3.   The  registrant's  leased  equipment is  primarily  leased under triple net
     leases  under which the lessee  bears all of the  maintenance  costs.  As a
     result, the actual equipment maintenance charges incurred by the registrant
     in  2008  and  2007  have  not  been  significant.  As a  consequence,  the
     registrant  has not  recognized  the  expense  until  it was  fixed  and/or
     determinable,  which is generally  upon receipt of the related  third party
     invoice.  The full year  maintenance  expenses  have not  exceeded  $250 in
     either 2008 or 2007.

Leases, page 27

4.   For Notes  Receivable,  Net, the registrant's  footnote  disclosure will be
     revised to include  quantification  of the  amount of notes  receivable  in
     non-accrual status as of the end of each period presented, as indicated pro
     forma below (as appropriate for each period):

     "The Company has various notes  receivable from borrowers who have financed
     the  purchase  of  equipment  through the  Company.  The terms of the notes
     receivable  are 24 to 120 months and bear  interest at rates  ranging  from
     ___% to ___%. The notes are secured by the equipment financed.

     At December 31, 200y, the Company recorded an impairment provision totaling
     $____  related  to ___  notes  receivable,  ___ of  which  remained  in the
     portfolio as of December 31, 200y.

     The amount of notes receivable,  net, in non-accrual  status as at December
     31,  200z  and  200y  totaled  $________  and  $__________.  There  were no
     additional impaired notes at December 31, 200x.

     For direct financing leases,  the registrant's  footnote will be revised to
     include tabular  disclosure of such leases placed in non-accrual  status as
     of the end of each  period  presented,  as  indicated  pro forma  below (as
     appropriate for each period):

5.   This will confirm that a new cost basis is assigned by the  registrant  for
     any assets for which an  impairment  loss is recorded  and that  impairment
     losses are not reversed, in accordance with SFAS 144.

Note 8,  Non-Recourse Debt, page 29, and Note 9, Borrowing Facilities, page 30

6.   The  non-recourse  note payable  referred to in Note 8 of the  registrant's
     Form 10-K does not contain any  material  financial  covenant.  The note is
     secured by a lien granted by the registrant to the  non-recourse  lender on
     (and only on) the  discounted  lease  transaction.  The lender has recourse
     only to the  following  collateral:  the  specific  leased  equipment;  the
     related lease chattel  paper;  the lease  receivables;  and proceeds of the
     foregoing items. The non-recourse  obligation is payable solely out of this
     specific  security  and  the  registrant  does  not  guarantee  (nor is the
     registrant  otherwise   contractually   responsible  for)  the  payment  of
     non-recourse  note as a general  obligation or liability of the registrant.
     Although  the  registrant  does not have any direct  general  liability  in
     connection with the non-recourse note apart from the security granted,  the
     registrant is directly and  generally  liable and  responsible  for certain
     representations,  warranties,  and  covenants  made to the lender,  such as
     warranties as to genuineness of the transaction parties' signatures,  as to
     the  genuineness of the lease chattel paper or the  transaction as a whole,
     or as to the  registrant's  good  title  to or  perfected  interest  in the
     secured  collateral,  as well as similar  representations,  warranties  and
     covenants typically provided by non-recourse borrowers and customary in the
     equipment  finance  industry,  and are viewed by the such industry as being
     consistent with a non-recourse discount financing obligation.  Accordingly,
     as there are no financial  covenants or ratios imposed on the registrant in
     connection with this non-recourse obligation, the registrant has determined




Mr. Rufus Decker
August 3, 2009
Page 4


     that there are no material  covenants with respect to the non-recourse note
     that warrant footnote disclosure.

     With  respect  to the  Note  9  regarding  the  borrowing  facilities,  the
     registrant proposes to add the following disclosure, as appropriate, to its
     future  reports  under  "Management's  Discussion  and  Analysis  - Capital
     Resources and Liquidity," and will consider expanded footnote disclosure to
     address these issues, again as appropriate:

     "Revolving credit facility

     The  Company  participates  with AFS and  certain  of its  affiliates  in a
     revolving  credit facility (the "Credit  Facility")  comprised of a working
     capital  facility  to  AFS,  an  acquisition   facility  (the  "Acquisition
     Facility") and a warehouse facility (the "Warehouse  Facility") to AFS, the
     Company and affiliates,  and a venture facility  available to an affiliate,
     with a syndicate of financial institutions.

     Compliance with covenants

     The Credit Facility includes certain financial and non-financial  covenants
     applicable to each borrower,  including the Company. Such covenants include
     covenants  typically  found in credit  facilities of the size and nature of
     the Credit Facility,  such as accuracy of  representations,  good standing,
     absence of liens and material  litigation,  etc. The Company and affiliates
     were in  compliance  with all  covenants  under the Credit  Facility  as of
     December 31, 200x. The Company considers certain financial  covenants to be
     material to its ongoing use of the Credit  Facility and these covenants are
     described below.

