DQC Rule Common Mistakes

Axis with Inappropriate Members• Cause consumers challenges with consistency and comparability• Highest Firing Errors

◦ Statement Equity Components [Axis]

◦ Legal Entity [Axis]

◦ Consolidation Items [Axis]

Axis with Inappropriate Members

Statement Equity Components [Axis]• Intended to disaggregate equity in to applicable components• Primary usage on the Statement of Shareholders' Equity• Common mistakes

▪ Class of stock usage error

▪ Total equity members error

Axis with Inappropriate MembersStatement Equity Components [Axis] - common mistakes• Class of stock usage error - Class A, B, C etc. on Equity Components Axis

• Correct usage: Separate axis for detailed class of stock components

Axis with Inappropriate Members

Statement Equity Components [Axis] - common mistakes• Total equity members error• Correct usage: "Parent" on sub-total before NCI, no member at all on grand

total

ASU Adoption and Implementation

• Debt issuance costs (ASU 2015-03)• Deferred tax asset and liability classification (ASU 2015-17)• Net Asset Value practical expedient (ASU 2015-07)

ASU Adoption and Implementation

Debt Issuance Costs (ASU 2015-03)• ASU requires debt issuance costs to be presented as direct deduction from

carrying amount of related liability• Consistent approach with debt discounts• Elements were modified and new structure added to 2016 Taxonomy

Debt Issuance Costs (ASU 2015-03)

Data review of debt issuance elements• Almost 1,000 elements related to "debt issuance" used in 2016 filings• Less than 30 elements in the standard taxonomy reference debt issuance• Identified other issues with Amortization and Carrying Value tagging

Common Mistake: Incorrect Fact Values• Making the calculation relationship work

▪ Defining backwards would cause negative fact value for discount and issuance costs

ASU Adoption and Implementation

Deferred tax asset and liability classification (ASU 2015-17)• ASU updates classification of deferred taxes to noncurrent• Previously allocated to current and noncurrent• Common adoption mistakes

ASU Adoption and Implementation

Net Asset Value practical expedient (ASU 2015-07)• Investments at NAV no longer are assigned to FV hierarchy level• Previously, NAV was Level 2 and Level 3• Different tagging approaches used causing challenges and review

Net Asset value Practical Expedient (ASU 2015-07)

• Same information, regardless of presentation style

Net Asset value Practical Expedient (ASU 2015-07)

Modeling analysis:• Current taxonomy approach is line item modeling• Data identifies different interpretation of modeling

▪ Various Axes with extended Members

▪ Extended elements

• Confusion in modeling results in open initiative for FASB Taxonomy updates

Taxonomy Updates

• Taxonomy has revisions each year• Not all revisions result in "auto" updating when migrating• Requires additional analysis and review of changes to incorporate updates• Results in inconsistent modeling for comparability or unnecessary extensions

▪ Accumulated Other Comprehensive Income modeling

▪ Axis/Member mismatch impacting future modeling

Taxonomy Updates

Accumulated Other Comprehensive Income Modeling• New Members added to 2015 Taxonomy for AOCI Members

▪ Added AOCI Members for Noncontrolling Interest

▪ Added AOCI Members for Including Noncontrolling Interest

• Prior Members Attributable to Parent were not deprecated• If disclosure was Including NCI or specific to NCI, Members needed to be

manually updated

Accumulated Other Comprehensive Income Modeling

Label and definition update, notdeprecated.

Use on "IncludingNoncontrolling Interest"disclosure would be incorrect.

Taxonomy Updates

Axis/Member mismatch - Parent [Member]• Recap from prior slide:

▪ Legal Entity [Axis] - Parent Company [Member]

▪ Statement Equity Components [Axis] - Parent [Member]

• Anticipation of future taxonomy updates:◦ 2017 Taxonomy - Parent Company [Member] moving to new Axis

◦ Required action less obvious if Parent [Member] still used under Legal Entity [Axis]

• Taxonomy Implementation Guide▪ Dimensional Modeling for Disclosures of Consolidated and Nonconsolidated Entities

• Are you concerned about your axis usage or the number ofextended axis?

• Have you wondered if your XBRL data is current with the2016 Taxonomy?

• Are you concerned about getting a Dear CFO letter inregards to your XBRL?
