COLUMBUS -- Republican lawmakers and Gov. John Kasich's administration believe they are in striking distance on a biennial budget deal that funds needed government services and makes adjustments for lower-than-earlier-expected tax collections and other projections.

The two-year spending plan needs to be signed and enacted by Friday, the last day of the current state fiscal year.

Here are a few more numbers you'll probably hear about in coming days:

Four: That's the number of final budget bills that have or will see action, not including numerous different versions that surfaced during committee deliberations.

There's the House version passed back in April, the Senate version that moved a few days ago, the Conference Committee package expected in coming days to be voted on by both chambers and the final version signed by the governor, absent any items he line-item vetoes.

The last is the one that ultimately matters, though the others are important steps along the way.

$65.4 billion: The Senate version of the budget proposed general revenue fund spending of $32.3 billion in fiscal 2018 and $33 billion in '19.

Both totals are lower than spending in fiscal 2016 and estimated totals for the current fiscal year, the latter expected to reach more than $35 billion, according to numbers compiled by the state's Legislative Service Commission.

$1 billion-plus: Kasich, budget Director Tim Keen and legislative leaders announced back in April that they expected to have to make "at least" $800 million in adjustments over the biennium versus the executive budget initially offered by the governor.

The ultimate number, announced by Keen at the start of Conference Committee deliberations, ended up at around $1 billion.

The total included tax collection forecasts reduced by $437 million and $497 million for fiscal 2018 and '19, respectively, as income and non-auto sales tax collections continue to be weaker than earlier projected.

$632 million: House Republicans said back in April that they included about $632 million in adjustments to their version of the budget, via a combination of cuts and revenue increases. The total was less than the shortfall earlier announced but in line with initial budget projections.

$734 million: Senators looked at the House budget, revised some of the savings and spending changes and determined that they would have to tackle $733.9 million in additional adjustments to address the updated revenue forecasts.

Senators accomplished that by adding about $100 million in unspent funds from previous budgets, $71.3 million in monies expected from new lottery games and $15 million anticipated in payments through a tax amnesty program, combined with cutting about $125 million in earlier-proposed agency spending and making hundreds of millions of dollars in additional changes in Medicaid, state prison, school and other programs.

$20-some million: That's what Keen expects lawmakers to tackle during Conference Committee, over and above other adjustments that have already been made.

"We are very close to where we need to be," he told reporters. "[There's] $20, $25 million that would have to be dealt with, [in] my early, rough calculation. I presume there are going to be numerous changes that are made over the course of the next week, and I am certain that we will have a balanced budget, a structurally balanced budget, that the governor can sign."