     Material financial covenants

     Under the Credit  Facility,  the Company is required to maintain a specific
     tangible  net  worth,  to comply  with a  leverage  ratio  and an  interest
     coverage  ratio,  and to comply  with other terms  expressed  in the Credit
     Facility,  including  limitation on the  incurrence of additional  debt and
     guaranties,  defaults, and delinquencies.  The material financial covenants
     are summarized as follows:

           Minimum Tangible Net Worth:  $________
           Leverage Ratio (leverage to Tangible Net Worth):  ___%
           Collateral Value:  Collateral value under the Warehouse Facility must
           exceed outstanding borrowings under that facility.
           EBITDA to Interest Ratio:  Not less than [2 to 1] for the four fiscal
           quarters just ended.

     "EBITDA" is defined under the Credit  Facility as, for the relevant  period
     of time (1) gross revenues  (including  but not limited to interest  income
     and all rents from leases) for such period  minus (2) expenses  deducted in




Mr. Rufus Decker
August 3, 2009
Page 5

     determining  net income for such period plus (3) to the extent  deducted in
     determining  net income for such period (a)  provision for income taxes and
     (b) interest expense, and (c) depreciation, amortization and other non-cash
     charges.  Extraordinary  items and gains or losses on (and  proceeds  from)
     sales or  dispositions of assets outside of the ordinary course of business
     are excluded in the calculation of EBITDA.  "Tangible Net Worth" is defined
     as,  as of the date of  determination,  (i) the net  worth of the  Company,
     after deducting therefrom (without  duplication of deductions) the net book
     amount of all assets of the Company, after deducting any reserves and other
     amounts for assets which would be treated as intangibles  under GAAP,  (U.S
     Generally   Accepted   Accounting   Principles)  and  after  certain  other
     adjustments permitted under the agreements.

     The  financial  covenants  referred to above are  applicable to the Company
     only to the extent that the Company has  borrowings  outstanding  under the
     Credit  Facility.  For the period ended  December 31, 200x,  the  Company's
     Tangible Net Worth  requirement under the Credit Facility was [$15,000,000]
     the permitted  maximum leverage ratio was [1.25],  and the required minimum
     interest coverage ratio  (EBITDA/interest  expense) was [2.00]. The Company
     was in  compliance  with  each  these  financial  covenants  with a minimum
     Tangible Net Worth, leverage ratio and (EBITDA) interest coverage ratio, as
     calculated per the Credit Facility agreement of $_________, 0.xx, and x.xx,
     respectively,  for the same period ended  December 31, 200x. As such, as of
     December 31, 200x, the Company and its affiliates  were in compliance  with
     all such material financial covenants.

     Reconciliation to GAAP of EBITDA

     For purposes of compliance with the Credit Facility covenants,  the Company
     uses a financial  calculation  of EBITDA,  as defined  therein,  which is a
     non-GAAP  financial  performance  measure.  The EBITDA is  utilized  by the
     Company to calculate its debt covenant ratios

     The  following is a  reconciliation  of EBITDA to net income for the period
     ended December 31, 200x ($'s in thousands):

Net income (loss) - GAAP basis                                      $    (x,xxx)
Interest expense                                                          x,xxx
Depreciation and amortization                                            xx,xxx
Amortization of initial direct costs                                        xxx
Reversal of provision for doubtful accounts                                  (x)
Provision for losses on notes receivable                                    xxx
Change in fair value of interest rate swap contracts                      x,xxx
Payments received on direct finance leases                                x,xxx
Payments received on notes receivables                                    x,xxx
Amortization of unearned income on direct finance leases                   (xxx)
Amortization of unearned income on notes receivables                       (xxx)
EBITDA                                                              $    xx,xxx]

     Events of default, cross-defaults, recourse and security

     The terms of the Credit Facility  include standard events of default by the
     Company which,  if not cured within  applicable  grace periods,  could give
     lenders  remedies  against the Company,  including the  acceleration of all
     outstanding  borrowings  and a demand  for  repayment  in  advance of their
     stated  maturity.  If a breach of any material term of the Credit  Facility
     should occur, the lenders may, at their option,  increase  borrowing rates,
     accelerate the obligations in advance of their stated maturities, terminate
     the facility, and exercise rights of collection available to them under the
     express  terms of the  facility,  or by  operation of law. The lenders also
     retain the discretion to waive a violation of any covenant at the Company's
     request.

     The Company is  currently  in  compliance  with its  obligations  under the
     Credit Facility.  In the event of a technical default (e.g., the failure to
     timely  file  a  required  report,  or a  one-time  breach  of a  financial
     covenant), the Company believes it has ample time to request and be granted
     a waiver by the  lenders,  or,  alternatively,  cure the default  under the
     existing  provisions  of its  debt  agreements,  including,  if  necessary,
     arranging  for  additional   capital  from  alternate  sources  to  satisfy
     outstanding obligations.

