INFORMATION).

Based  on the  standards  set  forth  in  Item  1115(b)  of  Regulation  AB,  no

ITEM 1117 OF REGULATION AB: LEGAL PROCEEDINGS.

There are no material pending legal or other proceedings  involving the mortgage
loans or Residential Funding Company,  LLC ("Residential  Funding"),  as sponsor
and master servicer, Residential Accredit Loans, Inc., as depositor, RALI Series
2006-QS16   Trust,   as  the  issuing   entity,   Homecomings   Financial,   LLC
("Homecomings")  and GMAC Mortgage,  LLC ("GMACM"),  as  subservicers,  or other
parties  described in Item 1117 of  Regulation AB that,  individually  or in the
aggregate,  would have a material  adverse impact on investors in the securities
(the "Securities") to which this report relates.


<PAGE>

Residential  Funding,  Homecomings  and GMACM are  currently  parties to various
legal  proceedings  arising  from time to time in the  ordinary  course of their
businesses,  some of which  purport to be class  actions.  Based on  information
currently available,  it is the opinion of Residential Funding,  Homecomings and
GMACM that the  eventual  outcome of any  currently  pending  legal  proceeding,
individually  or in the  aggregate,  will not have a material  adverse effect on
their ability to perform their obligations in relation to the mortgage loans. No
assurance,  however,  can be  given  that  the  final  outcome  of  these  legal
proceedings, if unfavorable,  either individually or in the aggregate, would not
have a material adverse impact on Residential Funding, Homecomings or GMACM. Any
such  unfavorable  outcome  could  adversely  affect the ability of  Residential
Funding,  Homecomings  or GMACM to perform its servicing  duties with respect to
the  mortgage  loans and  potentially  lead to the  replacement  of  Residential
Funding, Homecomings or GMACM with a successor servicer.

ITEM 1119 OF REGULATION AB:  AFFILIATIONS AND CERTAIN RELATIONSHIPS AND
RELATED TRANSACTIONS.

Information  contemplated  by Item 1119 of  Regulation  AB has been omitted from
this report in reliance on the Instruction to Item 1119.

ITEM 1122 OF REGULATION AB: COMPLIANCE WITH APPLICABLE SERVICING CRITERIA.

Each of  Residential  Funding  Company,  LLC, GMAC  Mortgage,  LLC,  Homecomings
Financial,  LLC, Greenpoint Mortgage Funding,  Inc., Assurant Inc.,  LandAmerica
Tax and Flood Services,  Inc., HSBC Mortgage  Corporation  (USA), First American
Real Estate Solutions of Texas, L.P.,  National City Mortgage Co., Regulus Group
LLC,  SunTrust   Mortgage,   Inc.,   SunTrust  Bank,  Inc.,   Wachovia  Mortgage
Corporation,  ZC Sterling  Insurance Agency,  Inc.,  Deutsche Bank Trust Company
Americas  and  Wells  Fargo  Bank,  National  Association  (each,  a  "Servicing
Participant") has been identified by the registrant as a party  participating in
the  servicing  function  with  respect to the pool  assets  held by the Issuing
Entity.  Each Servicing  Participant  has completed a report on an assessment of
compliance with the servicing criteria applicable to such Servicing  Participant
(each,  a "Report on  Assessment")  as of  December  31, 2006 and for the period
covered by this Form 10-K,  which Reports on Assessment are attached as exhibits
to this Form 10-K.  In  addition,  each  Servicing  Participant  has provided an
attestation report (each, an "Attestation  Report") by a registered  independent
public  accounting  firm  regarding  its  related  Report  on  Assessment.  Each
Attestation Report is attached as an exhibit to this Form 10-K.

A Servicing  Participant may engage one or more vendors to perform  specific and
limited,  or scripted  activities  that  address all or a portion of one or more
servicing criteria applicable to such Servicing Participant. In general in these
cases,  the Servicing  Participant  has  instituted  policies and  procedures to
monitor whether such vendors'  activities  comply in all material  respects with
such  servicing  criteria,  and may elect to take  responsibility  for assessing
compliance with the servicing criteria applicable to such vendors' activities in
such  Servicing   Participant's  Report  on  Assessment.   Where  the  Servicing
Participant  has not  instituted  such  policies  and  procedures,  or where the
Servicing  Participant  does  not  otherwise  elect to take  responsibility  for
assessing its vendors'  activities,  the vendor is itself treated as a Servicing
Participant  and is required to provide its own Report on Assessment and related
Attestation Report.

