There are three main types of phantom facts that require tagging in non-printing sections. The first type of phantom fact is when a value is expressed parenthetically in a table cell in one of the financial statements. Since cells can only be linked as a whole for the primary fact presented, a secondary value that forms only part of the information presented in a cell must be phantom tagged.
The second is when a single value is represented by two different dates. Since each link can only contain one XBRL fact, the fact for the second date must be phantom tagged.
Phantom tagging is required when a value is represented by a word instead of a numeral such as writing out the word "four" or using a word with numeric implications such as "none" or "no".
Tagging Parenthetical Values
A parenthetical is any value that lies within a line item description on the face financial statements, and must be tagged individually. Each parenthetical table should be created in a non-printing section of your document. We recommend adding non-printing sub-sections to the section of your document containing the associated parenthetical information.
Below is an example of the parentheticals you may see in the Balance Sheet:
A parenthetical template is available for import into your Wdesk account. Please contact your Customer Success Manager to obtain one. You can also create one manually as shown in the example below:
Once the parenthetical table is set up, we can now setup the XBRL Outline:
1. With XBRL turned on, select a cell in the table and then enter Table Focus Mode from the Actions menu.
Since this table has not been tagged with XBRL, you will need to click the Get Started button in the right-hand panel, which will open the Select or Create XBRL Outline Section wizard to associate this table with a specific XBRL outline section.
2. In the Select or Create XBRL Outline Section window, click on the Balance Sheet section, then click Add Subsection.
3. In the next step, name the Subsection Heading (Parenthetical) and click Next.
4. Select the appropriate Reference Taxonomy section, and click Next.
5. Click Next again to leave the default Heading Abstract from the previously selected Taxonomy section.
6. If you need to dimensionalize your tagging (Axis/Members), click the green checkmark on the table tag that says "us-gaap StatementTable" and click Finish.
You may now begin to tag the values in this parenthetical table.
Tagging Phantom Facts
This section defines phantom facts and demonstrates creating, tagging, and best practices for phantom facts.
A phantom fact is required when a value cannot be tagged in the primary document. For example, in a 10Q document, Note 4—Goodwill and Intangible Assets might state the following:
"As of December 31, 2010 and September 30, 2011, the goodwill related to our equity investments, included above, was approximately $27.4 million."
Although the figure 27.4 million can only be tagged with one date, a unique XBRL fact is required for each date. A phantom fact serves as the second XBRL fact for the same figure.
Creating a Phantom Fact
The non-printing section method of tagging phantom facts is quick to set up, and it places the phantom facts where they are easy to see and update.
Adding a Non-Printing Section
In the document outline, select the section that contains the value that cannot be fully tagged in the primary document, and then click the Add After toolbar button.
Name the new section similarly to the section it’s based on.
Right-click the new section, and choose Section Properties.
On the Advanced Options tab, select the Set section as non-printing check box.
Read the notice that appears saying that the section will be hidden, and no longer appear in PDF, Viewer, DOCX, or EDGAR. Click OK on the notice, and then click OK in the Section Properties dialog box.
In the outline, a non-printing section shows italic text in a lighter gray than other sections. When you display the non-printing section, it is indicated as such by a band across the top and bottom of the section.
Creating and Tagging the Phantom Fact
Turn on XBRL. In the section that contains the text in which a value is associated with multiple dates, complete the XBRL tagging for one of the required facts. In the following image, the figure is tagged for the June 30 date. The remainder of these steps refer to this section as the primary section.
In the non-printing section, insert a new table with two columns.
Type the phantom value into the right-hand column, in this case 27.4.
In the primary section, select the goodwill figure and click the Copy XBRL toolbar button in the Detail Tagging window.
In the non-printing section, select the phantom value and click the Paste XBRL toolbar button in the Detail Tagging window.
A drop-down list of paste options appears, where you can select the attributes of the XBRL data to paste. The drop-down also describes the data that exists on the clipboard and the allowable destinations where you can paste the data.
Clear the Dates / Date Ranges check box, and then click Paste.The data is pasted and the Detail Tagging window reflects the changes, with the Dates/Date Ranges section remaining untagged.
Tag the fact with the correct date (in this case I2014Q4). Click Apply.
Share your document and XBRL changes.
NOTE: You can copy only one text link at a time. You can paste the copied data to one or more other text links, or to one or more table cells.