     The lending  syndicate  providing the Credit Facility has a blanket lien on
     all of the Company's  assets as collateral for any and all borrowings under
     the  Acquisition  Facility,  and on a pro-rata  basis  under the  Warehouse
     Facility.

     The Acquisition  Facility is generally recourse solely to the Company,  and
     is not  cross-defaulted  to any other  obligations of affiliated  companies
     under the Credit  Facility,  except as  described  in this  paragraph.  The
     Credit Facility is  cross-defaulted to a default in the payment of any debt
     (other than  non-recourse  debt) or any other agreement or condition beyond
     the  period of grace (not  exceeding  30 days),  the effect of which  would
     entitle the lender under such agreement to accelerate the obligations prior
     to their stated maturity in an individual or aggregate  principal amount in
     excess of [fifteen] percent ([15]%) of the Company's  consolidated Tangible
     Net Worth. Also, a bankruptcy of AFS will trigger a default for the Company
     under the Credit Facility."


Exhibit 31

7.   We note the missing references in the introductory portions of paragraphs 4
     and 5 to "internal  control over financial  reporting." The registrant made
     the correct  certification in its subsequent  quarterly report on Form 10-Q
     for the first  quarter  of 2009,  and will make  certain  that the  correct
     certifications  are filed with each of its  future  periodic  reports.  The
     staff has directed  that the  registrant  file an amended Form 10-K for the




Mr. Rufus Decker
August 3, 2009
Page 7

     year ended  December 31, 2008, to replace the current  Exhibits 31 with new
     and updated  Exhibits 31 with the corrected  references in the introductory
     paragraphs to those two items. The registrant requests that its undertaking
     to provide the corrected  certifications in all future filings be deemed to
     satisfy this comment without the need to file an amended Form 10-K.

     The registrant  would point out that,  while the  introductory  portions of
     paragraphs  4 and 5 omit the required  reference to "internal  control over
     financial  reporting," the substantive portions of those paragraphs,  items
     4(b) and 4(d), and items 5(a) and 5(b), do contain the required  references
     to internal control over financial  reporting.  The officers have therefore
     already  certified  in the Form 10-K to the  design of such  controls,  the
     disclosure  of any  material  changes to such  controls in the report,  and
     disclosure of any deficiencies or material weaknesses in such controls,  or
     fraud  by any  person  with a  significant  role  in such  control,  to the
     auditors and audit  committee.  The registrant  would further note that its
     subsequent  quarterly report on Form 10-Q includes the complete and correct
     certifications for the quarter ended March 31, 2009.

     The registrant  would therefore  assert that its responsible  officers have
     made the substantive  certifications  for the year ended December 31, 2008,
     have made updated  certifications  as of the subsequent first quarter ended
     March 31,  2009,  and will make them as of the quarter  ended June 30, 2009
     and every  subsequent  period.  The registrant  believes that the potential
     cost and delay in its current  periodic  reporting  that would  result from
     preparing and filing an amended  report for the purpose of  correcting  the
     introductory  portions of the  paragraphs  should  therefore  outweigh  any
     benefit to public  disclosure  that might be deemed  necessary  under these
     circumstances.

     As the  staff is  aware,  the  registrant  and five of its  affiliates  are
     subject to this same comment, so insistence upon an amended Form 10-K would
     mean the  registrant's  management would be required to prepare six amended
     10-Ks,  while at the  same  time  preparing  those  same  six  registrants'
     periodic  reports for the quarter  ended June 30, 2009,  adding to the cost
     and potentially delaying completion of reporting for the current period. As
     correcting  these   certifications  would  be  the  only  reason  for  such
     amendments  to the 10-Ks,  the  registrant  hereby  requests that the staff
     concur that this comment is satisfied with the registrant's  undertaking to
     make certain that the correct certifications continue to be provided in all
     subsequent periodic reports.

General

8.   The  responsive  changes  proposed with respect to future annual reports on
     Form 10-K will,  upon Staff  confirmation  of our  proposed  responses,  be
     similarly addressed in all future interim reports.

Note 11,  Subsequent Event, page 16

9.   In determining  that no adjustments  needed to be recorded  related to this
     lessee  (Chrysler),  the  Company  first took into  consideration  that the
     lessee's  contractual  payments were current through March 31, 2009 (and up
     through the date of the Form 10-Q filing) and that the  residual  values of
     the  underlying  assets were not deemed to be  impaired.  The Company  also
     received  strong  indications  from the bankruptcy  trustee that lead it to
     believe that all of the lease  obligations  would be affirmed by the lessee
     or its successor.  Further,  lease payments with respect to this lessee are
     assigned  to a third party  lender as  security  for a loan (March 31, 2009
     balance $1.098 million) that is non-recourse to the Company.

     At March 31, 2009 total exposure of all ATEL related affiliates  (including
     the Company) to this lessee approximates $3.1 million.*