Except as disclosed below, no Report on Assessment or related Attestation Report
has identified  (i) any material  instance of  noncompliance  with the servicing
criteria  identified  in such Report on  Assessment as applicable to the related
Servicing  Participant  or  (ii)  any  material  deficiency  in  such  Servicing
Participant's policies and procedures to monitor vendor compliance.

Exceptions:

Residential  Funding  Company,   LLC:  The  Report  on  Assessment  prepared  by
Residential  Funding  Company,  LLC  and the  related  Attestation  Report  have
identified material noncompliance with one servicing criterion applicable to it.
Specifically,   with  regard  to  servicing  criterion  1122(d)(3)(i)(B)  (which
contemplates  that  reports  to  investors  provide  information  calculated  in
accordance with the terms specified in the transaction agreements),  information
required  by the  transaction  agreements  was  excluded  from,  or  incorrectly
reported in, certain of the investor  reports.  The registrant  does not believe
these  reporting  errors had any material  impacts or effects on  investors  and
corrective action was completed to address ongoing compliance.


<PAGE>

GreenPoint  Mortgage  Funding,  Inc.:  The  Report  on  Assessment  prepared  by
GreenPoint  Mortgage Funding,  Inc. ("GMF") and the related  Attestation  Report
have  identified  material  instances  of  noncompliance  with  three  servicing
criteria applicable to it. Specifically -

   o  With regard to servicing criterion 1122(d)(1)(i),  which contemplates that
      policies and procedures are instituted to monitor any performance or other
      triggers  and  events  of  default  in  accordance  with  the  transaction
      agreements, GMF had not instituted such policies and procedures.

   o  With regard to  servicing  criterion  1122(d)(2)(iv),  which  contemplates
      that, for each  transaction,  the related  custodial or other accounts are
      separately maintained as set forth in the transaction agreements,  GMF did
      not establish  separate  accounts for each transaction as set forth in the
      applicable transaction agreements, which allowed funds to be commingled in
      various custodial accounts.

   o  With regard to servicing criterion 1122(d)(3)(ii), which contemplates that
      amounts due to investors are allocated and remitted in accordance with the
      terms of the transaction agreements,  amounts due to investors were not so
      remitted.  GMF  indicates  that, in certain  situations  where it received
      mortgage  insurance  proceeds  prior  to the  liquidation  of the  related
      properties,  the mortgage insurance proceeds were not remitted at the time
      of the  next  regularly  scheduled  remittance  date  as  required  by the
      transaction  agreements,  but instead  remained  in the related  custodial
      account and were  remitted at the time the REO  liquidation  proceeds were
      remitted to the master servicer.

GMF indicates in Appendix B to its Report on Assessment  that these instances of
noncompliance have been or will be addressed,  either by appropriate  corrective
action or, in the case of its remittance practices,  by modifying the applicable
transaction  agreements to conform to its practices.  We have not  independently
verified the  accuracy of GMF's  assertions  or the adequacy of its  remediation
efforts.


First  American Real Estate  Solutions of Texas,  L.P.: The Report on Assessment
prepared  by First  American  Real  Estate  Solutions  of  Texas,  L.P.  ("First
American") and the related Attestation Report have identified material instances
of noncompliance with one servicing  criterion  applicable to it.  Specifically,
with regard to servicing criterion  1122(d)(2)(vii)(B),  which contemplates that
reconciliations are prepared on a monthly basis for all asset-backed  securities
related bank  accounts,  First  American  did not prepare  such  reconciliations
within 30  calendar  days after the bank  statement  cut-off  date or such other
number of days specified in the related transaction agreements.

National City  Mortgage Co: The Report on  Assessment  prepared by National City
Mortgage Co. ("NCM") and the related Attestation Report have identified material
instances  of  noncompliance  with  one  servicing  criteria  applicable  to it.
Specifically,   with  regard  to  servicing  criterion  1122(d)(3)(i)(A)  (which
contemplates   that  reports  to  investors  are  prepared  in  accordance  with
timeframes and other terms set forth in the transaction  agreements),  instances
were noted (NCM indicates 29 possible  instances) in which NCM failed to provide
the  master  servicer  with  delinquency/default  loan data  reports  within the
timeframes or otherwise as set forth in the transaction agreements.


