"Established in 1973, it was created to reduce costs and provide efficiencies by immobilizing ecurities and making "book-entry" changes to show ownership of the securities. DTC moves securities for NSCC's net settlements, and settlement for institutional trades (which typically involve money and securities transfers between custodian banks and broker-dealers), as well as money market instruments. In 2007, DTC settled transactions worth $513 trillion, and processed 325 million book-entry deliveries. In addition to settlement services, DTC retains custody of 3.5 million securities issues, worth about $40 trillion, including securities issued in the US and more than 110 other countries. DTC is a member of the U.S. Federal Reserve System, and a registered clearing agency with the Securities and Exchange Commission.
Most large U.S. broker-dealers and banks are full DTC participants, meaning that they deposit and hold securities at DTC. DTC appears in an issuer’s stock records as the sole registered owner (as Cede & Co.) of securities deposited at DTC. DTC holds the deposited securities in “fungible bulk,” meaning that there are no specifically identifiable shares directly owned by DTC participants. Rather, each participant owns a pro rata interest in the aggregate number of shares of a particular issuer held at DTC. Correspondingly, each customer of a DTC participant, such as an individual investor, owns a pro rata interest in the shares in which the DTC participant has an interest.
Because the securities held by DTC are for the benefit of its participants and their customers (i.e., investors holding their securities at a broker-dealer), frequently the issuer and its transfer agent must interact with DTC in order to facilitate the distribution of dividend payments to investors, to facilitate corporate actions (i.e., mergers, splits, etc.), to effect the transfer of securities, and to accurately record the number of shares actually owned by DTC at all times"
"What are “chills” and “freezes” and why does DTC impose them? Occasionally a problem may arise with a company or its securities on deposit at DTC. In some of those cases DTC may impose a “chill” or a “freeze” on all the company’s securities. A “chill” is a restriction placed by DTC on one or more of DTC’s services, such as limiting a DTC participant’s ability to make a deposit or withdrawal of the security at DTC.
A chill may remain imposed on a security for just a few days or for an extended period of time depending upon the reasons for the chill and whether the issuer or transfer agent corrects the problem. A “freeze” is a discontinuation of all services at DTC. Freezes may last a few days or an extended period of time, depending on the reason for the freeze. If the reasons for the freeze cannot be rectified, then the security will generally be removed from DTC, and securities transactions in that security will no longer be eligible to be cleared at any registered clearing agency. Chills and freezes are monitored by DTC's Office of Regulatory Compliance (ORC) Unit.
DTC imposes chills and freezes on securities for various reasons. For example, DTC may impose a chill on a security because the issuer no longer has a transfer agent to facilitate the transfer of the security or the transfer agent is not complying with DTC rules in its interactions with DTC in transferring the security. Often this type of situation is resolved within a short period of time.
Chills and freezes can be imposed on securities for more complicated reasons, such as when DTC determines that there may be a legal, regulatory, or operational problem with the issuance of the security, or the trading or clearing of transactions involving the security. For example, DTC may chill or freeze a security when DTC becomes aware or is informed by the issuer, transfer agent, federal or state regulators, or federal or state law enforcement officials that an issuance of some or all of the issuer’s securities or transfer in those securities is in violation of state or federal law. If DTC suspects that all or a portion of its holdings of a security may not be freely transferable as is required for DTC services, it may decide to chill one or more of its services or place a freeze on all services for the security. When there is a corporate action, DTC will temporarily chill the security for book-entry activities. In other instances, a corporate action can cause a more permanent chill. This may force the issuer to reapply for eligibility altogether.
When DTC chills or freezes a security, it will issue a “Participant Notice” to its participants. These notices are publicly available on DTC’s website. When securities are frozen, DTC also provides optional automated notifications to its participants. These processes provide participants the ability to update their systems to automatically block future trading of affected securities, in addition to alerting participant compliance departments. DTC has information regarding these processes on its website."
