Exhibit 99

Additional Information



     The following is a description of the relationships between the

Reporting Person and certain related entities or persons that may be

deemed to beneficially own shares of class A common stock, par value

$0.01 per share ("Class A Shares"), and class B common stock, par value

$0.01 per share (the "Class B Shares" and collectively with the Class A

Shares shall be referred to as the "Shares") of the issuer, CompX

International Inc. ("CompX").



      Substantially all of the outstanding voting stock of Contran

Corporation ("Contran") is held by trusts established for the benefit of

Lisa K. Simmons and Serena Simmons Connelly, daughters of Harold C.

Simmons, and their children (the "Family Trusts"), for which Ms. Lisa

Simmons and Ms. Connelly are co-trustees, or is held directly by Ms. Lisa

Simmons and Ms. Connelly or persons or entities related to them,

including their step-mother Annette C. Simmons, the widow of Harold C.

Simmons.  Ms. Annette C. Simmons, Ms. Lisa Simmons and Ms. Connelly also

serve as members of the board of directors of Contran (the "Contran

Board").  Prior to his death on December 28, 2013, Mr. Simmons served as

sole trustee of the Family Trusts.  As co-trustees of each of the Family

Trusts, Ms. Lisa Simmons and Ms. Connelly have the shared power to vote

and direct the disposition of the shares of Contran stock held by

each of the Family Trusts, and Ms. Lisa Simmons and Ms. Connelly each

have the power to vote and direct the disposition of shares of Contran

stock they hold directly or which is held by other entities related to

them.



     Under a voting agreement (the "Voting Agreement") entered into

effective February 3, 2014 by the voting stockholders of Contran, the

size of the Contran Board was initially fixed at five (5) members; Ms.

Lisa Simmons, Ms. Connelly and Ms. Annette Simmons (and, in the event of

their death, their heirs) each have the right to designate one of the

five members of the Contran Board; and the remaining two members of the

Contran Board must consist of Contran management.  The Voting Agreement

terminates in February 2017 (unless Ms. Lisa Simmons, Ms. Connelly and

Ms. Annette Simmons otherwise mutually agree), and the ability of Ms.

Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons to each designate one

member of the Contran Board is dependent upon each of their continued

beneficial ownership of at least 5% of the combined voting stock of

Contran.  In accordance with such Voting Agreement, each of Ms. Lisa

Simmons, Ms. Connelly and Ms. Annette Simmons have been designated as

members of the Contran Board as of February 3, 2014, along with two

members of Contran management.



     Annette C. Simmons is the sole trustee of a trust of which the

beneficiaries are her grandchildren (the "Grandchildren's Trust"), and

she has the power to vote and direct the disposition of the shares the

trust holds. She disclaims beneficial ownership of any shares that this

trust holds.



     A trust for which Ms. Annette Simmons is one of the co-trustees is

the holder of 100% of the outstanding shares of non-voting preferred

stock issued by Valhi Holding Company ("VHC").



     Contran is the holder of 100% of the outstanding common stock of

Dixie Rice Agricultural Corporation, Inc. ("Dixie Rice") and may be

deemed to control Dixie Rice.  Dixie Rice is the direct holder of 100% of

the outstanding common stock of VHC and may be deemed to control VHC.