<PAGE>

SunTrust Mortgage, Inc.: The Report on Assessment prepared by SunTrust Mortgage,
Inc.  ("SMI")  and the  related  Attestation  Report  have  identified  material
instances of  noncompliance  with three  servicing  criteria  applicable  to it.
Specifically, for the period from January 1, 2006 through December 31, 2006 -

   o  With regard to servicing criterion 1122(d)(1)(i),  which contemplates that
      policies and procedures are instituted to monitor any performance or other
      triggers  and  events  of  default  in  accordance  with  the  transaction
      agreements, SMI had not instituted such policies and procedures.

   o  With regard to servicing criterion 1122(d)(2)(i),  which contemplates that
      payments on pool assets are  administered  in accordance with the terms of
      the transaction  agreements,  SMI did not deposit payments on the mortgage
      loans into the  appropriate  custodial  bank  accounts  and  related  bank
      clearing accounts within two business days of receipt or such other number
      of days specified in the transaction agreements.

   o  With regard to  servicing  criterion  1122(d)(2)(iv),  which  contemplates
      that, for each  transaction,  the related  custodial or other accounts are
      separately maintained as set forth in the transaction agreements,  SMI did
      not separately maintain such accounts for each transaction as set forth in
      the applicable transaction agreements.

Platform-Level Reports:

Regulations of the Securities and Exchange  Commission  (the "SEC") require that
each  Servicing  Participant  complete a Report on  Assessment  at a  "platform"
level,  meaning that the transactions covered by the Report on Assessment should
include  all  asset-backed  securities  transactions  involving  such  Servicing
Participant  that are backed by the same asset type.  More recent  guidance from
the SEC staff identifies additional parameters which a Servicing Participant may
apply to define  and  further  limit its  platform.  For  example,  a  Servicing
Participant  may define its  platform  to include  only  transactions  that were
completed  on or after  January  1, 2006 and that were  registered  with the SEC
pursuant  to  the  Securities  Act  of  1933.  Each  Servicing   Participant  is
responsible  for defining its own platform,  and each  platform  will  naturally
differ based on various factors,  including the Servicing Participant's business
model and the transactions in which it is involved.

Wachovia  Mortgage  Corporation's  ("WMC")  Report  on  Assessment  defines  its
platform to include the asset-backed securities transactions for which it serves
as a servicer  involving first lien mortgage  loans.  Exhibit A to its Report on
Assessment  identifies  the  individual  asset-backed  transactions  defined  by
management as constituting  its platform,  but does not include the asset-backed
transaction to which this Form 10-K relates.

<PAGE>

Neither  WMC's  Report on  Assessment  nor its  related  Attestation  Report has
identified  (i) any  material  instance  of  noncompliance  with  the  servicing
criteria  identified  in such Report on  Assessment as applicable to WMC or (ii)
any material  deficiency  in WMC's  policies and  procedures  to monitor  vendor
compliance.  WMC has  advised us that the  mortgage  loans  held by the  Issuing
Entity that WMC services are serviced in  accordance  with the same policies and
procedures,  and to the same  standards,  as it  applies to the  mortgage  loans
included in its platform.

Except as discussed above, based on our understanding of their platforms and the
guidance that is available at this time, we believe that the parameters by which
the Servicing  Participants  have defined their platforms should be permissible.
However,  because  the  SEC's  regulations  are  new and  the  guidance  that is
available at this time is subject to clarification  or change,  we cannot assure
you that the SEC and its staff will necessarily agree.

ITEM 1123 OF REGULATION AB: SERVICER COMPLIANCE STATEMENT.

Each of  Residential  Funding  Company,  LLC, GMAC  Mortgage,  LLC,  Homecomings
Financial,  LLC and National  City Mortgage Co.  (each,  a "Servicer")  has been
identified by the  registrant as a servicer with respect to the pool assets held
by the Issuing Entity. Each Servicer has provided a statement of compliance with
its  obligations  under  servicing  agreement  applicable  to such  Servicer  (a
"Compliance  Statement")  for the period covered by this Form 10-K, in each case
signed  by an  authorized  officer  of the  related  servicer.  Each  Compliance
Statement is attached as an exhibit to this Form 10-K.

Except as disclosed  below, no Compliance  Statement has identified any instance
where the  related  Servicer  has failed to fulfill  its  obligations  under the
applicable servicing agreement in any material respect.

Exceptions:

SunTrust Mortgage,  Inc. The Compliance Statement prepared by SunTrust Mortgage,
Inc. ("SMI")  indicates that, as of January 1, 2006, SMI did not have procedures
in place  to  monitor  compliance  with  provisions  of  applicable  transaction
agreements  governing  transactions  subject  to  Regulation  AB,  including  in
particular  provisions  relating to or affecting the servicing criteria outlined
in Item 1122 of Regulation AB.

SMI indicates in its Compliance Statement that specific measures were undertaken
and completed to address the absence of such procedures, as more fully described
in its Compliance Statement.  We have not independently verified the accuracy of
SMI's assertions or the adequacy of its remediation efforts.
