Forms 10-D and ABS-EE of BANK 2019-BNK16, Wells Fargo Commercial Mortgage Trust
2017-C38 and Wells Fargo Commercial Mortgage Trust 2017-C39

   1. We have reviewed your responses to prior comments 2, 5 and 7 and it
continues to
      remain unclear how the servicers were permitted to advance payments under
the related
      transaction agreement. While you contend that payments were still
considered to be due
      during the period of the forbearance, we note that the obligor was not
expected to make

         principal and interest payments during the forbearance period.
Instead, consistent with
         the reporting of loan as    current    during the period of
forbearance, those payments were
         not, in effect, due until after the end of the forbearance period. For
that reason, the
         servicer, in continuing to make advances while the loan was in
forbearance, was not in
         compliance with Item 1122(d)(2)(iii) of Regulation AB relating to
advances for funds for
         these transactions and should identify such material instances of
noncompliance in its
         assessment to be filed with your Form 10-K for the previous fiscal
year.

      2. We also note your responses to prior comments 1, 3 and 6 indicating
that industry best
         practices allow reporting of forbearances within two reporting cycles
and your response
         to prior comment 8 noting that the servicer does not believe that
there have been material
         instances of noncompliance to report for the previous fiscal year.
Please be advised that
         Item 1122 of Regulation AB requires, among other things, that the
servicer assess
         whether reports, which includes the filed asset-level data, are
maintained in accordance
         with the transaction agreements and applicable Commission
requirements. Item 1122
         requirements do not involve an assessment against industry best
practices. In addition, as
         we have noted in our comments above, we continue to have concerns that
P&I advances
         were not made as specified in the transaction agreements, as required
to be assessed
         under Item 1122(d)(2)(iii). Item 1122(d)(2)(iii) does not involve a
consideration of
         industry best practices. If the delays in reporting resulted in
material delays in reporting
         the forbearance across several transactions in a servicing platform,
we believe that the
         servicer should report these delays as material instances of
noncompliance with
         applicable servicing criteria in its assessments to be filed with your
Form 10-K for the
         previous fiscal year.

       Please contact Michelle Stasny at 202-551-3674 or me at 202-551-3850
with any other
questions.


                                                               Sincerely,
