Prior to using this Web Site, Users must:
  1. in order to access publicly available data:

    2. important information about:
      1. Seller's next upcoming or most recently completed tax certificate sale (Auction Summary and Auction Details sections),
      2. data associated with the Seller's next upcoming or most recently completed tax certificate sale (Last Data Updates section),
      3. the order and schedule of Batch closings in upcoming and recently completed sales of selected tax certificates (the "Batch Schedule" section),
      4. contact information for Seller and GSG

Information provided on the Auction Summary Page is subject to change at any time at the Seller's discretion. To receive the most current information, the User can click the Reload button in the menu at the top of their browser page or the "refresh it now" link at the bottom of the page.

    1. Account Summary
      1. The Account Summary tab displays information on submitted and awarded bids, payments and budgets.

Acceptable forms of payment and deposit requirements are determined by Seller.
      3. Users must enter an amount in the Budget Input cell and click the 'Submit Budget' button before being permitted to submit Minimum Acceptable Rates.

Seller may require completion of changes to W-9s some minimum period of time in advance of auction commencement.
      2. If User has participated in an Auction by Seller in the past, User can look up the information on file with the Seller by entering the TIN and Bidder Number associated with the previous registration.

Bid Page:
  1. Information displayed on the Bid Page is current as of the "Last Update" time displayed on the Bid Page. The Bid Page does not automatically update itself. Users must click the Refresh button each time they want to update the Bid Page.
  2. Certificates displayed on the Bid Page correspond to the Certificate List and Batches displayed in the drop-down boxes near the top of the Bid Page.

Users can choose the number of certificates to display per page by selecting a value from the 'Number of Certificates to Display' drop-down box at the bottom of the Bid Page.
  3. Any selected Certificate List and Batch combination with more Certificates than the number selected in the 'Number of Certificates to Display' drop-down box will result in the display of one or more page number links (e.g., Page: 1 2 3 4 ...). Clicking any page number link enables Users to access additional Certificates on those pages.
  4. Users may see additional property and tax information for any particular certificate by clicking on the Account Number.
  5. Bidders establish Minimum Acceptable Rates for proxy bidding purposes by first inputting a rate in the 'Min. Rate' input boxes available for every certificate on the Bid Page, and then clicking either the "Submit" button for the corresponding Certificate or, to submit all entered rates simultaneously, clicking the "Submit All" Button near the top of the Bid Page. By clicking the "Submit All" button, Bidders submit all inputs that then appear in the 'Min. Rate' input cells related to the Certificate List and Batch displayed in the dropdown boxes at the top of the Bid Page at the time of submission. Correspondingly, rates may be submitted for certificates that are not displayed on the page being viewed by the Bidder if the list of certificates receiving rate submissions is longer than one page.
  6. Bidders must resolve Error message(s), if any, before erroneous submissions can be successfully retransmitted. Even when error messages are generated with respect to some submissions in a group (resulting from use of the Submit All feature, for example) and are consequently not transmitted, the portion of the submissions without errors are transmitted.
Information submitted on the Web Site is subject to the terms of the Privacy Policy.

Upload Page:
  1. The Upload Page allows Users to upload Minimum Acceptable Rates from a comma-separated values (CSV) file. These rates are not considered submitted until the User clicks the appropriate "Submit" or "Submit All" button on the Bid Page. Please see the section titled "Bids" for more information.

  3. To upload the completed Bid File, a User must click on the "Select File to Upload" button, locate the completed Bid File, then click the "Upload and Save" button.
  4. The system will process the completed Bid File and transfer the User to the Bid page, where the User's successfully processed rates will be entered in the appropriate "Min. Rate" cells.

Results Page:
  1. Results for auctions conducted on the Web Site can be viewed on the Results Page after the auction ends, and for participating bidders, after each Batch closes.

    4. Show Auction Summary

  4. All bids submitted for a particular certificate can be viewed in a separate window by clicking on the rate in the "Winning Bid" column.
  5. Results can be downloaded in an Excel or CSV file by clicking the Excel or CSV icons located on the page.
All results displayed on the Web Site are unofficial until certified by Seller.

