A. 2. Comment on how the district's government-wide (full accrual) statement of net assets would differ from the balance sheet presented.
In district's government-wide (full accrual) statement of net assets
$ 15 million transferred to debt service fund for principal on bonds would not be payable in current period therefore not taken into Account only interest due of $ 5 million will be taken into Account. Therefore following will be statement of net assets:

Assets: General Funds Capital Projects Fund Debt Service Fund Total
Cash $45 $5 $50
Investments $90 $90
Net Assets $45 $90 $5 $140

Instructional Material:
Please note that following principals are followed in Govt. Accounting
Two basic types of budgets are used by governments and are the same as those used by corporate entities—an annual operating budget and a capital budget. Governmental annual operating budgets include estimated revenues and appropriations for expenditure for a specific fiscal year. Capital budgets control the expenditures for construction projects and fixed asset acquisitions. Operating or capital budgets are recorded in the accounting system as a means of control or compliance.

That is, each type of financial activity is segregated into a separate set of self-balancing asset, liability, and net asset accounts. GASB codification identifies three fund groups— governmental, proprietary, and fiduciary (GASB, 1997, Sections 1100.103 and 1100.105). Governmental funds are used to account for financial resources used in the day-to-day operations of the government. Proprietary funds are those used to account for the government's business-type activities where fees are charged for the services rendered, for example, utility services. Fiduciary funds are those used to account for funds held by the government in trust for others that cannot be used to support the government's programs, for example, an employee pension fund.
The statement of net assets displays information about the government as a whole, reports all financial and capital resources, and assists the financial statement user in assessing the medium-and long-term operational accountability of the government. Separate columns are used to distinguish between the financial data for the governmental activities and the business-type activities that comprise the total primary government. As the term statement of net assets implies, the statement format presents the assets minus liabilities that equal the total net assets, that is, equity. Assets and liabilities are presented in their order of liquidity. That is, assets are presented in the order to their nearness to producing cash, and liabilities are presented in the order to their nearness to consuming cash. Assets and liabilities may be displayed in a classified, current, and noncurrent format if desired. The government's net assets are presented in three components: (1) capital assets net of related accumulated depreciation and debt, (2) restricted net assets with constraints imposed on their use by parties outside the government, and (3) unrestricted net assets.
