Akhilesh Yadav-led Samajwadi Party (SP) declared assets worth nearly Rs. 635 in 2015-16, topping the list of 22 regional parties, according to a report by the Association for Democratic Reforms (ADR), a Delhi-based think tank.

"During the financial year 2011-12, the declared assets of SP was Rs. 212.86 crore which increased by 198% to Rs.634.96 crore during the financial year 2015-16. The total assets of AIADMK between the financial year 2011-12 & 2015-16 increased by 155%, from Rs. 88.21 crore to Rs. 224.87 crore," said the report.

The report that analyses the assets and liabilities of the regional parties between the financial years 2011-12 and 2015-16 is based on audited accounts submitted by the parties to the income-tax department and the Election Commission of India.

The assets declared by the parties fall under six major heads -- fixed assets, loans and advances, FDR(fixed deposit receipts)/ deposits, TDS (tax deducted at source), investments and other assets.

During the financial year 2015-16, the highest asset category was FDR/deposits under which the parties declared Rs. 1054.8 crore. The only asset category to show a reduction in value was "Loans and Advances" - from Rs. 19.75 crore in 2011-12 to Rs. 16.2 crore in 2015-16.

In terms of liabilities, Telangana Rashtra Samiti (TRS) and Telegu Desam Party (TDP) were the top two regional parties.

The liabilities declared by the parties fall under two major heads -- borrowings (from banks, overdraft facilities and sundry creditors) and other liabilities.

TRS declared the highest liabilities (Rs. 15.97 crore) during the financial year 2015-16 though it had declared zero liability during 2011-12. TDP declared liabilities of Rs. 8.186 crore during 2015-16, the report said.