General Information:

  1. A Batch is a group of two or more tax certificates to be auctioned that are grouped together and displayed in sequential order and that share the same bid submission deadline.
  2. Batches are a means of organizing tax certificates in a tax certificate sale. Each tax certificate in a Batch is auctioned off independently of every other tax certificate.
  3. The number of Batches and bid submission deadline for each Batch are disclosed on the Auction Summary Page, and can also be found in the Batch drop-down on the Bid Page.
  4. The number of certificates in any Batch and the interval between Batch closing times are disclosed on the Auction Summary Page.
The number of certificates in each Batch and the interval between Batches are determined by Seller.

  1. In order for Minimum Acceptable Rates (MARs) to be recorded, and used as the basis for bid submissions, rates must be entered by Users and received by the auction server on or before related and published Batch closing deadlines.
  2. Bidders' most recent MAR transmissions are displayed in the Submitted column.
  3. As explained above, Bidders may submit rates to purchase certificates with an aggregate face amount in excess of Bidders' Submitted Budget. However, at the point in time when the aggregate face amount of a Bidder's bids exceeds such Bidder's Submitted Budget, the remaining bids in excess of the Submitted Budget will be disregarded for purposes of determining a winning bidder.
  4. The Web Site includes a Proxy Bidding feature that permits users to enter the minimum interest rates they are willing to accept (which is entered in the 'Min. Rate' column of the Bid Page) for tax certificates they are bidding to purchase. The Web Site software (the "Software") will serve as Users' agent, or proxy, for submitting their bids. When bidding for a particular certificate ends (i.e. a Batch closes), the Software compares Bidder's MAR for a particular certificate with the best bid for that same certificate made on behalf of all other bidders. If a given Bidder's MAR is lower than the best bid submitted on behalf of all other bidders for the same certificate, the Software will automatically generate a bid on such Bidder's behalf that is 0.25% less than the next best bid. If there is a tie at the winning bid rate, the certificate will be awarded by the Software to one of the tie bidders through a random selection process using commercially available random number generation software.
  5. As it relates to Proxy Bidding requirements:
    1. Bidders may increase or decrease rates at any time prior to related Batch bid submission deadlines.
    2. Bidders may withdraw rates at any time prior to related Batch closing times by clicking the related "Withdraw" Button(s) on the Bid Page.
    3. Bidders may withdraw all Rates any time prior to the end of an auction by clicking the "Withdraw All" Button on the Bid Page and then clicking on the subsequent pop-up page to confirm the withdrawal of all bids.
    4. At no time before a Batch closing time will Bidders be permitted to see any other Bidder's bid. After Batches close, Bidders may view bidding results as explained above.
Errors and Messages:
  1. Any time the Software detects a Bidder error, the Bidder will receive:
    1. a brief description of the error in a yellow highlighted box near the top of the page, and
    2. if applicable, a yellow shaded identifier in the cell or area of the page in which the error occurred
  2. In order to remove an error description and, if applicable, yellow shaded identifier, the Bidder must either:
    1. correct the error and click the appropriate button on the page, or
    2. delete the error and click the appropriate button on the page, as applicable.
Erroneous entries and results are not successfully transmitted. Errors must be corrected before transmissions associated with such corrected error can be successfully completed. When a submission or transmission by a User contains errors, the portion of the transmission or submission, if any, that is unassociated with the error may be successfully transmitted or submitted.

Bids are processed in sequential order by Advertising Number instantly after each Batch closes and unofficial awards are made to Users with the lowest bid, provided the face amount of the certificate next to be awarded would not cause that User's cumulative award amount for all winning bids to exceed that same User's Submitted Budget. If a User's Submitted Budget would be exceeded by the award of a given certificate, the MAR entered by User will not qualify as a valid basis for Proxy Bidding on that certificate and hence will not result in a submitted bid or award under any circumstances. In other words, the associated Proxy Bid will be disregarded.
Awards displayed on the Results Page are unofficial until certified by the Seller.
