OTES PAYABLE AND LONG-TERM DEBT
 
On
September 18, 2015,
we executed a Promissory Note and Business Loan Agreement with BOKF, NA d/b/a Bank of Texas (“BOKF”), which provides us with a line of credit facility of up to
$6,000,000
and is secured by our inventory.   On
August 10, 2017,
this line of credit was amended to extend the maturity to
September 18, 2019. 
The Business Loan Agreement contains covenants that requires us to maintain a funded debt to EBITDA ratio of
no
greater than
1.5
to
1
and a “Fixed Charge Coverage Ratio” greater than or equal to
1.2
to
1.
  Both ratios are calculated quarterly and are based on a trailing
four
quarter basis.  For the
three
-month periods ended
March 31, 2018
and
2017,
there were
no
amounts drawn on this line.
 
Also on
September 18, 2015,
we executed a Promissory Note and Business Loan Agreement with BOKF which provides us with a line of credit facility of up to
$10,000,000
for the purpose of repurchasing shares of our common stock pursuant to our stock repurchase program, announced in
August 2015
and subsequently amended, which permits us to repurchase up to
2.2
million shares of our common stock at prevailing market prices through
August 2018. 
On
August 25, 2016,
this line of credit was amended to increase the availability from
$10,000,000
to
$15,000,000
for the repurchase of shares of our common stock through the earlier of
August 25, 2017
or the date on which the entire amount is drawn.  On
August 10, 2017,
this line of credit was further amended to extend the drawdown period and conversion date from
August 25, 2017
to
August 18, 2018
to align with our stock repurchase program.   During this time period, we are required to make monthly interest-only payments. At the end of this time period, we expect that the principal balance will be rolled into a
4
-year term note. This Promissory Note is secured by a Deed of Trust on the real estate located at
1900
SE Loop
820,
Fort Worth, Texas.   For the quarter ended
March 31, 2018,
we drew approximately
$541,000
on this line which was used to purchase
72,400
shares of our common stock.  There were
no
amounts drawn on this line during the quarter ended
March 31, 2017. 
At
March 31, 2018,
the unused portion of the line of credit was approximately
$7.1
million.
 
Amounts drawn under either Promissory Note accrue interest at the London interbank Eurodollar market rate for U.S. dollars (commonly known as “LIBOR”) plus
1.85%
(
3.672%
and
3.351%
at
March 31, 2018
and
December 31, 2017,
respectively).
 
At
March 31, 2018
and
December 31, 2017,
