Form 10-K for the year ended December 30, 2006
- ----------------------------------------------

Item 8.  Financial Statements and Supplementary Data
- ----------------------------------------------------

20.      Subsequent Event, page 75
- ----------------------------------

1.   We noted in your Form 8-K  dated  January  2,  2007,  that you  determined,
     "Based  upon  our  analysis  of  Cartesian  and  the  transaction,  we have
     determined that the  transaction did not constitute a business  combination
     involving a significant  subsidiary as  contemplated  by SEC rules." Please
     provide us with your tests used to  determine  whether the  acquisition  of
     Cartesian on January 2, 2007, was considered a significant subsidiary under
     Rule 1-02 and Rule 3-05 of Regulation S-X.

     RESPONSE:

     We acquired  Cartesian on January 2, 2007 for a total purchase  price(1) of
     $15.7  million,  of which $6.5 million was not subject to  contingency  and
     $9.2 million was structured as future contingent consideration dependent on
     the  business   meeting  certain   benchmarks.   We  performed  a  detailed
     quantitative and qualitative  analysis in making the determination that the
     transaction  did  not  constitute  a  business   combination   involving  a
     significant  subsidiary under Rules 1-02(x) and 3-05 of Regulation S-X. Our
     calculation  of  the  significance  of  Cartesian  under  the  three  tests
     prescribed by Rule 1-02 and Rule 3-05 of Regulation S-X is provided  below.
     In performing the tests,  we examined the financial  statements of TMNG for
     the fiscal year ended December 31, 2005 (i.e. the registrant's  most recent
     annual  financial  statements  filed  at  or  prior  to  the  date  of  the
     acquisition,  pursuant to Rule 3-05(b)(3)) and the financial  statements of
     Cartesian  for the fiscal year ended August 31, 2006 (i.e.  the  acquiree's
     most recent annual financial statements, pursuant to Rule 3-05(b)(3)).



- --------
(1) The amount of contingent consideration disclosed in our Form 10-Q's filed
during 2007 for the Cartesian acquisition increased from that shown in the Form
10-K for the fiscal year ended December 30, 2006 primarily due to a
reclassification from non-contingent consideration to contingent consideration.

           Cartesian  total  assets  are less  than 20% of TMNG's  total  assets,
           therefore the Cartesian  subsidiary  is not  significant  based on the
           Asset Test.

        Cartesian Earnings as % of TMNG Loss                                     [***]%

           Cartesian  income from  continuing  operations  before income taxes is
           less than 20% of the  absolute  value of TMNG's  loss from  continuing
           operations before income taxes,  therefore the Cartesian subsidiary is
           not significant based on the Earnings Test.

           Our  investment  in Cartesian is less than 20% of TMNG's total assets,
           therefore the Cartesian  subsidiary  is not  significant  based on the
           Investment Test.

           For purposes of  determining  the amount of  contingent  consideration
           included in the Investment Test calculation,  we followed the guidance
           of the SEC's Staff Training  Manual (Topic Two,  I.D.1.a) which states
           the investment test should  "...include  contingent  consideration  as
           part of the total  investment in the acquiree unless the likelihood of
           its payment is remote."

           We determined  that the  likelihood of payment of GBP [***] (or $[***]
           million) of the  contingent  consideration  was remote  based upon our
           review, in connection with

(4)  Conversion  from GBP to USD was based on the  exchange  rate for January 2,

(5)  Contingency  is based on various Year 1 operating  results  (e.g.,  working
     capital, revenue, EBITDA).  Likelihood of payout is considered greater than
     remote based on projections for year 1.
(6)  Sellers are able to increase  purchase price by 35% of EBITDA  generated by
     Cartesian  over a four year period.  The amount  included in the Investment
     Test  represents  the amount whose  likelihood is  considered  greater than
     remote.
