National Technical Systems Inc. will repurchase up to 200,000 shares of its common stock through its available cash resources. The Calabasas-based testing and evaluation firm made the decision to buy back its stock as a good use of its cash and to benefit shareholders, company officials said. “The share repurchase plan, coupled with recent special dividends and our increasing book value, represent important returns to our shareholders,” said company CEO William McGinnis. The repurchases can start or stop at anytime and NTS is not obligated to purchase any specific number of shares. Shares in National Technical closed up at $3.75. Mark R. Madler
