Incorrect Sign On Some Numeric Facts #15

Open JeffFerguson opened 6 years ago

JeffFerguson commented 6 years ago

From a user email:

I still can't seem to get the correct value for some facts.

For example: (the interactive report is here: https://www.sec.gov/cgi-bin/viewer?action=view&cik=845877&accession_number=0000845877-17-000155&xbrl_type=v#)

CashFlow (CONSOLIDATED STATEMENTS OF CASH FLOWS) fact 'us-gaap_PaymentsToAcquireLoansHeldForInvestment', the raw value in .xml file is 1047001 but I expect -1047001.

Similarly, for 'us-gaap_RepaymentsOfDebt' I expect -3416300 but actual is 3416300.

Here is one more example:

I am trying to retrieve NetIncomeLossAttributableToNoncontrollingInterest NoncontrollingInterestMember value from Q1 2017 data ([SEC link to data](https://www.sec.gov/cgi-bin/viewer?action=view&cik=845877&accession_number=0000845877-17-000092&xbrl_type=v#

equitystatement_netincomelossattributabletononcontrollinginterest

))

The fact xml from agm_20170331.xml is below:

15000 The absolute value is 15000, but in the "CONSOLIDATED STATEMENTS OF EQUITY Statement" at SEC site showing the value as -15000 (negative 15). The presentation link (agm-20170331_pre.xml) is available and it has the reference to the above fact. However, there are no facts in Calculation link base (agm-20170331_cal.xml). My guess is perhaps there are few more xml files - probably from the default gaap - that need to be analyzed to determine the correct sign. I hope this helps. equitystatement_netincomelossattributabletononcontrollinginterest

Thank you for the additional information! Do you, by chance, have URLs to the XBRL document instances?

My guess is that it has to do with Gepsio possibly not respecting the decimals=-3 sign in the <us-gaap:NetIncomeLossAttributableToNoncontrollingInterest contextRef="FD2017Q1YTD_us-gaap_StatementEquityComponentsAxis_us-gaap_NoncontrollingInterestMember" decimals="-3" id="Fact-080C7834C860474640CE01C86E8BFB62" unitRef="usd"> element, but I would like to check to be sure.

Here is the link to xbrl instance: https://www.sec.gov/Archives/edgar/data/845877/000084587717000092/agm-20170331.xml

So far, I did not see any issues with decimals. All decimal values have expected zeros.
