(i) Investor assurance program, page F-14

2.       We note your response to comment 10 and that service fees collected
from "all the loans"
         are utilized to compensate investors under the investor assurance
program as well as
         the other guarantee liabilities assumed in the Niwodai transaction.
Please revise to clarify
         the underlying population of "all the loans" including if you receive
service fees related to
         the underlying loans for other guarantee liabilities acquired in the
Niwodai Finance
         acquisition.
3.       We note your response to comment 11 and that with the overall
improvement of the
         Company's credit management capability, the net expected accumulative
loss rate has
         declined for the periods presented. We also note from your Critical
Accounting Policies,
         Judgments and Estimates on page 101 for your Investor Assurance
Program, that
         expected collection rates of defaulted loans is a significant
unobservable input in the
         determination of the net expected accumulative loss rate and the
estimate of the allowance
         for uncollectible accounts as stated in your response to comment 15.
Please revise to
         disclose estimated recoveries used in the determination of the net
expected accumulated
         loss rates on the outstanding loans for each of the periods presented
as discussed in your
         response to comment 12, including how these amounts are reflected in
the allowance for
         uncollectible accounts receivables and contract assets.
(k) Restricted Cash, page F-14

4.       We note your response to comment 8. Please address the following:
           You state that contributions from both new loans and old loans are
deposited to the
           designated restricted cash accounts for the investor assurance
program. Please
           disaggregate the contributions from borrowers between loans
facilitated by you and
           those related to the Niwodai Finance acquisition. Additionally,
explain why no asset
           was recognized for contributions due to you in connection with the
Niwodai Finance
           acquisition;
             You state that contribution from borrowers has no direct
relationship with the
             collection of assets from the investor assurance program. You also
state on page F-14,
             that under the investor assurance program, you set aside a certain
percentage of service
             fees into designated restricted cash accounts to be used to cover
on a portfolio basis
             the principal and interest of defaulted loans, payable on a
first-loss basis up to the
             balance of the investor assurance program. Disclose the nature of
the service fees set a

             side into designated restricted cash accounts;
             Tell us why contributions from borrowers for service fees
collected in the name of
             "Post origination service fees" and "Post-loan management fees"
would be designated
             as restricted cash used to satisfy your investor assurance
liabilities; and
             You state that the collection of assets from the investor
assurance program represents
             any service fees, regardless of their name, collected from
borrowers that are applied
             against the balance of the assets from the investor assurance
program. You also state
             on page F-16, that the asset from investor assurance program is
recognized initially at
             loan inception corresponding to the stand-ready liability measured
at fair value at
             inception, representing the fair value of service fees receivable
from the underlying
             loans that are expected to be used for the estimated payout of the
corresponding
             guarantee liabilities. Tell us your basis for applying service
fees other than the
             guarantee service to the asset from investor assurance program.
Refer to ASC 460-10-
             30-2.

7.       We note your response to comment 15 and that the allowance for
uncollectible accounts
         for contract assets is based on estimates, historical experience and
other factors
         surrounding the credit risk of specific customers which is essentially
the net expected
         accumulative loss rates used in determining the fair value of
guarantee liabilities under
         each product type. We also note your disclosure that the concept of
aging is not
         applicable to contract assets given the nature of these assets. Please
address the following;
           Tell us why write-off activity for contract assets and accounts
receivable for the six
             months ending June 30, 2018 is not reflective of net payout
activity in the liabilities
             from investor assurance programs for the same period since the
underlying payments
             for both service fees and monthly repayment of principal and
interest are due and
             made together;
           Tell us why the allowance for uncollectible accounts and contract
assets of RMB

for current loan

accumulative loss rate on
          outstanding loans of 10.6% used in determining the fair value of
guarantee liability for
          the investor assurance program as of June 30, 2018 disclosed on page
F-55;
          Tell us why the allowance for uncollectible accounts and contract
assets of RMB
          157,826 and 38% of total contract assets and accounts receivable for
offline and non-
          standard loan products of RMB 414,709 is greater than the net
expected accumulative
          loss rate on outstanding loans of 20.1% used in determining the fair
value of guarantee
          liability for the investor assurance program as of June 30, 2018
disclosed on page F-
          55; and
          Tell us why write-offs for current loan products during the period
ending June 30,
          2018 were only RMB 8,387 considering contract assets for current loan
products of
          RMB 352,980 at December 31, 2017, the net expected accumulative loss
rate of 11%
          and weighted average contractual term of 8 months as disclosed on
page F-55.
8.    Please revise the asset activity table to disclose the movement of
accounts receivable and
      contract assets separately for the periods presented. Similar disclosures
should be made
      for the movement in uncollectible accounts receivable and contract
assets.
9.    We note the disclosure that accounts receivable and contract assets are
identified as
      uncollectible if the amount remains outstanding for 90 calendar days past
due after the
      maturity of the underlying loan contract term and no other factors
evidences the
      possibility of collecting delinquent amounts. Please clarify if "the
maturity of the
      underlying loan contract term" as it relates to repayments, is the same
as the definition
      used in determining the "M3+ Delinquency Rate By Vintage" which appears
to be the
      total amount of principal for all loans in a vintage for which any
repayment was more than
      90 days past due as of a particular date.
