  4.  COMMITMENTS
  AND CONTINGENCIES
 
  Operating
  Leases
 
  The
  Company has entered into non-cancelable operating lease
  agreements for locations within the United States and for its
  international subsidiaries, with expirations through July
  2013.  Rent expense in connection with operating leases
  was $1.1 million and $744,000 during 2010 and 2011,
  respectively.
 
  Future
  minimum lease obligations as of December 31, 2011, are as follows
  (in thousands):
 
 
  Purchase
  Commitment
 
  The
  Company has entered into an agreement with one of its suppliers
  to purchase its product through December 2014.  To
  maintain this agreement, the Company is required to purchase a
  minimum of $220,000 of product in 2012.  The minimum
  purchase requirement in the following two years is dependent on
  the volume in the preceding year plus an incremental amount not
  to exceed $40,000.
 
  Employment
  Agreements
 
  The
  Company has employment agreements with certain members of its
  management team that can be terminated by either the employee or
  the Company upon four weeks’ notice.  The employment
  agreements entered into with the management team contain
  provisions that guarantee the payments of specified amounts in
  the event of a change in control, as defined, or if the employee
  is terminated without cause, as defined, or terminates employment
  for good reason, as defined.  In addition, the Company
  has an employment agreement with another employee that can be
  terminated at will by either the employee or the Company,
  provided that the Company must pay a specified amount if it
  terminates the agreement without cause, as defined, or the
  employee terminates the agreement with good reason, as
  defined.  As of December 31, 2011, no outstanding
  obligations existed under any severance agreements.
 
  Consumer
  Indemnity
 
  As
  required by the Door-to-Door Sales Act in South Korea, the
  Company maintains insurance for consumer indemnity claims with a
  mutual aid cooperative by possessing a mutual aid contract with
  Mutual Aid Cooperative & Consumer (the
  “Cooperative”).  The contract secures payment
  to distributors in the event that the Company is unable to
  provide refunds to distributors.  Typically, requests
  for refunds are paid directly by the Company according to the
  Company’s normal Korean refund policy, which requires that
  refund requests be submitted within three
  months.  Accordingly, the Company estimates and accrues
  a reserve for product returns based on this policy and its
  historical experience.  Depending on the sales volume,
  the Company may be required to increase or decrease the amount of
  the contract.  The maximum potential amount of future
  payments the Company could be required to make to address actual
  distributor claims under the contract is equivalent to three
  months of rolling sales.  At December 31, 2010 and
  2011, non-current other assets include KRW 260 million (USD
  $229,000) and KRW 100 million (USD $86,000), respectively,
  underlying the contract, which can be utilized by the Cooperative
  to fund any outstanding distributor claims.  The
  Company believes that the likelihood of utilizing these funds to
  provide for distributors claims is remote.
 Registration Payment Arrangements 
  Pursuant
  to the agreement with the original investors and the placement
  agent in the May 2007 financing for the sale of 1,759,307
  shares of Series A preferred stock and warrants representing
  the right to purchase 1,759,307 shares of common stock (see Note
  5), the Company is obligated for a specified period of time to
  maintain the effectiveness of the registration statement that was
  filed with the Securities and Exchange Commission (the
  “SEC”) covering the resale of the shares of common
  stock issuable upon the exercise of warrants issued in the
  financing.  On March 18, 2010, the Company filed a
  post-effective amendment withdrawing unsold shares from
  registration.  If the Company fails to file a new
  registration statement, and maintain its effectiveness, then it
  may be liable for payment in cash of an amount equal to 2% of the
  product of $1.70 times the number of shares of Series A
  preferred stock sold in the financing to the relevant purchasers,
  or up to approximately $60,000, but only if the quoted closing
  price of the Company’s common stock exceeds the warrant
  exercise price of the warrants.  The exercise price of
  the warrants is $5.00 per share.  Such warrants expire
  May 4, 2013.
 
