The Price Commission, somewhat fearful that its policies might not reduce the rate of inflation to its year end goal of 2.5 per cent, announced yesterday it would tighten up a bit on future price increases by large companies.</br></br>Price Commission officials predict that further changes in commission regulations will be forthcoming, but caution that none of the changes will be ?ÛÏradical.?Û?</br></br>The commission trimmed the average price increase a firm can reefeive in its flexible Term Limit Pricing agreements to 1.8 per cent from 2 per cent. It said, however, that the new cap would neither affect firms who already have TLPs with a 2 per cent cap or firms currently in negotiation for them.</br></br>The TLP agreements permit a firm to raise individual prices flexibly provided the average price increase during the year for the company remains under a certain specified percentage?ÛÓ now 1.8 per cent or below.</br></br>The commission ruling, which came on a 4-2 vote, also prohibits the company from raising the price of any individual product more than 8 per cent. The earlier TLP arrangements had no cap on the prices of any particular product, though a commission spokesman said individual TLP agreements did contain such caps.
