Integrated Physicians & Associates, an investor$-$owned company, had the following account balances at the end of $2020$:

Gross patient services revenue $($total charges$)$ $$975,000$

Contractual discounts and allowances to $3$rd$-$party payers $$250,000$

Charges for charity $($indigent$)$ care $$100,000$

Estimated bad debts $($implicit price concessions$)$ $$50,000$

a$.$ Calculate the net patient service revenue amount that would be shown on Integrated Physicians & Associates' income statement for the year ended December $31,2020.$

b$.$ Suppose the $2020$ contractual discounts and allowances balance reported above is understated by $$50,000.$ In other words, the correct balance should be $$300,000.$ Assuming a $30\%$ income tax rate, what would be the effect of the misstatement on Integrated Physicians & Associates' $2020$ reported:

i$.$ Net patient service revenue?

ii$.$ Total expenses, including income tax expense?

iii. Net income?

For each item, indicate whether the balance is overstated, understated, or not affected by the misstatement. If overstated or understated, indicate by how much.