  Pursuant
  to the agreement with the investors in the Company’s
  October 2007 financing of variable rate convertible
  debentures having an aggregate face amount of $4,250,000,
  seven-year warrants to purchase 1,495,952 shares of the
  Company’s common stock, and one-year warrants to purchase
  1,495,952 shares of the Company’s common stock, the Company
  was obligated to (i) file a registration statement covering
  the resale of the maximum number of Registrable Securities (as
  defined) that is permitted by SEC Guidance (as defined) prior to
  November 18, 2007, (ii) cause the registration
  statement to be declared effective within certain specified
  periods of time and (iii) maintain the effectiveness of the
  registration statement until all Registrable Securities have been
  sold, or may be sold without volume restrictions pursuant to Rule
  144(k) under the Securities Act.  The Company timely filed
  that registration statement covering the shares of common stock
  underlying the debentures, which have been redeemed, and the
  one-year warrants, which have expired.  At the time,
  the 1,495,952 shares of common stock underlying the seven-year
  warrants, and 149,595 shares of common stock underlying certain
  five-year warrants issued to the placement agent in the
  transaction, were not deemed Registrable Securities and were not
  included in the Registration Statement.  If they are
  subsequently deemed Registrable Securities and we fail to file a
  new registration statement covering them, then the warrants may
  be exercised by means of a cashless exercise. The maximum number
  of shares that could be required to be issued upon exercise of
  the warrants (whether on a cashless basis or otherwise) is
  limited to the number of shares indicated on the face of the
  warrants.
 
  As
  of December 31, 2011, no contingent obligations have been
  recognized under registration payment arrangements.
 
  Legal
  Matters
 
  On
  or about January 4, 2010, Steve Francisco sued the Company’s
  subsidiary, NHT Global, Inc., in the Superior Court for Orange
  County, California, in Case No. 30-2010-00333395, styled
  Steve
  Francisco, Starsearch International, LLC, and Healthlik
  Resources, LLC v. NHT Global, Inc., eKaire.com, Inc. and Does 1
  through 20.  Mr. Francisco sought damages for
  the alleged breach of a prior settlement agreement under which
  NHT Global had agreed to pay Mr. Francisco payments of not less
  than $10,000 and not more than $30,000 per month unless and until
  Mr. Francisco violated NHT Global’s policies and
  procedures.  On March 12, 2009, NHT Global had
  terminated payments to Mr. Francisco for violating the policies
  and procedures.  Mr. Francisco sought recovery of
  $100,000 in damages accrued through the date of filing of the
  lawsuit and an order requiring NHT Global to continue making the
  monthly payments required by the settlement agreement, as well as
  an accounting, attorneys’ fees and costs.  Mr.
  Francisco’s lawsuit also sought payment of certain
  promissory notes in the aggregate amount of $102,000 made by
  eKaire.com, Inc., a former subsidiary no longer affiliated with
  the Company, who separately answered the
  lawsuit.  Trial of this lawsuit was set for February
  14, 2011.  On February 14, 2011, the parties announced
  to the court that they had reached an oral settlement agreement
  that was pending documentation.  On or about March 8,
  2011, NHT Global, Inc. and the plaintiffs in this lawsuit signed
  a Confidential Settlement Agreement and Mutual Release,
  containing a mutually agreeable, confidential settlement of the
  case.
 
  On
  or about June 9, 2010, the Company vacated the premises it leased
  at 2050 Diplomat Drive, Dallas, Texas, so that it could be leased
  to a new tenant.  The landlord, CLP Properties Texas,
  LP (the “Landlord”), terminated the lease as of June
  17, 2010 and entered into a lease with a new
  tenant.  On or about August 17, 2010, the Company
  received the Landlord’s written demand for payment of
  $413,000 for unpaid rent and other charges due under the lease
  through June 17, 2010.  On September 30, 2010, CLP
  Properties Texas, LP, sued the Company in the 116th Judicial
  District Court, Dallas County, Texas, in Cause No. 10-13043,
  styled
  CLP Properties
  Texas, LP v. Natural Health Trends Corp. The lawsuit
  alleged breach of the lease and sought actual damages, interest,
  costs and attorneys’ fees.  The Company answered
  with a general denial, and gave notice to the Landlord that it
  intended to assert an affirmative defense of failure to mitigate
  damages.  On or about June 2, 2011, the parties signed
  a Settlement Agreement under which the Company agreed to pay the
  Landlord $50,000 by June 3, 2011 and an additional $75,000 by
  September 15, 2011.  These amounts were timely paid,
  and the lawsuit was dismissed with prejudice.
 
  Currently,
  there is no litigation pending against the
  Company.  From time to time, the Company may become a
  party to litigation and subject to claims incident to the
  ordinary course of the Company’s business. Although the
  results of such litigation and claims in the ordinary course of
  business cannot be predicted with certainty, the Company believes
  that the final outcome of such matters will not have a material
  adverse effect on the Company’s business, results of
  operations or financial condition. Regardless of outcome,
  litigation can have an adverse impact on the Company because of
  defense costs, diversion of management resources and other
  factors.
