On 22/01/1380 AH (2001), parliament authorized the Telecommunication Company of Iran and its provincial subsidiaries to record the telephone-development fees they had received from the Treasury between 1994 and 2000 for telecom infrastructure projects as an increase in the government's paid-in capital in those companies, rather than as ordinary expenditure.
Why this link: Authorizes directing telecom development fee revenue into the state's capital increase in telecommunications companies, a financing instrument for network build-out that plausibly supported the fixed-line, mobile and internet expansion of the 2000s.
Caveat: Telecom expansion in this period was driven mainly by mobile-market liberalization and private operator entry, so this specific capital-injection mechanism's share of subscriber growth cannot be isolated.
Lag: Multi-year, as capital injections fund network rollout over time.
