securities, this may impact a Fund’s ability to meet its investment objective. If a SPAC does not complete an acquisition within a specified period of time after going public, the SPAC is dissolved, at which point the invested funds are returned to the SPAC’s shareholders (less certain permitted expenses) and any rights or warrants issued by the SPAC expire worthless or may be repurchased or retired by the SPAC at an unfavorable price.

Because SPACs and similar entities are in essence blank check companies without an operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable acquisition. Some SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. In addition, the securities issued by a SPAC, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

SPACs often have pre-determined time frames to make an acquisition (typically two years). In addition, as the number of SPACs grows, there is greater competition among SPACs and traditional purchasers of companies. These factors further increase the likelihood that SPAC sponsors may be incentivized to consummate acquisitions or mergers at less attractive valuations, as well as the risk that SPACs cannot successfully complete business combinations.

An investment in a SPAC is subject to a variety of risks in addition to those described above, including that: a significant portion of the funds raised by the SPAC for the purpose of identifying and effecting an acquisition or merger may be expended during the search for a target transaction; any proposed merger or acquisition may be unable to obtain the requisite approval, if any, of SPAC shareholders and/or antitrust and securities regulators; an acquisition or merger once effected may prove unsuccessful and an investment in the SPAC may lose value; the Fund may be delayed in receiving any redemption or liquidation proceeds from a SPAC to which it is entitled; an investment in a SPAC may be diluted by subsequent public or private offerings of securities in the SPAC or by other investors exercising existing rights to purchase securities of the SPAC; SPAC sponsors generally purchase interests in the SPAC at more favorable terms than investors in the IPO or subsequent investors on the open market; no or only a thinly traded market for shares of or interests in a SPAC may develop, leaving the Fund unable to sell its interest in a SPAC or to sell its interest only at a price below what the Fund believes is the SPAC security’s value; and the values of investments in SPACs may be highly volatile and may depreciate significantly over time.
